A.CY AND GOOD JUDG MENT. PRE FA C E. THIS treatise is the result of an effort to give the profession, in a con- densed form, the accepted doctrines and approved procedures of Modern Surgery. I have endeavored to write a practical work, giving the surgical principles and operative methods generally accepted and practised by the leading surgeons of the world at the present time. The opinions of the best authorities, the methods of the most practical surgeons, and the well-established facts of surgical science are discussed; but the consider- ation of theories, historical questions, traditional views and operations, and innovations of undecided value has been rigidly avoided. The value of an author's discretionary power in such rejection or acceptance of material depends upon the carefulness of his analysis and the impartiality and soundness of his judgment. It has been my aim to bring these essentials to the work; hence, the statements of the volume represent my appreciation of the questions that have presented themselves. In order to depict the present state of modern surgery I have con- sulted standard text-books and current surgical literature. The best and newest thought is usually found in the latest editions of monographs; therefore much use has been made of such works. I am indebted to my friend Dr. Thomas S. K. Morton for writing the sections on Diseases and Injuries of the Joints, Diseases and Injuries of the Genito-urinary Organs, Dislocations, Excisions, Amputations, and the index. Without his efficient aid the publication of the volume would have been greatly delayed. Dr. Morton and Dr. C. L. Bower have given me much aid in reading the proof-sheets and in seeing the book through the press. J O H. N. B. R O B E R T S. 1627 WALNUT STREET, PHILADELPHIA.

DEFINITION, CAUSEs, VARIETIES, EXTENSION OF INFLAMMATION. DEFINITION.—The process of inflammation, though of paramount importance to the surgeon and the subject of profound study and observation, is not easily definable. Its elementary features are unknown, because it is a vital process which the microscope cannot study except by its results. Hence, attempts to define inflammation are mere statements of its symptoms and effects. The word refers to the changes observed in animal structure following an injurious influence insufficient to cause immediate loss of vitality. This initial factor may originate from with- out, extrinsically, as a blow; or from within, intrinsically, as in inflam- mations due to deleterious elements circulating in the blood-current. Inflammation, according to the present condition of pathological science, may be described as a peculiar molecular change in the walls of the small bloodvessels, dependent upon an extrinsic or an intrinsic irritation, which increases the adhesion of the blood to the vessel walls and allows permeation of the blood elements through them. Until the blood elements are allowed to escape by the abnormal permeability of the vascular coats, inflammation may be said not to exist. Inflammation is not strictly a disease. It is Nature's reparative effort to overcome the perturbations caused by an injurious influence on the animal organism. There are three terms, to which authors have given somewhat different applications, that, on account of their relationship to the process of in- flammation, require explanation at this time. I give to them the definition which seems most logical, in the attempt to bring order out of the exist- ing confusion. Hyperamia is an unusual amount of blood in the vessels, due to any cause whatever. A hyperaemia due to physiological causation, as in glands during active secretion, in the skin in blushing, and in erectile structures, is called a determination of blood. Hyperaemia resulting from imperfect venous return, due to mechanical pressure on veins, gravity, or diminished cardiac power, is called congestion, which term should be employed only in this restricted sense. Hyperaemia produced by an increased amount of blood thrown into a part is often denominated “active congestion,” but this tends to produce confusion. For practical 3 34 I N F L A M M A TI O N . purposes this form of hyperaemia is the first step toward inflammation, and, though often no sensible effusion occurs, it might, with considerable propriety, be styled inflammatory hyperania. Hyperaemia and inflammation have a close relationship, since hyperaemia whether physiological, mechanical, or active, if continued, leads to effusion and exudation, and inflammation at once exists. When inflammation subsides, hyperaemia is left as the last step toward restoration of the part to health. To indicate inflammation of a structure the termination “itis” is added to the name indicating the structure affected, as synovitis, pleuritis. CAUSES.—The causes of inflammation are: the exciting or determining, which give rise to the actual outbreak of inflammation, and the predis- posing, which have previously created a tendency that requires merely an exciting cause to initiate the inflammatory process. Exciting causes may be local, as in injuries, and constitutional, as in syphilis. Predis- posing causes, in like manner, may be local, as in the weakness of an organ resulting from previous inflammations, and constitutional, as in inherited or acquired impairment of bodily vigor. A given cause may be at one time an exciting, at another a predisposing, cause. For example, hyperaemia due to increased functional activity of an organ may be the exciting cause of inflammation; again, the same hyperaemia of the same organ may be the predisposing cause to which an irritation, acting as an exciting cause, must be added to induce the outbreak of inflammation. Inflammation due to external injury is called traumatic, that without definite assignable cause idiopathic. The latter term must not be under- stood as implying that inflammation can arise without a cause. The cause is always present, but may elude our search. Inflammation cannot spread unless its cause has extended its area of influence, nor can it per- sist without a similar persistence of its causation. In considering the causes of inflammation it must be remembered that there are two factors in its etiology—the cause which exerts an exciting influence, and the tissue upon which such influence is exerted. In some cases the exciting cause acts without any predisposition of the tissue being present, while, at other times, the same exciting cause cannot pro- duce inflammation unless the normal resisting power of the tissue is lowered. This impaired resistance of the tissue may result from either an acquired or an inherited predisposition. It is seen, therefore, that the predisposing cause of inflammation may be anything which has a ten- dency to lower the health of the body, or the health of any part of the body. Among causes which may induce inflammation there are some which are perfectly obvious and easily detected. These produce what are often called simple traumatic inflammations. Under this head may be included mechanical and chemical injuries; injuries due to the appli- cation of heat or cold; those due to electricity, which causes electrolysis of the fluids, or to prolonged anaemia, or bloodlessness, of the part. Ex- cessive functional activity and nervous influences are said to produce inflammation. Such inflammations do not tend to spread beyond the site originally subjected to injurious influences, nor to increase in severity after the application of the exciting cause has ceased. In fact, the height of the inflammation is reached soon after the receipt of the injury, and the inflammation rapidly subsides. The irritation and consequent inflammation produced by a chemical agent does not, however, always show itself at the point at which the chemical agent gains admission to the body. Examples of this are seen C A U S E S, 35 in instances of inflammation of the internal organs, such as the kidneys and liver, produced by the absorption of drugs through the skin or stomach. Alcohol, for instance, produces chemical inflammation of the liver. Certain drugs, on the other hand, act injuriously on the kidneys, by which organ they are eliminated from the blood. These are instances of inflammation due to chemical causes, but widely different, of course, from the inflammation of the skin produced by powerful caustics, where the inflammation is produced at the point of application of the agent. Rheumatic and gouty inflammations are perhaps due to a similar action of chemical agents in the blood. The inflammations due to what is ordinarily called exposure to cold or wet are probably associated with an irritation of the vessels, due to driving the blood from the surface of the body to the internal organs. Many inflammations whose causation was formerly obscure, and which were, therefore, called idiopathic, are now believed to be due to the presence of vegetable organisms. These fungi, which are variously called bacteria, microbes, and microörganisms, multiply in the fluids of the human body, and therefore furnish continuously acting causes. In- flammations resulting from these fungi, or microscopic plants, may be due to the mechanical or chemical action exerted by them. There is a very great variation in the severity or type of inflammation due to these organisms; some of them are very virulent, causing at once gangrene, others cause a suppurative inflammation, and still others a chronic inflammation. The variety of inflammation may be fibrinous, suppurative, or productive. One of the most important inflammations produced by these fungi is that form which is called tuberculous. From what has been said, it is easily perceived that these organisms have indi- vidual characteristics. That form which produces a certain disease can- not produce any other disease, but such other disease is caused only by another form of organism having a different life history. Again, there are many organisms which, by entering the fluids of the body, do not, so far as known, produce any form of inflammation or dis- ease. These are called non-pathogenic organisms in contra-distinction to those above referred to, which are called pathogenic organisms. In studying the microbic, or mycotic, origin of inflammation it must be remembered that the inflammation is not due to the mere presence of the microbes within the body, because, under ordinary circumstances, the normal resistance of the tissues to pathogenic processes prevents the occurrence of inflammation. In other words, bacteria moving freely in the blood-current may not inflame the tissues. Certain contingencies are requisite before their deleterious influence can be exerted. It is necessary that the organisms shall be arrested so as to be able to multiply and pro- duce irritation; because, it requires a large number of these organisms in the tissue to produce a pathogenic change. Such arrest of bacteria may be caused by the processes of embolism or thrombosis, or by injury to a bloodvessel by which an extravasation of blood takes place into the connective tissue surrounding the capillary vessels; or they may be filtered out of the lymph-current by the lymph-glands. These processes which allow the microörganisms to come to rest and settle may be the needed factor which shall cause the advent of inflammation. It may occur that, notwithstanding the arrest of bacteria, no inflam- mation occurs because there is no predisposition in the tissue at the point of arrest, or, in the general system of the patient, to suffer from microbic 1I] Wasl OI). 36 I N F L A M M ATION This makes clear to us what is meant in the preceding paragraph by “predisposing causes of inflammation.” Any circumstance which results in a depression of the vital powers, such, for example, as the continued abuse of alcohol, or prolonged anxiety and exhaustion, may induce a general or constitutional predisposition to inflammation. Bruises which cause extravasation of blood may act as a local predisposing cause; as, indeed, may any variety of wound. Wounds which are open to the air, by giving entrance to microörganisms upon the surface of the body and in the air, are much more prone to inflammation than subcutaneous wounds, since the latter exclude the bacteria which are external to the patient's body. Some bacteria will cause inflammation only when they gain access to a certain kind of soil which is favorable for growth and development. Portions of the body, for instance, may be too cold for their development, in which event inflammation will not occur or will be arrested. If, how- ever, these same organisms happen to become located in some part of the body which is warmer, they multiply and may at once excite inflamma- tion. This illustrates what has been said before, that each organism has its peculiarity which must be accommodated in order to allow its devel- opment and pathogenic action. These microscopic plants are just as particular as to the kind of soil in which they grow, and as to the cir- cumstances surrounding their growth, as are the trees with which we come in contact in the larger world. Certain conditions of the blood, such as diabetes and Bright's disease, are particularly favorable for the development of certain forms of bacte- rial life and consequent inflammations. The occurrence of inflammation depends upon other conditions than those already mentioned. The species of organism with which wounds and tissues are affected is a factor of imporance. Some organisms are much more virulent than others. Again, the number of organisms which gain access to the tissues is a matter of importance. It can easily be understood that if but a small number infect the animal or human being, they can be destroyed or ren- dered inert by the normal resistance of the tissue. It is known that the leucocytes have a tendency to surround germs and to enclose them so as to prevent their acting upon the tissues. At other times the leucocytes or white blood-cells appear to eat up the bacteria, and hence are called phagocytes. If, however, the dose of pathogenic organisms is very large, or relatively large compared with the resistant power of the tissues and the leucocytes, inflammation will be induced. It is a curious fact that the growth of several organisms together may induce inflammatory results, which no one of them alone is capable of effecting. This is seen in the harmful effects resulting from the associa- tion of putrefactive organisms and pus-causing organisms. In this in- stance it is probable that the putrefactive bacteria destroying the granu- lation tissue which may be present, allow the pyogenic fungi to gain access to the general circulation. It is believed, also, that some organisms act antagonistically to other species of fungi. A patient inoculated with erysipelas becomes immune to infection with the anthrax bacillus. The poison from microörganisms may be attenuated by certain labora- tory methods of handling the fungi. If they are cultivated outside of the animal body, and not passed through some animal for a long period of time, they soon diminish in virulence. There are other methods of MIC RO6 RG ANISM S ASSOCIATED WITH DISE As E. 37 cultivating these organisms, which in a similar way weaken or attenuate the poison. It is stated that the poisonous qualities may also be increased by similar manipulation in the bacteriological laboratory. MICROöRGANISMS WHICH ARE ASSOCIATED WITH DISEASE. The pathogenic vegetable parasites or fungi are of three kinds—bac- teria, yeasts, and moulds. The first are the organisms to whose action most of the infective diseases are attributed. The disease which we call thrush, and which is characterized by grayish patches forming upon the mucous membrane of the mouth and adjacent parts, is due to a parasite which is one of the yeasts. A number of skin diseases are caused by the growth of pathogenic moulds. Favus, tinea tonsurans, tinea sycosis, and pityriasis are instances of parasitic skin diseases due to moulds. Actino- mycosis is thought to be due to a fungus belonging to this class. It will be seen, therefore, that, for the surgeon, yeasts and moulds have little interest, while the first class, or bacteria, are of Supreme importance. It should be remembered by the student that the word bacteria is used very loosely by many to refer to all the kinds of parasitic fungi. It is better, however, to restrict it, as I have done, to a single class, to which is given the name schizomycetes. Bacteria are characterized by their method of multiplication, which is either by division, or by the forma- tion of spores. Yeasts, however, multiply by the budding process; while the moulds have a more complicated method of multiplication or reproduction, and are characterized by numerous threads which interlace and form the mycelium. It is sufficient for our purpose to describe the different forms of cells which characterize the bacteria. If the cells are spherical or egg-shaped, the fungus is called a coccus; if the cells are straight rods, the fungus is called a bacillus; if the rods are curved, the name vibrio is used; when the plant assumes a more twisted form, it is called spirilla. These four terms, then, are used to give an idea of the shape of the plant, a single cell of which constitutes an individual. These cells may be grouped together in various ways. If the round or oval cells show a tendency to grow together in groups somewhat like bunches of grapes, the fungus is called a staphylococcus, or grape-coccus; if the same shaped cells always grow in straight chains, like beads upon a string, the plant is called a streptococcus, or chain-coccus; if there is a tendency for two round or oval cells to keep close together, but separate from other cells, the fungus is called a diplococcus. These remarks make clear the terms used to describe the fungi found in surgical diseases. The streptococcus pyogenesis, in accordance with its name, a pus-causing chain-coccus; whereas the staphylococcus pyogenes is a pus-causing grape-coccus. There may be several kinds of staphylo- Qoccus or streptococcus, each of which has a distinctive adjective added to its name. Thus we have the white pus-causing grape-coccus and one of a golden color which has a similar pathogenic action. In multiplying, as has been said, schizomycetes, or fission fungi, to which have been given the name bacteria, divide so as to form two or more individual cells. Some of them, however, multiply by the forma- tion of spores, round or oval bodies, which grow within or from the cells, and subsequently become separate individuals. Some of these 38 I N F L A M M AT I O N . microörganisms have the power of motion and are called, therefore, motile forms. The various forms differ from each other in the character of food which they require; though carbon, hydrogen, nitrogen, phosphorus, sulphur, magnesium, and potassium are needed, probably, by all. The presence of water is necessary for the development of fungi; therefore, thorough drying prevents multiplication of fungi, and, in some cases, kills them. Some require oxygen, which others can do without. The temperature to which they are exposed has also an important bearing on the life and development of nearly all forms. They are killed by boil- ing, or by a degree of heat very little above the boiling-point, provided that moist heat is used. Dry heat does not destroy them until it reaches a point considerably above the boiling-point. The bacillus of malignant pustule is of all pathogenic microörganisms the most difficult to destroy by heat. Spores will resist a higher degree of heat and more changes of condition without loss of vitality than will fully developed fungi. Bacteria are found in the air, in the water, in the earth, and upon the external surface of the human body. These organisms in large numbers, both pathogenic and non-pathogenic, are found under the nails and in the various folds of the skin, such as the axilla. They are also numerous upon the mucous membranes which come in contact with the air, such as the bronchial and intestinal mucous membranes and those of the mouth and oesophagus. In many instances they do no harm, even if pathogenic ; because of the resistance of the tissues to their action, which is great when the vitality of the tissues is unimpaired, or because of the com- paratively small number which gain access to the tissues. Under favor- able circumstances, however, multiplication is very rapid, and one indi- vidual may become many millions in twenty-four hours. - It has previously been stated that the mere presence of pathogenic organisms in the blood-current is not sufficient to give rise to disease. This, according to present pathological views, can only occur when the circumstances are favorable to their development within the body, and the resisting power of the tissue to their injurious action is imperfect. The antagonism of the tissues to microbic invasion tends to prevent disease, unless the number or dose of infecting germs is too large to be successfully repelled. The leucocytes may form a wall or barrier around the bacteria, and, thus hemming them in, prevent their dissemination through the body; or they may be taken into the interior of the leuco- cytes and their vitality be destroyed. VARIETIES.—All forms of inflammation are either acute or chronic. The acute is rapid in course or severe in symptoms, the chronic slow in progress or less severe in symptoms. It will thus be seen that the terms acute and chronic (perhaps improperly) each contain two ideas—one refer- ring to time, the other to severity. The word subacute is used to express an intermediate severity between acute and chronic, but has no reference to time. Hence inflammation, as to time, is termed either acute or chronic ; as to severity, it is expressed as acute, subacute, or chronic. Although inflammation is essentially the same in whatever tissue it may occur, the character of the exudate varies in accordance with the resistance of the tissue, the intensity of the injurious causative influence, and the time of action of that influence. These variations in the exudate may often be found in the same inflammation by examining different areas of inflamed structure. Serous Inflammation. — In serous inflammation the exudate is characterized by a small amount of albumin and few leucocytes, being, W A. R. I. ET IF. S. 39 indeed, very slightly different from the normal transudate of healthy tissues. This fluid does not coagulate. Instances of serous inflammation are seen in pleuritis with effusion, arthritis, hydrocele, and in inflamma- tory oedema of connective tissue. This form of exudate may be expected after slight or momentary injuries, in the early stages of more severe in- flammations, and in cases where the blood is impoverished. Fibrinous Inflammation.—Fibrinous inflammation gives rise to an exudate containing larger quantities of albumin and more leucocytes, and hence more coagulable. It forms, upon free surfaces and in the sub- stances of organs, that which is clinically denominated “lymph.” Lymph, then, is an inflammatory product consisting of fibrin and entangled leuco- cytes. It is sometimes called plastic lymph, to show that it is entirely different from the fluid called lymph which circulates in the lymphatic vessels. The best examples of this form of inflammation are seen in the serous membranes, such as the peritoneum and pleura, and in the long continued or chronic inflammations of slight intensity in connective tissue. At times we find a grade of inflammation intermediate between these forms, which may be termed sero-fibrinous inflammation. These varieties of the inflammatory process may end by absorption of the exudate, which is accomplished by the leucocytes returning into the circulation by first entering the lymphatic vessels, and by the fibrin and some of the leucocytes undergoing fatty degeneration previous to such absorption by the lymphatic system. Suppurative Inflammation.—In this very common form of inflammation the exudate contains the same elements as in the fibrinous, but does not coagulate. No lymph, therefore, is deposited, or, if any lymph has been deposited by the previous form of inflammation, it is destroyed by the accession of the suppurative stage. It is thus seen that the so-called varieties of inflammation are rather stages, or degrees, of the process. Suppurative inflammation is the result of a more irritative or longer con- tinued cause than the serous or fibrinous forms. Acute suppuration is another term signifying the same process. If the suppuration is circumscribed in an abnormal cavity, the resulting condi- tion is called abscess; if diffused in the tissues, purulent infiltration. Pus contained in a normal cavity, such as the pleural sac or knee-joint, is called a purulent effusion. If suppuration occurs upon a free surface of mucous membrane the condition is called purulent catarrh, provided the epithelium of the mucous surfaces is not destroyed; while it is called ulceration if the epithelium and subjacent tissue are destroyed. Suppuration attack- ing a cutaneous surface also gives rise to what is called ulceration. Productive Inflammation.—When the exudate of a serous or fibrinous inflammation becomes converted into new connective tissue, the inflam- mation is termed productive, because of the formation of this new struc- ture. This process is accomplished by the fibrin disappearing and numerous leucocytes coming into the lymph, after which vascular loops from the capillary vessels of the inflamed structures penetrate the lymph and become surrounded by young cells. This new tissue, consisting of capillary loops and young cells, which have developed within the sub- stance of the lymph, is called granulation tissue. Granulation tissue may be converted into connective tissue, often called scar tissue; it may de- generate into typical tubercles; it may become material looking like pus, but which is not true pus; or finally, it may actually break down 40 I N F L A M M ATIO N. into pus, the inflammation assuming the character of suppurative inflam- mation, which it then is. The second transformation of granulation tissue gives rise to what is variously called “chronic” or “cold’ abscess and chronic suppuration in bone. MODES OF EXTENSION.—Inflammation cannot spread unless its cause extends before it; hence, inflammations due to mechanical and chemical irritants do not spread beyond the point at which the irritation was first exerted. All those inflammations which tend to spread from the original site are probably due to microbic causes. It may be taken for granted, in accordance with the present state of pathological knowledge, that the spread of inflammation is due to vegetable parasites. Such inflammations spread in three ways—by continuity of tissue, by the lymph-current, and by the blood-current. { When inflammation spreads by continuity of tissue, the bacteria which have settled there are spread into the surrounding tissues by being carried thither by leucocytes and by the lymph-channels. This mode of exten- sion of an inflammatory process is comparatively limited in its action. When mycotic inflammation spreads by the lymphatic vascular system, the bacteria are carried along by the current in the lymphatic vessels until they reach the first gland, where they are filtered out by the ramifi- cations which the current makes in passing through the interstices of the gland. After being arrested thus they multiply and act as an exciting cause of inflammation, producing in the gland a secondary inflammation which is located at a considerable distance from the primary disease. This is quite different from the method of extension just described, where the fungi travel a short distance only in the lymph-current, or are carried short distances by the white blood-cells, choosing, as they do, the paths of least resistance. The blood-current may carry bacteria to all parts of the body, but they are innocuous, as a rule, until they are arrested by ex- travasation, by clotting of the blood, or embolic plugging of the vessels. Under these circumstances, secondary or metastatic inflammation occurs. Pyaemia is a good example of such metastatic inflammation. The inflam- mation of mumps being carried to the breast and testicle is a similar example of metastatic inflammation. PATHOLOGY, SYMPTOMs, AND TERMINATIONS OF INFLAMMATION. PATHOLOGY-The study of the pathological or essential nature of in- flammation must be divided into a consideration of the rôles played by (1) the nerves, (2) the small blood vessels, (3) the blood, and (4) the tissues. The changes occurring in each of these, though in the main synchronous, must be investigated separately. 1. Nerves.—The agency of nerves is really unknown. The vaso-motor nerves may have a causative influence in the dilatation of the vessels, due to a reflex action following irritation of the part affected; but of this nothing definite can be asserted. Recent researches show pretty conclu- sively that inflammatory phenomena depend on a direct injurious influence upon, and a vital alteration of, the walls of the blood vessels, without the necessity of any direct nervous agency. 2. Bloodvessels.—As has been previously stated, the essential factor or lesion of inflammation is the change that occurs in the walls of the small bloodvessels, by which the friction between the wall and the blood-current P A TEIO L O G. Y. 41 is increased and the wall is made more porous. In inflammation of non- vascular tissues, such as the cornea and cartilage, the same vascular alterations take place in the vessels which surround these structures, and upon which their nutrition depends. The vascular phenomenon of inflam- mation is dilatation of the arteries, capillaries, and veins; followed by acceleration, with subsequent abnormal retardation, of the blood-current. Mere acceleration of blood-flow not followed by abnormal retardation does not constitute inflammation, though it may lead to it. The dilata- tion of the vessels and the abnormal retardation of the current must be per- manent. A preliminary contraction of the capillaries is at times seen, but it is not an essential factor. While vascular dilatation and blood retardation are being established, the white corpuscles accumulate, especially in the venules, and the red corpuscles generally in the capillaries, until stagnation or stasis of the current occurs. This stage of absolute cessation of motion is preceded by one in which is seen a mere oscillation of the vessel contents synchronous with the cardiac pulsations. Synchronous with these vascular changes there occur permeation of the blood elements through the vessel walls and increased absorption by the lymphatic vessels. 3. Blood.—The white corpuscles (leucocytes) are relatively increased in inflammatory blood, and show a tendency to keep near the walls of the vessels. They are less heavy than the red corpuscles, and hence are thrown to the margin of the blood stream. Inflammatory blood when drawn shows more fibrin than non-inflammatory blood. This condition of hyperinosis and the buffy coat, formerly considered diagnostic of in- flammation, have no diagnostic or therapeutic value. During inflamma- tion white cells migrate through the walls of the venules, and red cells are pressed, as it were, through the walls of the capillaries into the sur- rounding tissues. This escape is supposed to occur through small open- ings (stomata) resulting from stretching of the walls of the dilated vessels. There is no emigration from the vessels in which absolute stagnation has taken place, nor from the arterioles. The escape of the white corpus- cles usually greatly exceeds that of the red, and the vessels soon become surrounded and obscured by the crowd of extra-vascular leucocytes. In intense inflammations in very vascular tissues the red escape in greater numbers than the white corpuscles, and a resulting hemorrhagic spot is visible to the naked eye. The number of migrating cells is increased in the later stages of the inflammatory process. It is possible for the emigrated leucocytes—(1) to be transformed into tissue cells; (2) to re- enter the bloodvessels; (3) to enter the lymphatic vessels; (4) to become pus-cells. There also occurs an escape or exudation of fluid derived from the blood liquor and similar to it, which, when associated with the escaped white and red blood corpuscles and the proliferating cells of the inflamed tissues, con- stitutes the inflammatory exudation, or, as it has been termed by some writers, inflammatory lymph or fibrin. The escaping fluid differs from the simple serous or dropsical effusion, that occurs in congestion or mechanical hyperaemia, in that it contains more white corpuscles, more albumin, and is more prone to spontaneous coagulation. It differs from blood liquor, or liquor sanguinis, in having less albumin and less coagula- bility. I prefer to call this inflammatory fluid an evudation of lymph, or simply an evudate, and the escape arising from venous distention a trans- wdation of serum, or simply a transudate. This exudate or inflammatory lymph is of paramount importance to 42 IN FLA M M ATION. the surgeon, for, by its organization and transformation into tissue anal- ogous to that at the seat of injury or disease, hemorrhage is prevented, wounds united, abscesses circumscribed and limited, plastic surgery made possible, and other reparative surgical processes accomplished. At times, however, it produces morbid conditions, strictures, and adhesions, alters structure by interstitial deposit, and is exceeding destructive to functional integrity. It is well, it seems to me, to apply the term exudate, or lymph, to effusions. occurring from inflammation, even when they closely resemble the serous transudate of mechanical venous obstruction. The milder forms of in- flammation give rise to a fluid containing so little albumin and having so little tendency to coagulation that it is impossible to distinguish it from the fluid of a non-inflammatory dropsy. If, however, inflammation exist, let this be called lymph; if inflammation does not exist, call it a transu- date or serum. On mucous or serous surfaces the exudate is readily seen during the progress of inflammation; in some tissues it is exhibited as swelling; in the cornea and other non-vascular structures it is found surrounding the part, because it is the adjacent vessels which present the inflammatory alterations. The blood phenomena of inflammation, then, are migration and evudution. 4. Tissues.—The tissues are swollen and infiltrated with the escaping blood elements, and the proper cells of the tissue involved show disordered nutrition, such as coagulation-necrosis and fatty degeneration. The im- pairment of nutrition may result in the formation of inferior tissue, sup- puration, or gangrene. The peptonizing action of microörganisms has to do with the inflammatory destruction of tissue, and thus aids the malign influence of the chemical and physical changes wrought by original injury and the deluging of the tissues with escaping blood-elements. Within the tissues there is proliferation or multiplication of the white blood-cells which have escaped from the vessels; but multiplication of the proper or native cells of the tissue does not take place, except when repair or regeneration of tissue is going on coincident with inflammation of only moderate intensity. This proliferation must not be considered as a part of the inflammatory process. During inflammation the tissue ele- ments are obscured by the intermingled white corpuscles and filaments of fibrin; and the structures are changed in physical consistence, being sometimes softer than normal, at other times harder. The tissue alteration of inflammation, then, may be described as dis- turbance of nutrition associated with proliferation of white blood-cells. t The phenomena of inflammation may finally be thus formulated: 1. Nerves: Unknown, or possibly vaso-motor influences. 2. Bloodvessels: Permanent dilatation of calibre associated with per- meability of walls. 3. Blood: Permanent abnormal retardation of current associated with migration and exudation. 4. Tissues: Disturbances of nutrition associated with proliferation of white blood-cells. It was formerly held that the native or tissue cells also underwent proliferation. SYMPTOMs.-The local symptoms of inflammation are those exhibited at the point at which the process is going on; the constitutional or general symptoms are manifested by the patient's organism as a whole and are observable in functional derangement of the various organs without any necessary relation to the situation of the inflammatory changes. The SY M P T O M S . 43 general symptoms imply an existing inflammation, but do not indicate its locality. The local symptoms are pain, discoloration, swelling, heat, and disordered function. It requires the co-existence of a number of these abnormal manifestations to constitute inflammation, and one or more may be prominent or entirely absent, according to the variety of the inflammation and the nature of the inflamed tissue. Pain is a subjective symptom of inflammation, while the other manifesta- tions are, for the most part, really objective physical signs. The pain of inflammation is due to pressure of the exudate on nerve-endings and possibly to chemical irritation exerted upon them; is persistent; is in- creased by motion and the dependent position; and must be distinguished from the paroxysmal pain of neuralgia and spasm. Its severity depends more upon the tissue affected than the degree of inflammation, and is often inverse to the amount of swelling possible, because the pressure of the distended vessels and exudate upon the nerve filaments is increased when the structures are too dense to allow swelling. Pain may be reflected by nervous distribution to a part remote from the seat of disease, as occurs in coxalgia; in such cases it is not strictly a local symptom. Throbbing pain, which is due to increased tension at each pulsation of the heart, is usually indicative of the advent of suppuration. The discoloration usually varies from the shades of red, the usual hue, to those of purple and blue. It is essential that the alteration in color be permanent, for the transient hyperaemia of merely physiological causation also produces redness. In the cornea, arachnoid, and similar non-vascular structures the change is manifested by a whitish opacity and a loss of lustre, while the surrounding vascular tissues present the usual inflam- matory redness. In iritis there is a loss of lustre and a brownish dis- coloration. The blackness of gangrenous tissue and the whiteness of necrotic bone have been erroneously instanced as illustrations of inflammatory altera- tion of color, but, since inflammation ends at the moment death of tissue occurs, these are not strictly inflammatory discolorations. The cause of the red discoloration in inflammation is the abnormal amount of blood in the vessels, and, perhaps, at times, a real staining of the tissues by the coloring matter of the corpuscles. As resistance to flow of blood increases because of change in wall of vessels and pressure from exudate, the parts become bluish, or mottled and pale. The temperature of an inflamed part is usually increased. It is fre- quently above 100°F. There is no production of heat at the inflam- matory focus, but the increase is due to the increased rapidity of the arterial circulation. A local increase of heat in chronic inflammation may be imperceptible; hence, for example, we speak of “cold” abscesses. Inflammatory swelling is due to the increased amount of blood in the Vessels and to the migration and exudation which occur. If the exudate consists principally of fluid the part is said to be cedematous; and a de- pression made in the surface by pressure of the surgeon's finger is apt to remain for a few moments as a little pit. This “pitting” does not show if the tissues are tensely stretched. It is most typical in oedema from mechanical hyperaemia. Usually the exudate is cellular rather than fluid and the swollen tissues are too hard to pit. Swelling is always great in those parts, such as the scrotum, formed largely of loose con- nective tissue, because there is less resistance to the escape from the Vessels of inflammatory products. In dense resisting structures and under 44 I N F L A M M A TI O N . tense fasciae much swelling is impossible; and hence, great pain is exper- ienced during inflammation in such localities. The tissue-pressure thus induced may lead to gangrene by totally obstructing circulation, if not relieved by free incisions to allow escape of fluids and to relax distended structures. The occurrence of swelling is frequently beneficial by dimin- ishing the intravascular pressure. If the exudate is small in quantity and the lymphatics carry it off, no swelling will exist. This occurs in slight grades of inflammation. Disordered function is a symptom (sometimes subjective and sometimes objective) always present, and attracts attention when the other manifesta- tions of inflammation are more or less in abeyance. The increased or impaired sensibility of the 'sense organs; the irritability of the hollow viscera; the modified secretions of the various glands; and the alteration of nutrition, shown by defective absorption, by atrophy and hypertrophy, are all well-known instances of functional disturbance arising from in- flammation. The injury inflicted upon every tissue by the morbid process readily explains the functional disturbance. The general or constitutional symptoms of inflammation are grouped together and called inflammatory or symptomatic fever, because the in- crease of the general bodily temperature is such a characteristic member of the group. The terms traumatic fever and surgical fever are some- times employed as synonyms of inflammatory fever when the inflamma- tion is due to an injury. Inflammatory fever varies with the intensity, extent, and locality of the process, and with toxic influences associated with it, and is practically absent in slight inflammations of unimportant localities and when microbic infection of the blood is prevented. It de- pends on the presence in the blood of products of the morbid tissue- change occurring at the seat of inflammation, or of poisonous principles manufactured at the seat of injury by microorganisms of a vegetable nature. The most important duty of the surgeon is to protect all acci- dental or operation wounds from infection by these vegetable parasites, which, under the general name bacteria, enter the blood-stream and are believed to be responsible for all grave degrees of inflammatory fever. Inflammatory fever, in other words, is usually a poisoned condi- tion of the blood due to microörganisms. Inflammatory fever becomes prominent within twenty-four hours after the incipiency of the local symptoms. There are two types of constitutional disturbance in inflam- mation : the sthenic, representing excess of force; the asthenic, repre- senting want of force. The irritative type, so-called, is not a special form, as all cases are necessarily either sthenic or asthenic. The respiratory, circulatory, digestive, nervous, secretory, and other gen- eral symptoms accompanying inflammation show modifications accord- ing to the type of the constitutional disturbance; hence, as the treatment must greatly vary in the two conditions, the necessity of an early recogni- tion of the type is evident. The constitutional symptoms of inflammation, when asthenic, resemble those of typhoid fever; hence, they are often said to belong to the “typhoid condition.” The student must remember, however, that typhoid or enteric fever and the “typhoid condition,” though presenting similar symptoms, are dif. ferent entities. The following table shows the differential diagnosis of typical cases of sthenic and asthenic inflammatory fever : T. R. E. A. T M E N T . 45 Sthenić. Asthenic. Patient . . . .

TERMINATIONS.—There can be but two terminations of inflammation. First, gradual return of the tissues to health without destruction of their elements and functions; and second, death of these tissues, which may take place molecularly or in masses large enough to be readily seen. When inflammation terminates in the first manner the walls of the blood- vessels are restored to their normal condition, the deposits absorbed and the damaged tissues regenerated. Resolution is then said to have taken place. In the second instance, if death occur molecularly, that is, if small particles die, it is called ulceration if in soft tissues, and caries if in bone; while death in mass of soft parts is termed gamgrene; of bone, necrosis. It should be observed that pathologists apply the term necrosis to all forms of tissue-death, whether in bone or soft structures, in mass or in small particles. When the surface of an inflamed mucous membrane suffers death and is covered with a gray, yellowish or reddish membrane, which is tough and adheres to it, the inflammation is said to be of a diphtheritic character. Such gangrenous inflammations occur on the conjunctiva or any other mucous membrane, and may attack wounds. They are infective inflam- mations and take their name from the disease diphtheria, which often, but not always, gives rise to a pharyngeal inflammation of this character. Not all diphtheritic inflammations, however, are diphtheria. These mem- branes differ clinically from the layer of lymph which ordinarily forms on inflamed surfaces by the great difficulty with which they are detached. The results or sequences of inflammation, such as newly organized tissue, adhesions, effusions, exudations, pus, sloughs, and sequestra must not be confounded with its terminations. It can only terminate either in a return to health of the tissues inflamed or in the death of the same. The parts in the vicinity may continue in a state of inflammation, but the death of tissue, by either ulceration or gangrene, effectually terminates the inflammatory process in that particular issue. Resolution is the termination of inflammation which the surgeon ordi- marily aims to secure, but in many instances it is impossible to obtain it, and suppuration, ulceration, or gangrene occurs. Hence, after considering the treatment to be pursued in the endeavor to obtain resolution, I shall discuss suppuration, ulceration, and gangrene. TREATMENT.-The most important precept that can be taught in rela- tion to the management of inflammation is this: Inflamed structures tend to recovery as soon as the cause of inflammation is removed. Hence, when the surgeon can remove the cause the rest of the treatment consists in merely waiting for the reparative efforts of nature, and in averting any secondary irritative action that may supervene. When the obscurity of 46 IN FLAM M ATION. the cause precludes its removal, efforts must be made to avert the advance and the destructive effects of the inflammation, until the cause ceases to be operative. The indications of treatment in all cases of inflammation, then, are to remove the cause and to establish resolution as promptly as possible. Removal of the cause is to be effected on general rational principles: for example, a foreign body is to be extracted from the tissues; the patient himself is to be transported from unfavorable surroundings; or, if the cause lie in some vitiated state of the blood, remedies to remove that state are to be administered. Attempts to remove the cause are not justi- fiable, however, if they render the patient liable to conditions more dan- gerous to life than that for which he is being treated, for it must always be remembered that the surgeon is treating a condition rather than an entity. Resolution, if possible, is to be induced by local and constitutional measures. The latter, of course, includes hygienic and dietetic as well as medicinal agencies. After injuries and operations the surgeon desires the presence of reparative inflammation to heal the wounds, and, there- fore, little is required except attention to prevent the occurrence of inor- dinate inflammatory action. The prevention and arrest of microbic infection of wounds is the most important duty of the surgeon in this connection. The means by which these ends are to be accomplished will be discussed under Treatment of Wounds. The local treatment of inflammation is properly discussed before the constitutional, because many cases of minor severity demand no constitu- tional treatment whatever. Inflammation is treated locally by (1) posi- tion and functional rest; (2) cold ; (3) heat; (4) anodynes; (5) blood- letting; (6) diminishing arterial supply; (7) antiseptics and necrotics; (8) stimulants and astringents; (9) counter irritation; (10) compression and friction. Position and functional rest.—Rest from functional activity and that position which renders afflux of blood to the part most difficult are essentials in treating inflammation, especially when acute. Elevation and immobility of the parts are, therefore, usually to be enforced, sup- plemented in many cases by confinement to bed. Cold.—The depressant and sedative action of cold is utilized as a pre- ventive of inflammation, and, in the earliest stages of the process, to limit its severity. It should not be employed when suppuration or mortifica- tion is to be feared, nor, as a rule, in chronic inflammation. Cold and moisture may be applied by cold baths, rapidly evaporating lotions, or by irrigation in which a constant application of water, simple or medi- cated, is maintained by allowing it to drop on cloths laid over the inflamed part. Dry cold is obtained by using tubes or rubber bags filled with cold water or ice. Heat.—Heat is practically always combined with moisture, because all warm applications soon become saturated with secretions from the skin. Hot dressings are properly used when there is pain and tension, a tendency to suppuration, and a probability of mortification. They aid in mortifying processes by causing separation of the sloughs, thus promoting the suppura- tive action beneath the dead tissue. Heat is usually indicated when cold is contra-indicated. It may be obtained by local baths of hot water or steam, fomentations, poultices, etc. Any warm or hot application combined with moisture acts as a poul- tice if evaporation be prevented by rubber cloth, waxed paper, or other T R E A T M E N T . 47 } impervious covering. The protracted use of heat is objectionable because it causes relaxation of tissue. When suppuration is inevitable deep incision is preferable to poultices, because it relieves pain promptly, pre- vents destruction of tissue, and hastens cure. It is probable that the value of moist heat is largely due to its increasing the migration of white blood cells, which thus, by their numbers, become more powerful in their antagonism to the microörganisms causing the inflammation. Anodynes.—The narcotics, especially the preparations of opium and belladonna, are frequently beneficial by relieving the pain of inflamma- tion. Extract of belladonna, softened with water and smeared over the surface, and opium combined with acetate of lead are favorite prescriptions. Local bloodletting.—The direct abstraction of blood from engorged vessels and the opportunity of escape afforded deposits infiltrating the tissues are the means by which puncture, Scarification, incision and wet cupping act as potent agencies in combating inflammation. At times it is not practicable to incise the vessels and tissues of the inflamed organ, and then wet cupping or leeching at an adjacent point is done to relieve the hyperaemic structures. As a rule the bloodletting should be applied at the focus of inflammation, and the bleeding encouraged by warm appli- cations. The advantage of incision over poulticing has been mentioned previously. Cutting off arterial supply.—This is done be applying pressure upon, or by ligating in its continuity, the main artery, and thus diminishing the supply of blood to the inflamed member. Ligation has seldom been resorted to, except experimentally; but intermittent digital pressure or partial compression by compresses is occasionally judiciously employed as a prophylactic measure after operations on the extremities. Antiseptics and necrotics are adapted to the treatment of wounds, and are usually employed as prophylactics to prevent excessive inflammation liable to occur from pyogenic or putrefactive bacterial infection or from inoculation of animal poisons. The use of carbolic acid, corrosive sublimate, beta-naphthol, and similar agents, will be described in discussing the antiseptic treatment of wounds. The most efficient necrotics to prevent absorption of the poison of hydrophobia, snake-bites, etc., are the actual cautery, strong nitric acid, and acid nitrate of mercury. Immediate excision is prefer- able when it can be adopted. Stimulants and astringents.-These local remedies, of which nitrate of silver and acetate of lead are examples, occupy a high rank in the treat- ment of inflammation, especially of mucous membranes. The more chronic the inflammation the stronger must be the stimulant and astrin- gent impression. Counter-irritation is applied at a point more or less remote from the inflammatory focus, and varies in degree from mere redness of the skin to vesication, suppuration, and complete destruction of the skin as by the actual cautery. Except in the mildest form, as obtained by sinapisms, counter-irritation is seldom used in acute inflammation. It probably acts by abstracting blood from, and lessening the textural excitability of, the inflamed organ. Compression and friction.—Compression, by means of muslin or elastic bandages or adhesive strips, and friction, or manipulation (massage), either with or without oils and liniments, are most efficient means of relieving muscular spasm and of producing absorption of deposits in chronic and the late stages of acute inflammation. 48 I N F L A M M A TI O N . CONSTITUTIONAL TREATMENT.-The general or constitutional manage- ment of inflammation comprises: 1. Abstraction of blood by vene- section. 2. Increase of secretion and elimination by cathartics, dia- phoretics, diuretics, and emetics. 3. Diminution of vascular tension by cardiac depressants. 4. Increase of vascular tone by tonics and stimu- lants. 5. Decrease of nervous excitement by anodynes. 6. Reduction of temperature by antipyretics and the general application of cold. 7. Correction of morbid conditions of blood by alteratives and specifics. 8. Regulation of sanitary surroundings and diet. These measures, however, as well as the local means, are not all to be employed in each instance of inflammation, for, while some are appro- priate to the sthenic type, others are adapted to asthenic cases. More- over, it is to be remembered that many medicinal agents have a com- bination of activities, being, at the same time, evacuants, anodynes, and cardiac depressants; hence, one or two remedies will often meet all the requirements. |Venesection.—In the early stages of acute sthenic inflammation, when the after-depression from loss of blood will be less detrimental than the threatened destruction of the integrity of a vital organ, general blood- letting is beneficial, Venesection acts mechanically by lessening the amount of blood in the system, and, therefore, relieves inflammatory engorgement, which may be the most disastrous factor of the inflamma- tory process demanding treatment. This is especially true of pulmonary and cerebral inflammations. Vascular engorgement, however, is the result, not the cause of inflammation, and removal of blood is not re- moval of inflammation. Venesection should never, as a rule, be employed when the pulse is feeble and frequent and the symptoms those of asthenia, nor when it is probable from the activity of the inflammatory attack, as in blood-poisoning, that depression will shortly follow. w Catharties, diaphoretics, diuretics, and emetics, are internal remedies of value; because they increase glandular secretion, which is arrested in in- flammatory fever, act as derivatives by attracting blood to other organs, deplete by drawing away the watery constituents of the blood, expel irritating substances from the system, and have a refrigerant or cooling effect. t Depressants.-Aconite, veratrum viride, and antimony are the cardiac sedatives most frequently employed to reduce the high vascular tension, exhibited by the full, bounding, frequent pulse of acute inflammation occurring in robust, plethoric persons. They are selected when the de- pressing influence of venesection is considered unwarrantable. Tomics and stimulants.-Asthenic inflammations, on the other hand, require from the first, quinia, iron, digitalis, alcohol, and highly nutri- tious food, to increase cardiac power and sustain life under the depressing effects of the inflammatory process. The same remedies are usually needed after the subsidence of active sthenic symptoms, which leave the patient emaciated and exhausted by the severity of the structural changes that have taken place. Anodynes.—Pain, restlessness, and general nervous excitability call for the administration of opiates, chloral, the bromides, sulfonal, hyoscin, and kindred drugs, to give physiological and functional repose. The beneficial effect on inflammatory fever of a few hours' profound sleep is familiar. Cold.—Sponging the surface of the body, cold packs, and cold baths are certainly effectual in diminishing bodily temperature, and are CONSTITU TI O N A L T R E A T M E N T. 49 employed advantageously in inflammatory affections. Antipyrine, anti- febrin, and similar drugs with a known ability to lower the general temperature are often valuable remedies. Alteratives and specifics.-Certain inflammatory lesions are best com- bated by specific remedies, which have some alterant or eliminating blood action and which should be given as soon as the diagnosis is estab- lished. As examples may be mentioned mercury and the iodides in syphilitic inflammations, quinia in malarial, and colchicum in gouty lesions. Mercury, because of its supposed antiplastic action, was long given in all inflammations to lessen the deposition of lymph, but this belief has deservedly, I think, lost ground. The removal of inflamma- tory products in chronic conditions is certainly effected by the so-called sorbefacients, among which the preparations of mercury, iodine, and ammonium chloride stand prečminent. Sanitary and dieletic measures.—Cleanliness of person and of surgical dressings, freedom from microbic and deleterious atmospheric influences; regulation of the temperature of the room; proper ventilation; freedom from noise and anxiety; good nursing and judicious diet are more im- portant than any one requirement heretofore mentioned under the consti- tutional treatment of inflammmation. Acute sthenic cases may require some restriction of diet, but not the starvation treatment of past genera- tions of surgeons. Asthenic inflammation invariably requires concen- trated, easily digestible food at frequent intervals. In conclusion, a recapitulation of the differential therapeutic indica- tions of sthenic and asthenic and of acute and chronic inflammations may be instructive. Sthenic cases present symptoms of overaction, and require depleting, depressant, and non-stimulant remedies, with restricted diet. Asthenic cases present symptoms of depression, and require corrob- orant, tonic, and stimulant remedies, with abundance of nutritious food. Acute inflammations, being either sthenic or asthenic, require treat- ment according to their type, with depleting and soothing applications locally. Chronic inflammations, being usually more or less asthenic in type and characterized by much inflammatory deposit, require tonic and alterative treatment, with stimulating applications locally. C H A P T E R II. SUPPURATION. MENTION of suppurative inflammation has been made in a previous section, but, so important is the relation of the suppurative process to operative surgery and surgical pathology, that it is necessary to consider a little more fully the clinical history of this pathological condition. Suppuration, or the formation of pus, is due to causes which are sufficiently intense and sufficiently prolonged in their action to give rise to suppura- tive inflammation, and which have the peculiarity of preventing the formation of fibrin in the inflammatory exudate. According to present pathological views, it is believed that the yellow liquid called pus, laud- able pus according to the older writers, never occurs except when vege- table fungi are present. In some other cases there is a liquid found which is often called pus, but which is not true pus. This kind of fluid is found in so-called chronic abscesses, in bone abscesses, and under other circum- stances. It is preferable to call it a puriform liquid, and restrict the term pus to the creamy discharge that escapes from acute abscesses and ulcerated surfaces. Let it be understood, then, that for the clinical purposes of the surgeon pus never occurs except in association with microörganisms, and, therefore, does not occur in inflammation of a simple traumatic kind, unless the seat of the inflammation becomes infected with fungi. There are about twelve vegetable parasites which are known to cause the formation of pus; those most frequently found are the staphylococcus pyogenes aureus, the staphylococcus pyogenes albus, and the streptococcus pyogenes. The first two are grape coccusses, while the streptococcus is a chain- coccus; the two former usually produce circumscribed suppuration and abscess, while the streptococcus is usually the cause of spreading and diffuse suppuration. The importance of this connection between organisms and suppuration is very clear, because it indicates at once that great care must be taken to prevent infection, in simple traumatic inflammations, with germs from the hands of the surgeon, his instruments, or dressings. Pus is a yellow or greenish-white, alkaline fluid, presenting character- tistics varying with the peculiarities of the inflammation producing it. It consists of a liquid in which float white corpuscles. The pus liquor is composed of water, albumin, fats, and salts, and is derived from the blood, with the liquid portion of which it seems to be almost identical. It con- tains, however, the pus-forming microörganisms and their chemical products. The corpuscles are, in fact, the migrated leucocytes referred to in the section on the pathology of inflammation, which have now lost their vitality. Some of them are still capable of changing their shape and migrating, and are considered to be the white blood-cells which have just escaped from the vessels. As usually seen under the microscope the corpuscles are dead, and have lost the amoeboid movements of the living cells. A B SC ESS, 51 Pus has a tendency to cause liquefaction and disintegration of the tissues with which it comes in contact. It may itself occasionally be absorbed after fatty metamorphosis, or be changed into a caseous mass; as a rule, however, if not evacuated by operation it is discharged through an opening produced by its disintegrating action on the overlying tissues. It may be secreted from a free, unbroken surface, as in inflammation of mucous membrane, and constitutes most of the discharge in all cases of ulceration. VARIETIES.—When a granulating surface in a healthy person is pro- gressing favorably toward cicatrization the pus secreted is of a creamy consistence, and has a specific gravity of about 1030, yellow color, and little or no odor. These features, therefore, pertain to what was formerly called healthy, or laudable pus. The so-called unhealthy pus is fre- quently, though not always, thin, of low specific gravity, of a dirty yellow or reddish color, and has often an offensive smell, and a tendency to irri- tate the skin. It is termed ichorous, or sanious pus. Other adjectives are used to describe various conditions and appearances of pus; thus curdy, gummy, scrofulous, Sanguinolent, contagious pus, and muco-pus are terms often heard, but most of them are indefinite and unscientific. At the present time the occurrence of pus is believed to be due to infection of the wound by microörganisms; hence no pus can be called healthy. Wounds, however severe, will, if kept free from organisms, heal without puS. TESTs.-Pus mixed with other fluids can be detected by the addition of Solution of potassa, with which it forms a gelatinous mass. This and other tests, however, are inferior to microscopic examination, which discloses the characteristic FIG. l. spheroidal semi-transparent corpuscles, from Gr 5 sººth to ºth of an inch in diameter, con- gº tº taining granules and nuclei. The nuclei are É º • *-*. made more distinct by the addition of dilute § @ (3) acetic acid.

(GREEN.) Microscopic examination with suitable illu- mination and sufficiently high oil-immersion lenses will bring to light the microörganisms to whose presence the suppurative action is due. ABSCESS. DEFINITION.—An abscess is often described as a collection of pus cir- cumscribed by a wall of lymph, or as an abnormal cavity containing pus; while suppuration occurring within the meshes of the connective tissue without such limiting wall is called a purulent infiltration, and a segretion of pus from a mucous, serous, or granulating surface, a purulent effusion. These distinctions are frequently ignored, however, for a “diffused" abscess is an impossibility if abscess means a circumscribed cavity filled With pus; and certainly the expression, “abscess of the knee-joint,” is more, common than “purulent effusion in the knee-joint.” It would be less confusing to define an abscess simply as a cavity containing pus, 52 SU PP U R A TI O N. without any restrictions as to a limiting wall or to the nature of its sur- roundings. There is certainly no etymological objection to this use, which is certainly in accordance with the ordinary signification of the word. The symptoms, diagnosis, and local treatment of pus in the normal sacs and cavities, as the pleural cavity and knee-joint, and in newly-formed spaces in the connective tissue are the same; and they are practically, in both cases, abscesses. VARIETIES. Acute abscess.--When pyogenic organisms are arrested in the tissues they multiply and cause coagulation-necrosis in the cells. To prevent the injurious effects of these organisms a large number of leucocytes appear in the region affected, and, by their endeavor to prevent encroachment of the microörganisms upon other tissues, form a wall around the group of germs. The antagonism between the organisms and the leucocytes is kept up until the Wall of granulation tissue created by the action of the white blood-cells is too dense for the microörganisms to penetrate. It is thus that the suppurating focus is circumscribed ; within this wall the tissue cells break down, and under the peptonizing influence of the micro- organisms the formation of fibrin in the exudate is prevented. The cavity of the abscess, therefore, contains dead leucocytes, microörganisms, and their chemical products, and destroyed tissue cells, in addition to in- flammatory exudate. These constituents make up the creamy liquid which is called pus. The tendency of the pus contained in this cavity is to soften the sur- rounding tissue and to spread in the direction of least resistance until it is discharged through an opening upon a free surface. This is called the pointing or spontaneous opening of an abscess, Such a spontaneous opening relieves the tension, which has been one of the causes of the continuance of the inflammation, and permits the pus and microörgan- isms to be evacuated. The collapse of the walls of the abscess and the adhesion of the opposite surfaces readily complete the cure, if the admis- sion of putrefactive bacteria is prevented. In the event of putrefaction taking place, suppuration continues for a comparatively long time, according to the situation and the character of the abscess. Healing of the abscess may be hastened by the surgeon open- ing the cavity and evacuating its contents long before the pus reaches the surface; but, in this event, it is equally important that the operation should be dome antiseptically, since the admission of putrefactive and pyogenic germs would keep up the inflammation and the Suppuration, as it would after spontaneous evacuation. Very rarely the pus of an acute abscess may become encapsulated and undergo caseation or calcification; the mass in a sort of Sac may then remain in the tissue as an innocuous tenant for many years, though it forms a spot of least resistance at which inflammation may readily be set up at any future time. Diffused suppuration frequently occurs and causes what is often called diffused abscess. The process is of similar pathological nature to that just described, but the pus is not enclosed in a distinctly limited cavity. The condition is due to a more intense inflammation, and is usually believed to be due to the presence of the pyogenic strepto- coccus, which has a more intense peptonizing influence on the cells than the mycotic causes of such suppurations as are limited by a distinct barrier of cells. Sloughs and shreds of gangrenous tissue are often found commingled with the pus of diffused suppuration. A BSC ES S. 53 The acute or phlegmonous abscess necessarily corresponds in symptoms with acute inflammation, of which it is a result. The advent of suppur- ation in the progress of acute inflammation is often marked by rigors and great constitutional disturbance; after which the throbbing local pain, the shining red skin, and the acuminated appearance indicate that an abscess is being formed. The pus usually produces softening of structure, and tends to escape toward a free surface. The consequent elevation of the overlying tissues is distinctive of an abscess about to point, and, as the skin becomes thin over the advancing pus, the characteristic yellow color becomes apparent, after which a small slough is separated, leaving an orifice through which the pus is discharged. The walls of the abscess then collapse, and the cavity is filled up like an ulcer by the granulating process; in fact, an abscess within the tissues has been called a “closed ulcer.” Deep abscesses may produce very little change upon the surface, except a localized Oedema. Metastatic abscesses are essential elements of pyaemia, and will receive consideration under that heading. The so-called chronic or cold abscess, which is probably usually a lesion of tubercular inflammation and is, therefore, slow in progress, does not exhibit very active local symptoms. It is apt to occur in connection with bones and lymphatic glands and in persons of the so-called scrofulous habit, but may be found in any region and in any patient. There is no heat of skin, little or no cutaneous redness, no pain, and generally no tendency to pointing. The skin becomes thin over the puriform collec- tion and an orifice by which the contents escape may form after a long time; but, instead of the pointed elevation of an acute abscess, there is seen a general rounded protrusion of thin and purplish integument. The puriform liquid is confined by a thick wall, forming a tough sac lined with velvety elevations, and is usually thin in consistence, containing cheesy masses, ill-formed corpuscles, and cholesterin crystals. It is not pus in the strict sense, and should be discriminated from that which is found in acute abscesses. Chronic or tubercular abscesses often become very large, because they do not tend to spontaneous evacuation. If we do not consider the fluid in these so-called chronic abscesses to be pus, and it certainly differs from pus, the term abscess is inappropriate. The term, however, is still retained because of its convenience. DIAGNOSIS.—Acute abscesses are diagnosticated by the history of pre- ceding acute inflammation, the superficial oedema, the throbbing pain, the appearance of pointing, the sense of fluctuation, and in cases of doubt by the use of an exploring needle or by the withdrawal of some of the pus with a hypodermic syringe or aspirator. Chronic abscesses are distin- guished by the absence of symptoms pointing to aneurism, cystic tumors or malignant growths, by the negative history, the possibly depraved constitution of the patient, oedema, fluctuation, and by aspiration. Fluctuation is the wave caused by the displacement of fluid when pressure is suddenly made upon the swelling. It shows the existence of liquid Contents, but gives no indication of their character. It may be obtained by placing the fingers of the two hands on opposite sides of the suspected abscess and making intermittent pressure or striking sudden taps. In small collections it is better to grasp the swelling between the thumb and fore-finger of one hand, and make the parts tense, while intermittent pressure is made by the fore-finger of the other hand. The transmission of the impulse proves that the contents are fluid, but other symptoms 54 SU P. PU R A TI ON . must be investigated to determine whether pus, serum, or blood is con- tained in the tumor. The opening of an abscess must always be an aseptic procedure. After the incision the interior of the sac should be thoroughly scraped out with a curette and made perfectly aseptic by means of irrigation. This removes all pus and microörganisms. The cavity, if small, may then be sewed up so as to bring the walls together and allow healing. If the abscess be a large one it may be needful to provide for drainage by the use of drainage-tubes. This is especially necessary in large cavities that cannot be thoroughly scraped and disinfected. Dressings should be antiseptic in character, as a rule, and should exert some pressure so as to cause collapse of the walls of the cavity. TREATMENT.-Since abscess is the result of mycotic inflammation, the local and constitutional means previously described, as appropriate for the cure of inflammation by resolution, should be adopted when suppura- tion is threatened. A blister is often very serviceable, and seems to dissi- pate the suppurative inflammation. If it is found that resolution is im- possible, rapid maturation and evacuation of the abscess are to be obtained, and restoration of the parts to a normal condition promoted. Hot and moist applications, such as poultices, soften tissue and encourage rapid migration of leucocytes; hence, they are, perhaps, proper when resolution and absorption seem hopeless. Poultices are very little used since the advent of the antiseptic era, and more early operative interference than formerly is usual. To relieve the pain and tension, and prevent disfigur- ing scars and destruction of tissue, early evacuation, by means of a free incision made with a sharp knife, is imperatively demanded in all cases of acute abscess. Incision made before pus has actually formed will often cut short the suppurative process, and, if made sufficiently free to relieve tension, always lessens the pain. If there is danger of wounding large vessels the abscess may be opened on a grooved director, or it may be torn open with a blunt instrument after incision of the skin. Sometimes this last procedure is well done by inserting the end of a pair of closed forceps and forcibly opening the ends of the blades. In all cases where the cavity is large the orifice should be kept open by a tent made of a piece of antiseptic gauze, or by a drainage tube; and permanent pressure should be applied by means of a bandage, in order to hasten contraction and granulation of the sac of the abscess. Counter-openings may be necessary when the pus infiltrates the connective tissue or burrows or gravitates into pouches which prevent its ready escape. In tubercular abscess the treatment is the same. The evacuation of many fluidounces of puriform liquid may, by exposing the wall of the abscess to the air with its septic influences and by the sudden relief of pres- sure to which the surrounding capillaries were accustomed, lead to rigors, exhaustive fever, and grave constitutional symptoms. Hence, as the fluid is sometimes, though very rarely, absorbed, and chronic abscesses may remain without pointing for indefinite periods, it was formerly the custom with many to abstain from operative interference. This is inju- dicious, for, withdrawal of the so-called pus by the aspirator, and the application of firm pressure, or incision and disinfection under the strictest antiseptic precautions, are now believed to be the best surgery. Hyper-distention of large abscess cavities with antiseptic solutions forced in by means of a syringe tightly fitting a small opening, is often a good procedure to be adopted as soon as most of the contents have been allowed to escape. Thus air is excluded, the customary pressure main- U L C E R A TI O N. 55 tained, and constitutional symptoms lessened. These various antiseptic measures are useful in acute abscesses, but are even more essential in large chronic abscesses. Supporting remedies and anodynes are important in all cases of severe or prolonged suppuration. The local treatment of all abscesses, then, whether acute or chronic, should be early and free incision with strict antiseptic precautions. The best watery solutions to use in washing out small abscess cavities are corrosive sublimate (1 : 1000 to 1 : 5000) and betanaphthol (1 : 2500). As there is some risk of poisoning if large quantities of the sublimate solutions remain in large and irregular cavities, that drug must be used with caution. Betanaphthol is not poisonous, but is not so active a germicide. Solution of iodoform in ether (1 : 50 to 1 : 500) is a good material for injecting the cavities of tubercular abscesses. In all cases the solution, of whatever character, is subsequently allowed to flow from, or is pressed out of, the abscess cavity. SINUS AND FISTULA. When an abscess has been evacuated it may not contract and heal completely, but, especially when the muscles prevent perfect rest, may leave a long, narrow, and sinuous canal through the tissues. This is lined by a membrane having somewhat the character of mucous membrane, from which unhealthy pus is discharged. If the canal has only one orifice it is called a sinus; if more than one, a fistula or fistule. The term fistula in surgery is sometimes limited to such a canal communicat- ing with one of the hollow organs, as the bladder, rectum, or lachrymal sac. The orifice of a fistula or sinus is usually surrounded by exuberant granulations projecting as a papilla. Sinuses and fistules are cured by destroying the adventitious lining membrane and setting up acute inflam- mation, in order to cause healthy granulations to take place from the bottom. This may be done by irritating injections, the actual cautery, curetting, or by laying the track open with the knife or elastic ligature which thus controls all muscular contraction; and in many cases still better by dissecting the whole canal out and approximating the healthy wound so made with sutures. Any source of irritation, such as diseased bone or foreign material, must be removed at the same time. The term fistule is also applied to a communication between two hollow viscera, due to injury or sloughing. Such abnormal openings are cured by plastic operations. 4. ULCERATION. When inflammation does not terminate by resolution in a return to health, death of the part by either ulceration or gangrene must take place. Ulceration is death in small particles or molecules; gangrene is death in masses large enough to be seen. Similar processes in Osseous tissue are called caries and necrosis, and will be described under diseases of bone. The causes of ulceration are the same as the causes of inflam- mation, to which ulceration always owes its existence. It may occur Superficially, as in the skin and cornea, or deeply, as in the substance of organs, for abscesses and sinuses are practically but the results of ulcera- tion. The ulcerative process is more common in skin, mucous mem- branes, cartilages, lymphatic glands, lungs, and bone (called caries), than 56 SU PP U R A TI ON . in fibrous, serous, or muscular tissue. Ulceration consists in softening and disintegration of structure, followed by the removal of the débris by absorption and ejection. When removal of tissue is effected by absorp- tion alone, as is seen in erosion of tissue from aneurismal pressure, the term interstitial absorption is applicable, since ulceration causes removal chiefly by discharges. Ulceration and suppuration are closely allied, since some of the pus owes its existence to the destruction and disintegration of tissue. Sloughs and foreign bodies in the tissues are usually thrown off by ulceration and suppuration occurring around them. Ulceration, then, is the molecular death of soft tissues, and produces on a free surface the anatomical lesion called an ulcer or open sore. ULCERs. DEFINITION.—An ulcer is a breach of continuity of surface, covered by granulations and usually accompanied by a discharge of pus. The nature of the granulations and of the pus determines the character of the ulcer. The solution of continuity may be due to the process of ulceration, to gangrene, or to a wound; for in gangrene the slough is separated by ulceration, and wounds that do not heal by first intention become ulcers as soon as granulation is instituted. A solution of continuity called an ulcer is usually deeper than the epithelium ; if not, the terms abrasion, desquamation, or excoriation are commonly applied. Among exceptions to this rule may be mentioned superficial ulcers of the cornea. Surgeons are called upon to treat ulcers of the skin and mucous mem- brane, and to these alone are the following paragraphs meant to apply. VARIETIES.—All ulcers are direct consequences of the inflammatory process, which is due to either constitutional or local causes. The causa- tion is an important factor in the treatment of ulcers, but does not require any change in the classification of them. Ulcers are healthy or unhealthy. The healthy ulcer is typically illus- trated by the Sore produced when granulation has begun in a wound made by cutting out a portion of tissue. The edges are regular and smooth, and slope gradually toward the granulations, which are red, pain- less, do not bleed under gentle pressure, secrete a serous non-purulent fluid, and never protrude above the surface of the skin. The granula- tions at the circumference are being covered by or converted into a bluish- white cicatricial pellicle of epithelium, while the skin surrounding the ulcer is purplish and somewhat hardened by inflammatory infiltration. All ulcers must be brought to this condition before cicatrization can occur, and so long as the ulcer continues healthy, healing goes on spon- taneously and steadily, if the surface be only protected from injurious contact. Protection is best effected by applying a piece of aseptic rubber tissue or oiled silk covered with an aseptic or antiseptic gauze dressing. Some surgeons prefer antiseptic ointments, such as carbolized oxide of zinc ointment, boric acid ointment, and ointment of petroleum ; or lotions or powders containing some germicidal agent. Unhealthy ulcers are those accompanied by some condition which pre- vents their exhibiting the characteristics above mentioned. If undue inflammation be present, as shown by great heat and pain, Oedematous surroundings, engorged granulations, and discharge of pus mixed with blood, it is an inflamed ulcer. If this process be violent and rapid, de- U L C E R S. 57 struction of tissue and extension of ulceration occur, a pellaceous mass is seen covering unhealthy-looking granulations, and the edges become irregular and sharp-cut. This constitutes a “sloughing” ulcer, which is a rather contradictory term. The devitalized skin or muscle is often found in the discharge from such an ulcer, as shreds and tags of tissue. When the granulations are exuberant and project like excrescences be- yond the level of the skin, the ulcer is called a fungous ulcer. The callous or indolent ulcer is deeply excavated, has indurated whitish and undermined or inverted borders, is surrounded by thickened and con- gested skin of a bluish color, shows imperfectly-formed pale granulations covered with a foul-smelling thin pus, and is usually insensible to painful contact. Such ulcers are of long duration, and may well be termed chronic. Ulcers may be complicated or may depend upon the existence of varicose veins, impeded circulation, diseased bone, or may be the seat of FIG. 2. hemorrhage or of malignant processes. sº- —r—i. Other circumstances may contribute ºr * to the production of complicated or unhealthy ulcers, but it is not neces- sary to give a distinctive name to each Oſſlé. Ulcers, otherwise healthy, are often the seat of a purulent discharge, be- cause of pyogenic germs having been allowed to come into contact with the y ulcers' surfaces. Such a suppurating - ulcer is usually denominated a healthy §§ * ulcer, though the term is not strictly applicable. TREATMENT.-The criterion in the treatment of all ulcers is the condition Method of cutting skin-grafts by of the edges. If the borders are pink- means of needle and scalpel. ish and smooth, and gradually slope down to florid granulations, or perhaps are separated from them by a narrow line of bluish-white epithelial cicatricial tissue, it is certain that the ulcer is in a healthy state, and only requires protection from irritation. Hence, it may be dressed with any bland non-irritant application. Car- bolized ointment of the oxide of zinc is, in my opinion, one of the best, if the ordinary aseptic protective silk, or rubber, and gauze dressing is not used. Cicatrization usually takes place from the edges toward the centre, and therefore in large ulcers, even when healthy, the action of the cutaneous cells at the margins may be insufficient to complete the process, or if able to do so, may be very slow in causing healing of the entire ulcerated sur- face. Centres of cicatrization may be established upon the ulcer at any number of points by applying aseptic grafts of skin (Fig. 3). Skin-grafting is best performed by thrusting the point of an aseptic ordinary sewing-needle under the epidermis of the inner surface of the arm or thigh, previously made aseptic, and, after putting the skin on the stretch by raising the needle, cutting out a minute portion of the true skin, with a sharp scalpel or scissors. The graft taken in this almost painless and bloodless manner is then to be gently pressed upon the healthy granulations with its epidermic surface upward and a gauze dress- ing applied. Any number may be engrafted. The grafts at first shed their cuticle and become almost invisible, but in a few days bluish-white M g & ë & à 3% * 2% N 58 SU P. P. U R A TI ON . spots of cicatricial tissue are seen at the points where some grafts have taken root. These islands grow eccentrically by epithelial cell prolifera- tion, and stimulate the periphery of the ulcer to similar activity, so that the cicatrizing process is greatly expedited by the new points of cutifica- tion, which gradually coalesce with one another and with the marginal skin. The process is not attended with much success unless the ulcer be healthy. Long and thin shavings of skin cut from the patient by means of a sharp razor may be used in a similar way. This method causes much more rapid healing, but the pain is rather severe when the shavings are cut. Skin may be taken from a living frog's abdomen and laid upon the ulcer. Plastic operations may be performed to hasten the healing of intractable ulcers by the transfer of healthy integument to their surfaces. ºr g 3. ; : * J. ſ: 3. § yº. % § sy § t Rº º *ś , ºf 3 º *… Skin-grafting in traumatic ulcer of the Scalp. (LEVIS.) The treatment of all unhealthy ulcers must be directed to transforming them into healthy ulcers, and is both constitutional and local. If they depend upon syphilis specific remedies, such as mercury, iodoform, and the iodides, must be given internally; if the tuberculous diathesis exist, iodine and its derivatives, cod-liver oil and tonics, are required. In all cases digestive and other constitutional vices must be investigated and treated. Any local exciting cause, such as bone disease and varicose veins, must be removed, or at least palliated, after which local treatment is to be regulated by the condition of the ulcer. An ulcer accompanied by acute inflammation must be managed on the principles already laid down in the treatment of acute inflammation. Antiphlogistic internal remedies are demanded, while elevation and rest of the part, Scarification, MO RTIF I CATION, OR G A N G R ENE. 59 lead water and laudanum, warm water dressings, or weak astringent solu- tions are used locally. When the inflammation is severe enough to cause sloughing ulceration, supportive treatment and poultices to hasten separa- tion of the sloughs, or other mild applications are demanded. The local irritability and pain which characterize many ulcers are often greatly les- sened by the application of solid nitrate of silver, or strong solutions of the same (gr. xx to fjj of water). Submitrate of bismuth is an excellent local remedy. A moist antiseptic gauze dressing, covered with oiled silk or rubber tissue to prevent evaporation, is far better than the old-fashioned poultice. It is, in fact, an antiseptic poultice. Fungous ulceration is treated by caustics, such as deliquesced chromic acid, or by the surgeon cutting away the exuberant growth with the knife, or scraping it away with a sharp spoon. Ulcers exhibiting pale, oedematous, semi-transparent granulations require stimulating applications of nitrate of silver and sulphate of copper, in solution or undiluted. Callous or indolent ulcers are the most rebellious to treatment. The hard elevated edges must be softened and depressed, and the accompany- ing venous congestion, shown by the livid skin surrounding the sore, re- moved. My own plan is to apply pure carbolic acid, nitric acid, or some other chemical cauterant, to the insensitive edges and to the foul and semi-devitalized tissue covering the depressed and unhealthy granulations. Then a moist antiseptic dressing is applied for a few days to separate the slough thus produced and to soften the callous borders. Subsequently scarification around and through the ulcer relieves the engorged venous capillaries. The pressure of strips of adhesive plaster properly adjusted, or of an elastic bandage smoothly applied from the distal extremity upward, prevents a repetition of the congestion, and stimulates absorption of deposits and cicatrization of the ulcer. Instead of using the caustic, I frequently get rid of the callous margins by paring them away, and then treat with anti- septic dressings and pressure, or the whole ulcer may be scraped away with a curette and treated as a recent wound. Astringents and disinfecting lotions may be used beneath the elastic bandage. Chronic ulcers of small size may be frequently cured with rapidity by dissecting them out, freeing the surrounding skin from its deeper attachments, and uniting the edges of the wound by sutures. Peroxide of hydrogen is said to render a foul ulcer aseptic by oxidizing the devitalized and putrefying discharges. Tubercular ulcers do well when treated with powdered iodoform. As soon as unhealthy ulcers approach the healthy condition cicatriza- tion begins, and may be hastened by skin-grafting. In order to maintain a healthy state of the sore and prevent occlematous and fungous granula- tions, slightly stimulant lotions of chloral (gr. v . or x to fºj), sulphate of copper (gr. iij-v to fj), sulphate of zinc (gr. v to fj), or nitrate of mercury or submitrate of bismuth in solution, ointment, or powder should be employed. When in a few days or weeks the ulcer gets accus- tomed to the effect of one agent and becomes “inactive,” the dressing must be varied, for a new impression will be beneficial. Mucous ulcers are to be treated like cutaneous sores. MoRTIFICATION, OR GANGRENE. 5 DEFINITION.—Mortification, or local death, is the complete and per- manent cessation of vital functions in a part, and differs from ulceration in the devitalized portion being more extensive. Ulceration is molecular 60 SU PP U R A TI O N. death, while mortification is death of appreciable areas of tissue, that is, of tissue in mass. The two processes are, however, allied, and may co-exist, as in hospital gangrene or sloughing phagedaena, where ulceration is too rapid for disintegration to take place. The dead tissue is called a slough or eschar. Necrosis is often used by pathologists to signify death of animal tissues in mass without reference to the character of the structures, but in surgery, necrosis is usually applied to bone and carti- lage; and mortification, gangrene or sphacelation to soft tissues. CAUSES.–Mortification is due to defective nutritive supply and to destruction of cellular activity. The former condition may be caused by obstruction in the arteries, as from ligation, rupture, embolism, plugging by great numbers of bacteria, or diseased arterial walls; obstruction in the veins, as from tight bandaging; obstruction in the capillaries, as from pressure of tumors, or inflammatory deposits; cardiac weakness, which is merely an accessory cause, decreasing the activity of the circulation; in- flammation, by its intensity inducing permanent arrest of circulation, or by its specific mycotic cause having a special tendency to cause destruc- tion or devitalization of tissue. The causes which induce mortification by destroying the vitality and activity of the cellular elements are: injuries, which disorganize tissue; chemical agents, such as acids and alkalies; the ptomaines of putrefactive or other bacteria acting as irritants; and excessive heat or cold. Morti- fication is often due to a combination of several of the causative influences. Defective innervation has been considered a cause of mortification, but it is probable that it acts only indirectly by diminishing circulatory activity, or by rendering parts less cognizant of the contact of irritating agents. The power of the cells to resist gangrenous causes varies in individuals and in tissues. VARIETIES.–Mortification may be moist or dry, according to the causa- tion and circumstances attending the process. If the parts contain much fluid, as is the case when the mortification is associated with venous obstruction and when evaporation is prevented by the integrity of the cuticle, the process resembles the ordinary putrefaction of animal sub- stances as seen in dead bodies. This is called moist gangrene. The local symptoms are due to the fact that ordinary putrefaction is occurring because putrefactive fungi have gained access to the dead tissue through the skin. If the gangrene is due to slowly progressive arterial obstruc- tion while venous and lymphatic absorption is not decreased, or if rapid evaporation occurs on account of the destruction of the cuticle, the parts become shrivelled and dry, and dry gangrene is said to exist. Acute gan- grene is usually moist, because it dies quickly when full of blood, while chronic mortification is generally dry. Soft and vascular tissues mortify much more rapidly than dense, non-vascular structures, such as tendons and cartilages. The infarctions found after embolism of renal and other arteries, the caseous change that occurs in scrofulous products, and similar pathological conditions, are examples of what has been called coagulation-necrosis, which is a change of protoplasm into a material resembling the fibrin of the blood. With this form of mortification surgical pathology has little COD COI’I). º SYMPTOMS.–The constitutional symptoms of gangrene are almost in- variably asthenic, probably because the blood becomes deteriorated by the admission of septic products derived from the sloughing tissues. MOR TIFICATION, O R G A N G R ENE. 61 The feeble circulation and general nervous depression accompanying a very limited area of mortification are often remarkable. º The local symptoms of moist and dry gangrene differ and must be dis- cussed separately. In the moist variety the parts become green, bluish, or black, lose their normal sensibility and temperature, and become softened and covered with blebs containing reddish-brown fluid. The epidermis is easily rubbed off, leaving a dark, smooth surface. Pressure causes a crackling sound, due to the presence in the tissue of the gases generated by putrefactive decomposition. The gases, which are prin- cipally sulphuretted hydrogen, ammonia, and carbonic acid, cause great local emphysema and puffiness of the parts, and with the other products, such as butyric acid, give the characteristic odor of putrefaction. The red streaks along the course of the vessels in the incipiency of gangrene, and the deep color of the parts during its existence are due to the transuded coloring matter liberated by the destruction of the blood corpuscles.

In dry gangrene the appearance of a small brown or black spot, espe- cially upon the toes, where the affection is most frequently seen, is often the first sign of disease ; though at times cramps, and stinging pain, and feeble local circulation are premonitory symptoms. The discolored point, instead of being brown may be a mottled white, and sometimes a vesicle forms at the beginning of the disease. The darkened area becomes blacker and slowly extends with very few accompanying inflammatory symptoms. The dead tissue is dry, without offensive odor, and gradually becomes shrivelled and hard. The loss of sensibility and the lowered temperature of the dead tissue present in moist gangrene, of course, exist here. This form of mortification is frequently called senile gan- grene, but improperly so, since it may occur from chronic ergotism with- out reference to the patient's age, and because moist gangrene may occur in the aged in similar regions of the body. In all forms of mortification, if the patient survive long enough, the dead tissues are separated by the process of ulceration from those whose vitality resists the destructive influence. The living structures become reddened at the line of junction with the slough, and thus constitute the line of demarcation which indicates the extent to which the devitalizing process has been able to exert its influence. Sometimes a row of vesicles forms along this margin. The line of demarcation soon becomes con- Verted into a groove which is lined by granulations secreting pus. This is practically a linear ulcer, and is called the line of separation, because the ulcerative and granulating processes gradually push off the dead tissues by a species of natural amputation and leave an ulcer to heal by cicatrization. Hemorrhage is prevented by coagulation within the 62 S UP P U R A TION . arteries and fibrinous deposition due to the inflammatory action. The inflammation accompanying mortification often gives rise to great pain, which, of course, is located in the living or partially devitalized struc- tures. This increases the general depression due to septic influences of the gangrenous parts. When mortification occurs in deep structures, the slough is thrown off through fistulous orifices, as occurs in carbuncle, and as is attempted by nature, though often unsuccessfully, in necrosis of bone; or, it may become encapsulated and thus be separated from the surround- ing living structures. The latter mode of separation is seen in infarc- tions of the internal organs, TREATMENT.-The general treatment of all forms of gangrene, to be judicious, should be directed to fulfil two indications: first, to remove the cause and thus arrest the progress of the gangrenous action ; and, secondly, to sustain the patient until separation of sloughs has occurred. Unfortunately, the constitutional cause is often difficult of removal, but an effort should be made to bring the system into that condition which will render the causative factors as inoperative as possible, and limit the mortification. If the peripheral circulation is poor because of a feeble heart and degenerated arteries, remedies such as quinia, iron, opium, digitalis, strychnia, alcohol, etc., should be administered and the patient protected from cold and other depressing influences. When there is a tendency to a sthenic type it is possible that slightly depressing agents may be advantageous, but these are seldom needed and should be used with great caution, since the advent of gangrene is soon followed by nervous and circulatory prostration. During the stage of separation of sloughs the flagging powers of the patient must always be supported by active medication with tonics, stimu- lants, and concentrated nutritious diet. Depressing antiphlogistic reme- dies are never justifiable; and if nervous irritability and pain exist opium in full doses is to be employed. Cleanliness, disinfection, and ventilation are necessary hygienic measures. The local treatment of mortification is very important. If gangrene is threatened on account of the tension produced by rapid and intense inflammatory swelling, it may often be averted by free inci- sions several inches in length through the skin, subcutaneous and fascial structures. This treatment relieves local tension by permitting gaping of the wound and affording a free escape of blood and inflammatory products. Much tissue destruction is thus avoided by removing the obstruction to capillary circulation. Parts prone to slough from deficient circulation should be kept normally warm. When gangrene has occurred disinfectant lotions of carbolic acid of an unirritating strength (1:20 or 30), corrosive sublimate (1:1000 or 3000), chlorinated soda, chloride of zinc (1:50 or 100), or desiccating powders of a disinfectant nature, should be used to destroy the fetor of the parts. These should be com- bined with antiseptic gauze dressings, perhaps made moist and covered with oiled silk or waxed paper, in order to encourage and hasten separa- tion of the devitalized tissues. The sloughs may be removed in pieces with the forceps and scissors after the line of separation has divided the vascular attachments. Tendons and fibrous tissues, as they contain no vessels of importance, may be carefully cut, for in this manner the de- composing masses can be removed somewhat earlier. No special dressing is to be applied to the line of separation. The ulcer left after the slough has been detached is to be dressed with mild applications, such as carbol- ized oxide of zinc ointment, ointment of petroleum and boric acid, or H OS PIT A L G A N G R E N E . 63 antiseptic gauze, as in ordinary ulcers. Cicatrization is to be encour- aged. *When mortification depends on a known local cause, such as Crushing of the parts, or ligation or rupture of the main artery, amputation should be performed, except in cases due to frost-bite or burns above the location of injury, without waiting for the line of demarcation. If the gangrene is due to constitutional causes, such as deficient circulation, or ergotism, or to the presence of an embolus whose location is unknown, the surgeon must wait until the line of separation is well marked before attempting operative interference, since the extent of the gangrenous influence can- not otherwise be estimated. In traumatic cases where gangrene is inevit- able, amputation should be promptly performed. HOSPITAL GANGRENE. Hospital gangrene, or sloughing phagedaena, is a peculiar form of rapidly spreading mortification or gangrenous ulceration, which attacks wounds or injuries where the epidermis is broken, when patients are sub- jected to the foul air of overcrowded hospitals and the wounds infected by certain bacteria. It is exceedingly contagious and infectious, and may at times begin as a vesicle if the parts are not much denuded of cuticle. The ulcer resulting is painful, covered with grayish sloughs, and dis- charges excessively fetid, brownish fluid. The edges of the ulcer, as a rule, are sharply cut. The connective tissue is rapidly invaded, and pro- fuse hemorrhage may occur. The constitutional symptoms, which are secondary, are markedly asthenic. The disease is of local origin, due to wound infection, and must be treated as such. The patient should at Once be removed to uninfected quarters, such as a tent, or pavilion hos- pital, and all the instruments, dressings, and sponges be sterilized or destroyed. The sloughs should be lifted off, if possible, and the entire wound saturated with undiluted nitric acid, bromine, or other powerful cauterant to destroy the septic germs. The caustic must corrode the healthy tissue in order to get beyond the gangrenous influence. The actual cautery is probably valuable in such cases. Tonics, stimulants, and other supportive treatment generally combined with opium are required internally. e Fortunately, the aseptic and antiseptic methods of modern surgery have made hospital gangrene practically unknown. C H A P T E R III. ERYSIPELAS, SAPRAEMIA, SEPTICAEMIA, ETC. IERYSIPELAS. DESCRIPTION.—Erysipelas is an acute febrile affection, usually of a low type, due to some mycotic blood contamination, and accompanied by a rapidly spreading inflammation, which has no tendency to limit itself by the exudation of plastic matter. It is most frequently met in the tegu- mentary structures, but may attack mucous and serous tissues as well. As seen by the surgeon it generally occurs as a complication of wounds, but may arise idiopathically. , Simple or cutaneous erysipelas involves the skin alone, while in the phlegmonous or cellulo-cutaneous variety the sub- cutaneous tissue is also inflamed. If the inflammatory process spreads through the cellular or connective tissue without invading the skin, it is called diffuse cellulitis or cellular erysipelas. It is an infectious and contagious disease, and is particularly liable to attack those debilitated by bad hygienic surroundings or depressed by intemperance or by renal and hepatic affections. The septic germs con- tained in putrefying dead bodies have some occult influence in the induc- tion of erysipelas. It appears to be allied to septicæmia, and also follows bites of venomous reptiles, etc. It is uncertain whether it is due to a special vegetable parasite, or results from the streptococcus, which causes diffuse suppuration. Many believe that suppuration occurring in the course of erysipelas is indicative of a secondary infection with pus fungi. SYMPTOMS.–The constitutional symptoms may be of a sthenic type, but unless the disease is very mild and short in its course, they soon present the characteristics of asthenia. Fevers, rigors, nausea, vomiting, coated tongue, constipation, and perhaps delirium, are the early symptoms, which are not lessened by the appearance of the eruption, and are followed by frequent quick pulse, muttering delirium, dry tongue, sordes and often by diarrhoea, and not very infrequently by death. In the cutaneous and cellulo-cutaneous forms the burning or throbbing pain, the Scarlet, or dusky-red, shining skin, with a distinctly elevated margin, the Oedema- tous or brawny character of the swollen part, the tendency to spread, and the lymphatic glandular involvement, make the diagnosis sufficiently distinctive. Vesicles may form and be succeeded by a brawny desqua- mation. Sometimes in the cellulo-cutaneous variety suppuration or gangrene of the connective tissue occurs; then the skin is apt to become less scarlet in color, and the parts have on palpation an Oedematous or boggy feel. There is no sign of pointing, but incision discloses a diffuse form of abscess in the areolar tissue, and gives escape to shreds of gan- grenous tissue and unhealthy, foul-smelling pus, When erysipelas attacks a wound the pus from it becomes lessened, the granulations degenerate, the union breaks down, and the local symptoms, mentioned above are presented about the wound. Cellular erysipelas, often called diffuse cellulitis, resembles the cellulo-cutaneous variety, but usually arises secondarily to a wound, and presents fewer characteristics of inflammation of the skin. Its evident relationship to erysipelas is SA PR AEM IA, S E PTIC AEM IA, A N D PY A. M.I.A. 65 admitted, but the term cellulitis seems preferable to cellular erysipelas. This variety of erysipelas may attack the areolar tissue in the pelvis and other internal regions if they be opened by a wound. The probability of causing puerperal Septicaemia by inoculation from erysipelatous cases must always be borne in mind by the obstetrician or surgeon. An attack of erysipelas lasts from one to two weeks, and in persons of fair health previously, is usually followed by recovery. The subcutaneous forms have a much more unfavorable prognosis than the cutaneous. TREATMENT.-Preventive measures consist in ventilation and steriliza- tion of instruments and dressings. At first a purge should be given and light diet ordered, but, as a rule, depressing treatment is inapplicable, because the disease soon assumes a low type. Hence ten minims of tinc- ture of iron every two or three hours, combined, perhaps, with two grains of quinia at each dose, is the best treatment. Opiates and stimulants may be demanded. Milk and beef essence, or meat juices, are the best articles of diet. A mixture of one part of laudanum, one part of lead- Water, and two parts of water, a combination of lime-water and sweet oil, or a non-irritating antiseptic lotion or ointment, should be applied locally. If suppuration and gangrene threaten, or if great tension is present, numerous incisions, which will gape widely, should be made aseptically, and be followed by antiseptic gauze dressings. When pus burrows, as in the subcutaneous forms of the disease, the cavities should be injected with carbolized water (1 : 40), or solution of corrosive subli- mate (1:2000), and drainage-tubes inserted and counter-openings made. SAPRAEMIA, SEPTICAEMIA AND PY.EMIA. DEFINITION.—There are four conditions often confused which ought to be distinguished; though it is admitted that a clinical diagnosis is fre- quently impossible. They are: 1. Aseptic wound-fever, arising in connection with aseptic wounds, and due, probably, largely to poisoning by the so-called fibrin ferment. This is given off during the disintegration of leucocytes which occurs in inflammation at the time the exudate coagulates. The inflammatory fever usually seen is, however, one of the forms of septic poisoning mentioned below, and is due to imperfect asepsis. If the wound is absolutely aseptic the wound-fever is always inconsiderable. 2. Sapraemia, putrid poisoning, or septic intoxication, which is a febrile condition, due to the chemical products or ptomaines developed by putre- faction of animal tissues, either in the wound or entirely away from the body of the patient. This poison may gain access to the blood by its devel- opment and retention in insufficiently drained putrescent wounds; or, it may be obtained experimentally and be injected hypodermatically. The poison is the result of mycotic action, of course, for putrefaction is due to fungi of putrefaction. The symptoms of sapraemia occur immediately after inoculation, but it requires a comparatively large dose to produce a toxic effect. * 3 Septicºnia, or septic infection, a fever due to infection by putrefac- tive microörganisms which enter the blood by the mucous membranes or by a wound, usually by the latter, and do not produce symptoms until they have had time to multiply. The clinical symptoms are similar to those of Sapraemia, but a most minute dose is sufficient to lead to violent 5 66 SA PRAS MIA, SEPTIC A. M IA, AN D PYA M I A. symptoms. The condition formerly called hectic fever corresponds with what is now called sapraemia and septicaemia. 4. Pygemia, a condition in which the general febrile disturbance, similar to septicaemia, is due to pyogenic germs, and in which secondary foci of inflammation or suppuration, called metastatic abscesses, are formed in the lungs, liver, and other organs. These abscesses in distant organs are due to the transportation in the blood-stream of emboli infected with pus- causing bacteria. Pyaemia is probably simply a multiple suppurative inflammation. The old theory that pyaemia is a condition in which the blood contains pus is untenable, though the derivation of the word pyaemia still suggests it. The relations of sapraemia, septicæmia, and pyaemia are not perfectly understood. They may, therefore, be considered together, at least until their clinical relations and pathology are further investigated. Some authors believe pyaemia to be identical with what I have called septi- caemia, except that the poisoning is more intense. PATHOLOGY..—The peculiar poison, which by introduction into the blood causes sapraemic conditions, is associated with putrid decomposition of albuminous fluids, and is connected with the production of ptomaines by the bacteria causing the putrefactive process. Septicæmia and pyaemia are due to infection by microörganisms themselves; the former by the microörganisms of putrefaction, the latter by the microörganisms of sup- puration. It is usually necessary that there exist some abnormal state of the tissues, such as inflammation, before the presence of such microbes can induce these conditions. The occurrence of septicæmia and pyaemia is promoted by such conditions as favor the contact of wound surfaces with particles of decomposing animal tissue, or of dust containing pyo- genic bacteria, such as necessarily circulate in ill-ventilated apartments containing numerous surgical patients. Septic and infective substances thus introduced into animal fluids encourage therein putrefactive changes and the generation of infecting organisms. It is necessary, however, in order to infect the system, that the poisonous principle be absorbed. A recent wound, or one covered with unhealthy granulations, allows rapid absorption of the poisonous substances, while healthy granulations seem to act as a barrier to septic infection. The blood in septicæmic con- ditions is less coagulable than in health, and the red corpuscles show a tendency to congregate in irregular masses, and to undergo ante-mortem disintegration. In addition, congestions of organs and Stasis of the blood-current are frequently observed. The autopsy frequently shows softening and degeneration of viscera, ecchymosis and even inflamma- tion of the serous membranes, and changes in the glands and mucous membrane of the intestines. Pyaemia may be provisionally considered as septicæmia with the addi- tion of disseminated spots of inflammation and suppuration. These con- sist of metastatic abscesses in lungs, liver, spleen, and other viscera, due to embolism and bacterial infection, and suppuration in joint cavities or inflammation of cellular and serous tissues, caused either by embolism or the blood-change. Metastatic abscesses commence as small, reddish, and usually pyramidal sections of solidified tissue, which are found most fre- quently near the periphery of the lungs, liver and spleen. These soon break down into pus, producing abscesses, which are always small, and which are surrounded by indurated tissue. These multiple or metastatic abscesses result from the process of embolism as follows: At the seat of the original inflammation coagulation takes place in the vessels, and on SAP RAE MIA, SEPTICAE MIA, AND PY A. M.I.A. 67 account of puriform softening of these clots or thrombi, due to septic in- fluences, small particles of the thrombi, are washed into the circulation, carrying along with them pyogenic bacteria. These emboli lodge in the capillaries of the lungs or other viscera, cause impairment of circulation, and by their mycotic nature give rise to numncous suppurative points called metastatic or embolic abscesses.

(BILLRoTH.) Pyaemia is probably not an actual disease, but simply a transference of suppuration by means of emboli and their accompanying pus-causing germs. It is a complication, or variety, then, of suppurative inflamma- tion, due perhaps to putrefactive germs having caused softening of the thrombi. Hence the frequent association of Septicaemic conditions and pyaemia. CAUSEs.-The exciting cause of septicæmia is the peculiar poison already described as usually generated by the mycotic decomposition of albuminous fluids. The poison, under the name of sepsin, is believed to have been isolated; but our knowledge of the nature of the agency inducing septicaemic conditions is very limited. Any condition which tends to produce septic material in the patient's body may be called a predisposing cause. The most frequent of all is the existence of a wound, though it is possible that septicæmia may result from septic changes in the fluids of the body, due to agencies introduced by absorption through the mucous membranes. Hemorrhage, protracted shock, erysipelas, osteo- myelitis, puerperal lesions, overcrowding of patients affected with suppu- rative diseases, and bad hygienic surroundings are important predisposing Causative factors. %– 68 SAP RAE MIA, SEPTIC A. M.I.A., AND PY A. M.I.A. SYMPTOMS.—The first symptom of septicæmia or of pyaenia is often a sudden rigor preceded or accompanied by a rise in temperature, which is followed by exhaustive sweating with rapid lowering of bodily ten- perature. These phenomena resemble those of malarial fevers, but the hot stage between the rigor and the sweating is less marked. The tem- perature during the chill may rise to 104°-107°, and during the sweating period may fall, though rarely, to normal or below. The rigors and great temperature changes are repeated at more or less irregular inter- vals. The pulse is increased in frequency, but diminished in force, beat- ing 90–120 per minute; and respiration is similarly affected, being more frequent and less deep. The breath and emanations from the body have a sweetish odor which is of some diagnostic value in septicaemic states. The tongue is usually furred, while nausea, vomiting, and diarrhoea are frequently present. The skin, which has a pale or yellowish hue, due to pigment from disorganized corpuscles, may present Sudamina, and even an ecchymotic or a pustular eruption. Albuminuria is not infrequent and delirium is common. As the disease progresses the symptoms assume the asthenic or typhoid character as shown by rapid emaciation, great exhaustion, twitching of the tendons, drowsiness, low muttering delirium or coma, dry and brown tongue, sordes upon the teeth, colliquative diarrhoea and sweating. The wound during this time usually, but not always, assumes an unhealthy character of granulations and discharge. In most cases the discharge of pus decreases, and it may entirely disap- pear. About the sixth or tenth day, if pyaemia and not mere septicæmia exist, the formation of metastatic abscesses and the occurrence of other inflammatory foci give rise to jaundice, cough, pain which is often intense in the joints, and suppurative or inflammatory signs in the viscera and elsewhere. The lobular pneumonia, hepatitis, pleuritis, pericarditis and other in- flammations that at times occur, give rise to their characteristic symptoms. The prognosis is always unfavorable, as in acute cases death takes place, as a rule, in from one to two weeks, and in chronic cases in from one to two months. Recovery, however, does at times occur after a protracted convalescence. It is often impossible to discriminate between cases of septicæmia and pyaemia until the autopsy proves or disproves the existence of metastatic abscesses. The symptoms have, therefore, been grouped together as representing conditions which are often indistinguishable during life. DIAGNOSIS.–Septicæmia or pyaemia may be confounded with malarial or typhoid fever. The suddenness and intensity of the rigor and of the temperature rise, the irregular occurrence of these phenomena, the great fall in temperature, which seldom reaches the normal before the occurrence of another rise, the profuse Sweating which follows the rigor without the intervention of a marked hot stage, and the association of these symptoms in many instances with a wound, usually serve to render a differential diagnosis possible. Quinine will usually modify malarial conditions but not septic ones. Ordinary inflammatory fever differs from septicæmia because it usually ceases when suppuration begins. Rheum- atism is at times distinguished with difficulty from chronic pyaemia, but the acute forms of the diseases differ, because rheumatic effusion into the joint cavities is seldom purulent as in pygemic synovitis. Again, the sour odor of acute rheumatism is replaced by the sweetish smell often noticed about septicæmic cases. The rapidity of emaciation and the fatal issue SA PR AEM IA, SEPTIC A. M IA, A N D PY AEM IA. 69 in the majority of cases of septicæmia or pyaemia, as well as the evident existence of secondary inflammations and metastatic deposits in the latter disease, proclaim the nature of the affection with no doubtful voice. It is, however, difficult at times to certify that visceral symptoms are really due to metastatic abscesses, and not to simple inflammatory lesions. Many of the symptoms of typhoid fever resemble those of septicæmia, because the intestinal lesions of the former disease lead to septic infection of the patient, TREATMENT.-The indications of treatment are to remove the exciting causes of Septic conditions by general local prophylactic measures, and to support the system until the poison is eliminated. An abundance of fresh air, sequestration of pyaemic, erysipelatous and similar patients, sterilization of clothing and instruments that possibly contain Septic germs, and the aseptic or antiseptic treatment of all wounds, are im- portant factors in preventing the occurrence of the disease in hospitals. These are general measures to preclude the advent of the disease among patients with operative or accidental wounds who are to be subjected to the influences of hospital wards. It is especially necessary, moreover, so to treat every patient that he may not be liable to self-infection from generation of the septic poison in the discharges of his own wound. Hence, union by first intention, or by rapid and healthy granulation, is to be obtained as quickly as possible. The surgeon must be on his guard, however, lest in this endeavor he allow purulent accumulations and burrowing to occur; for pus contained in irregular cavities exposed to the air soon decomposes, and putridity is the fertile source of septic infection. Hence, free incisions, counter-openings, and perfect drainage of the lowest depths of the wound, with copious antiseptic affusions, are absolutely essential. Free laying open of irregular, lacerated, and dirty wounds, even before suppuration occurs, especially if serous cavities be involved, is often the most scientific treatment, although, to the inex- perienced mind, it seems like protracting the cure by increasing the wound surfaces. Such wounds should be thoroughly washed out with Sublimate solution (1 : 500 to 1 : 5000), carbolized water (1:40), solu- tions of chloride of zinc (1:100 or 1 : 50), or some similar antiseptic lotion, before suturing or dressing. In very large wounds corrosive sub- limate may cause toxic symptoms if used in strong solution. Shreds of devitilized tissue, decomposing blood-clots, and unhealthy pus confined in any portion of such wound will cause septic or pyaemic symptoms with great readiness. All abscesses forming in the neighborhood of the original wound must be opened promptly. The method of dressing Wounds must be that known as the aseptic or antiseptic method, of which there are many variations fulfilling the same conditions. Mopping the surface with undiluted carbolic acid may, perhaps, become an im- portant preventive agent in certain cases, where infection is feared, as it probably seals the vessels and hinders septic absorption. To support the system after septic infection has occurred, tonics, stimu- lants, and nutritious food must be employed. There is no specific remedy available. At first a laxative may or may not be required. The appear- ance of the tongue and state of the bowels indicate or contra-indicate its use. Quinia (gr. j) and tincture of chloride of iron (m. xx) every . three or four hours; brandy in amounts varying from two to six fluid- ounces daily, and opium, if pain demands it, in one or two-grain doses every second or fourth hour, will be the line of medication suited to the majority of cases. Frequent administration of cream, milk, and animal 70 S A P R AE MIA - S E PTIC AE M IA, A N D PY AE MIA . 5 ) broths, given in small amounts, day and night, is absolutely essential. An astringent combined with opium (as for example, tannic acid gr. j, opium gr. j, capsicum gr. 3); atropia Sulphate gr. Tº ; turpentine m, X, or some other remedy, may be needed at varying intervals, to combat diarrhoea, profuse sweating, or dry tongue and tympanites. In fact, symptoms must be met by appropriate remedies, since no specific to eliminate the poison is of recognized value, though many have been advocated. O H. A. P. T. E. R. I. V. SCROFULA AND TUBERCULOS [S. DEFINITION.—Scrofula, or struma, was formerly believed to be a consti- tutional condition in which there existed an abnormal tendency to inflam- mations of unusual chronicity, and in which the inflammatory products were not readily absorbed, but infiltrated the tissues and underwent cheesy degeneration. These inflammations occurred either idiopathically or after slight injuries, and were especially prone to attack the lymphatic glands, the skin and mucous membranes, the serous membranes, and the bones and joints. We now know that scrofula is simply tuberculosis, usually of the infil- trated and not of the modular form ; and that it is due to the bacillus tuberculosis. The structures mentioned above are obviously those into which the parasitic plant most readily penetrates. Microscopical exami- nation of scrofulous lesions shows the presence of typical tubercles and the bacillus. It is a well-known clinical fact that miliary tubercles may result from scrofulous lesions. Lupus, also, is probably simply an example of cutaneous tuberculosis. It is thus seen that these three conditions, which formerly were considered separate diseases, are now, according to recent pathological research, included in one category. Tuberculosis is an infective disease due to a bacillus. Its lesions may be so numerous as to justify the term general tuberculosis, or there may be a single lesion, when it is known as local tuberculosis. The original infection, of course, is usually a single lesion, but it is often the focus from which further infection originates, causing lesions in distant parts of the body. Chronic inflammation due to the bacillus tuberculosis may give rise to small nodular masses, or may assume the infiltrating form. The inflam- matory lesions due to the antagonism of the tissue to the microbic irrita- tion, are small masses of granulation tissue called tubercles, because they usually make small shot-like protuberances. Tubercles are de- scribed from their color as gray and yellow ; the latter, however, are simply a later stage of the former, because the gray tubercles usually finally undergo cheesy degeneration. Tubercles are found in the skin, the subcutaneous tissues, the mucous membranes, the serous membranes, the cancellated structure of bones, the lymphatic glands, the lungs, the liver and testicles; in fact, in al- most every structure, though most frequently in those just mentioned. PATHOLOGY..—Gray or miliary tubercles are, according to my concep- tion of prevalent pathological views, minute inflammatory shot-like tumors or growths, not larger than a millet-seed, consisting of granulation tissue and resulting from infection of the system by the bacillus tuber- culosis. The general infection occurs through the blood and lymph- atic currents, and is due to the transfer of the organisms from some local tubercular inflammation which may have remained many months Without infecting the rest of the body. The gray tubercles undergo 72 S C R O F U L A A NI) TU B E R C U L OSIS. cheesy degeneration, as, indeed, may any structures which have little vas- cularity and great abundance of cells, and become yellow tubercles. Miliary tubercles may not only be Fig. 7. due to some previously existing caseous tubercular centre, but be- come caseous themselves. The term yellow tubercle is often applied to cheesy masses, without much refer- ence to their causation. Gray tuber- cles show microscopically a network of large, branched, many-nucleated cells, called giant-cells, associated with a small-celled structure resem- bling adenoid tissue. Differences occur, however, with variation in lo- cality of the tuberculous lesions. Tubercle bacilli in giant-cell. Specimen The bacilli al"e found within the tu- from tuberculosis in a horse. (GREEN.) bercle, and especially in the giant- cells. Persons who may have an inherited proneness to inflammatory affections, characterized by chronicity and by products containing many cells and tending to caseation, would be most liable to afford a suitable soil for the tubercle bacillus, and thus become tuberculous. They are those who were formerly called scrofu- lous or strumous. Cheesy or calcareous degeneration, encapsulation of the bacilli by fibroid or scar tissue, and breaking down into puriform fluid, causing the so called chronic abscess, may occur as secondary changes. CAUSEs.-It was formerly taught that the tendency to such inflamma- tions was often inherited, constituting hereditary scrofula, but that a chronic inflammation might cause infection and tuberculosis in one who had not previously shown any caseous degenerative changes, and who had no inherited predisposition thereto. This was denominated acquired scrofula. A chief cause of inherited scrofula was thought to be syphilitic ancestry, which established the tendency to chronic and cellular forms of inflammation. The acquired tendency to scrofulous affections was at- tributed to improper nutrition, often, perhaps, due to feeding infants on the milk of tuberculous cows, to impure air, exposure, and overwork. We now know that it is infection by a vegetable parasite which causes these anomalies, and that the fungus produces its effects most surely when it finds a suitable soil for its germination. Such a soil is furnished by the ill-nourished, the weak, whose tissues prove least resistant to my- cotic invasion. Scrofula and tuberculosis exist much more frequently among children and young adults, but no age is exempt from such affections. SYMPTOMs.-The affections which are apt to occur among those called tuberculous are characterized by protracted inflammation and degenera- tion of the tissue, often giving rise to a puriform liquid. The products of this chronic inflammation, instead of being rapidly absorbed, accumulate and often become cheesy. Enlarged lymphatic glands, which may de- generate into caseous masses, or soften and give rise to thin curdy puri- form fluid, are frequent. Other lesions are chronic catarrh of the various mucous membranes; cold abscesses which burrow, and, discharging, leave ulcers with livid, ragged edges, that in turn are followed by irregular and puckered cicatrices; phthisis, synovitis, and arthritis; caries and necrosis; corneitis; and ulcers and cutaneous inflammations, often called scrofulides. S C R OF U L A A N D TU B E R C U L O S I S. 73 Attempts to define the physical and mental characteristics of those liable to suffer from strumous disease are valueless, because all temperaments may, as we now know, become tuberculous from infection with the bacillus tuberculosis. TREATMENT.-Inherited predispositions to tubercular infection must be so treated as to prevent the possibility of infection ; when infection has occurred the original lesion must be so managed as to obviate general infection. The best possible condition of nutrition must be obtained by good diet, warm clothing, and out-of-door life in equable climates, com- bined with bathing and friction of the skin. The digestion must be care- fully watched, and regulated by alkalies, laxatives, mineral acids, tonics, and proper exercise. Each case demands especial study. Cod-liver oil, syrup of iodide of iron, quinia, iodide of potassium, iodoform, iodine, arsenic, mercury, chlorate of potassium, and rarely alcohol, are the medi- cinal agents usually required, but they are secondary to the hygienic measures mentioned. To hasten the cure of the chronic inflammations, local measures, such as recommended under that heading, are required. Early and complete excision of the tubercular lesion is often the safest course. The pus of abscesses is sometimes absorbed, but it is better to evacuate it with a knife or aspirator than to have the deformed cicatrix due to spontaneous evacuation. Glandular masses, if small, may be enucleated. To avert an impending scrofulous or tuberculous general infection, excision of bone, arthrectomy of a joint, or even amputation of a limb, may be necessary. Such operations, however, must not be done too hastily, though in certain cases their expediency is unquestioned as a factor in preventing or ameliorating an acquired tubercular habit. The deformity due to irregular cicatrices after abscess of cervical glands may be relieved by dissecting out the elevated masses, and by sliding skin over the depressed scars so as to make a level surface with a single white linear SCall". C H A P T E R V . SYPHILIS. DEFINITION.—Syphilis is a constitutional disease resulting from a blood poison, of unknown nature, introduced by inoculation or by heredi- tary transmission. The acquired form has a period of incubation, and appears to be self-protective—that is, a person who has once been inocu- lated is not liable to be affected by subsequent exposure to the virus. The words venereal disease are often used to include syphilis, chancroid dis- ease (improperly called local syphilis), and urethritis. The term should be rejected because these affections are by no means always acquired through sexual intercourse, and are so mutually distinct that any classi- fication of them under one heading induces mistaken ideas of pathology. While discussing syphilis and its primary lesion, hard chancre, I shall speak incidentally of chancroid disease, or soft chancre, which is a dis- tinct affection, resembling the first manifestation of syphilis, but not resulting from constitutional infection. This disease, as well as urethritis, or gonorrhoea, will be fully considered under local diseases of the genito- urinary apparatus, where they properly belong; though chancroid is by some described in this connection because of its important differential diagnosis from syphilis. CAUSES.–Syphilis, when not congenital, can only be produced in healthy individuals by inoculation with the specific virus. Inoculation may occur directly, from contact usually, of an abraded surface, with the secretions of primary or secondary manifestations of the disease situated upon another person, or indirectly by the discharges of such lesions being transferred by means of drinking-cups, surgical or dental instruments, tobacco-pipes, towels, etc. In the vast majority of cases of acquired syphilis, inoculation occurs during sexual intercourse, from chancres or mucous patches upon the genitals. Inoculation may occur from the blood of syphilitics, taken during the eruptive period of the disease, being introduced into the system by vaccination, skin-grafting, and, perhaps, also by contact with the menstrual blood of women infected with consti- tutional syphilis, who have at the time of coitus no lesion of the genital organs. It is doubtful whether the saliva, milk, and semen can cause syphilis, unless mixed with the discharges and blood coming from mucous patches or other lesions. The discharge from tertiary ulcers or gummy tumors is not capable of inoculating other persons. It is not absolutely necessary that a break or abrasion of the skin or mucous membrane exist to permit admission of the virus. A woman, previously healthy, may, it is said, become infected from carrying a foetus which is syphilitic from the semen being furnished by a syphilitic father. The woman, if this is true, is infected by the man, not directly, but secondarily through the medium of the foetus and the placenta. A prolific cause of syphilis is heredity. Two syphilitic parents are almost certain to have, if repeated abortions do not interfere, children who subsequently exhibit symptoms of constitutional syphilis. If only SY M P T O M S. 75 one parent is syphilitic the child is less liable to infection, particularly if the diseased parent is the father. Hence marriage of syphilized subjects is to be discouraged ; though if the acquired disease was mild and well treated and no lesions have appeared for one or two years, the risk of con- taminating the wife or husband and of producing children with syphilitic constitutions is reduced to a minimum. Scrofulous or tuberculous chil- dren are frequent witnesses of such marriages which have not in truth produced true hereditary syphilis; but have brought forth a posterity liable to chronic inflammations, caseation, and tubercle infection. The cause of syphilis is almost certainly a microörganism, though up to this time it has not been definitely and certainly found. CLINICAL HISTORY..—A study of the symptoms of syphilis reveals the existence of: 1. A stage of incubation lasting two or three weeks, followed by 2. A primary stage, marked by chancre and bubo, which, at the end of two or three months, is followed by 3. A secondary stage, characterized by eruptions and inflammations of the mucous membranes, which, at the end of six or twelve months or a longer period, is succeeded by 4. A tertiary stage, exhibiting itself by ulcers and other severe cuta- neous lesions, bone diseases and gummy deposits, and which often is fol- lowed, if the patient marries, by what may be called 5. A quarternary stage, exhibited in his children. The quarternary form, or hereditary syphilis, presents lesions similar to the secondary and tertiary stages of acquired syphilis. SYMPTOMS.–The stage of incubation is the period between the time of contact with the virus and the appearance of chancre. It waries greatly, but lasts, on the average, two or three weeks. It often is represented by the patient to be longer than this, because he fails to recognize the advent of a small chancre. During any portion of the incubation period local inflammation of the parts may arise, due to simultaneous contact with irritating discharges (chancroid, etc.), or to injury, which has no pathological relation to the syphilitic chancre that is subsequently developed. The local disease may persist even after the stage of incubation has passed and the initial lesion (chancre) is exhibited. If the syphilitic inoculation was effected at the same point at which the inflammatory ulceration, due to irritating discharges, is in progress, the patient will have the two lesions combined at that locality. This fact has induced many observers to believe erroneously that chancroid may be followed by syphilis. Primary stage.—The initial lesion of acquired syphilis is always chancre, which is soon followed by lymphatic involvement, causing adenitis. The inflamed and enlarged glands constitute a swelling or tumor, called bubo. It must be remembered that when chancre appears the patient has already been syphilitic for two or three weeks; that is, during the time of the incubation stage, The chancre is the result of his syphilitic condition, and is not a local sore, which generates the poison that infects the system. The chancre, which must not be confounded with the chancroid sore (chancroid, soft chancre, non-infecting chancre), presents different appear- ances, according to its situation and the depth of the tissue involvement. Very frequently it is a small, superficial papule, having a reddish color and a circularly or eliptically ulcerated apex. Sometimes there is no ulcer whatever, but it is rare that some ulceration does not appear. It is 76 SY PEIIL I S. probable that the ulceration is usually due to infection of the surface of the syphilitic lesion by pus bacteria. Abrasion, perhaps, removes the epi- dermis from the papule, and pyogenic organisms infect the part so that suppuration and ulceration occur. When the ulcer exists it is not much excavated, and secretes a serous fluid, containing epithelial and other particles, but no pus, unless active inflammatory processes have been developed by irritation. The papule, with or without ulceration, has at its base a thin layer of hardened tissue, which is sharply defined, and resembles to the touch a disk of cartilage or parchment, buried under the skin. This induration is less apparent when the chancre is located on a mucous than when on a cutaneous surface, and in some cases does not per- sist long. At other times the chancre is a deep ulcer, with elevated edges and a surface covered with a sloughing material; still the discharge is not purulent, but watery and, perhaps, slightly sanguinalent. The indu- ration is deep and slightly outlined, and gives the sensation of a split pea between the finger-tips. This hardening lasts a long time even after the ulcer has been healed; but, finally, when cicatrization and absorption have occurred, there remains a cicatrix with comparatively little depres- sion. The ulceration does not destroy the tissue of the part as much as it appears to do, since it is the newly-formed inflammatory lymph that disin- tegrates. Both these forms are true chancres, but the deep ulcer seems to be due to a more virulent infection, as it appears sooner after inoculation than the superficial chancre, and, as a rule, does not follow inoculation from secondary syphilis, which is more apt to cause superficial chancre, such as described above. Either form of chancre may assume phagedenic action under local irritation, or on account of a depressed state of the system of the patient, such as struma and scurvy. The secretions from these indurated, hard, or infecting chancres, whether superficial or deep, will not produce similar sores when applied to other parts of the patient's body, for he is protected against further syphilitic inoculation. How long this protection lasts is not definitely understood. On this account chancre is single, unless inoculation at several points has occurred at the same time. Coincident with the stage of induration of chancre, enlargement and induration of the nearest lymphatic glands appear, constituting the syphi- litic bubo. These bubos are usually situated in the groin, because the common location of the chancre is upon the genitals. Bubos, however, are found in the axilla, above the internal condyle of the humerus, under the jaw and elsewhere, according to the position of the chancre. If the initial lesion is near the middle line, a bubo will, probably, be found on both sides. If the lymphatic vessels from the inoculated spot lead to internal lymphatic glands, as in uterine chancre, no external bubo will be manifested. Induration of the glands is, probably, always present in syphilis, but cannot occur unless chancre has preceded it. Syphilitic bubo appears, about three weeks after inoculation, as a chain of hardened and enlarged glands, which are painless, or nearly so, and show no tendency to suppuration. The inflammation affects the glands only, and not the surrounding tissue, hence they retain their characteristic almond shape, and do not suppurate unless there be some cause of pyogenic infection, such as co-existing chancroid disease, or an infected wound. Then the Sup- puration is not syphilitic, though, if due to chancroid, the pus may have the contagious properties of that non-syphilitic sore. If it be due to other inflammatory causes, the pus is as innocent as the pus from common acute SY M PTO M. S. 77 abscesses, or ordinary so-called sympathetic suppurating buboes; that is, it contains pus organisms, but not the syphilitic poison. The chronic and indurated bubo of syphilis may continue for many months after the chancre has disappeared. The clinical history of true syphilitic bubo is very different, as will hereafter be seen, from that of bubo following chancroid disease. . Secondary stage.—About six weeks after the appearance of the chancre, the patient becomes more or less feverish, has, perhaps, headache and general uneasiness of an indefinite character, and then discovers, in the course of five or six days, the existence of an eruption, Sore-throat, mucous patches, cervical adenitis, falling of the hair, or iritis. These are the symptoms of the Secondary stage, which usually occurs at the time men- tioned, and is preceded by the prodromes described. It may be delayed until the sixth month, and often overlaps the period of primary syphilis, which is prolonged by imperfect resolution of the chancre and bubo. The cutaneous lesions of syphilis are called syphilides or syphiloderms, whether occurring as symptoms of the secondary or tertiary stages. In sec- ondary syphilis, the eruption is usually macular or papular in form ; though the scaly, vesicular, pustular and tubercular syphiloderms may occur. The last two varieties are more common in the later periods of secondary syphi- lis, or in the tertiary stage. Syphilitic skin affections usually become some- what brownish in color about the time of their disappearance, are accom- panied by very little itching, often present several varieties at the same time, and are not confined to a single portion of the patient's body. Mucous tubercles or patches are flattened and elongated elevations, a quarter or half an inch in diameter, found on the mucous surfaces, at the muco-cutaneous junctions or where the skin is very delicate, and covered by a whitish exudate. They appear at first as reddish elevations, from which the cuticule is removed, and upon which the exudate soon occurs, giving the surface an appearance similar to that produced by touching mucous membrane with nitrate of silver. The sore mouth and throat of Secondary syphilis are due to these mucous patches, to superficial inflam- mation and ulceration, or to a combination of these lesions. Inoculation of syphilis occurs more frequently from these mucous patches about the genitals and mouth than from the secretions of chancre itself. Inflammation and chronic enlargement of the lymphatic glands, especially of those situated along the posterior margin of the sterno-mastoid muscle, are very frequent symptoms of the secondary stage. These have no necessary relation to the existence of marked cutaneous lesions in the neighborhood. Falling of the hair of the scalp and other regions, and inflammation of the iris are frequently present in secondary syphilis. The papular eruption often occurs as an accompaniment of the iritis. Other Symptoms may present themselves in the secondary stage, but the most Common have been mentioned. Tertiary stage.—There is no distinct separation between the secondary and tertiary stages, but the latter is characterized by more chronic and less contagious lesions, which affect, as a rule, the deeper tissues of the body. It is convenient to consider lesions originating after the lapse of six months as tertiary symptoms. Tertiary symptoms are not exhibited in all cases, because the disease may be so mild or so judiciously treated that it subsides or becomes latent with the disappearance of the secondary troubles. Very often, however, the disease remains in abeyance for many months or years, and then tertiary lesions supervene. The lesions produced by tertiary syphilis may be classified under the 78 SY P H II, I S., following heads: 1, Fibroid degenerations; 2, gummy deposits; 3, changes in the arterial walls. The fibroid indurations occur in limited areas sur- rounded by normal tissue, and are found in periosteum, sheaths of nerves and of organs, and in muscle. Gummy tumors or deposits are yellowish masses of firm consistence, due to degenerated cell-products, surrounded by a fibrous area, which is in turn encircled by a cellular and vascular zone intimately adherent to adjacent structures. They are the most character- istic formation of syphilis and occur in the tegumentary structures, mus- cles, fasciae, bones, and internal organs. They may become caseous, but often in a manner not well understood, cause suppuration around them- selves, break down and cause the deep intractable ulcers of tertiary syphilis. The change in arterial walls occurs in the inner coat and causes diminution in calibre, which interferes with circulation and may induce degenerative changes. The tertiary syphiloderms are usually pustular, tubercular or ulcerous. The ulcerations and suppurations found in syph- ilis are probably the result of the low vitality of the cells, affording a place of least resistance for the harmful localization of pyogenic fungi circulating in the blood-stream. The germs cause suppuration there, when to healthy tissues they would be unable to do injury. The rupial ulcer with its acuminated scab is especially characteristic, as are the deep ulcers due to destructive changes in gummy tumors. Similar lesions of the oral and other mucous membranes are frequent. Periostitis; oste- itis, modes due to lymph or gummy deposits under the periosteum, and all causing bone-pains (osteocopic pains) especially at night; caries and necrosis; iritis, retinitis and choroiditis; falling of the hair; onyxitis; orchitis; cerebral and spinal inflammations; and, in fact, inflammation of any organ or tissue may be induced by constitutional syphilis. Many of these lesions depend on the deposition of gummy material, others are due to the fibroid and arterial changes mentioned. FIG. 8.

Quarternary stage.—This seems to me a good name to apply to heredi- tary syphilis, though I admit that syphilitic children may be born to parents who have not yet advanced beyond the secondary stage. It is unnecessary to discuss the method Notched teeth of hereditary syphilis. Boy, ten years, who had periostitis of tibia. Lower teeth show normal sex rations of second dentition, and are elongated, probably because the imperſect upper teeth do not oppose them. by which children inherit the syphi- litic cachexia, but it is recognized that the disease is more certainly derived from a syphilitic mother than from a syphilitic father, and from two more certainly than from one syphilitic parent. The child may not present any distinctive symptoms until a few weeks after birth, when its unhealthy looking and shrivelled skin, its aged IDIA G. N. O S I S. 79 appearance, the nasal catarrh and stomatitis due to the inflamed mu- cous membranes, and the possible discovery of cutaneous eruptions or of mucous patches about the anus and genitals will point unequivocally to its syphilitic parentage. The syphilis so exhibited is of the secondary form; and by its ability to inoculate other subjects, and its greater or less protective power against further inoculation of the same subject, it proves its identity with ordinary acquired syphilis. If death does not remove the child, further secondary and tertiary symptoms will in time follow. Interstitial keratitis, periostitis, bone dis- ease, and many tubercular affections will in time be developed. The low cell-vitality of syphilitic children makes easy the assaults of the tubercle bacillus. The resistance of healthy tissues is wanting. The peculiar notched condition of the upper central incisor teeth of the permanent set, first described by Hutchinson, of London, is often seen. These two teeth, and at times others, are poorly developed; having a conical shape and a cutting edge, which is marred by an irregularly bevelled anterior surface, or even distinctly notched by the breaking away of the central portion. This notched condition must not be confounded with the normal serrated edge of newly extruded teeth of healthy chil- dren. The teeth of syphilitic children are often irregularly placed, and look like the end of a screw-driver or are mere pointed pegs. Syphilitic women are liable to abort frequently because of the diseased condition of the placenta, and it is only after the woman has regained a fair degree of health that the foetus is carried until full term. DIAGNOSIS.—The diagnosis of syphilis rests upon the general clinical history of the disease rather than upon any one symptom or upon the statements of the patient. The distinction between chancre and the local affection called chancroid disease is often difficult, and at times impos- sible, unless time be given to watch the progress of the symptoms. The diagnosis is to be founded upon the following characteristics: Chancre. Time.—No noticeable lesion until two or three weeks after exposure. Number.—Single unless several points in- oculated at time of exposure. Character.—Papule, superficial abrasion, or an elevated ulcer, with edges sloping towards center, which coalesces with ad- jacent tissue and discharges a scanty, serous, non-purulent fluid. Permanent, indolent, non-inflammatory induration at base of sore, feeling like a disk of parchment or a split pea beneath the integument. No tendency to phage- daema. Heals spontaneously. Bubo.—Always present, involves a chain of glands, is indurated, usually bilateral, and seldom suppurates. If it does sup- purate pus is not inoculable. JPalhological mature.—Due to a constitu- tional disease, which is soon manifested by other symptoms. Protects the patient from subsequent inoculation; hence, Surgeon cannot produce another chancre on him by inoculation with the dis- charge from the suspicious sore. Chancroid. Irritation early and sore developed within a week after exposure. Multiple, because pus is auto-inoculable and produces other ulcers. Ulcer, with edges steep as iſ a piece of tissue had been punched out or ragged and irregular; does not coalesce with ad- jacent tissue and is covered with a drab- colored deposit. The secretion is puru- lent, very copious, and inoculates sur- rounding surfaces, thus producing mul- tiple chancroids. No induration. Liable to phagedaema. No tendency to heal. Often absent, involves but one gland and one side Very prome to suppuration, furnishing pus which readily inoculates and produces other chamcroid ulcers. The suppurating bubo is practically a chancroid. A local affection never followed by consti- tutional symptoms and, therefore, does not protect against Subsequent inocula- tion ; hence, surgeon can produce many other chancroids by inoculating patient with pus from original sore. This table gives the usual clinical history of the two affections, but it must be remembered that the time of appearance and the physical char- 80 SY PH I L I S. acteristics may vary somewhat. Thus, a chancre may be so infected by pus fungi as to furnish a purulent secretion; and a chancroid may have a slightly indurated base by reason of repeated applications of caustics. Chancre is to be distinguished from epithelioma by the earlier glandular involvement it causes, the effect of anti-syphilitic treatment, and the con- comitant constitutional symptoms. Many doubtful cases of cancer and of chaneroid can be diagnosticated by the collateral evidence obtained from confrontation of the patient and the person by whom he is supposed to have been inoculated. Secondary and tertiary syphilitic lesions are to be differentiated from non-specific affections by the history, the co-existence of multiple patho- logical changes, the exclusion of other causative factors and the response to anti-syphilitic remedies. t TREATMENT.-Syphilis is a constitutional disease and demands general treatment. Cauterization or excision of the chancre is valueless, since constitutional symptoms are not the result of the chancre, but the latter is a lesion due to general infection dating from the time of inoculation. Hence, the local treatment of chancre should consist of measures that prevent the irritation of the ulcer, such as is caused by rubbing against the clothing and infection with pyogenic microbes. Antiseptic protection of the primary induration before the epithelium is abraded is eminently proper. Cleansing with soap and water and a dry dressing of sublimate gauze, so applied as to permit urination, is judicious treatment. Iodo- form dissolved in collodion (gr. X to faj) is a convenient application, as it makes an impervious coating. It should not be applied until the sore is made aseptic by washing with soap or sublimate solution. If the chancre becomes phagedaemic, which is rarely the case, strong caustics, such as undiluted nitric or carbolic acid or nitrate of mercury, may be employed to arrest the destructive action. The actual cautery destroys the microörganisms better than any of these. It must be applied to every crevice of the sore. Bubo, as a rule, demands no local treatment, for it is painless and merely an expression of the constitutional implication. Moreover local treatment is useless because it, as a rule, effects no result. If suppuration occurs about the indurated glands, the pus should be evacuated as if the abscess were non-specific, which, indeed, it really is. The special constitutional remedies for syphilis in all its stages are mercury and iodine; of these mercury is probably the more important and efficient. The manner of using these drugs is important, but the preparation employed may vary with the fancy of the surgeon and the convenience of the patient. It is absolutely essential that the effect of the remedy be maintained for one or two years, if the tendency to sec- ondary and tertiary manifestations is to be eradicated. Mercury is the better remedy for the primary and secondary lesions, and iodine probably the better one for the tertiary affections; though this dictum may at times be invalidated by individual experience. In the later lesions I usually employ a combination of both drugs. As soon as the diagnosis of syphilis is established, mercurial treatment is to be instituted, and, even in doubtful cases, I should probably give the patient anti-syphilitic remedies. Many, perhaps most, syphilographers prefer to wait until the diagnosis of a doubtful sore is absolutely estab- lished by the occurrence of secondary symptoms. The green iodide of mercury (often called the protiodide) may be given in quarter-grain pills three times daily after meals; or a corresponding amount of blue pill or calomel may be substituted. If it is found in the course of a few days T. R. E. A. T M E N T. 81 that unusual looseness of the bowels is produced, one or two grains of tannic acid or a sixth of a grain of opium may be added to each pill. This amount of mercury will probably be tolerated for several weeks without causing tenderness of the gums or undue salivary excitation. As soon as either of these effects is induced the amount must be decreased or the drug entirely suspended for a week. In cases where the disease is violent in its first manifestations, an early decided mercurial impression is necessary. Blue pill in one to three grains daily, or calomel to the amount of one-half to two grains daily, or a similar amount of green iodide continued until evidences of moderate constitutional effects become evident, is judicious treatment. If no beneficial effect is observed from ordinary small doses, and the condition of the gums will warrant it, the dose must be increased. In this tentative manner the maximum quantity which the patient can take without causing gastric, intestinal, or oral irritability is determined. This he must continue during nearly two years, occasionally omitting treatment for one or two weeks, but never suspending it entirely, even if no further constitutional symptoms have shown themselves. There is no danger of taking these small or tonic doses of mercury for too long a period in this way, but there is often a tendency to tire of what seems unnecessary tediousness of treatment. If it is preferred, some of the other mercurial preparations may be used, or the agent may be introduced into the system by inunction, fumi- gation, hypodermic injection, or suppository. For inunction thirty or forty grains of the officinal ointment of mercury may be rubbed into the thin skin of the inner side of the arms or thighs at bedtime. Fumigation is accomplished by volatilizing a half drachm of calomel by means of a lamp placed under a metal plate upon which the drug is spread. Any apparatus which will allow this arrangement, and at the same time furnish an atmosphere warmed and filled with steam, is all that is required. The patient is divested of clothing, and surrounded by a rubber cloth extending from his neck to the floor. Under this covering the generator of mercurial vapor and of steam is placed, and thus the moistened cutaneous surface is subjected to the reme- dial influence. Such fumigation may be repeated every day for fifteen minutes, and is especially available in syphilitic skin affections. Internal treatment may be used in conjunction with these mercurial baths. The corrosive chlo- ride of mercury in doses of from one-thirtieth to one-tenth of a grain may be given hypodermically. All these methods, however, are too incon- venient for prolonged use, and will never supersede the ordinary mode of administration, except in especially selected cases. At certain times, be- cause of the inefficiency or undesirability of mercury, the preparations of iodine must be utilized. The iodides of potassium, sodium, and ammo- nium are usually adopted because of their cheapness, convenience, and efficiency. Iodoform is too offensive in odor, and many other prepara- tions are too expensive or bulky. The iodides seem more valuable in the late lesions of syphilis than in the primary and early secondary affections. They are to be given in ten to thirty grain doses three or four times daily, after meals, and preferably, perhaps, in alkaline solutions. The sodium iodide will often produce less coryza and mucous irritability than the commonly employed potassium salt, though the remedial power of the drugs is about equal. Upon some persons the iodides act as a Poison, and in very small doses produce coryza, conjunctivitis, cough, and a papular eruption. Usually, however, these disagreeable effects can be 6 & 82 SY PHILIS. obviated by combining a small amount of morphia with each dose, or by resorting to some other preparation of iodine. Before leaving the constitutional treatment of syphilis, it is necessary to remind the reader that many patients are so broken down by the effects of the syphilitic poison, or by previous conditions of ill health, either ac- quired or hereditary, that the use of corroborant remedies is imperatively demanded. Such cases require quinia, iron, mineral acids, stimulants, cod-liver oil, and concentrated food. It is often possible to keep up this line of action, while administering the small doses of mercury, or the iodides. If these remedies seem to interfere with digestion and produce anaemia, they must be suspended or reduced in amount for a time, and the reliance of the surgeon be upon the tonic and supporting regimen. It is a mistake, however, always to consider the prolonged course of mild specific medication a depressing agency, for in the majority of cases it is the syphilis that depresses, and the specifics which neutralize this poison are really the proper drugs to increase the health equation. Agents which tend to eliminate morbid matters from the blood are doubtless valuable; hence, Turkish baths and secretory stimulants probably are beneficial in the treatment of syphilis. Again, it is very often of advantage to combine the mercurial and iodine treatment when either agent alone does not beget favorable results. In very late lesions, unusually large doses of iodide of potassium, such as a half drachm or a drachm, largely diluted and taken after food three or four times daily, will occasionally work astonishing cures of painful con- ditions due to periostitis and nerve lesions. I usually give about thirty grains of the potassium iodide before each meal, and a half to one grain of the green iodide of mercury with a grain of tannic acid after each meal. These remedies should not be taken at the same time, as red iodide of mercury might perhaps be formed and poison the patient. Hereditary syphilis must be treated with mercury and iodine, combined with or occasionally replaced by tonics, in the same manner as acquired syphilis. The syrup of iodide of iron in twenty or thirty drop doses is often an eligible preparation. Warm clothing, good diet, and hygienic surroundings of the best character are important factors in bringing syphilitic children to adult life. It is probable that the subjects of in- herited syphilis are more or less protected against inoculation with syph- ilitic virus. Any incidental symptoms that occur during the progress of either ac- quired or hereditary syphilis must be managed on general principles. Thus, impaired digestion, constipation, fever, sleeplessness, and such con- ditions, may require laxatives, astringents, refrigerants, or hypnotics. The local treatment of syphilitic lesions is important, but far less so than the general treatment, except in the case of iritis. In iritis it is abso- lutely essential to drop immediately into the eye a strong solution of atropia (about four grains of atropia sulphate to the fluidounce of water); because, if this is delayed, the iris will become glued to the anterior capsule of the lens, and the permanently contracted pupil be occluded by the deposit of inflammatory lymph. Hence, wide dilatation of the pupil must be ob- tained at once, after which, or indeed during the same time, constitutional remedies are administered. Mucous patches and ulcerations should be touched with fused silver nitrate or a solution of nitrate of mercury (1 : 10). Cutaneous ulcers will heal more rapidly if slightly stimulated with diluted ointment of nitrate of mercury (1 : 10), or with some astringent, such as copper sul- T R E A T M E N T , 83 phate, silver nitrate, nitrates of mercury, iodoform, or chloral. The various remedial measures described under ulcers are applicable. The falling of the hair, technically called alopecia, may require stimu- lating applications to the scalp, such as alcohol, ointment of the nitrate of mercury, tincture of cantharides, tannic acid, and ammonia, suitably diluted. Iymphatic glandular involvement may be benefited at times by pres- sure, absorbent plasters and lotions, and by interstitial injections of alcohol or iodine. Periostitis, which often causes excruciating pain, may be relieved by blisters, or by subcutaneous incision of the periosteum, which relieves tension. Other operations may, at times, be required for the removal of diseased bone or irrevocably degenerated members. O H A P T E R V I. RICKETS OR RACHITIS. DEFINITION.—Rickets is a diathetic affection, and, therefore, should mot be described under disease of bone, but in the present connection. Its characteristic is an abnormal deposition of cartilaginous material, with incomplete Ossification. The effects of this constitutional condition are shown in softening and distortion of bones, and in changes resembling amyloid degeneration in the liver, spleen and other organs. PATHOLOGY..—Rickets seems to depend upon malnutrition, which causes deposition of abnormally large areas of soft, cartilaginous tissue which cannot be at once perfectly ossified by calcific transformation. Hence the bone is thickened by soft, subperiosteal, cartilaginous deposits, which do not add to its strength, because the medullary cavity is simul- taneously increasing. The bones are, therefore, easily bent out of shape. The epiphyseal cartilages, in a similar way, are enlarged, and, becoming imperfectly ossified, allow deformity in the vicinity of the joints. Marked deposition is apt to occur about the edges of the cranial and other flat bones. After a time excessive deposit of bone salts occurs, and sclerosis, or abnormal hardening, of the bones takes place. The visceral changes resemble amyloid or waxy degeneration. CAUSES.–The etiology of rickets is unknown. Heredity, food deficient in organic salts, and the presence of lactic acid or phosphorus in excessive amounts have been named, but not established as causative factors. Defi- ciency in amount of fresh food is an important factor in its production. SYMPTOMs.-Rickets is a disease of childhood, and appears about the second or third year of life. The premonitory symptoms are not distinc- tive, and no definite diagnosis can be made until the enlarged extremities of the long bones, the nodules at the junction of ribs and costal cartilages, and the bending of the bones by muscular traction and the weight of the body in walking, point out the rachitic condition. The child may be restless, sweat profusely about the head, show digestive derangement, exhibit irregularity in dentition, and complain of muscular pain upon moving or being handled. There is often no febrile movement. The liver and spleen are often enlarged, and the child listless, emaciated and somewhat sluggish in mental development. Osseous deformities of the limbs, anterior thoracic region, spine and pelvis are commonly exhibited in tuberous enlargements and curvatures. Partial or complete fracture may occur. The fontanelles close slowly, and the occipital bone may be- come thinned. These symptoms may abate, as if convalescence was at hand, and be followed by recurrence of symptoms. It is not usually a fatal disease, but recovery slowly supervenes, accompanied by abnormal induration of the distorted skeleton. TREATMENT.-The treatment must consist of feeding with the most nu- tritious food, as mother's milk, cow's milk, broths, etc., and the adminis- tration of cod-liver oil (fºss—ij three or four times daily), syrup of iodide of iron (mx-xxx), quinia (gr. i-ii), compound syrup of phosphates T R E A T M E N T . 85 (m, x-faij), or syrup of lacto-phosphate of lime (m, x-fºj). Fresh air, bathing and frictions are valuable adjuvants. “lºſſ During the stage of softening, deformity of the bones should be averted by prohibiting locomotion, and by the application of splints or plaster-of- Paris dressings. After convalescence, slight curvatures will often be cor- rected by muscular action during the growth of the child. If the deformity is great and permanent, osteotomy may be demanded to relieve lameness or to improve appearances. C H A P T E R V II. TUM.O.R.S. DEFINITION.—A tumor, or morbid growth, is a circumscribed enlarge- ment of living tissue, abnormal to the part and having no physiological function, which, in its growth, is independent of the adjacent structures, and which is not the result of an inflammation. It is an atypical new formation. Most cysts are not strictly tumors. Condylomata are inflam- matory formations, not tumors. CAUSES.—The cause of all morbid growths is abnormal activity of the cellular elements from which they originate, but the factors or primary causes inducing this morbid activity of prečxisting cells are not easily discoverable. It is probable that the cause of tumors is local rather than general, for, although blood alterations and hereditary conditions may influence their progress, the development of such morbid growths seems to depend on peculiarities of the tissue-cells. These peculiarities may be due to in- herited cellular eccentricity which readily responds to any existing cause, or to local irritation from injurious impressions or from the immigration of foreign elements coming from primary morbid growths situated at a distance. Many efforts have been made to prove the dependence of tumors, especially malignant growths, upon microörganisms, but thus far unsuccessfully. The most tenable theory for benign growths is that there has been left imbedded in the tissues a few embryonic cells, not em- ployed in the development of the animal in the prenatal stage of ex- istence, which, in after-life, assume activity and develop into tumors. It has been suggested that the occurrence of carcinomas is due to the normal resistance of connective tissue being reduced until epithelium, which has an active power of growth, invades it. PATHOLOGY..—Tumors are always developed from cells which have pre- viously existed, either at the present seat of the growth, or at some distant spot from which they have been transported to the locality occu- pied by the tumor. The tumor in the former case is a primary, in the latter a secondary, morbid growth. The histological structure and de- velopment of every tumor resemble, in a greater or less degree, some normal or physiological tissue—that is, all pathological formations belong to some physiological type. The resemblance is not exact, however; they are atypical. These axioms may be clearly illustrated by saying that no tumor can be formed from cloth or straw, but in its construction and growth must resemble some animal tissue. The original elements from which tumors are developed are cells of connective tissue, of epithelium, of glands, of muscle, or of nerve. The morbid growths originating from muscle- and from nerve-cells are rare, those arising from epithelial and glandular origins quite common, and those developed from a connective- tissue basis exceedingly frequent. A tumor whose structure is similar to the part from which it originated or in which it lies, is called homologous; one which differs from the tissue that gave it birth, or in which it is situated, is termed heterologous. P A T H O L O G Y . 87 These terms are somewhat relative ; for example, a cartilaginous tumor growing from the larynx would be homologous, but if appearing in the testicle it would be heterologous. Heterology is especially characteristic of malignant growths because they spread into tissues different from their original site, and are even transported, by the blood and lymph currents, to distant parts of the organism, such as the internal viscera. An important point in regard to the relation of the new growth to the adjacent tissues is the presence or absence of infiltration. If the tumor blends with the surrounding parts so that the microscope discloses tumor cells involving the muscular and cellular tissue of the neighborhood, infiltration exists and the tumor is diffuse. This infiltration is very common in malignant tumors, but may not be apparent to the unaided eye. A circumscribed growth is one which is definitely separated from the adjacent structures, which it has pushed apart during it development. It is often isolated from them by a capsule of condensed fibrous tissue. Such growths may, during their progress, become diffuse. Microscopic examination is the only test of the absence of infiltration even in growths which appear to be encapsulated. Tumors occasionally disappear by atrophy or absorption, and at times reach a certain bulk and remain stationary; but usually they increase in size. This increase frequently occurs rapidly even though the patient is losing weight. They may undergo changes, such as fatty degeneration, calcification, pigmentary, colloid and mucoid degeneration, inflammation, ulceration, and mortification, in a manner similar to tissues not patho- logical in their origin. Tumors have no nerves. The tendency which certain morbid growths have to be reproduced, either at the original site, after excision, or in other regions by infiltrating or infecting the tissues, is designated malignancy. Hence, tumors are malignant and non-malignant. Malignant tumors, as previously stated, are capable of infiltrating neighboring tissues with their cells; and by this and perhaps other means they influence such abnormal activity in the part that similar growths arise at the circumference of the original tumor. Hence, it is not unusual to see a neoplasm surrounded by a series of small nodules. When the surgeon removes a malignant tumor he may leave tissue which has recently been infiltrated with the tumor cells, but which appears to be normal. These cells, either by their own proliferation or by in- fluencing proliferation in the native cells of the part, cause a similar tumor to appear at the cicatrix and its vicinity. The development of Secondary tumors from malignant growths may occur in another way. The lymphatic circulation through the original disease may carry cells of the tumor to the nearest lymphatic glands, where they are arrested, and, as in the former case, induce secondary growths similar to the primary. A third manner of inducing secondary tumors is a similar transference of cellular elements by means of the blood current passing through the growth. These tumor cells are arrested by arteries or by veins in some distant capillary system, often the nearest, and, as in the lymphatic method of infection, induce secondary growths. Thus, it is evident that malignant tumors produce others like them- selves by infiltration and by lymph and blood infection. Other methods may at times, though rarely, be operative. Tumors often show a decided preference for one or other of these methods of reproduction. The sec- ondary growths may, in the same way, act as parents and produce a progeny with characteristics similar to their own. This transference of 88 T U M O R. S. cellular elements explains the circumstance that malignant tumors are frequently heterologous, It must not be forgotten, as it often is, that multiple tumors, even when malignant, may not be secondary to another, but may be synchronous or due to the same original cause. From the description given of the processes by which reproduction of malignant growths is accomplished, it is evident that the most malignant growths would be those containing the greatest number of cells, the most juice, and the greatest abundance of lymphatic vessels and blood vessels. The reverse of this picture would give non-malignant or benign tumors, which, as they approach the characteristics of the other group, become more or less malignant in nature. In fact, there is no absolute line drawn by nature dividing the malignant from the non-malignant; although it is admitted that tumors with one histological structure are usually malig- nant, and others usually benign, either class may occasionally assume the clinical nature of the other. CLASSIFICATION.—Tumors are classified according to their histological structure, which, as I have previously stated, always resembles, in a greater or less degree, some physiological tissue either of adult or foetal life. The imperfect knowledge that we possess of the development of many tissues, and the varying degrees of relative importance attached by pathologists to the microscopic elements seen in the growth, prevent a universal acceptation of a single classification. I have accepted that given by Green (Pathology and Morbid Anatomy), which is convenient for reference, and more familiar to the American profession, perhaps, than any other. CLASSIFICATION OF TUMIORs. I. Tumors whose general structure or type resembles one of the modifications of fully developcd connective tissue. Special types: 1. Fibrous tissue. Fibrous tumor. Fibroma. 2. Adipose tissue. Fatty tumor. Lipoma. 3. Cartilage. Cartilaginous tumor. Chondroma. 4. Bone. Bony tumor. Osteoma. 5. Mucous tissue. Mucous tumor. Myxoma. (not mucous membrane.) 6. Lymphoid tissue. Lymphatic tumor. Lymphoma. II. Tumors whose general structure or type rescimb/cs that of one of the higher or more comple:c tissues than fully developed connective tissue. Special types: 1. Muscular tissue. Muscular tumor. Myoma. 2. Nervous tissue. Nerve tumor. Neuroma. 3. Blood vessels. Vascular tumor. Angioma. 4. Lymphatic vessels. Lymphatic vessel tumor. Tymphangioma. III. Tumors whose general structure or type is that of the undeveloped connective tissue - of the embryo. * Sarcomas. These are named according to the shape and size of the predominant constituent cell (round-cell, giant-cell, etc.); according to the character of the stroma (osteo-sarcoma, myxo-sarcoma); or according to the retrogressive changes that occur in the tumor (melano-Sarcoma, calcifying Sarcoma). IV. Tumors whose general type is that of epithelial tissue. 1. Papillae of skin or mucous membrane. Papilloma. | Adenoma. 9 (§ - º 2. Glands. Carcinoma. T R E A T M E N T . 89 Under carcinomas, then, are : 1. Acinous carcinoma. a. Scirrhoma, or chronic carcinoma. b. Encephaloma, or acute carcinoma. 2. Epithelial carcinoma. a. Squamous epithelioma. b. Columnar-cell epithelioma; often called adenoid carcinoma. 3. Colloid carcinoma. W. Congenital miced tumors or terofonata. Tumors due to inclusion and imperfect development of one foetus within another, or abnormal development of a single foºtus. Dermoid cysts belong in this division. CLINICAL HISTORY..—Tumors present innumerable varieties as to size, form, consistence, number, situation, and other physical characteristics. These clinical attributes have much to do with the symptoms of the growth; for example, a small tumor passing on a nerve-trunk will pro- duce more pain than a large one in another locality; one overlying an artery will receive transmitted pulsation, another pressing upon a vein will cause mechanical dropsy. Certain tumors, especially the carcinomas, have a tendency to ulcerate and become the seat of hemorrhage. Those growths whose clinical history is conspicuous because of their infiltration of adjacent structures, recurrence after removal, and repro- duction in distant regions of the body, are called malignant. The car- cinomas and many of the sarcomas usually present this feature of malig- nancy; the other groups, as a rule, are not malignant. There are, how- ever, occasional exceptions, for sarcomas and even carcinomas sometimes act as non-malignant growths, while others, ordinarily benign, at times assume a decidedly malignant expression. CAUSES OF DEATH.-Death may occur from morbid growths on account of hemorrhage; asthenia due to excessive discharge; nervous irritation; mechanical interference with nutrition ; asphyxia; and profound involve- ment of the nervous centres. Many tumors have no tendency to impair the general health. This is especially true of the non-malignant growths. TREATMENT.—The treatment of tumors depends on their character. Malignant growths, and those suspected to have that character, should, as a rule, be removed by operation as early as possible. The excision should extend far beyond the apparent outlines of the tumor, because infiltration has probably taken place, though not appreciable to the eye of the surgeon. Benign growths may be allowed to remain if they neither interfere with the functions of the part nor cause indirect deterioration of health. If they show indications of probable future injurious influences they should be removed while still small, provided the excision can be done without great risk. If the tumor is more serious in its present or future aspects than the operation, operation is justifiable; but when the Operation is more serious than the probable effects of the undisturbed tumor, operation is not justifiable. In excising tumors involving deep structures and having firm attach- ments, the operator should endeavor at once to become master of the situ- ation by coping at first with the most troublesome portions of the growth. It is unsurgical to spend time freeing superficial adhesions and tying vessels which will in a moment be cut again at a lower level. It is far better to work under the deeper portions of the tumor, as soon as a free cutaneous incision has been made, and thus control the primary Sources of hemorrhage. This method of operating enables the surgeon 90 T U M O R. S. to appreciate more accurately the character of operative procedure de- manded for the extirpation of the growth. When tumors cannot be removed, relief of pain may often be obtained by open or subcutaneous division of the fascias binding them down, or by excision or stretching of nerve-trunks. Excision of insignificant tumors is often proper because of the unsight- liness produced by them, and the mental perturbation induced by their eXIS ten Ce. SPECIAL TUMoRs. I. Tumors whose general structure or type resembles one of the modifica- tions of fully-developed connective tissue.—Growths of this class are non- malignant, for when any of them, such as fibroma, enchondroma, and Osteoma, occasionally assume a malignant expression, it is found on micro- scopic examination that they are wholly, or in part, sarcomatous. This accords with the well-known fact that a tumor may present in its different parts the structure of more than one variety of morbid growth. FIBROMAs, OR FIBROUs TUMoRs.—These growths may be divided into soft and hard fibromas. The former grow somewhat rapidly, are smooth, rather soft and elastic, and often pedunculated; they are at times diffuse, though often circumscribed and encapsulated, and give rise to no pain or inconvenience except from their weight. On section they occa- sionally exude a large amount of serous fluid. The hard fibrous tumors are of slow growth, are smooth, very firm, usually single, generally movable unless having bony attachments, painless, and encapsulated. Fibromas, as a rule, have few vessels, but they are occasionally very FIG. I 0.

(Hol.MEs.) vascular, and then, as the fibrous surroundings of the vessels prevent re- traction and contraction, severe hemorrhage may follow their removal. Eibrous tumors originate from the fibrous tissue of the skin, connective tissue, subcutaneous and submucous tissue, periosteum, fascias, nerve- C HON DRO MAS, OR C A RTIL AG IN O US TU MO RS. 91 sheaths, and other structures; and are found in many situations. They constitute one form of epulis, a variety of naso-pharyngeal polypus, and the so-called false neuroma. The last is a fibroma developed from the connective tissue in the nerve and having nerve fibres spread over its sur- face. Such tumors are often multiple, and are painless. The painful subcutaneous tubercle is considered by some a fibroma which has no demonstrated connection with nerve-fibres; others think it is a true neuroma, or nerve tumor. Uterine fibroid tumors are usually myomas. Fibrous tumors may undergo softening, calcification, ulceration, and cystic degeneration. Microscopically, fibroid tumors consist of fibrous tissue more or less conpactly interlaced, associated with a few fusiform or star-like cells which are often indistinct. Rapidly developed fibromas usually present a greater proportional abundance of cells, and are soft in consistence. Some fibromas closely approach the sarcomas in their microscopical and clinical features. - The treatment of ordinary fibrous tumors consists in non-interference, unless their bulk or situation demands removal. They are non-malig- nant. LIPOMAS, OR FATTY TUMoRS. – A circumscribed accumulation of adipose tissue is called a fatty tumor. They occur anywhere, though especially about the back and shoulders. I once saw one removed from the palmar aspect of the hand; I think it was in the tissues of the ball of the thumb. Such tumors are of slow growth, though they may reach a very large size; are soft, doughy, and sometimes slightly fluctuating. Often they are distinctly lobulated and frequently cause a dimpling of the integument at the situation of the fibrous septa attaching the skin to the deep fascia; they may become pendulous, and even change their position under the skin by the action of gravity; they are painless and seldom undergo degeneration, softening, or ulceration. They consist of indistinctly nucleated cells distended with fluid fat and Connected by a variable amount of connective tissue. As these cells in- crease in number by proliferation they are filled with fat, and thus the growth acquires bulk. The mass is usually surrounded by a capsule of condensed connective tissue. It is their localization that distinguishes fatty tumors from ordinary obesity. If lipomas require treatment they are to be removed by means of a free incision through the skin, which enables the surgeon to turn them out of the capsule with great ease. No portion of the tumor should be left behind to reproduce the growth. CHONDROMAS, OR CARTILAGINoUs TUMoRs.—These growths are found especially among young patients, and are frequently connected with the bones of the fingers. They are rarely developed from prečxisting carti- lage. They occur also in glands, such as the parotid, testicle and mamma, and occasionally in the lungs. When connected with the phalanges of the hands or feet they are usually multiple, otherwise they are single. Cartilaginous tumors are smooth, hard and elastic, and often lobulated masses; of slow development, usually surrounded by a capsule, and non- malignant. - Occasionally, however, they are much softer than usual, grow rapidly, have no capsule, recur after removal, infect distant tissues by cell trans- ferrence, and present decidedly malignant characteristics. These tumors usually show, especially at their circumference, sarcomatous structure in- filtrating adjacent tissues; hence they are not to be considered true chondromas. 92 T U M O R. S. There is a form of tumor called osteo-chondroma, which consists of bone associated with cartilage and originates under the periosteum near the articular extremities of the long bones. They may become trans- formed into true Osseous tissue. FIG. 12. | #d ** zºs §º sº. * - * ~. $ N!!!" WZ $4% º Multiple enchondroma of fingers.

They exhibit cells with nuclear and granular contents enclosed in a matrix which varies from a hyaline to a fibrous MYXO M AS, O R. M UC O U S TISSUE TU M O RS. 93 or mucoid character. They are usually developed from the bone or from connective tissue, and not from cartilage; very occasionally they originate from costal, laryngeal, and other cartilages in the same manner as exos- toses grow from bone. It has been proposed to call these overgrowths enchondroses. Changes of a calcareous or ossific character quite often affect cartilagi- mous tumors. Sometimes portions soften in the interior of the growth and cause an appearance resembling cystic degeneration. If the size of enchondromas does not render them objectionable or dangerous, they may be left undisturbed. Under other circumstances excision of the growth or amputation of the affected bone is demanded. In the sarcomatous enchondromas prompt operation is probably the best treatment. OSTEOMAs, OR BONY TUMoRS.—These growths, which must be distin- guished from calcareous degeneration of tissue, are hard, painless, of slow development, and frequently immovable because of their firm attach- ment to bone. They do not acquire a great bulk, but may be multiple. Falls may cause fracture of such tumors. Inflammation of periosteum and bone will frequently give rise to Osseous masses, as is seen in long- standing periostitis and when callus is formed after fractures. These are not usually regarded as true tumors, but the line between them and other bony growths is not very definite, Bony segments are occasionally formed in fibroid and cartilaginous tumors, because of Ossific degenera- tion; and at times we have sarcomas associated with bony masses. These last may show signs of malignancy, and hence must be distinguished from true Osteomas, which are benign: Irregular masses of spongy bone are often Ossified chondromas. On section Osteomas resemble bone, showing lacunae, Haversian canals, and canaliculi. Some consist of cancellated or spongy bone surrounded by a thin layer of compact bony tissue, others are much more compact; while still others are so dense that they show no spongy structure, and are hence called ivory-like Osteomas. Bony tumors may originate from bone or its accessories (cartilage and periosteum), when they are denominated exostoses, except when they pro- ject into the medullary cavity and are called enostoses. The projections of bony tissue found associated with diseased joints and inflamed bones, usually called osteophytes, are not tumors, but inflammatory formations. The former are frequent upon the interior or exterior of the skull, the jaws, great toe, humerus, and femur; the latter about diseased joints, mus- cles, and other structures undergoing inflammatory process. Osteomas occasionally arise from the medulla of bone. Bony tumors are non- malignant, but may require removal because of deformity, interference With motion, pain, or ulceration of the overlying integument. Excision by bone-cutting forceps or saws, or grinding away with the burr of the surgical engine is the proper method of accomplishing removal. Subcutaneous Sawing or drilling followed by fracture may be valuable by affording relief of symptoms without entire excision. MYXOMAs, or MUCOUs TISSUE TUMoRs.—The most familiar growth of this class is the mucous tumor or polypus found in the nasal cavities. yxomas are soft, often fluctuating, smooth or somewhat lobulated, pain- less tumors, of slow growth, and surrounded by a thin capsule. On sec- tion they are yellowish-white or pinkish in color, and exude an abundant glairy fluid, which examination shows to be mucus. The gelatinous con- Sistence and intercellular mucous fluid are the physical characteristics of the growth, which consists of mucous tissue, such as is found in the 94 T U M O R. S. vitreous body of the eye and in the umbilical cord. Mucous tissue, which must not be confounded with mucous membrane, is a form of con- nective tissue which is translucent and possesses between its cells a fluid containing mucin. This resembles very much the connective tissue of the embryo, and, therefore, some authorities class myxomas with S&LI'CODO fl.S. Mucous tumors are always developed from some connective tissue, such as adipose tissue, bone marrow, or the connective tissue of the nervous structures and other organs. They may exist in combination with fatty, cartilaginous, sarcomatous, and other growths, and may undergo cystic change. On the other hand, various neoplasms may present a mucoid degeneration in spots which gives them the semblance of myxoma. Some tumors called colloid carcinomas are myxomas. The microscopical examination discloses oval, stellate, and spindle- shaped cells, which are generally nucleated and often possess elongated projections which mutually interlace. The intercellular substance is more or less hyaline, and is homogeneous. It is this that gives the mucous tumors their jelly-like nature and furnishes the mucous fluid, so charac- teristic of them. Myxomas, if not associated with sarcoma, are benign ; and if entirely removed, seldom, if ever, recur. Where there is a group of pendulous myxomas, as occurs in the nose, the removal of a large one may, by re- lieving pressure, allow smaller ones to increase, and thus reproduce the old symptoms; but this is not a recurrence of the original growth.

LYMPHOMAS, OR LYMPHATIC TISSUE TUMoRs.—These tumors are composed of lymphoid tissue similar to that which is found in lymphatic glands, Malpighian corpuscles of the spleen, Peyer's patches and solitary intestinal glands, the tonsils, thymus, pleura, marrow of bones, etc. They occur most frequently in adolescents or young adults; if of rapid develop- ment they are soft and often become very large, while if of slower growth they are hard and seldom attain any considerable size. Lymphomas may be found in almost any situation because, as is now known, lymphatic tissue exists physiologically in many localities formerly considered desti- tute of this structure. The usual original site, however, is the lymphatic glands of the neck, axilla, groin, thorax, or abdomen, whence the growth may extend by infiltration to other structures. The ordinary inflam- MYOM AS, OR M USC U L A R T UMO RS. 95 matory enlargement of lymphatic glands gives the same microscopical appearance, and such swellings may be considered lymphomas if they con- tinue to increase in size, and even when they merely persist without diminution of bulk. Lymphatic tumors may be lobulated because of successive involve- ments of a group or chain of glands; they are usually painless and do not tend to suppuration or degenerative changes. The microscope reveals a network of fibrils containing in its small meshes lymph corpuscles which are identical with white blood-cells. These cells sometimes show one or more nuclei, and sometimes are granular with no visible nucleus. At the points where the fibrils of the network or stroma cross, nuclei are occasionally seen. In rapidly developed lymphomas the cells are abundant and large and the stroma not very marked. These are the softer in consistence, and allow considerable milky juice to be scraped from a cut surface. When the tumor has grown slowly the network or reticulum is found to be well-developed and the cells small and relatively few in number. These are the hard variety of lymphatic tumors. Lymphomas are, as a rule, non-malignant, but those growths which are of rapid growth and richly endowed with cell elements sometimes infil- trate adjacent tissues and exhibit a malignant tendency. They are allied to the sarcomas. Lymphomas do not show a tendency to caseation or softening as do tuberculous lymphatic glands. Multiple lymphomas constitute an essential clinical feature of Hodg- kin's disease, which is a peculiar affection accompanied by intense anaemia. In leukaemia also we have lymphatic growths among the patho- logical changes present, but in this disease there is an increase of the white and a diminution of the red blood-cells, which conditions do not pertain to Hodgkin's disease. * The removal of lymphatic tumors may be undertaken if the growths are accessible and the patient in fair health. When the blood alterations associated with the existence of the tumors are evidently profound, as in Hodgkin's disease and leukaemia, no operation would be advisable or justifiable. II. Tumors whose general structure or type resembles that of one of the higher or more complea: tissues than fully developed connective tissue. MYOMAS, OR MUSCULAR TUMoRs, are growths consisting of non-striated muscular fibres usually combined with more or less connective tissue. Very rarely muscular tumors are formed of striated muscular tissue (rhabdo-myomas): these have been usually, if not always, congenital tumors. Myomas are of slow growth and are usually circumscribed by a sort of capsule, though at times they are not distinctly bounded; not infrequently they become pedunculated. They possess considerable firm- iness and solidity, are often multiple, and are benign. Their most common location is in the uterus, prostate gland, and digestive tube; hence, they show the characteristics of involuntary muscular tissue. From the abundance of connective tissue found associated with the bundles of muscular fibres, especially in long-standing tumors, these growths, when in the uterus, are often termed uterine fibroids or fibro-myomas. Myomas may undergo calcareous and cystic degeneration. Under the microscope are seen long fusiform cells of involuntary muscle, with their characteristic rod-like nuclei, arranged in bundles or irregularly disseminated through the tumor. There is seen also, except in Some recent tumors, a good deal of fibrous tissue. Myomas are inno- 96 ‘T U M O R.S. cent, but should be removed if it is possible to do so, when their location or their production of uterine hemorrhage demands operative relief. When such uterine tumors are developed near the lining mucous membrane, especially if pedunculated, they may be removed by forceps or écraseur. They are occasionally expelled by inducing uterine contraction with ergot. It may be necessary and advisable to remove the entire uterus by abdominal incision when such growths cannot be enucleated from the ab- dominal surface of the womb. NEUROMAs, OR NERVOUs TISSUE TUMoRs.—All tumors connected with nerve-trunks are not neuromas, for they may be fibromas, myxomas, etc.; nor are nervous tumors necessarily painful tumors, as might be sup- posed by some readers. A neuroma is a rare form of growth and consists principally of ordinary white or medullated nerve-fibres. Gray nerve- tissue may be found in neuromas, but it is exceptional. Such tumors are small, slow of growth, sometimes multiple, perhaps painful, and always develop in the course or at the end of a cranial or spinal nerve. A not infrequent situation is the end of a nerve-branch that has been divided in a previous amputation ; here they may be com- pressed in the cicatrix and give rise to much pain. The so-called painful subcutaneous tubercle is a fibroma, not a neuroma. Under the microscope nerve structure with some connective tissue is seen. Nervous tissue tumors are never malignant, but may require excision when painful. ANGIOMAs, OR WASCULAR TUMIORS.–Tumors consisting of newly- developed vessels, bound together by cellular tissue, are angiomas; hence dilatations of existing vessels, such as are present in varicose veins and varicose arteries, often called cirsoid aneurisms and aneurisms by anasto- mosis, are not properly termed angiomas. Simple angiomas consist of structures resembling normal vessels with unusual tortuosity and may have a predominance of venules or arterioles. The color of the growth varies on this account from pink to dark-red or purple. Such tumors are apt to be FIG. 17. congenital and small; and, some- times, present no elevation of the skin, being mere stains. They con- stitute the well-known maevus mater- nus or mother's mark. Cavernous angiomas are tumors which are made up of erectile tissue. This consists of a series of chambers, lined with endothelium and filled with venous blood, which circulates freely through these mutually con- nected spaces. The walls of the chambers are fibrous septa. The structure is similar to that of the cavernous portion of the penis, and gives such tumors an erectile char. acter, which is often accompanied Cavernous angioma of mouth and check by distinct pulsation. in a child of two and a half years. Cavernous angiomas are usually - of a blue tint; vary in size according to the amount of engorgement, though ordinarily giving rise to distinct prominence; often grow rapidly, especially in cutaneous and loose areolar M Y O M A S, OR M USCU L A R T U M O RS. 97 tissue; and are not markedly congenital. Injury to cavernous angioma is followed by profuse hemorrhage. Lymphatic vessels sometimes communicate with cavernous spaces, similar to those described as occurring in cavernous angiomas. A tumor is then formed, which is called a cavernous lymphangioma. There is also a form of lymphangioma which consists simply of a mass of lym- phatic vessels; being, in fact, similar to the simple angioma above de- scribed. The treatment of vascular tumors will be described in the section de- voted to diseases of the bloodvessels more fully perhaps than here. They are non-malignant; but some forms may tend to produce death by hem- orrhage, occurring from slight abrasion of their surface or from ulcer- ation. No treatment is demanded for angiomas which do not increase, nor threaten life from ulceration and hemorrhage, unless the deformity or personal disfigurement is a source of anxiety. Sometimes, though rarely, they atrophy spontaneously. Capillary dilatations situated solely in the skin, causing the pink discolorations often called port-wine marks, may be removed by puncturing with red-hot needles or electrolytic needles, or by applying caustics, such as chromic acid. These marks are often unac- companied by any increase in the bulk of the part. Under such circum- stances they can scarcely be called, with propriety, vascular tumors. Some of these superficial congenital discolorations gradually increase in thickness, and become true angiomas. Purely subcutaneous angiomas present themselves as spongy, doughy tumors, from which pressure expels the blood more or less completely, leaving in the fingers a much smaller tumor. If largely composed of arteries, they have a pulsatile character, and a murmur which causes them to resemble aneurisms. The pulsation, however, partakes rather of the character of a thrill than of a beat synchronous with the heart move- ments. The spongy consistence and the fact that pressure on one artery does not obliterate the thrill and murmur aid in diagnosis. The angioma, moreover, is, probably, not located in the course of an artery. Angiomas in bone resemble malignant tumors. Vascular tumors, which involve both the skin and the subcutaneous tissue, are easily diagnosticated. They may cause great deformity, and even erosion or displacement of the bones. The treatment of the subcu- taneous angioma and of this last form is identical, except that in the former case the skin should be lifted up in one or more flaps and preserved if excision or strangulation of the tumor is practised. The three methods of dealing with these tumors, which are sometimes called thick naevi, are injection of coagulating liquids, strangulation and excision. I believe the last to be the best in nearly all instances. Injec- tion is accomplished by introducing the needle of a hypodermatic syringe into the centre of the growth, and after tearing the tissue somewhat by Q-and-fro movements of the needle-point, forcing twenty minims of the liquid into the meshes of the tumor by means of the piston. Tincture of the chloride of iron, or a watery solution of similar strength, or chloride ºf zinc (gr. x to the fluidounce of water), are proper agents to employ, if ...this treatment is adopted. There is, however, danger of causing disfigur- !"; Scars from sloughing following the induction of too high a grade of inflammation. Fatal embolism has also occurred from fragments of the $9.8gulated blood being washed into the general circulation. This may ° guarded against to some extent, by previously encircling the tumor 7 98 T U M O R. S. with a ligature, or with a ring of metal or rubber, which is kept in place for a few minutes after the injection. The temporary ligature may be adjusted and kept from slipping, with more ease, by transfixing the tissue under the base of the tumor with a pin, under the ends of which the liga- ture is passed. Strangulation may be accomplished in three ways: An acupressure pin is thrust through the tissues under the base of the tumor, after which a stout cord is carried once around the mass under the ends of the pin, and is then tightly tied. Sufficient force should be used in making the knot to cut off all access of blood to the tumor, which soon sloughs off, leaving an ulcer to heal. It is often well to puncture the constricted tumor with a needle before making the second tie, in order to let the blood and serum imprisoned therein escape. The tumor thus be- comes more flaccid and shrunken, and the string can, probably, be tied more tightly, Two pins thrust through FIG. 18. 2& - £ at a right angle to each other are better { & salii than a single pin, unless the naevus is |− º h' Small. If the string has cut a groove, in which it will lie without slipping over the top of the tumor, the pin or Strangulation of vascular tumor by a pins may be pulled out after the knot pin and ligature. has been tied ; otherwise, the pin must be left in position until the parts have sloughed. A second method is to pass a double ligature under the base by means of a large ordinary needle, or one with a handle having an eye in the point. The two halves of the tumor can then be constricted by cutting the string and tying on each side. FIG. 19. Ligation of vascular tumor in halves by a double ligature passed under it. If the tumor has an extensive area, the double ligature, of which one- half should be stained black with ink, may be carried repeatedly through the tissues by a large ordinary needle. Between each puncture of exit and entrance a long loop of the double string must be left. By cutting with the scissors the stained threads on one side, and the white threads on the other, a series of ends are made which can be tied together to stran- gulate the tumor in sections. The adjacent ends of the separate portions of the ligature may be twisted around each other before the loop's arcs are tied, if there is danger of bleeding from the tying pulling the edges of the needle's punctures apart. Occasionally constricting a portion of an angioma has set up sufficient inflammation to obliterate the whole. The subcutaneous ligation of the whole, or of sections of the tumor, may be done by carrying a wire around the growth in the same way as described in the treatment of varicose veins. MYO MAs, OR M USCU LA R TU M O Rs. 99 This plan is well adapted, perhaps, to subcutaneous angioma, which may possibly atrophy without causing ulceration and scarring. The needle must, of course, be reëntered every time at the orifice of exit. FIG. 20. The third method of strangulation is a combination of the other two. First thrust a pin under the mass, then pass a needle carrying a double ligature under the pin and at a right angle to it. The two halves of the growth can then be tied, and the ligature will not slip over the sloping edge of the tumor. All of these operations must be carried out with antiseptic care. Excision of angiomas is, as a rule, I think, the best treatment. The tumor is thoroughly eradicated, the wound, if aseptic, heals more rapidly than the ulcer left after ligation, and there is not the offensive sloughing Ligation of large vascular tumor in sec- mass that remains unseparated for tions.

S. and then constricts the tissues and afferent vessels by strong cords tied around the ends of these pins, as in the pin or harelip suture. If the location is not convenient for using the pins, he carries strong cords through the tissues by means of specially made needles six or eight inches long, and ties the ends of the cords on the surface of the skin. The access of blood to the region of operation is thus more or less com- pletely prevented. After the incisions have removed the tumor, the pins or strings are removed one at a time, and the bleeding arteries ligated systematically. This method is easily applied, and requires no special skill for its successful employment if the surgeon only place the pins or liga- tures at a sufficient distance from the growth to allow room for incision to be made entirely outside of its limits. The cord must be strong, and tied with much force. I have broken strong fishing-line in tying a knot before operating in this manner. LYMPHANGIOMAS may be treated by ligation and excision, as described for the removal of arterial and venous tumors, if their extirpation is de- manded. PAPILLOMAS, OR PAPILLARY TUMoRS.–These growths resemble, and are usually, hypertrophies of the papillae of the part, and are covered by the variety of epithelium which belongs to the region. They seem to owe their origin to direct inflammatory irritation, and are of slow growth, though they may attain considerable bulk by coalescence of several smaller masses. When the epithelium is abundant enough to cover the numerous papillae and fill in the crevices between them, the tumor is somewhat smooth; but usually the various papillae and their branching outgrowths are separate, and give the growth a ragged or cauliflower appearance. Papillary tumors occur upon cutaneous, mucous, and serous surfaces, and present characteristics depending upon location. Sometimes they become pedunculated, and constitute one form of poly- poid tumor. Warts, as well as many horny growths and corns, are cutaneous papillomas. These have a hardened epithelium, except when kept moist, as soft corns are, and possess limited vascularity. The papillary tumors found about muco-cutaneous junctions and upon mucous membranes are larger, non-vascular, and softer. They occur especially about the anus and genitals, where irritating discharges cause their ex- hibition, and are also found in the bladder, larynx, etc. Serous papil- lomas are met upon the synovial membrane of inflamed joints. The soft variety of papillary tumor may become the seat of ulceration or hemorrhage. Many such excrescences about the anus and genitals were formerly described as syphilitic, but they have no specific origin, except in so far as the irritation of the mucous membrane may in some cases be the result of a venereal discharge. Any other chronic irritating secretion will induce similar growths. A papilloma consists of a projection of connective tissue, usually quite full of small round-cells, surrounding a loop or plexus of capillaries, and covered by a layer of epithelium. Papillary tumors are benign, having the epithelium only on the surface, and not distributed through the mass, as in epitheliomas. They may become malignant, however, by transforma- tion into epithelioma. Warts of a pigmented kind occur frequently in the aged. They should not be irritated, as they may thus be excited to assume malignant tendencies. Papillomas on mucous surfaces may give rise to hemorrhages; and in the bladder and urethra may obstruct urinary evacuation. Papillomas should be treated by removal with caustics, ligatures, or ... a ... * * * < *, * * *y * ºf gº < * * sº * - * * * & s * & * * A DEN O M AS, OR GL AND U L A R T U M OR S. 101 excision.

ADENOMAS, OR GLANDULAR TUMoRS.–Glandular tumors consist of such tissue as is found in secreting glands (the simple tubular glands of the mucous membranes and the compound, or racemose, glands, such as the mamma and parotid); but the tissue is not capable of performing function as a gland. They must not be confounded with lymphatic gland tumors, which have a very different structure and are called lymphomas. The tubular adenoma is found originating from mucous membrane, as of the vagina, rectum, stomach, and is often so closely allied to epithelioma that a distinction is well-nigh impossible. Racemose adenomas occur in the breast especially, and are often associated with fibrous and sarcomatous tissue, thus forming compound tumors. Adenomas are of slow growth, may be lobular in form, are quite firm unless undergoing cystic. degeneration, are usually surrounded by a cap- sule, and, when uncomplicated with other morbid growths, are benign. They sometimes undergo, in places, fatty or cheesy transformation. Glandular tumors of mucous membrane sometimes become pendulous and thus constitute a form of polypoid tumor. FIG. 23.

Tumo's whose general structure or type is that of the whdeveloped tissue of the embryo (Sarcomas).-Tumors consisting of connective tissue similar to that found in the human embryo are called sarcomas, and pre- sent variations according to the peculiarities of the cells and intercellular substance. The connective tissue of the embryo, before it is developed into the mature connective tissue of the foetus, consists of numerous small, round cells, with a very small quantity of soft and homogeneous material between them. As the connective tissue becomes more mature, the cells decrease in number and assume an elongated shape, while the intercellular material spoken of becomes fibrous. This maturing connective tissue finally develops into the perfect connective tissue, fibrous tissue, cartilage, and bone of the foetus and child. Sarcomatous growths are formed then of embryonic connective tissue, which, instead of maturing, continues to exist and to reproduce itself, thus causing progressive increase of the tumor. Small portions of the tumor occasionally reach a higher development and become fibrous tissue, cartilage, or bone, thus producing a mixed tumor; but this is not general or usual. The cells of sarcomas may be round, spindle-shaped, or very large and irregular. They are closely packed together with very little intercellular substance, which varies from a homogeneous fluid to a some- what granular or fibrillated material having considerable firmness, but which usually intervenes between all the cells, and does not allow them to Congregate together in groups. FIG. 24. Round cells. X 350. (GREEN.) Spindle cells. X 350. (GREEN.) These cells may all occur in one tumor, but the form which pre- dominates gives name to the variety, viz.: round-cell, spindle-cell, and giant-cell sarcoma. ... The round cells are either identical in appearance with white blood-cells, or they may have an indistinct nucleus and bright nuclei. The spindle or fusiform cells are oblong, terminate in fibrils, and have a long elliptical nucleus, with or without a nucleolus. The large irregular or giant cells, called myeloid cells because they resemble the cells of foetal marrow, are very much larger than the others, and are irregularly spherical with perhaps several prolongations, and contain many oval nuclei with bright nucleoli. They may not actually predominate in the tumor, but their presence is so evident that they give name to the variety in which they are seen. The blood vessels in Sarcomas are numerous, and on account of the small amount of matrix are scarcely separated from direct contact with the cells. SA R C O M A S. 103. Sarcomas always develop from connective tissue; hence, they have a general distribution and are found originating from muscular fascias, periosteum, lymphatic glands, and marrow of bones, as well as from the ordinary connective tissue beneath the skin and the cellular tissue of the viscera. They infiltrate the surrounding structures and thus extend by cellular invasion. There may be a sort of capsule, though the growth is usually diffuse. Fatty, cystic, calcareous, and other degenerations are liable to occur in portions of the growth; and sometimes sarcoma may be combined with other forms of tumor. This assumption of, or combi- nation with, sarcomatous elements accounts for the malignancy of certain tumors which are usually classed as benign. This has been referred to when speaking of Osteomas and chondromas. FIG. 26. ū’ - ºš "V. J GC&N.Y.

Many sarcomas are very malignant, infiltrating adjacent parts, recurring after removal, and finally producing secondary growths in the lungs and other regions. The round cell and the large spindle-cell growths are much more malignant than the small spindle or giant cell tumors. Soft and very vascular sarcomas are to be looked upon as being probably highly malignant. Sarcomas do not often affect the lymphatic glands, While the carcinomas do so with great frequency. The fact that the bloodvessels in sarcomas are in close relation with the cells accounts for the occasional rapid development of secondary tumors without lymphatic involvement. The cells readily penetrate the thin vessel walls and are garried along with the blood-current. In carcinomas, as will be seem later, the bloodvessels run in the fibrous network, or stroma, at a distance from the cells, which lie grouped in alveoli or pockets. Hence, dissemi- nation usually proceeds along the lymphatic channels before infection by the blood-current takes place. Round cell sarcomas present round cells which are similar to granula- 104 T U M O R. S. tion cells, which are larger than leucocytes and have an indistinct nucleus with nucleoli. These round cells are seen lying in a soft homogeneous or FIG. 27. $º) ()()(3) 93 (CXY)&@*@º sº º gº 㺠V §3(@, •Nº. &@ gº 33 º Ö sº §§§3) Öğ 2 § {}(3) © sº £ºſ 9%) Šº ſº S.X-3 22@@ §§ ºš) 22 §§ 㺠sº Šºš) hº §§§ º º sº º: sº º Small, round-cell sarcoma, showing vessels with mere embryonic wall.

Round-cell sarcomas are soft, and gray or pinkish in color upon section ; furnish a juice when scraped; are very vascular, and hence, are often stained by rupture of vessels and are liable to contain blood cysts. They rapidly infiltrate neighboring parts, give rise to distant sec- ondary growths, may even in- volve lymphatic glands, and in many other characteristics re- resemble clinically the form of carcinoma called encephaloid. The microscopic appearances serve to distinguish them from encephaloid with its stroma and grown-up cellular elements. Round-cell Sarcomas are, of course, as seen by their above-mentioned tendencies, very malignant. Glioma, the round-cell tumor found in the brain, retina, and cranial nerves, is a sarcoma. There is a round-cell sarcoma which shows an excess of intercellular structure in certain portions of the growth, so that there is a resemblance to the stroma of carcinomas. This has been called the alveolar sarcoma. Spindle-cell Sarcomas.—These are the most frequently found of the sarcomas, and consist of elongated cells with distinct oval nuclei and IFIG. 28.

The cells lie close together in parallel rows with little interven- ing substance, and sometimes give rise to a fibrous appearance until they have been teased apart to show their characteristic shape. If the spindle cells are small the growth is rather hard and probably is surrounded by C A R C IN O M A. S. 105 a capsule. Although it will recur after removal and will spread by in- filtration of surrounding tissues, it has little disposition to infect the internal organs and possesses much less malignancy than the large spindle- cell variety, which is soft, more vascular, and exceedingly liable to give rise to distant secondary tumors. Sometimes the cells are so broad as to be really oval in form. The small-cell growths are the recurrent fibroid tumors of the older writers. Sometimes spindle-cell sarcomas contain pigment granules deposited in the cells. This occurs especially when the tumor arises from a tissue containing pigment, as, for example, the choroid coat of the eye. These melanotic sarcomas are very liable to induce secondary pigmented growths in the internal organs, and are, therefore, very malignant, even if they have less disposition to local extension than some other forms. This tumor a few decades ago was often denominated black cancer. Calcareous and Osseous degeneration occasionally occurs; then the term osteoid sarcoma is used. This is very different from the benign growth called Osteoma. Giant-cell or myeloid sarcomas.-These tumors usually arise from bone and especially from the marrow. They contain large multinucleated cells, like those of foetal marrow, associated with spindle cells, and show little substance between the cells. The nuclei of the myeloid cells con- tain bright nucleoli. Myeloid sarcomas are usually quite hard, may be vascular, and frequently contain cysts. When they grow from the me- dullary canal the bone is expanded before them, and therefore manipula- tion of the tumor may cause a crackling noise. They frequently occur in the extremities of the long bones and in the jaws. They are less ma- lignant than the round and spindle-cell varieties of sarcoma. IV. Tumors whose general type is that of epithelial tissue (Carcinomas.) —The carcinomas consist of a fibroid network or stroma within the meshes or alveoli of which numerous cells of an epithelial type (epithe- lioid cells) are crowded together without any intermediate substance. A carcinoma may be readily illustrated by a piece of sponge (the stroma) within the cavities (alveoli) of which numerous grains of sand (cells) are grouped. A sarcoma, on the contrary, is represented by a quantity or mass of sand of which the grains (cells) all lie closely together with no sponge or stroma to form FIG. 30. distinct spaces (alveoli) for their reception. & -.

It must be borne in mind that similar cells are Seen in these morbid growths as in normal tissues. It is the characteristic arrangement of the cells, the variety of their shape and the stroma that distinguish carcinomas. There is no special carcinoma cell. The fibrous network or stroma of carcinoma is a more or less fibrillated Structure so interlaced as to leave numerous communicating irregular Spaces called alveoli, within which the cells already described are impris- (GREEN.) 106 T U M O R. S. oned. The amount of stroma varies very much and with its abundance the hardness of the tumor increases. It sometimes, especially if of rapid development, contains in its own structure a few cells. In the stroma, forming as it does the walls of the alveoli, the bloodvessels ramify. Hence FIG. 31. | y; gY º lſ the cells of carcinoma are sepa- rated from the vessels and do not as readily as in sarcoma enter the blood-current and cause rapid dissemination of the growth. The lymphatic vessels, however, which accompany the bloodvessels in the stroma, open into the alveoli, and thus readily allow entrance of cells into the lymphatic stream. This accounts for the early involvement of the neighboring lymphatic glands in cases of carcinoma, and its more frequent occurrence than in Sarcomas. Carcinoma cells originate from prečxisting epithelium, and therefore carcinomatous growths occur only where epithelium exists, as in the glands and cutaneous and mucous structures. This at least seems to be the opinion with most authority in its favor. After a time the epithelial cells burst through the epithelial basement membrane from which they origi- nated and thrust themselves among other tissues. This has probably given rise to the opinion that they developed from other than epithelial struc- tures. The stroma of carcinoma is partly newly developed tissue and partly the previously existent connective tissue of the part. The degenerative process occurring in carcinomas most frequently is fatty transformation which is always observable in a greater or less degree. It sometimes converts the tumor into a pulpy mass. Cystic de- generation sometimes occurs. Abscess may, though rarely, occur. The structure and clinical characteristics of the carcinomas have caused their division into these varieties: Acinous Carcinoma : a. Scirrhus, or Chronic Carcinoma. b. Encephaloid or Acute Carcinoma. Epithelial Carcinoma : a. Squamous Epithelioma. b. Columnar Cell Epithelioma. Any of these may undergo colloid degeneration and become the so-called Colloid or Gelatiniform carcinoma. The clinical characteristics of the carcinomas are important. They are exceedingly malignant, though epithelioma is usually less so than encepha- loid and scirrhus. They differ from sarcomas in that they generally infect the neighboring lymphatic glands and do not produce secondary tumors in the internal viscera until after the lymphatic glands in the vicinity of the primary growth have been affected for a considerable time. Sarcomas, on the other hand, rarely involve the lymphatics, but rapidly appear in the viscera, because of their dissemination by means of the bloodvessels, which have thin walls and ramify among the cells instead of running in a Stroma. # Epithelioma much less rarely reproduces itself in the viscera than the Stroma from carcinoma. X 220. (Holy(ES.) C A R C IN O M A. S. 107 other forms of carcinoma, though it ulcerates earlier. It usually, how- ever, infiltrates the adjacent tissue and involves the neighboring glands. The more rapid and the more vascular a carcinoma is, the greater are its malignant qualities; hence, encephaloid may be considered as having the greatest degree of malignancy. The secondary growths produced by carcinomas are usually of the same varieties as the primary tumor. If a carcinoma is incised, a comparatively abundant whitish juice can be scraped from the cut surface. This consists of the fluid and cellular ele- ments of the growth. Ulceration, sometimes attended by hemorrhage, is of frequent occurence in carcinomatous disease. Pain, of a darting character, is a not infrequent symptom. The word “cancer’ was formerly much employed to designate malig- nant growths. This was before the days of accurate pathological and microscopic investigation. Now, some authors attempt to limit the term to the class “carcinoma.”. This produces an unnecessary confusion, for “cancer’ has and can have no accepted scientific definition. It has no greater etymological value in the scientific surgery of the present time than has “hives” in dermatology, or “amaurosis” in ophthalmology. The word, therefore, should not be retained in surgical literature. Scirrhus, or chronic or hard carcinoma, grows very slowly, is very hard, is apt to be nodular, seldom attains a large size, and occurs usually in rather advanced adult life. At first it is unconnected with the over- lying skin, but soon becomes attached to the integument, and causes puckering and retraction thereof. As the disease advances the lymphatic glands in the vicinity become enlarged and ulceration of the skin over the primary growth occurs, producing an ulcer with ragged and nodulated irregular edges, secreting a foul mixture of sanious pus and blood. The pain in scirrhus, when present, is of a shooting or neuralgic character. Scirrhus is most frequent in the female mammary gland, and in the various parts of the alimentary tract. When the internal organs are involved secondarily, it may assume the form of encephaloid. Section of a scirrhous mass causes creaking as the knife divides the hard fibroid tissue, and shows a whitish shining surface, usually traversed by fibrous lines, and often concave on account of contracting influences.

Hence, the *erior, or older portion of a scirrhoma, approximates in appearance 108 - T U M O R.

Encephaloid, or acute or soft carcinoma.-This morbid growth is soft, having the consistence of brain tissue, grows rapidly; is very vascular, frequently showing large veins traversing the overlying integument, and when it ulcerates, gives rise to a fungous protrusion which is the seat of hemorrhage. Sometimes pulsation is perceptible, on account of the numer- ous large arteries in its structure. Encephaloid is not as frequent a growth as scirrhus, and it is found usually in the viscera as a secondary growth following a primary scirrhus of external parts. It does occur, however, primarly at times, especially in the testicle and breast. Many tumors of the eye and of the bones occurring particularly in young adults or children, formerly described as encephaloid disease, are now recognized as sarcomas. On section encephaloid tumors show a brain-like pulpy substance stained by blood extravasations and sometimes quite fluid from fatty degeneration. Encephaloid can scarcely be described as an entirely distinct growth from scirrhus; but its softness, its greater rapidity of growth, its less amount of stroma and absence of con- tractile tendencies, its vascularity, and its abundance of cells rapidly undergo- ing fatty degeneration warrant its desig- nation by a separate name.

Lipomas, chon- dromas, myxomas, sarcomas, and other growths undergoing change of a colloid or mucoid character may be mis- taken clinically for colloid carcinoma. The neoplasm has still less stroma than encephaloma, and the alveoli are large and very distinct, because of their distention with a mucilaginous or glue-like material. This colloid substance is transparent and colorless, or sometimes yellowish, and for the most part structureless, though a few epithelioid cells are seen. These cells are large and distended with the gelatinous material similar to that surrounding them. At times they differ little from ordinary carinoma cells. Sometimes they have a lamellar surface. Q Epithelioma, or skin carcinoma. Squamous epithelioma.-This is a more distinct variety of carcinoma than the others, though it does, at times, approach Scirrhus in its characteristics. It usually occurs at a muco- cutaneous junction such as the lip, eyelid, ala of the nose, anus, and prepuce; and appears first as a small nodule under the skin or as a scab or an ulcerated abrasion or fissure. It not infrequently arises at the situation of moles or warts. The tumor is quite firm and shows on sec- *... . . th #º #5 º U ºf gº --(?-? C A R C IN O M A.

Epithelioma is rare in young per- sons; soon exhibits ulcerative action, though of somewhat slow progress; commonly implicates the lymphatic glands but does not often infect the viscera; and is traceable to traumatic irritation of the muco-cutaneous tissues more frequently than the other carcinomas.

A lobulated pavement-cell squamous epithelioma showing pearly bodies. (Drawn by DR. CIIARLEs B. WILLIAMs.) The cells of ordinary epithelioma resemble the squamous epithelium of skin and mucous membrane, and contain one or more nuclei. They may be flattened by pressure, but have not the varied shape of the other 9."ºomatous cells, nor do they so readily assume degenerative changes of a fatty kind. They are grouped in the alveoli of the stroma, some- 110 T U M O R. S. times as tubular prolongations or plugs, and tend to form nests or “pearls’’ formed of concentric layers of flattened cells, which resemble the structure of an onion. These epithelial globes or nests are very characteristic of epithelioma, though not essential. They grow down from the surface into the lymph spaces of the connective tissue like nails or plugs. They merely signify that there is a rapid growth of squamous epithelium and may occur in epidermic structures not carcinomatous. The stroma is rarely so markedly alveolar as in the other members of the carcinomatous group, and may be quite limited in amount. It is represented by a fibrous-like tissue or by a tissue filled with small round cells surrounding the epithelial nests. Columnar epithelioma–When epithelioma occurs in the intestinal tract the cells are of the colummar or cylindrical variety found in the mucous glands of these parts, appear in more distinct alveoli, and usually do not form concentric nests. The growth closely resembles adenoma. obliquely, the others transversely; the epithelium is irregular in shape and size and is sometimes arranged in more than one layer. The stroma is fibrous, containing small round cells. (ERICHSEN.) Epithelioma originates from the epithelium of the skin, mucous mem- branes, and glands; and then the proliferation of epithelium which occurs causes invasion of the adjacent structures, whether they be connective tissue, muscle, or bone. It is the presence of epithelium in these unusual localities that is the essence of the morbid growth. Rodent ulcer is a form of epithelioma. V. Tumors consisting of a sac with contents (cystomas, or cystic tumors).- A cavity separated from neighboring tissues by a sac wall and having fluid, semi-solid, or soft contents is called a cyst or cystic tumor. Such tumors may result from the development of a sac-like cavity in tissues where no sac or cyst previously existed. These are true tumors or morbid growths, and are due to softening of structure, as occurs in fatty and mucoid degeneration; to separation of connective tissue by a secretion or deposition of fluid, as serous and blood cysts; and to the development of a sac around foreign bodies and parasites. In all these cases condensa- tion and irritative development of connective tissue lead to the formation of a circumscribing capsule or sac wall. Cysts are more frequently developed by slow accumulations within a C Y S TIC TU M O R. S. 111 dilation of a prečxisting cavity or duct. These are not true tumors, but are usually conveniently considered as such in connection with the form just mentioned. The contents are the natural products or secretions of the part, more or less altered by the changed conditions to which they are subjected. Such cysts are developed when the duct of a secretory gland becomes occluded, as is the case in sebaceous, mucous, salivary, and other retention cysts; when a ductless cavity secretes more fluid than the absorbents can remove, as in hydrocele, bunion, and bursal tumors; when the blood is poured into a cavity, as in haematoceles. e The wall of a cyst may be thick or thin, tough or friable, slightly or firmly adherent to surrounding tissues, and is developed by condensation and new growth of the circumscribing connective tissue. In the second variety of cystic tumors the wall presents the features of the gland or membrane from which it was developed, and has a similar epithelial lining. Cysts may contain serum, saliva, milk, semen, sebum, blood, and other materials, and often take their name from the contents. The congenital cysts, which consist of a wall resembling skin contain- ing epithelial structures, and those cysts, enclosing teeth and bones, found in the abdomen and supposed to be imperfectly developed ova, are called dermoid cysts. The hydatid cyst is a peculiar tumor due to the presence in the tissues of a parasite. This parasite is the undeveloped taenia echinococcus, which infests animals of the canine family but never progresses to full maturity in the human subject. The ovum having been introduced with food into the human system, develops as far as its cystic stage. The irritation due to the parasite in the tissues causes the formation of a sac or cyst wall from the surrounding parts: within this lies the parasite, which is itself a distended sac without any head, hence called an acephalo-cyst. It con- tains a transparent, non-albuminous or almost non-albuminous liquid of low specific gravity, in which are floating heads or the hooklets belonging to the heads of this form of worm. These heads are called echinococci. The echinococci may be adherent to the inner wall of the bladder like para- sites. Hydatid tumors occur most frequently in the liver, lungs, muscles, and subcutaneous tissue. Various changes occur in cystic tumors. Thus, the contents may become inspissated, fatty, or calcareous, and the wall may calcify, ossify, or even undergo cystic or other degenerations. Sometimes inflammation of the tumor supervenes, which leads to suppuration, discharge, or ab- Sorption of the contents, and cure by granulation. Occasionally, instead of cicatrization occurring, a foul chronic ulcer is left. A cystic tumor with one cavity is called simple or unilocular; one With several cavities, compound or multilocular. It must be remembered that many of the tumors previously described may undergo cystic de- generation by mucoid or fatty change taking place in their interior. The treatment of cystomas consists in their removal or their obliteration by evacuation of contents and destruction of cyst walls. True cystomas are benign, but may, as other malignant growths, cause death by their Situation and size. If they are excised every portion of the cyst wall must be removed, lest the part remaining become the starting-point for a similar tumor. Cystic sarcomas and other tumors that have undergone Cystic degeneration must be treated as growths of their own class. 9bliteration of cysts may be accomplished by tapping, internal scarifi- cation, injection, and incision. If the contained fluid is not viscid it may 112 T U M O R. S. be withdrawn with a trocar or aspirator; this causes collapse of the sac. Usually the cyst refills, but occasionally the irritation resulting from the puncture is sufficient to cause plastic inflammation of the interior of the cyst and adhesion of the walls. Thus, obliteration of the cavity and cure result. The cure may at times be accomplished by scarifying the internal surface of the cyst wall with a tenotome or long needle thrust into it at one or at several points without evacuating the fluid, which escapes into the surrounding tissues and is absorbed, or undergoes absorption during the progress of the resulting inflammation. This method is very satisfactory in treating hydrocele in infants. Multiple puncture and abrasion of the vaginal tunic with a needle seldom fail to cure such cases. When tapping or scarification fails to induce obliteration of cysts with liquid contents, it becomes necessary to inject into the cavity some irri- tating fluid to set up inflammation of a plastic grade. The best agent is carbolic acid liquefied by moderate heat or a few drops of water or glycerine. Tincture of iodine, wine, and other irritating and astringent solutions may be employed. The quantity should vary from twenty minims to a fluidrachm, according to the size of the tumor, and should be left within the cyst cavity. Cysts with thick cheesy contents, if not excised, should be split open. The surgeon must then scrape out the contents, and, if he does not re- move the cyst wall, he must mop the interior of the sac with strong car- bolic acid or some strong astringent or cauterizing application, and leave the wound open to granulate. This destroys the secreting surface of the wall and sets up inflammation, which, by means of the granulating process, causes the wound to heal and the cyst to become obliterated. O H A P T E R W III. WOUNDS AND SHOCK. DEFINITION.—A wound is a sudden and recent solution of continuity of the soft parts caused by mechanical violence. A solution of continuity of such tissue produced slowly by mechanical pressure or violence, or by inflammation idiopathically, is an ulcer; a solution of continuity of bone is called a fracture; hence, the term wound gives the idea of sudden vio- lence to the soft tissues of the body. This mechanical violence is usually directed from without, but it may arise from within, as is the case when wounds are produced by muscular efforts or by the projection of frag- ments of bone in fractures. VARIETIES.—Wounds are either freely exposed to the external air when they are called open wounds, or are protected from such exposure by the more or less perfect integrity of the skin, when the term sub- cutaneous is applied. A wound communicating with the air by a small cutaneous opening may still be considered a subcutaneous wound, as are also wounds beneath the mucous membranes, though the term, in this instance, is a misnomer. 4. For convenience of description I classify wounds under four heads: 1. Contused, or those in which the injury consists in a crushing or bruis- ing of the parts, with or without rupture of the integument, 2. Incised, or those in which the tissues are divided cleanly, or cut, as by a sharp knife, and in which the length of the wound greatly exceeds its depth. 3. Punctured, or those in which a wound is made by a pointed instru- ment, and in which the depth exceeds the length. 4. Lacerated, or those in which the structures are torn apart, giving, therefore, irregular edges to the wound. All wounds are referable to one of these groups, though they may possess additional characteristics: thus, any wound infected with a specific poison becomes a poisoned wound; if the vulnerating body enters a cavity, as the chest or a joint, a penetrating wound results; and missiles thrown by the explosive force of gunpowder produce con- tused or lacerated injuries, called gunshot wounds. SYMPTOMS.–Contused wounds are produced by blows or by sudden forcible contact with surfaces that have no sharp edges. The typical Contused wound is the ordinary bruise or contusion in which there is no laceration of the skin; ordinarily, however, contused wounds are lace- rated wounds in which the bruising is a more prominent feature than the laceration. I consider a simple bruise or contusion a contused wound, because there is a solution of continuity of the subcutaneous tissues in *ll such cases. Contused wounds may involve the skin and superficial fascia only, or may extend also to the muscles and deep structures. I have seen the muscles of the arm so pulpefied that amputation was re- Quired, though the skin appeared scarcely injured. In persons with a 8 ºut deal of subcutaneous fat a slight degree of pressure, as from a pinch with the fingers, will cause a distinct bruise, because the vessels are * readily ruptured. The characteristics of this class of wounds are dull 8 * 114 SH O C K. pain or numbness, a black and blue color at the seat of injury due to extravasation of blood from the ruptured capillary vessels, some swelling from effused serum, little or no hemorrhage from any accompanying laceration of the skin that may exist, and a tendency, if the contusion be severe, to the production of abscess and gangrene. Abscess and gangrene result because a place of least resistance is produced in the injured tissues and because the cellular vitality is impaired, thus giving opportunity for bacterial action. - When structures are divided by a keen instrument and the length of the wound is a more conspicuous feature than its depth the term incision or incised wound is employed. Incised wounds are characterized by acute pain and hemorrhage, a tendency to retraction or gaping of the edges, and rapid cicatrization. These features vary, of course, with the locality and extent of the injury. The bleeding washes away bacteria and tends to keep the wound aseptic, hence the rapid healing often seen. Punctured wounds are those inflicted by a pointed instrument piercing the tissues, and hence they are remarkable for depth rather than for linear extent. A wound one inch long and a half inch deep made by a knife is an incised wound; one of similar extent, but three inches deep, is a punctured wound. Punctured wounds vary according as they are made with dull or sharp pointed instruments; in the former case they resemble lacerations, in the latter incisions. As a rule, however, it may be said that punctures are accompanied by great pain and slight hemor- rhage. They are especially liable to be followed by severe inflammation, because they are not likely to be kept as free from bacteria as are those wounds which bleed profusely and which are readily cleansed. Wounds produced by disruption or tearing asunder of the tissues are termed lacerations or lacerated wounds, and are frequently accompanied by contusion of the parts. In fact, a force which causes crushing of the tissues without much tearing of the integument, gives rise to a contused wound, while the same force, so applied as freely to rupture the skin as well as underlying structures, is said to cause a laceration. Lacerations are distinguished by irregular jagged edges, moderate pain, slight hemor- rhage, little gaping, a tendency to suppuration and sloughing of the edges and slow cicatrization. These features depend upon the method of injury, for it is the tearing and twisting of the vessels and nerves that prevent bleeding and acute pain, and the devitalization and irregularity of the torn edges that occasion sloughing, favor microbic infection, and prevent rapid healing. SHOCK. DEFINITION.—The constitutional symptoms that immediately follow the receipt of a wound or injury, if it be sufficient to induce general dis- turbance, are grouped under the head of shock or collapse. Subsequently the general symptoms pertaining to inflammation arise, if the lesion is grave enough to cause an active process of this kind. Delayed shock I believe to be impossible. Cases so named are doubtless instances of fat embolism, sapraemia, septicæmia, or other imperfectly understood con- ditions." SYMPTOMS.–Slight shock is shown by pallor of the skin, a sense of giddiness and nausea, and a feeling of approaching unconsciousness. This is but temporary, and reaction or return to the physiological condition 1 For a résumé of this subject see article on Collapse in Holmes's System of Surgery, American edition, Phila., 1881. T R. E. A. T M E N T. 115 quickly occurs. When severe shock is present there is great depression exhibited by muscular relaxation, pallid and shrunken features, a lan- guid and bewildered expression, clammy sweating, a frequent and per- haps intermittent pulse which sometimes it is said may be slow, shallow and gasping respiration, a lowered bodily temperature varying from one- third of a degree to two or three degrees below normal, and nausea and vomiting. Usually the mind is clear or at most only slightly affected by aberra- tions of the special senses. The tranquil mental condition of patients suffering from profound shock due to grave railroad mutilations is often very distressing to the observer. If these symptoms of shock continue the patient dies, usually before inflammatory processes begin at the seat of injury, from cardiac failure. - In sudden death the heart may be spasmodically contracted, but oftener perhaps, the right cavities and venous trunks are engorged with blood. Recovery from shock, takes place by the depression stage being fol- lowed by reaction, which is evidenced by increasing power and slowing of the pulse, by a healthier hue of skin, a rise in temperature, and a dis- position on the part of the patient to change his posture. Reaction may be inordinate and pass across the health line to the domain of constitu- tional over-action when symptoms akim to asthenic inflammatory fever occur. It is usually preferable, however, to have an excess rather than a deficiency of reaction, since it is easier to control force than to create it; but the condition of excitability, coupled with prostration, must not be mistaken for excessive reaction. The time at which reaction occurs depends on the nature of the injury and the recuperative force of the individual, and varies from minutes to hours. The degree of shock varies with the severity of the injury and the impressibility of the patient. The greater the extent of the injury and the more important the structures involved, the more profound in a given patient will be the shock. On the other hand, however, we find that an impressible person will show great shock upon the receipt of a trivial Wound, while a much more serious lesion in another man will be accom- panied by little shock. Shock is greater in injuries of the trunk than of the extremities, and in wounds of the abdomen than in those of the chest. In estimating the degree of shock and in diagnosticating the condition itself the surgeon must remember that direct injury to nerve centres, hemorrhage, fat embolism, rapid septicæmia, and abstraction of heat from internal viscera, and fright are liable to simulate or increase the symptoms of shock. The heart and kidneys should always be examined prior to operations, because chronic disease of these organs increases the severity of the shock of Operation. The pathological condition causing the symptoms termed shock lies in the sympathetic nervous system, and is probably a paralysis of the vaso- motor centres. The perturbation of the vaso-motor nerves produces a Spasmodic contraction of the minute bloodvessels, and then lowered tem- Peature, pallor and the concomitant symptoms are exhibited. . TREATMENT—The treatment of shock will be discussed here, because in severe injuries the surgeon's attention is directed to this condition before local measures for the cure of the wound are adopted. I shall then recur to the subject of wounds and consider the modes of healing and the treatment of the different classes of wounds, If the Symptoms are slight a drink of water and fanning the face are 116 SH O C K . sufficient treatment. In severe shock perfect quiet of mind and body in the recumbent position and heat to keep up the bodily temperature are the most important requisites. Cardiac stimulants and food are then demanded in the majority of cases. Venesection, recommended by some authors because of the occasional engorgement of the veins and right heart, is probably never required. The distention of the hollow organs occurs from the vaso-motor nervous disturbance causing paralysis and is a result, not a cause of the shock. Heat and artificial respiration will be well calculated to distribute the blood engorging the viscera. Heat is to be maintained by warm rooms, blankets, bottles, or rubber bags filled with hot water, hot water enemas, or by the hot bath in which the temperature is raised from 98° to 110° F. A small amount (fā ss–f5 ij) of stimulant in the form of brandy or whiskey, may be administered ; but it should be remembered that many injured persons have been given alcoholic stimulus by the bystanders before the surgeon's arrival, or have taken it as a bever- age before the accident. Overdosing with such remedies produces de- pression. Hence, the amount spoken of above should seldom be increased but may sometimes be repeated at the expiration of several hours. Small amounts of coffee, beef tea, or milk also should be given at intervals, but here, as in the case of alcohol, large amounts lying unabsorbed in the stomach do harm and may induce vonmiting. The pulse is the indication to guide the attendant. If it increases in force and diminishes in rapidity reaction has begun. Time is then re- quired; reaction from severe shock may extend over six, twelve, or twenty-four hours. The drugs employed in the management of shock are morphia (gr. 3–3), tincture of digitalis (m, xx-f: j), carbonate of ammo- nium (gr. v-xx), atropia (gr. Cº-º), all of which can be given hypoder- matically; and quinia (gr. v-xx), best given by the mouth or rectum. Ether in half-drachm doses may be given subcutaneously. I have obtained in profound and almost hopeless shock very gratifying results, which I believe due to the hypodermatic administration of digitalis, ammo- nia, and alcohol. As soon as reaction is fairly established cardiac stimulants must be stopped lest the traumatic or inflammatory fever be enhanced. When operations are necessary after injuries inducing severe shock, the surgeon should wait, as a rule, until reaction has begun, since there is then less danger of causing dangerous depression from the shock of operation. Etherization has usually a stimulating effect and seems to combat the symptoms of shock. The shock after operations is often excessive because the surgeon has been too slow in his operative work, has exposed the patient to cold air, has reduced his temperature by wet dressings and irrigation, or has de- pressed him by prolonged anaesthesia. C H A P T E R IX. MODE OF REPAIR AND TREATMENT OF WOUNDS. REPAIR OF WOUNDS.—All wounds, large or small, open or cutaneous, incised or punctured, contused or lacerated, heal by that reparative pro- cess which I have, in the first chapter, called inflammation. In other words, what was there styled inflammation is really nature's reparative effort to reconstruct the injured tissues and limit the injurious influence of the origi- nal irritant. The processes called inflammation are efforts, often more or less futile, to restore physiological conditions. Inflammation is not a dis- €3,862. When the wound is of such a character that accurate adjustment of the Several tissues can be and is accomplished, a reparative effort merely suffi- cient to supply a small amount of fibrine or lymph supervenes. This fibrine glues the parts together, then becomes changed into granulation tissue, and finally into connective tissue, or scar, analogous to the original structures. Thus is repaired the breach of continuity. This method of union is union by first intention, or fibrinous repair, and occurs when no foreign body, clotted blood or undue amount of transudation prevents accurate approximation, and when the parts are kept quiet and the patient's tissues are in a healthy condition and free from microbic infec- tion or other irritation. By this mode are repaired subcutaneous and other aseptic wounds. When there is a loss of substance, or an irregularity of the edges of the wound, the space or chasm due to the injury or to the destruction of the ragged edges by sloughing is gradually covered and more or less filled up with minute granular bodies of a pink color called granulations. These are formed from lymph, capillary loops and indifferent cells in the same way as the uniting band in cases of union by first intention. If the wound is kept aseptic there will be no suppuration and epithelial formation will occur when the granulation tissue has filled up or nearly filled up the cavity. In the meantime there will be a serous exudate from the surface of the granulations. It is difficult to keep pyogenic organisms away from such wounds when large and superficial suppuration is not unusual. Absolute asepsis should be attempted always. . The granulations have absorbent power and are gradually converted into a bluish-white connective tissue, called the cicatrix, which occupies the situation of the wound and assumes characteristics similar, though not identical, with the structures injured. This method is union by second *tention or granulation. It is the only means by which healing of Wounds can occur if union by first intention fails to take place. It is apt to occur in contused and lacerated wounds unless they are subcutaneous or have their devitalized edges trimmed off, are rendered aseptic and accurately approximated. Other varieties of healing have been described, but they are but modifications of the two here considered, which them- selyºs are identical in pathological significance and process. Healing by first intention is much to be preferred, because it requires 118 MODE OF REPAIR AND TREATMENT OF wou N'Ds. much less time, say from two to seven days, and leaves very little cica- trix. Union by granulation, or second intention, requires weeks or months, according to the size of wound or ulcer, and leaves a large scar, which often gives rise to deformity, on account of the contractile tendency of cicatricial tissue. TREATMENT OF WOUNDS.–In the management of all wounds, there are four cardinal rules: 1. Arrest hemorrhage. 2. Render the wound asep- tic by removal of all dirt and foreign bodies, as far as it is possible to do So without incurring risk. 3. Bring the parts into apposition, if the attempt does not, and will not, cause pressure and tension. 4, Assist the matural reparative process by mechanical rest and the prevention of putrefaction and suppuration. These precepts apply to every wound, but their relative importance varies with the character of the injury. Thus, in incised wounds there is often much bleeding to be arrested, but no foreign body to be removed, while in contused and lacerated injuries there is frequently no hemorrhage, but numerous particles of foreign materials, such as shot, shreds of clothing and dirt, to be extracted. The arrest of bleeding will be spoken of under Diseases of the Blood- vessels, and the methods of approximating and dressing wounds, and of preventing germ infection under Minor Surgery and Surgical Dressings, Hence, I shall at this point speak only of the constitutional treatment required by patients suffering from wounds. To coöperate with the processes of repair and to prevent the occurrence of retarding complications may or may not require the surgeon's interference. In aseptic wounds, union usually occurs steadily and expeditiously, and nothing is required but patience on the part of the attendant, who has dressed the wound with germ- free applications. At other times, because of the contaminated nature of the wound or because of the conditions or surroundings of the patient, sloughing, burrowing of pus, abscesses, erysipelas, or pyaemia, render the surgeon's duties responsible in the highest degree. As all wounds heal by the reparative efforts of nature, inaccurately called inflammation, the treatment detailed on previous pages, for the management of the inflam- matory process is to be pursued. Hence patients showing a sthenic form of constitutional implication must be depleted and depressed by. bloodletting, purging, arterial sedatives, and other measures of a kindred nature. The asthenic type, on the other hand, demands supportive treat- ment, which is effected by tonics, stimulants, and a generous nutritious diet. Wounds must be treated locally according to their special characters, after the general rules given above have been followed; but, in all cases, the most rigid asepsis or antisepsis must be carried out. There is no doubt that serious complications arising in connection with wounds, whether the wounds be accidental or operative, can be mostly, if not entirely, avoided by keeping the wound-surfaces free from microörganisms. It is to these organisms, either introduced at the time of injury or allowed to come in contact with the wound at a later period, that the constitutional disturbances, slow healing, and suppuration so often found, are due. It is the surgeon's duty to avoid such microbic infection in operation wounds, and to limit it in accidental wounds when it has taken place before he had control of the patient's destiny. Death is often, and has often been, due to the surgeon’s ignorance or neglect of these precautions. This sub- ject will be further discussed, under Surgical Dressings, in the next section. Treatment of the Different Classes of Wounds.-Contusions, being subcu- T RE AT MIE NT OF W O U N DS. 119 taneous wounds, require little treatment. If there is a great deal of sub- cutaneous extravasation, cold water and pressure with a bandage are indicated to stop the hemorrhage. Absorption of the effused blood takes place very slowly, but gradually the black and blue appearance changes to a greenish and yellowish hue, and the discoloration then disappears. Alcohol, chloride of ammonium solution (gr. X-xx to the fluidounce), tincture of armica and hot water are often used as external lotions, but the benefit derived from them is doubtful. They do no harm, however, and serve to satisfy the patient. Moreover, the rubbing which they encourage probably assists the vessels in taking up the effused blood. If the extra- vasation is very great in regions where loose connective tissue is abund- ant, as in the eyelids and scrotum, the swelling will be so great that the surgeon may be tempted to make incisions for its escape. This is usually bad practice, because large amounts of blood thus effused will be absorbed, while contact with the air renders access of pyogenic or putrefactive bacteria probable. When extravasation of blood and rapid inflammatory effusion of serum cause such swelling and tension that the limb becomes cold and there is danger of gangrene from interstitial pressure, long incis- sions must be made through the tense skin. The skin then retracts and relieves the pressure. These incisions must be made with antiseptic pre- cautions, and the whole limb dressed with gauze. When absorption does not occur, but there remains a tumor filled with fluid blood for a long time, the term haematoma is employed. This usually requires aspiration or incision. Abscesses and serous cysts occurring subsequent to contu- sions demand evacuation. The treatment of open contused wounds and of lacerations may be con- sidered together, because the same principles govern their surgical manage- ment. Such wounds are nearly always infected with germs, from con- tact with the vulnerating body or from their surroundings at the time of their infliction. Before the wounds are dressed, it is very necessary to render them aseptic. This is done by the removal of all particles of dirt with aseptic forceps or fingers, and by cleaning and disinfecting the wounds by means of irrigation with antiseptic solutions. Corrosive subli- mate solution (1 : 500 or 1 : 1000), poured upon and into the wound from a pitcher or a syringe or squeezed from a sponge, is one of the most effective of such agents. Betanaphthol and other substances may be employed. All accidental wounds must be thoroughly sterilized in this manner in order to avoid the occurrence of suppuration. In large Wounds where such a procedure would give pain, it is not only justifiable, but it is requisite, to give ether in order that this important procedure may not be omitted. It is good surgery, after having etherized the patient, to scrape and scrub such wounds thoroughly with a mail-brush and soap-suds before using the antiseptic solution. This double proceed- ing removes or destroys all germs that may exist in the wound. Injuries received from machinery almost always need such treatment, because of the dirt and grease ground into the tissues at the time of the accident, or upon the patient's skin before the receipt of injury. After such wounds have been made germ-free, they should be sutured as operative wounds, and provision made by catgut strands or drainage-tubes for the escape ºf serous and other fluids which may exude. The conversion of such acci- dental Wounds into aseptic wounds by these measures is an essential first step in treatment. Wounds subjected thoroughly to this treatment usually unite by first intention. If this is not the case the granula- tion process goes on so rapidly that the patient's convalescence is com- 120 MO DE OF REPAIR AND TREAT MENT OF WO UN DS. paratively short. In former times it was considered impossible for such wounds to heal without suppuration, which was accompanied in many instances by more or less violent constitutional implication. We now know that the wounds were, in those days, really complicated by infec- tion from pyogenic and putrefactive germs. After thorough cleansing with sublimate or betanaphthol solution, and after all foreign bodies have been picked out with sterilized forceps, the bruised and lacerated parts should be adjusted and kept in place by sutures, if this can be done without causing tension or interfering with the escape of the fluids to be subsequently secreted. Much damage is often done by making nice approximation of such wounds and providing no escape by drainage-tubes and counter openings for the serum and pus which may arise in a few hours and cause tension and pain. If the fluids thus secreted find no free avenue of escape, burrowing of pus and septic conditions are liable to occur. Parts that cannot readily be brought together should be allowed to gape. Union by granulation is the method of healing in these wounds. Con- tused and lacerated wounds are usually followed by sloughing of their ragged borders; but it is improper to cut away anything more than the edges at the first dressing, since it is not possible to determine what parts are actually devitalized. The ordinary gauze dressing should be used. Thorough drainage of deep and irregular wounds by tubes, strings of rubber, or horsehair, is important. When the sloughing stage has given place to the granulation stage the resulting ulcerated surface is treated as an ulcer. If abscesses are liable to form, provision must be made for draining the deep parts by drainage-tubes, incisions, and washing out with syringes or by hydrostatic pressure. When the injury has caused complete devitalization, amputation must be done as soon as reaction from shock has occurred. If the soft parts are completely stripped from the bones amputation may be demanded, even when the Osseous tissues are intact, because of the danger of acute traumatic gangrene. If attempts have been made to preserve crushed limbs and rapidly spreading gangrene supervenes, amputation is usually to be done promptly at a high point of the limb. *. In incised wounds an attempt should always be made to secure union by first intention, because thus time is saved, the scar is less disfiguring, there is no drain from the system as when suppuration occurs, and there is less chance for septic complications. If the effort fails union occurs by granulation, as in lacerated wounds. In lacerated and contused wounds union by first intention is, from the nature of the injury, almost impossi- ble. After arrest of hemorrhage, removal of foreign matters, and the production of an aseptic condition in incised wounds, accurate adjustment is to be obtained by sutures of catgut, silk, or wire; or in small wounds by a layer of gauze or absorbent cotton glued to the skin, by collodion. About the face the latter dressing is sometimes preferable because a scar is left by sutures. The transparent gauze allows the surgeon to see that the wound is evenly apposed, and any unexpected serous or purulent discharge soon leaks through the meshes of the tarletan and is not shut in by the dressing. In other places than the face I prefer sutures, because even deep wounds can be apposed along their entire surfaces by buried catgut sutures applied to each successive layer of tissue. There is no ob- jection to the minute points of scarring from sutures except on the face. I always use sutures for the scalp. The application of interrupted and twisted sutures and of the collodion gauze dressing will be described in T R E A T M E N T OF W O U N ID S. 121 the chapter on Minor Surgery. I will merely repeat at this point the caution to students that there is a tendency to apply sutures too tightly. Mere approximation of the edges of the wound is what is desired. Any marked puckering is a serious fault. Catgut sutures stretch a little after tying and can be drawn tighter than wire ones. Punctured wounds when made with a sharp instrument require treat- ment like incised wounds; when made with dull instruments, such as car- penter's nails, they are practically lacerations. If they are penetrating wounds there will probably arise inflammation of the lining membrane or viscera of the cavity opened. This will demand treatment directed to the special lesion. The removal of the foreign body is often difficult in the case of punctures. If withdrawal with forceps is impossible a free incision will be required, especially if the vulnerating body is buried in the tissues and invisible. This should usually be done at once, and par- ticularly when the foreign body was probably covered with dirt and is especially liable to cause septic infection. The incision adds little or noth- ing to the gravity of the injury, may result in detection of the foreign body, and even if unavailing gives free drainage and lessens the dangers of erysipelas and other complications frequent in punctured wounds. A simple or an electromagnet has been found serviceable at times in re- moving chips of iron after lacerations or punctures of the eyeball. It is almost impossible to render a punctured wound aseptic without enlarging it; hence it is often good policy to increase it in order to sterilize it and prevent the occurrence of cellulitis or gangrene. Poisoned Wounds are usually punctures, since stings of insects, fangs of reptiles, and points of knives are usually the vulnerating instruments. Any form of abrasion or wound of the skin may be inoculated, however, and at times simple maceration of the skin with poisonous fluids in loca- tions where the integument is thin is sufficient. The wounds made by insects are comparatively unimportant in this country. It need only be said that if the sting remains in the wound it should be extracted, and lead water, sublimate solution (1 : 1000), water of ammonia, or spirit of camphor applied. Bites from insects with poisonous saliva should be managed in the same way. Any subsequent inflammation should be treated on general principles. Venomous snake-bites are usually accompanied by rapid and multiple interstitial hemorrhage, caused by an interference with the coagulability of the blood and disintegration of the vessel walls, due to the poison; paralysis of respiration and the spinal centres; and locally great swelling and vesication. The profound prostration or collapse is accompanied, however, with unimpaired intellection. Death occurs in an hour or so if the amount of poison is large, but in other cases may be delayed several days and occur through the depressing influences of gangrene and sup- puration. Many constitutional remedies have been vaunted, but there is no positive evidence in favor of any except alcohol, which should be given freely, but not indiscriminately. The intravenous injection of am- Imonia has been recommended, but its value is not yet established. The local treatment is important, and consists in immediate free excision of the Wound and surrounding tissues, the application of a tight ligature to the limb. above the wound to prevent venous and lymphatic absorption, sucking or cupping the wound left by the knife to extract the poison, and cauterization with equal parts of carbolic acid and alcohol. . Permanganate of potash freely injected into the wound and surround- *g tissues is serviceable in destroying the poison and should always be 122 MO DE OF REPAIR AND TREATMENT OF WOUNDS. used if obtainable. Nitrate of silver is valueless as a caustic, as, indeed, it always is when a tissue-destroyer is desired. The so-called intermit- tent ligature is a rational measure. It is merely a tightly constricting band, applied at the cardiac side of the wound and relaxed momentarily at intervals in order to allow the poison to enter the general circulation slowly and in divided amounts. This gives the surgeon a better oppor- tunity to counteract the effects of the poison and obtain its elimination than when the venomous material is suddenly absorbed in full amount. The poison is a chemical, not a microbic, one. It contains, according to Mitchell and Reichert, two albuminous poisons, called by them venom peptone and venom globulin. With the venom are introduced into the wound many bacteria, which are the agents and causes of the putrefac- tion which so rapidly occurs after snake-bites. Inoculation with the fluids of diseased or of decomposing animal tissue at times causes serious poisoned wounds. Malignant pustule, or charbon, contracted from cattle suffering with murrain, and glanders, or equina due to inoculation or infection from horses having this affection, are the most important forms derived from the lower animals. These affections are due to microörganisms and the ptomaines developed by their growth. I omit the discussion of hydrophobia here, because all pathologists are not agreed as to its being due to inoculation. It will be considered under Diseases of the Nervous System. Malignant pustule is especially found in tanners and butchers and is characterized by a vesicle at the point of inoculation, which is soon fol- lowed by violent inflammatory complications, such as angeioleucitis, cellu- litis, and gangrene. The degree of asthenia accompanying this car- buncular inflammation is profound and shown by its usual symptoms. The affection is due to the presence of a vegetable organism, the anthrax bacillus, contained in the blood and other fluids. The treatment consists of excision, or free incision, followed by thorough cauterization with cor- rosive sublimate or carbolic acid. Saturating the cellular tissues with injections of iodine has been considered valuable. Stimulant, supportive, and anodyne remedies internally administered are required. Free in- cision through the swollen and infiltrated tissues involved are indicated, even after the early stages. Glanders is another infective or mycotic disease, and is characterized by asthenia and by multiple indurations and ulcers of the surface, in- flammation and suppuration of the salivary glands, and profuse nasal discharge; though the last symptom is not always prominent in the dis- ease in man. The treatment should be conducted on general principles, as there is no special remedy for the condition. The prognosis in malignant pustule and glanders is unfavorable in the majority of cases. The term dissection wound is applied to injuries received during opera- tions on dead, and sometimes on living, bodies. They occur also in butchers, fish-dealers, and others whose occupation causes them to handle dead animals. Many wounds so received act merely as similar injuries inflicted under other circumstances; sometimes there is an additional amount of inflammation, as if the animal fluids irritated the part ; but occasionally a most virulent form of local inflammation occurs, and is accompanied by grave constitutional symptoms of blood infection. Persons whose previous health is poor suffer more frequently from such wounds than do other persons whose tissues have more resistence to in- fectious influences. These disastrous symptoms appear to be due to a T B E A T M E N T OF W O U N ID S. 123 specific poison generated in the cadaver a short time after death, or per- haps before death, which seems to be destroyed by the advent of marked decomposition. Cases of death from peritonitis, erysipelas, and pyaemia are more likely than others to cause such dissection wounds. These wounds owe their virulence to microörganisms or the chemical products of such organisms. They are, in fact, Septic wounds. There is a complete, or almost complete, protection afforded by pre- serving cadavers with zinc chloride, as is done in our Philadelphia dis- secting-rooms. It is important to recollect that the poison appears at times to infect the pathologist, who is making an autopsy, through the hair-follicles and unbroken skin of the hands, especially if they are im- mersed in the fluids of pyaemic pleuritis or peritonitis. The symptoms of a dissection wound, if of the ordinary variety, are those of an acute inflammation about a wound—viz., pain, swelling, inflamed lymphatic glands, fever, etc. Quite frequently suppuration occurs. In the more serious form a vesicle appears, after the lapse of a couple of days, at the point of puncture, and is followed by erysipelatous inflammation, angeioleucitis, rapid involvement of the cellular tissue, Sup- puration, sloughing, and septic symptoms, as shown by rigors, fever, colliquative sweating, and rapid prostration of the vital powers. Those cases seem to be worse in which inflammation of the lymphatic glands occurs before active inflammation of the wound. . The treatment consists in ligation above the wound to prevent absorp- tion, excision and cupping to get rid of the virus, and cauterization, prob- ably best effected by zinc chloride, corrosive sublimate, or carbolic acid. If, however, septic symptoms occur in spite of these precautions, quinia, alcoholic stimulus, anodynes, nutritious food, and supportive agents must be given and the wound treated by incisions and antiseptic washes. It S said that the spreading inflammation may at times be arrested by a blister applied around the limb, above the wound, as soon as the red lines indicating inflammation of the lymphatic vessels appear. Smearing the surface freely with mercurial ointment is often beneficial in these and other cases of angeioleucitis and phlebitis. Gunshot Wounds.-Gunshot wounds are injuries produced by the explosive force of gunpowder confined in firearms. They may, therefore, be caused by the powder alone, by the projectiles discharged, by pieces of clothing or splinters of wood given motion by such missiles, and by portions of weapons shattered by explosion. Gunshot wounds partake of the nature of contused and lacerated wounds, and hence are often fol- lowed by sloughing. When fractures are produced they are almost in- Variably open, or compound and comminuted. Cannon balls crush and pulpefy the parts struck. The wind caused by a passing ball does not and cannot produce a contusion, as was formerly supposed. In injuries so attributed the elastic skin has escaped injury, though actually struck. The wound made as the missile enters the tissues is called the wound of entrance, that made as it leaves the part, after traversing it, is termed the Wound of exit. The wounds of entrance and exit, especially if made by a projectile travelling with a comparatively moderate velocity, differ in *ppearance. The former is small and has depressed and regular edges, stained, perhaps, with grease and powder. The wound of exit has everted, Tagged margins, not stained, and is much larger than that of entrance, because. the skin has no external support when it receives the impact from within. Conical bullets discharged by rifled arms travel with such velocity that these distinctions are not always present. 124 MODE OF REPAIR AND TREATMENT OF WO UN DS. A bullet may traverse the tissues in a direct line, be deflected by bones or fascias, or be split against a bone and make several openings of exit. Instances are recorded where the bullet has taken a circular course and been found imbedded near the wound of entrance. Portions of clothing or wadding carried into the wound act as complications. Small shot fired at short range, say a foot or two, will make a single wound of entrance because there has been no scattering. Powder alone may, if discharged near the skin, produce a serious injury. In any event, if unburnt powder enters the skin there will be permanent discoloration like tattooing, unless the grains are discharged by suppuration or removed by the surgeon. It is unnecessary to speak here of shock, hemorrhage, and the other symptoms of gunshot wounds, since they correspond with injuries of similar gravity produced by other vulnerating agents. The treatment consists in removing the foreign body as soon as reaction is established, provided it can be done without seriously increasing the danger. The injury has been produced by the entrance of the projectile, and its passive residence in the tissues does not do sufficient harm to per- mit great risks to be taken for its removal. Bullets, especially if smooth, often become encysted and may remain many years without causing trouble. Still, the extraction of the ball, fragments of wadding or cloth- ing, and splinters of bone hastens the cure by lessening the danger of septic inflammation and suppuration, and at the same time gets rid of the possibility of remote inconvenience from encysted bodies. Hence, the bullet should be extracted, if it can be done either through the opening of entrance, which seldom is possible, or by a counter-incision. Of course if the wound of exit proves the escape of the entire bullet, and no foreign material lies in the wound, these measures are unnecessary. The wound should be made aseptic by cleansing, by irrigation with sublimate or betanaphthol solution, by counter-openings and drainage, and should be dressed with antiseptic gauze. Gunshot wounds, in which nothing except the bullet has entered the tissues, are often aseptic, probably because the missile has been sterilized by the heat generated in its flight. Much harm is often done by infecting such aseptic wounds by means of probes and fingers. Unless the examina- tion is aseptically performed, it had better be omitted, and the wound dressed with antiseptic gauze until a proper examination in skilled hands is obtained. To determine the course and position of the ball careful probing with an aseptic finger or metal probe is proper. When the opening involves the abdominal, cranial, or thoracic cavity, it is usually justifiable to make a free incision under rigid asepsis and explore the contained organs. This important topic will be discussed under injuries of the brain and viscera. In abdominal wounds immediate exploratory operation is usu- ally demanded. In cranial and thoracic wounds delay in or abstinence from operation may be proper. It is always well to examine the surface of the body on the opposite side, for the projectile may have passed across and be lodged under the skin, whence an incision will liberate it. For probing or examining the wound the patient should be placed in the position occupied when shot, to get the muscles and bones in the same mutual relation. The probe should be slightly bent at the tip to enable it to follow tortuous passages more readily as it is delicately inserted and turned about in the hand of the surgeon. The probe of Nélaton, which has a roughened porcelain T R. E.A.T MENT OF WO UN D S. 125 tip, may be serviceable, because it becomes marked by contact with the leaden ball and thus shows that the hard mass touched is not bone. The electrical apparatuses for determining the location of bullets are prac- tically valueless. When the ball has been found, attempts at extraction are to be made with the various forms of bullet-forceps and extractors. The incision may be freely enlarged if necessary. Unburnt powder about the face and hands is to be removed by patient picking with a small knife, or by cutting out little disks of skin with an instrument like a bunch. | Another method is to prick the skin with a needle dipped in croton oil or other irritant, which causes suppuration and leaves only minute white scars instead of the blue powder marks. When extraction has been accomplished or the attempt found fruitless, the wound is to be managed on the general antiseptic principles previously discussed. Thorough drainage by tubes or counter-incisions is resorted to according to indications. Immobilization with gypsum bandages over the antiseptic dressings will aid in protecting the injured bones from undue motion, if gunshot fracture exists. Amputation may be required for gun- shot injury if the bones are greatly shattered, large vessels or nerve-trunks destroyed, joints freely exposed with comminution of bones, or if rapidly spreading mortification is threatened. Primary amputations are usually preferable in such cases to secondary operations. Excision may at times be available in joint injuries or in gunshot fractures of the shafts of long bones. C H A P T E R X. PRACTICAL SURGERY AND ANAESTHESIA. INSTRUMENTS.—The instruments of the surgeon are innumerable, but those ordinarily required are few in number and simple in construction. Knives, forceps, scissors, hemostatic forceps, saws, needles, probes, and grooved directors are indispensable for the performance of surgical opera- tions, and undergo many modifications for special purposes. Certain operations demand additional instruments of peculiar character, such as the trocar, catheter, and syringe. A knife with a markedly convex or bellied edge is technically called a scalpel, while one that has very little belly and is nearly straight is termed a bistoury. WL \ WºW Z_S,SKYNS Scalpel with aseptic hollow metal handle. Scalpels are usually too convex, and are satisfactory only when a large flap of skin is to be dissected up. A knife nearly straight, partaking, therefore, of the character of the bistoury, is the best form and answers equally well for incisions, dissections, and opening abscesses by trans- fixion. Fº º- Q,\ \\\\7 SSQNS Bistoury with aseptic hollow metal handle. The edge of a knife is tested by drawing it from heel to point across the free border of a finger nail, for by this manoeuvre any notches will be apparent. Its keenness is proved by the ease with which it will cut when the edge is gently pressed upon the skin of the finger. The sharp- ness of the point is tested by the thrusting it through a piece of kid or gold-beaters’ skin stretched tightly over a ring. This little drum gives out a distinct sound at the time of puncture if the point of the knife is dull. Hemostatic forceps have a lock and are used to compress wounded vessels during the various steps of an operation, so that the surgeon need not be delayed by ligating bleeding points. In truth this temporary compression is often all that is needed; for small vessels soon become per- manently sealed and when the forceps are removed require no ligature. Large vessels should be tied before the hemostats are removed. Straight needles with the point ground on three sides, such as are used by glovers, are nearly always preferable to those curved near the point. I N S T R U M E N T S, 127 They penetrate the tough skin more readily and enable the surgeon to direct the point more certainly. FIG. 40. G.TIEMAN!!! 9, UO (EE-ſºº -- - - --- - - •ºr-zerº---------- E: ------- Glover's or bayonet-point needles, enlarged. A needle fixed in a handle and having an eye in the point is often useful. The sharp hook employed for drawing out the ends of divided vessels is called a tenaculum. It has been supplanted to a great extent by the hemostatic forceps. Probes should always be firm, but sufficiently flexible to allow the operator to bend the end slightly before beginning to explore a sinus. The slightly curved extremity will follow more readily the tortuosities of the channel, when the probe is rotated in the fingers.

Moist or dry heat is the only perfect sterilizer of instruments. They should always be washed perfectly clean after operation. Just before use they should be heated to at least 212° F. and kept at that temperature for ten or fifteen minutes. This may be done by boiling in water, by steam, or by baking in an oven. The handles should be smooth and of metal and not cemented, since cemented instruments are damaged by heat. All unnecessary complications and crevices should be avoided. Copper boxes with dust-tight lids are convenient receptacles in which to keep, bake, and transport instruments. FIG. 42. * º º | º: §§ Šºº. º #. * ſº :ań º : º º SJ; § | º § | º . Copper boxes for sterilizing instruments by baking. INCISIONS.—The knife should always be held delicately though firmly. The most common position of the knife for making incisions is that assumed when one uses a pen, though in dissecting up large flaps the surgeon will often hold the knife as if it were a fiddle-bow. Occasion- ally, as in amputations, the large handle is firmly grasped with the entire hand. When an incision is to be made the fingers of the left hand should support the skin at the point where the knife is to be entered, the surgeon then thrusts the point into the tissues perpendicularly and, immediately depressing the handle of the knife, cuts with the edge until the incision is sufficiently long; he should then, in order that the tissues may all be completely divided to the very end of the incision, elevate the handle and bring the knife out perpendicularly. Incisions should be sufficiently large to expose the parts and should be made with decided strokes of the knife. Nothing discloses the inefficient surgeon so much as small, button-hole like incisions, made by picking with the point of the knife. When possible, incisions about the face should follow the cutaneous creases that the scars may be as unnoticeable as possible. Oblique division of the skin causes slight scarring, and curvi- linear incisions are less noticeable than straight ones. In making incisions over large vessels or important organs the grooved director is to be pushed under the successive layers of tissue before the knife is used to divide them. This does not apply to the skin incision. ANAESTHESIA. For trivial operations, such as opening abscesses and removing small tumors, local anaesthesia is sufficient. It is induced in one or two minutes by applying a lump of ice or a mixture of ice and salt to the skin; by blowing ether, rhigolene, or other refrigerating vapor upon the surface with an atomizer, or by employing cocaine hydrochlorate. A NAB, S T H E S I A. . 129 Local anaesthesia obtained by the use of aqueous solution of hydrochlo- rate of cocaine is eminently satisfactory. A twenty grain solution of this salt in water painted upon a mucous membrane with a camel's-hair pencil, or dropped upon it from a medicine dropper, will produce local anaesthesia in about three minutes and will permit the performance of any minor opera- tion without giving the patient pain. If the application first made does not produce insensibility to pain in the part to which it is applied, a repeated application may be made in a similar manner. The anaesthesia thus produced lasts a number of minutes. It is important that the part to which the anaesthetic is applied should not be alkaline in reaction, since alkalinity of the surface interferes with the anaesthetic power of cocaine. Local anaesthesia cannot be produced in the skin, as in mucous mem- branes, by merely painting or brushing the surface with the solution, except for operations made upon very thin skin, as that of the eyelids. For cutaneous operations of a superficial character it is sufficient to inject the cocaine into or under the skin by a hypodermic syringe. From five to twenty minims should be introduced by one or two punctures. If more perfect local anaesthesia is desired, as for the removal of small tumors, the solution can often be incarcerated in the part, into which it has been injected, by retarding the venous return from the cocainized area by means of a ligature or a rubber ring. If an operation is to be made upon a finger or upon the penis, for example, the anaesthetic will last longer and prove more effective if it is incarcerated at the seat of operation by tying a piece of tape or placing a rubber band around the base of the member before the hypodermic injection. If an operation is to be made upon the eyelids or upon very thin skin, but not at a very great depth, a sufficient degree of painlessness can be obtained by simply painting the thin skin with the solution in very much the same manner as is done in operations on mucous membrane. In all such instances the surface should not be alkaline, else the anaesthetic power of the drug will not be exerted. It must be remembered that death has occurred from cocoaine poisoning. It is best, therefore, to avoid the toxic affect by not using a solution stronger than twenty grains to the ounce, and it is wise seldom to use more than twenty minims at the most, unless the drug has been incarcerated. Then after operating the surgeon can by intermittent relaxation allow it to enter the system gradually. The passage of urethral bougies and instru- ments of a similar character may be rendered quite painless by injecting the urethra with cocaine. When used upon the eye in large quantity and in too strong solution it occasions opacity, temporary however, of the Cornea, and may, therefore, possibly do harm if it is not used with proper caution. For the production of general anaesthesia in surgery ether is preferable to any other agent at present generally employed. Chloroform is much more dangerous. This is a sufficient cause for the abolition of its use. Its claimed advantages over ether are considerably overrated because of the improper methods in which ether is often given. Nitrous oxide is not a good anaesthetic for protracted operations, requires bulky apparatus for its administration, and in short operations can readily be substituted by local anaesthesia or the primary aniesthesia of ether. Rapidly repeated deep inspirations continued for a minute or so will Produce insensibility to pain (analgesia) for slight operations, though the Sensibility to contact is not obliterated. This effect may be utilized in 9 130 P R A CTIC A. L S U R G E H Y A N D A N AE S T H E SIA . surgery, but it and anaesthesia from nitrous oxide are used very little outside of dentistry. Before etherizing a patient the surgeon should examine the kidneys, heart, and lungs. The presence of disease in one or all of these organs should not deter one from the administration of ether when necessary for a painful operation; but the knowledge of its existence renders one exceedingly cautious, and protects him against the verdict of carelessness in the event of dangerous symptoms or a fatal result. Anaesthesia is always a dangerous condition, and requires the undivided attention of an experienced assistant. Death has occurred not infre- quently from etherization and often from chloroform anaesthesia. The patient’s stomach should be empty, lest vomiting occur during or after anaesthesia. Hence, he should fast for four or six hours prior to etherization, and it is even better if no solid food has been taken since the previous day. A hypodermic injection of morphia (gr. # to gr. 4) and atropia (gr. Hºw to gr. ſº) should be administered about fifteen minutes before inhalation is begun. This renders anaesthesia quieter, more rapid, and more safe. It is not an absolute essential but is very judicious. All clothing restricting deep inspiration must be removed or loosened. It is important to insist upon women unfastening their corsets and the skirts tied about the waist. Do not trust to the assertion that their clothes are not tight. False teeth and pieces of tobacco must be removed from the mouth, because of the danger of their falling backward into the fauces and obstructing respiration. The patient is usually placed in the recum- bent position, unless the operation is about the mouth or nose, when the semi-recumbent posture is better, as it prevents the blood flowing back into the pharynx. The semi-recumbent or sitting posture is not justifiable during chloroform inhalation. In operations upon the nose and palate it is often better to have the patient lying on his back with the head so bent backward that the palate is lower than the floor of the mouth. Blood is thus kept away from the site of operation and yet does not flow into the larynx, causing choking and coughing. When these preliminaries have been arranged the patient is shown how to inspire and expire deeply, and is encouraged to do so for a few moments. I sometimes tranquillize my patients and teach them to breathe properly by placing the dry towel over the face for a few seconds before adding ether. No inhaling apparatus is required. A cone of paper containing a loosely folded towel is a very satisfactory contrivance; but a small napkin or a handkerchief loosely folded and covered by a large towel so that the ether vapor cannot escape is usually preferable. The outer towel should cover the eyes of the patient, and no talking on the part of the bystanders should be allowed until insensibility occurs. The senses of sight and hearing should not be stimulated by any such disturbing influences. The ether vapor must be given in a concentrated form, and from one to two fluidounces should be poured on the napkin at first, that renewal may not often be required. When inhalation has once fairly begun the ether cloth should never be removed from the face, unless spasm of respiration or actual vomiting necessitates its temporary withdrawal. It should be held closely to the nose and mouth ; sufficient air will reach the lungs through the meshes and folds of the towel. The patient becomes ex- cited, the surgeon irritated, and the stage of etherization greatly pro- longed by the etherizer allowing a large amount of air to mix with the anaesthetic vapor. Frequently, indeed, I have seen the cloth taken entirely away from the face while additional ether was being poured on A N AEST H E SIA. 131 the napkin. This is mismanagement, for it allows the stage of excite- ment to be prolonged, and condemns the patient to a protracted anaes- thesia which increases the danger of subsequent bronchial irritation and cardiac depression. If the room is kept quiet, the patient previously taught how to breathe deeply, a full amount of ether poured on the towel, the eyes of the patient covered, and no air admitted to the lungs except that which passes through the towel, complete anaesthesia can be obtained in from three to ten minutes in nearly every instance. It is not safe to give chloroform in this manner. During the entire period of etherization the administrator must care- fully watch the respiration, color of skin, and pulse. The first two points demand especial scrutiny, but the changes in cardiac force, which can be most conveniently investigated at the temporal artery in front of the ear, must not escape examination. It occasionally happens that after a few inhalations have been taken a spasm of respiration takes place, evinced by absence of inspiratory effort and cyanosis of the face. This calls for the withdrawal of the ether for a moment, when a deep inspiration occurs, and no further symptoms of asphyxia are shown. If in the stage of excitation the patient struggles and cries out, the ether cloth must be kept closely applied, because access of air increases the excitement. The crying and shouting are desirable at times, because by the deep inspirations necessitated inhalation is more quickly accomplished. Retching as if vomiting was about to occur is an indication to keep up the ether. During complete anaesthesia vomiting does not take place. If, however, the stomach contents are regurgitated upward into the pharynx and mouth, the ether must be stopped until the fauces are cleared of materials that might pass into the larynx. The suspension of inhalation should be as momentary as possible. Sometimes the ether vapor causes an abundant secretion of bronchial mucus, which collects in the larynx and fauces and causes impeded respiration. This complication is met by clearing the throat with a finger introduced into the mouth, or by turning the patient on his face for a moment with his head hanging down over the edge of the operating-table. When the conjunctiva is insensible to touch with the finger, the muscular relaxation complete, and a tendency to stertorous breathing noticeable, the time for operating has arrived. The ether may then be withdrawn or only administered in sufficient quantities to keep up the anaesthetic state without inducing a continuance of loud palatal and laryngeal stertor. Stertorous respiration usually means that anaesthesia should not be pushed, since the patient is then insensible to pain. There is a primary anaesthesia lasting about a minute which is asso- ciated with muscular relaxation and occurs soon after inhalation has begun. This stage of etherization may be utilized for the performance of such operations as opening abscesses and extracting teeth. The re- covery from this anaesthetic condition is very prompt and unattended with the nausea and other after-effects of prolonged etherization. This primary anæsthesia or first insensibility of ether is not sufficient for other than minor surgical operations. It resembles to my mind the analgesic effects of rapid respiration, previously mentioned, more than true anaesthesia. . In all administrations of ether it must be remembered that its vapor is inflammable and so dense that it falls toward the floor; therefore all candles or other lights should be placed at a distance from the patient and at a higher level than the operating table. hen patients regain consciousness after etherization they occasionally 132 PRACTICAL SURGERY AND AN AST H ESIA. become very noisy and hysterical. The shouting can be stopped by pour- ing a little water into the mouth every time the patient opens it to cry out. This compels him to close his mouth to swallow. If the nostrils are closed by one hand of the attendant while the other hand administers frequent doses of water, the patient soon becomes too much occupied with Swallowing and mouth breathing to think of making further outcry. If dangerous symptoms, such as asphyxia, or cardiac failure, occur during the administration of an anaesthetic the inhalation must at once be sus- pended. If mucus or vomited matters produce interference with respira- tion they must be promptly removed. Tracheotomy might be demanded when ankylosis of the jaws or other causes interfered with proper clear- ance of the larynx. Imperfect respiration may be due to an effect of the ether on the nerve-centres. Pulling the tip of the tongue forward and far out of the mouth often aids the respiratory function, but artificial respiration and electrical stimulus may occasionally be required. In many cases dashing cold water in the face, slapping the cheeks with a towel dipped in water, or pouring a little ether upon the epigastrium is sufficient. Pushing the lower jaw upward and forward has been recommended as a valuable procedure. Heart failure producing anaemia of the brain is combated by inversion of the body, perfect muscular quiescence, and inhalations of nitrite of amyl. In addition atropia, digitalis, and perhaps ammonia should be given hypodermically in full doses to combat the toxic effects of ether. Experimental investigation in physiological laboratories seems to prove that alcohol is injudicious in the treatment of ether poisoning. It should, therefore, not be given in such cases. If this experimental evidence is accepted it is improper to administer alcohol before etherization to avert shock. Quinine, atropia, digitalis, and morphia are preferable. Persons addicted to alcoholic stimulation require more ether to induce profound anaesthesia than temperate ones, because they have become habituated to the effects of similar intoxicating agents. The administra- tion of the anaesthetic must be cautious, because the viscera of drunkards are frequently diseased. It is unwise to etherize a patient without assistance, because dangerous symptoms might arise from the anaesthetic or the operation, and the sur- geon would be unable to give efficient aid alone. A woman should never be etherized by a man unless a third person is present, since a charge of criminal assault might be made because of erotic dreams during the anaesthetic state. C H A P T E R XI. OPERATIVE SURGERY. PREPARATION OF THE PATIENT AND THE SURGEON AND MODE OF CONIDUCTING OPERATIONS. THE preparatory treatment of persons about to undergo operations that do not require immediate execution is important. Debilitated patients should be built up by food and tonic regimen; those of an opposite con- stitution may require more moderate diet than usual, purgation, and some restriction as to stimulants. Peculiarities of disposition and constitution should be studied by the surgeon, since the existence of the hemorrhagic diathesis, a tendency to delirium or any other marked habit of body might influence the choice of methods of operating. Encouraging words are of great value in sus- taining the spirits of timid patients. All patients, if placed in a hospital or removed from their homes, should ordinarily be allowed a day's delay in order to become accustomed to strange surroundings, nurses, beds, etc. If restraint of a limb in one position is essential to the success of an operation, it is well to keep the limb in that abnormal posture for a day or two that the weariness so caused may pass away. Menstruation if normal does not seem much of a contra-indication to operation, though the time between the periods should ordinarily be selected. Pregnancy is usually a proper cause of delay in operations of expediency. The seat of operation must always be rendered aseptic by shaving, so as to remove the fine hairs which may retain dust and germs, and by subsequent thorough scrubbing of the skin with soap and water. A second washing with a sublimate solution (1 : 1000) is then proper. Before serious ope- rations the patient should, if possible, be given in addition a full bath the evening previous. This is to avoid septic contamination from bac- teria on the skin. The umbilicus and the folds of the skin about the groins, axillae, and toes are especially apt to be overlooked in these cleansing processes. The secretions, epidermis, and dirt retained there are full of bacteria, as are the spaces underneath the nails of the patient as well as of the surgeon. A good light and a bright, cheerful day are important factors in se- Quring the best conditions for operative surgery. A patient should never be kept waiting by the surgeon after the appointed hour. Anxiety and suspense induce nervousness. I always endeavor to arrive before the time agreed upon so as to anticipate the worrying period. It becomes mecessary at this point to enter with more detail into the matter of asepsis and antisepsis. - By asepsis is meant absence of all vegetable parasites or microörganisms. The word, therefore, is employed to signify that the surgeon has used *Very effort to prevent the presence of any such organisms in the wound; and implies, therefore, the absence of such parasites from the surgeon's 134 O P E R A TIVE SU R G E R Y. hands, from the instruments used, from the dressings applied and from the surroundings. Asepsis then, or aseptic surgery, means that the pro- cedure is germ free. By antisepsis is meant that the manipulations are directed toward the destruction of all microörganisms which may be present. In the one case the endeavor is to obtain perfect freedom from pathogenic organisms; in the other case it is to destroy any pathogenic organisms which may be present in the wound, upon the hands of the surgeon, or upon the dress- ings. If absolute asepsis could always be assured, antisepsis would be unnecessary. It is because there are so many sources by which bacteria may get into a wound, even when done under the supervision of the most careful surgeon, that many of us prefer to use antiseptic precautions in addition to cleansing the skin of the patient, scrubbing the surgeon's hands, and sterilizing the instruments and sponges. In some cases the use of chemical agents may be deleterious because they act upon the patient's tissues in such a way as to produce irritation ; at least, such is the case when they are applied in sufficient strength to render their antiseptic properties valuable. For example, an ordinary solution of carbolic acid or corrosive sublimate can never be put into the peritoneal cavity without danger. It is also possible that frequent wash- ing of recent wounds with such solutions irritates the tissues and leads to greater exudation of serum after the lips of the wound have been ap- proximated than would be the case if the wound was not subjected to such irritation. As has been said in an earlier chapter, heat is the most perfect destroyer of vegetable fungi; therefore, instruments, sponges and dressings, which have been sufficiently heated are free from germs. If the instruments and sponges are kept in the water in which they have been boiled they can be used with impunity, provided that dust is prevented from falling into the receptacle. Such sterilized, or aseptic, water is far less irritating than water containing chemical antiseptics. The antiseptic solution most often used for washing the skin of the patient and for scrubbing the surgeon's hands is water containing corrosive sublimate in the proportion of 1:1000 or 1: 2000. This solution, how- ever, is too strong to be used for irrigating cavities, because if any portion of the fluid should remain, as it often will do, there is great danger of producing corrosive sublimate poisoning. This is evidenced by the occurrence of vomiting and bloody stools. Betanaphthol (1:2500) is preferable for washing out such cavities because it is a non-poisonous agent. Betanaphthol, however, is not as powerful a parasiticide as cor- rosive sublimate. Boiled water, or steam which has been condensed in clean receptacles, should be used for abdominal operations. Sublimate solution should never be used to sterilize instruments, because it tarnishes the steel and dulls the edges of cutting instruments. For such purposes a betanaphthol solution or a solution of carbolic acid (1: 40) should be employed. If the surgeon prefers he may boil his in- struments and let them stand in the water until it has sufficiently cooled to allow him to put his hands in it or until he is ready for their use. The vessels should be protected from atmospheric dust by covers. I, myself, prefer betanaphthol solution, as a rule, for instruments, because it does not irritate the skin of the surgeon's hands as do corrosive sublimate and carbolic acid, and because it is safer than boiled water as it is antiseptic instead of merely aseptic. The sterilization of instruments by baking in copper boxes has already been described. PR E P A R A TI O N OF T H E P A TI E N T . 135 When an operation is to be performed the instruments required should previously be put in trays containing sterilized water or antiseptic solu- tion, and these trays should be set upon a table without being seen by the family or patient. All sponges, sutures and dressings must be sterile. The patient's skin must be made aseptic by thorough cleansing, the surgeon's finger-nails cleaned and his hands and arms scrubbed with soap and made free from possible pathogenic germs, his clothing covered with a clean operating apron, and his sleeves rolled up to the elbow; just before operating his hands should be dipped in a sublimate solution (1:1000) for a couple of minutes and the patient's skin washed with a similar solution. Every assistant should know his duty and attend to it alone. And no loud talking or unseemly jesting should be permitted. The assistants whose hands are to touch sponges, instruments, and the wound must be as aseptic as the surgeon. No one else should be allowed to handle anything. Nothing, unless it is germ free, is permitted to come into contact with the incised tissues. An instrument which has dropped upon the floor or touched the bed clothes must be rejected until again sterilized. The surgeon must touch nothing that is not sterile, unless he sterilizes his hands again with an antiseptic solution or washes them in sterilized water before approaching the wound. He dare not put his hands into his pocket or scratch his head or face without endangering the patient's life by the possible conveyance of a single bacterium into the wound. It is, therefore, well to surround the seat of operation with steril- ized towels laid over the clothing or bed coverings. These may be baked towels or towels soaked in sublimate solution and dried. A table or firm bed is preferable to a reclining chair because more steady, and not so easily disarranged by struggles during etherization. The patient's body and limbs should be covered and not exposed to the chilling influence of the air. A skilful surgeon usually has the whole plan of the operation clear in his mind before starting, and proceeds to its completion by successive steps with confidence and without hurry. Where uncertainty of diagnosis exists, the plan of procedure may require modification as the condition is revealed ; but this is very different from the vacillating course of the man who undertakes an operation without knowing exactly what he expects to do and constantly appeals to the surgical spectators for suggestions. The occurrence of hemorrhage should be precluded by the use of the Esmarch elastic bandage, or by acupressure or digital pressure to the main arterial trunk. Much of the depression formerly attributed to shock was really due to hemorrhage occurring after injury or during operation. The surgeon should not, however, stop in operations to ligate the numerous little branches that bleed; for many of them will cease Spontaneously, and others can be controlled by hemostatic forceps, applied by the assistants, until the operation is completed. Then ligatures can be used. In operations about the face it is especially noticeable that Small vessels spurt very vigorously for a moment or so, but soon stop with- out ligation. In major operations, as for the removal of tumors for example, the most difficult points should be attacked first. Let the operator get under the mass, if it be a tumor, as soon as he has made his cutaneous incision. Then he knows what he has to meet, and having controlled the sources of hemorrhage and mastered the grave complications, he can dextrously and With facility complete the work of removal. 136 O P E R A TI W E S U R G E R Y . The principles or fundamental laws of operative surgery are: 1. Obtain the services of an etherizer who will not require you to super- intend the anaesthetic. 2. Take precautions to prevent hemorrhage, if the locality renders this possible. 3. After proper thought and consultation have the plan of operation clearly outlined in your own mind. 4. Have the patient, the instruments, yourself and your assistants abso- lutely aseptic. 5. Proceed systematically with the steps of the operation decided upon, and do not be led into a mixed operation by bystanders, unless unexpected developments in diagnosis occur. 6. Attack the greatest difficulties and dangers of the operation first. 7. Do not stop to tie any except large vessels, but let assistants apply hemostatic forceps, or make pressure with their fingers until incisions are completed. 8. When the operation is finished, stop hemorrhage and apply dressings. 9. Finally, remember that suppuration in an operation wound is usually, probably always, due to careless asepsis on the part of the sur- geon or his assistants, except in those instances where the operation is done on tissues already suppurating. CONTROL OF HEMORRHAGE. The prevention and management of hemorrhage during operations will be considered in the chapter on Diseases and Injuries of Bloodvessels. SUTURES. When a wound has a tendency to gape, and there is a probability that union by first intention can be secured by correct apposition of the edges, sutures are employed. They should not be used in contused and lacer- ated wounds, if tension is induced by adjusting the parts, or if the wound is not perfectly aseptic, and there is danger of preventing thereby the free escape of serum and pus. The suturing materials most commonly used at the present time are catgut and silk. Occasionally wire or wormgut sutures are employed. It goes without saying that these sutures must be rendered aseptic, in order that they may not induce suppuration or other pathological conditions in the tissues into which they are inserted. Wire and silk sutures are rendered aseptic by baking, or by soaking in a strong antiseptic solution. Catgut is prepared and then kept in an antiseptic Solution until it is used. I, myself, prefer catgut kept in alcohol, because the oily menstrua in which it is sometimes preserved make it disagreeable to handle. Anti- septic catgut and silk sutures and wire for suturing can be obtained from the instrument-makers. Surgeons often prepare the catgut sutures and ligatures themselves, by purchasing violin strings and rendering them antiseptic by some such formula as the following: Soak the catgut violin strings in oil of juniper wood for forty-eight hours, in order to remove the fat; then wash in alcohol, and store in fresh alcohol until required for use. It is best to thread the needles, which should be aseptic, before they and the gut are put in the antiseptic trays used at the operation; because the catgut, when taken from the alcohol, is somewhat stiff and shrunken, but when put in water becomes swollen and cannot, therefore, be threaded SU TU H. E. S. 137 through needles with ordinary eyes. Such catgut sutures will become absorbed by the tissues in which they are placed in from five to ten days, varying according to the thickness of the thread. If it is desired to pre- vent the absorption of the sutures at such an early period—as happens, for example, when tendons or bones have been sutured—it is proper to use chromicized gut. This is catgut rendered less absorbable than ordinary antiseptic gut by the addition of chromic acid to the Solution in which it is prepared. To chromicize catgut the following formula is a good one : After having soaked the gut in oil of juniper wood for forty-eight hours, wash it in alcohol and let it soak for forty-eight hours in a solution pre- pared according to the following formula: Carbolic acid, 1 part ; chromic acid, gºt part; water, 20 parts; catgut, 1 part. After standing in this solution forty-eight hours the sutures should be washed in alcohol, and then preserved in fresh alcohol. Sutures, or ligatures, prepared in this way will be absorbed in from ten to thirty days, according to the thickness of the thread. The thicker the thread the longer the time required for absorption. Since they are not absorbed in the tissues for many days, chromicized catgut sutures can often be used with advantage where wire sutures were formerly and are often still used. The advantage of catgut sutures, whether chromicized or not, is that the surgeon does not have to withdraw them after union has taken place, as is the case when wire sutures are used. Silk sutures are often cut and withdrawn by the surgeon, although they need not be when buried in the tissues, for they become encysted or absorbed. Sutures of silk upon the surface are, however, always with- drawn. The forms of sutures usually employed are the interrupted, the con- tinuous, and the twisted or pin suture. The quill suture is deservedly nearly obsolete. The interrupted suture is made by carrying with a needle a catgut, silk, wire, or wormgut thread across the wound, cutting it off and fastening the two ends by tying, twisting or clamping with per- forated shot. This is repeated at intervals along the wound. The twisted, or pin suture, is made by thrusting a steel pin through the lips of the Wound, which are then held in apposition by a silk or catgut thread wrapped around the ends of the pin and across the surface of the wound. The pin is left in position until union has occurred. The thread may be twisted about the pin in an elliptical or figure 8 manner, or a rubber band may be employed in its stead. FIG. 43. FIG. 44. º ;Ss Granny knot, which is never used in Flat or reef knot. (J. D. BRYANT.) Surgery. (J. D. BRYANT.) Interrupted sutures are best made with catgut, silk or flexible iron-wire and a straight needle. Occasionally a curved needle may be preferable. 138 O P E R A TI W E S U R G E R Y. In linear wounds the first suture should be inserted across the middle ; in irregular wounds the projecting points had better be approximated first. The needle should puncture the skin not nearer than about one-eighth to half of an inch from the margin of the wound, and be carried deeply enough to bring the entire depth of the wound-surfaces together. First tie of surgeon’s or friction knot. The second tie is like that of the flat knot. (J. D. BRYANT.) The ends of the suture should be fastened at one side of the wound by a flat or reef knot if silk is used, by a surgical knot if gut is employed, by twisting the ends or clamping them with shot if wire is employed. Sutures should be placed at intervals of one-fourth or one-half inch, and should never be applied tightly, since mere apposition of the edges is all that is required and swelling will probably increase FIG. 46. the tension. Sutures would be unnecessary if there º was in wounds no gaping, or tendency to motion from muscular movements. A sufficient number of sutures should be inserted to avoid gaping between them. This is better than placing them far apart and using adhesive plaster in the intervals, since adhesive can scarcely ever be sterile. It is a useless and dangerous agent in the treatment of wounds. Three to six days is long enough, as a rule, for sutures to remain, though in deep wounds and in positions where strain is liable to occur, the sutures, if of wire, may remain almost indefinitely. When Interrupted suture of Stitches are to be removed the wire should be cut silk, showing the lower close to the knot or twist, the long end bent over to stitch too tightly tied, the other puncture and the wire drawn through the (STEPHEN SMITH.) tissues in a curved direction by means of a forceps grasping the knot. If this is not done, a little hook of wire is left when the suture is cut, and pain is caused by drawing this through the tissues. Catgut sutures need not be removed, because the portion of the loop buried in the tissues is absorbed and the external portion finally falls away from the skin. Chromicized catgut requires from ten to thirty days to be absorbed; ordinary antiseptic catgut is absorbed in from five to ten days. The time in each instance depends largely on the thickness of the thread of gut. Silk sutures may be cut and withdrawn, or, if entirely buried, may be allowed to remain in the tissues; when they are either absorbed as are buried gut sutures or they become encysted. These processes only occur perfectly when the sutures and wound are free from germs. The twisted, pin, or hare-lip suture is especially serviceable when the wound is situated in movable tissues, as about the face, and additional support is desirable, and also where considerable hemorrhage is taking SUT U R E S. 139 place from the wound. The pins must be inserted rather deeply, carried transversely across the wound and brought out through the opposite edge of skin. The thread must not be applied too tightly. The sharp point of the pin is then cut off or guarded by a piece of cork. After three or four days, when union has occurred, the head of the pin is seized with forceps, the pin rotated and gently withdrawn. The thread is often left in place to afford support until it falls off under desiccating influences about the wound. A combination of the interrupted and twisted suture is sometimes judicious in wounds requiring support and accurate adjust- ment.

This form of suturing is used a good deal more now than in the days When suppuration of wounds almost constantly occurred. At that time and under those cir- cumstances the interrupted su- ture was convenient because One stitch could be removed for the evacuation of any pus which formed at the bottom } of the wound cavity. Now that Showing beginning and final knot of continued We have little fear of suppu- suture. ration occurring the continuous suture is preferable in many instances, because it is much more rapidly *pplied than the interrupted and because it brings the edges of the wound 140 O P E R A TIW E S U R G E R Y. into neater apposition. When the continuous suture is begun the end of the thread of gut is tied to the main portion of the thread after the needle has drawn it through the second puncture. The needle then carries the thread across the wound and through the tissues in the way shown by the illustration. The suture is ended, at the other extremity of the wound, by tying the end of the thread and the loop made by leaving the thread long in the stitch next to the last. This method is shown in the diagram. Buried sutures are stitches which are used to bring together tissues at the bottom of a wound, and which are subsequently entirely covered up by more superficial layers of muscle or fascia, or by skin. In closing large and deep wounds extending through different planes of muscle the surgeon should suture each layer of muscle and each layer of fascia step by step from the bottom to the surface. This hastens union, prevents the formation of pockets or cavities in which blood or wound secretions might collect, and restores most effectually the normal integrity of the parts. Divided nerve-trunks should be united by these buried sutures, severed tendons accurately approximated and muscular masses and fascial sheaths carefully reconstructed. Perfect asepticism is essential for success; cat- gut or silk sutures are to be employed for these purposes. In suturing tendons chromicized gut should be used, because ordinary gut is apt to be absorbed before the tendons unite, and because the strain upon the suture is often considerable. In all these instances the sutures are cut off close to the knots and are allowed to become absorbed or encysted. The peculiar method of passing the suture shown in the illustration is the best for tendons; other structures may be united by the interrupted or con- tinuous suture as seems best to the operator. t Diagram of suture of tendon. (ESMARCH.) The peculiar devices used for Suturing intestinal wounds will be de- scribed under Surgery of the Abdomen. DRESSINGs. The dressing which practically is used for all wounds, whether opera- tive or accidental, is gauze. This gauze is what is technically called in trade circles cheese-cloth or butter-cloth. It is a loose cotton mate- rial with open meshes and readily absorbs fluids. It can be bought from dealers in surgical supplies, either plain or impregnated with cor- rosive sublimate or betanaphthol in varying proportions, and is, in the latter case, properly called antiseptic gauze. Plain gauze is supposed to be perfectly free from germs, which, of course, it never is, unless previously subjected to high heat and kept in cans tightly sealed. Cheese- cloth can also be readily bought at dry goods stores, and after it has been washed in hot water containing a little soda and dried, it becomes a very cheap and effective dressing. This the surgeon must make aseptic for himself, by baking it in an oven and keeping it free from the slightest D R E S SIN G. S. 141 possible contamination with dust, or antiseptic by saturating it with a ermicide Solution. When the wounds are open and the gauze dressing comes in actual contact with the wound surface the secretions on drying glue it to the wound. A great deal of pain is therefore given to the patient upon the removal of such a dressing, unless it has been carefully soaked for some time with water, which must be sterilized to prevent infection. It is well, therefore, to cover open wounds with a piece of thin rubber tissue or oiled silk “protective” before applying the gauze dressing. If rubber tissue is used it should be cut full of slits or small holes with a pair of scissors, in order that the secretions from the wound may escape into the gauze and not macerate the tissues lying under the rubber, film. Evap- oration and percolation are more free through the oiled silk, which goes by the name of “protective,” than through rubber tissue, hence the former does not, as a rule, need to be perforated. If a wound has unfor- tunately become the seat of profuse suppuration the gauze will not adhere even when placed in direct contact with it. In wounds the edges of which are brought into actual contact by sutures there is no occasion for using “protective” under the gauze; the gauze may then be laid directly upon the wound itself. It must be understood, of course, that this rubber film or oiled silk must be thoroughly cleansed and rendered aseptic or antiseptic before being applied to the wound. It is perhaps unneces- sary to say that all drainage-tubes, whether of rubber or of glass, must in a similar manner be rendered aseptic or antiseptic before use. When a wound is dressed a large mass of gauze consisting of from four to twenty layers, varying with the degree of serous effusion which the sur- geon presumes will escape from the wound, must be firmly and evenly bandaged over the injured surface. It is absolutely necessary that the margin of the dressing should extend a considerable distance beyond the limits of the wound, in order that the wound secretions may not, by trav- elling between the skin and dressing, get beyond the edge of the latter and become infected with bacteria from the air, clothing or bandages before the surgeon repeats his visit. In such an event the organisms will develop in the bandages or portion of clothing soiled with the discharge and cause putrefaction and suppuration; the infection will continue along the path of serum made under or in the gauze, and finally enter the wound. It is important, therefore, that no such entrance shall be made through or under the dressing by such a track of albuminous fluid extending to infected objects outside. The bloody serous trans- udate, which takes place from the wound, usually occurs within the first few hours. It is, therefore, wise to change the dressing of large wounds and of wounds where there has been a great deal of secretion, within the first twenty-four hours, because of the possibility of such fluids reaching the surface at some part of the dressing not easily examined by the sur- geon. This second dressing will cause no annoyance or harm if it is done With the same attention to antiseptic precautions as is given to the first dressing. The hands of the surgeon and all instruments and dressings must be as carefully free from germs as at the time of the operation. After the second dressing no change is required until the fluid soaks through the gauze in the course of several days, or until pain in the Wound or a marked rise in the temperature of the patient shows that Some complication has arisen, and that the wound is not doing well. The drainage-tubes may often be removed at the time of the second dressing, unless suppuration has occurred, which condition, however, we do not 142 O P E R A TI W E S U R G E R Y . look for in aseptic wounds. If suppuration from any cause does exist in a wound tubes will be required, to give free vent to the pus. In small wounds where there is but little effusion a single dressing is often sufficient, and by the second or third day the wound will frequently be found cicatrized. This sometimes occurs at the second dressing of quite large wounds when that dressing is not made for two or three weeks. In my opinion the gauze should always be applied dry, because bacteria are much less liable to multiply in dry situations than in wet ones; hence a wet dressing seems to me to increase the possibility of microbic infec- tion, even when these dressings have been moistened with antiseptic solu- tions. I prefer gauze which has been made aseptic by baking, applied dry, or gauze which has been impregnated with sublimate solution and subsequently dried. Gauze which has been sterilized by baking is not very absorbent. A small amount of glycerine sprinkled upon it before it is baked makes it absorb fluids much more efficiently. When there is no wound and a poultice is desired to relieve pain it should be made of aseptic or antiseptic gauze, covered with oiled silk or rubber cloth to prevent evaporation. Poultices of flaxseed and similar material, are seldom used or desirable. In some small incised wounds a dressing of collodion and iodoform, or collodion and boric acid may be used instead of a gauze dressing; for example, after the removal of a small tumor of the face a little collodion mixed with iodoform may be painted over the edges of the wound in such a way as to make an impervious varnish, which keeps the wound free from germs. Sometimes this collodion dressing can be made a little stronger by laying a small portion of aseptic absorbent cotton upon the wound and saturating it with collodion and iodoform or with collodion alone. Boric acid or corrosive sublimate would probably answer as well as iodoform to mix with the collodion and would be less obnoxious in odor. The mixture is painted upon the part after the catgut sutures have been used. If corrosive sublimate is selected, not more than an eighth or a quarter of a grain should be mixed with a fluidounce of collodion. BANDAGES. Roller bandages are used by the surgeon for the purpose of retaining dressings in position, making pressure, and restraining motion. A bandage is a strip of muslin, linen, or flannel, varying in width from one-half inch to two or three inches and in length from three to ten yards. It is ap- plied smoothly to the surface by circular, spiral, and reverse turns, and should always make equable pressure and be firmly enough applied to its place during the ordinary movements allowed the patient. When a considerable amount of elastic pressure is required for pro- moting absorption, as in treating diseased joints and chronic ulcers, a bandage made of pure rubber is invaluable, though a flannel bandage will in some degree effect the purpose. The Esmarch apparatus, which consists of a rubber bandage for expel- ling blood from a limb and a rubber tourniquet for preventing its return during the time of operation, will be discussed under Diseases and In- juries of Blood vessels, where hemorrhage is considered. A B S T R A CT I O N OF B L O O D. 143 COUNTER-IRRITATION. When a mild form of counter-irritation is wanted, mustard plasters, tincture of iodine, water of ammonia, and similar agents, or dry cups, are applied to the skin; if vesication or blistering is desirable, cantharidal collodion, cantharidal citrate, or an iron disk heated by immersion in hot water is employed. More powerful revulsive agents are setons, caustic potassa, and the red-hot iron. The best form of actual cautery is the thermo-Cautery of Paquelin, which consists of a double metal tube with a hollow platinum end through which a current of benzole vapor is blown by compressing a rubber bulb. If the platinum portion is first moder- ately heated in a lamp, it can be raised to and maintained at a red or white heat by keeping a constant current of benzole vapor circulating within it. Paquelin’s thermo-cautery. This is an exceedingly convenient and manageable instrument. Ordi- nary cautery or soldering irons, heated in a furnace, answer the same purpose. The electro-cautery is usually inconvenient for the surgeon's use. The pain felt from the cauterization after the patient recovers from anaesthesia can be averted by painting the burned surfaces with undiluted carbolic acid before sensibility is regained. Counter-irritation is sometimes obtained by thrusting needles into the tissues—a method termed acupuncture. The needles may be arranged in * bundle and propelled by a spring, or may be introduced singly by the fingers of the surgeon. Additional irritation is induced, when necessary, by dipping the points in croton oil. $: ABSTRACTION OF BLOOD. Local abstraction of blood by leeches has been superseded, to a great $ºtent, by multiple punctures and scarifications with a sharp knife and by wet cupping. In both cases the flow of blood is encouraged by affu- 144 O P E R A T L V E S U R G E R Y . sions of hot water. General bloodletting is accomplished by opening a vein, usually at the bend of the elbow, or, when a sudden and powerful impression is required, by incising the temporal or radial artery. When venesection from the arm is to be performed, a bandage is tied around the arm above the elbow, sufficiently tight to prevent the venous return but not firm enough to prevent the downward arterial flow. The veins then become distended. The arm must next be made aseptic, after which the operator, selecting the median cephalic vein be- cause it is not in close relation with the brachial artery, steadies it with the thumb and forefinger of his left hand, and makes an oblique incision into it by transfixing it with the point of a bistoury. The incision must be a free one to allow the blood to escape in a jet. If the median cephalic vein is not large enough to give a good flow, the median basilic or any one that is prominent may be selected. It must be remembered that the brachial artery lies under the median basilic vein; but if the vein is transfixed laterally with the point of a knife and the incision made from within outward, there is no danger of wounding the artery. The old- fashioned spring lancet is much more dangerous, and is inferior to an ordinary bistoury for such an operation. The vein can be nicely steadied for the incision by passing a small acupressure or harelip pin through the skin and underneath the vessel. This is better than attempting to pre- vent its slipping away from the bistoury by means of the fingers. Phlebotomy should be done when the patient is in the semi-recumbent position. Removal of the bandage around the arm will stop the flow of blood, after which an antiseptic pad is placed over the wound and the limb kept comparatively quiet for a day or two. * Arteriotomy is performed by merely cutting down upon the pulsating vessel and making an oblique or transverse incision into its wall. When the amount of bleeding is satisfactory, the vessel should be completely divided and pressure applied; or ligatures may be put upon the ends of the artery. ASPIRATION AND TAPPING. Aspiration is the evacuation of fluids by means of a vacuum connected with a hollow needle or a canula, and is advantageous because it prevents the admission of air to the cavity from which the fluid is taken. Hence septic changes are avoided. The aspirator, as perfected by Potain, con- sists essentially of a reservoir which is connected with an exhausting pump and from which a tube passes to be connected with a hollow needle or a canula and trocar. Stop-cocks are provided to prevent the admis- sion of air to the tubes and reservoir or to the cavity to be tapped. When an abscess or serous collection is to be aspirated, a vacuum is created in the reservoir with the air-pump, and the needle introduced into the tissues. The vacuum chamber is then connected with the needle by turning a stop cock, and as soon as the point of the needle enters the cavity atmospheric pressure forces the fluid into the chamber. When an aspirator is not at hand, or when it is desirable to have less pressure than that induced by a vacuum, the principle of the siphon may be utilized by attaching a long tube to a trocar or hollow needle and carrying the end below the level of the patient. The hypodermatic syringe answers admirably for aspirating small cysts and abscesses, and is also of great value in determining the character of obscure swellings. The grooved exploring needle, so frequently used, is <º A SPI R A TI O N A N ID TA PPI N G . 145 far inferior to the hollow needle and syringe, and is never used by me for diagnostic purposes. Motion of the end of the hypodermic needle will often disclose a cavity, even if the contents are too viscid to escape through the orifice into the glass barrel of the hypodermic syringe. FIG. 52. gººse 2 ºº & Y. º N M3 M3 § § &N § § W w Öğ º § #! 3 º W3 fl § - § § & & Aspirator. When the entrance of air into the cavity to be evacuated is considered unimportant a trocar and canula are employed. In using a trocar the surgeon should make the parts tense by pressure with the fingers of the left hand, select a point free from veins or arteries and plunge the trocar and its surrounding canula through the skin with a sudden rotary thrust. As long as fluid flows freely enough to fill the entire calibre of the canula no air will enter. Such a free flow can be kept up until the . is nearly empty if pressure is made upon its walls by the surgeon's ngers. In many instances open aseptic incision is preferable to either aspira- tion or tapping, which are too often the resources of a timid and dilatory Surgery. They have, however, a legitimate field. 10 C H A P T E R X II. PLASTIC OR REPARATIVE SURGERY. UNDER the term plastic surgery are grouped those operations which have for their object the construction of absent parts, usually from the patient's own tissues, and the reposition or curtailment of parts displaced or deformed by accident or disease. - The word plasty is often used with a prefix to indicate the organ formed; thus, rhinoplasty means the reconstruction of a nose, cheilo- plasty the formation of a lip. Plastic surgery is called into play to overcome both congenital and acquired defects and deformities. Its objects, therefore, may be stated to be : To correct deformity due to imperfect foetal development, as harelip and cleft palate; to replace parts lost or deformed by injury or ulcera- tion, as in closing fistules or clefts, and reconstructing destroyed noses or lips; to relieve or prevent distortion from cicatricial contraction, as after burns and cervical abscesses and the removal of tumors requiring abla- tion of a large amount of integument; and to curtail organs rendered unseemly by abnormal growth, as in greatly hypertrophied nose or tongue, and in large and protruding ears. The structures used in constructive operations are especially skin and subcutaneous cellular tissue, though mucous membrane, which becomes somewhat like skin when removed to the external surface, muscle, peri- osteum, and even bone, are at times successfully utilized. The steps of a plastic operation are to be followed in regular succession and the plan of procedure should be clearly fixed in the operator's mind before he makes the first incision. The patient must be in good health, so as to be less likely to have erysipelas or ulcerative action attack the wounds made. When parts destroyed by syphilis are about to be reconstructed, it must be ascer- tained that no syphilitic manifestations have occurred for several months, since a recurrence of specific ulceration would destroy the success of the plastic operation and perhaps render future measures impossible. The operation should be rigidly aseptic. The successive steps are: Freshening the edges of the vacuity to be filled and obtaining one or more flaps if such are required; arresting all bleeding, since clots between the raw surfaces may prevent union by first intention; adjusting the parts in proper relation without tension and retaining them in apposition by sutures; closing the gap left by removal of the flaps, if such have been employed; dressing all the wounds anti- septically or aseptically, and preventing motion and frequent handling of the parts. In complicated reparative procedures it is often necessary to accom- plish the desired end by a series of operations, each one of which effects a result which affords a basis for subsequent measures. The time between any two operations may be weeks or months, for the secondary operation should not be undertaken until cicatrization and shrinkage have fully determined the condition gained by the primary one. M ET H O D S U S E D IN PLA STI C S U R G E R Y . 147 Sutures of catgut, plain or chromicized, of silk, and of wire are used according to the length of time their sustaining power is needed. In applying the sutures, doubling in of the edges of the flaps can be pre- vented by introducing the needle obliquely, so that the punctures on the inner surface are further from the margin than the external punctures. This causes the apposed sides to pout out a little at first, but the protru- sion disappears with cicatrization ; if not, it can be pared away subse- quently. A few deeply placed sustaining sutures may be advantageous in maintaining approximation when the plastic operation requires the union of large surfaces extending inward to a considerable depth, or buried sutures may be employed. The strain is thus taken from the superficial sutures, and rapid union of all portions of the wound is encouraged. Sometimes the support given by the pin suture makes it preferable to the interrupted or continuous sutures. Silk or gut sutures are sometimes employed between metallic ones to make very accurate apposition of thin edges. Their early removal or absorption, before it is safe to take out the deeper metallic sutures is not disadvantageous. The tongue-and-groove sutures of Dr. Joseph Pancoast is often a very excellent method of maintaining apposition in rhinoplasty and operations for exstrophy of the bladder. It consists in slipping the flap margin, which has been FIG. 53. bevelled, into a groove made by dissecting up the edge of skin surrounding the raw surface to be covered. Four raw surfaces are thus apposed. Wire or silk sutures are then applied, as shown in the diagram, and fastened over a perforated ** disk or a pad. It is easy to adjust the sutures Diagram of tongue and groove by having both ends armed with needles. suture. The gap left by the removal of the flap in plastic operations should be closed, if possible, by drawing the integument together, or by inserting a flap taken from the neighboring skin if it can be obtained from a site which will put the cicatricial tension in a less objectionable locality. If neither means is applicable provision should be made for healing by granulation. Often the tissue dissected away to make a raw surface for adhesion of the flap can be utilized for closing the hiatus left by the elevation of that flap. The various plastic procedures are included in the three methods of Operating which I shall term respectively the methods by displacement, by interpolation, and by retrenchment. Under the displacement method are included operations done by simple approximation and by sliding; under the method of interpolation are classed procedures accomplished by transference and by transplantation. The relations and characteristics of these modes of operating will be Seen by the schedule. Methods used in Plastic Surgery. Disrºacúſūnt—stretching or sliding of tissues. 1. Sºmple approvination after freshening the edges, as in harelip, vesico-vaginal fistule, Y and notches caused by tearing out ear-rings. II. Sliding into position after transferring tension to adjoining localitics, as in V-shaped incision for ectropium and cicatricial contraction of joints after burns, and in linear incisions to allow stretching of skin to cover large wounds and to relax contracted parts. 148 P L A. STIC O R. R. E. P. A. R. A.T. I W E S U R G E R Y . INTERPOLATION.—borrowing material from adjacent regions, from a limb, or from another person. I. Transferring ſlap with a pedicle." A. Putting in place at once. 1. By rotating flap on the pedicle in its own plane through one-ſourth or one-half a circle, as in making upper eyelid or nose from ſorehead. 2. By twisting flap on its pedicle, as in making side of nose from lip. 3. By everting flap entirely so that raw surface is uppermost, as in covering exstrophy of bladder by a scrotal flap. 4. Superimposing one flap on another which has been everted. This is done where a thick wall is desirable, as in closing the front of an exstrophy of the bladder. 5. By jumping, or carrying flap across a bridge of skim, and fixing only its end to the part to be repaired. When the flap has become attached the pedicle is severed. This manoeuvre is rarely employed. B. Putting in place gradually by successive migrations, by same manoeuvres as when the flap is placed at once in its permanent position. This method is not very commonly needed, but may be valuable whem there is nothing but cicatricial material in the immediate vicinity of the part to be repaired. II, Transplanting without a pedicle. a. By carefully suturing or fixing in the gap areas of tissue recently dissected from distant regions, or taken from the lower animals; such as re- placing the bone button after trephining, inserting portions of merve- trunks in wounded nerves, etc. b. By skin-grafting with small pieces or large shavings of skin. This is the manoeuvre of this class that has been followed by the greatest success. As it lessens cicatricial contraction it may be advantageously used at times in plastic operations that necessarily leave surfaces to heal by granulation. Skin from the frog's abdomen may answer well. c. By readjusting finger-tips, ears, and noses recently completely severed by injuries. RETRENCHMENT—removing superfluous material and causing cicatricial contraction. I. By cutting out elliptical or semi-elliptical pieces of tissue, as in ptosis, cystocele, and prolapse of the rectum. II. By cutting out triangular or wedge-shaped portions of tissue, as in closing the vaginal aperture, decreasing the size of a lip, ear, or nose, and separating webbed fingers. Retrenchment is often valuable because it decreases the relative size of features; thus, if a nose has been partially lost the upper lip appears too large, and its diminution will render the deficient nose less noticeable. When material is taken from the prominent feature, and especially if added to the other the normal proportion is nearly reëstablished and de- formity greatly concealed. To secure success in plastic devices certain precautions should be observed. In the first place, the patient should be in good general health and free from irritation or inflammation about the seat of the proposed operation. In transferring or transplanting it is essential to select normal integument for the flap, because cicatricial tissue is almost sure to slough if dissected from the Subjacent structures. Approximation and sliding operations, however, may be successfully performed with cicatricial tissue, because these methods interfere very little with the vascular supply from beneath. All flaps should be made large, thick, and with a good vascular supply through a wide pedicle. As soon as the flap is dissected loose, it shrinks and becomes paler and cooler. Hence, it should consist of skin and plenty of subcutaneous tissue, because thick flaps contract less and are more vascular. It should be made about one-third larger in area than * When a flap is borrowed ſrom the arm or hand there is less necessity for rotating and twisting than when it is taken from the neighborhood of the organ to be constructed. The latter is generally the preferred method, however, because less irksome to the patient than the former with its constrained posture. M ET HO D S USE I) IN PLA STI C S U R G E R Y. 149 the space to be filled and should be allowed to cool as little as possible by being placed in position as quickly as practicable. For the last two reasons I consider it preferable to freshen the edges of the part to be repaired before making the flap. This is especially true in transplanting flaps. }. is sometimes well to cut a diagram of the flap out of paper or cloth, and mark a similar outline upon the skin with ink before beginning the dissection of the flap. It must be remembered that when the flap is formed it contracts very much. At the same time the gap from which it was taken appears larger than is really the fact because of retraction of the margins of the wound. Nevertheless, it is well to make the flap at least one-third larger and much thicker than the space into which it is to be interpolated would seem to require, since the flap shrinks at once and undergoes contraction and absorption from cicatricial changes for many weeks after union has occurred. Any redundancy can be readily re- moved when lapse of time proves it actually to exist. To guard against imperfect nutrition and consequent sloughing of the flap, it is well to make it with its long axis corresponding with the direc- tion of arterial supply, and its base presenting toward the cardiac portion of the arteries. Where there is very free anastomosis, as upon the face, this rule may be disregarded to a considerable extent. The calibre of the supplying vessels must not be interfered with by too much twisting or tension of the pedicle, which must always be wide and thick. Injurious tension on the pedicle can frequently be prevented by cutting a pedicle with curved margins, which will allow increased stretching without occluding the vessels. Skin free from hairs should be selected when possible, unless it is desired to make eyebrows. A gap to be filled by interpolation and parts to be united by approx- imation should have their surfaces prepared by such free incisions as will give abundant areas of contact for union by first intention. It is an error to pare away so little tissue that only a thin raw edge is obtained. It is necessary to have broad surfaces of contact to make successful plastic operations, and these must be obtained even at the sacrifice of consider- able material. The additional material removed will not be so great but that it can be supplied during the subsequent steps of the operation. Operations for harelip and torn perineum are often imperfect because of neglect of this rule. - When all hemorrhage from the flaps and freshened edges has been con- trolled, accurate approximation is to be made by numerous sutures, which should hold the parts merely in contact, allowing them to lie loosely and Without tension. It is important in constructing new noses and other features to be satisfied at first with obtaining a bulky semblance of the organ, and not to endeavor to trim down the structures to an accurate conformation, because it is impossible to estimate the amount and char- actºr of cicatricial shrinkage which will inevitably occur. - Exudation and organization of lymph sufficient to hold the parts to- gether with moderate firmness occurs in from two to three days; then Some or all of the sutures may usually be removed. Metallic sutures °ºuse so little local irritation that they may be allowed to remain as long *there is any danger of disruption of the adhering parts. The silk *ures, which are often useful in securing accurate adjustment at the Very edges of the wounds, are generally removed early. Gut sutures *y be allowed to remain until they fall off from absorption of the por- * lying in the tissues. Absolute antisepsis adds greatly to the success 150 P L A ST IC O R R EP A R AT IV E S U R G E R Y. of plastic operations, and causes healing with the minimum degree of scarring. In transplanting without a pedicle, it is of the utmost importance that the tissues be kept absolutely aseptic and warm. Disks of bone, pieces of nerve, skin shavings, and such tissues, when to be thus used, should be kept warm in sterilized water of about 105° F. If antiseptic solutions are employed, they should be weak and unirritating. The success following well devised and carefully performed plastic operations is very gratifying. It is especially so in cosmetic operations, since the improved appearance, though not equal to the normal condition, is of great solace to the disfigured patient. It is always a long time be- fore the cicatrices become white and soft ; therefore the full result is not apparent until many months have elapsed. The scars always remain visible, however; hence the illustrations of many published cases] are deceptive in the apparent absence of scarring. The disabilities due to fistules, ruptured perineum, and many other conditions, can often be entirely removed by plastic surgery. If gangrene of the flap does not occur before the end of the fourth day it is not likely to take place, and the integrity of the operation is pretty well assured. If, however, during the first three or four days the flap becomes grayish and pulpy, and shows a loosened cuticle, or, on the other hand, if it assumes a dry and withered appearance, it is evident that destruction by sloughing of more or less tissue is supervening. The surgeon should, nevertheless, leave the parts in position, keep them warm, and disturb the dressings as little as possible, because the gangrene may involve only the edges or the superficial layers of the flaps. A small amount of living tissue remaining after the limitation of the sloughing process will often be very serviceable in making the operation entirely, or at least partially, successful. FIG. 54.

I N P L ASTIC S U R G E R Y . 151 Harelip, as will be shown in another part of this treatise, is usually remedied by paring the edges of the cleft and approximating the fresh- ened surfaces with the pin suture. Ectropium, or eversion of the lower eyelid from cicatricial contraction, is greatly improved by making a V-shaped incision downward, with its base embracing the everted section of the lid, and dissecting the tense structures from the adjacent muscles so that the V-shaped area of the skin can be slid upward until the lid assumes its natural position. This re- lieves the downward tension without FIG. 56. materially disturbing the blood-supply of the somewhat poorly nourished cicatricial tissue. The gaping wound left below and laterally can usually be closed by stretching the skin or by interpolating flaps. This principle of relieving tension can be utilized in many regions after deformity from burns. The point of the V must always be in the line of greatest tension. Depressed and irregular cicatrices, such as occur in the neck after chronic suppuration of lymphatic glands, can be rendered more sightly by carrying an elliptical incision around them, freeing the integument laterally, and drawing the under-cut skin over the depression, which has previously been made raw by abrasion. This method gets rid of the depres- sion and leaves a linear cicatrix.

The septum, or at least the columna, can be weiſ made out of a piece cut from the entire thickness of the upper lip. Portions of the nose may be restored by flaps from the cheeks or upper lip. It is well to remember that taking portions of the lip away gives a flattened nose a imºre, marked prominence; hence, two indications are fulfilled by using labial flaps for rhinoplastic procedures. The parts may be kept in place by transfixing the organ and the septum with pins, or tubes or plugs may be placed in the nostrils for a few days.

SURGERY OF SPECIAL STRUCTURES. DISEASES AND INJURIES OF THE SEIN AND ITS APPEND AGES AND OF THE SUBCUTANEOUS TISSUE. THE cutaneous eruptions do not belong to the domain of surgery, and therefore will not be discussed in this treatise. Ulcers, wounds of the Soft parts, and tumors have had sufficient attention given them in the preceding chapters, hence no further reference to them is required in this connection. WART OR VIERRUCA. DEFINITION.—A wart is a circumscribed hypertrophy of the cutaneous papillae. PATHOLOGY..—It is in fact a papilloma, and may have a smooth or rough surface according to the arrangement of epithelium covering the enlarged papillae. The histology of papilloma is discussed in the chapter on tumors. Warts may be quite hard and horny, as in the common form found on the hands, moderately soft, as seen upon the backs of old persons, or very soft and friable, as the moist verrucous vegetations situated upon the anal and genital muco-cutaneous surfaces. The last are not syphilitic, but depend upon an irritation due to muco-purulent discharges of any kind. The discharge may be venereal, but this has nothing to do with its causing the warts. The growths are very vascular and may be the source of hemorrhages. The fetid odor is due to decom- position of the secretions. The other forms are not very vascular and are usually darker than the adjacent skin. Warts on mucous membranes often bleed freely and in the bladder and urethra may cause obstruction to urination. A warty growth occurs on the hands of those engaged in making post-mortem examinations, as a result of irritation from the cadaveric fluids. . The horny wart at times disappears spontaneously, hence the reputa- tion of many household applications. TREATMENT-Excision with scissors or curette or repeated cauteriza- tion with chromic acid, glacial acetic acid, or ethylate of sodium is the best treatment. A mixture of salicylic acid (gr. xxx), extract of canna- 154 SU R G E R Y O F SPECIAL S T R U C T U R ES. bis indica (gr. x), and collodion (3.j) is recommended to be applied daily. After a few days the devitalized tissue should be scraped off. Ligation may be employed if the wart is pedunculated. The soft warts, often improperly called venereal vegetations, may be treated in the same way, though, when large, provision against hemor- rhage must be made by the surgeon being ready to apply pressure or astringents. Powdered tannic acid I have found a good styptic appli- cation. The écraseur or the actual cautery may be used for removing very large masses of these vegetations. CORN OR CLAVUs. DEFINITION.—A corn is a small, circumscribed, cone-shaped callosity, due to hypertrophy of the epidermis, usually situated upon the feet or hands, and having its apex pressing upon the papillary layer of the skin. PATHOLOGY..—A corn is originally a papilloma or wart, but as the epidermis thickens it is pressed into the underlying tissues like a nail driven into a board and the papillae finally atrophy. The cause of corns is pressure, of misfitting shoes or from some instru- ment used in manual labor, which induces chronic inflammatory hyper- lasia. p The pain is due to pressure on the delicate papillary layer of the true skin, between which and the callosity a small bursa is sometimes developed. If active inflammation and suppuration occur beneath the corn, the pain is intense, because the pus cannot escape through the thickened epidermis. When moisture is constantly present, as between the toes, the corn is macerated and is called a soft corn. Pathologically hard and soft corns are the same. A hard corn is occasionally found under the toenail. TREATMENT.—The treatment consists in removing pressure by wearing broad-soled shoes, straight along the inner border, with low heels. The hardened epidermis may be scraped or cut away. This is best done per- haps after softening the epidermis by soaking in hot water, by poultices, or by applications of alkaline solutions, such as sodium carbonate (gr. X. to fºj). In using strong alkalies care should be exercised not to touch surrounding parts. The corn may be surrounded with a ring of wax. As the removal of the horny exterior relieves the pressure on the true skin, pain will be mitigated by these measures. A thick pad or plaster with a central perforation to admit the callosity will palliate pain in the same way. The salicylic acid application given for the treatment of warts is often beneficial in cases of corns. Strong applications of nitrate of silver will often relieve the pain of either hard or soft corns. Inflamed corns require elevation of the foot and moist antiseptic dressings. Gauze moistened with an antiseptic solution and covered with rubber tissue, oiled silk or waxed paper is an antiseptic poultice and is valuable. Soft corns are benefited by dusting tannic acid or oxide of zinc upon them. These modes of treatment are only palliative. Excisions of the horny cone- shaped mass by careful dissection or by cutting out an elliptical portion of tissue down to the superficial fascia is the radical treatment. If abscess occurs under the corn prompt incision will relieve pain and probably effect a permanent cure. It must be remembered that the peripheral circulation in the feet of old and infirm persons is not vigorous; hence, slight operative interference may be followed by gangrene in such patients. B O II, O R F U R U N C L E . 15: 5 BOIL OR FURUNCLE. DEFINITION.—A boil is a circumscribed, painful, and reddish elevation, due to a localized inflammation of the skin and cellular tissue usually terminating in central suppuration and sloughing. PATHOLOGY..—Furuncles occur singly or scattered over the surface in crops, showing a predilection for the back, axillae, perineum, buttocks, legs, and face. They are at times associated with diabetes and other diathetic condi- tions. There seem to be two classes of boils: Those primarily superficial, due to local irritation about a hair follicle or sebaceous gland, as when the hands are exposed to irritating fluids in dissecting; and those which begin deeply on account of a localized depressed state of resistance in the cellu- lar elements of the skin and subcutaneous tissue. Boils occur among those of depraved physical condition and in those of robust and vigorous health. Sea air has a tendency to induce their appearance in many people. The cause of furuncle is a mycotic one. The cocci in many in- stances enter the sebaceous duct or hair follicle from the surface of the skin. In other cases, probably, they are in the blood and become local- ized at a point where the tissues have least resisting power. This explains the location of boils and their occurrence in the healthy. SYMPTOMS.—The sharp stinging pain felt upon accidental pressure may first call attention to a small, red pimple, which gradually enlarges, be- comes hard and purplish, and is surrounded by a red areola. The pain becomes throbbing and constant, about the fifth day a yellowish spot at the apex of the elevation proclaims the occurrence of suppuration and in a day or two longer a cylindrical greenish-yellow core or slough of cellular tissue is discharged by the suppurative process, leaving a deep, punched- out looking cavity. This is gradually filled by granulations, the adjacent exudation of lymph is absorbed so that the tissues around regain their normal softness, and cicatrization is finally accomplished. The course of a moderate size boil, that is, one which with its areola is say 13 inches in diameter, is run in eight or ten days. Pain subsides as soon as the slough or core is discharged. Smaller boils or pimples fre- quently appear about the same locality some days after the disappearance of the primary boil. Lymphatic glandular involvement is common during the height of the inflammation. Occasionally the inflammation terminates by resolution, and as no discharge takes place such furuncles are termed blind boils. Severe boils usually cause some fever. The diagnosis between furuncle and its congener, carbuncle, is made by the single point of suppuration, the circular and conical shape, the smaller size, the tenderness on pressure, which does not exist in carbuncle, and the usual association with other boils. TREATMENT-It is sometimes possible to abort furuncle by early appli- Cations of tincture of iodine, nitrate of silver, blisters, or undiluted carbolic acid, or by puncture with a red-hot needle; but such procedures seem at times to cause the subsequent irruption of a more than usually virulent furuncle, which cannot be kept in check by such measures. Carbolic acid has been injected into the forming boil with alleged advantage. Pain is quieted and suppuration probably hastened by wet antiseptic dressings covered with rubber tissue or oiled silk so as to constitute poul- tices, and by anodyne plasters, of which belladonna plaster is one of the 156 SU R G E R Y O F SPECIAL ST R U C T U R ES. best ; but these are far inferior to early and free incision, which relieves tension and pain, depletes the engorged tissues and allows rapid extrusion of the slough. It is the effort of the dead cellular tissue to escape that, in the majority of instances, causes much of the pain. My usual course is to wait only until the boil becomes quite painful, when I at once make a deep incision without waiting for pus. Scraping the diseased tissue out with the curette while the patient is etherized may hasten cure. This, especially if followed by moist anti- septic dressings and removal of the slough with forceps, speedily relieves pain and shortens the duration of the disease several days. Dry anti- septic dressings should be used after the slough has been removed or dis- charged. The treatment of the condition giving rise to a succession of boils (furunculosis) is difficult, because a determination of the underlying causes is often impossible. Impoverished blood demands iron, quinine, mineral acids, cod-liver oil, malt and alcoholic beverages, and pure air. Arsenic (gr. ºn to Hº), hyposulphite of sodium (3ss to 3.j), sulphide of calcium (gr. j to gr. iv), and solution of potassa (mixv to mixxx) have Some reputation as antagonists to the furunculous diathesis, and one or other may be administered three or four times daily. Eliminative measures, such as the Turkish bath, should be employed; and any gastric, intestinal, or genital derangement corrected. Thorough cleansing of the skin with soap, aided, perhaps, by turpentine, ether, and non-poisonous antiseptics, seems most philosophical. The occasional association of fur- unculous inflammations with syphilis, septicæmia, nephritis, and diabetes must not be forgotten. When healing does not progress after separation of the slough, the superficial ulcer left requires such management as has been previously detailed in the discussion of ulcers. CARBUNCLE. DEFINITION.—Carbuncle is a more or less localized, deeply seated Sup- purative inflammation of the skin and cellular tissue, attended by a hard, very painful, flattened swelling and asthenic symptoms. PATHOLOGY..—This section does not discuss the disease called malignant pustule, or anthrax, which is spoken of in an earlier chapter. Unfortu- nately the term anthrax is applied to both diseases. They may be related. Malignant pustule is certainly due to the anthrax bacillus. Carbuncle is probably due to a pyogenic Organism. There is a great clinical similarity between furuncle and the more severe disease, carbuncle; while there is apparently a pathological or etiological relationship between carbuncle and malignant pustule and erysipelas. SYMPTOMS.–Carbuncle is usually single and is most frequent in elderly people and in those of impaired health; it is often associated with dia- betes and chronic renal disease. A chill may be the premonition of the carbuncle, which appears as a painful red spot, perhaps surmounted by a vesicle. The posterior part of the trunk and neck is its favorite locality. A firm, flattened, dusky red swelling, evidently involving a considerable depth of tissue and exceedingly painful, though the pain is not much increased by pressure, soon shows that a mere furuncle is not to be expected. The brawny inflammation is localized, though it evinces some tendency to spread, which is quite unlike the sharply defined fur- unculous affection. This suggests a possibility that carbuncle may be due C A R B U N C L E . 157 to the streptococcus pyogenes and furuncle to one of the other pus-causing fungi. The feeling of tension and the throbbing pain are very marked, the muscles in the vicinity become stiff from pain, and glandular swelling is quite prominent. After the lapse of ten days or two weeks the skin softens, first perhaps becoming vesicular, and is riddled by gangrenous openings through which sloughing cellular tissue and ichorous pus is dis- charged. Tough fibrous cores or sloughs are extruded and the continuous destruction of skin goes on until there is left a deep excavated ulcer with irregular indurated margins. The diameter of a carbuncle varies from one to six inches and it may extend down to the underlying muscular tissue, but rarely goes beyond. The duration of the disease is a month or six weeks, though this period may be greatly lengthened by indolent cicatrization of the ulceration. The prognosis is exceedingly unfavorable when the carbuncle is large and situated upon the head or neck, especially if the patient is old or infirm. The constitutional symptoms are asthenic, and are of course more grave if the sloughing causes profuse hemorrhage. TREATMENT.-The internal treatment, therefore, comprises supportive and anodyne measures, for even preliminary depletion would be inadvis- able. Quinia (gr. x-xx daily), dried sulphate of iron (gr. iij-vj daily), and milk punch (whiskey, f 3 j-v daily) represent the character of agents to be employed in severe cases. Ice has been recommended as a local application in the early stage to cause the disease to abort. Blisters are sometimes employed with a sim- ilar object, and are also sometimes applied around the carbuncle to pre- vent extension of the inflammation by causing abundant effusion of serum. Circular compression made by plasters with a central hole over the focus of inflammation or by a cupping glass has advocates, who think that the progress of the carbuncle is limited or its severity lessened by this device. When it is evident that arrest cannot be accomplished, moist antiseptic dressings, covered with rubber cloth to prevent evaporation, are the proper applications to hasten suppuration and the discharge of the gangrenous tissue. Thorough cleansing with sublimate solutions (1:1000) of the cavities under the perforated and sieve-like integument is judicious. Cicatrization of the resulting ulcer is accomplished as in ordinary cases of ulceration after gangrene. Stimulating ointments or lotions and skin-grafting may be required. The cicatricial contraction is usually less than would seem probable from the extent of the ulceration. This is due to the fact that the thickened and indurated edges give the ulcer a factitious depth. I have purposely omitted the discussion of the propriety of incising Carbuncles until now, because high authorities differ as to the therapeutic Value of incision. Some surgeons seldom incise them and believe that the operation as a rule neither hastens cure nor lessens suffering. Others think that incision is beneficial because it relieves the tension and conse- quent interstitial strangulation, diminishes pain, and allows early escape of pus and sloughs. If the parts are relaxed and soft no incision is re- quired; but tension is so nearly universal that I am impressed with the Value of free early incision, at least in the majority of cases. The creak- ing as the knife divides the tissues shows the great induration. My opinion does not differ from that expressed under the treatment of boils. Subcutaneous incision is inferior to a direct incision which may or may not be crucial. Capillary hemorrhage may be pretty free, but will relieve engorgement, and is not likely to do harm, even in the asthenic condition 158 SUT R G E R Y O F S P E CIA L ST R U C T U R ES. present, unless a vessel of considerable size is wounded. Pressure with compresses and bandages will control such capillary oozing if it is suffi- cient to require treatment. Applications of very hot water have a styptic influence. Early curetting of the diseased region so as to remove sloughs, pus, and disintegrated tissues seems to me rational. It must be done under anaesthesia, and the cavity made antiseptic. The diseased struc- tures may be destroyed without hemorrhage by the application of caustic potassa, which cauterizes and causes chemical destruction of the skin and subcutaneous tissue. Thorough cauterization with a red-hot iron thrust through the skin and carried under the skin in all directions may, if used at an early period, destroy the pyogenic organism and prevent spread of the phlegmonous inflammation. It seems to me a valuable suggestion. LUPUs. DEFINITION.—Lupus, or lupus vulgaris, is a chronic cellular infiltra- tion of the skin, exhibiting itself as irregular, nodular, reddish-brown patches of granulation tissue, which may or may not proceed to destruc- tive ulceration but which usually leave disfiguring cicatrices. Lupus, as previously stated, is probably a form of cutaneous tuberculosis, due to the tubercle bacillus. PATHOLOGY..—The disease has an important surgical bearing, because there is a liability of its being confounded with syphilitic and epithelio- matous ulceration. The superficial form of lupus, erythematous lupus as it is called, is a very different affection from ulcerating lupus. It is a skin disease located especially in the sebaceous glands and does not interest the surgeon. SYMPTOMS.—Lupus begins as a group of small, hardened, reddish brown points in the skin which increase until they become papules or tubercles. The patch may enlarge or several small patches may coalesce. There is no pain. Cure may occur at this stage by absorption of the nodules, leaving an atrophic kind of scar; or destructive ulceration of the affected skin may take place. Such ulceration is exceedingly chronic and is characterized by accumulation of crusts, slight discharge, slow in- volvement and destruction of underlying cartilaginous structures, and contracting cicatrices which cause marked deformity. Ulcerating lupus usually attacks the face in the neighborhood of the mouth, nose, and ears, but may appear upon other parts of the body, especially the fingers. There may be slight pain in the later stages of the disease. The causation of lupus has been obscure, but is now believed by many to be due to the tubercle bacillus. The general health may be good. It occurs in children chiefly, and is rare in this country, except among the foreign element of our population. - Lupus must be carefully differentiated from syphilitic ulcers and from epithelioma, which shows a predilection to attack similar regions of the face. & Lupous Ulceration. Syphilitic Ulceration. Comparatively superficial. Quite deep, often excavated. Area rather small. Area may be quite large. Ulceration usually limited to one region. Ulcers often disseminated over surface of body. Increases by coalescing of adjacent patches. Ulcers remain separate. Border illy defined, Border sharply defined. LU P U. S. 159 Lupous Ulceration. Discharge slight and not felid. Scabs thin and reddish-brown. Progress slow, takes months to develop. Scars hard, yellowish, and have great tendency to contract. No other lesions. Not improved by medicinal treatment. Lupous Ulceration. Usually upon face, may attack other parts. Induration not very marked and is diffuse. No pain. Ulceration begins at several points of the patch. Destruction of tissue usually not very reat. No hard and everted border ever present. Ulcer usually rather superficial, with base of small, red granulations. Slow in its progress. Occurs especially in children. Syphilitic Ulceration. Discharge abundant and foul. Scabs thick, often greenish. Progress more rapid, a large ulcer will de- velop in a few weeks. Scars soft, whitish, have little contractile tendency. Lesions of bones, glands, etc. Cured by mercury and potassium iodide in full doses. Epitheliomatous Ulceration. Situated usually at muco-cutaneous junc- tions. Induration well marked and circum- scribed. Pain may be quite severe. Ulceration begins at one point and spreads. Destruction and loss of substance great. Indurated and everted border a charac- teristic. Ulcer deep, with uneven base and foul discharge. More rapid in its progress. Occurs especially in adults and aged. It will be seen that the clinical history of the ulcerative stages of these affections—lupus, syphilis, and epithelioma—are very different. I am convinced that many cases described as lupus have really been epithe- lioma, for the great destruction of tissue and abundant discharge and pain attributed to lupus are antagonistic to its ordinary clinical features. Rodent ulcer, which is a form of epithelioma, lupus and syphilis, have been confounded by many writers, who have thereby confused the pro- fession. TREATMENT.—This intractable affection requires active and prolonged treatment. Good, nutritious food, general hygienic measures, and consti- tutional and local remedies are demanded. Cod-liver oil (fºij to fºss), iodide of potassium (gr. v-x), and syrup of iodide of iron (fºss to faj) are probably the most valuable internal remedies, and should be tested before severe local applications are adopted. Arsenic is a constitutional remedy worthy of trial. Caustics are necessary as topical remedies, unless absorption of the infiltration occurs in the early stages of the disease. Absorption may possibly be assisted at this time by painting with tincture of iodine, undiluted or mixed with glycerin, or by applying tar or some murcurial ointment, or using iodoform powder. Later it becomes necessary to use caustics to destroy the diseased tissue. Nitrate of silver is highly recommended by Hebra, but it is not as powerful as other agents, which, however, in some instances destroy the healthy as well as the unhealthy skin. Potassa and lime are painful applications, and have a very destructive tendency; hence, the surrounding parts must be protected by pieces of plaster or cloth, and some weak acid should be at hand to neutralize the alkali if *Cessary. Arsenious acid (gr. xx-xxx to 3 of ointment) is painful, but acts. only on affected structures. Pyrogallic acid ointment (3 to āj) is painless, and acts very slightly on the normal tissue. Chromic acid, to which a few drops of water have been added, applied with a brush, is ºny favorite for such purposes. Solution of ethylate of sodium may be 160 S U R (; E R Y O F S P E CIA I, S T R U C T U R. E. S. used and is efficacious as a destroyer of abnormal structures. Scraping away the diseased skin with a sharp-edged scoop, or curette, and applying caustics subsequently, such as zinc chloride or one of those mentioned above, is a proper and often an efficient method of treatment. The thermo-cautery, or galvanic cautery, is an available method of obtaining a similar object. Excision of the ulcer may sometimes be justifiable when the gap can be closed by a plastic procedure. Multiple incisions are said to be beneficial by arousing traumatic inflammation. ARABIAN ELEPHANTIASIS. DEFINITION.—Arabian elephantiasis, or Barbadoes leg, is a local dis- ease, characterized by chronic hypertrophy of the skin and underlying cellular tissue, giving rise to discoloration, thickening, induration, warty growths and deformity. * It is essentially different from Grecian elephantiasis, or lepra, the Biblical leprosy, which is probably due to a vegetable parasite, the bacil- lus of leprosy. Leprosy does not belong to the domain of surgery. FIG. 62, Arabian elephantiasis. SYMPTOMS.–The first step in the disease is a local inflammation of an erysipelatous kind, accompanied by involvement of the lymphatic vessels and glands. This attack subsides, leaving the part, usually a leg or the genitals, somewhat enlarged and Oedematous. Recurrence of such inflam- matory conditions takes place at intervals, leaving in each instance more thickening and deformity. In the course of a year or two the hypertrophied skin and subcutaneous tissue cause the part to assume enormous propor- tions. The thickened, hardened skin hangs in irregular folds, and the surface often becomes eczematous. From the accompanying fissures and ulcers bloody serum exudes and causes scabs to form. The surface may be smooth and eczematous, or very rough, from the development of papil- lary enlargements or warts. The enlarged region is usually darker than natural and greatly mis-shapen. The decomposing secretions, if abund- ant, give rise to fetor. The great weight is a source of inconvenience, and pain or itching may at times add to the patient's discomfort. During Blj H. N S. 1618 the active inflammatory periods fever is present, and the local symptoms are more SéVere. Arabian elephantiasis is not common in the United States, but is fre- quently seen in the West Indies, South America, and other tropical coun- tries. A condition resembling, if not identical with it, is not infrequently seen associated with chronic leg ulcer. The cause is obscure, but is prob- ably connected with the lymphatic system. The disease is attributed by some investigators to occlusion of the lymphatic vessels by an animal parasite, the filaria. It is found among the poor, especially in adults, and is neither hereditary nor contagious. It is always chronic in its progress, and does not tend to a fatal issue. One of the legs, the scrotum, penis, or vulva is the usual situation of the disease. Pathologically it consists of an hypertrophy of the skin and areolar tissue, with enlarged blood vessels and dilated lymphatics. In very pro- tracted cases muscular atrophy and degeneration, and thickening of the bones take place. TREATMENT.-It should be treated in the acute inflammatory stages by rest in the horizontal posture, and by cold water and anodyne applica- tions. When these symptoms have abated inunction with mercurial oint- ment, painting with tincture of iodine, and the application of the elastic bandage are the best methods of inducing absorption and diminution of bulk. Continuous elevation of the limb should always form an impor- tant factor of the treatment. The rapid decrease in size under elevation and frequent readjustment of the elastic bandage is often a matter of astonishment, but the hypertrophy is liable to return when the patient regains the erect position. The eczematous complication is often bene- fited by a paste of salicylic acid (3ij), carbolic acid (3ij), zinc oxide (3ss), mucilage (3xx), and glycerin (3xx). Ligation of the main arterial trunk has been followed by amelioration, and Dr. T. G. Morton, of Philadelphia, has reported very favorable results in a case where he excised an inch and a quarter of the sciatic nerve five years after ligation of the femoral artery had been performed with partial success. Amputation may, at times, be justifiable. BURNs. DEFINITION.—Burns are injuries produced by the application to the surface of heat sufficient to cause inflammation or destroy the vitality of the tissues. Scalds are burns due to contact with hot fluids. PATHOLOGY..—Sunburn is a dermatitis or inflammation of the skin resembling that caused by heat, but due to exposure to the sun's rays. Such inflammation is prevented by protecting the skin with dark veils or clothing, and, when caused, is to be treated as an ordinary burn by cool- ing and anodyne applications. Injuries due to the chemical action of strong acids and alkalies are improperly called burns, though the effects are similar to those caused by heat. . Injuries from chemicals should be treated locally at first by weak alka- line or acid solutions to neutralize respectively the acid or alkali doing the mischief. The subsequent treatment is identical with that of burns. Lightning and contact with electric light wires sometimes cause burns, in addition to the nervous phenomena due to the electric current. Thé burns are to be treated as other burns. The local effects of contact with heat necessarily depend upon the tem- ; 11 162 S U R G E R Y O F S P E CIA L S T R U C T U R E S. perature and the time of exposure. There are practically only three classes of burns: 1. Erythematous burns, or those so superficial in their influence that nothing further than hyperaemia and slight serous effusion into the skin occur. 2. Vesicating burns, which do a greater degree of damage, and are followed by vesicles resulting from an effusion of serum between the derma and epidermis. 3. Necrotic burns, which are followed by eschars, because the upper portion of the derma, or, perhaps, the whole thickness of the skin or the muscles, fasciae, and bones, are devitalized. SYMPTOMS.–In erythematous burns the skin is red, painful, and swollen; but these inflammatory symptoms subside in a few hours or days, and no cicatrix is left, even when desquamation takes place. Vesicating burns promptly show vesicles or blebs filled with clear or blood-stained serum, and are the seat of active inflammation causing severe pain. The serum escapes by rupture of the vesicle, or is absorbed, and a new epidermis is formed in the course of a week. If the old cuticle is early cast off or removed by friction, so that the cutis is exposed to irri- tation and to pus infection from pyogenic germs, in the air or on the clothing, great pain and superficial suppuration result. No cicatrix follows vesicating burns, though a discolored stain, similar to that often seen after blistering with cantharides, may remain for a con- siderable period. Necrotic burns destroy the vitality of the tissues; therefore the eschars, when separated, leave ulcerated surfaces to heal by granulation. The pain of such burns is intense, if shock does not prevent its being felt. The dirty brown color of such burns is characteristic, but it is impossible to tell how deep the destruction has been until the sloughs separate. If the parts are kept aseptic there will be no suppuration under the eschars, which will drop off when the parts beneath are healed. Cicatricial con- traction and deformity are usually great. The cicatrices may assume a very rough and irregular appearance from abnormal development of fibrous tissue. Keloid and malignant degenerations at times attack such scars. The constitutional effects of burns vary with the amount of surface in- volved and the degree of burning. An erythematous burn of a large surface will cause more dangerous symptoms than a deeper burn of limited area. When burns are severe enough to cause constitutional manifestations, these symptoms are exhibited in three stages: 1, that of shock; 2, that of inflammatory fever; 3, that of exhaustion. The stage of shock is accompanied by feeble, frequent pulse, great de- pression of the nervous system, lowered temperature, chills, nausea, rest- lessness, and perhaps delirium. Pain is not very prominent if shock is great. Greater shock attends burns of the trunk than of the limbs. Congestion of the brain, of the thoracic and abdominal organs occurs, and the patient often dies in twelve or twenty-four hours without showing any reaction from the collapsed state. The degree of shock shown by children and the aged is greater than in the middle period of life. The stage of inflammatory fever, which lasts from the second to about the fourteenth day, is characterized by increased bodily temperature, dis; ordered secretions, great thirst, and often by inflammation of the internal organs, such as cerebral meningitis, bronchitis, pleuro-pneumonia, and enteritis. It is due largely, if not entirely, to infection by putrefactive and pyogenic germs of the burned surfaces. Ulceration of the duodenum, sometimes proceeding to perforation, is a remarkable lesion occurring at times during this stage. It is to be suspected if hypogastric pain, vomit: ing of blood, abdominal tenderness, and bloody stools are observed. Its BU R. N. S. 163 occurrence has been attributed to the unusual vicarious action thrown upon the duodenal glands, and also to a possible embolic plugging of the vessels of the intestine. Neither of these theories has been proved. Duodenal ulcer, if it occurs, is developed, as a rule, about the seventh or tenth day of the inflammatory stage. In this stage albuminuria vary- ing with the temperature, and a small vascular eruption thickly scattered over the trunk, have been noticed. Erysipelas may occur. The stage of exhaustion is due to the depression caused by the inflam- matory irritation, and by the profuse suppuration often accompanying the detachment of the eschars and the cicatrization of the resulting ulcers. The suppuration is due to pyogenic infection, which is difficult to pre- vent when large areas are injured. Infection usually occurs before the surgeon reaches the burned individual. There is great debility but no pain unless the ulcers are subjected to pressure or rudely handled in reapplying dressings. Amyloid visceral changes may possibly result from prolonged suppuration. Few cases of severe burn, and superficial burns must be considered severe if one-third of the surface is injured, survive until the suppurative stage begins. The majority die of shock within the first thirty-six hours. Many others die during the inflammatory stage from lesions of the in- ternal organs, tetanus, etc. Inflammatory oedema of the glottis from inhalation of steam may be a cause of death ; but flame itself is not in- haled, as is supposed by the laity. In most instances where incinerated bodies are found in burned buildings asphyxia has occurred from the gaseous products of combustion before the tissues have been subjected to the action of fire. Spontaneous combustion of the human body is im- possible. TREATMENT.-The constitutional treatment of burns should be di- rected to the relief of shock and pain, the prevention of secondary visceral inflammations, and the support of the general powers of the system ; while topical remedies should be employed to relieve pain, moderate local inflammation, prevent infection with pus and other germs, hasten cicatrization, and prevent contractile deformity. Reaction from shock should be sought for by the application of heat and the administration of stimulants and concentrated food in small quantities. The hot bath may be available to raise temperature and re- lieve pain. In fact, all the measures spoken of in the chapter where Shock after Wounds is discussed are to be employed. Pain is to be relieved in severe cases by an immediate hypodermic injection of a quarter or half grain of morphia, or by the inhalation of an anaesthetic. In the later stages of burns laxatives, diuretics, revulsives, and other anti- phlogistic measures may be demanded to prevent internal inflammation and to substitute the derivative action of the skin. The stage of exhaus- tion prečminently requires tonics; and on this account actively depressing remedies are to be avoided in the inflammatory stage. The local treatment varies with the degree of burn. Erythematous burns, if limited in extent, are relieved of pain by solution of sodium bicarbonate, cold water, lead water and laudanum, and in fact by almost any dressing that excludes air and constringes the dilated capillaries. Menthol or Japanese peppermint might, I think, from its great refrigerant action, be exceedingly soothing. The application of cold to large erythematous burns is ill-advised because of the tendency to depress the surface temperature and congest the internal organs. A household remedy for small burns of this degree is to hold the part near a hot fire 164 S U R G E R Y O F SPECIAL ST R U CTU. RES, and thus apply dry heat. Zinc ointment spread on cloth, and wheat flour dusted over the burned surface are recommended highly. s The proper treatment for vesicating burns is to puncture the blebs care- fully and allow the serum to escape, so as to prevent the epidermis from being rudely rubbed off. This epidermis makes the best possible protec- tion from irritation and septic infection. Antiseptic gauze, or cotton, or some form of dry sterilized dressing should then be applied. Salicylic acid cotton does well. Sublimate cotton would be apt to poison the patient if used for extensive burns. The dressing should not be changed oftener than once in two or three days, because detachment of loosened cuticle and exposure to air increase pain and the liability to germ infec- tion, Antiseptic powders form with the exuded fluids a coating which serves as a good protection from atmospheric influences, and should not be removed until detached spontaneously. Iodoform powder is liable to give rise to toxic symptoms when used in large quantity. Boric and salicylic acids are harmless, or practically so. Much harm is often done by tearing off the epidermis when removing underclothing. It is better, perhaps, in such cases, to leave the soiled shirt or drawers upon the body and saturate it with carbolized castor-oil (1:15) applied upon the outside. Three days later, if the patient live so long, less harm will be occasioned by cutting and removing the garments. In this method suppuration is to be expected since infection from the skin and clothing is almost certain. Necrotic burns require the same line of treatment as vesicating burns, with which indeed they are usually associated. After separation of the sloughs the ulcers are to be treated as previously described under Ulcera- tion. Metallic astringents are often exceedingly valuable to keep down redundant granulations and hasten repair of the breach of continuity. Skin-grafting, in its numerous forms, is often required, and lessens con- traction of the cicatrix. Deep burns of extremities may be so destructive to tissue or so threaten life by reason of spreading gangrene, hemorrhage, or violent inflammation that amputation gives the best prospect of re- COVer W. wºn possible burned surfaces should at once be rendered aseptic by thorough cleansing and disinfection with antiseptic solutions. To do this etherization and scrubbing the burned surface with soap and a brush may be justifiable if the patient's condition does not contra-indicate. Deaths occurring after the period of reaction are largely due to sepsis. The greatest ingenuity has to be called into play in the endeavor to prevent cicatricial contraction, which is especially marked when a deep burn has injured the surface of a joint. The irresistible power of the scar contractility everts the margins of mucous orifices, as in ectropium, narrows the outlets of normal canals, flexes or extends joints and renders them immovable, drags features out of position, causing horrid deformity, and binds neighboring members together into one mass. During cicatri- zation this contraction should be prevented as much as possible by keep- ing joints extended by splints or by weights applied with adhesive plaster or by elastic bands. Adjacent surfaces should be kept separated by similar measures or by interposed dressings or metallic plates. It must be remembered that two apposed granulating surfaces will readily become connected by union by second intention. In this way several fingers may be united throughout their entire length, if not enveloped in separate dressings. Much can be accomplished by careful and judicious treatment to prevent marked cicatricial deformity; but some disfigurement will often occur despite the best-directed efforts. F R O ST BITE A N D C H I L BLA IN . 165 Recent cicatrices may be stretched to a certain extent, but old ones usually require operative treatment. Correction of deformity may at times be accomplished by multiple in- cision of the scar tissue, or by subcutaneous incisions and unfolding of inodular ridges. Plastic operations are often requisite and gain the desired end by transferring the tension to some neighboring region where the cutaneous structures are sufficiently distensible to allow traction with- out causing distortion. The various means of transferring tissue by sliding, twisting, and transplanting with and without pedicles will be found under Plastic Surgery. FROSTBITE AND CHILBLAIN. DEFINITION.—Frostbite is the injury produced by the application to the surface of cold sufficient to cause inflammation or to destroy the vitality of the tissues. Chilblain, or pernio, consists in a local paralysis and dilatation of the capillaries of the skin caused by previous frostbite, giving rise to a bluish- red swelling accompanied by great itching and tenderness, and which may terminate in vesication and ulceration. SYMPTOMs.--When a man is exposed to extreme cold the circulation and respiration become feeble, the limbs stiff and numb, the senses are overcome by drowsiness, and he sinks into a comatose state. If he is not rescued from this condition of apparent death, the fatal issue occurs from congestion of the brain and other organs induced by the contraction of the vessels of the surface. The proper method of restoration is the very gradual application of warmth by means of friction with snow or cold water, followed by removal to a very slightly warmed apartment, and the careful use of stimulants internally and warm embrocations ex- ternally. Friction with clothes should also be made in the direction of the venous current. Artificial respiration and other measures should be persisted in for many hours. It is, however, the local and not the general effects of cold that we are now studying. Frostbites resemble burns, except that their course is slow, and like burns are of three degrees of severity: 1, erythematous; 2, vesicular; 3, necrotic. Erythematous frostbite follows exposure to a moderate degree of cold and is due to the capillary congestion and slight inflammatory serous effusion that succeed the primary contraction of the vessels. The skin during the application of the low temperature becomes white from defi- cient circulation, wrinkled and numb; but as soon as return to warmth occurs a bluish-rédness, swelling, and tingling pain or itching arise. The equilibrium of circulation is restored gradually and no further patholog- ical changes occur. * When the cold is greater or more prolonged the parts become white, entirely insensible and shrunken, and reaction is accompanied by inflam- mation, leading to vesication. The vesicles in vesicating frostbite are filled usually with blood-stained serum, and there is danger of gangrene occurring from the violence of the inflammatory process. Extreme cold devitalizes the tissues at once and they have a mottled appearance from coagulation of blood in the superficial vessels. It is said that the part may be brittle and easily broken, like glass. The necrosed structures are finally separated in the same manner as sloughs 166 S U R G E R Y O F S P E CIA L S T R U C T U R. E. S. produced by heat or chemical agents. In these cases of necrotic frost- bite, as well as in vesicating frostbite leading to gangrene because of active inflammation, it is impossible to tell how much of the tissues is capable of having physiological function restored. Amputation, there- fore, must not be attempted in the primary condition of the injury. The extremities and the peripheral points, such as the ears, nose, and chin, are most frequently frozen, because normal circulation is less active in these localities. For a similar reason persons with weak hearts, and those enfeebled by disease, dissipation, or old age are most liable to suffer from exposure to low temperatures. Parts of the body subjected to constriction from tight clothing, as gloves, or shoes, or kept in contact with metal are especially apt to be frozen. Cold combined with moisture or wind is more dangerous than cold and dry weather without wind. Chilblains are local dilatations of the cutaneous capillaries, due to slight frostbites, usually to freezing that has been repeated. The con- gestion which occurs in these paralytic vessels is accompanied by Oedema, bluish-red swelling, severe itching and burning, and occasionally by the formation of vesicles and intractable ulcers. They are most frequent in women and young persons, and those of feeble cutaneous circulation, and give more trouble when the weather changes from cold to warm than when it is continuously cold. When the limbs become warm after going to bed, or when the patient has been indulging in stimulating food or beverages, the itching becomes almost intolerable. TREATMENT.—The treatment of all degrees of frostbite should begin by preventing sudden return to normal temperature, because sudden access of blood to the injured capillaries will cause pain and a high degree of inflammation. Hence the parts should never be subjected to heat or put in warm water. The circulation and sensibility are to be restored gradually by friction with articles only a little warmer than the frozen parts. Snow, ice water, and wet cloths are usually employed for this purpose. Afterward slightly stimulating applications, such as alcohol, may be used to complete the reaction. Elevation of the limb and friction toward the trunk may be valuable accessories, because the venous return is thus assisted and congestion in the semi-paralyzed capillaries rendered less intense. The erythematous, vesicular, and necrotic inflammations that occur after reaction has been established are to be treated very much as burns of similar degrees. Anodyne and cooling lotions or ointments, evacua- tion of the serum in the vesicles, protection of the skin from atmospheric contact, so as to avoid infection, and moist antiseptic dressings, perhaps, to separate the sloughs, are all indicated in the various degrees of injury. The resulting ulcers are managed as such, without regard to their causa- tion. Amputation is frequently required after severe frostbite, but should not be done until the line of demarcation has been definitely formed. Parts that are insensitive when a needle is thrust into them at the time of freezing, will often have the circulation restored, much to the surprise of the surgeon. The treatment of chilblains is very unsatisfactory. Tincture of iodine : carbolic acid (1:10); carbolized ointment of petroleum; nitrate of silver (1:40); menthol; tincture of cantharides; tincture of aconite root; mus- tard foot-baths; nitric acid (1:30); ammonia; turpentine or camphor liniment; chloroform ; metallic astringents and chloral, as lotions or un- guents, and similar applications, are to be tried. Tincture of iodine I N G R O WIN G TO E - N A I L. 167 (mxx), ether (fāj), collodion (fāj), may be applied with a brush. Perhaps hypodermic injections of fluid extract of ergot (mx) or of ergo- tine (gr. iij) near the seat of pain would be beneficial. All pressure from shoes or gloves aggravates the pain, and should, therefore, be avoided. The ulcers that occur demand treatment calculated to cause healing and to alleviate the itching pain, but care must be observed not to employ remedies that will induce serious inflammation. ONYCHIA OR ONYCHITIS. DEFINITION.—Onychia, or onychitis, is an inflammation and ulcera- tion of the matrix of a nail of the fingers or toes, by which the nail is discolored and usually loosened, and finally cast off. Onychia must be distinguished from paronchia, or felon, which is an entirely different affection. SYMPTOMS.–The condition may or may not arise from injury, and is most frequently observed in children as a simple inflammation and suppu- ration about the root of the nail. The new nail that supplies the place of the diseased one is commonly irregularly developed. At times onychitis assumes a much more serious and intractable form. The ulceration ex- hibits no tendency to heal, the foul discharge and fungous granulations show the finger or toe to be in an unhealthy in- flammatory condition, the end of the member be- FIG. 63. comes bulbous from morbid deposits, and caries or necrosis of the phalanx occurs. This form of Onychia, which is chronic in its course, has been called malignant, and frequently is syphilitic in its Origin. TREATMENT.—The treatment in simple cases con- sists of antiseptic lotions and dressings, and anodyne solutions or ointments. The cases depending upon constitutional states require internal remedies, such as iodide of potassium, mercury, and tonics. Lo- cally, cauterization with solid nitrate of silver or nitrate of lead, or the application of iodoform, of nitrate of mercury ointment, or arsenious acid oint- ment (gr. j. to 3.j) is proper. Scraping away the - fungous granulations and irregularly developed Onychitis. nail tissue often assists in effecting cure. Entire ablation of the nail, and even amputation of the finger may become necessary. INGROWING TOE-NAIL. DEFINITION.—Ingrowing toe-nail is a vicious position of the lateral border of the nail in relation to soft parts of the toe, by which the former is buried in, or overlapped by, the latter. w SYMPTOMs.-The malposition of the nail may be due to abnormal cur- Vature of the same, to tight shoes pressing the soft tissues over its border, or to a collection of hardened cuticle under the nail, causing it to assume an unnatural relation to the adjacent structures. The affection is usually *en at the outer edge of the great toe, and becomes in time very painful, because the constant pressure gives rise to inflammation and ulceration 168 SU R G E R Y O F SPECIAL ST R U C T U R E S. with foul discharge. The corner of the nail may even perforate the substance of the toe. TREATMENT-Palliative treatment consists in allowing the nail to grow forward, and, after scraping away the thickened cuticle beneath, to keep the square corner elevated by a small piece of cotton carefully pushed under it. By a similar piece of cotton or lint the border of the toe should be kept pressed away from the dorsal aspect of the mail margin. The shoes worn must be wide in the sole, be long, and have toes high enough to make no pressure on the top of the nail. The ulceration, if it exists, should be treated with nitrate of silver or nitrate of lead before the cotton is inserted. Salicylic acid (3.jss), extract of cannabis indica (gr. x), collodion (3.j) make a good FIG. 64. application. In inveterate cases the soft parts may be pared away obliquely by an incision beginning as far back as the root of the nail. This fully exposes the ulcer, and by bevelling off the side of the toe prevents the nail irritating the tissues; hence cicatrization and cure usually follow. At times, however, it is better to remove the offending portion of nail. This is done by carrying an incision through the length Operation for ingrowing toe- of the nail, about a quarter of an inch from mail. Tape around root of toe to the edge, beginning far enough up the toe prevent bleeding, and incarcerate to extend beyond the root of nail. A cocaine solution injected hypo- transverse cut is then made from the upper dermically. end of this incision, and a second longi- tudinal one carried through the inflamed skin in such a manner as to liberate the buried border of the nail. The lateral portion of the nail is then pulled away. The unhealthy and swollen soft parts near the mail are generally also trimmed off. The raw surface left by the avulsion is soon healed by granulation under the ordinary dressings for exposed and non-approximated wounds. This is a better operation than removing the entire mail; for, even if both margins have to be cut out, the centre of the toe still retains its covering of nail tissue. In many cases the surgeon can make his second longitudinal incision run under the skin obliquely and thus free the incurvated margin of nail without leaving so large a surface for granulation. This is a sort of a subcutaneous excision of the nail border. The operation is practically bloodless if a piece of tape is tightly tied around the root of the toe before the incisions are made. Cocaine solu- tion may be injected into the tissues so as to produce local anaesthesia. Its incarceration by the tape ligature increases the degree of anaesthesia. § C H A P T E R XIV. DISEASES AND INJURIES OF MUSCLES, TENDONS AND BURSAE. WOUNDS AND RUPTURES OF MIUSCLES AND TENDONS. INCISED and lacerated wounds of muscles and tendons, if they involve the entire thickness of the structure, are followed by retraction of the cut ends and loss of motion. The treatment consists in relaxing the muscular belly by flexion or extension of the joints, and applying sutures to hold the divided muscular or tendinous structures together. In suturing tendons it is well to pull down the upper end strongly in order to stretch and paralyze the muscles and then to overlap the ends and stitch them together in that position by longitudinal sutures. If the tendon is wide the suture illustrated in Fig. 50 is a good one. After suturing the limb should be kept for several weeks in the position which relaxes the muscles. This can be done by bandages or the plaster-of- Paris dressing. If the torn belly of the muscle protrudes through a small cutaneous wound it must be pushed back, even if the opening in the skin requires to be enlarged to accomplish this object. Excision of the muscular protrusion is usually improper. If the upper portion of the tendon is so retracted in its sheath that it cannot be pulled down by narrow-blade forceps, an incision upward must be made so that it can be found. A tendon should be attached to a neighboring tendon or muscle when it is impossible to find the two ends of the severed cord. This will prevent entire paralysis of the finger or limb to which the tendon is in- serted. Tenosuture and myosuture are often neglected in wounds accom- panied by division of the tendons and muscles. In such improperly treated cases the loss of motion may be so detrimental that it is judicious to cut through the cicatrized parts, even after several years have elapsed, and pare the ends of the separated tendon or muscles and suture them properly. As a rule, tendons divided subcutaneously, as in tenotomy, re- unite quickly and satisfactorily as to function; but when their surround- ings have been freely divided, as in open wounds, good union does not follow unless sutures have been applied to the cut tendons. This is due to the great retraction of the muscular end which occurs in such wounds. Subcutaneous rupture of a few muscular fibres is not uncommon in Severe strains thrown suddenly upon the muscles, and usually is accom- panied by sudden, sharp, localized pain and, perhaps, ecchymosis. Rest, the elastic bandage, and massage, supplemented, perhaps, by friction with Some sorbefacient liniment is the treatment requisite. The cure is usually Somewhat slow. Complete rupture of the belly of a muscle or of its tendon, either from the bony insertion or at the musculo-tendinous junction, is rather unusual though not rare. Violence, or a sudden powerful muscular contraction, * in tetanus or in the effort to recover equilibrium when about to fall, is the cause of such lesions. When muscles have undergone fatty or other degenerative changes, rupture is possible from very slight strain; but 170 MUSCLES, TEND ONS AND BU RSAE. these tears are unattended by pain, as a rule, and do not concern us surgically. The tendon of the long head of the biceps, that of the calf muscles, and that of the four-headed extensor of the leg are the tendons most frequently torn. The symptoms of rupture of a muscle or tendon are the occurrence during action of sharp pain, accompanied possibly by an audible snap and associated with almost complete loss of motion, a groove or depres- sion in the surface and, in muscular rupture, ecchymosis. The degree of separation of the ends depends upon the amount of laceration of the sur- rounding tissues and may be as much as an inch. If the tendon is wide Some power of motion may remain because the margin is intact; as in a case seen by me a few years ago, where there was slight extension possible after rupture of the tendon inserted into the patella. Some fibres from the external vastus muscle had evidently escaped rupture. Rupture of muscles and tendons should be treated by laying open the overlying tissues and suturing the torn structures with chromicized cat- gut. The limb should then be placed in the posture which tends to keep the extremities of the torn organ near together, and should be so retained by bandages, splints, plaster-of-Paris dressings or by an apparatus of straps adapted to this requirement. Local weakness remains a long time after union of ruptured muscles and tendons; and the repair that occurs is usually of analogous tissue, which, in the case of tendons, however, finally assumes the characteristics of the original tissue. DISLOCATION OF MUSCLES AND TENDONs. Dislocation of a tendon occasionally occurs when a sudden strain or twist is brought to bear upon it at a point when its direction is changed by passing around a bony prominence. The long head of the biceps of the arm, the long and short peroneal and the posterior tibial tendons are more frequently displaced than any others. Dislocation of the patella is usually practically a dislocated tendon containing a sesamoid bone. Reduction is easily accomplished by relaxation of the muscle and pres- sure upon the displaced tendon, but as the sheath is torn in such luxa- tions, it is difficult to keep the tendon in place after reduction." Pressure with pads and the elastic bandage will often be effectual, but sudden strain is apt to reproduce the luxation and pain. Tenotomy may be resorted to in cases of repeated luxation, as has been done by Mr. Bryant. It is possible that some cases might be benefited by open incision, followed by suturing neighboring structures, so as to prevent subsequent displacement. It is probable that muscles themselves sometimes become displaced from the grooves in which they lie. Such cases would probably be bene- fited by manipulation, followed by bandaging. INFLAMMATION OF TENDONs. SYMPTOMS.—Tenosynovitis, or inflammation of the tendons and their fibrous and synovial coverings, may be acute or chronic. Thecitis, the 1 Comparatively little has been written on these injuries, but the reader may find inter- esting facts in New York Med. Journal, May, 1878, and British Med. Journal, July 13, 1878. IN FL. A M M ATION OF T E N ID O N S. 171 term often used, properly refers to inflammation of the theca or sheath alone, but as both structures are involved in the majority of instances, the word tenosynovitis is a preferable designation of the condition. Acute tenosynovitis is produced by punctured and other wounds, or may arise without any traumatism, and is usually found affecting the flexor tendons of the fingers or toes. The pain and other inflammatory symptoms, both local and constitutional are very severe, and may ter- minate in diffuse suppuration, sloughing, necrosis of the phalanges, and septicæmia. The rapid spread of the inflammation to the hand and arm by burrowing of pus along the tendinous sheaths and by gangrenous cel- lulitis, suggests in many of these cases a resemblance to erysipelas. The severe forms of paronychia, often called whitlow or felon, are usually instances of inflammation of tendons, beginning at the end of the finger. Sometimes the term whitlow is used to signify a mere suppurative inflam- mation of the cellular tissue of the pulp of the finger-tip, a simple abscess in fact; but the destructive paronychia, which is followed by gangrene and necrosis, involves the tendinous structures and periosteum. TREATMENT.-Acute inflammation of tendons demands purgatives, sedatives, and morphia internally, and hot applications and elevation locally, which must, however, be followed very early by free incision to prevent burrowing of pus along the sheaths. A free, longitudinal in- cision should be practised in the middle line of the tendon, going through the structures down to the bone. This should be done as soon as it is seen that resolution of the inflammation will not occur, and without wait- ing for the formation of pus. The limb should be kept elevated after- Ward and enclosed in a moist antiseptic dressing. In whitlow supposed to involve only the structures about the tendon, it has been recommended to incise on both sides of the middle line rather than in the centre of the finger, in order to avoid opening the sheath and thereby allow the sup- purative and sloughing action to involve the tendon. My own opinion is that it is not probable that the incision into the sheath adds materially to the risk of the involvement of the tendinous structures, if the incision is sufficiently free to allow all discharges external exit. Necrosis, subsequent to acute tenosynovitis, may necessitate resection of a joint or amputation of a portion of the finger or limb. - Stiffness or deformity of joints is a frequent sequel of well-treated cases of acute tenosynovitis. Constitutional diseases, such as rheumatism, gout, and syphilis, are liable to cause inflammation of the fibrous tissue of tendons and aponeuro- ses, but this is not of the phlegmonous kind, and demands therapeutic management, depending on the cause. Alkalies, salicylic acid, colchicum, iodide of potassium, and mercury are to be administered as indicated. There is a peculiar form of chronic inflammation of the sheath of ten- dons accompanied by a characteristic creaking or crackling felt, and some- times heard, on motion that must be mentioned. This crepitating thecitis usually occurs in the forearm, and seems to be due to roughening of the sheaths by lymph, which causes scraping when the tendons slip in the *Vesting coverings. The inflammation apparently results from long- 99ntinued and violent muscular action, or from gout or rheumatism, and * associated with a moderate amount of pain and occasionally with tender- º and swelling. The term “thecitis” is properly applied to this con- OD. . The crepitation felt when the wrist is firmly grasped by the other hand is characteristic. Its Superficial character and occurrence during volun- 172 MMSCLES, TEN DO N S A N D B U R SAE. tary motion make it very different from the crepitus of fracture. It should be treated by rest, the elastic bandage, blisters, and friction with stimulating liniments. DEFORMITIES FROM MUSCULAR PARALYSIs, CoNTRACTION, AND RIGIDITY.-MYOTOMY AND TENOTOMY. PATHOLOGY..—Any disturbance of the normal equilibrium of the mus- cular forces gives rise to deformity, hence it is evident that such deformity may be due to increased action of one set of muscles or to impaired power of the opposing group. There are four methods by which muscular dis- tortions occur: 1. Inflammation of muscular tissue (myositis), which is often due to gout, rheumatism, and syphilis, may lead to rigidity and con- traction of muscles. 2. Long-continued abnormal position or disuse of muscles, such as result from an unreduced dislocation of a bone, and from inflammation or anchylosis of a joint, may be, and usually is, followed by Spastic contraction. 3. Lesions in the nerve centres may give rise to par- tial or complete paralysis of a group of muscles, and thus allow the antago- mistic muscles to exert unrestrained force; or, on the other hand, the central nervous disease may cause such a tonic contraction of certain muscles that their opponents are unable to resist the displacing tendency. In either event deformity ensues. 4. Irritation of the peripheral nerves may, by a reflex influence, cause contraction or paresis of neighboring or distant muscles. Such instances are seen in connection with diseased teeth and gums, and with intestinal and uterine irritation. TREATMENT.-The management of deformities arising from abnormal muscular action should differ with the cause of the disturbance of muscular equilibrium. If it is impaired function that causes the distortion the weakened muscles should be strengthened by systematic exercise, elec- tricity, massage, and hypodermic injections of Strychnia, and by remedies directed to the promotion of the nervous supply. Brain or spinal cord disease should be sought for and, if possible, removed. After efforts to strengthen the paretic muscles have proved unavailing, their action may be supplemented by elastic tension or some form of mechanical support. Mechanical appliances tend to do harm if they entirely substitute the action of the weak muscles, because they remove the stimulus to exertion. Hence, the early treatment should be such as will encourage the development of power. If this is found impracticable, mechanical agencies to aid, but not to substitute, are a proper resort. Muscular contraction from syphilis, gout, and rheumatism can often be relieved by iodide of potassium, mercury, colchicum, morphia or atropia hypodermically, alkalies, massage, Turkish baths, and similar measures. Spastic contraction from cerebral or spinal disease is to be treated by the proper remedies for the lesion there existing; and that due to abnormal position or disuse, by restoring the function to the Osseous or other struc- tures primarily involved. Passive motion will often be all that is re- quired to give suppleness to the stiffened muscles around an impaired ioint. J Repeated stretching by manipulation, or continuous stretching by weights, elastic extension, or mechanical apparatus adjusted with screws will often overcome muscular rigidity and deformity. The removal of the source of peripheral irritation has often been promptly followed by relief of the muscular contraction or paresis. Tonic spasm of the masseter MUSCULAR P A R A LY SIS, CONTRACTION, ETC. 173 muscle has been quickly cured by extracting a wisdom tooth occupying an abnormal position in the alveolus. When the nervous irritation is central and cannot be removed, stretching or excision of a portion of the nerve-trunk supplying the contracted muscle may be useful in curing deformity and relieving the pain which often accompanies the condition of muscular spasm. It is not impossible that cases may occur in which it would be good surgery to trephine the skull and remove the cortical brain centre. When ordinary measures have been unsuccessful in curing deformity due to muscular contraction the patient should be subjected to division of the displacing muscle. This operation is done subcutaneously and con- sists in cutting through the belly or tendon of the muscle with a narrow, short-blade knife called a tenotome. Division of the muscular fibres is myotomy, division of the tendon, tenotomy; but the latter term is sometimes used to include division of muscles and fascias as well as of tendons. It is usually better to cut the tendon than the muscle, if a choice is possible, since the muscular gap is repaired by fibrous tisssue and not by muscle, while the two ends of the divided tendon are united by tissue almost, if not quite, identical with tendinous structure. The operation practically inserts a piece of new tendon in the gap and thus lengthens the muscle. If the tendon is so short as to be inaccessible, the muscular belly may be divided. Tenotomy should not usually be performed if the deformity depends upon palsy of the opposing muscles, nor if the deformity can be over- . by moderate mechanical power applied by apparatus or by manual OI’Cé. In ophthalmic surgery tenotomy is sometimes performed when double vision is due to a strong muscle overbalancing a paretic one. Tenotome with round end and aseptic metal handle. The tenotome should have a short cutting edge and a rounded end Somewhat keen in order to divide the skin, but it should not be pointed. There is then no need of a preparatory incision of the skin with another instrument and no danger of the point injuring vessels. The shank of the knife should be strong, but slender to permit turning in the small Wound, and the handle so marked that the position of the cutting edge imbedded in the tissues can be determined. It is usually preferable to divide the tendon by inserting the tenotome under it and cutting toward the surface. This, however, is not a matter of much moment. - The operation is seldom followed by any untoward results. After the ºdge of the tendon or muscle has been determined by the thumb-nail of the left hand and while the parts are kept stretched and tense by an *Sistant, the operator slips the tenotome flatwise through the skin and 174 MUSCLES, TEN DO N S AN D B URSA. under the tendon. The edge of the knife is then turned against the rigid cord, which is completely divided by a sawing motion and separates, perhaps, with a snap, so as to leave a distinct gap under the skin. If this springing apart of the ends is not very evident some of the fibres of the tendon have escaped division, or other tendons, or some bands of con- tracted fascia require section. These must be searched for and cut. Then the knife is turned flatwise and withdrawn. As it is removed the surgeon presses the blood out after it in order that no air may enter the puncture. A gauze dressing is finally placed over the wound, which unites by first intention. The skin and instrument must be aseptic in this as in all Surgery. After tenotomy it is usual to bring the deformed member into good position at once by manipulation and retain it so by appropriate appa- ratus. Some authorities think it well to wait a few days before attempt- ing restitution of position, but this does not seem to me judicious. The operation is not done to stretch the parts, but to put the foot or limb in proper position and substitute a long tendon for a short one, and the forcible manipulation, if done at once, is painless, because the patient has not recovered from the anaesthetic. Tenotomy may at times be demanded for the relief of other conditions than spastic contractions, club foot, and similar deformities. In oblique fractures with great displacement tenotomy may be required to allow proper adjustment of the fragments. The tendon of Achilles is the one that is most likely to be cut for this reason. Recurring painful spasm of muscles about inflamed joints may sometimes justify such a pro- cedure. In performing tenotomy the vicinity of arteries and nerves must be recollected. The posterior tibial vessels and nerves near the inner border of the tendon of Achilles and the peroneal nerve just inside of the outer hamstring tendon are to be carefully avoided. It is fortunate that when tendons need to be cut they generally stand out in relief because of their tenseness and rigidity. This prominence can be made more marked by an assistant extending or flexing the joints. Hence, the risk of dividing other structures which are not tense, is reduced to a minimum. Small veins and arteries may be divided with impunity, because the wound is subcutaneous and pressure is readily applied. Care must always be taken not to puncture inadvertently with the point of the tenotome the skin on the opposite side of the limb. The finger of the Surgeon should be kept upon that surface to avert such an accident. CONTRACTION OF THE PALMAR FASCIA AND ITS DIGITAL § PROLONGATIONs. DEFINITION.—This seems to be the proper place to consider the peculiar flexion of the fingers which has been called Dupuytren's contraction. It is a contraction of the palmar fascia and its digital prolongations, not in- volving the flexor tendons, which is found especially in male patients beyond the middle period of life, and which seems to be associated with and caused by the gouty diathesis. SYMPTOMs.-The little, the ring, and the middle fingers are most fre- quently involved, though the other fingers and even the thumb may be similarly affected. The patient notices that during several years a finger CO N T R A CTION OF PA. L. M. A. R. F. A. S CIA. 175 becomes more and more flexed upon the palm, until even forcible exten- sion is impossible and the first and second phalanges are so bent that the last phalanx and nail are, perhaps, pressed against the surface of the palm.

The disease shows a markedly hereditary tendency, and according to recent investigations is evidently of a gouty etiology. Trau- matism has been thought to be a cause, but the history of the cases, the heredi- tary character of the affection, its ocur- rence in both hands with almost equal frequency, and its comparative infre- quency in females, who are known to be more free from gout than males, make injury a rather improbable etio- logical factor. The diagnosis of this affection from stiffness of the fingers due to arthritis or to inflammation about the tendons is readily made. Chronic changes in the skin and joints, preventing perfect Dissection of finger contraction, affect- extension of all the fingers, is seen in ing middle and ring fingers.

(ADAMs.) volvement in the great majority of cases of one or more of the fingers of the ulnar side of the hand, point unmistakably to contraction being in the palmar fascia. A similar contraction of the plantar fascia may occur, but it is very much more unusual than the disease in the hand. TREATMENT—In the early stages of the deformity friction, passive motion, and retention on a straight splint for a long time may prevent the increasing distortion, and, perhaps, restore the function of the finger. As the Cases usually present themselves operation and prolonged treatment by Šplints and passive motion are necessary. The contracted fascia and its digital prolongation should be freely divided by a small tenotome in- troduced between the skin and fascia at various points. The finger should be at once fully extended and kept in that position by a splint, which should be worn constantly for several weeks. Even after the splint is (. º lſ, ſilt tº §§i)} § i. h º §§ \º § \{ * W \ | * 176 MUSCLES, TEN DO NS AND BU R.S.A. dispensed with during the day it should be applied and worn at night. It has been recommended to dissect up a triangular flap of skin in order to cut away the tense fascia piecemeal, but the subcutaneous method of Adams described is usually efficient. *. FIG, 67.

If the open method is adopted the apex of the flap should be in the palm over the prominent band of contracted fascia, while the base should be made far enough forward on the finger to give access to the median and lateral digital bands, which may extend as far as the second phalanx. After these fibrous ridges have all been clipped away the cutaneous flap is sutured in its former position. THECAL CYST OR GANGLION. DEFINITION.—The term ganglion is frequently, though ill-advisedly, applied to cystic tumors connected with the sheaths of tendons. This name should be discarded, because it has, in another sense, become so intimately associated with the anatomy of the nervous system. SYMPTOMS.—This form of cystoma, or cystic tumor, is seldom found except in connection with the tendons about the wrist and ankle. In symptoms and treatment the disease much resembles chronic inflammation of the normally existing bursae, which will be described hereafter. The cause of these cysts is unknown, though they may be due to strain or some other form of traumatism. The simple cyst, which is most frequently seen on the radial side of the back of the wrist, occurs as a globular swelling situated over the carpus, smooth, elastic, quite tense, somewhat movable and unaccompanied by T H E C A L C Y ST.

There is no pain unless nerve pressure exists, but the tumor causes a feeling of weakness at the wrist. Authorities differ as to whether such cysts are developed upon the sheath of the tendon, or are localized dilata- tions of the sheath cavity containing the synovial fluid of the sheath more or less altered in character. If formed in the latter way, the orifice of communication probably becomes occluded during the progress of the tumor, for, as a rule, the cyst does not seem to connect with the interior of the sheath. The compound ganglion, as the other variety is called, is more fre- quently found connected with the flexor tendons, and is a general dilata- tion of the sheath cavity, which may involve several tendons. This tumor, though a cystoma, and though called a compound ganglion, has not, as a rule, the multilocular character of compound cysts. The term compound is applied to it rather because of its being a more complicated and more troublesome affection than the simple ganglion just described. It is an irregular, fluctuating tumor, often giving on manipulation a creaking Sound and a peculiar crepitant sensation to the finger of the examiner. It contains synovial fluid, which may be dark or bloody, and in which are frequently found floating many small bodies, resembling rice-grains. It is these seed-like bodies which give rise to the crepitation. They are little masses of lymph, probably derived from the cyst wall, which may present à roughened internal surface. The tumor is not painful, but when located in the palm of the hand, its most common situation, causes flexion and impaired motion of the finger. The tumor is not tensely filled, and it is easy to press the fluid from the palmar portion of the tumor upward, under the annular ligament, until the distention is exhibited at the wrist. Both forms of cystic tumor of the tendons may be found in the foot and other localities. In this connection must be mentioned the fact that in the knee, hand, elbow, and other joints there are occasionally met hernia- like protrusions of the synovial membrane of the joint cavity through the ligaments. These become distended with fluid, and cause some stiffness, though there need be no effusion into the joint proper. Surgical inter- ference with such tumors is very apt to be followed by general synovitis, unless asepsis is rigidly observed. TREATMENT:-The localized thecal cyst is treated by sudden pressure °ºusing, subcutaneous rupture, or by subcutaneous puncture and discis- *With a tenotome.

If this manoeuvre does not succeed, it is proper to introduce a tenotome obliquely through the skin at a short distance from the tumor, and then puncture the sac and cut the wall in various directions by means of the single cutaneous opening. The fluid is thus liberated into the cellular tissue, or pressed out through the cutaneous opening, and, as the sac is freely divided, there is little liability of its reforming. The old-fashioned method of striking the tumor with a heavy book is crude, and withal unsurgical, because severe contusions may be caused. The limb should be kept at rest after the operation, and firm pressure made by an elastic bandage, or by an ordinary bandage and compress for several days. The external application of blisters and iodine to such tumors is generally of no service. st If rupture or subcutaneous incision does not cure these simple thecal cysts, and they are the cause of sufficient disability to justify a more extended operation, it is proper to inject tincture of iodine, carbolic acid or other irritating fluid, to lay them open freely, and paint the interior with undiluted carbolic acid, or to excise them. These procedures are more serious in the order in which they are named, because there is a possibility, though scarcely a probability, of causing violent inflammation of the tendon and secondary impairment of function. If there is no communication between the cavity of the cyst and the sheath of the tendon, this danger is reduced to a minimum, but it is often impossible to distinguish the fact of such absence. Compound thecal cysts cause considerable interference with the use of fingers or toes, and, therefore, constitute a greater disability than the simple cysts. They are also more serious to treat, because of their free communication with the general synovial cavity of the sheath. Free incision, occasionally in more than one place, with complete evacuation of the seed-like bodies and absolute rest of the part, is probably the best treatment. Some operators prefer to use a trocar to withdraw the con- tents, and then, after washing out the cavity with antiseptics, inject iodine or some other irritant. As the danger of operation lies in putrefaction and burrowing of pus along the tendons, I am inclined to favor a free incision with aseptic or antiseptic dressings to small punctures or the use of Setons. INFLAMMATION OF A BURSA OR BURSITIS, AND BURSAL TUMoRS. PATHOLOGY..—In connection with affections of the tendons, diseases of the vesicular synovial membranes, or sacs called bursae, must be consid- ered. Bursae normally exist, as a rule, where a tendon or the integument slides over a bony prominence; but they may become advantageously developed wherever constant pressure and friction call for protection of the underlying structures. The normal bursae number, it is said, about one hundred and fifty, and are found principally in the extremities. The most important, surgically, are those found over the patella, olecranon, great trochanter, tuberosity of the ischium, and heads of the first and fifth metatarsal bones. The bursal sacs in the popliteal space, under the liga- ment of the patella, under the psoas and iliac tendons as they cross the pelvic brim, over the acromion, between the angle of the scapula and broad dorsal muscle, beneath the deltoid, and under the four-headed €X- tensor muscle of the leg, should be remembered. Inflammatory affections of these bursae, though somewhat unusual, are liable to occur, and may IN FLA M M A TI O N OF A B U R S.A.. 179 prove confusing to the surgeon. Occasionally a transmitted arterial impulse causes bursal tumors in some of these localities to bear a slight resemblance to aneurism. Adventitious bursae are often developed at the points of pressure in club-foot and other distortions, and, indeed, wherever the occupation of the man or woman causes more or less constant pressure. Bursitis, or inflammation of the bursal sac, may arise from injury or from constitutional conditions, such as gout, rheumatism, and syphilis. The inflammation may be acute or chronic, and may be followed by Sup- puration or by distention with dropsical effusions. SYMPTOMs.-Acute is not as common as chronic bursitis. The symp- toms are those of acute inflammation limited to the known situation of a bursal sac, with some distention of the Sac by increased effusion of fluid. A slight crepitation may at times be felt with the first symptoms of pain before swelling occurs. The immediately adjacent structures are oedema- tous, and there is often considerable constitutional disturbance. The sac, when distended with inflammatory fluids, forms a fluctuating tumor. Suppuration may be supposed to have occurred when high con- stitutional disturbance has persisted for some time, or there have been rigors. The pus may make its exit from the bursa, or suppurative in- flammation in the neighboring cellular tissue may occur without actual rupture of the sac until the skin and deep fascia covering the knee, for example, are completely undermined by the burrowing matter. In time neglected cases will point externally, leaving, perhaps, fistulous tracts or ulcerated openings. Sloughing of the tissues overlying a bursa may happen. Chronic bursitis is more usual, and is characterized by much less pain, perhaps a mere feeling of stiffness or weakness of a limb, and by marked distention and thickening of the sac until a smooth, fluctuating, more or less globular tumor is developed. - The serous fluid contained in the cystic tumor, for such it practically is, may be quite dark from disorganized blood-cells, and frequently ex- hibits rice-like or melon-seed bodies identical with those described in the Section on thecal cysts. The amount of fluid may exceed a half-dozen fluidounces. Sometimes the walls of a bursa undergo a chronic inflammatory change which, by thickening and deposit of lymph, converts the sac into a hard, fibrous-like tumor, with perhaps a small central cavity. The most frequent location of bursitis is the bursa lying over the pa- tella, which is frequently subjected to traumatic influences, especially in housemaids and others whose calling requires the kneeling posture. This bursa extends downward over the upper part of the ligament of the Paiella and thus receives many impacts that the patella itself escapes, for it is Well known that in kneeling much of the weight comes in the situa- tion ºf ligament of the patella and the head of the tibia and not on the patella itself. Bursitis is to be distinguished from arthritis of the adjacent joint by the localized nature of the swelling and fluctuation, the less interference With motion, the absence of the characteristic semi-flexed position due to *Vial effusion in joints, and the comparative ease with which the normal articular prominences can be seen. Synovitis of the knee-joint º the patella to float upon the effused fluid so that it is raised from i. º of the condyles of the femur. If the surgeon strikes with thr ºgers upon the skin over the patella he can feel the patella descend ”gh the fluid and come in contact with the femur. This test shows 180 MUSCLES, TEN DO NS AND BUR SAE. in cases of inflammation at the knee whether the swelling present is due to fluid below the patella and in the joint or to serous effusion above the bone in the bursa. Slight inflammation of the joint occasionally takes place as an accom- paniment of bursitis because of the proximity of tissues. If the bursa ruptures and allows pus to enter the joint, acute arthritis may readily result. TREATMENT.—The treatment of acute bursitis should be rest of the limb, accomplished by elevation and splints, and the application of ano- dyne or refrigerant lotions. Leeches may be of service. In subacute cases or in the earliest stage of acute inflammation a blister may be ap- plied. If suppuration is suspected an early and free incision followed by curetting is proper, because the danger of burrowing of pus and pro- tracted convalescence is great. It is probably preferable in patellar bur- sitis to make the incision a little to one side of the median line, in order that the cicatrix may not be so subject to pressure after cure has been obtained. Sloughing of soft parts and caries of the patella must be treated on general principles. If spontaneous evacuation of pus and burrowing have taken place before the case comes to the attendant, the sinuses must be laid open and all pouches must be washed out with betanaphthol or sublimate solution or carbolized water, and emptied by counter-openings or drainage. Chronic inflammation or dropsy of a bursa is to be treated by counter- irritation and elastic pressure. If this fails, as it usually will, tapping with a trocar or aspirator, followed by the injection of strong carbolic acid solutions or iodine tincture, or by pressure, should be adopted. Lay- ing open the sac and keeping it stuffed with antiseptic gauze, thus causing granulation and obliteration to occur, is an available method. After laying open the sac the interior may be mopped with some strong caustic, as carbolic or nitric acid. Solid bursal tumors must be dissected out. Care is required to avoid injuring the adjacent synovial lining of the joint. BUNION. When a normal or an adventitious bursa upon the toes becomes in- flamed the condition called bunion is said to exist. Bunions are usually secondary to displacement of and pressure upon the toes, arising from muscular and osseous derangement and the wearing of FIG. 70. ill-fitting shoes. The metacarpo-phalangeal joint of the great toe is the most frequent seat of bunion. This toe is very liable to a chronic subluxation at this joint, and thus becomes bent toward the middle line of the foot. Upon the prominence made at the distorted joint by the head of the metacarpal bone a bursa is developed by the pressure of the shoe. When this bursa, or the normal one situated nearer the plantar surface of the joint, becomes irritated and inflamed, a bunion exists. It is said that this deformity of the great toe is due Distortion of toe and g e tº robably punion.(Bryan, ) to wearing narrow and short shoes, but this is probably a. untrue, since marked subluxation is exceedingly com. mon in the lower classes, who do not take pride in exhibiting small feel. A more probable explanation is that of Key, who believes it due to exce" B U N IO N. 181 sive standing which, when the arch of the foot is weak, causes distortion because of the obliquity of the pressure upon the inner side of the sole. Tight shoes cause the development and the inflammation of the bursa, and thus lead to the bunion, but probably do not act as the primary cause of the deformity. Club-feet usually have bursae developed upon their prominences, but even if these bursae imflame they are seldom dignified by the special title bunion. The skin over a bunion may have a corn developed upon it, which, of course, increases the painfulness of the affection. A bunion may suppu- rate, leaving a foul ulcer or fistulous opening; may open into the joint cavity, causing arthritis and disorganization of the articulation; or may, in decrepit pa- FIG. 71. tients, be the starting-point of erysipelas or \ gangrene. The preventive treatment of bunion consists in maintaining the correct axis of the toe, and restoring it when deflection first oc- curs. The first is to be done by avoiding con- tinuous standing during youth, and wearing shoes with flat heels and broad soles, and al- most straight along the inner edge. The true § / Waukemphast pattern fulfils these indications. Á Restoration of a distorted toe may be accom- Æ plished by steel springs and elastic traction, so Aº arranged as to be worn constantly.

The formation of pus requires an incision, but in all operations in this region in old and debilitated patients it must be remembered that the circulation here is feeble, and that unhealthy inflammation and gangrene are not unusual after surgical interference. The treatment of bunion, then, is identical with that of inflamed bursae elsewhere. A radical cure can sometimes be effected by introducing a tenotome at * distance and cutting up the bursal sac, as is occasionally done in thecal ºysts. , Laying open the sac by a free incision or excising it may at times be justifiable operations. C H A P T E R XV. DISEASES AND INJURIES OF THE NERVO US CENTRES AND NERVES. DISEASES AND INJURIES OF THE BRAIN. Meningocele and Encephalocele. THESE are congenital tumors due to the protrusion of a portion of the meninges in the one case, and of a part of the encephalon and its cover- ings in the other case, through an opening in the cranial bones. The pro- trusion may occur at a suture, a fontanelle, or an abnormal orifice in the skull. The most common seats for such unusual tumors are the occipital and frontal regions. In pathology TIG. 72. these tumors resemble hydrorachis or bifid spine. A meningocele being a pouch of brain-membranes containing sub-arachnoid fluid, resembles a cystic tumor of ordinary kind. Encephalocele is often asso- ciated with other congenital mal- formations, and usually is more solid than the tumor just de- Meningocele. scribed. - As a fatal issue generally occurs in these congenital hernias of the brain and its membranes, encephalocele and meningocele are of little importance except that the surgeon must think of them when diagnosticating tumors of the head. Their partial or complete reducibility, their immobility, the location of the neck of the tumor upon the cranial bones, the variation in distention as the child is quiet or excited, and in encephalocele, the occasional ex- istence of pulsation, will aid in the diagnosis. Pressure, aspiration, ligation, and excision are methods of treatment indicated, but are in most instances valueless. º: 2:…ºs 2. N s Hydrocephalus. Hydrocephalus is a dropsical condition of the brain, consisting of an abundant accumulation of serous fluid in the ventricles or the arachnoid space, or in both. It is a chronic condition, usually occurring as a con- genital disease. Acute hydrocephalus, so called, is of different pathology; for the term is variously applied by authors to tubercular meningitis and to cerebral dropsy due to renal disease. The amount of fluid in chronic hydrocephalus varies from half a pint to several pints, and produces enlargement of the head, especially in the antero-posterior diameter, I N F L A M M ATION OF T H E B R A. IN . 183 spreading of the sutures and thinning of the cranial bones. The pecu- liar squareness of the cranium and relatively small face give the child a characteristic appearance. The intracranial pressure and want of brain development cause lack of intelligence, paralysis, convulsions, retinal changes, and other cerebral symptoms. There is apparently little pain felt by the infant. & The most improved remedies are mercury and iodide of potassium, which have at times seemed to yield good results. Early death follows hydrocephalus, as a rule, when the dropsy is great and situated in the ventricles. Dropsy located in the cerebral membranes has a more favor- able prognosis. Tapping the distended skull with the aspirator, whether or not followed by injections of dilute tincture of iodine, has not been very satisfactory. It is better to repeat the tapping than to attempt to evacuate all the serum at once, and the fluid should each time be drawn off slowly. The instrument should not be introduced in the median line of the sagittal suture because the superior longitudinal sinus would be punctured. The wide separation of the bones gives opportunity to pierce the cranium at one side of the median line. Moderate pressure by an elastic bandage may be employed after tapping, or even as an independent treatment. If convulsions occur during the progress of the disease, bromide of potassium is the proper remedy. Intentional puncture of the ventricles themselves has been done by Keen in a case of hydrocephalus. Death finally occurred after apparent benefit from the operation. INFLAMMATION OF THE BRAIN FROM SURGICAL CAUSEs. VARIETIES.–Inflammation of the cranial contents is termed encephali- tis. The pathological process may be located in the meninges or mem- branes (meningitis), in the nervous tissue composing the various parts of the brain (cerebritis), or may involve both structures (meningo-cere- britis). - These three conditions, therefore, are merely varieties of encephalitis or intracranial inflammation. It is rare to find severe meningitis with- Out Some involvement of the underlying brain substance; and, unless the Cerebritis is limited to the deep parts of the brain, local meningitis, at least, is a usual accompaniment of inflammation of the nerve tissue. Celebritis strictly should not include inflammation of the cerebellum, to Which the term cerebellitis ought to be applied. PATHoLOGY.-In meningitis inspection of the membranes shows vascular Sºgorgement of the dura mater and pia mater, cloudiness or opacity of the arachnoid, and greenish or yellowish lymph deposited upon and between the membranes. The arachnoid membrane and its cavity show with *t frequency the existence of pathological changes; but puriform lymph *d pus will be found smeared upon the dura mater or in the meshes of the pia mater if the inflammation reaches a high grade. The relative Pºon of these morbid deposits, as to the dura and pia mater, depends much upon the starting-point of the encephalitis. Thickening of the membranes occurs with the progress of inflammation. Cerebritis, and the term is used to signify inflammation of the cerebellum and pons as Well as of the cerebrum, is exhibited by increased vascularity, a change * Color from gray or white to a pinkish or dirty yellow or a leaden hue, 184 DI SEASES AND IN J U RIES OF N E R V OUs CENTREs. turbid serum in the ventricles, and softening of the nerve structure. If the disintegration continues pus will be formed, constituting a cerebral abscess, which may contain several fluidounces of fluid. CAUSES.—The causes of surgical encephalitis are fracture, caries, and necrosis of the skull involving directly or indirectly the cranial contents; wounds of the membranes; concussion, contusion, lacerations and other wounds of the brain; and pyaemia. SYMPTOMS.–The symptoms of meningitis and of cerebritis are not, as a rule, sufficiently distinct to make a differential diagnosis possible. Fortunately, their treatment would be identical in the majority of cases, even if such a diagnosis was made. Acute traumatic encephalitis gives rise to headache, pain, and elevation of surface temperature at the seat of injury, contracted pupils, intolerance of light and sounds, restlessness, delirium, general fever, full and frequent pulse, constipation and perhaps vomiting. As the disease progresses twitching of the muscles, strabismus, convulsions, stupor increasing to absolute coma, and relaxation of the sphincters of rectum and bladder supervene. Great circulatory depres- sion, as shown by feeble, irregular, and very frequent pulse, clammy sweating and dilated pupils proclaim serious involvement of the brain, which will, in all probability, speedily terminate in death. The paralytic symptoms are due usually to the exudation of inflammatory products, which cause a condition similar to compression from extravasation of blood in depressed fracture. Rigors occasionally happen and suggest the formation of an intracranial abscess or of pyaemic infection from inflam- mation having involved the diploic structure of the cranial bones. Sub- normal temperature is thought to be indicative of abscess. Acute encephalitis occurs in from one to three days after the receipt of injury, and usually leads the surgeon to believe that there has been a general injury to the brain in addition to the evident local lesion. In other words, symptoms of acute encephalitis generally mean contusion or laceration of one or more parts of the brain distant from the point of impact with the vulnerating body. Laceration by counter-stroke at the side opposite the injury is a not unusual factor in the etiology of acute inflammation. The condition occurring after injuries and called irritation of the brain is probably a minor degree of encephalitis affecting special regions of the brain substance. It is characterized by restlessness of the patient, who lies curled up on one side with his limbs flexed and his eyes tightly closed. If aroused from his semi-insensibility he shows a momentary mental irritability, and then relapses into a restless sort of sleep. Chronic encephalitis causes headache, vertigo, hebetude and intellectual dulness, insomnia, epileptiform seizures, choking of the optic disks or papillitis, paralysis, and coma. The symptoms are less violent than in acute inflammation, but are similar, though coming on insidiously and at a period varying from weeks to months. Tain at the seat of injury and a local rise in surface temperature are grave symptoms in old head in- Ull’I6S. J Death occurs in emcephalitis from pressure due to morbid deposits or from blood extravasated from diseased vessels; from destruction of ner- vous centres by softening or abscess; from interference with blood-supply by thrombosis, and from pyaemic injection of the general system. e A diagnosis between meningitis and cerebritis is, as a rule, impossible, because the two conditions are so frequently associated that we are not assured of the symptoms pertaining exclusively to each. If the local pain, IN F L A M M ATION OF T H E B F A IN . 185 the restlessness, nausea, and hyperaesthesia of the optic and auditory nerves are especially marked, it is probable that inflammation of the meninges is the prominent pathological change. Cerebritis is to be sus- pected if convulsions, jerking of the muscles, trembling, and sudden dis- turbances of the special senses are observed. The suspicion is strength- ened if the muscular symptoms are unilateral, and if coma and actual paralysis of one side rapidly occur. TREATMENT.-Acute inflammation of the brain requires active treat- ment. The entire scalp should be shaved to permit full examination for fracture, contusion, or other injury; the head should be elevated, cold should be applied to the cranium by means of a bladder or rubber bag containing cracked ice, or by means of cold water passing through a coil of tubing encircling the head several times, and the patient should be kept in a darkened and quiet room. If the pulse is hard and frequent, the face flushed, and the carotid arteries evidently carrying a large amount of blood to the head, venesection at the bend of the arm is valu- able. The bleeding should be supplemented by free purging, large doses of bromide of potassium (3iij to 3v in twenty-four hours) and cardiac de- pressants, such as tincture of aconite root (m.j to iij every two or three hours), or tincture of veratrum viride (m.j to iij every two or three hours). The best purgatives are calomel and jalap (gr. v to x each), or two or three compound cathartic pills. Many do not require bleeding, but are judiciously treated by the other remedies mentioned, with or without wet cupping at the nape of the neck. Digital or instrumental pressure upon the carotid arteries has been suggested as a means of diminishing the intracranial circulation. Some high authorities advise the use of mer- curials and opiates to combat encephalitis, and give calomel (gr. 4) and morphia (gr. Tº) every few hours, for their antiphlogistic and quieting effect. I have been accustomed rather to rely upon the revulsive action of purgative doses of mercury and other drugs, and the cerebral anaemia and quiet produced by large doses of bromide of potassium. When there are great restlessness and brain irritability, morphia in moderate doses is indicated. Chloral (gr. v to xv) or hyoscine hydrobromate (gr. Thr) may be employed to meet this symptom. The diet should be limited in quantity, and restricted to milk or other non-stimulating food. In the later stages, when exudation has probably occurred, blisters may be used locally, and iodide of potassium (gr. v to x) and mercury (green iodide, gr. # to #) given internally several times in the twenty-four hours. When great depression supervenes some alcoholic stimulant may be employed, but usually this stage presages death, which cannot be, and per- haps could not, have been averted. In all cases the bladder should be Watched, and catheterized if the urine is not passed. The patient is per- haps unconscious, and the attendants may neglect to call attention to the fact that no urine has been passed unless the surgeon makes inquiries. Subacute and chronic encephalitis demand similar though less active *atment. The measures mentioned for the later stages of the acute disease are especially applicable. Mercury, iodide and bromide of potas- sium, blisters, and laxatives are usually employed. If an acute inflam- **on is engrafted upon a chronic one, it must be met by active and V**ous measures, as though it had been an acute affection primarily. In all gases of suspected brain disease the condition of the urine should be *Yºstigated, since renal changes will induce uraemic symptoms, simu- *ing intracranial inflammation. Patients who have recovered from encephalitis due to surgical causes, 186 I) ISE A SES AND IN J U RIES OF N E R V O U S CENTRE S. may suffer for many weeks from vertigo, headache, sleeplessness, mental aberration, and other sequels pointing to deranged nervous activity. These symptoms are to be combated by the long-continued use of altera- tives, such as the preparations of mercury and iodine, and by the tem- porary administration of bromide of potassium, chloral hydrate, and similar medicines. Chronic encephalitis is a not uncommon symptom of tertiary syphilis, and is frequently associated with syphilitic inflammation of the spinal cord. Mercury (green iodide gr. j to gr. ij, during twenty-four hours), with iodide of potassium (gr. lxxv to gr. c in twenty-four hours), is especially indicated in such cases. All chronic cases should be subjected to antisyphilitic treatment, as should all cases of supposed brain tumor. OPERATIVE TREATMENT.--When it is possible to locate the exact seat of the intracranial inflammation, operative interference may sometimes be undertaken with the hope of removing the spicule of bone or the foreign body which has caused and is keeping up the morbid process, or with the expectation of evacuating the collection of blood or pus which is threatening the life of the patient. Trephining the skull, incising the membranes and puncturing the brain tissue are the modes of operation that may be adopted. Such procedures are much more frequently justifiable in chronic than in acute encephalitis, because the former is more likely to be local in its causation and in its lesions, and, therefore, more accessible by operation. The reader must recollect that in this connection I am speaking of trephining as a mode of treating eacisting traumatic inflammation of the brain, and not of preven- tive trephining, which is undertaken to prevent the consequences of punc- tured and other forms of fracture of the cranium. The method of using the trephine will be described under fractures of the skull. Operation may be done to give exit to an extravasation of blood or a purulent collection within the cranial cavity; to remove a foreign body, such as a bullet, supposed to be buried in the brain or membranes, and to endeavor to find and get rid of the cause of an inflammation which is suspected to be due to a splintered condition of the inner table or to localized bone disease. t Collections of pus or of blood may lie between the bones and membranes (subcranial), in natural or abnormal cavities formed between layers of membranes (intermeningeal), or in the substance and ventricles of the brain (cerebral). Subcranial and cerebral extravasations and abscesses are usually circumscribed, and, therefore, more amenable to operative treatment than intermeningeal collections, which are, as a rule, diffused. LOCALIZATION OF BRAIN LESIONS.–Until within a few years the Sur- geon had little to guide him in attempts at ascertaining the precise loca: tion of cerebral lesions; and, therefore, operations upon the skull and brain were seldom justifiable in cases where there was no fissure or open- ing in the cranium. A localized puffy swelling of the scalp, or separation of the pericranium exposing yellowish or dry bone, with hemiplegia of the opposite side of the body, and especially if rigors had occurred, might induce a bold operator to trephine and endeavor to evacuate the abscess; but there were no rules founded on physiological and clinical observation to guide him in the less obscure cases. The recent study of cerebral localization by Ferrier, Charcot, Horsley, and other neurologists, however, has made it possible to determine the Site of many lesions of the cerebral cortex, or surface, by the local tempera- ture and the character of the paralytic and other nervous symptoms. I N F L A M M ATION OF T H E B R A IN. 187 The special symptoms belonging to irritative and destructive lesions of the various parts of the interior of the brain have not yet been established with much accuracy; and, indeed, the exact locality of many of the nervous centres upon the surface is still doubtful. Nevertheless, enough has been done in this direction to aid the surgeon very much in determin- ing, from the symptoms, where to apply the trephine in suspected abscess, extravasation, or impacted splinters of bone.

V J U S Diagram of skull, showing relation of convolutions to bones. The relation of the important landmarks of the brain to the external conformation of the skull is found in the figures. It is important to distinguish lesions of the surface of the cerebral hemispheres from those of the interior of the brain, because the former, unless at the base, are more easily reached by operation. Cortical lesions Cause usually not a loss of motion of an entire side (hemiplegia), but a paralysis of only a special group of muscles, as of the hand, forearm, or leg (monoplegia), and there is quite frequently early rigidity of the same muscles. Jacksonian epilepsy, or convulsive action of a single group of muscles, as of a thumb, occurring alone, or occurring as a prelude to a general epileptiform convulsion, gives indication that there is a lesion of that particular cortical centre, and points to the advisability of an explora- ºry, operation in that region.

Recent investigations go, however, much further than this, and locate with considerable certainty centres governing many special motions. From this knowledge it is possible to diagnosticate with a great degree of certainty the location of the inflammatory process which is pro- ducing the symptoms in a given case.

A M M ATION OF T H E B F A IN. 189 alone (brachial monoplegia) indicates disease of the upper part of the ascending frontal convolutions of the opposite side. Here then would be the place to trephine, if the other symptoms rendered the occurrence of abscess or intra-cranial bleeding probable. It is always important to determine upon the shaved head the location of the fissure of Rolando before undertaking any operative procedure based on cerebral localization. This may not be necessary if an external injury or scar indicates the probable seat of lesion. This fissure has its upper end 50 or 55 millimetres behind the bregma or junction of the in- terparietal and coroneal sutures, but does not quite reach the middle line of the skull. The bregma is found by drawing a vertical plane through the two external auditory openings. The lower end of the Rolandic fis- sure is about six centimetres above and a little behind the external audi- tory canal. It makes an angle of 67 degrees with the median line drawn from the glabella, or smooth spot at the root of the nose, to the external occipital protuberance, or inion, and has its upper end beginning on a line with a spot situated 55 ºr per cent. of the total distance from the glabella to the inion.

When paralysis or convulsive movements occur in connection with disease of the sensory region, operative interference is improper, since the pathological change is not limited to the sensory centres, but involves the motor region. An exploratory trephining, if properly carried out with antiseptic precau- tions, is so devoid of danger that many surgeons would operate notwith- standing the co-existence of motor and sensory symptoms. Paralysis on the same side as the injury of the head should be consid- ered an indication against operation at the point of injury, because there is probably a lesion at the opposite side of the brain, due to counter-stroke. Again, very profound loss of motion points to non-interference, because it is likely that the injury involves deeper tissues than the cortical cen- tres of motion. Paralysis of the cranial nerves, Cheyne-Stokes respira- tion, choked disk, and symptoms referable to injury of the base of the brain contra-indicate surgical procedures.’ FIG. 7S.

The occurrence of aphasia betokens an abscess, pressure from a clot, or injury from a spicule of bone, located near the base of the third frontal convolution and the island of Reil, and usually on the left side. Right-sided loss of motion in addition to the aphasia, while showing a more extensive lesion, perhaps, fixes the lesion at the left side of the brain. In such cases trephining gives a reasonable hope of reaching and remov- ing the cause of the threatening symptoms, When the symptoms and principles just discussed furnish sufficiently clear evidence to satisfy the surgeon as to the probable seat of the lesion, IN J U R IB S OF T H E B F A IN . 191 it is proper, if the case present a serious outlook, to trephine without delay. Delay is dangerous if the lesion is chronic encephalitis, with abscess; and equally so if there are symptoms of a large extravasation of blood, or of a local inflammation due to spicules of bone. After the skull has been bored the pus or blood will be evacuated if it lies between the bone and dura mater. If none is found, and the dura bulges into the opening and does not show pulsation an incision should be made through this membrane with the object of reaching any collection beneath it. If the symptoms of cerebral abscess have been very characteristic and death is imminent it is justifiable to puncture the brain in various directions with an aspirator needle or grooved direc- tor in order to reach the purulent deposit. In the event of discovering a large hemorrhagic effusion from a meningeal vessel, torsion of the artery may be required. If this fails a tre- phine may be again applied over the course of the vessel, and a ligature applied after removal of the disk of bone.

There are now on record numerous instances of trephining and brain puncture for extrava- sated blood, cerebral abscess and for the removal of brain tumors, which have been followed by recovery. INJURIES OF THE BRAIN. Under this heading I shall discuss wounds, concussion, and compression of the brain, leaving fractures of the skull to be treated in the chapter on Diseases and Injuries of Bone. SCALP Wounds.--It is usual for writers to devote a section or two in this connection to descriptions of scalp wounds. The proximity of the brain to the part wounded and the possibility of the vulnerating force having fractured the skull or caused brain injury at the time the scalp wound was inflicted should make the surgeon cautious in watching symp- toms and careful in the treatment of scalp wounds; but there is nothing intrinsically special in such injuries. They should be rendered aseptic and be approximated by sutures, and their complications, such as hemor- rhage, abscess, and erysipelas met as in ordinary wounds. The pin suture is a favorite of mine as it controls the bleeding, which is apt to be profuse because of the great vascularity of the scalp. It is easy, however, to con- 192 DIS E A SES AND IN J U RIES OF NERVO US CENTRES. trol hemorrhage by a tight bandage around the head, for the cranium gives a firm surface against which to make pressure. Wounds of THE BRAIN.—Wounds of the brain are usually accom- panied by fracture of the skull. Such is not the case, however, when laceration from sudden jarring occurs, or when punctures are received through the fontanelles or other openings in or between the bones. Wounds of the anterior and superior region are less serious than those of the base or posterior part of the encephalon. Very serious wounds result when fragments of a fractured cranial bone are driven into the meninges and brain substance. Gunshot wounds are also very destructive. The symptoms of brain wounds depend upon the situation of the injury and the amount of nervous tissue involved, as is easily understood from the foregoing remarks on cerebral localization. Shock, paralysis, and perhaps unconsciousness, in varying degrees, are the early symptoms of brain wounds, and are soon followed by local or general inflammation of the brain. Portions of brain material may be cut off by the surgeon or carried away by extensive injury and recovery be not only possible but even probable if the parts are kept or soon rendered aseptic. TREATMENT.-The treatment of brain wounds is embodied in two pre- cepts: Remove the foreign body, if any exists and it can be withdrawn without inflicting grave additional injury; and prevent, or at least limit, the secondary inflammation that is liable to follow the wound, by antisepsis and most thorough drainage. Probing brain wounds to discover the locality of a bullet or any missile should be done only with great care and with aseptic precautions. A large- headed probe of aluminium is the best instrument and should be allowed to follow the bullet-track by its own weight when the patient's head is so placed that gravity will carry the probe in the course of the wound. Trephining to give access to the foreign body is proper, and thorough drainage by means of rubber tubes is essential to cure. Measures calcu- lated to combat encephalitis should be employed. Secondary abscess must be diagnosticated and treated as described in the section on cerebral inflammation. Recent observation has shown that the brain can be punctured, incised and excised with a great degree of impunity, provided the internal ganglia are undisturbed and these operations are rigidly aseptic. It occasionally happens that through the opening in the membranes and skull there occurs during the progress of inflammation a fungoid protru- sion of brain matter mingled with lymph, pus and blood. This consti- tutes the condition called hernia, or fungus, of the brain, which is liable to continue until either exhaustion or the damage done the nervous centres by inflammation causes a fatal issue. Fungus of the brain demands no special line of treatment; but clean- liness in removing the discharges and the use of antiseptic dressings are proper. Moderate pressure upon the mass may be attempted, but it is liable to do harm by causing retention of the secretions within the cranial cavity. To cut off the protuberance is not infrequently good surgery. The possibility of fungus of the brain occurring must be remembered when operations are performed which are liable to divide the dura mater; hence, the dura mater should be carefully sutured after the removal of tumors of the brain. It is understood that provision for drainage must be made through the dural incisions, by tubes, or strands of catgut or horsehair. C O N C USS I O N OF TH E B R A. IN. 193 CONCUSSION, CONTUSION, AND LACERATION OF THE BRAIN. DEFINITION.—The term concussion has long been used to designate the symptoms which follow vibration of the brain consequent upon blows received directly upon the skull or transmitted there through the spinal column. It was supposed that a man might die instantly from concussion of the brain, without receiving any physical lesion of the brain substance. PATHOLOGY.—This assumption I believe to be false, for fatal cases of so-called concussion of the brain exhibit, on careful examination, con- tusion or laceration of the brain, separation of the dura mater from the bones, compression from clot, or some distinct lesion of the contents of the cranium. Death in cases in which no such evidence of brain injury has been found, has not infrequently been attributed to concussion of the brain, without an investigation of the spinal cord and heart. Fatal changes would probably have been found there. I admit the possibility of the vibration causing a molecular change in the nervous cells, the capillaries, or the cerebro-spinal fluid, which could not be appreciated by our ordinary methods of investigation, and which still might be capable of producing the symptoms found in slight concussion; but when death occurs in cases denominated concussion of the brain, I believe that dis- tinct lesions, if carefully sought for, will always be found. If a vessel containing jelly, of the consistence of the brain and contain- ing similar cavities, was forcibly struck, fissures could easily be produced in the mass by irregular transmission of the vibrations of force. So, I believe, do lacerations and contusions of the non-homogeneous brain OCCUll’. In my opinion, then, concussion of the brain is not a functional condi- tion, but is used to designate organic changes. The term, therefore, should be discarded for contusion or laceration. Cases of slight concussion very much resemble a similar degree of that obscure condition called shock. It is, perhaps, possible that a sudden moderate force applied to the head, containing cerebro-spinal and sympa- thetic nerve centres, causes pallor, vertigo, and confusion of ideas by the same pathological change that occurs when peripheral nerves are injured. When greater violence is offered to the brain it is to be expected that, in addition to the condition of shock, symptoms will be presented due to the laceration which necessarily occurs because of the jelly-like consist- ence of the brain. This view is partially substantiated by the statement of some surgeons that, in all instances of concussion severe enough to cause unconsciousness, serious symptoms are liable to ensue. This theory would place under the head of shock those temporary symptoms now called slight concussion, and would class all other instances of brain injury of a similar character as contusion or laceration of the brain. Lacerations and contusions of the brain may be multiple, giving rise to numerous minute extravasations of blood, scattered throughout the brain and scarcely distinguishable from the normal vascular points seen on Section. On the other hand, hemorrhage from the torn vessels may be so great and so diffused as to produce symptoms of compression of the brain, thus greatly obscuring the diagnosis. The irregularity of the base of the skull causes laceration to occur most frequently in the corresponding region of the encephalon. CAUSES.–Direct violence to the head, or force applied to the legs or buttocks and transmitted through the spinal column to the cranial bones, I 3 194 DISE ASES AND IN J U R IES OF NERVO US CENTREs. are the causes of contusions and laceration of the brain. A blow on one part of the cranium will often give rise to laceration of the brain at the oppo- site side without there being any marked injury to the cerebral tissue im- mediately underlying the bone struck. This is due to the soft consistency of the brain, and is termed contusion by counter-stroke. SYMPTOMS.—When a slight blow has been received by the brain the patient at once becomes giddy, is confused in his ideas, feels weak, staggers and perhaps would fall if not steadied by grasping some neighboring sup- port. At the same time his face becomes pallid, and his heart's action feeble. There is a feeling of nausea, and vomiting sometimes actually occurs. These slight cases do not exhibit actual unconsciousness, but the patient is “stunned,” and for a moment is not able to collect his thoughts. He in a moment promptly returns to his normal state. This is the condition in which it is possible, perhaps, that no laceration of mervous structure or blood vessel occurs; and such cases are those that resemble surgical shock of slight severity. The violent shaking of the brain caused by the application of a severe force is followed by symptoms of gravity, which are due, in my opinion, to the production of contusion or laceration of the brain or its membranes. The patient is almost, but, as a rule, not completely, unconscious; lies motionless with a cold, pallid skin, has a feeble, fluttering pulse and heart, and sometimes passes urine and feces involuntarily. The insensi- bility is not a complete coma, for usually the patient can be roused by loud questioning to utter a monosyllable or a groan. The pupils vary in different cases as to contraction or dilatation, and the two eyes may not be alike in this respect. Usually the pupils react to the stimulus of light. The breathing is quiet, though it may be feeble and shallow ; there is no hemiplegia, and the limbs if pricked with a pin will be withdrawn, though probably in a lazy manner. Vomiting is liable to occur as the patient begins to react from the semi-unconscious condition which has immediately succeeded the injury. Convulsions sometimes take place after such cere- bral injuries. The location of the contusion is an important factor in the determination of special symptoms. The symptoms just described may last a few hours or a day, before signs of recovery or of progressive in- flammation supervene. When return to health is to ensue, the symptoms of brain contusion slowly subside and the patient’s functions assume their normal condition. It often happens, however, that headache, vertigo, impaired memory, and other cerebral sequelae remain. . When the issue of the injury is to be an unfavarable one, the patient either sinks into a comatose state, without reacting, or, if he does react, soon presents the characteristic symptoms of encephalitis. The prognosis is grave in all cases of contusion of the brain, because it is impossible to define accurately the extent of the lesion, and because even slight lacerations and contusions are liable to impair the mental functions and the special senses. All injuries producing vibration or con- cussion of the brain that are followed by the semi-unconsciousness men- tioned are serious, because there is organic lesion of the brain tissue. Some writers speak of three stages of concussion of the brain—namely: collapse, reaction, and inflammation. I object to this division, and, indeed, ignore entirely the term concussion of the brain, since I do not believe in the existence of a functional dis- turbance of the brain without organic lesion. Concussion of a muscle or bone causes a definite lesion called contusion, laceration, fracture; so concussion of the brain, if it produces symptoms, must cause an organic C O M P R E SSI O N OF T H E B R A. I. N. 195 lesion. In cases subjected to careful autopsy such lesions are found, though it is possible that instances may occur in which organic change is too slight to be appreciated by our present knowledge and means of in- vestigation. Concussion or vibration of the brain should not be considered a condi- tion of disease of the brain, but merely a cause of contusion and lacera- tion of the organ. Let the term concussion, as usually employed, be dropped, and contusion or laceration substituted, and such symptoms as those I have been describing will be better understood and better treated. The three stages of concussion, called the stage of collapse, that of reaction, and that of inflammation, are relics of the old nomenclature, and are un- necessary. If concussion is synonymous with contusion or laceration, as it should be, the occurrence of reactionary and inflammatory phenomena is readily intelligible. TREATMENT.-As the symptoms are those of shock, combined with those of brain contusion and laceration, the treatment is obviously clear. At first absolute quiet in the supine position, with the feet elevated slightly and the head low, should be enjoined. A darkened room and an oppor- tunity to sleep should be afforded. Stimulants will rarely be needed, and should be avoided if possible; because, after the shock of injury has passed away, cerebral excitation and plethora will tend to produce hem- orrhage from the torn vessels, and to set up inflammatory engorgement. Agents, such as ammonia, that stimulate momentarily, are preferable to the more lasting alcoholic preparations. External applications of heat or of mustard to the general surface may be available to relieve the depression. When the pulse shows increasing strength, or there is evi- dence in the reddening of the skin that reaction has commenced, the sur- geon must adopt measures to prevent the occurrence of cerebral inflamma- tion. The head should be elevated, cold applied locally, and bromide of potassium, purgatives, and other remedies employed in the manner described when speaking of inflammation of the brain from surgical causes. Even bloodletting may be required, though in the early hours after the injury such treatment might prove fatal. It requires the exercise of great judg- ment to manage such cases. The measures appropriate for the first few hours' treatment of contusion of the brain are diametrically opposed to the line of treatment required after reaction has been induced. It is a nice question to know when the change should be made. - All cases of contusion of the brain, however slight, require surgical Supervision for a long time. Indiscretions in mental work, in diet, or in physical exercise may be very deleterious. COMPRESSION OF THE BRAIN. DEFINITION.—Compression of the brain is said to exist when pathologi- cal lesions or changes exert such pressure upon the organ as to displace the cerebral substance or cause flattening. The symptoms are probably due, to a great extent at least, to the pressure impeding cerebrai circula- tion and causing a local deficiency of blood supply. It is certainly not likely that the amount of force exerted by extravasated blood, which so often gives rise to compression symptoms, is sufficient actually to compress and condense the brain substance. It would require comparatively little * however, to interfere with the calibre of the capillary blood- vessels. 196 DISE A SES AND IN J U R IES OF NERV OU S CENTRES. CAUSES.–The causes of compression of the brain are: 1. Extravasa- tion of blood upon the surface or in the interior of the brain. 2. Fractures of the skull, accompanied by depression of the fragments. 3. Foreign bodies driven through the skull upon the surface of or into the brain. 4. Inflammatory deposits of serum, lymph, or pus. In the second and third instances bleeding, due to laceration accompanying the fracture or wound, has frequently much to do with the occurrence of compression. A comparatively sudden pressure seems to be requisite to produce com- pression symptoms. If blood, for example, be slowly extravasated, the brain seems to accommodate itself to its new relations, unless the amount of blood be great. SYMPTOMS.-A patient suffering with compression of the brain is dead to external impressions, but the organic functions of respiration and circu- lation continue. He lies on his back, totally unconscious and immovable, with pupils unaffected by light, and one or both of them usually moder- ately or considerably dilated. The respiration is slow (ten to sixteen per minute), snoring, and accompanied by a peculiar whiff or puffing out of the cheek at the corner of the mouth. The stertor is due to paralysis of the palate muscles. It may be greatly diminished by turning the patient on his side, so that the relaxed soft palate will not hang unsupported in the current of air. The puffing out of the cheek is due to loss of power in the buccal muscles. The pulse is slow and rather full, beating perhaps not more than forty or fifty times in a minute. The urine is retained until the paralyzed bladder becomes so distended that there is a dribbling overflow. Constipation, followed by relaxation of the anal sphincter and consequent incontinence of feces, is often found. Hemiplegia of the side opposite the injury is usual. This cannot be determined in cases where reflex sensibility is destroyed, unless it is evident from the distortion of the face. The condition of the pupils and the extent and character of the paralysis depend upon the situation of the compressing lesion. The group of symptoms given are those found in typical cases of compression, and are those of cerebral apoplexy, which is a form of compression. Symptoms of compression due to depressed bone or to foreign bodies lodged in the brain arise immediately after the receipt of injury. Extrav- asation of blood, unless profuse, causes a gradual supervention of symp- toms, while compression from inflammatory products appears only at a later period. It is probable that a factor in many cases of compression from depressed fracture is the concomitant occurrence of inflammation, whose symptoms are blended with those due to the pressure which often is too slight to cause in itself serious symptoms. If the pressure is not relieved by treatment, and the cerebral mass fails to accommodate itself to the new relation of parts, coma deepens, the organic functions become gradually involved and death occurs. The time occupied in the fatal invasion and destruction of these functions is usually a few days, though it may extend through weeks. DIAGNOSIS.—Typical cases of compression of the brain are readily dis- tinguished from contusion or laceration (so-called concussion) of the brain of moderate severity. If a laceration or contusion is sufficient to cause much hemorrhage, however, compression symptoms will coexist and com- plicate the diagnosis. So, on the other hand, laceration and contusion of the brain substance is liable to result from the same force that produces a depressed fracture and a consequent depression. Hence, it is often impos- sible to determine accurately the pathological lesion. C O M P R ESS I O N OF T H E B R A IN . 197 The points upon which a differential diagnosis may be founded in uncom- plicated cases are given in the following table: Compression. 1.

Respiration quiet. Pulse frequent and feeble. Sometimes vomiting. Incontinence of urine and feces. No paralysis. Pupils react somewhat to light. Deglutition possible. In the absence of a history or the patient before unconsciousness occurred, it is frequently difficult and sometimes impossible to discriminate between coma due to compression of the brain, alcoholic or narcotic poisoning, uraemia, apoplexy, sunstroke, and hysteria. An unconscious man with bruises upon the head, picked up in the streets, may be suffer- ing from brain compression due to injuries received while intoxicated; or may have fallen from an elevation because of an apopletic seizure or sunstroke, and thus have sustained secondarily a depressed fracture of the skull. In such cases the head should be shaved, and careful examination made for signs of injury to the skull; the urine should be examined for albumin and tube casts, alcohol, opium, and other poisons; the tempera- ture should be taken, and tests of electro-muscular sensibility and con- tractility should be instituted. The ophthalmoscope will sometimes be of service in disclosing albu- minuric retinitis and choked disk, or other changes in the fundus. The existence of paralysis in compression of the brain usually serves to distinguish it from the conditions named, with the exception of apoplexy. It is the compression produced by the hemorrhage in an apoplectic seizure that induces many of the symptoms; hence, a diagnosis is impossible unless the history and evidences of injury afford direct information. The treatment, however, is identical in such conditions. The odor of poisons, the contracted pupils of opium narcosis, the oedema of chronic Bright's disease, the high temperature of sunstroke, and the sex in hysteria will aid in the differentiation of some obscure cases. Such evidence is fallible, however, and it may be that the surgeon’s opinion must be suspended until the progress of the case clears up the obscurity. º: patient may indeed be suffering from two conditions at the same III) e. ... TREATMENT—Compression of the brain demands removal of the cause if this can be done without inflicting more serious brain injury. Depressed bone should be elevated; foreign bodies extracted; pus evacuated by trephining ; extravasated blood removed and further bleeding prevented by opening the skull, turning out the clots, and tying the vessel. These 9perative procedures are proper only when the existence of compression is clearly established, and its cause and location known. Investigations of the localization of cerebral lesions and improved methods of treating 198 DISE A SES AND IN J U RIES OF NE R Vous CENTREs. wounds have made such operations more frequently justifiable than was formerly the case. When such measures are not deemed wise, the patient should be treated on the general principles laid down for the prevention of encephalitis. Purgatives, bromide of potassium, iodine and its compounds, mercury, and bloodletting are the remedies to be employed. If hemorrhage is supposed to be the cause of compression, the head should be elevated. Enemas may be given to empty the lower bowel. The catheter must be introduced twice or thrice daily to withdraw the urine from the paralyzed bladder. TUMoRS OF THE BRAIN. Tumors of the brain may be fibromas, sarcomas, carcinomas, cystic tumors, etc. They may have their seat between the dura and the cerebral convolutions, or they may be more or less deeply imbedded within the brain tissue. The symptoms depend upon the position of the growth and its size. Epileptic convulsions, local paralyses and spasms, choked disks, aphasia, and intellectual aberrations all occur. It is the simultaneous or consecutive occurrence of these and other symptoms which enables the neurologist to localize the position of the growth. If such a tumor does not involve the basal ganglia, nor occupy a position so far under the base of the brain as to make access impossible, it is proper to attempt its re- moval by opening the skull and excising it. Such operations should be done with the strictest antiseptic precautions and by means of a large trephine and gnawing forceps. Provision must be made for drainage, even if the opened dura mater is subsequently sutured, as it usually should be, and if the button of bone cut out by the trephine is replaced before the scalp flap is sutured into position. The details of such opera- tions will be found in the various monographs which have recently been written on this subject. - Growths situated at some distance below the surface of the convolu- tions are not accessible until the surgeon has incised the brain tissue. This procedure is justifiable, if punctures carefully made with a probe or grooved director give evidence of a tumor below the surface. When the clinical history of the patient shows evidence of multiple brain tumors or of a tumor which is evidently a secondary malignant growth, it is scarcely proper to attempt removal. The diagnosis in cases of suspected brain tumor is very difficult and requires the most careful consideration of the skilled neurologist. It is probably true that surgeons usually have not the special knowledge which enables them to make an absolute diagnosis as to location. Hence, examination of the eye grounds, of the paralytic symptoms, and of the epileptiform seizures should be made by those who are trained to such matters. When a reasonable diagnosis has been made by such expert observation, it is proper to perform an exploratory opera- tion. DISEASES AND INJURIES OF THE SPINAL CORD. Hydrorachis or Bifid Spine. Hydrorachis is a congenital protrusion of the membranes of the spinal cord and sometimes of a portion of the cord itself or of the spinal nerves through an opening in the posterior part of the vertebral column. The DISE As Es AND IN J U RIES OF THE SPIN AL CO R D. 199 deficiency of the bony wall is due to imperfect development of the laminae and spinous process of one or more vertebrae; hence, the name of bifid spine. The protruded membranes are distended by cerebral spinal fluid forming an elastic and sometimes fluctuating tumor. A more proper name would be spinal meningocele. Those protrusions containing por- tions of the cord would then be called myeloceles. The deformity occurs most frequently in the lumbo-sacral region.

The tumor varies in size and in tenseness with the position of the child, and in occasional instances has no cutaneous investment whatever, being a mere sac of thin spinal membranes. It is apt to become more tense or larger when the child cries. The fluid can sometimes be pressed back into the spinal canal so that the edges of the fissure in the bones can be distinctly felt. Hydrocephalus and other deformities are often found in the same infant. Paralysis is not uncommon. Death generally occurs from meningitis, convulsions, or paralysis, or from rupture or ulceration of the sac. Support and moderate pressure by means of elastic bandages or cup- shaped pads afford proper palliative treatment. When the growth is rapidly increasing a portion of the fluid may be withdrawn by an aspira- tion-needle, introduced at the side of the median line where nerves are not likely to be situated. If the orifice of communication with the spinal canal is small, injections of tincture of iodine, ligation with the elastic ligature, or excision may be practised. All tumors over the spine in children are not cases of bifid spine; but the possibility of this condition 200 DISE ASES AND IN J U RIES OF NER V OU S CENTRES. existing should always be in the surgeon’s mind before undertaking Operation. INFLAMMATION OF THE SPINAL CORD FROM SURGICAL CAUSEs. VARIETIES.—The inflammatory process may be located in the mem- branes (spinal meningitis), or in the substance of the cord (myelitis). It frequently happens that meningitis and myelitis are associated. PATHOLOGY..—In traumatic cases the inflammation is usually local, but the pathological changes may gradually spread along the spinal marrow. Injection of vessels, effusion of serum, exudation of lymph, formation of pus, and softening of nervous structure are the results found at the after- death examination. Sclerosis may occur in chronic cases. CAUSES.—Intraspinal inflammations of surgical causation arise from contusions or lacerations, and other direct wounds of the contents of the vertebral canal; and from fracture, caries, and necrosis of the vertebrae. SYMPTOMS.–There are certain differences in the symptomatology of meningitis and myelitis which will be discussed in speaking of diagnosis. Here the symptoms of spinal inflammation in general will be described. As the cause is local the inflammation is limited ; hence, chills, high fever, and great constitutional disturbance are unusual. Pain in the spinal region, aggravated by motion or pressure, and often reflected along the nerve trunks, is exhibited. Burning and tingling sensations and a feeling of insects creeping over the body; local hyperaesthesia of the surface; more frequently cutaneous anaesthesia; delay in perceiving the contact of points; and a sense of constriction about the body marking the upper limit of the disease are common symptoms of inflammation of the cord and its coverings. Muscular jerkings and spasms, and Subsequently permanent muscular contractions, affecting the muscles supplied from the diseased region, are especially associated with meningitis. Motor paralysis below the seat of lesion is usually present, being much more permanent and complete in myelitis. The palsy, as a rule, involves both sides, and is due to division, com- pression, or disorganization of the nerve fibres of the cord. If paraplegia occurs immediately after the receipt of injury, it indicates that the fibres are divided, or have been compressed by displaced bone or extravasated blood. A slowly determined paralysis suggests inflammatory pressure or disorganization. Injury of one side of the spinal marrow would give rise to unilateral palsy on the same side. It is possible in lesions of the cervico- dorsal area of the cord to have motor paralysis of the arms and not of the legs. As the cord terminates at the level of the second lumbar ver- tebra, injuries below this point are accompanied by no paralysis, or by a slight and temporary form only which depends upon lesions of the loose bundle of nerves called the horsetail. The Small diameter of the cord immediately above its lower end and the envelopment of this termination in the nerve roots going down the vertebral canal serve to prevent severe involvement of the cord, even at a somewhat higher level than the lumbar vertebra mentioned. The seat of the cord lesion can often be determined by the limitation of the motor or sensory paralysis. The muscles and regions supplied by branches given off from the spinal marrow below the injury are usually the only ones that lose their innervation. On account of the downward distribution of the nerves as they leave the cord, the lesion is generally IN FL. A. M M AT I O N OF T H E S P J N A L CO R D . 201 somewhat higher than the horizontal line marking the upper limit of the palsy. An exception to this may occur when the terminal nerve filaments are distributed upward. This occurs especially in the skin.” The paralyzed parts are exceedingly liable to severe bedsores. These are due to the impaired innervation and circulation and to the unrecog- nized irritations which the insensible and immovable parts receive. The local temperature of the palsied limbs is often high. Atrophy soon occurs. Bedsores and atrophic changes are more marked the longer the patient survives. Hence, in injuries low down in the cord these nutritional changes are exceedingly conspicuous. Retention of urine occurs nearly always. When the paralyzed blad- der has become fully distended, there is a dribbling overflow, which is an indication for an immediate catheterization, lest rupture of the bladder or other harm result. After a few days’ incontinence of urine relaxation of the sphincter supervenes. The bladder is thus kept nearly empty. At the same time the urine exhibits chemical changes, becoming alkaline, turbid, ammoniacal and filled with mucus and phosphates. Inflammation of the bladder is usually found at this period, due either to the distention and catheterization, or the alkaline urine, or perhaps to both. Other changes, such as the presence of sugar, are occasionally witnessed. Priapism, either spontaneously exhibited or following catheterization and handling of the genitals, occurs in many instances where motor palsy is a symptom. It has no connection with sexual feelings, and only exists when loss of motion is present. Incontinence of feces is seen when the sphincter is paralyzed by injury to the lowest region of the cord. If the damage is effected higher up, constipation is the condition exhibited. This may subsequently be followed by looseness of the bowels. Dyspnoea and hurried respiration result when the spinal inflammation is located in the upper dorsal and cervical regions because of paralysis of the intercostal and serrated muscles. If the injury disorganizes the cord above the origin of the phrenic nerve, or if inflammatory destruction ascends thus far (to the third or fourth cervical vertebra), death occurs instantly from paralysis of the diaphragm. Difficulty of respiration is experienced in intraspinal troubles in the lower dorsal region ; first, because there is paralysis of the abdominal muscles which aid expiration, and also because the loss of muscular tonicity here allows tympanitic dis- tention of the intestines to occur and interfere with the descent of the diaphragm. When the sympathetic cardiac nerves are interfered with by lesions in the cervico-dorsal region, the pneumogastric nerve can then exert its in- hibitory function unrestrained, and the heart's action is slowed. Other- wise the pulse is influenced merely by the general state of the patient. There are many other symptoms of intraspinal inflammation which depend upon the location of the lesion and the nervous centre consequently involved. From these the location of spinal lesions is established with considerable certainty. It must be remembered, however, that in some cases brain injury has been associated with the spinal hurt. It is occa- sionally difficult to differentiate the spinal from the cerebral symptoms. * See Spinal Localization in its Practical Relations. Therapeutic Gazette, May and June, 1889, by Dr. Charles K. Mills. 202 DISE ASES AND IN J U RIES OF NERV OU S CENTREs. Unconsciousness, when present, renders the diagnosis of cerebral involve- ment clear. DIAGNOSIS.–Memingitis and myelitis are often combined, but the pre- dominant affection can, at times, be diagnosticated by the character of the symptoms. In meningitis there is more pain on motion, more cutaneous hyperasthesia, more twitching and permanent contraction of muscles, less impairment of motility, less involvement of the bladder and rectum. Effu- Sion occurring in meningitis may cause paraplegia by pressure on the cord, but the paralysis is not as complete as in myelitis, and varies in its degree. In myelitis the loss of power occurs earlier and is more marked, electric contractility and reflex movements are soon impaired, and the sense of constriction about the trunk is conspicuous. Priapism, urinary complica- tions, bedsores, and nutritive changes are usual. PROGNOSIS.—The higher the seat of inflammation the graver the prog- nosis as to prolongation of life, because more of the vital functions are impaired. Myelitis is a much more serious affection than meningitis, and is seldom followed by restoration of the paralyzed limbs. If the injury is low down in the spine, or if, when higher, it implicates a limited area of the cord, recovery of a fair amount of health occasionally takes place. Contractures and paralysis, however, usually remain. Sensation is usually regained sooner than motion. TREATMENT.-Intraspinal inflammation requires a line of treatment similar to that recommended in encephalitis. Rest, preferably in the prone position, the ice-bag, leeches or wet cups locally ; hydragogues, iodide of potassium (gr. X to 3.j), or mercury to slight ptyalism, and fluid extract of ergot (fºss to fºj), given internally several times daily, are the proper measures in acute cases. Morphia and bromide of potassium may be employed to relieve pain and induce functional rest. Atropia is an appro- priate remedy in meningeal congestion. When the condition is subacute, blisters or the actual cautery may be applied to the spine and the induced current to the paralytic muscles with advantage. Hammond says that in acute partial myelitis he has got benefit from large doses of ergot, and the actual cautery applied along the sides of the spinous processes. Strychnia is to be avoided in spinal meningitis. The paralyzed muscles of chronic myelitis should be treated by means of electricity, massage, the hot and cold douche, and subcutaneous injections of strychnia, in the endeavor to prevent atrophy and restore power. Syphilitic meningitis and myelitis especially call for mercury and iodide of potassium in active doses. Suspension by the shoulders and head from a tripod, so as to extend the spinal column by the weight of the lower limbs, has been advocated in some forms of chronic disease of the cord. When retention of urine exists, the catheter must be passed three times daily. The cystitis that arises later and is accompanied by phosphatic urine, is alleviated at times by carefully washing out the bladder with mitric acid and water (mºv to fj). Even if incontinence has occurred, it is well to pass the catheter once every three or four days to empty any decomposing residual urine. An attempt at preventing bedsores should be made by seeing that there are no folds in the sheets, by bathing the prominent points of back and limbs with alcohol, and by keeping them free from contact with the urine and feces. It is well to place the patient as soon as possible upon an air or water bed. A good water bed can be improvised by partly filling a long tank or tub with water, and nailing a rubber blanket over the top, so that it will rest upon the surface of the water. N E U R ITIS, OR IN FLA M M ATION OF NER V E S. 203 If a clear diagnosis of abscess within the spinal canal was made, it would be justifiable to trephine the vertebra, or to saw away the laminae in an effort to evacuate the pus. In localized inflammation due to frac- ture or other cause, trephining followed by separation of the adherent membranes and cord might possibly give relief to the symptoms. Explo- ratory operations here, as in brain diseases, are justifiable." WOUNDS OF THE SPINAL CORD. Wounds of the spinal marrow may be produced by gunshot injuries, by fractures of the spinal column with displacement, or by pointed instru- ments thrust between the vertebrae. The symptoms will be those pre- viously detailed as occurring in injuries and inflammation of the cord. They will vary with the locality of the wound. Such wounds, involving a limited portion of the diameter of the cord will be followed by a limited paralysis, corresponding with the fibres divided. t The treatment of wounds of the cord is such as is detailed for arresting and treating intraspinal inflammation. When fragments of the vertebra are driven in upon the cord instrumental elevation is justifiable, but the diagnosis of such compression is often difficult. Exploratory operation may then be demanded. s CONCUSSION OR CONTUSION, AND LACERATION OF THE CORD. Shocks, whether direct or indirect, to the spinal column are not trans- mitted to the cord as readily as similar blows are to the brain, because the cord hangs loosely in the canal, and is surrounded by the spinal fluid. I believe that cases denominated concussion of the spine are really in- stances of contusion or laceration of the cord or its membranes or of extravasation from rupture of the spinal veins. The progressive spinal symptoms described by Erichsen as occurring after the jarring of railway accidents, and attributed by him to so-called spinal concussion, are, in my opinion, probably due to slight contusion or laceration of the contents of the spinal canal. Contusion and similar injuries of the cord require treatment adapted to preventing and allaying inflammation of this nervous centre. NEURITIS, OR INFLAMMATION OF NERVEs. CAUSES.–Neuritis, which may be acute or chronic, arises from expo- sure to cold and wet, wounds, strains causing laceration of the nerves, rheumatism, gout, and syphilis. Acute neuritis is particularly liable to follow laceration of nerve-trunks; and yet nerves may often be exposed to considerable traumatic irritation without becoming inflamed. PATHOLOGY..—An inflamed nerve shows changes in the neurilemma and nerve-fibres. Hyperaemia, increased connective tissue, serum, lymph, and pus are the inflammatory changes associated with the former; while granular and fatty changes followed by softening and atrophy occur in the latter. In acute neuritis the nerve-trunk is swollen from the depo- sition of inflammatory fluids, and pus may be found within the sheath. * See Surgery of the Spinal Cord, by Dr. J. William White. Annals of Surgery, July, 1889. 204 I) IS E A S E S A N ID IN J U R IES OF N E R W E S. If the nerve is superficial a hardened cord is often felt beneath the skin. In chronic inflammation an increase of the connective tissue, leading to Sclerosis and consequent nerve atrophy, is the usual pathological change. SYMPTOMS.–Inflammation of nerves causes disturbance of physiological function, hence the symptoms vary as the nerve-trunk is motor, sensory, or mixed. Inflammation of nerves of special sense, such as the optic and auditory, is not discussed here, but belongs to the domains of ophthal- mology and otology. The first effect of inflammation is to increase the irritability of nerves, but, as it continues, a diminution of nervous excitability is induced. Hence, in motor neuritis, twitching and spasm of the muscles occur at the time of invasion, and are followed by paresis or complete loss of power if the inflammation is not speedily arrested. Sensory neuritis exhibits mainly pain and hyperaesthesia followed by analgesia and anaesthesia. When the inflammatory process resides in a mixed nerve, as it generally does in cases met by surgeons, these classes of symptoms are combined. Reflex influences may at times, however, cause the appearance of symp- toms of a motor character, even when a purely sensory nerve is inflamed. For example, neuritis of the trifacial will be accompanied by twitching of some of the muscles of the face. The term causalgia is applied to the peculiar burning pain of some nerve inflammations. Inflammation as found in neuritis of the sciatic, radial, and similar nerves, then, is exhibited by pain, of a remittent, but not intermittent, character, increased by pressure, often worse at night, and especially severe when due to traumatism. There will perhaps be reflex symptoms such as pain in other parts of the body. The painful sensations are felt in the peripheral distribution of the nerve, and may exist even when the skin has become anaesthetic. Reflex excitability and electric contractility are soon diminished. The local temperature of the parts supplied is increased, and the skin over the course of the trunk is red, and sometimes the seat of a bullous eruption. A hard, painful, cord-like swelling is felt along the course of the trunk, if it is a superficiul nerve that is involved. Clonic spasms, loss of power, hyperaesthesia, anaesthesia, and atrophic changes are supplementary symptoms. Fever and other constitutional symptoms occur, varying in intensity with the acuteness of the neuritis. Chronic neuritis causes much less pain, but the other functional dis- turbances are those already mentioned. Neuritis may spread along the trunk to nerves nearer the nervous cen- tres. This is called ascending neuritis. In a similar way changes may occur above and spread downward, constituting descending neuritis. Neu- ritis may be followed by ulceration, deformity of joints, and other second- ary pathological conditions. DIAGNOSIS.–Neuritis is distinguished from neuralgia by the continuous pain, which may remit but does not intermit; and by the fact that the pain is usually less severe than the paroxysmal pain of neuralgia. In neuralgia, moreover, there is not the local elevation of temperature, the muscular spasm, the paralysis of motion or sensation that have been mentioned as symptomatic of neuritis. TREATMENT.-Acute neuritis demands absolute rest and elevation of the part, ice-bags locally, and, perhaps, local abstraction of blood, Deep subcutaneous injections of morphia (grain to £) with atropia (grain ºw) over the painful nerve, and the application of the primary galvanic I N J U R.I.ES OF N E R W E S. 205 current has been useful. The general disturbance will probably necessi- tate at the same time the use of diaphoretics and laxatives. Chronic inflammation of nerves is to be treated by blisters, electricity, the actual cautery and increasing doses of iodide of potassium, Hypo- dermic injections of chloroform, solutions of osmic acid or of cocaine may at times be serviceable. Nerve-stretching is a recently introduced operation for chronic pain of nerve-trunks. The nerve is exposed by an incision and stretched by being forcibly pulled out of its bed by the surgeon's finger or a hook. If the inflammation is due to rheumatism, alkalies and Salicylate of sodium are indicated; if to gout, colchicum ; if to syphilitic causes, mercury and iodide of potassium. The actual cautery has been used also in acute neuritis with alleged benefit. The atrophied muscles are to be subjected to massage, electricity, douches, and hypodermic injections of Strychnia (grain ºw). Tomics and similar remedies will often be of value in chronic neuritis. INJURIES OF NERVES. Nerves are liable to be bruised and lacerated as occurs when the ulnar is compressed against the internal condyle, and when the circumflex is torn in dislocation of the head of the humerus. They may be punctured, incised, completely divided, or have a portion excised. SYMPTOMS.–The symptoms in such injuries, whether open or subcuta- neous, vary with the degree of damage done to the nerve-fibrils. Slight contusions cause pain at the point of injury and tingling or numbness along the peripheral branches. Other wounds give rise to pain followed by paresis or paralysis. Sometimes pain is absent. A foreign body impacted in a nerve is apt to cause spasmodic action of the muscles in addition to the pain and other symptoms. Subsequent to the receipt of injury the symptoms of neuritis occur. Neuralgia is often developed as a sequel to nerve wound. This is espe- cially the case in hysterical subjects. When the nerve is compressed or dragged upon by the cicatrix of the wound in the other tissues, nutritive changes take place in the parts deprived of innervation. These consist in atrophy and contracture of muscles; alterations in the nails; and changes in the skin, which may become shining and swollen or eczematous; low- ered local temperature; loss of hair; and subacute arthritis. The ends of a divided nerve retract, become bulbous from the deposi- tion of lymph, and, after the lapse of several weeks or months, are re-united by the development of nerve tissue, thus having their function restored. This will at times happen even when a considerable piece of nerve has been cut out. Hence, when it is desirable, after operation for neuralgia that union should not occur it is necessary to excise a long piece of nerve trunk or turn back the distal end. During the period required for restoration of function the neighboring nerves seen at times to fulfil, in part at least, the duties of the injured trunk in much the same manner as the collateral circulation is carried on when an artery is obstructed. TREATMENT.-Subcutaneous nerve injuries need only such treatment as will prevent or allay the resulting neuritis. Hypodermic injections of morphia and atropia, cold, or perhaps hot applications, and galvanism 206 D IS E A S E S A N D IN J U R IES OF N E R W E S. locally, with quinine or other appropriate remedies internally, are judi- cious measures. Other local remedies of value are belladonna extract, menthol, chloroform and aconitia, used as lotions or ointment, blisters, leeches, and the actual cautery. In open wounds, where there is a tendency to considerable separation, union can very properly be hastened by suturing the extremities together with catgut. No special manner of introducing such stitches is required, if only approximation is accurately made. The after-treatment is that calculated to prevent neuritis. If a wound, in which there was a large nerve divided has healed and permanent paral- ysis remains, it may be justifiable to expose the nerve, cut off the bulbous or atrophied extremities, and apply sutures. Considerable success has been obtained in restoring motion to limbs, the subject of traumatic paralysis from accidental nerve section. Pieces of nerve tissue from the rabbit may be sutured in the gaps left by destruction or excision of nerve trunks. Neuralgia, due to cicatricial pressure, is treated by excising the innod- ular tissue, and thus getting rid of the scar and the pinched nerve. Other neuralgias after nerve injuries require the treatment detailed in the article on Neuralgia. Newralgia. DEFINITION.—The term neuralgia was introduced into medical language to signify pain referred to the course of a nerve without apparent lesion. The pain was said to be functional. Pathological observation, however, has shown that many instances of pain, formerly called neuralgia, are really due to inflammation or compression of the nerves, or to other defi- nite organic changes. Neuralgia should, therefore, be restricted to nerve pain in which no lesion is evident, though more accurate pathological knowledge will doubtless still further lessen the cases to which the name is appropriate. Neuralgia then may be defined as pain, usually paroxysmal, situated not in the brain or cord but in the nerves themselves, and due to no dis- coverable organic lesion. CAUSES.—The chief constitutional cause of neuralgia is debility. When the powers of life wane from old age, or when anaemia exists in young or old, there neuralgia is liable to appear as an unwelcome visitor. Malaria is a very frequent cause of neuralgia, especially of the trifacial nerve. Hysteria, exposure to wet and cold, reflex irritation from uterine disease, syphilis, rheumatism, and gout are considered factors in the etiology of neuralgia. Some of these probably cause nerve-pain by inducing neuritis and not true neuralgia. The same fallacy is likely to underlie cases of neuralgia attributed to diseased teeth, necrosis of bone, and periostitis. Compression of nerves by tumors and periostial thickening gives rise to neuralgic pain. SYMPTOMS.—The most frequent situations for neuralgia are the terminal branches of the three divisions of the trifacial nerve, the sciatic nerve, and the intercostal nerves. Neuralgia may be seated in a number of small, nervous twigs, distributed to an organ or surface of considerable size; thus, we have neuralgia of the breast, of the testicle, and of joints. The pain of typical neuralgia is sudden and paroxysmal. It occurs as a tearing, darting shock or pang followed by an interval of more or less complete absence of pain. In many instances there is a dull, aching pain N E U R A L G. I. A. 207 continuously, to which are added at irregular intervals the painful ex- acerbations. Muscular exertion generally, and pressure sometimes, though not usually, aggravate the pain. Neuralgia shows quite a tendency to be unilateral, and often there is exhibited marked cutaneous hyperaesthesia. Points of tenderness on pressure can, as a rule, be found along the course of the nerve. These are situated where the nerve passes through a bony foramen, pierces the deep fascia, or comes near the surface of the body. Occasionally tenderness is exhibited over the part of the spinal cord from which the nerve takes its origin. Local muscular spasm is found associated with some neuralgias, as are at times a hot, red, swollen skin and increased secretion of the neighboring lachrymal or salivary glands. The peculiar vesicular eruption called herpes zoster is developed over the line of a neuralgic nerve. Patients who have once suffered with neuralgia are liable to similar ex- perience at every exposure to the exciting cause. The location of the neuralgia may vary with each attack. Indeed, the pain is very liable to change from one nerve to another. Neuralgia, particularly of the trifacial nerve, is often very intractable, but it is not a disease dangerous to life. DIAGNOSIS.–It is easy to differentiate a typical neuralgia from marked organic disease. There are no alterations in shape or volume, no signs of inflammation, no fever, but paroxysmal pain, cutaneous hyperaesthesia, and a history of debility, malaria, or hysteria. Firm pressure frequently relieves neuralgic pain, if it is continued until the hyperaesthetic skin has become accustomed to the contact of the hand. The tendency of neuralgia to be transferred from one nerve to another is a valuable point in diag- nosis. In many cases, however, neuralgia can only be presumed to exist, because the pain cannot be attributed to any other affection. Muscular and fascial pains due to rheumatism or syphilis are often mistaken for neuralgia. TREATMENT.-As the constitutional condition underlying neuralgia is usually either debility or malaria, quinine and its congeners are the most useful internal remedies that we have. Quinine should be given in full doses even when no malarial history can be obtained. Twenty to thirty grains in the twenty-four hours may be curative when less doses have accomplished nothing. If this drug fails, recourse should be had to arsenic. The solution of arsenite of potassium should be given in doses of five to ten minims three times daily after eating, and be gradually in- creased. The same preparation may be employed hypodermically in about half this amount, diluted with water and also increased by degrees. Iron, strychnia, and cod-liver oil in large doses frequently repeated, gal- Vanism, good nutritious diet, fresh air, sea bathing, change of scene and climate are valuable agents in combating the tendency to neuralgia. In hysterical subjects, valerian, bromide of potassium, and assafoetida may be available; in rheumatic cases, alkalies; in those of gouty diathesis, col- chicum ; and in syphilitics, iodide of potassium or mercury. Ergot and phosphorus have been recommended by high authority. - Uterine or other affections giving rise to neuralgia by reflex influence should be remedied by appropriate measures. To relieve an attack of neuralgia, when present, morphia, atropia, chloral, hyoscyamus, bromide of potassium, alcohol and the inhalation of anaesthetics have a positive value. The use of such remedies is to be deprecated and their repetition avoided as far as practicable, because of the early necessity of increasing the dose and the liability of inducing in- 208 DIS E A SES A N D IN J U R IES OF N E R W E S. temperance in their employment. Neuralgic patients, for this reason, should not be informed of the name of the remedy administered. Aconitia may be given in doses of gr. 3 #5 and gradually and very cautiously in- creased. The benumbing effect of this powerful drug on the peripheral nerve is well known. Menthol locally gives at times relief. The local treatment of neuralgia deserves attention. Any suspected local cause, such as diseased teeth or cicatricial pressure, should be re- moved. In many of these instances, however, the pain is probably due to a neuritis and, hence, is not true neuralgia. Hypodermic injection of morphia (gr. #-gr. 4) into the nerve trunk or in its in mediate neighbor- hood is a potent remedy and may not only palliate, but by repetition even cure. The needle of the syringe should be thrust deeply into the tissues and, if possible, into the nerve. Atropia (gr. Gº-gr. jº) alone or com- bined with morphia, ether (m, x-xxx), chloroform, or bromide of ethyl, or solution of osmic acid may be employed in a similar manner. These and other sedatives may also be used in the form of liniments and oint- ments. Aconitia (gr. v to 3.j of ointment), veratria (gr. xx to 3.j of oint- ment), and menthol are often very efficacious local applications. Heat and cold vary in different cases as to the amount of relief they afford. The primary galvanic current is at times useful. Blisters, strong water of ammonia. the actual cautery, and similar counter-irritants have a positive value in some instances. Acupuncture and galvano-puncture have been recommended. Nerve-stretching, nerve-section (neurotomy), and nerve-excision (neu- rectomy) are proper surgical expedients only when the neuralgia is very severe and intractable. Nerve-stretching is performed by making an incision over the trunk, iso- lating it and lifting it out of its bed by a hook or the fingers. Strong traction is then made upon it in the direction of the peripheral branches, that is, away from the cerebro-spinal end, a considerable increase in the length of the loop is apparent. If the operation is done without ether, or if only local anaesthesia has been employed, the traction is to be con- tinued until numbness of the periphery is experienced by the patient. The operation is only painful on account of the cutaneous or muscular incisions. The numbness and paresis of the parts to which the nerve is distributed soon pass away. Nerve-stretching has accomplished many cures of neuralgia. It has also been done for spasm of muscles. Strong compression of a nerve against a bone or by a screw clamp may relieve neuralgia by crushing the nerve fibrils. Simple section of a nerve is of little value in obstinate neuralgia, because union soon takes place; hence, excision of one or two inches is much more successful. The neurectomy or excision should remove a por- tion of nerve as far as possible behind the seat of pain, for this gives the best chance of getting above the seat of pathological changes. The distal end of the divided nerve may be turned back, or a portion of muscle may be interposed between the ends to prevent union and recurrence of pain. If the neuralgia depends upon peripheral nerve change, these operations are usually permanently beneficial; but if the pain arises from altera- tions in the nerve centres, nerve-stretching and neurectomy give only tem- porary comfort. The absence of pain for several months, however, is often a great boom. The palsy after neurectomy is generally permanent. It has been suggested to cut out the cortical brain centre, from which the painful nerve has its origin, if this can be determined by central locali- zation. T E.T A. N. U. S. 209 The three divisions of the trifacial are often excised. The supraorbital nerve is reached by an incision along the supraorbital arch, after which the nerve should be cut off as far back in the orbit as possible. If the nerve comes through a distinct foramen, this foramen may be converted into a groove by cutting out the edge of the bone with a chisel and then a hook can be passed above the globe of the eye so as to enable the surgeon to drag the nerve forward. The infraorbital may be reached in a similar manner; by trephining both the anterior and posterior wall of the antrum this nerve may be cut off close to the exit of the main trunk from the round foramen in the sphenoid bone. It can be torn off nearly this far back by swiftly cutting away with a chisel the edge of the orbit and seizing it with strong forceps in the floor of the orbit. The inferior dental is best reached by trephining the ramus of the lower jaw and exposing the nerve in its canal. Another method is to lay bare the mental foramen, and by means of the disk of the surgical engine, or with chisels, to remove the roof of the inferior dental canal as far back as is deemed necessary. It must be recollected that the alveolar process in old persons, in whom these operations are especially demanded, is generally absorbed, and the canal is relatively further from the lower border of the bone than in young adults. TETANUs. DEFINITION.—Tetanus is a disease characterized by persistent and painful muscular contraction due to abnormal excitability of the medulla oblongata and spinal cord, which is probably dependent upon inflamma- tion of the central gray matter of these organs. PATHoLOGY..—The weight of evidence was until recently in favor of considering tetanus a disease of the nervous system, and not a blood affection, due to the introduction of some poisonous agent into the circu- lation. The pathological condition was thought to be probably inflamma- tion of the gray matter of the medulla oblongata and spinal cord. Hyperaemia, extravasation, exudations, and softening have been detected, especially in the posterior horns of gray matter and in their immediate vicinity. When the disease is caused by injuries to the lower extremities these changes are said to be found in the lumbar enlargement; when the Wound is situated upon an upper extremity, in the cervical enlargement of the cord. Sometimes the nerves in the neighborhood of the wound are found inflamed, but this peripheral neuritis does not seem to be an essen- tial lesion. The most recent investigations seem to indicate the probability that tetanus is due to a microörganism, which would explain its occasional contagiousness and many points in its clinical history. CAUSES.–Traumatism is the usual exciting cause of tetanus, but it may, especially in hot climates, occur idiopathically. The latter is some- times termed rheumatic tetanus. Occasionally tetanus seems to be endemic. A sudden change from a high to a low temperature, with dampness, is liable, especially in military practice, to be followed by cases of traumatic tetanus. Traumatic tetanus often occurs in vigorous patients who have Sustained injuries, but it is probably more frequent in those of lowered nervous tone from shock, hemorrhage, deprivation of food, and want of fresh air. It is said to be more common in the negro than in the white race. There is no direct relation between the severity of the injury and the tetanic symptoms. The slightest bruise, puncture or surgical opera- & 14 - r 210 DISE AS ES AND IN J U RIES OF NER V OU S CENTRES. tion may be followed by the most violent form of tetanus. Burns and lacerations are more apt to give rise to this complication than incised wounds. It is doubtful whether wounds of the feet and hands are especially prone to cause tetanus, though some authorities believe that such is the case. Tetanus in newly-born infants has been ascribed to the ligation of the umbilical cord, and to pressure upon the cranial bones during birth. ^ SYMPTOMS.–The symptoms of idiopathic tetanus are identical with, though usually less severe than, those of the traumatic form. The treat- ment is the same in both varieties, except that in one attention to the wound is required. * The time of appearance of traumatic tetanus is usually from five to ten days after the receipt of the injury; though the initiatory symptoms may be exhibited in a few hours, or delayed until several weeks have elapsed. The early cases are apt to be more acute in their progress, violent in symp- toms, and fatal in prognosis. Digestive disorders, or general and indefi- nite uneasiness may perhaps be observed, or possibly the wound may become dry and unhealthy before the characteristics of tetanus are devel- oped. In many instances, however, nothing unusual attracts attention until stiffness and pain in the muscles of mastication or pain in the epi- gastrium, proclaim the advent of this serious complication. It is rarely that the muscular spasm shows itself primarily in the wounded limb. Pain in the epigastrium from spasm of the diaphragm, or painful rigidity of the muscles that close the mouth and of the back of the neck, is the usual initiatory symptom. The muscles thus primarily affected are those supplied by the motor branch of the trifacial nerve, the facial, and the spinal accessory nerves. The muscular spasm is continuous, or tonic, though there are occasional paroxysms of increased contraction. The contraction is exceedingly powerful. The voluntary muscles, except those of the hands, feet, eyeball, and tongue, generally become rigid soon after the incipiency of the disease. The epigastric pain is attributed to spasm of the diaphragm, and it is believed by some that death may occur from cardiac spasm. These are possible examples of the tetanic spasm occur- ring in muscles of involuntary innervation. The pain accompanying the muscular spasm is severe, resembles that of ordinary cramps, and shows exacerbations at the times when the rigidity increases. When the poste- rior muscles are more especially affected the patient's head and legs are bent backward, until he assumes such an arched position that, if placed in the supine posture, only his occiput and heels would touch the bed. This condition is called opisthotonos. The term emprosthotomos is em- ployed to designate a similar flexion forward, and pleurothotonus to denote lateral deflection. Opisthotonos more or less marked is the common pos- ture; the others are very rare. The inability to open the mouth gives tetanus the popular name of locked-jaw. The medical term for the spasm of the jaw muscles is trismus. The power of tetanic spasm must be seen to be appreciated. Muscles may, at times, be ruptured by the violent contraction, and the patient becomes unconscious from the unendurable alſl, p The patient suffers from difficulty in swallowing, dyspnoea, and sleep- lessness. There is sometimes aphonia, and occasionally the tongue is bitten by a sudden paroxysmal spasm of the temporal muscle. On ac- count of this danger the surgeon should avoid requesting the protrusion of the tongue. Viscid saliva may collect in the mouth and annoy the patient. The mind is perfectly clear, but the facial expression is charac- T ET A N US. 211 feristic. The sardonic grin of tetanus, as it is called, consists in retrac- tion and elevation of the corners of the mouth, closed teeth, transverse furrowing of the forehead, dilatation of the nostrils, and a fixed, anxious expression of the eyes. Constipation and retention of urine are usually present. Reflex excitability is so great that the noise of a suddenly closed door, a draft of air, the touch of the surgeon's hand, or a flash of light may induce an exacerbation of spasm. Respiration is embarrassed and quick- ened, and the pulse feeble. In the early stage there is little fever, but toward the termination of the disease high temperature and profuse sweating are not infrequent. Instances of very high temperature have been observed, and cases have been reported in which the bodily heat rose even after death. The exhaustion arising from the continuous muscular action is very great, and is often the cause of death, before which relaxation may take place. The fatal issue may occur from spasm of the respiratory muscles, and possibly from spasm of the heart. Fatal cases terminate usually in from three to five days. DIAGNOSIS.—Local rigidity of the masticatory muscles, due to cold, or diseased teeth, is distinguished from tetanus by the absence of pain, the non-occurrence of paroxysmal increase of spasm, the absence of hardness of the abdominal muscles and of other tetanic symptoms, and, finally, by its curability, particularly after removing the cause. Spinal meningitis has a different history, gives rise to rigidity of the extremities and neck, rather than to trismus, and is followed by paralysis. - In hydrophobia we see a convulsed and restless face instead of the knit brow and grinning mouth of tetanus. Moreover, there is delirium, and the spasms are intermittent or clonic. The profuse secretion of saliva and the convulsive attacks following attempts at deglutition are not a part of the clinical history of tetanus. Hysteria assumes the characteristics of tetanus. It may be differentiated by considering the sex and character of the patient, and by observing the absence of pain, the intermission or irregularity of the tonic rigidity, and the transient nature of the spasm when the application of the actual cau- tery is suggested. Strychnia poisoning, particularly when produced by the repeated admin- istration of Small toxic doses, greatly resembles tetanus. Here, however, spasm occurs in the limbs sooner than in the jaw, epigastric pain is absent, and opisthotonos arises at an earlier time than in tetanus. There is, moreover, no history of traumatism, which, however, is absent also in idiopathic tetanus. In most cases of strychnia poisoning, death or recovery occurs within a short period ; and there can usually be elicited a suspicious history of suicide or homicide. PROGNOSIS.—Tetanus arising within nine days of the time of injury is almost invariably fatal. Recoveries from tetanus, which are rare, are usually instances of the disease that have arisen nine days or more after the receipt of injury, and that have shown symptoms of but moderate violence. If the patient survives the fourteenth day of tetanus, recovery may be expected. High temperature is an unfavorable symptom. TREATMENT-Although the death-rate of tetanus is very high, treat- ment that lessens peripheral irritation and diminishes spinal excitability always palliates suffering, and may at times be followed by cure. The patient should be kept in a quiet, darkened room, free from draughts of air, and should be supplied with concentrated liquid food because of the ex- haustive character of the disease. Food can be introduced by a flexible 212 DISE A SES AND IN J U RIES OF NER V OU S C E N T RES. tube passed between the cheek and the teeth, so that the liquid may enter the mouth behind the molars; or by a similar tube passed into the pharynx through the nostril. Usually, however, there are crevices between the teeth which admit the entrance of milk or soup. Such alimentation is preferable to rectal feeding, though the introduction of partially digested liquid food into the rectum may be valuable. Freedom from noise may be obtained by putting cotton in the patient's ears. Iron, quinine, and stimulants may be desirable to sustain the failing powers. Laxatives or enemas may be required. Active purgation is in- jurious. The best remedy to control reflex excitability is, in my opinion, hydrate of chloral, which should be given in ten or twenty grain doses every one, two, or three hours. These doses may be increased if the patient does not become quiet and sleep. I have had good results follow this treatment, but it must be admitted that the cases were not of the most violent type. Extract of physostigma (gr. j. every two hours and increased), or its active principle, eserine, hyoscine, urethan, etc., are worthy of consideration if chloral in large doses does not seem satisfactory. These remedies should be given early, and in doses as large as experience shows can be tolerated before resorting to other drugs. Chloral has been successfully used by enema, and eserine is very readily administered by hypodermic injection. Opium has some reputation in the treatment of tetanus, but it is probably better to use it as an adjunct to the chloral, to relieve pain. Bromide of potassium, cannabis indica, conium and similar substances, and the inhalation of anaesthetics have been advocated. Hammond strongly recommends, in addition to internal treatment, the application of the ice-bag to the spine. Local measures should be adopted to prevent peripheral irritation. The wound should be freed from foreign bodies impacted in it, made aseptic, and dressed with 'antiseptic gauze. Stretching, incision, and excision of the nerve trunks have been employed, as has amputation, with varying results. When the nerve supply cannot be definitely fixed it has been proposed to make a deep incision down to the bone and thus divide all the nervous filaments. All these operations are regarded as of doubtful expediency by most authorities, though they are, perhaps, justifiable in such a hopeless condition. As such operations cannot be resorted to until tetanus has arisen, and as the symptoms prob- ably depend upon a microbic cause, I doubt the utility of their perform- ance. Neurectomy is apparently the most judicious procedure if any operation is done. Tracheotomy has been advised to meet the possibility of death by laryngeal spasm. HYDROPHOBIA. DEFINITION.—Hydrophobia is a disease of fatal prognosis, character- ized by sudden spasm of the respiratory muscles upon attempts at deglu- tition and by other nervous phenomena, and which is generally believed to be a blood disease due to inoculation with a specific virus contained in the oral secretions of rabid animals, though there is some evidence sug- gestive of the symptoms being manifestations of central nervous disease, initiated in traumatic cases by the peripheral irritation of the injured nerve branches. CAUSE.-If the generally accepted theory be correct, the cause of hy- drophobia is a peculiar poison contained in the secretions of the mouth of animals affected with rabies. The disease is believed to be generated H Y I) R O PHO BIA . 213 spontaneously only in the canine family, in the cat, and a few other animals; but it can be communicated by inoculation to others, whose oral secretions then become virulent. It has not been proved that it can be communicated from one human being to another. Innoculation with other fluids of affected animals does not produce the disease. It has been sug- gested that bites by female animals in heat are, perhaps, more likely to cause hydrophobia than those of males or females under other circum- stances. Microörganisms have been described as found in the secretions from the mouths of rabid animals, and to these fungi the communicability of the disease has been attributed. Many persons bitten by rabid dogs experience no unusual sequences, possibly because the saliva was absorbed by the clothing through which the injury was inflicted. Another theory of the obscure disease called hydrophobia is that it is a reflex neurosis; in other words, that the wound, for hydrophobic symp- toms are usually consecutive to a wound, causes irritation of the peripheral nerves, which, in turn leads to molecular and vascular changes in the medulla oblongata and pons Varolii. If this theory is true, it follows that hydrophobic symptoms can probably occur after other peripheral irritation than that of bites of rabid animals. In fact they could arise when no injury had been received, provided the necessary changes in the medulla oblongata and pons Varolii were incited. There is some evidence that seems to point in this direction. PATHOLOGY..—Changes, such as congestion, extravasation, softening, and granular degeneration have been found in the medulla oblongata, cord, and brain of patients dying with hydrophobia. These lesions are apt to be conspicuous in the medulla oblongata and its vicinity. They may, however, be secondary, and not the essential morbid changes of the disease. In some instances chronic alterations have been discovered in the nervous centres, which may have been the cause of the susceptibility to hydrophobic symptoms when peripheral irritation was induced. These cases seem to support the second theory of the nature of hydrophobia. SYMPTOMS.–Rabies is first exhibited in dogs by listlessness followed by restlessness, but there is no disposition to bite. Afterward the animal may become excited, as is exhibited by barking in a hoarse tone and snap- ping at the air, biting and licking sticks and stones; or he may show symptoms of melancholy and refuse to eat, drink, or observe his sur- roundings. Paroxysmal excitement, spasm of respiration and deglutition, protruding tongue and constant escape of Saliva from the mouth, paral- ysis of the legs, convulsions and tremors may precede death. Rabies is not more common in summer than in other seasons, nor do mad dogs have the dread of water which is exhibited by men with hydrophobia. Much of the animal's excitement is doubtless in many cases due to his being chased by persons desirous of destroying him. In man the period of incubation is usually, it is said, not longer than Seven months. Cases have been reported when only a few days elapsed, and others are recorded in which no symptoms were shown until years had passed. Many of these cases will not bear searching investigation. The wound made by the teeth of the rabid dog usually heals readily; but may, just before the advent of the general symptoms, become the seat of stinging pain or of inflammation. The initiatory symptoms are physical and mental discomfort, stiffness of the throat and tongue, anxiety and irritability of disposition. Then occur spasms of muscles of deglutition and respiration, especially when 214 DISE ASES AND IN J U RIES OF NERVO US CENTREs. attempts at Swallowing water and other fluids are made. This symptom gives the name to the disease. Solids are swallowed more readily than fluids. Cutaneous and sensory hypergesthesia, wild delirium, convulsed features, hawking and spitting of an abundant viscid fluid, attacks of Suffocation caused by drafts of air and attempts at deglutition, hoarse cough, sleeplessness, maniacal excitement, and at times paralysis, or general tetanoid or epileptoid convulsions complete the distressing picture. The pulse is frequent, the temperature high, and the urine often albu- minous or saccharine. Death occurs from spasm or exhaustion about the third day. It is said that dread of water is not always present, and that this symp- tom may occur in other affections. DIAGNOSIS.–Hydrophobia sometimes much resembles tetanus, and, indeed, a variety of the latter disease has been described as hydrophobic tetanus. The differential diagnosis of tetanus and hydrophobia has been discussed in the preceding article. Hysteria may assume the aspect of hydrophobia, but there is a want of consistency in the symptoms and an absence of high temperature. Moreover, the hydrophobic patient tries to conceal his fears from his friends, while the hysterical one endeavors to call attention to them. Hysterical hydrophobia is developed soon after the injury. TREATMENT.--The preventive measures, to be adopted after an injury has been inflicted by the teeth of a mad dog or other animal is the im- mediate excision of the tissues around the wound, or suction followed by cauterization with strong nitric acid, or better with the red-hot iron. The application of a tight bandage to the limb above the wound until excision or cauterization has been effected is proper. The fears of the patient may be allayed by these precautions, even if the time elapsed has been too considerable to give an opportunity to prevent absorption by such means. I believe the application of nitrate of silver to be perfectly valueless. The animal should never be killed, but kept in confinement that the existence of rabies may be verified or disproved. Bromide of potassium in large doses has been recommended during the period of latency. When the symptoms have appeared, treatment, as a rule, exerts little influence in averting death. Nourishment and perhaps stimulation by the rectum, ice to the spine, perfect quiet and freedom from excitement are indicated. Worara (grain Hº to #) or pilocarpine (grain # to #) given hypodermically, nitrite of amyl or chloroform by inhalation, chloral, morphine and bromide of potassium, hyoscine hydrobromate, and similar remedies may be tried, but must be employed in large doses. Pasteur has shown that dogs and some other animals may be protected from rabies by inoculation with attenuated virus of rabies in much the same way as men are protected from smallpox by vaccination. He has asserted that human beings who have been bitten by rabid animals may be protected from the disease by a similar preventive inoculation. His views have not as yet been accepted by the entire medical world. TRAUMATIC DELIRIUM TREMENs. DEFINITION.—This is a nervous affection characterized by muscular tremor and a peculiar restless delirium, which not infrequently follows the receipt of injuries by those accustomed to alcoholic stimulation. CAUSES.—Some writers under the terms traumatic delirium and nervous T R A U M A. T I C D E L I R. I U M T. R. E. M. E. N. S. 215 delirium describe a condition, frequently very similar to delirium tremens, which is said to occur in patients free from the alcohol habit and to de- pend upon nervous prostration, often associated with shock and hemor- rhage. It is possible that failure to investigate previous habits with judicial acumen has allowed to arise a confusion between delirium de- pendent simply upon traumatism and delirium induced by traumatism in alcohol drinkers. The muttering delirium and muscular twitching that supervene in nervous prostration or asthenia from surgical as from medi- cal causes, and the noisy delirium after injury, that is usually exhibited by quick, rapid, and full pulse and by febrile reaction, are two very different conditions to which the name traumatic delirium may with pro- priety be applied. These forms of mental disturbance—better in my opinion called, in the one case, nervous or asthenic traumatic delirium, and, in the other case, septic or inflammatory traumatic delirium—arise without reference to personal habits. These two conditions are possibly often intermingled with alcoholic traumatic delirium or traumatic delirium tremens, as I here term it. The group of symptoms which I propose describing as traumatic delirium tremens, is found especially, if not exclusively, indeed, in those whose nervous systems have undergone, prior to injury, the deterioration due to absorption of alcohol. I have not been convinced by my experience, which I admit to be somewhat limited, nor by my reading that such a concatenation of symptoms can occur after traumatism in the absolutely abstemious. The amount of drinking requisite to induce the predisposi- tion varies with the individual. The repeated ingestion of quite small Quantities of alcohol may give rise to the delirious susceptibility. It is possible that a similar deterioration of constitution and consequent lia- bility to trembling delirium may be caused by the opium, chloral, tobacco, and other similar habits; but it is difficult to differentiate these, because of their frequent association with alcoholic excess. Traumatic delirium tremens may follow even slight injuries, but com- pound fractures and burns seem to have a special tendency to develop this serious complication. Its occurrence should not be ascribed to the restraint imposed upon the patient's habits by the injury, but to a trau- matic disturbance of a previously unstable nervous equilibrium. The medical authorities vary in their appreciation of the causative influence exerted by sudden deprivation of accustomed stimulants in exciting attacks of ordinary delirium tremens. It is probable, however, that in a vast majority of such cases the directly exciting causes are the deficient assimi- lation of food, the anxiety and the nervous strain which go hand in hand With a period of debauch, and which persist after the ingestion of alcohol is stopped. Neither is the recurrence of the malady to be imputed to the directly poisonous effect of a large amount of consumed alcohol, since acute alcohol poisoning in persons unaccustomed to the use of alcohol gives rise to stupor and death, but not to delirium. Traumatic delirium tremens occurs because obscure chronic changes in the nervous tissue or blood, or perhaps in both, have rendered the alcohol drinker susceptible to such an outbreak upon the application of any dis- turbing influence. The receipt of injury is a sufficiently perturbing force, especially if the patient be on the verge of an idiopathic attack. It has been thought that the use of beverages containing amylic alcohol (fusel oil), especially predisposes to delirium tremens. PATHOLOGY..—The alteration in nerve structure or blood, which is the essential pathological factor of delirium tremens, is unknown to us. An 216 DISE ASES AND IN J U RIES OF NERVO US CENTRES. abnormal amount of serum is usually found in the substance and within the ventricles of the brain, meningeal congestion and hemorrhage are often seen ; the cells of the gray matter, the cerebral connective tissue, lymph spaces and vessels show sclerotic or fatty changes, and the liver, kidneys, and digestive tract exhibit the characteristic lesions found in chronic alcoholism, but there is nothing to which we can point as the distinctive lesion of delirium tremens. SYMPTOMS.–The initiatory symptoms of traumatic delirium tremens are sleeplessness at night and slight tremor, which is readily noticed by ordering the patient to hold out the hand with widely distended fingers. Subsequently restlessness, insomnia, and tremor increase, and delirium is shown. The delirium, which is often first exhibited at night, is peculiar. The patient sees numerous small animals or insects creeping over the bed and about his person, or is pursued by some hideous spectre. Hence, he is constantly endeavoring to eject the vermin from his clothing, or trying to escape the persecutions of his tormentor. He may, in his efforts to get rid of these disgusting and distressing annoyances, leave his bed and fall from a window or down a flight of steps. The mental condition is one of depression, trepidation, and great activity. He is exceedingly restless, and is constantly chattering in a low tone; but though he may cry out because of fear, he shows little or no maniacal excitement. He is good- natured. not prone to violence, and can often be aroused by emphatically spoken words to an understanding of his surroundings; but he soon relapses into the previous incessant chattering and motion. Very often a single idea recurs again and again to his delirious fancy, and not infrequently the delirium has a comical or tragico-comical aspect. The muscular tremor is not like the twitching of tendons seen in asthenic conditions, but resembles the shakiness, from want of coördination, seen in cerebro-spinal sclerosis. Often there is hurry in movement, and the limbs or tongue will then be thrust forward with a jerk. The tremor of delirium tremens reminds one much of the movements that would be expected in an asso- ciation of chorea with sclerosis of the nervous centres. During these symptoms the patient is unable to sleep, is incessantly in motion, and has a bright eye with dilated pupils and an unsteady, rest- less look. He exhibits a moist, flabby, tremulous tongue, with a whitish fur; desires no food; has constipated bowels, and passes a scanty, high- colored urine. In idiopathic delirium tremens of moderate severity there is no great acceleration of the pulse, and the temperature does not rise much above 100°, except during active muscular exertion. In those graver cases, which Magnan calls febrile delirium tremens, the bodily heat is apt to remain in the neighborhood of 102°–105°, though there is no incurrent affection to keep up the temperature, and the pulse rate is also increased. In traumatic delirium tremens the constitutional disturb- ance, due to the wound, affects the pulse and temperature. The patient will often remove the dressing from his wound, or subject the injured limb to violent motion without appearing to experience pain. Traumatic delirium tremens, as a rule, arises within two or three days after the receipt of injury and lasts usually not more than five or six days. The illusions are apt to continue during the night, even after the patient has become convalescent and quite rational in the daytime. DIAGNOSIS.—The peculiarity of tremor and delirium renders the diag- nosis easy, except from the condition called above nervous or asthenic traumatic delirium. The existence of the described symptoms is, there- T R A U M A TIC I) E I, IIR IU M T R E M E N S. 217 fore, not absolute evidence of previous habits of stimulation, since it is possible that great nervous strain prior to injury may lead to a similar delirium. Usually, however, alcohol seems to be the predisposing cause, though it is not always wise to mention the suspicion, nor to call the disease delirium tremens, since the patient's friends may be unaware of the existence of such habits. PROGNOSIS.—Death may occur from exhaustion, coma, or some inter- current affection ; and is sometimes inexplicably sudden. The character of the traumatism may determine the mode of death. Pneumonia is fre- quently associated with delirium tremens. It is often, in fact, the exist- ing cause of the delirious outbreak, and, of course, in traumatic cases greatly diminishes the chances of recovery. When the temperature shows a tendency to remain high without a sufficient traumatic cause, and espe- cially when the tremor affects all the muscles of the trunk as well as those of the head and extremities and is not arrested during sleep, the prognosis is bad. A history of previous attacks of the disease renders the outlook more grave. - TREATMENT.-It is important to bear in mind that delirium tremens is an asthenic condition. There is action, but it is the activity of weakness not of power. Depressants are, therefore, injurious. Five or ten grains of calomel or one or two Seidlitz powders may be administered in the beginning of the disease, or when its occurrence is feared, because of the anorexia and gastric derangement. Concentrated liquid food with bitter tonics and capsicum add to the patient's strength and tend to give tone to the impaired digestive organs; bathing, Turkish baths if possible, and mild diuretics may be prescribed in the endeavor to eliminate the alcohol that has entered the system. Hydrate of chloral (gr. x-xx) with bromide of potassium (gr. xxx– xl) should be given every two or three hours as soon as sleeplessness and slight tremor is noticeable. No visitors should be allowed in the room. If the development of the attack is not prevented, the same treatment is continued, but the dose may be increased. The object is to quiet the nervous system and produce sleep. In this endeavor an occasional dose of morphia (gr. 4–4) may be combined with the chloral and bromide of potassium. The excessive use of opiates is undesirable for it is not nar- cotism that is desired, but sleep. Cerebral congestion is induced by over- dosing with morphia. If fatty heart exists opiates should be pushed, perhaps, rather than the chloral and bromide of potassium. The com- bination treatment by the three hypnotics allows the surgeon to diminish or increase each element according to indications. Tincture of digitalis (m. X-m, XXX) is valuable in cases of weak but not fatty heart, where there are pallor and cyanosis with probable anaemia of the brain. Strychnia has been recommended in delirium tremens. Hyoscine hydrobromate (gr. Tºw) and other hypnotics may prove serviceable. Mechanical restraint with straps and the straight-jacket is only to be adopted when efficient watching and soothing by attendants are imprac- ticable. All such apparatus excites the patient and is very liable to in- terfere with respiration. The best appliance is a loose, but strong, gar- ment consisting of trousers and shirt in one piece, with loops attached for fastening the patient in bed. Fractures should be dressed with plaster- of Paris bandages, because ordinary splints will probably be displaced by the patient. If failure of vital powers is to be feared, alcoholic stimu- lants in small amounts, administered only when food is given, are judi- 218 DISE ASES AND IN J U RIES OF NERVO US CENTRE S. cious, because in chronic drinkers digestion will sometimes not go on efficiently without the aid of alcohol. The failure of assimilation in delirium tremens may turn the scale against the patient. Whiskey or brandy (fāij to fiv daily) in the form of milk punch or eggnog is . probably the best form of administration. Many patients will not require any stimulants whatever. Vomiting occurring in delirium tremens is to be treated by milk and lime water, cracked ice, effervescing drinks, submitrate of bismuth, pep- sin, and carbolic acid mixtures. Nervous traumatic delirium is to be treated by bromides, chloral, hyos- cine, and nerve tonics, and presents a favorable prognosis. Septic or inflammatory traumatic fever requires judicious antiseptic treatment to combat the local infection with septic products; cold to the head and hypnotic remedies. It occurs when the septic fever is at its height and is often more conspicuous at night; resembling in this latter respect alcoholic traumatic delirium. C H A P T E R XVI. DISEASES AND INJURIES OF THE HEART AND BLOODVESSELS. DISEASES AND INJURIES OF THE HEART AND PERICARDIUM. Wounds of the Pericardium and Heart. PUNCTUREs and small incisions of the pericardium, if uncomplicated with injury to the internal mammary artery, heart, or lungs, present no marked symptoms, and are usually soon repaired by a local pericarditis. Such wounds are made almost with impunity in treating pericardial effusions by aspirations and incision. Larger wounds are much more serious by reason of the suppuration that is liable to occur and the involvement of neighboring structures. The treatment of pericardial wounds consists in rest, antiseptic dressings, and, if suppuration takes place, free exit for the pus by incision, drainage and frequent irrigation. If pericardial effusion occurs after a contusion or laceration of the membrane, blisters, diuretics, and hydragogues should be employed as in rheumatic pericarditis. If the effusion persists and the symptoms become urgent, pericardicentesis should be performed. Wounds of the heart are generally, but not necessarily, fatal. Patients have survived many years with foreign bodies buried in the cardiac walls. The diagnosis is obscure, though signs of internal hemorrhage, or profuse external bleeding with syncope, or great shock, with irregular and feeble action of the heart occurring after a wound of the pericardium make it probable that the heart has been injured. Small cardiac wounds may not be followed by much bleeding, because the peculiar interlacing of the muscular fibres causes the opening to be closed as by a valve. In other cases the pericardium may become filled with blood to such an extent as to make the cardiac sounds and beat almost imperceptible. Death may arise from interference with the heart's action in this manner when the wound itself is not necessarily fatal. The hemorrhage from the heart may be slow or be arrested by a clot forming in the orifice. This may be washed out when reaction from shock occurs and secondary hemorrhage and death thus take place. Men may even walk after wound of the heart. Dyspnoea, pain, pericardial distress, and a systolic-bellows sound have been observed in heart wounds, but these Symptoms and signs are not always present. It should be remembered that the heart lies obliquely between the upper margin of the third costal cartilage and the top of the sixth cartilage, and that it extends from a line about one inch inside of the left nipple to a point a little beyond the right margin of the sternum. Wounds of the auricles are more dangerous than similar injuries to the ventricles. Wounds of the heart must be treated by absolute rest in the supine position, by cold to the front of the chest, morphia, atropia, and digatalis. hen it is certain that clots in the pericardium are doing harm, incision of that sac, removal of the clots, and antiseptic injections may be advan- 220 DISE A SES A N L) IN J U R IB S OF H E A R T . tageous. Experimental suture of the heart has been done successfully, it is said, in the lower animals. I should not hesitate to open the pericar- dium and attempt to suture a heart-wound in the human subject, if evi- dence of such a wound was strong. Resection of the costal cartilages might be necessary in order to gain access to the parts. Tapping the Pericardium or Pericardicentesis. In pericarditis with effusion, and in cases of hydropericardium from renal disease, the pressure exerted upon the heart by the accumulated fluid is at times a mechanical cause of death. Hence, it may become, necessary to withdraw the fluid by aspiration. In all cases of pericardial effusion which present dangerous symptoms of heart failure, aspiration should be performed as soon as it is evident that medication is not lessen- ing the embarrassment of the central organ of circulation. It is bad prac- tice to delay operation until exhaustion, pulmonary engorgement, and degeneration of the cardiac muscle render permanent relief impossible. A moderate quantity of serum suddenly effused will exert more pressure on the heart than a much larger amount poured out in so gradual a manner as to allow the pericardium to become stretched. Hence, the symptoms, and not the amount of serum, must be the guide to operation. If there coexists pleural effusion of considerable amount, the pleural sac should be aspirated first, because it is difficult to discriminate between respiratory distress due to pulmonary pressure and that resulting second- arily from interference with cardiac action. This rule applies to pleurisy of the right side as well as of the left. When the amelioration of symptoms following pericardial aspiration is not permanent, because reaccumulation takes place, the operation should be repeated. It is better to vary the point of puncture, lest, on account of adhesion of the layers of pericardium at the original point, the heart be wounded at the second tapping. Should repeated tapping be demanded, I should be inclined, after the third operation, to inject some irritating fluid, such as tincture of iodine, into the sac, with the idea of producing adhesion of the two layers of pericardium. When aspiration has shown the pericarditis to be distinctly purulent, it is practically certain that repetition of the operation will be demanded. In such an event the introduction and retention of an antiseptic rubber drainage-tube, after a free incision has been made, strike me as the most judicious kind of surgery. The cavity can be washed out daily with anti- septic solutions, and purulent accumulation with its attendant dangers of pressure on the heart and septicæmia avoided. Incision may be useful in certain cases as a diagnotic procedure, when doubt exists as to the condition being dilated heart or pericardial effusion. The best point for aspiration' of the pericardium is in the fifth inter- space, just above the sixth rib, about five or six centimetres (2–2} inches) to the left of the median line of the sternum. In a child it should be nearer the sternum. The ordinary aspirating needle or the aspirating trocar which I have devised may be employed. In all cases the vacuum chamber should be attached to the puncturing instrument as soon as its point is buried beneath the skin, in order that the flow of fluid may indi- cate the moment when the pericardium is entered. 1 Paracentesis of the Pericardium, by John B. Roberts. Philadelphia, 1880. H E M O R. R. H. A. G. E. 221 The pericardial aspirating trocar recommended consists of a moderate size aspirating needle, within which slides a canula with a flexible end. During penetration of the chest wall the canula is retracted, so that the FIG. 81. - ------ * - - A n y g - - - - *-* ...

Afterward it is thrust for- ward to guard the sharp point of the needle and prevent scratching of the heart's surface when withdrawal of the fluid causes the pericardial sac to collapse. DISEASES AND INJURIES OF THE ARTERIES, VEINS, AND CAPILLARIES. Hemorrhage. DEFINITION.—An escape of blood from the vessels is called hemor- rhage, and is either spontaneous or traumatic. When the blood is dis- charged, not upon the surface of the body or into a cavity, but into the meshes of the connective tissue, the term extravasation is generally used. An extravasation into the connective tissue beneath the skin is often designated a subcutaneous hemorrhage. VARIETIES.–Traumatic hemorrhage is primary when it immediately follows the receipt of wound ; intermediary when it occurs after reaction from the shock of injury, and before the lapse of twenty-four hours; and secondary, when it takes place between the end of the first twenty-four hours and the completion of cicatrization of the wound. Intermediary, often called recurring, hemorrhage arises because the force of the circulation has, from the establishment of reaction, become sufficient to displace the clots which, during the previous condition of feeble circulation, prevented bleeding. It may, therefore, occur from small vessels that did not, at the time the wound was dressed, seem to demand ligatures or other treatment; or from larger ones to which ligation, torsion, or acupressure was carelessly or imperfectly applied, or in which the wound was so small that no hemor- rhage supervened until the circulation had fully regained its force. Secondary hemorrhage may be due to any constitutional condition, such as hematophilia, septicæmia, pyamia, hepatic disease, and renal dis- ease, which interferes with the plastic changes and organization of the internal clot that constitute Nature's method of permanently sealing wounded vessels. Hence, when the ligature is absorbed, or the wail of the vessel ulcerated through at the point of ligation, bleeding supervenes. Secondary bleeding may also be caused by an unrecognized contusion or abrasion of the vessel wall which has subsequently given away at the injured spot, by failure of the surgeon to secure the distal end of the artery or to tie a wounded branch situated just above the ligature. In the last two instances the establishment of the anastomotic circulation may be followed by bleeding. Sloughing in the wound, atheroma of the arterial wall, septic processes due to septic ligatures or dressings, badly applied ligatures, premature softening of a ligature, and the rush of the 222 ID IS E A SES AN ID IN J U R I ES OF BI, O O D W E SS E L S. blood-current through a large branch given off just above the point of ligation are frequent cause of secondary hemorrhage. Secondary bleeding usually does not occur earlier than one week, or later than three weeks after the time of injury or operation. Septic causes are responsible for the majority of cases of secondary hemorrhage. Aseptic surgery has almost made secondary hemorrhage unknown. This serious complication must, therefore, be carefully provided for about the fourteenth day, especially after ligation of arteries in continuity for aneurism. In such cases the secondary hemorrhage is more apt to occur at the distal than the cardiac side of the ligature, because internal coagulation and cellular changes occurring there are less effective than in the proximal or cardiac portion of the artery, and probably, also, because the ligature interferes with the small vessels supplying the arterial coats below the seat of constriction. The rapid healing of wounds under aseptic and antiseptic treatment has made secondary hemorrhage much less frequent than formerly. The occurrence of profuse secondary bleeding is generally preceded by a slight flow of blood, which, when observed during the progress of cica- trization or suppuration, should always be looked upon as a warning of grave import. There may be several slight hemorrhages from the wound, and then, when the surgeon flatters himself that he has nothing further to fear, a profuse bleeding quickly destroys the enfeebled and anaemic patient. The treatment of secondary hemorrhage is of exceeding impor- tance, and will be considered after the discussion of the treatment of pri- mary bleeding. Blood starts from a wounded artery in a rapid stream, and, as each beat of the heart gives an increased impulse to the blood-current, the jet gains force, and is propelled further synchronously with the cardiac pul- sations. The blood is of a bright-red color, unless the patient is deeply anaesthetized or partially asphyxiated; then respiration and oxygenation are imperfectly performed, and the blood is dark. When an artery has been completely divided, the hemorrhage from the end further from the heart may not be rhythmical until the collateral circulation is well estab- lished. Venous hemorrhage is characterized by a steady flow of dark blood, which is not affected by the heart's action. The stream may show a ten- dency to rise and fall in a sluggish manner with each respiratory act, but never spurts. If the bleeding occurs at the bottom of the wound the blood may become reddish from admixture with air before it reaches the surface. Hemorrhage from capillary vessels, called parenchymatous hemor- rhage, occurs as an oozing of blood. The steady stream has a color less red than arterial and less purple than venous blood. CAUSES.–Solution of continuity of vascular walls is the common cause of hemorrhage, but bleeding does occur at times from mucous and serous surfaces without apparent lesion. Here the quality of the blood is prob- ably at fault. Cirrhosis of the liver and poisoning by phosphorus and some other substances are said to cause this form of blood transpiration. It must be recollected that hemorrhage from any part may be vicarious to menstruation or other customary loss of blood. CoNSTITUTIONAL EFFECTs of HEMORRHAGE.-It is exceedingly im- portant that the surgeon should recognize the general symptoms of hemor- rhage. In certain cases no blood is visible externally, though a sufficient quantity to cause fatal anaemia has been poured out into the intestines, uterus, or abdominal cavity; or into the cellular tissue surrounding the H E M O R. R. H. A. G. E. 223 perforated vessel. Such concealed hemorrhages are to be recognized by the constitutional effects produced by the withdrawal of blood from the vascular channels. The general symptoms of hemorrhage are influenced by the constitu- tional characteristics of the patient and the vessel from which the blood flows, but depend more especially upon the quantity of blood lost and the rapidity of its escape. An insignificant bleeding may prostrate even to syncope a debilitated or frightened subject, while a considerable hemor- rhage will in some others give rise to no prominent symptoms. Children and the aged are very impressible by loss of blood. Arterial hemorrhage may be expected to produce greater depression than a similar loss from veins, for the obvious reason that venous blood is, in a certain degree, an effete fluid. When a violent and profuse gush of blood occurs from rupture of a large arterial trunk, death is rapid. The blood in all the arteries has a recurrent tendency, and, instead of being forced by arterial and cardiac contraction into the peripheral vessels, it flows toward the wound; hence there is a consequent venous stagnation which gives a livid tinge to the otherwise pallid surface. The patient, who has fallen to the ground in a state of syncope, gasps for breath, throws his limbs about restlessly, and, after convulsive twitchings of the facial and other muscles, expires. Profuse hemorrhage from a large venous trunk causes death in a some- what similar manner. A less impetuous loss of blood, whether arterial or venous, causes a feeble and rapid pulse, sighing respiration, pale con- junctivae and lips, a cold clammy skin, dilated pupils, restlessness, and a confused mind. The patient feels weak and thirsty, is giddy, has im- paired vision and hearing, or, perhaps, sees luminous spots or hears unusual noises, experiences a sense of suffocation, but feels no special pain, and rather suddenly loses consciousness. During this state of syn- cope the breathing is almost entirely diaphragmatic, and the heart's pulsation can scarcely be detected. This lowering of circulatory tension gives an opportunity for coagulation in the wounded vessel, and the bleed- ing is arrested. The patient now recovers from the condition of insensi- bility, and, perhaps, vomits as he returns to consciousness. The increasing force of the heart's action, however, is soon sufficient to cause the blood- current to force the clot from the interior of the injured blood vessel, and hemorrhage, with the train of symptoms mentioned above, recurs. This alternation of bleeding and spontaneous arrest is kept up until death occurs from anaemia of the nervous centres. Sometimes delirium, con- Vulsions, and hemiplegia precede the fatal termination. In very slow hemorrhage there arises great debility, with waxy-looking skin, oedema of the dependent parts, and a tendency to syncope on assuming the erect posture. After death from prolonged or repeated hemorrhage the tissues are Soft and flabby, because the fluids have been absorbed to fill the emptied blood vessels. This explains, also, the thirst felt by the patient. After serious hemorrhages have been stopped a stage of reaction often supervenes, to which the name hemorrhagic fever has been applied. The symptoms are febrile manifestations and a frequent, quick pulse, accompanied by irrita- bility and restlessness of mind and body. Occasionally hemorrhage is followed by a chronic anaemia, which is extremely rebellious to treatment. The febrile state, above mentioned, is to be met by rest, sponging the surface, cold to the head, nutritious fluid food, and tonic remedies. 224 DISE A SES A N ID IN J U R IES OF B L O O D W E S S E L S. NATURE's MoDE OF ARRESTING HEMORRHAGE.--Obscure is the means by which spontaneous cessation of hemorrhage is determined in those unusual cases of oozing, without apparent lesion of the bleeding surface, which have been mentioned. Hemorrhage, from vessels in whose walls a solution of continuity has been produced by accident or operation, often ceases spontaneously. It usually does so in veins, except those of great calibre, and in arteries smaller than the radial and facial. The method employed by Nature in arresting hemorrhage is the same in arteries and veins, though in the latter the sluggish blood-current does not demand such active contraction and retraction of the walls of the vessel. When an artery has been completely divided, Nature promptly insti- tutes steps, which are intended to cause a temporary arrest of the escape of blood until a permanent occlusion of the open extremity can be accomplished. The same series of changes occur in both the cardiac and distal ends of the cut vessel. The temporary means consist of: (1) Con- traction and retraction of the cut end; and (2) clotting of the escaping blood in and around the sheath of the vessel. The permanent means are: (1) The formation of a clot within the artery; (2) plugging of the orifice and union of the edges of the cut extremity by the ordinary process of repair; and (3) cicatricial contrac- tion of the walls of the vessel by which an impervious fibrous cord is produced. TEMPORARY MEANS.—The contraction of the walls of the vessel, which extends up to the first branch, gives its section a flattened or ovoid shape, and, by diminishing the calibre, lessens the size of the blood- stream. At the same time, the retraction of the cut end of the artery within the sheath leaves a space between it and the wound in the non- retractile sheath, which detains the escaping blood and encourages coagulation. Coagulation also takes place outside of the wounded sheath. Lacerated vessels, by the irregularities of the torn ends and of the sheath, encourage this clotting, and may even, if large, soon stop bleeding. º FIG. 82. CLOT IN SHEATH ºłse-- § ºr. Pºrt- º: É: i. T º l ; * łł * 22 #. : 'OU # # O !"OUTSIDE ; $ ARTERY Diagram of Nature's temporary method of arresting hemorrhage. These provisions of Nature may at first fail to stanch the bleeding, because the force of the heart is sufficient to drive enough blood through the contracted vessels to wash away the intra- and extra-vascular clots. As the continuing hemorrhage increases the coagulability of the blood and weakens the cardiac power, perhaps to syncope, the time arrives when these temporary expedients of Nature stop the flow. Cardiac strength then returns and may, by the increased intravascular pressure, cause recurrence of the bleeding. In many instances, however, the tem- H E M O R. R. H. A. G. E. 225 porary means are effective until permanent changes can be brought about to repair the vascular traumatism. PERMANENT MEANS.—When a temporary check has been given to the flow of blood, a coagulum gradually forms within the artery. This is conical in shape, with its base situated and fixed at the opening, while its apex, lying loose in the lumen of the artery, extends as high as the first branch. The base of this internal clot corresponds in size with the in- terior of the vessel, which it fits like a cork. FIG. 83. Aft Aft AE Aft Aft sheath | internal clot Diagram of intermal clot formed in Nature's method for the permanent arrest of 9 hemorrhage. After the deposition of this internal coagulum, and sometimes without its formation, for it may occasionally be 'absent, an exudation of inflam- matory lymph occurs in the stump of the artery and around it and the sheath. This plastic material unites the edges of the wound and seals the orifice by a button-like plug of exudate. The internal blood coagulum is at its base more or less intimately associated and commingled with the plastic deposit. Organization of the exudate, disappearance of the blood- clot, and permanent cicatricial contraction of the vessel to the first im- portant collateral branch go on until finally from the first branch above nothing remains but an impervious fibrous cord. Hemorrhage from a wound partially dividing an artery is controlled in a similar but not identical manner. Contraction and retraction of the vessel cannot occur; but blood is effused within and around the sheath and thus, unless it rapidly escapes to the exterior of the body, causes pressure upon the wounded artery. This causes temporary arrest of the blood escape. An internal coagulum may then be formed. Lymph is subsequently effused, the cavity of the vessel is occluded, and fibrous metamorphosis with obliteration of the vascular channel is permanent. When the wound is less in extent than one-fourth the circumference of the vessel, or if it is longitudinal and consequently gapes very little, hemorrhage may cease and repair occur by plastic exudation, without much encroachment upon the lumen of the vessel. In such cases, how- ever, the internal and middle coats are seldom firmly united, and the force of the circulatory current is very apt eventually to cause stretching of these tunics. Thus may arise traumatic aneurism. CoLLATERAL CIRCULATION.—When the passage of blood through an artery is arrested by division, ligation, or any form of obstruction, the parts beyond receive, at first, less blood. As a consequence, absence of pulsation, lowered surface temperature, and impaired muscular power re- Sult. Soon, however, the anastomosing branches and capillaries of the same and of the neighboring arteries dilate by a vital process and carry more blood to the part than is normal. This is shown by increased red- 15 - 226 DISE A SES A N D IN J U R I ES OF B L O O D W E SSE L S. ness and unnatural elevation of temperature, which, in the case of ob- struction of large arteries, only occurs after the lapse of many hours. After a time the duty of supplying the distal region becomes relegated to a few branches, which remain permanently enlarged. The functions of the part are then carried on exactly as they were previous to interference with the blood-supply. Collateral circulation after wound of artery and ligation. The establishment of the collateral circulation necessitates a reversal of the blood-current in some vessels, but this is not opposed to physiological processes. In aged subjects, whose vessels are apt to be rigid and atheromatous, dilatation of the arteries and capillaries cannot always be rapidly and readily effected, Hence, in such subjects gangrene of the peripheral region from deprivation of blood is more frequent than in the young. The collateral circulation is usually effected by the anastomosis of the branches on the same side of the body and not by inosculation with branches coming from vessels across the median line. Thus, when the right common carotid artery is ligated, the exterior of the head is supplied by the inferior thyroid, a sub-branch of the subclavian, furnish- ing blood to the ramifications of the superior thyroid, a branch of the external carotid. The current in the superior thyroid is reversed, and the blood emptied into the external carotid, which carries it to the face and scalp. The interior of the head is nourished by the vertebral, a secondary branch of the subclavian, communicating within the skull with the cerebral branches of the internal carotid. Little dilatation occurs in the branches inosculating with the corresponding vessels of the left side. H E M O R R H A G. E. 227 When a vein is obstructed collateral circulation is readily established in a similar way. If there is failure in effecting this result, venous con- gestion and oedema occur in the parts below, and may be the cause of moist gangrene. HEMORREIAGIC DIATHESIS.–In some persons a peculiar constitutional tendency, often inherited, causes profuse and almost uncontrollable bleed- ing from slight wounds, such as simple punctures and tooth-extraction. Spontaneous hemorrhage from the nostrils, kidneys, intestines, or bron- chial tubes, and large extravasations into the cellular tissue after bruises, may occur in such subjects. Hemorrhagic diathesis or hematophilia is usually exhibited in childhood, and is frequently unknown until a trivial injury discloses its existence, for such patients often enjoy vigorous health. A liability to joint affections similar to rheumatism, and to inflammations of the lungs, has been said to coexist with the hemorrhagic diathesis. As age advances the bleeding tendency may disappear. In some instances there are attacks of spontaneous hemorrhage, though wounds may be in- flicted with impunity in the intervals. Males are much more frequent subjects of hematophilia than females. The cause of the condition is unknown. There at times appear to be de- ficient coagulability of the blood, and unusual thinness of the internal coat of the vessels. The tendency to hemorrhage is to be combated by saline laxatives, iron, ergot, lead, and opium. Quinine in large doses has been recom- mended. All operations are to be avoided. If wounds occur and bleed, pressure by bandage, ligature, or acupressure must be employed. The actual cautery is a valuable local agent. TREATMENT OF HEMORRHAGE. Constitutional Measures.—Before referring to the local means of checking hemorrhage, the constitutional or general measures must be mentioned; though they are much less im- portant. It is, in fact, only after the bleeding vessels have been con- trolled, or when hemorrhage is feared, but has not yet occurred, that general measures obtain much consideration. The patient should be kept quiet and recumbent, with the head low, in order to lessen the activity of the heart and prevent anaemia of the brain. Sudden elevation of the head may be followed by fatal syncope when much blood has previously been lost. The supply of blood to the nerve-centres can be kept up, in those who have suffered collapse from profuse hemorrhage, by encircling the four limbs with rubber bandages, as in the bloodless method of operating. This drives the entire volume of blood to the head and trunk. The elastic pressure can be continued, as we know from experience in opera- tions, for at Jeast an hour without harm to the extremities thus deprived of blood. If several limbs are bandaged, it is well to remove the pres- sure slowly and from one at a time; lest the sudden rush of blood into the limbs cause recurrent anaemia of the brain. This process is called auto-transfusion, because the patient has his own blood forced into the Centres of organic life. If rubber bandages are not at hand, flannel or muslin bandages may be used; or digital compression of the abdominal aorta or of the subclavian and axillary arteries will prevent the exit of º: to the limbs, and thus leave more for distribution to the head and l’Ull] K. Morphia, quinine, ergot, gallic acid, lead and iron, in full doses, have been recommended as internal hemostatic remedies, but I have little faith 228 DIS E A SES AN ID IN J U R IES OF B L O O D W E S S E L S. in them in surgical hemorrhages. The local treatment is far more impor- tant and effective. In order to diminish arterial tension and thus hasten the arrest of blood, Detmold has suggested temporary withdrawal from the general circula- tion of some of the blood. This is accomplished by applying bandages around the upper arms and thighs with firmness sufficient to prevent venous return, but not so great as to interfere with the ingress of arte- rial blood. The limbs are thus engorged with blood which cannot return to the heart. Hence there is less blood-pressure at the point of hemor- rhage, and spontaneous arrest is encouraged. This device is ingenious, and may perhaps be serviceable in inaccessible hemorrhage of the trunk and viscera. Hemorrhage renders patients thirsty because of the draining of the liquids of the body. Hence water and liquid foods are acceptable and valuable. Perhaps water containing saline ingredients would be prefer- able to simple water. Tonics, stimulants, and concentrated diet should be administered subsequent to profuse hemorrhage, to replenish the loss of the vital fluid. TRANSFUSION.—When death from violent hemorrhage is imminent, transfusion of blood taken from another person who is vigorous and healthy is proper. Venous or arterial blood may be used, and it may be injected into a vein or an artery. Venous blood is generally preferred, because more readily obtainable, and is usually transfused into a vein of the arm. If the blood is transfused from the donor to the receiver with- out being subjected to manipulation, the operation is direct transfusion. The indirect method consists in drawing the blood into a receptacle, re- moving the fibrine by whipping, and, after straining the defibrinated blood, injecting it by a syringe into the circulation of the patient. In performing the operation it is important to avoid the injection of portions of clot, and to prevent the entrance of air into the patient's circulation. The quantity of blood transfused should not exceed eight or ten fluidounces, and should be injected very slowly. It is not unusual for a marked chill to follow the procedure. Direct transfusion is readily accomplished by Aveling's apparatus. This consists of a rubber tube, with a bulb without valves in the centre, and metallic caps with stopcocks at each end; and two canulas or metal tubes for insertion into the veins of the donor and recipient. The canulas can be attached at will to the caps of the rubber tubes by an air-tight joint. When transfusion is to be done, the rubber tube and bulb are filled with warm water and the cocks turned to prevent its escape. The largest vein at the bend of the elbow of the patient is then opened by a flap incision made with a sharp bistoury, and a canula filled with warm water introduced into the vein with the point directed toward the patient's shoulder. The external opening of this canula must be closed by an assistant's finger to prevent escape of the water. A similar vein in the donor's arm is immediately opened and the other canula inserted with its point toward the hand. From this a little blood should be allowed to flow to drive out the air. The rubber tube, or syringe, filled with warm water is now attached to the two canulas and both stopcocks opened. The canulas must be held in place by assistants or by the veins being tied around them. The surgeon with a thumb and finger presses together the sides of the tube at any point between the bulb and the donor's arm, and then compresses the bulb. By this manoeuvre the warm water in the apparatus (fāj) is injected into the patient's circulation. The thumb H E M O R R H A G. E. 229 and finger are then applied to the tube near the recipient's arm, and the bulb is allowed to dilate. Thus about two drachms of blood are sucked out of the donor's arm, and are, by a repetition of the previous process, thrown quietly and slowly into the vein of the patient. If the surgeon refers, he can force the water out of the syringe and let it and the tube fill with blood before connecting the apparatus with the patient's canula. Then no water is transfused, except the very small amount contained in that canula. Apparatus for direct transfusion. Indirect transfusion is accomplished by withdrawing, as in ordinary venesection, about ten fluidounces of blood from the donor and receiving it in a small vessel surrounded by hot water (110°). The blood, thus kept warm, is deprived of its fibrine by whipping with a fork or bundle of straws. After being filtered through a cloth or strainer the defibrinated blood is slowly injected by means of an ordinary syringe attached to a canula, which has previously been inserted into the vein of the patient. The syringe and canula must have the air expelled. Elaborate apparatus has been devised for facilitating these steps, but it is not always possible to obtain such instruments when needed, and the simple means described is efficient. In both modes of transfusion it is often preferable to isolate the patient's vein before opening it, and to apply a ligature around it and the point of the canula after the latter is placed in position. These pro- cedures must be carried on under rigid asepsis. Instead of human blood, lamb's blood, milk, and saline solutions have been transfused with some apparent benefit. LOCAL MEASURES.–In all cases of bleeding the first step is to clean the wound and remove the loose clots. Afterward that means of check- ing hemorrhage is selected which, while securing immunity from recur- rence of bleeding, best assists Nature's efforts and offers least obstruction to rapid healing. When operating, the surgeon should bear in mind that many fluidounces of blood can be lost without very serious injury, and also that no artery or vein can bleed if it is compressed by the fingers. These facts give assurance that there is always time and means to control the bleeding, at least temporarily. Many arteries that spurt freely when 230 D IS E A S E S A N D IN J U R IES OF B L O O D W E S S E L S. first divided soon stop bleeding. Venous hemorrhage usually requires no treatment for it, and unless from large veins, ceases spontaneously. Elevation of the part has a tendency to check arterial bleeding, and loosening of tight clothing or constricting surgical dressings will often cause venous oozing below the constriction to cease. In the first case the force of the arterial circulation is lessened; in the latter the impediment to the upward flow of blood is removed and the consequent distention of the veins prevented. Exposure of the bleeding surface to the air or the action of cold water or ice induces contraction of the vessels and diminu- tion of hemorrhage. Laying open a bleeding cavity or removing the warm, poultice-like clots from a wound has a tendency to check loss of blood from small arteries and capillaries. Ice may be thrust into bleed- ing cavities, but its chilling and depressing influence must be watched. Chemical agents with astringent properties are employed in surgery as blood-arresters, under the name of styptics, because of their tendency to promote contraction of the vessels and surrounding tissues, and because of their inducing rapid coagulation of the blood. The most common styptics are subsulphate of iron, perchloride of iron, alum, the salts of copper, zinc and silver, tannic acid, gallic acid, and various combinations of these with other ingredients. They are employed, either in powder or solution, upon a sponge or piece of cloth, which is applied to the bleeding surface. If the hemorrhage is from veins, capillaries, or small arteries, styptics may arrest it, but are needless because pressure by means of com- presses or bandages is better. If arteries of any importance are the source of bleeding, styptics are inefficient and, therefore, worthless. Hence, as they are either needless or inefficient, and are apt to be means of infecting the wound with bacteria, I regard styptics as useless agents for controlling such bleeding as is met in general surgery. They are objectionable because practitioners resort to them and lose valuable time when ligation, torsion, or acupressure is required. Many of them, moreover, by irritating the surface and covering it with pasty clots, or by infecting it with pyogenic or putrefactive germs, prevent union by first intention. Hot water of about 120° F., locally applied, causes blanching of the surface and cessation of hemorrhage. It has the advan- tage over ice of not depressing the patient. All the methods thus far mentioned are greatly inferior to pressure and to occlusion of each indi- vidual vessel by ligation, torsion, or acupressure. These merit careful description, for they and the actual cautery are the only scientific and satisfactory modes of dealing with the hemorrhages usually observed by the surgeon. When, as in deep cavities without bony walls, it is difficult or impossible to use ligatures or pressure, the cautery iron, heated only to a black or dull red color, may be employed to seal the vessels by converting the tissues into a dry eschar. Lidell advises in parenchymatous hemorrhage water of not less than 160°F. before resorting to cauterization. The water probably acts by coagulating the albumen. Pressure is well adapted for temporarily arresting hemorrhage until ligation, amputation, or other operative measures can be performed. It is also of great value in the permanent arrest of bleeding in those cases when there is no vessel of sufficient importance to require ligation, torsion, or acupressure. In my opinion, pressure and ligation are the only hemo- static agents that the surgeon needs. Applied to the main artery in its continuity, pressure limits the flow of blood to the wound and thus checks H E M O R. R. H. A. G. E. 231 bleeding. This, which may be called arresting hemorrhage by indirect pressure, is generally accomplished by means of a tourniquet, or by pressure of the fingers. The pressure may also be obtained by using a conical bag of shot, or a pyramidal compress with a coin at its apex, or by placing a roll of cloth in the flexure of a joint and bandaging the joint in a strongly-flexed position. These methods are liable to do harm because they often interfere with the return circulation in the veins and thus induce congestion and oedema of the structures between the wound and the point where pressure is made upon the artery. They must be watched. Direct pressure upon the bleeding vessels in the wound is far better. An elastic bandage applied over a crushed and bleeding foot will stop all hemorrhage, and is far better than a tourniquet applied to the femoral artery, because, when reaction occurs and amputation is advisable, all the structures above the injury are in good condition and free from Oedema. A compress and an ordinary bandage, applied evenly and with mode- rate firmness, will arrest hemorrhage from capillaries, veins, and the smaller arteries. A bleeding cavity should be plugged with aseptic gauze or compressed sponge, which may, at times, be held in position with a bandage. No styptic is required, for the pressure causes approximation of the vascular walls, which is followed by internal coagulation, fibrinous exudation, and finally, by obliteration of the vessel. In wounds that are expected to heal by first intention the pressure is made upon the integu- ment, after the parts have been properly adjusted. When healing by granulation is evidently the only method of repair possible, as is the case in wounds made in removing carious bone, the pressure is made upon the open vessels by filling the wound with gauze, and applying a retaining bandage. In using pressure the surgeon must recollect that great force is not required, and that gangrene may result from tight bandaging. The oozing of blood-stained serum through the dressings must not be mistaken for a continuance of the hemorrhage. Enough gauze dressing should be applied to prevent the possibility of this serum reaching the surface, and becoming septic between the surgeon's visits. A considerable degree of pressure may be made with impunity if there is a voluminous gauze- dressing over the wound, because the elasticity of the dressing prevents the constriction from coming directly upon the tissues. When bleeding from a wound is profuse, digital or instrumental pres- sure should be made upon the main artery, while the surgeon is tying or Securing the vessels in the wound. The pressure can then at intervals be relaxed momentarily to allow the bleeding vessels to become distin- guishable. The common carotid artery is controlled by pressure made at the inner border of the sterno-mastoid muscle, on a level with the cricoid cartilage, and directly backward and inward against the cervical vertebrae. The subclavian artery is controlled by pressure made above the clavicle at the outside of the sterno-mastoid muscle, and directly downward, and a little inward against the first rib. The acillary artery is controlled by pressure made along the inner border of the biceps muscle and directed, through the upper part of the artery's Course, outward against the shaft of the humerus. The femoral artery is controlled by pressure made below the middle of Poupart's ligament, and directed upward and backward against the head of the femur and ramus of the pubic bone. 232 D IS E A SES A N D IN J U R IES OF B L O O D W E S S E L S. OCCLUSION BY LIGATION, TORSION, AND ACUPRESSURE.--When hem- orrhage comes from arteries, whose calibre equals or exceeds that of the facial, or from veins which are so situated that pressure cannot be well applied, each vessel must be separately treated. The methods employed to bring the walls of the artery or the vein into apposition, and thus close the lumen, are ligation, torsion, and acupressure. The best and most fre- quently used is ligation. Ligation is simply tying a string tightly around the vascular tube, and thus completely closing its calibre. Ligatures are usually round cords of silk or catgut ; though wire, tendon, and other materials are occasionally employed. Flat ligatures are, as a rule, not desirable. Catgut ligatures are best prepared by the method described for the preparation of anti- septic sutures in the chapter on Essentials of Practical Surgery. They should be kept stored in alcohol, and soaked in a beta-naphthol or subli- mate solution before being used. Silk ligature must be made aseptic by boiling, or antiseptic by soaking in an antiseptic solution before use. A convenient length for a ligature is eight to ten inches, since such a cord can be readily drawn into a firm knot by the fingers. When an artery is tightly tied with a ligature the external coat is deeply grooved by the constricting cord, while the middle and inner tunics are, on account of their brittleness, cleanly divided. The coats thus cut curl up more or less within the lumen of the artery, and aid the coagulation and fibrinous exudation which permanently seal the vessel. If the liga- ture is septic, or becomes so, the external coat of the vessel gradually ulcerates at the constricted point, so that, in the course of a few days or weeks, the noose of thread is found lying loose in the wound. Sometimes a little slough from the external coat is found in the noose when the liga- ture becomes detached. Aseptic or antiseptic catgut and similar absorb- able ligatures become absorbed in a week or two, and do not cause ulcer- ation of the outer tunic. Wire and silk ligatures, if not septic, may become encysted. Septic wounds are more liable to secondary hemor- rhage than aseptic wounds, because of this possibility of ulceration and sloughing occurring in the vessels. Veins have such pliable coats, that none, as a rule, are divided by the ligature, but all are simply corrugated at the point of constriction. When a divided vessel in a wound is to be ligated the surgeon either seizes the bleeding end with a pair of catch forceps and draws it out from Granny knot, which is never used in Flat or reef knot. (J. D. BRY ANT.) surgery. (J. D. BRYANT.) the cellular and muscular tissue in which it is imbedded, or thrusts 8, sharp hook, called a tenaculum, into the wall of the vessel, or the tissue surrounding it. The vessel is then isolated from other structures, as much H E M O R. R. H. A. G. E. 233 as possible, and the ligature tied beyond the forceps or tenaculum, in a reef, or flat knot. (Figs. 86 and 87.) Care should be taken not to include any nerve in the ligature. The accompanying veins and the muscular tissue around an artery are usually separated from it before the ligature is applied; but in smaller arteries it does no harm to include these in the knot. When the knot is tightened, the forefingers or thumb should be placed upon the string close to the artery and firm, steady traction made. (Fig. 88.) The amount of force required to tie even a large artery is not very great, and it should be done without jerking. FIG. 88. Manner of tightening ligatures. The giving away of the inner and middle coats is often distinctly felt by the surgeon. Ligation, as a rule, merely corrugates the inner coats of the veins. Catgut ligatures should be given an additional third tie, be- cause of the liability of the knot when made with catgut to become loosened; or they should be tied in the so-called friction or surgical knot. The ligature should have both ends cut off about one-tenth of an inch from the knot. The method of applying ligatures to arteries in continuity, for the arrest of hemorrhage at a distant point and for the treatment of aneurism, will be described in the section which treats of the special ligations. There are five rules to guide the surgeon in the use of ligation for arresting arterial hemorrhage: I. In cases of primary hemorrhage do not ligate arteries which are not actually bleeding at the time, but have the patient carefully watched. Reasons for this rule: 1. It is very possible that bleeding has permanently ceased. 2. It is difficult to be sure from which arteries the bleeding came. 3. All manipulations in wounds are to be avoided unless demanded. Exceptions to this rule: 1. When a large vessel is plainly seen pulsating in the wound. 2. When the occurrence of even slight secondary hemorrhage would º be disastrous; as in a very anaemic patient. 3. When, as in transportation, the patient will necessarily be away from surgical scrutiny. & 234 IDIS E A S E S A N ID IN J U R IES OF B L O O D W E S S E L S. II. In cases of primary and of secondary hemorrhage the ligature should be applied when practicable in the wound at the point where the artery bleeds, and not in the continuity of the vessel, Reasons for this rule: 1. It is frequently impossible to know which artery is injured until the wound is opened. 2. Secondary hemorrhage may occur, even after ligation in con- timuity from the establishment of the collateral circulation. This secondary bleeding may come even from the proximal end of the cut vessel, if a branch of considerable size is given oft between the wound and the point of ligation. 3. Ligation in continuity makes a second wound, and adds the pos- sible complication of this wound to the patient's original dangers. 4. Ligation in continuity remains, as a reverse step, still possible, if ligation in the wound fails. Exceptions to this rule : None. III. If the artery is completely severed both ends should be tied ; if it is partly divided or punctured, a ligature should be applied to the vessel on each side of such wound. Reason for this rule: The collateral circulation will probably cause secondary hemorrhage from the distal portion of the vessel, unless double ligation be adopted. Exception to this rule: When the distal end cannot be found, pressure must be made in its neighborhood. IV. If a large artery is wounded near its origin, tie it below the wound, and tie the trunk, from which it arises, both above and below the point of origin of the branch. If a trunk is wounded near the origin of a large branch, tie the trunk with two liga- tures in the ordinary manner, and apply a third ligature to the branch. Reasons for this rule: The force of a large current of blood near the internal coagulum may lead to its displacement, and cause secondary hemorrhage when the silk suture causes ulceration of the external coat, or the catgut or flat ligature is absorbed. Exception to this rule: None. V. When it is impossible or impracticable to tie the vessel in the wound, as in deep wounds of the pelvis, ligation in continuity may be permitted. Torsion consists in occluding the cut end of the vessel by twisting it on its long axis. This is done by seizing the end of the cut artery with a pair of catch forceps, drawing it out of the sheath and giving it four or five sharp rotations. This twisting in the case of large arteries, like the femoral, should be repeated until the sense of resistance has ceased; but the end should not be twisted off. By this manoeuvre the middle and inner coats are lacerated and curl up within the lumen of the artery, while the external tunic is twisted into a cord. This acts as a temporary plug until the internal coagulum and exudation of lymph are enabled to prevent hemorrhage and permanently close the orifice. H E M O R. R. H. A. G. E. 235 The twisted end is sometimes thrown off as a small slough ; but if kept aseptic it becomes blended with the adjacent structures and is converted into fibrous tissue. In dealing with small arteries the ends may be twisted entirely off with impunity. IFIG. 89. FIG. 90.

Some operators perform limited torsion instead of the free torsion just described. Limited torsion is performed by drawing the vessel out and grasping it transversely a little above the end with a second pair of for- ceps. When rotation is then made by means of the first forceps the effect of the twisting cannot extend above the point held by the second pair. This method is convenient when the artery is loosely connected with sur- rounding parts. The chief advantage claimed for torsion is that it leaves no foreign material in the wound as does the ordinary ligature. Aseptic catgut or silk ligatures being either absorbed or encysted do not act as foregin bodies, but allow the wound to be at once closed. It is, therefore, in this respect comparable to torsion; hence, as ligation is much safer than torsion, I greatly prefer ligation to any form of twisting, except for vessels of inconsiderable size. When the hemostatic forceps, used to arrest hemorrhage from cut vessels during the continuance of an operation are to be removed, a few preliminary twists given to the vessels will often avert the necessity of ligature. ACUPRESSURE.-Hemorrhage from a divided vessel may be arrested by introducing a long needle or pin into the surrounding tissues in such a manner as to compress the artery or vein. This compression, called acupressure, may be increased by adjusting a wire or thread around the ends of the pin as in the harelip suture, or by twisting the tissues and the artery during the insertion of the pin. The pins, which must be aseptic, must not be permitted to remain in the tissues longer, at the furthest, than three days. Usually they should be removed in twenty-four or forty- eight hours. The time depends upon the size of the artery. Large arte- ries require longer pressure than small ones, to insure against secondary hemorrhage. Herein lies the chief objection to acupressure. If the pins are removed too soon, secondary hemorrhage may supervene; if they are allowed to remain too long, they may cause irritation or interfere with the dressings, and there is nothing gained over the use of the ordinary ligature. Acupressure is a valuable means of arresting bleeding when the surgeon has no assistants and is in a hurry. It stops the hemorrhage until better methods can be applied. It is also useful as a preliminary to operations which must of necessity divide definite vessels. Thus the facial artery can be compressed before cutting into the cheek. So also the tissues around 236 D IS E A SES AND IN J U R IIES OF B LOO D VES S E L S. vascular tumors can be thus compressed by pins with threads wrapped around the ends before their éxcision is begun. Acupressure acts as a hemostatic by bringing the vascular walls together and thus shutting out the blood current until repair goes on by exudation of lymph at the cut extremity of the vessel. An internal coagulum forms above the point of acupressure, but does not seem to play any part in the function of the permanent repair. Permanent closure is effected entirely below the constriction caused by the pin in the same manner as in nature's method of arresting bleeding and repairing cut arteries. If the pin remains long enough to destroy the structure of the inner coat, the same changes occur as after ligation. Acupressure pins are removed by seizing the head and gently rotating and withdrawing the pin from the tissues while the parts are supported with the other hand of the surgeon. Of the many methods of obtaining pressure upon an artery by means of a needle or pin thrust into the tissues there are only four that deserve special attention and description: 1. The point of the pin is introduced through the skin perpendicular to the course of the vessel, the free end of the pin is depressed, the point is then carried across behind artery until it emerges from the skin at the FIG. 92. º º III, ſº ºft First method of acupressure. (BRYANT ) Second method of acupressure. (BRYANT.) opposite side of the vessel. The elastic skin exerts sufficient'tension upon the pin to cause approximation of the arterial walls. If complete con- striction is not thus induced a silk or catgut thread may be wrapped around the exposed ends of the pin, as is done in the pin or harelip suture. This reinforcement of pressure may become especially necessary when pins are introduced from raw surfaces, in which the elasticity of the skin does not exist. • 2. The pin is thrust through a thick fold of muscular tissue at one side of the vessel, carried across the front of the artery and thrust through a second thick fold of the tissue at the other side. The pin is thus pressed back upon the artery by the tension of the transfixed muscular masses. This method obliterates the calibre of the vessel best when firm struc- tures, such as bone, fascia, or skin, lie behind the artery and furnish counterpressure. 3. The pin is introduced parallel to the axis of the artery through a fold of tissue near one side of the vessel; the free extremity of the pin is rotated in the horizontal plane through one-quarter of a circle, and the point is then carried across the front of the artery and fixed by being deeply buried in the soft structures on the other side. The artery is thus closed by the twisting of its coats and of the surrounding tissues. 4. The pin is inserted at right angles to the axis of the artery through a fold of tissue; the point is then carried across the front of the artery, and the free extremity of the pin rotated in the vertical plane through a half circle and the point fixed by being deeply buried in the soft struc- H E M O R. R. H. A. G. E. 237 tures behind the vessel. Occlusion is accomplished somewhat as in the previous method by the twisting induced by the rotation of the pin. FIG. 93. Third method of acupressure. FIG. 94. Fourth method of acupressure. Acupressure is, in my opinion, far inferior to ligation, which method, when aseptic catgut or silk ligatures are employed, secures the greatest safety and has no tendency to retard primary union. When it is difficult to apply ligatures or acupressure in deep wounds, the hemostatic forceps may be used to seize and close the arterial wound and then be allowed to remain so attached as clamps for one or two days. If aseptic they do no harm, except to make dressing of the wound a little inconvenient. TREATMENT OF SECONDARY HEMORRHAGE.-The prevention of sec- ondary hemorrhage is to be secured by obtaining rapid union in wounds. Hence, absence of pus is a primary factor. Consequently antisepsis and provision for free drainage are absolutely demanded. When secondary bleeding is feared the patient should be kept abso- lutely quiet, and undue circulatory activity controlled by aconite, low diet, laxatives, and possibly venesection. Morphia and ergot given in- termally in full doses are beneficial from this point of view. So also is partial compression of the main arterial trunk supplying the injured region, and elevation of the limb in which bleeding is feared. In dealing with secondary hemorrhage the surgeon must not delay. In primary hemorrhage it is injudicious to take active steps when bleeding has already ceased, unless the circumstances are exceptional. The case is different in secondary bleeding. The first escape of blood, even in small 238 DISE ASES AND IN JURIES OF BLOODVESSELs. quantity, calls for action, which may, it is true, be limited to elevation of the part and compression of the wound and main artery by compresses and bandages; but the second actual outbreak of hemorrhage impera- tively calls for prompt surgical measures. If healing of the wound is still quite incomplete the sutures should be withdrawn, the clots turned out, and the vessel from which bleeding has come securely ligated. As it may be somewhat difficult to determine the exact source, every sus- picious point should be ligated. If the softened or sloughy condition of the wound surfaces prevents satisfactory application of ligatures, the actual cautery may, perhaps, be available. Opening the wound is the proper procedure even if union is well ad- vanced, for the escaping blood has usually distended the wound cavity before the existence of bleeding has been detected, and by this action, moreover, the surgeon obtains the most accurate information possible of the character of the complication with which he has to deal. Acupressure applied by the first method described on page 236, is often a valuable means of arresting the bleeding either before or after the wound is re- opened. By thrusting the pin deeply through the tissues and reinforcing the pressure with a strong thread wrapped around the ends, the surgeon is enabled to compress parts in which one or more bleeding arteries are situated. This manoeuvre may be employed to avert the necessity of lay- ing open the partially cicatrized wound, or to secure vessels whose patulous mouths cannot be found on the surface of the wound because of spon- taneous cessation of bleeding. 4. Instead of an acupressure pin a strong ligature may be carried through the tissues by means of a long needle ; by tying the ends of this cord together constriction may be effected that will restrain hemorrhage, though not sufficiently great to cause strangulation and gangrene. The elastic bandage applied with only moderate firmness over the wound at times proves a valuable aid in resisting secondary bleeding. When secondary hemorrhage persists despite the direct treatment ap- plied at the seat of trouble, it is proper to ligate the main artery in con- tinuity, as is done in dealing with aneurisms. Such ligation should be performed as near the seat of hemorrhage as possible unless the anatomical relations of the regions make it known that the arterial anastomosis will soon establish such a collateral circulation that hemorrhage will probably recur in the original locality. Then it becomes necessary to select a higher point for the deligation. In secondary hemorrhage of the palm, for example, it is usually better surgery to ligate the brachial artery than to tie at the wrist the radial or ulnar or both ; this is a fact because the anastomosis between the arteries of the forearm is so free. Secondary hemorrhage may supervene after an arterial trunk has been tied in its continuity for the cure of aneurism or the arrest of hemorrhage at a lower point. Here the first step is to apply pressure to the seat of ligation by a graduating compress, or by plugging the wound. If this fails the wound must be opened and a ligature applied at each side of the orifice in the vessel, which must then be completely divided between the ligatures, if the original injury did not do so, in order to allow retraction and contraction of its walls. In the event of this being followed by re- currence of hemorrhage, either a second deligation in continuity at a higher point, with or without contemporaneous ligation of one or more anastomosing branches, or amputation of the limb must be performed. Gangrene is apt to occur when a second ligation is done in the lower extremity, because the collateral circulation is rarely sufficient to main- W O U N DS OF W E IN S. 239 tain the vitality of the distant parts. Hence, some high authorities have recommended amputation rather than second ligations for persistent Sec- ondary hemorrhages under such circumstances. When the original source of secondary hemorrhage is a vessel near the aorta, pressure at the seat of bleeding is the only resource. Indeed, pressure, judiciously applied by pads, plugging, and shotbags, has at times been efficacious when ligation above the seat of hemorrhage has failed. This is due to the circumstance that the escape of blood comes very frequently from the distal portion of the injured vessel, to which the anastomosing branches have given an abundant blood-current. WOUNDS OF VEINS. The discussion of hemorrhage has involved some consideration of wounds of veins, but a few points remain that deserve more extended attention. The dangers from wounded veins are hemorrhage, septicaemia, diffuse phlebitis, and entrance of air into the heart. The bleeding from large venous trunks is as fatal as arterial hemor- rhage, but that from small veins usually stops spontaneously unless there is some source of constriction upon the cardiac side of the wound. Good examples of this are seen in the constricting bandage placed above the elbow in cases of venesection, in order to obtain a prolonged and free flow of blood from the wounded vein; and in protruding hemorrhoidal tumors pinched by the sphincter of the anus, which will continue to bleed until the anus is dilated by the fingers or the tumors replaced within the rectum. Blood flows from wounded veins in a dark, rapid stream without showing the pulsatile action of the heart; it has, however, an increase in its force during each act of expiration, if the seat of hemorrhage is near the trunk. Pressure made on the cardiac side of the wound causes an increased flow of blood. This may be of diagnostic value in deep wounds, for blood from arteries may be dark during anaesthesia, or when the bleeding comes from the distal end of a divided artery in one of the extremities. * Subcutaneous rupture of a vein from violence may occur. The ex- travasation of blood, even if large, is usually absorbed in a few days or weeks; but it may cause inflammation leading to abscess, if pyogenic bacteria gain access to it, or become encysted in a fluid state, giving rise to the fluctuating tumor called hematoma. Contusions of veins, as of arteries, may be unaccompanied by symptoms of special import until secondary hemorrhage occurs from the ulceration or sloughing of the injured vessel wall. When veins are completely divided slight contraction and retraction of the coats occur, but not in a sufficient degree to restrain hemorrhage from the larger vessels. Incision and puncture of veins, when not fatal, usually heal rapidly and perfectly by first intention, leaving no scar and not encroaching on the calibre of the vessel. Such is not the case in arterial wounds which are followed by obstruction of the vessel at the seat of puncture. This is well illustrated by the wound of the median basilic vein made in vene- Section. Small wounds of varicose veins or of the larger trunks may prove fatal from anaemia, if the bleeding is not arrested by pressure or ligation. Injurious secondary results may follow when the blood is poured into the cavity of the cranium, thorax, or abdomen. Often this 240 DIS E A S E S A N D IN J U R IES OF BILO O DW E SSE L S. is the chief danger. Wounds, even of the large cerebral sinuses, are not of very grave prognosis, if the blood is given full opportunity to escape, for moderate pressure arrests the hemorrhage in these venous channels of slow current. Wounds of small or moderate size veins require little special treatment. Elevation of the part, removal of all constriction of clothing on the cardiac side of the injury, and slight pressure by a compress and bandage are sufficient. In three or four days cicatrization occurs. Large veins require ligation. Styptics should never be employed. A catgut liga- ture should be applied below and another above the wound, if the vein is not completely divided; or the wound may be closed by fine catgut sutures. Either of these is perhaps a better safeguard against secondary hemorrhage than lateral ligation. By lateral ligation is meant tying the portion of the wall of the vein immediately surrounding the wound. This is readily done in large veins by grasping the flaccid coats of the vessel with forceps and tenaculum and tying the ligature around the tissue so seized. Such a ligature is possibly liable to slip off; hence suture may in Some instances, at least, be better. Lateral ligature and suture do not entirely destroy the continuity of the vessel as does circular ligation above and below the wound. Aseptic ligation of veins is not apt to pro- duce diffuse phlebitis and pyaemia, as was formerly taught. The method of repair after ligation of veins is similar to that which obtains in arte- rial ligation. The ligature does not, however, cut the internal and middle coats of the vein, but merely corrugates them ; or, at most, divides only the inner layer of the middle tunic. Coagulation then occurs at the distal side of the ligature, and inflammatory changes ensue which permanently seal the vessel. In some cases the bleeding may be satisfactorily controlled by seizing the wounded portion with hemostatic forceps, so placed as to close the opening and leaving them hanging in position for twenty-four or forty-eight hours. Septicaemia may follow venous wounds, if the open vein or sinus is surrounded by unhealthy pus; hence absence of putrefaction and provi- sion for drainage are important features in treating wounds in which large veins are opened. Ligation by closing the open orifices tends to prevent such septic infection, and is, therefore, at times advisable in major operations, when sepsis cannot be prevented, even when there is no lia- bility to venous hemorrhage. When the large veins of the extremities, such as the femoral or axillary, are wounded, ligation of the accompanying artery also may, according to some authorities, be proper and judicious after ligation of the vein. The flow of blood to the limb is thus diminished ; venous congestion of the tissues is thereby prevented, because the equilibrium in the capillaries is less disturbed; and the possibility of gangrene is probably less. Further evidence of the advisability of such simultaneous ligation of veins and arteries is desirable. I very much doubt its propriety in the upper ex- tremity, though willing to admit its probable value in wounds of the femoral vein. Trephining may be required after wounds of the sinuses of the dura mater to allow the removal of clots causing compression of the brain. Moderate pressure upon the injured venous channel with antiseptic cotton will control hemorrhage. Hemostatic preparations of iron or other styptics should not be employed. If from any cause the wound in a vein is kept widely open during violent inspiratory efforts, air may be sucked into the venous circulation W O U N D S OF VE IN S. 241 and be carried to the right heart. This dangerous accident is especially liable to occur during operations in the vicinity of the internal jugular, subclavian, innominate, and axillary veins; though it has been stated that it may happen in veins of smaller calibre and in those situated further from the heart. The manner in which wounded veins ordinarily become collapsed during inspiration usually prevents the entrance of air; hence it is only when some cause holds the lips of the wound apart that sucking air into the veins is possible. This may be due to inflammatory thick- ening of the walls converting the vein into a tube, the so-called canaliza- tion of the veins; to the vessel being imbedded in hardened tissue or in the substance of tumors, which prevents collapse; or to the efforts of the surgeon who, in attempting to enucleate a tumor or foreign body, pulls the walls of the vein apart at the time of a deep inspiration. The acci- dent is less common since the introduction of anaesthesia, because there are less struggling and gasping on the part of the patient, and more delibera- . tion exercised by the surgeon. It is possible, however, that some of the deaths attributed to anaesthesia may be cases of air in the veins. : The symptoms of entrance of air into the veins are marked. During the progress of an operation a sudden sucking sound is heard; frothy blood is, perhaps, observed in the wound, the pulse fails, the heart beats irregularly and feebly, respiration is oppressed, and syncope or, perhaps, convulsions occur. If the amount of air drawn in is small, recovery gradually takes place; if the quantity is considerable, coma and death supervene. The fatal issue may be immediate, but usually is postponed for a period varying from a few minutes to an hour. In cases that recover transitory paresis has been observed. Secondary pneumonia has proved fatal in others. Occasionally a sound similar to that produced by air entering the veins occurs when the deep fascia of the neck is incised, I was once startled by this phenomenon when performing tracheotomy for great dyspnoea in diphtheria. The pathology of the symptoms induced by air in the veins is not understood. It is probable that the air, causing a frothy condition of the blood in the right auricle and ventricle, prevents proper action of the valves and interferes with the blood transfer in the pulmonary circula- tion. Anaemia of the brain and other nerve centres is thus induced." This serious complication of operative surgery, which must be quite rare, is to be prevented by securing regular and quiet respiration during anaesthesia, by tearing the tissues in the vicinity of large veins apart with fingers and dull instruments, instead of using the knife, and by avoiding any posture of traction that tends to keep venous wounds gaping. When it becomes necessary to divide a large vein the surgeon should make pres- sure with the fingers upon the vessel at the cardiac side of the proposed Yound. This should be done also when firmly attached tumors are being forcibly enucleated. It has been proposed to bandage the chest as a pre- liminary measure before operating in the region made dangerous by the situation of the large venous trunks. Thus unexpected deep inspiration is prevented. When air has actually been sucked into the veins, prompt treatment is demanded. The vein should immediately be compressed at the cardiac side of the wound, and ligatures should then be applied on both sides of * See N. Lewis's paper, Amer. Surg. Assn., 1885. 16 242 DIS E A SES AND IN J U R IES OF BLOOD WESS ELS. the orifice. The patient's head should be lowered, stimulants should be given, and artificial respiration instituted. Galvanism of the chest and cardiac region, transfusion of blood or of warm water, tracheotomy, venesection, and pumping the air from the veins or even from the heart by the aspirator, have been proposed. The injection of warm water directly into the heart-cavity has been suggested. If the symptoms depend upon failure of the valve action because of absence of fluid in the heart, this may perhaps be a rational therapeutic IleaSUll’é. It is probable that the dangers of air in the veins and heart have been overestimated. DISEASES OF THE WEINs. Inflammation of Weins, or Phlebitis. VARIETIES.—Inflammation of veins may be plastic or suppurative. Idiopathic phlebitis is quite rare, but occasionally occurs in the course of fevers, or as the consequence of syphilis, gout, varicose veins, and pos- sibly of exposure to cold. This form of venous inflammation is more apt to be located in the veins of the lower extremity than elsewhere, and does not often assume the dangerous characteristics that quite frequently belong to traumatic phlebitis, because traumatic phlebitis is often septic. Traumatic inflammation follows contusion, rupture, or incision of the venous walls, and may also be due to violent muscular contraction and pressure, Uterine phlebitis after parturition is a phlebitis possibly due to the cause last mentioned, but probably a result of microbic infection. Inflammation of the tissues around a vein may cause phlebitis, which should then be considered a form of traumatic phlebitis secondary to peri-phlebitis. Traumatic inflammation of veins in healthy subjects is usually a localized affection of slight gravity. If, however, Septic changes occur in the wound, especially it would seem when the orifices of the divided veins remain open, a diffuse or suppurative phlebitis, allied to pyaemia, and of a most dangerous character may arise. Operation wounds of veins are usually of slight gravity, because the consequent phlebitis is an uncomplicated and localized adhesive inflammation. PATHOLOGY..—Coagulation of blood in the living veins, technically called thrombosis, is always an accompaniment of phlebitis. This clotting may be the cause of the inflammation. Such is the case at times in the phlebitis secondary to varicose veins. Here the overstretched venous walls, with imperfectly-acting valves, allow retardation of blood-current, and the consequent thrombosis sets up inflammation of the vascular tunics. On the other hand, thrombosis may be the result of inflammation, as is probably the case in traumatic phlebitis. The pathological changes of phlebitis occur principally in the outer and middle coats, which in veins, indeed, are scarcely to be considered as two distinct tunics. Hyperaemia of these coats and infiltration of the spaces between their vessels with cells and serum are observed. These changes necessarily induce swelling, thickening and loss of flexibility of the walls, which may remain patulous when divided. The internal coat becomes cloudy, fissured and shreddy, and may be separated from its neighboring tunic by the disintegrating influences of inflammation. At the seat of inflammation coagulation takes place within the vein at an early stage of the phlebitis. If the clot is aseptic and remains so, the IN FLA M M ATION OF VE INS, OR P H L E BITIS. 243 inflammatory process is localized. The vein may then be converted into an impervous fibrocellular cord, as occurs after arterial ligation. If the coagulum adheres to only one side of the vein, however, partial circula- tion may finally be established through the vessel; or, if complete removal of the clot by absorption occurs, the calibre of the vein may be perfectly restored. $ The occurrence of suppurative and gangrenous inflammation of veins leads to disintegration or yellow softening of the clot, and the dangerous septic elements are admitted into the general circulation. As a result, portions of the coagulum are worked loose and carried to the right heart and thence into distant arteries. Such plugs or emboli produce infarctions and abscesses; and because of an infective nature lead to pyaemic symptoms and death. It is for this reason that phlebitis in broken-down subjects or in those suffering from infected wounds, is regarded as a disease of grave prognosis. SYMPTOMS.–Inflammation of a subcutaneous vein gives rise in the course of the vessel to a hard painful cord, which is accompanied by some swelling and a distinct dusky-red or copper color line upon the overlying skin. The cord often has a knotted appearance indicating the situation of the valves of the diseased vein. Coagulation in the vessel impedes venous return from the distal part of the limb and causes oedema, which may be further increased by actual inflammation of the general connective tissue of the extremity. In the latter event, there is more in- duration than in simple oadema from circulatory obstruction. Stiffness of the limb affected with phlebitis and pain, often of a character resembling neuralgia, are present. Phlebitis, when not localized, usully extends in the direction of the heart. When the deep veins only are inflamed the vessels are not mapped out by the subcutaneous rigid cords that serve to distinguish superficial phlebitis, neither are the copperish lines seen ; but the painful stiffness and Oedema are perhaps the only indications of inflammation. The diagnosis, consequently, is sometimes difficult. The constitutional symptoms are slight in localized venous inflamma- tion; but when the disease is more extensive, febrile movement is present. In the event of septic infection occurring in the manner explained in the paragraph on the Pathology of Phlebitis, chills, sweats, high temperature, a rapid thready pulse, and delirium are to be expected. Under such circumstances embolic abscesses and death from pyaemic symptoms may readily supervene. Embolic abscess of the liver may thus occur in portal phlebitis. A close connection exists between rapidly-spreading phlebitis, with its ulceration and gangrene of venous walls, and diffuse cellulitis and erysipelas. They all tend to destroy life by the induction of septi- Gaemic processes; and are due to mycotic infection. Non-septic phlebitis is, even when extensive, of favorable prognosis. Septic phlebitis is a very fatal disease. Phlebitis is to be distinguished from inflammation of the lymphatic Vessels, or angeioleucitis, by the absence of glandular involvement and by the darker red of the cutaneous line indicating the course of the affected vessels. Neuralgia and neuritis are unaccompanied by the oedema which almost invariably attends phlebitis. TREATMENT-Phlebitis is to be treated by absolute rest of the part affected, and by the avoidance of all causes that might favor the separa- tion or disintegration of the intravascular coagulum. Pyogenic and Putrefactive infection must be rigidly averted. Slight elevation of the 244 DIS E A SES A N D IN J U R I ES OF BILO O D W E S S E L S. limbs to favor the return circulation is judicious and lessens pain. Leeching, lead-water and laudanum, mercurial ointment, evaporating lotions, fomentations of various kinds, and tincture of iodine have been found useful as local measures. Quinine, iron, and rest in bed are essen- tial in cases of even moderate severity. Cardiac depressants are to be avoided because of the possibility that septicaemia may arise from unex- pected infection. When inflammation is spreading rapidly up the vein, Mr. Lee suggests compressing the vein at two points—above the seat of inflammation by acupressure pins, and subcutaneously dividing the vessel between them. If suppuration, great oedema, and diffuse cellular inflammation arise, free incisions, parallel to the veins, should be made. This procedure should be followed by thorough antiseptic irrigation and drainage. To remove the swelling and hastem the absorption of inflammatory deposits, due to phlebitis of a chronic type, elevation, friction, massage, and pressure by the elastic bandage should be employed. Bypertrophy and Varicosity of Weins. DEFINITION.—When an abnormal quantity of blood is constantly carried by a vein, the vessel becomes enlarged in calibre and thickened in its coats. This constitutes hypertrophy of veins; and is seen, for ex- ample, when obstruction of a vena cava causes enlargement of the external epigastric vein and the veins of the anterior walls of the chest, and in other instances of unusual development of the collateral venous circulation. No treatment is required, for the condition is a compensa- tory one. When the amount of blood in a vein is diminished, as happens after amputations, venous atrophy results. Varicose veins are veins which, on account of disease of the walls, have become enlarged and more or less irregularly dilated and thinned, and in which the blood current is abnormally retarded. Varix, or varicose vein, is, therefore a condition that should be distinguished from hypertrophy of veins. * PATHOLOGY..—Varicosity is most frequently met with in the veins of the leg, spermatic cord and rectum ; though the condition may arise in any location, even, it is stated, in the veins of Osseous tissue. The long saphenous vein is very frequently affected. The condition is probably due to a paresis of the muscular tissue of the vessel wall depending upon degeneration of muscular fibre or imperfect innervation. Any impedi- ment of the blood current acts as a predisposing cause of varicose veins by increasing the intravenous hydrostatic pressure. Hence gravity has long been regarded as a prominent factor in the production of varix. I doubt whether such causes are capable of giving rise to varicosity, when collateral venous circulation is possible, unless at the same time there be Some degenerative process going on in the venous walls. I should as soon expect to see aneurismal dilatation of an artery produced by simple inter- ference with the blood current without previous disease of the arterial tunics. If the flow of blood is arrested in an artery the anastomosing arteries become hypertrophied; so is it in the case of veins. If the blood current is impeded in one vein, the collateral circulation is established and the adjacent veins become hypertrophic. Heredity, debility, continued standing, the wearing of tight garters, and H Y P E R T R O PHY AND WA RIC OSITY OF VE IN S. 245 many other factors have been accused as causes of varicose veins; but there must be some as yet unknown influence that determines the occur- rence of this pathological venous lesion. The pathological changes found in varix are dilatation, increased length and tortuosity, hyperplasia of connective and other tissues, causing irregu- lar thickening of the venous walls, incompetent valves due to partial destruction of the leaflets, or to the impossibility of contact resulting from the increased calibre of the vessel, and sacculation similar in appearance to the pouched condition of the colon. The irregular dilatations, causing sacculation, are especially prominent at points where two veins unite. The wall in such pouches is exceedingly attenuated. Chronic inflam- matory changes are apt to arise in the tissues surrounding varicose veins, causing oedema, obstinate ulcers and even a condition resembling Arabian elephantiasis. Coagulation may occur within varicose veins, and thus induce inflam- mation or occlusion and partial cure. Suppuration may occur from infection with pus germs. Calcareous - degeneration of the clot sometimes FIG. 95. takes place, and concretions, called vein-stones, or phleboliths, remain. Tº These may be either free or adherent º to the wall of the vein. They are sº also, however, found in veins not vari- cose, and are especially liable to occur in the veins of the pelvis. It is be- Varicose vein. (BRY ANT.) lieved that these pelvic phleboliths may also be formed outside of the vessel and subsequently penetrate the venous walls. SYMPTOMS.–The symptoms of varix are, dull pain, a sensation of weight or fulness, numbness, and perhaps some impairment of power. Inspection shows a characteristic, bluish, knotted, soft tumor, in which the dilated and tortuous veins can readily be recognized. CEdema, indura- tion, eczema, and chronic ulceration of the skin are frequently present in varix of the leg of long standing. It is probable that the deep veins are affected about as frequently as the subcutaneous, but when the affection pertains only to the former the diagnosis is difficult. Gay thinks muscu- lar cramps indicative of deep varix. Slight local varicosities of the cutaneous capillary veins are quite common in women, giving rise to an arborescent appearance of the skin without swelling or other symptom. . Profuse bleeding may supervene from perforation of a varix by ulcera- tion. It is improper to say that the varicose vein bursts, since the ulcera- tive process begins externally. The copious hemorrhage probably comes from the cardiac portion of the vein, which is distended with blood and furnished with diseased valves incompetent to resist the backward cur- rent. Moderate pressure with a finger or compress will control the bleed- ing, which, if not arrested, may prove fatal. Phlebitis, with its characteristic thrombosis, may be developed in vari- Cose veins without any specially assignable cause. TREATMENT.-The distress produced by the existence of varicose veins gan be greatly palliated by such artificial support as is obtained by cover- ing the Jimb with elastic webbing, or a rubber bandage, applied smoothly and with very moderate pressure. To prevent cutaneous irritation from retention of secretion it may be necessary to cover the skin with a soft piece of cotton or linen cloth, before applying the rubber bandage.

These appliances for pressure should be removed at night only after the patient has assumed the recumbent posture. Elevation of the leg while keeping the patient in bed and pressure of this sort will greatly hasten the cure of eczema and ulcers complicating varicose veins of the lower limbs. The radical treatment of varicose veins depends upon occlusion of the calibre of the vessel; or, in other words, upon obliterating the vein at the point operated upon, and thus compelling anastomosing veins to carry on the circulation. The symptoms of varix are removed at the points of operation, and much relief may thus be afforded the patient; but the condition persists, or is soon developed in the adjacent veins, either super- ficial or deep. There is a risk, though an exceedingly slight one, of inducing dangerous phlebitis by these operations, for the so-called radical treatment of varix. Such measures are to be recommended when incon- venience, pain, intractable ulceration, or the danger of hemorrhage from perforation renders the patient uncomfortable. Antiseptic surgery renders these operations trivial. The most approved methods are the subcutaneous ligature and acu- pressure. Subcutaneous ligation is effected by carrying a catgut ligature beneath the dilated vein by means of a straight needle, which is then reëntered at the point of exit and thrust in front of the vein until it emerges at the first puncture. Withdrawal of the needle through this original opening causes the vein to be subcutaneously encircled by a loop of catgut.

The coats of the vein are thus brought into apposition and internal coagu- lation, with consequent local plastic inflammation and occlusion, results at as many points as the surgeon has ligated. The catgut ligatures become absorbed and need no attention. The veins should be ligated at numer- ous points, and care must be taken to avoid transfixing the vessel with the needle. It is well to insert the ligature nearest the heart first and to have the limb dependent, so that the vein may be distended to its fullest capacity. º Acupressure acts in a similar manner. Harelip pins are thrust behind W O U N I) S OF L Y M P H A TIC S. 247 the varicose veins at various points about one inch apart, and the com- pression obtained by a figure-of-eight or elliptical ligature applied as in making the twisted suture. The uppermost pins should be inserted first. The pressure may be increased by laying small pieces of rubber upon the skin at right angles to the pins and tying the ligatures over these.

The pins should be withdrawn after the lapse of eight or ten days. A modification of this method is to compress the vein with pins and then subcutaneously divide the vessel by means of a tenotome. The pins are removed in about four days. Obliteration of the vein is thus insured, and there is little danger of septic phlebitis. It is a good method. Excision of about two inches of the vein through an ordinary cutaneous incision is a successful method. It must be done aseptically. After any of these methods of operating a bandage should be applied to the limb and the patient kept in bed. Elastic stockings or rubber bandages should be worn after the patient assumes the erect posture. Intravenous injection of coagulating fluids, such as the iron salts, tan- nin and chloral, peri-vascular injections of ergotine, the application of caustic issues over the varix, and excision of portions of the dilated vein have been advocated. I reject them as probably more dangerous than subcutaneous ligation or acupressure. Patients with varicose veins, if debilitated, should be treated with tonics and made to refrain from occupations that require standing or other positions favoring venous stasis. Fluid extract of hamamelis has recently been recommended as an inter- mal remedy to be administered in fluidrachm doses several times daily. Its value, if it has any, is due to its astringent action. If hemorrhage occurs from varix, elevation and a moderate compress will stop it. Varicocele and internal hemorrhoids are instances of varix in special localities, which will be discussed in subsequent chapters. DISEASES OF LYMPHATICS. Wounds of Lymphatics. The lymphatic vessels of the body, which in their universal distribution exceed in number the blood vessels, are injured in all wounds. Lymph 248 D IS E A S E S OF LY M P H A TICS, escapes from the several vessels, but is mixed with blood, and demands no especial notice. It is only when the thoracic duct, a large lymphatic trunk, or a varicose lymphatic vessel is wounded that the escape of lymph is dignified by the name lymphorrhagia. The fluid thus discharged is at times transparent, at others milky in appearance, and may continue indefinitely if a fistula becomes established at the seat of injury. When a lymphatic vessel becomes occluded from pressure of a tumor or from disease, collateral lymphatic circulation is established, just as happens in veins. The lymphatic vessels and their valves much resemble veins as well in function as in histology. Lymphorrhagia is to be treated by pres- sure applied to the distal portion of the vessel, and lymphatic fistulas by compression and cauterization. Incision of lymphatic glands is said to have been followed by lymphatic fistulas. Inflammation of Lymphatic Vessels or Lynnphamgitis. PATHOLOGY..—Lymphangitis, or angeioleucitis, may be idiopathic, but generally it is traumatic. It should be remembered that though trau- matic in origin, it may first appear at a distance from the wound. It is especially liable to follow injuries inoculated with septic or other micro organisms. Simple lymphangitis is much less dangerous than the septic form, which frequently has a fatal issue. The pathological changes are similar to those found in phlebitis. The lymph loses its transparency, becomes opaque, and forms thrombi or, clots of a pinkish color in the vicinity of the valves. These clots, by adhering to the vessel wall may cause occlusion, or they may break down into pus. Thickening, opacity, and dilatation of the walls of the lymphatic vessels occur and the internal tunic becomes uneven. If occlusion is produced the ducts anastomosing with the obliterated vessel soon become distended and carry on the circulation of lymph. The connective tissue about the inflamed absorbents becomes infiltrated with lymph cells escaping from the vessels and peripheral oedema is induced by obstruction of the lymph current due to the internal thrombosis. The infiltrated structures may be relieved of this inundation by absorp- tive processes, may suppurate, or may become indurated and hypertro: phied. It is probable that occlusion of lymphatic vessels from repeated lymphangitis occurring in connection with cutaneous changes, is a factor in the causation of certain cases of Arabian elephantiasis. Cellulitis and arthritis may be secondary to lymphangitis, and even go on to suppura- tion. * SYMPTOMs.--Inflammation of the fine capillary absorbent vessels, which form an anastomosing network, is called reticular lymphangitis, while inflammation of the larger ducts is termed tubular lymphangitis. Reticu- lar lymphangitis occurs in patches, and may or may not be associated with inflammation of neighboring ducts of larger calibre. The adjacent glands, however, are nearly always involved. The patches are hot, red, painful, and surrounded by slight Cedema, and may go on to suppuration. Slight wounds, such as needle pricks, at the end of the finger, especially when infected with pathogenic bacteria and when in debilitated subjects; and frequent contact with septic tissues, even without breach of surface, may give rise to reticular absorbent inflammation, which may be mani- fested by multiple spots of inflammation successively extending up the limb. Certain forms of felon are instances of lymphangitis, and the skin ,” I N F L A M M ATION OF L Y M P HAT I C W E S S E L S. 249 disease called erythema nodosum is believed by some authorities to be a reticular lymphangitis, with lymphatic Oedema. Tubular lymphangitis, when affecting the superficial vessels, is mani- fested by the appearance of vivid red cutaneous lines running from the primary lesion toward the heart. These lines mark the centre of the inflamed ducts which, by palpation, can be felt as hard threads. There may be only slight tenderness along these red streaks, which by coales- cing make bands nearly an inch wide, but usually pain is marked and swelling of the limb observable. The nearest lymphatic glands soon become swollen and painful. Subsequently a second group of more dis- tant glands may be similarly involved, though there need not be any marked evidence of inflammation of the lymphatic vessels connecting the two glandular swellings. Resolution may occur in a week or ten days, though suppurative inflammation of the glands or of the vessels is not unusual. Glandular implication is almost never absent in lymphan- gitis. It is stated, however, that in septic inflammation of the lym- phatics such involvement may at times be wanting even when the syno- vial lymphatic structures show suppurative processes of great severity. The glandular inflammation or lymphadenitis results from the arrest of the causative bacteria in the sieve-like structure of the glands. When the deep lymphatics alone are inflamed the cutaneous redness is absent and the symptoms are obscure. Glandular implication is the only symptom which enables a diagnosis from cellulitis to be made. In lymphangitis the constitutional symptoms are rigors, high tempera- ture and other febrile manifestations, which in septic cases especially are accompanied by great prostration, delirium, and typical asthenic symptoms. Violent lymphangitis is often, probably always, due to the introduc- tion of putrefactive or other pathogenic bacteria into the lymph current, and is most liable to occur when open lymphatic capillaries are bathed in or subjected to the influence of septic fluids. It is developed not infre- quently in connection with dissection wounds, snake-bites, erysipelas, diphtheria, typhus and typhoid fevers, and the puerperal condition. Uterine lymphangitis of a septic character, which may follow labor even When no injury to mucous membrane has been inflicted, is very prone to cause diffuse peritonitis, and is usually fatal. Septic lymphangitis may arise, it would appear, without traumatism by an endosmosis of the poison through the skin. Patients in enfeebled health are more prone to septic lymphatic inflam- mation than those of greater resistive power. This form of lymphangitis may run an acute or a chronic course, and is the forerunner of general Septicæmic symptoms. Lymphangitis is to be diagnosticated from phlebitis by the higher febrile temperature of the former, the more vivid red of the cutaneous lines, and the associated glandular inflammation. In erysipelas the discoloration of skin is more diffused than in inflammation of the absorbent vessels. TREATMENT:-The treatment of lymphangitis is very similar to that *dapted to phlebitis. Septic infection is to be prevented by cleaning and thºroughly disinfecting wounds at the time of their reception. If the 9xistence of poisonous inoculation is suspected at the time, as is the case in, dissection wounds, suction and cauterization should be employed. Absolute cleanliness and antiseptics should be enforced on the part of those examining and attending puerperal cases, since septic uterime lymph- *gitis, is almost uniformly fatal. Local applications may be made along the course of the inflamed absorbent vessels when superficial. Moist 250 D IS E A SES OF L Y M P H A TI C S . antiseptic dressings, equal parts of extract of belladonna and glycerin, formentations containing morphia or other narcotics, and mercurial oint- ment have been recommended as topical measures. Pencilling with nitrate of silver and wrapping in dry cotton have advocates. The limb should be kept elevated and at rest. Free incisions to evacuate pus must be promptly made. Constitutional remedies of a supportive kind are always judicious. Quinine, iron and morphia, and often alcohol, are the drugs to be used. OEdema remaining after subsidence of the acute symptoms is to be treated by pressure with the elastic bandage, massage and passive motion of the joints. Lymphademitis. PATHOLOGY..—Inflammation of a lymphatic gland, called lymphade- mitis or simply adenitis, may occur without the existence of lymphangitis; but lymphangitis, as previously stated, rarely occurs without an accom- panying lymphademitis. The retentive or sieve-like function of the lymph- atic glands is the cause of their frequent implication secondary to inflammation of the lymph vessels. All material conveyed along any of these ducts is compelled to pass through the reticular or net-like structure of the corresponding glands. Here pigments from tattooing, septic par- ticles, whether bacteria or emboli, poison from syphilitic or other inocu- lated wounds, cells from malignant growths, pus and abnormal lymph cells are filtered out of the retarded lymph current and remain to choke up the network of small spaces and channels of which the glands are in large part formed. When these filtered-out particles cause stasis of the current, coagulation of lymph and inflammation of the gland structure, then lymphadenitis, with its characteristic swelling, hardness, and tender- mess, exists. * CAUSES.—Lymphadenitis then may be caused by direct irritation or injury to the gland or by any peripheral lesion or absorption that sends irritating substances to the gland. The lymph vessels between the periphery and the gland may be free from involvement, even though they have carried the irritative cause in the lymph current flowing through them. Lymphadenitis may be acute or chronic, and is due to infection by the tubercle bacillus, pyogenic organisms, and other bacteria, as well as to direct injury. The character of the inflammation depends on the cause and the constitution of the patient. SYMPTOMs.-The symptoms of acute suppurative lymphadenitis are swelling and tenderness of the gland, lancinating pain increased by motion, and fever. The connective tissue around the gland becomes implicated in the inflammatory process, the overlying skin assumes a red and glazed appearance, and suppuration begins in the centre of the gland or in the surrounding cellular tissue. Spontaneous evacuation of pus finally occurs through an irregular orifice surrounded by thin purplish skin, which after a prolonged period of cicatrization heals, leaving an ugly, puckered cicatrix adherent to the deep tissues. Cure by resolution without suppuration takes place in some instances of acute lymphadenitis, but it is so usually due to pus infection that the formation of pus is very common. Sometimes the tissues around the gland suppurate and on evacuation leave the inflamed gland exposed in the wound as a reddish- gray mass. Tubercular lymphadenitis, with burrowing of puriform fluid and the formation of sinuses, is not very infrequent. In some cases tubercular adenitis assumes a very chronic course, being accompanied by W A RIC O S E L Y M P HAT I C W E S S E L S. 251 * glandular swelling, induration, and hypertrophy without pain or fever or tendency to degenerative softening. In some regions of the body the lymphatic glands are scarcely perceptible by palpation through the skin until they become enlarged by inflammation, when the nodulation produced by them is sufficient evidence of adenitis. The inguinal bubo occurring after syphiliticinoculation affords a good example of the behavior of adenitis. If a whole group of glands is inflamed, the obstruction to lymphatic circulation causes oedema of the peripheral regions. This may become established if the adenitis is chronic. Septic lymphadenitis differs from simple acute lymphadenitis in its higher febrile movement and much greater danger to life. TREATMENT.-Acute lymphadenitis requires absolute rest of the part and antiseptic fomentations; blisters, or tincture of iodine painted around the inflamed gland may be serviceable. Pus should be evacuated by free incision, and the diseased gland and tissues removed by curetting. Car- bolized oxide of zinc ointment, iodoform, and similar applications will facilitate cicatrization of the resulting ulcer, which may become chronic and intractable. All sinuses should be laid open and scraped. Chronic adenitis with its characteristic hypertrophy is best treated by blisters, tincture of iodine, and firm pressure; the last agent may be applied by means of a specially adapted truss. Interstitial injections of alcohol by means of a hypodermic syringe will often cause absorption and diminution of large glandular masses. Caseous tubercular lymphatic glands should be enucleated, to prevent general infection of the patient; as should single groups of indurated glands producing deformity, such as occurs so frequently in the neck, if internal and local treatment does not dissipate the swelling. Chronic adenitis demands internal remedies, such as cod-liver oil and iodine. Syrup of the iodide of iron in full doses (mxxx-xl), quinine, iron, nutritious diet, and sea air are very beneficial, particularly in Strumous cases. Syphilis and malignant and other tumors may affect the lymphatic glands, but these topics demand no special consideration here. The pecu- liar disease variously called lymphadenoma, Hodgkin's disease, adeno- lympho-sarcoma, and malignant lymphoma, which is attended by enlarge- ment of many groups of glands and profound anaemia, is a medical rather than a surgical affection. Varicose Lymphatic Vessels. Varicosity, or dilatation of the lymphatic networks gives rise to small transparent vesicles, like boiled sago grains, which are more frequently seen upon the inside of the thigh, and upon the genitals and the abdomen than elsewhere. When the superficial lymphatic trunks are the subject of this infrequent condition, the dilated portions give rise to larger and more elongated swellings. . There is usually odema of the peripheral parts. Lymphatic varicosi- ties can readily be emptied of their fluid contents by pressure. Arabian elephantiasis is at times complicated with lymphatic varicosity. Systic dilatation of the lymphatic ducts occurs at times in the tongue, lips, and neck. . A tumor formed of a congeries of dilated lymphatic vessels and similar in structure to the arterial and venous vascular tumor, or angioma, is occasionally developed. It is appropriately called a lymphangioma. 252 IN J U R I E S A N ID DIS E A S E S OF A R T E R I E.S. Rupture or wound of a dilated lymphatic vessel is liable to be followed by lymphorrhagia, or a prolonged discharge of lymph. If a fistula result, cauterization and pressure are proper. Lymphatic dilatation usually needs no treatment. The methods adopted in corresponding venous changes would be applicable. INJURIES AND DISEASES OF ARTERIES. Wounds of Arteries. PATHOLOGY..—After contusion of arterial coats there is a liability to ulceration and secondary hemorrhage, which occurrence will, in open wounds, demand prompt ligation at both sides of the bleeding orifice. If the contusion has occurred subcutaneously, the ulcerative action will allow extravasation into the muscular and cellular tissues, which, if ex- tensive, may call for incision into the tissues and ligation of the vessel at both sides of the wound, for ligation above the seat of injury, or for amputation of the limb. ,” By the advent of inflammation or thrombosis, a bruised artery at times becomes obliterated at the seat of contusion, and this occlusion may give rise to gangrene or visceral degeneration. Aneurism also may be de- veloped after contusion of an artery. Slight contusions of arteries may occur without marked pathological consequences. The elasticity of the vessels, and their relations to sur- rounding parts often protect them from such violence. Arteries may be torn completely asunder subcutaneously by violent manipulation, as in reducing old dislocations, or by accidental injuries. The extravasation which follows may be absorbed as the torn ends of the artery become sealed by obliterative inflammation, or it may become sur- rounded by a capsule or sac, consisting of cellular tissue thickened and condensed by pressure and inflammation. The extensive character of the subcutaneous bleeding may cause violent inflammation, and its inter- ference with the peripheral circulation may, because of pressure, lead to gangrene. Amputation is at times demanded for such sequences of arterial rupture. Subcutaneous extravasation of blood, from spontaneous or traumatic rupture or direct wound of an artery, is sometimes termed “aneurism.” The term, even though qualified by the words false or traumatic, should be rejected, as it is misleading as well as unscientific. When the effused blood becomes encapsulated and the communication with the artery per- sists, the resemblance to aneurism is, however, great. Then the term is not altogether inapplicable, though the condition is not strictly an aneurism but an arterial haematoma. Complete laceration, or tearing asunder, of an artery in an open wound may be unattended by hemorrhage because of the twisting and tearing of the coats at the time of injury. It is well, however, to ligate such vessels before the first dressing is applied if they are seen pulsating in the wound. The two inner coats of an artery are sometimes torn in subcu- taneous injuries, while the external tunic by reason of its elasticity re- mains intact. This partial rupture may subsequently become complete by the giving way of the outer coat, and be followed by fatal extravasa- tion. On the other hand, the torn coats may curl up, cause coagulation within the vessel, and thus lead to permanent occlusion, or to arrest of W O U N DS OF A R T E R IF. S. 253 circulation and consequent gangrene. Gangrene may arise also from the torn shreds acting as a valve and at once shutting off the blood-flow to the parts beyond. Sometimes the injured region remains as a weak spot or cicatrix which finally becomes the seat of aneurism due to a traumatic Call Se.

Wounds of arteries, inflicted by sharp instruments or spiculas of bone, may, under rare circumstances, involve only the outer and part of the thickness of the middle coats. Such non-penetrating wounds give rise to no primary bleeding, but almost invariably are followed in a few days by secondary hemorrhage. Hence, partial penetration of arterial walls, when recognized, should be treated by exposure of the vessel, ligation on both sides of the wound, and complete section of the artery between the ligatures. Penetrating arterial wounds, unless inflicted by very fine needles, are followed by hemorrhage, either at once or secondarily from ulceration. The amount of primary bleeding from incisions into arteries depends on the direction as well as the size of the wound. Transverse wounds allow more gaping and, therefore, more bleeding than longitudinal inci- sions. Oblique cuts hold an intermediate position. Complete section of an artery is less dangerous in this respect than an incision involving only a portion of the circumference, for the former, by allowing contraction and retraction of the coats, affords an opportunity for spontaneous arrest of bleeding. This is the reason that when cessation of bleeding is desired after arteriotomy of the temporal artery for therapeutic objects, the surgeon completely divides the vessel. Bleeding may at once cease after the division, though pressure is often needed in addition. If this section, moreover, was not done, secondary hemorrhage or traumatic aneurism might occur. Arterial wounds may be followed by death from external or internal hemorrhage, or may cause suppuration or gangrene secondary to burrow- ing of the extravasated blood in the cellular tissue. The tissues may cicatrize and traumatic aneurism may be developed as a result of arterial injury. If the corresponding vein is wounded arterio-venous fistula may develop. TREATMENT.-The treatment of arterial wounds in the limbs should begin by resort to temporary compression by means of a rubber bandage tightly applied above the wound. The arrest of bleeding thus obtained allows opportunity for enlarging the wound in the superjacent structures, which should be followed by ligation of the vessel on both sides of the Wound, and by complete division of the artery at the point of injury. Two ligations are necessary in all such cases, because establishment of the 254 IN J U RIES A N D DIS E A SES OF A R T E R IE S. collateral circulation will render secondary hemorrhage from the distal part of the artery almost certain. Gunshot wounds of arteries require similar treatment. When the arterial lesion is subcutaneous, or the communication with the air valvular, or when the superficial tissues have healed before the partially divided vessel has given way, large extravasation and burrowing of blood may occur. The symptoms are: Sudden prostration and syncope from the anaemia, and the development of a soft, somewhat elastic and fluctuating tumor, with, perhaps, an impulse, thrill, and bruit similar to what is found in an aneurism. Pulsation in the peripheral vessels may become absent and the limb oadematous and of low temperature. Pulsa- tion will probably not appear in the tumor until the formation of a cir- cumscribing cyst wall has begun. This diffuse extravasation may con- tinue increasing until death results or gangrene occurs. Death may supervene by rupture and a discharge of blood and clots into some cavity, or from the skin giving way, through suppuration and ulceration, and allowing secondary hemorrhage. The treatment of such cases of arterial injury consists in applying pressure to the artery above the wound and over the swelling, keeping the patient in bed and the limb at absolute rest by bandages and splints. The rubber bandage of Esmarch may be used temporarily to occlude the artery. Ligation of the trunk at some distance above the swelling so as to be above the first branch will generally succeed if these measures be inefficient. When it is impossible to obtain absolute rest, or when ligation above the first collateral branch is inapplicable or inefficient, pressure by a rubber bandage above the wound must be made or artificial anaemia by the Esmarch method obtained, the tumor laid open, the clots turned out, the artery completely divided, and both ends secured by catgut ligatures. The easiest way to isolate the artery is to insert a probe into the opening and then dissect the vessel free. The ligature can then be readily passed around it by means of a curved needle with an eye near the point, or by Horner's curved awl, which has a shoulder to carry a loop of string through the tissues and around the vessel. If the circulation cannot be controlled above by the Esmarch IIorner’s awl. apparatus, the surgeon must make a small opening in the skin and intro- duce one or two fingers of the left hand into the cavity of the tumor. Thus he prevents profuse external bleeding by having the cutaneous wound plugged with the fingers with which he feels for and compresses the arterial wound. After getting the opening in the artery closed by digital pressure, he uses the right hand to enlarge the skin wound and then proceeds to turn out clots and ligate. In military surgery and in special cases amputation may be preferable to these procedures. When the extravasation is comparatively small and has become circum- scribed by an adventitious sac of condensed and thickened connective tissue, laying open the cyst wall and tying both ends of the artery will often be quite easily performed, and, being the radical operation, is prob- T R A U M ATIC A.N E U R IS M . 255 ably more judicious than ligation of the artery above the tumor. In the diffuse and profuse extravasations just discussed, ligation above the first branch is probably more judicious than searching for the arterial wound among the structures inundated with partially coagulated blood, and is certainly better than ligation immediately above the injured part of the artery. This position of the ligature is usually allowable only in the small extravasations, where there is little danger of secondary hemorrhage from the distal part of the vessel when the collateral circulation is established. Surgical interference should not be adopted too hastily in small arterial extravasations, especially when they are subcutaneous or due to fractured bones injuring the artery. Spontaneous cure may be accompanied by the contraction of the con- densed cellular tissue and coagulation of the blood. The encysting pro- cess, which causes the development of an adventitious sac, is the first step in such cases. Hence, the surgeon should, when possible, wait until he has decided that nature's efforts at cure are ineffectual. Traumatic Aneurism. VARIETIES.–Traumatic aneurism is a secondary result that occasionally follows arterial injuries. This term has often been improperly applied. It should be restricted to the following conditions: 1. Dilatation of the cicatricial tissue and adjacent arterial wall after a healed penetrating wound of an artery. 2. Dilatation and hermial protrusion of the uninjured inner coats through a wound of the outer tissue alone. 3. Dilatation of the outer tunic after an injury producing rupture of the inner coats alone. Such ruptures are, as a rule, produced only in vessels whose inner coats have been weakened by degenerative changes, such as atheroma. Hence, such cases have an origin which often makes the terms spontaneous aneurism and traumatic aneurism equally inappro- priate, since two causative elements are present. In many of these cases it is impossible to arrive at the exact cause, from either the clinical history or symptoms. Fortunately, these are the very instances in which treat- ment is very little influenced by the character of the cause. A limited extravasation of blood from puncture of one of the smaller arteries may become surrounded by an adventitious sac, formed by inflam- matory condensation and thickening of the normal areolar tissue. This differs somewhat from the diffuse and burrowing extravasation spoken of on a previous page under wounds of arteries, and has more right to the title “traumatic aneurism.” Still it is not strictly an aneurism, though it is a blood tumor which pulsates and has a thrill and bruit. It is nothing but an encysted extravasation of blood; or, in other words, an arterial haematoma. An aneurism is a circumscribed dilatation of one or more of the arterial coats, induced by the distending influence of the blood current upon abnormal vascular walls. The condition being discussed having no such pathological nature, should not be called an aneurism. To call it a “false ’’ aneurism would be illogical, since what is a false aneurism is evidently no aneurism. TREATMENT.-The proper treatment of traumatic aneurism is compres- sion of the artery as near as possible to the sac ; or, in the event of this procedure failing, ligation in the same situation. 256 A R T E RIO – W E N O U S W O U N ID S A N D FIST U L E S. Small or superficial traumatic aneurisms may be treated by incision of the sac and ligation of the artery on both sides of it. Dissection of the tissues so as to expose the sac and the artery, followed by ligation on both sides without opening the sac, is a good modification of the same method. The different methods of ligation, described in the section on the treat- ment of spontaneous aneurism as Hunter's, Wardrop's, and Brasdor's methods may sometimes, on account of the location of the tumor, be preferable to ligation immediately above the sac. ARTERIO-VENOUs Woun DS AND FISTULEs. DEFINITION AND PATHOLOGY..—Puncture or gunshot wounds simul- taneously penetrating an artery and an adjacent vein are liable to be followed by a persistent orifice of communication between the two blood- vessels. Such fistulous communications which may form slowly have been improperly called arterio-venous aneurisms. When the lips of the arterial wound remain in contact with and become closely adherent to those of the adjacent vein, a direct fistulous opening is established between the calibre of the artery and that of the vein. When the wall of the vein is pushed away from the wall of the artery and the extravasated blood burrows between them, a pouch or sac is developed, which communicates on one side with the artery and on the other side with the vein. The former condition has been termed aneurismal varix; the latter varicose aneurism. Neither of them is an aneurism, for they FIG. 100. FIG, 101. First form of arterio-venous fistule. Second form of arterio-venous fistule. (WYETH.) (WYETH.) are not circumscribed dilatations of one or more of the arterial coats induced by the distending influence of the blood current upon abnormal vascular walls, Hence, to class them together under the general heading arterio-venous aneurism is obviously improper. The first form is exhibited as a varicose vein or varix, with pulsation; and, therefore, may, per- haps with some degree of propriety, be called an aneurismal, or better, an aneurismoid varix. The second form is in the development of its adven- titious sac identical with the encysted extravasation of arterial hematoma described on page 252, which I there said was improperly termed a trau- matic aneurism. Hence, it has somewhat more right to be classed with aneurisms than the first form. I prefer to use the terms simple arterio- venous fistule, and sacculated arterio-venous fistule to describe the two forms of preternatural arterio-venous communication. Arterio-venous fistules of both kinds very occasionally arise without traumatism. Ulceration or an abscess may open a contiguous artery and vein and permit the establishment of a direct or indirect orifice of com- munication. Again, a true aneurism may cause thinning and perfora- tion of a vein upon which its sac presses. In this case, however, the SI M P L E A R T E R I O - W E N O U S FIST U L E . 257 condition is a sequence and complication of aneurism, not a new disease deserving a special name. Simple Arterio-venous Fistule or Aneurismoid Varia. SYMPTOMs.-Aneurismoid varix is a dilated condition of a vein due to a direct fistulous aperture between it and an artery. It appears as a small, soft, bluish tumor, readily disappearing on pressure, which is the seat of a peculiar tremulous jarring or vibratory pulsation, and a charac- teristic continuous but remittent purring murmur. The vibration and murmur are due to the injection of a small stream of arterial blood into the vein through a narrow orifice at each pulsation of the artery. This forcible blood current, by greatly increasing the intravenous pressure opposite the orifice of communication and by antagonizing the upward flow of venous blood, causes marked distention of the vein at the site of the fistule, and leads to varicosity of other veins in the vicinity. The vibration and murmur may be transmitted along the veins to a considerable distance from the opening; especially is this the case in an upward direction. The swelling, vibration, and murmur are lessened by elevation of the limb, increased by its being placed in a dependent posi- tion. Digital compression of the vein at the cardiac side of the tumor increases these phenomena, but similar compression on the distal side exerts no influence whatever. Compression of the artery above the swelling causes immediate arrest of vibration and murmur, which are at once reëstablished upon removal of pressure. Pressure upon the artery below may be expected to increase the size of the swelling. The arterial trunk above the seat of disease may after a time become enlarged and pulsate more vigorously than the corresponding vessel of the opposite limb; but below the aneurismoid varix the artery and its branches become smaller and show diminution of the normal pulsation. The limb below the disease is usually weak and of lower temperature than normal. It may exhibit a hypertrophic condition of the skin, mails, and hair, and become the seat of Oedema, ulceration, hemorrhage, and perhaps gangrene. These secondary changes are due to interference with the normal circulation. Aneurismoid varix of the scalp is sometimes followed by such a gen- eral hypertrophy of the venous and arterial branches that a mass of con- Voluted and pulsating vessels is formed which cannot be distinguished from arterial varix, the so called cirsoid aneurism. , Simple arterio-venous fistule or aneurismoid varix is usually an affec- tion of slow progress. If it does not increase nor annoy by reason of its bulk or murmur, it requires no treatment. After arterio-venous punctures, which by the way have not infrequently been received during venesection at the elbow, the possible occurrence of fistule should be remembered and an attempt to prevent such a sequence should be made by applying pressure to the wound and also to the artery above the injury. TREATMENT—If curative treatment is deemed necessary, continuous digital pressure upon the tumor directly over the orifice should be made. The use of the rubber bandage may be advantageous if so applied as to stop the circulation through the limb, and yet leave the tumor filled With, blood. Coagulation and consequent occlusion of the orifice may Possibly be thus effected. Many cases will resist both of these plans of 17 258 A R T E R I O – W E N O U S W O U NI) S A N D FIST U L E S. treatment. Then resort to ligation is justifiable in severe cases of the disease. The artery should be tied above and below the opening with catgut. The vein should be carefully separated from the artery at the point of ligation and left unmolested, since its ligation or destruction greatly increases the risk of gangrene of the already poorly nourished limb. In such a locality as the thigh, where the integrity of the femoral vein is so essential, it is better to omit placing the lower ligature on the artery and trust to elevation of the limb rather than to endanger the vein by rudely endeavoring to separate it from the artery. It sometimes requires great care during the operation to distinguish the thickened and pulsating veins from the artery. Sacculated Arterio-venous Fistule. The so-called varicose aneurism is not an aneurism, but is a sacculated arterio-venous fistule, differing from the aneurismoid varix or simple arterio-venous fistule in having a sac or pouch between the artery and vein, from which there is one opening into the artery and another into the vein. In this sac, which is due to inflammatory condensation and thickening of the normal connective tissue, the arterial and venous blood currents meet and intermingle. FIG. I.02. Sacculated arterio-venous fistule. (ERICHSEN.) SYMPTOMs.-Theclinical history differs from that of simple arterio-venous fistule or aneurismoid varix in having certain additional symptoms. The same venous varicosity exists and the same vibratory or jarring motion, and purring murmur are present in the veins, though less marked than in aneurismoid varix, because the arterial stream is not forced directly into the vein. A tumor more or less solid can often be perceived lying between the two vessels. This is felt to be the seat of a pulsation synchronous with the arterial pulsation and distinct from the tremulous jarring of the dis- tended vein. Auscultation reveals a blowing murmur, like that of a true aneurism which is additional to the purring murmur, due to the blood entering the vein. CEdema, cutaneous hypertrophy, ulceration, and other nutritive changes may occur, as in aneurismoid varix. The sacculated arterio-venous fistule differs from the simple in its greater tendency to be progressive; and, by the distention and enlargement of the sac, to lead to sloughing of the skin and fatal hemorrhage. The sac, as a rule, grad- ually becomes somewhat hard from internal fibrous deposition, and, indeed, this process occasionally causes spontaneous closure of the venous open- ings and simplifies the treatment of the disease. The progressive char- acter of the condition is such that treatment is nearly always demanded. TREATMENT.-Means to obliterate the sac should usually be under- IN F L A M M A TO R Y C H A N G E S IN A R T E R IF. S. 259 taken if the diagnosis from aneurismoid varix has been established. This differential diagnosis at times may be difficult. Digital or instrumental compression of the artery above the disease, combined with pressure di- rectly upon the opening into the vein, should be the first resort. A similar method is to apply the rubber bandage tightly from the fingers or toes up to the tumor, to carry it with only moderate pressure over the tumor and finally to constrict the limb tightly above the seat of the disease. Thus the sac is left full of blood which, by the arrest of circulatory movement, is given an opportunity to coagulate and thus induce oblitera- tion of the sac and closure of the fistulous apertures. Pressure, if it does not cause a radical cure, may at least close the venous opening and thus reduce the lesion to a more simple and manageable condition. When pressure fails, ligation of the artery immediately above and below the sac is the proper procedure. The coats are usually healthy, since the condition is due in nearly every instance to a wound. Hence, the ligatures can be applied near the seat of disease. The neck of the sac also, if accessible, may be tied close to the artery. When the shrunken lower part of the artery cannot be found, it may become necessary to lay open the sac. A probe can then usually be passed down the vessel through the aperture connecting the sac with the calibre of the artery. In such operations it must be remembered that if the vein is first laid open, the surgeon sees only the venous opening into the sac. A second incision is then required to open the Sac and disclose the arterial orifice. Care should be exercised to avoid tying or tearing the main veins of the limb. Such a complication adds to the risk of gangrene. When such venous inter- ference is unavoidable in old and feeble patients, amputation will prob- ably be preferable to the double ligation. In all these operations the rubber bandage should be applied as a preparatory step. Coagulating injections into the Sac after immobilizing the blood by an elastic bandage have been suggested. The method by ligation is prob- ably less dangerous, and at the same time more radical in principle. ARTERITIS AND DEGENERATIVE CHANGES IN ARTERIES. PATHOLOGY..—Inflammation of arterial walls, if acute, usually involves, Sooner or later, the three coats; but the pathological changes may begin or become more marked in any one of the tunics. Hence, we have the terms endarteritis, mesarteritis, and periarteritis expressing inflammation of the imper, middle, and outer coats respectively. Chronic arteritis affects principally the inner coat. Arteritis is caused by external or in- ternal violence, such as wounds or lodgement of emboli; by extension of inflammation from surrounding tissues, as in phagedena; and by the con- stitutional states that induce impaired nutrition, such as syphilis, rheum- atism, gout, alcoholism, and renal disease. The results that may follow arteritis are fatty degeneration, atheroma, and calcification of the tunics; occlusion or aneurismal dilatation of the calibre of the vessel; and sup- puration, ulceration, or perforation of the vascular wall. The organs and structures supplied by the inflamed artery may suffer by loss of func- tion and become the seat of gangrene secondarily to these sequences of arteritis. The pathological changes found in traumatic arteritis are similar in character, whether they begin externally or internally. The inflammatory process commences in the tunic injured, but, as a rule, soon spreads to the 26() I N F L A M M ATION OF A R T E R IE S. other coats. Internal violence, such as is produced by the impinging of the blood-current or by the impact of an embolus, is more apt to induce an inflammation limited to one tunic than is external violence, which usually injures all coats simultaneously. Traumatic arteritis from external causes must necessarily be accom- panied by contusion, laceration, or some such complicating lesion of the periarterial structures. * * The pathological, alterations seen in arteritis are very like those which have been detailed as occurring in phlebitis. The external tunic of the artery becomes unusually vascular, and is swollen from infiltration by serum and white corpuscles that have migrated out of the vasa vasorum. These changes cause thickening and softening. The middle and internal coats also are thickened and softened and the site of cell proliferation. The internal tunic loses its smooth, glistening appearance, is elevated in patches which are sometimes the seat of erosions, and usually becomes pinkish in color. The calibre, or lumen, of the vessel is lessened by the swelling of the coats, the projection inward of the inner tunic, and prob- ably also by spasm of the inner coat. When there is rupture of the in- ternal tunic, as happens in ligations and other injuries, there will be more encroachment and even occlusion of the lumen, for the roughened and projecting margins will cause fibrinous deposition. The formation of a coagulum consisting of white corpuscles and fibrin occurs in arteritis as in phlebitis, though less often, even without previous rupture of the inner coat. It is much more unusual in acute than in chronic arteritis. In syphilitic arteritis it is not infrequent. As in phlebitis the thrombosis is at times the cause, at others the result, of arteritis. When complete occlusion of the artery and arrest of the blood-current are produced by the pushing inward of the internal coat and by the depo- sition of cells and fibrin, permanent obliteration of the vessel may take place from organization of the cells of the coagulum as was formerly believed, or from organization of the newly-formed tissue springing from the normal cells of the internal coat. There occurs thus a species of cicatricial contraction which converts the former arterial tube into an impervious, fibrous cord. Sometimes, however, the clot, on the other hand undergoing fatty degeneration, is washed away as minute particles of fat which do no harm, and the artery regains its normal patulous con- dition. Sometimes fragments of the clot are detached, and as emboli are carried onward until they plug some distant artery of smaller calibre. There they may be absorbed or may produce local anaemia and infarction. At other times disintegration of the primary coagulum occurs, due to septic or pyogenic bacteria, and septicaemia or multiple infective embolism and pyaemia may result. When suppuration and ulceration occur, as happens at times in Septic traumatic arteritis, there is great liability of perforation and hemorrhage unless the previous occlusion of the artery by a coagulum has been com- plete. Suppuration in the outer coat is generally diffuse, but in the middle tissue it may be localized as distinct abscesses. Pyaemic infarction is readily induced if septic material from suppuration of the vascular walls or of the surrounding structures gains entrance to the blood current. The hyperplasia of connective tissue, which may take place in the middle coat as a sequence of arteritis, causes atrophy of the muscular and elastic fibres, and renders the vessel less able to resist the distending influence of blood pressure; hence, subsequent aneurismal dilatation may occur at the seat of the former arterial inflammation. Infective emboli, causing acute D E G E N E H A TI W E C H A N G E S IN A R T E RIE S. 261 inflammation and softening, are believed to be a frequent cause of aneurism when occurring in the young. Idiopathic arteritis is usually associated with and a result of inflammation of the structures surrounding the vessel, unless it be due to syphilis, gout, or some similar dyscrasia. Many cases denominated idiopathic arteritis are really instances of traumatic inflammation, caused by the impact of the blood current, or of emboli from cardiac vegetations against the internal arterial coat. Such are the cases of endarteritis and resulting fatty degen- eration not infrequently found at the great sinus, the transverse arch and the bifurcation of the aorta, and in the innominate artery. Idiopathic arteritis presents pathological changes similar to those seen in traumatic C2SéS. Syphilitic arteritis is a chronic inflammation, and occurs especially in the smaller arteries. The vessels of the brain are particularly liable to it, and on account of the resulting circulatory interference the disease is a serious one in this locality. Aneurism may be due to syphilitic arteritis of the aorta and larger vessels. The pathological changes arise chiefly in the internal tunic, which by reason of the inflammatory proliferation of cells projects into the lumen or calibre of the vessel, and causes great nar- rowing or complete occlusion of the blood channel. Death from cerebral anaemia thus induced is not very infrequent. It is often impossible dur- ing life to diagnosticate syphilitic arteritis from atheroma. In fact, both diseases may exist at the same time. Atheroma is more common in the old than the young, and causes arterial weakening and dilatation rather than occlusion. Atheroma is not so apt to attack the smaller vessels as is syphilis. After death microscopic examination shows that atheroma has a greater tendency to involve all the coats than syphilis, which is usually more or less limited to the internal coat. Rheumatic arteritis is said to be rare. That it has not been studied as carefully as the other forms may be the reason for this supposition. Rheumatic inflammation of the lining membrane of the heart, which is similar to the lining coat of arteries, is certainly common. Mechanical strain put upon the coats of the vessel by reason of increased or unusual intravascular pressure is a cause of chronic arteritis. These chronic forms of arteritis are all allied to degenerative processes, and have few well- marked symptoms. SYMPTOMS.—The symptoms of arteritis, when more or less acute, and the accompanying thrombosis are severe pain, tenderness and hyper- *sthesia in the course of the vessel and in the parts supplied by it, and impairment of muscular power. This pain may resemble rheumatism. The surface temperature is lowered, and the skin perhaps mottled. When the vessel is superficial, a hard, pulseless cord may be felt or seen through the skin ; if only partial occlusion has taken place, a jerky pulse may be berceptible. Secondary gangrene, with its characteristic symptoms, may arise from the interruption of circulation, especially in the old and feeble. TREATMENT.-The treatment of arteritis consists in rest, wrapping up the limb in cotton to maintain heat, administering opium to relieve pain, and using tonics, stimulants, and good food to prevent depression. As gangrene is a not unusual sequence, the husbanding of vital resources is required. This precludes the use of depressants in the early stages, unless the patient is unusually vigorous and the disease so situated as to render subsequent gangrene limited. Measures to obviate gangrene and to avert fatal hemorrhage from ulcerative perforation are to receive careful consideration. Syphilitic, rheumatic, gouty, and other forms of arteritis 262 I) IS E A SES OF T H E A R T E R [E S. should be treated with mercury, iodide of potassium, alkalies, salicylic acid, colchicum, etc., with a view both of preventing further progress and of perhaps effecting cure. Microbic invasion of wounds must be pre- vented by rigid asepsis and antisepsis, since it has been shown that septic discharges are the chief cause of ulcerative and suppurative arteritis. ATHEROMATOUS DEGENERATION AND CALCIFICATION OF ARTERIES. Any form of chronic arteritis may terminate in atheromatous degenera- tion of the vascular walls. This condition is due to malnutrition of the arterial tunics, and is a fatty degeneration of their cellular elements. It occurs as a secondary lesion following chronic inflammation of arteries, and is frequently found in syphilitic and senile subjects. It differs from the primary and localized fatty change belonging to the pathology of endarteritis in being a secondary lesion, which affects the arteries gen- erally, and which is liable to give rise to thrombosis, embolism, and hemorrhage. The destructive process, moreover, causes infiltration not only of the inner coat, but also of the muscular and elastic coats, trans- forming the normal elements into granular material. Atheromatous degeneration is seen, on examination of the inner surface of the vessel wall, as numerous definitely-outlined, soft, pulpy patches, which are scat- tered throughout the arterial system. The pulpy material found in the centre of these softened spots gives the name atheroma to this peculiar molecular destruction, and under the microscope is found to consist of fatty and granular matter, mingled with cholesterin crystals and shreds of fibrous tissue. The middle coat soon becomes infiltrated with fatty particles, and the outer one also undergoes degeneration. The weakening of the vascular wall may allow the blood pressure to cause aneurismal dilatation or rupture. The softening of the deep layers of the internal coat may give rise to the so-called atheromatous abscess; if the Superficial layer is destroyed the atheromatous ulcer remains. At times calcereous degeneration of the tunics occurs as a secondary and conservative process, as if nature was endeavoring to counteract the effect of the softening influences of atheroma. Calcification is more fre- quent when the atheromatous change is slowly progressing, and the two processes may be going on together at the same time in the same locality. The chalky change begins in the inner and middle coats, but the entire vessel wall may be converted into a calcareous cylinder, though isolated plates of calcification are much more common. By the washing away of the pulpy or atheromatous material on the inner surface the calcareous plates may be uncovered; and sometimes the blood current gains entrance beneath the chalky portion of the wall, and by a species of dissection separates the tunics, or their different layers, and thus creates the so-called aneurism by dissection. The atheromatous and calcific degeneration causes arteries to become brittle and inelastic and roughened on the interior and exterior, and thus predisposes to loss of function and rupture, by which hemorrhage, occlu- sion, and gangrene may arise. It is a common senile change, and is par- ticularly liable to occur in the arteries of the brain and in the main arteries of the trunk and limbs. It is not uncommon as a ring about the root of a large branch. Ligation of such diseased vessels is apt to be followed by secondary hemorrhage from the ligature cutting through the brittle walls. A broad, flat ligature to produce mere apposition of the A N E U R IS M . 263 arterial walls is proper under such circumstances. The weakening of the middle coat induced by atheroma is a frequent precursor of spontaneous aneurism. Some writers believe that the calcareous degeneration of arteries in the aged is not secondary to atheroma, but is a primary change, and occurs in the middle coat first ; while that secondary to atheroma begins in the internal coat. True ossification of arteries seldom, if ever, occurs. Cases so denomi- nated are probably instances of calcification. These degenerative changes cannot be arrested by any special line of treatment. The indications are to keep up nutrition, to avoid severe exercise, which causes increased blood pressure in the brittle arteries, and to perform none but necessary operations, because of the imperfect circulatory supply and the tendency to secondary hemorrhage. ANEURISM. DEFINITION.—An aneurism, strictly defined, is a circumscribed dilata- tion of one or more of the arterial coats, induced by the distending in- fluence of the blood current upon abnormal vascular walls. This definition properly excludes: 1. General dilatation with elongation of an artery (often called cirsoid aneurism, varicose artery, arterial varix). 2. General dilatation of small arteries and of capillaries (often called aneurism by amastomosis). 3. Arterial venous fistule (usually called arterio-venous aneurism). 4. Separation of the arterial tunics by the blood current (usually called dissecting aneurism). 5. Extravasation of arterial blood due to spontaneous rupture (one of the forms of so-called false aneurism). 6. Extravasation of arterial blood due to wounds and injuries (called by some writers a form of traumatic aneurism). These widely different pathological conditions often receive, though improperly, the name aneurism because they are tumors containing blood or blood-clots. They are not aneurisms according to the definition that I have given, and as they present symptoms and require treatment different º aneurism I have discussed them in their appropriate places else- Where. VARIETIES.–If the conditions mentioned above be excepted, there are only two forms of aneurism—the tubular or fusiform and the sacculated Or Sacciform. Separation of arterial coats, which occurs at times as a result of arter- itis by the blood insinuating itself between the layers of the middle tunic or between the inner tunic and the middle, is, under the name “dissect- ing” aneurism accepted by most writers as a form of aneurism. I prefer, however, to reject it, since it differs from aneurism in every essen- tial feature. It occurs chiefly in the aorta, which may show the separation through nearly its entire length. The blood current may separate the Coats for a long distance or form a circumscribed sac within the thick- ness of the arterial wall. The blood may finally burst through the outer surface of the wall, and cause hemorrhage into the cellular tissue, or into the pericardial, pleural, or abdominal cavity. Sometimes the diverted Current re-enters the calibre of the vessel through an opening, due, as Was the opening of exit, to a patch of atheromatous softening. This tun- 264 D IS E A SES OF T H E A R T E R IES. nel-like channel, with the consequent thickening of the vessel wall, may cause the artery to present the appearance of being double. It would be possible for the separated coats to bulge into the calibre of the artery, and by occlusion cause gangrene of the parts FIG. 103. below. It is readily seen that this separa- tion of arterial coats is very different from aneurism, and only corresponds to the defi- nition of aneurism when a distinct circum- scribed sac is formed within the thickness of the vessel wall. This is of exceedingly rare occurrence. It is, therefore, better to limit the term aneurism to the two forms, tubular and sacciform, and dismiss the term dissecting aneurism entirely, using instead the words separation of arterial coats. A fusiform or spindle-shaped aneurism is a dilatation or expansion of the entire cir- - cumference, and usually of all the coats of º W an artery, while a sacciform aneurism is a º Yº sac or pouch consisting of one or more of à º the coats developed upon one side of the artery, and communicating with the interior of the vessel by a narrow opening. Fusiform aneurism is much less common than the sacciform variety, and is chiefly à| ºi à à s º i‘. º | i 2. § 2-:* : à | º º º: É : i : § | º 2. à | | # º à # º # .* i * § % # à% : 2. : 3. iº # met with in the aorta, and in the iliac and º femoral arteries. The dilatation, though - not always uniform, is usually more marked Diagram showing separation at the middle of the tumor and diminished of arterial coats, often called dis toward each extremity until the normal secting aneurism. calibre of the artery is regained. This gives * the aneurism, which necessarily has an opening of entrance and one of exit, a spindle shape. The walls of the tumor consist of degenerated and thickened arterial coats with a rough- ened inner surface. There is some increase in the length of the artery at the dilated and hypertrophied spot. This form of aneurism, unlike the sacciform variety, does not, as a rule, enclose laminated fibrine. Chronic arteritis with its consequent atheromatous degeneration of the arterial walls is the chief factor in the causation of such aneurisms. Traumatic fusiform aneurism seems to me to be almost an impossibility. Occasionally several fusiform aneurisms are developed in connection with the same artery, which is of normal calibre between the dilated regions. The lateral blood pressure in fusiform aneurisms is comparatively mod- erate in amount; hence they grow slowly and do not readily burst; but it is not unusual for a sacciform aneurism to be developed upon the sur- face of a fusiform dilatation and to cause death by rupture. In cases of very large fusiform aneurism of the aorta death may also occur from syncope, because the heart is unable to give sufficient forward motion to the mass of blood contained in the large tumor. Hence the circulatory movement in the more distant vessels is impaired and fatal syncope may supervene. The sacciform aneurism is the most common variety of the disease, and is that which is meant when the simple term “aneurism " is used. Fusi- form aneurisms are so infrequent, and in comparison with the sacciform A N E U R IS M . 265 variety so unimportant surgically, that I shall scarcely refer to them again. My subsequent remarks, therefore, will refer to sacciform dilata- tion of arteries. A sacciform aneurism is a sac or pouch developed upon one side of an artery by localized dilatation of the arterial wall and communicating with the interior of the vessel by a narrow orifice or mouth. The cavity of the sac has a much greater diameter than its orifice of communication with the artery, and it is, therefore, usual to speak of the body, neck, and mouth of the aneurism. The walls of the sac may, if the tumor is small, consist of all three arterial tunics; but usually it is only the outer tunic, and perhaps part of the thickness of the middle tunic that form the sac. As internal pressure causes further distention, the tunics become blended and finally may disappear at places and be substituted by an adventitious wall of condensed and newly-formed cellular tissue. Sacciform aneurism may be developed upon the sur- FIG. I ()4. face of a fusiform aneurism, which is, as has been Seen, little more than a diseased and greatly enlarged ar- tery. CAUSES.—Any agency that lessens the power of the arterial wall to resist the stretching influence of the blood impelled by the cardiac impulse, and any circumstance that diminishes that normal elasticity by which the artery contracts as soon as this stretching influence is relaxed must predispose to aneurismal dilatation. Hence the degenerative fatty change known as atheroma, which occurs in the arterial tunics as a result of arteritis, is the chief factor caus- ing a predisposition to aneurism. Anything that in- sº duces the atheromatous change, such as advancing Sacciform aneurism age and alcoholic intemperance, may be an indirect from injury. The ar- cause of aneurism. Unusual muscular exertion, by tery laid open to show inducing violent heart action and preventing rapid opening into sac. admission of blood into the capillaries, causes in- (BRYANT.) creased intravascular pressure, and thus may be the immediate cause of an aneurismal dilatation If the artery is previously atheromatous the sudden strain causes the inner coat to give way at a point where an atheromatous patch is situated; the fatty pulp, lying under the inner layer of the inner tunic, is evacuated, and thus in the integrity of the wall a breach is made which allows distention to occur under the force of the blood stream. Continuously laborious occupation is not so dangerous in this regard, for the vessels seem to acquire strength by the gradual accession of great intravascular tension. It is a sudden Strain, in vessels unused to such a degree of tension, and which are pre- viously degenerated, that tends to cause such damage. External violence without a wound, such as blows and concussions, may loosen the membrane covering an atheromatous spot and induce aneurism in much the same way. Internal strain upon the arterial walls is in- creased by postures which cause flexures of the vessel; by over-tight clothing, especially around the neck; and by the anatomical division of the artery into two branches of nearly equal calibre. The blood-flow is retarded by these conditions, and consequently the lateral pressure is in- Cºased. Hence, aneurism is more liable to occur when sudden muscular effort is made or any unusual strain is thrown upon the walls of an artery under such disadvantageous circumstances. Sometimes a “ giving way” 266 D IS E A S E S OF T H E A R T E R I E S. sensation is felt at the time of the violent exertion. This is probably caused by a rupture of the middle coat, and may, perhaps, occur in a healthy artery. There appears to be an imperfectly understood connection between heart disease and the occurrence of aneurism. Embolism is believed by some authors to cause the development of aneurismal dilatation. This is espe- cially so in infective embolism from ulcerative endocarditis and other septic processes. As the aneurism occurs at and not above the point of lodgement of the embolus, the lesion is supposed to be due to a local arteritis resulting from the septic character of the embolus. This is the explanation of the well-known non-occurrence of aneurism in cases of non-infective embolism. Syphilis has been regarded by some writers as a cause of aneurism. This is doubtful, since syphilitic arteritis seldom attacks the larger arteries, and it is here that aneurism is more commonly met. It is pre- eminently a disease of small vessels. I am, of course, speaking now of surgical aneurism, not of aneurism of arteries of the brain. Finally, wounds of arteries may be followed by aneurism. The subject of trau- matic aneurism has, however, been discussed in a previous section, and requires no further mention here. When an atheromatous spot has given way, as described above, and the pressure does not cause complete perforation of the wall and hemorrhage, it is usually a sacciform aneurism that is developed. When, however, there is an absence of normal and of inflammatory adhesion between the tunics and their component layers, separation of the arterial coats may be induced by the blood current insinuating itself between them. Thus may be caused on rare occasion separation of the arterial coats, the so- called dissecting aneurism. PATHOLOGY..—Dissection of a sacculated aneurism shows on the out- side an investment or covering of cellular tissue, resulting partly from inflammatory condensation, partly from atrophy of the muscles and other structures that have been subjected to pressure by the increasing tumor. Within this more or less imperfect investment is found the true aneurismal sac, consisting of one or more of the arterial tunics which have become so thickened, blended, and changed by interstitial growth that it is usually impossible to determine their exact identity. The inner and middle coats can sometimes be recognized by the patches of atheromatous degeneration visible in their structure. In large aneurisms the two inner coats have usually disappeared ; indeed, the outer one may be absent in places and its place be supplied by the external investment above mentioned and the laminated fibrine contained in the sac. The true sac is of varying thick- ness in different regions of the tumor. It is evident that in all aneurisms, except in the very smallest, there must be a natural growth of the sac wall after the pouch has first been formed, for the area of tissue that constituted the arterial wall at the site of disease could not possibly be stretched so as to form a sac of such dimensions. The irregular thickening and thinning of the Sac depend upon the force of the blood current in the aneurism. Where the blood impinges with the greatest force, there will the sac be thinnest. Inside the true sac there will nearly always be found numerous concentric layers of more or less completely decolorized fibrine. The layers of fibrine nearest the sac wall are tougher and more yellow than those nearer the centre of the aneurism, which are softer and somewhat reddish. This laminated fibrine is found especially in those irregular pockets or pouches A N E U R IS M . 267 of the sac which are away from the rapid current circulating in the aneurism. This deposition of fibrine is encouraged by any agency, whether within the aneurism or entirely foreign to it, that diminishes the force of the current within the tumor. When fibrine has once begun to form upon the inner wall of the sac it has a tendency to increase by further deposition of the blood. Thus, layer after layer is formed. The outer layers, being the oldest, naturally become more decolorized and tougher. The laminated fibrine is a beneficial provision of nature for, by reason of its tough, fibrous nature, it strengthens the sac wall and acts as a pad to lessen the force of the pulsating blood current, which is tend- ing to distend and rupture the sac. Moreover, it lessens the capacity of the sac, and by its continual deposition tends to fill up and obliterate the cavity of the aneurism. Fusiform aneurisms usually contain little or no laminated fibrine. At the centre of the aneurism, within the concentric layers of fibrine, there will be found a mass of soft, black or reddish- black clot, or a mixture of such clot and fluid blood. This soft clot may be an ante-mortem or a post-mortem formation. The secondary changes produced by an aneurismal tumor are numerous and are due especially to the pressure exerted by its growth. Thus, oºdema, varicose veins, and venous occlusion may occur from pressure on the veins; and neuralgia, paralysis, anaesthesia, obscure pains, and “tired "sensations may result from nervous compression. Aphonia may follow if the function of the recurrent laryngeal nerve is interrupted. Organs are displaced, bones and cartilages eroded and perforated, synovial sacs opened, gangrene of distal parts determined, and many other de- structive processes inaugurated before death or cure occurs. Gangrene may be due to pressure causing interference with circulation to the parts below, or to a portion of laminated fibrine or soft clot becoming detached and being washed into one of the distal branches and plugging it. SYMPTOMS.—The symptoms of aneurism are usually of gradual develop- ment, but occasionally it happens that the patient experiences a sensation of something giving way, which is accompanied by a sudden, sharp pain, and is followed by the appearance of a tumor. An aneurismal tumor is usually rounded or oval in outline, and is covered by healthy skin, unless suppuration or ulceration is taking place. These events occur only in the last stages of the disease. An aneurism gives rise, as does any other tumor of similar size and location, to certain pressure effects. These symptoms are in no way charac- teristic, and do not aid in establishing a differential diagnosis. In addi- tion there are symptoms depending upon the relation of the aneurismal tumor to the circulation. These are peculiar, and, when found in combi- nation, are pathognomonic of aneurism. The pressure of an aneurism may give rise to a pain, numbness, muscu- lar weakness, or paralysis, venous congestion, cedema and varicosities, gangrene, obstruction to breathing and swallowing, and many other symp- toms due to interference with the function of special organs. Hoarseness, Spasmodic dyspnoea, cough or uncontrollable eructation may be produced by pressure upon the laryngeal or other branches of the pneumogastric nerve; facial distortion, deafness, ptosis, or strabismus from similar involve- ment of cranial nerves; boring pain or even synovitis from erosion and perforation of bones and cartilages, and nutritive changes from involve- ment of lymphatic vessels or thoracic duct. The pressure effects of an aneurism are apparently more rapidly developed than those of an ordi- 268 D IS E A SES OF THE ARTE RIES. nary tumor of similar size. This is probably due to the pulsating charac- ter of the former. The symptoms due to the circulatory relations of the aneurism may be called intrinsic symptoms, and are five in number, namely, location, change in tension, pulsation, thrill, murmur. An aneurism is necessarily located in the course of an arterial trunk, and cannot be displaced from its connection with the artery. If occluding digital pressure is made upon the vessel below the aneurism, the tumor becomes more tense and less compressible; and if the sac contains but little laminated fibrine and has thin walls, the tumor may even become larger than usual by the stretch- ing influence of the unusual amount of blood dammed up in it. If the entrance of blood into the sac is prevented by pressure upon the artery above the aneurism, the tension is diminished and the tumor becomes com- paratively flaccid and compressible. The elastic bandage when tightly applied to the limb, as in bloodless operating, often causes a marked dimi- nution in the size of the tumor. It may do harm, however, by displacing portions of fibrine and causing embolism. The compressibility or non-compressibility of individual aneurismal tumors is chiefly determined by the absence or presence in them of a large amount of laminated fibrine. The variation in compressibility or ten- sion, observed when the exit or entrance of blood is checked, is due to the degree of distention of the sac by its circulating blood contents. When the sac contains much fibrine, or has a thick wall, this symptom is not well marked. The pulsation of an aneurism is a peculiar expansive beat, which not only lifts the fingers or hand laid upon the top of the tumor, but drives apart the fingers or hands when the tumor is grasped laterally. This lateral pulsation is due to the fluid contents of the aneurism transmitting the shock of the heart-beat equally in all directions. When the sac is largely filled with fibrine, and, therefore, has little blood contents, this lateral pulsation is less marked, and only a dead thud is perceived. Another peculiarity of aneurismal pulsation is the wave-like movement. The pulsation does not seem to affect all parts of the tumor simultane- ously, but swells up somewhat gradually as if propagated from one point, and then in a similar way subsides. Pressure upon the artery above the tumor arrests pulsation ; pressure below it and elevation of the limb have a tendency to make it more marked. Aneurisms with large orifices, and which contain little fibrine, present the most characteristic pulsation. In partially solidified aneurisms the pulsation may be absent or obscure, or may resemble the simple rise and fall of a solid tumor lying upon an artery. Pulsation may also be absent because of rupture of the anuerism, because of inflammatory infiltration between the sac and the surface, because loose clots have plugged the orifice of communication, or because the disease has just been spontaneously cured, and the tumor has not yet entirely disappeared. When the artery is compressed above the seat of disease, so that no blood enters the sac, the tumor, as previously stated, becomes pulseless and flaccid. If the tumor is now grasped laterally, and the pressure upon the vessels suddenly removed, the expanding pulsation by which the sac is instantly refilled, is readily felt and even seen. When the sac has a large mouth, one pulsation distends it fully; if the orifice is small, the sac fills more slowly, but the first pulsations are strong beats. The arterial pulse below the aneurism is much less marked than on the opposite side of the body. This may be due to pressure of the tumor on A N E U R IS M . 269 the artery, to arteritis causing occlusion, or to the rigidity of calcification. It is possible that it may also be caused by the large amount of blood in the sac distributing the pulsation and lessening that in the current below. This variation in the two radial arteries is of aid at times in diagnosticat- ing aneurism of the thoracic aorta. Just after the heaving pulsation of an aneurism, the hand of the examiner can often perceive a peculiar tremulous or vibratory movement called the thrill. The thrill is due to the rebound of the blood column, and is said to be more distinct when the artery lies between the sac and the surface upon which the hand is placed. The last of the five intrinsic symptoms of aneurism is the murmur or bruit. This is an intermittent blowing, rasping, or purring sound due to the blood rushing through the narrow mouth into the dilated cavity of the sac. It is heard by applying the ear either with or without a stetho- scope to the surface of the tumor. The tone varies greatly, depending on the size, shape, and location of the orifice, its relation to the sac, and perhaps upon the character of the surrounding tissues. It is most dis- tinct in fusiform aneurisms and sacciform aneurisms with large mouths. It is synchronous with the aneurismal pulsation, and is stopped by pres- sure on the artery above the sac, but returns as soon as the pressure is removed and the blood allowed to flow into the sac. If the tension of the sac is lessened by elevating the limb or by compression of the artery above the tumor, the murmur may sometimes be heard in cases in which it was previously absent. Increasing the tension by pressing upon the artery below would, on the other hand, have a tendency to diminish the murmur. If the orifice is very small or the sac nearly filled with fibrine there may be no murmur generated. The aneurismal murmur is not in- frequently absent, and, indeed, may be present at one time and afterward disappear. A double murmur indicates, according to Erichsen, a sacci- form aneurism. - These intrinsic symptoms may not all be present in a given aneurism, but the association of two or more of them usually renders the diagnosis quite clear. When an aneurism ruptures, permitting the blood and clots to become diffused, the tumor loses its definite outline and becomes rapidly larger. Pulsation, thrill, and murmur become obscure or absent; pain increases, and coldness, lividity, and oedema of the extremity are apt to occur. The subcutaneous hemorrhage may cause syncope. Coagulation of the blood and inflammatory condensation of the cellular tissue may in very occa- sional instances limit diffusion after the rupture and lead to spontaneous cure of the aneurism. Usually, however, the swelling increases, and the case terminates in gangrene or suppuration, accompanied most likely with hemorrhage. DIAGNOSIS.—The differential diagnosis of aneurism from other tumors should always receive careful and systematic attention. No swelling near an artery should ever be laid open until the possibility of aneurism has been eliminated by accurate examination. The pain caused by internal aneurism may, when the tumor is not easily discoverable, be mistaken for rheumatism or neuralgia. Such an error is hardly probable in the external aneurisms that come under the observation of surgeons. There are two circumstances that at times render the differential diagnosis of aneurism troublesome, First, there are pulsating tumors that are not aneurisms; and secondly, there are aneurisms that do not pulsate. Any solid or cystic tumor or abscess situated over a large artery may 270 D IS E A SES OF T H E A R T E R II. S. show transmitted pulsation. The pulsation in such cases is not so expan- sive as in aneurism, but is rather a simple rise and fall which may be diminished or stopped when the tumor is pushed or lifted away from the artery. Flexing the limb so as to relax the deep fascia will probably lessen the pulsation, which, moreover, is sometimes felt only in the line of the artery and not over the entire tumor. There is no murmur, or if any, it is only a dull beating such as is heard when an artery is com- pressed with a stethoscope. The tension and size of such tumors are not affected by occluding pressure upon the artery above or below the swell- ing. The suddenness with which aneurisms regain their usual size when arterial pressure on the cardiac side of the tumor is removed is very characteristic, and is not present in tumors with a mere transmitted pul- sation. Cysts or abscesses communicating with a joint, or with the abdominal or any other cavity, may be partially emptied by pressure; but they refill afterward without reference to the arterial circulation. An abscess sit- uated above or surrounding an aneurism will appear as a tumor having pulsation, and some of the other symptoms of aneurism. Such cases are fortunately rare. The aspirator would be available for establishing the diagnosis. If the suppuration is due to rupture of the aneurism the opening between the sac and the pus collection will permit hemorrhage to follow the opening of the abscess. Pulsation is usually feeble or absent in such conditions, and unless the previous history is obtained the surgeon may be misled into laying open the tumor. The fatal bleeding may not occur until some hours after the incision, because the laminated fibrine may for a time act as a barrier. A murmur should be carefully sought in such cases, since it is less likely to be absent than other aneurismal phenomena. w Some vascular tumors or angeiomas resemble aneurisms very much. They are apt, however, to have a more spongy feel, and are not so dis- tinctly circumscribed as aneurisms. If the blood is pressed out of such a tumor it returns somewhat tardily and irregularly, causing the tumor to dilate slowly and unevenly, and not with the sudden bound that is seen in aneurisms. Pressure upon the artery below causes no marked increase in size of tumor. The pulsation is not as forcible or as distinct as an aneurism, and it lacks the expansive and wave-like character of the pul- sation found in the latter disease. The murmur is more confused and less well defined. The introduction of a hollow needle will probably give exit to blood, but the blood will scarcely spurt as in the event of puncture of an aneurismal sac, nor will the needle be likely to give to the surgeon's hand the sensation of having its end in a cavity. Malignant tumors, especially sarcomas of the bones, may, when very vascular, assume pulsation. If in localities where aneurism is common the diagnosis becomes at times almost impossible. The history of such growths generally shows that pulsation was not present when the tumor first appeared, and that the growth has recently become of softer consist- ence than formerly. Careful examination shows that the pulsation is not very distinct, that the murmur is soft and subdued, and that little varia- tion in size is produced by pressure on the artery between the tumor and the heart. The pulsation and murmur after having once appeared do not, as in aneurism, become more conspicuous as the bulk of the growth is augmented; often these phenomena are perceptible only over certain parts of the tumor. Involvement of the adjacent lymphatic glands sug- gests malignant disease, which, moreover, is apt to be more or less irreg- A N E U R IS M, 271 ular in outline. In very obscure cases an attempt might be made to remove a small portion of the interior of the tumor for microscopic ex- amination by inserting an instrument such as is used for cutting out pieces of muscle in cases of suspected trichinosis. Aneurisms that are devoid of pulsation may be mistaken for deep abscesses and for granular, fibroid, and other tumors. The pulsation ceases in an aneurism when spontaneous consolidation has occurred, or when rupture or diffusion of the blood contents has taken place. An aneurism, when spontaneously cured by consolidation, continues for a long time as a hard mass, which finally shrinks and disappears. Such a mass cannot easily be distinguished from other hard tumors except by the history. A tumor located near an artery, especially if it shows a tendency to decrease, should, therefore, be well scrutinized before any operative treatment for extirpation is attempted. When a small rupture of the sac occurs, the effused blood conceals pulsation, changes the ordi- nary globular shape of the aneurism, and, by gravitating away from the seat of disease, may make the tumor appear to have a site distant from the line of the artery. Moreover, the superficial veins may become unusually marked, because the circulation in the deep veins is interfered with by reason of the pressure. This circumstance gives the tumor the appearance of malignant disease. Aneurisms, which are the seat of small ruptures, are, therefore, at times diagnosticated from solid tumors with difficulty. The diagnosis is easily made when the rupture is large, for the interruption of circulation in the limb below, the swelling, pain, ecchymosis, and rapidly occurring suppuration and gangrene are quite distinctive. If suppuration occurs around an aneurism, from inflamma- tion due to pressure or to rupture, pulsation may be absent. The careless surgeon may plunge a bistoury into such a swelling and cause fatal bleeding. This has been spoken of above. Finally, abnormal pulsation of an artery is at times noticeable in con- ditions of debility and in nervous subjects, and may be mistaken for aneurism. The absence of lateral or expansive pulsation and of a tumor serves to dispel the illusion. COURSE AND TERMINATION.—Untreated aneurism generally continues to increase in size until death occurs from : (1) Pressure interfering with important organs, such as the trachea, pneumogastric nerve, or heart; (2) syncope, from weakness of cerebral circulation beyond the large sac ; (3) embolism of the cerebral arteries from fragments washed from the laminated clots; (4) rupture and hemorrhage; (5) gangrene, from pres- sure on the vessels of the limb. When an aneurism bursts upon a serous surface the hemorrhage is usually rapid, and occurs through a slit or star-like tear; but when the rupture is upon a mucous surface, the bleeding is apt at first to be intermittent and so slight as scarcely to attract atten- tion as it oozes through a small fissure. Subsequently, on the occasion of Some increase in blood pressure from emotion or exertion, a small slough gives way and a sudden gushing hemorrhage supervenes through a small circular apeture. Rupture upon the cutaneous surface takes place, as a rule, by the processes of ulceration or suppuration and pointing as in abscesses. Rupture of the sac may, of course, occur without external Communication. In such cases the blood is effused among the muscles and fascias, and commonly leads very promptly to suppurative or gangrenous inflammation. Occasionally, but rarely, an aneurism is cured spontaneously. Any *gency that lessens the blood-current and thereby encourages the deposi- 272 D IS E A SES OF T H E A R T E R I ES. tion of laminated fibrine and the coagulation of blood in the sac, may be a factor in this fortunate issue. , Absolute quiet of mind and body and maladies that depress the general circulation or draw the mass of the blood to a region distant from the seat of aneurism, have this tendency. The ameurism itself or some other tumor may compress the artery above the seat of disease, and thus diminish the current through the sac. Sponta- neous cure may also occur from occlusion of the vessel above or below the disease by an embolic plug swept from vegetations in the heart, or from the fibrine in the aneurismal sac ; from inflammation of the sac wall, causing within the aneurism the formation of soft clot; from sup- puration; from rupture; and from gangrene. Any of these processes may at times fortunately cause sealing of the vessel and obliteration or destruction of the sac ; but they are dangerous complications not often attended by such a gratifying result. TREATMENT.-The medical or constitutional treatment of aneurism is important, even in those instances that require additional surgical inter- ference. Absolute rest of body and mind must be enforced by keeping the patient in bed in the recumbent position, and free from the excitement of talking. He should be cautioned to avoid rapid or frequent move- ments of the limbs, and not to rise in bed unless aided by attendants. He should not get out of bed on any pretence. The food should be limited in quantity, and free from stimulating or indigestible ingredients. Very little water or fluid diet should be given. The design of these precau- tions is to diminish the bulk, and retard the circulatory force of the blood in order that deposition of laminated fibrine in the sac may be encouraged. These objects may be further obtained if the patient is robust and plethoric by a moderate bleeding from the arm, and the administration of aconite and veratrum viride in comparatively small doses. Bromide of potassium, hydrate of chloral, and the other narco- tics may be employed here, and also in a debilitated subject to induce circulatory repose. Iodide of potassium has been strongly recommended in the treatment of aneurism. It should be given in doses of 20 to 30 grains two or three times daily. The medical treatment just delineated is the only treatment applicable to the majority of internal aneurisms, as aneurisms within the cavities of the trunk are called. It should also be employed as an adjuvant to surgical measures in cases of external aneurism. Though cure of any form of aneurism by medical means is rather unusual, amelioration of symptoms and retardation of progressive enlargement are their common sequences. Fusiform aneurisms cannot, but sacciform aneurisms may, be cured by such measures. Many surgical expedients have been devised for dealing with aneurism. There are but three that possess sufficient value to be discussed in this treatise. These are: 1. Excision of the tumor, which is applicable to very small aneurisms only, such as occur in the fingers. 2. Compression of the artery above the tumor by instruments, the fingers, flexion of the joint, or the Esmarch apparatus. 3. Arterial ligation. - Galvano-puncture, acupuncture, the introduction into the sac of foreign bodies, such as horsehair or wire, injections of coagulating liquids, such as the iron compounds, manipulation which aims to detach fragments of fibrine and plug the distal orifice of the sac, and the other proposed A N E U RIS M. 273 methods are either far inferior to, or much more dangerous than the pro- cedures mentioned above. Still it may be justifiable to resort to one of these methods when those recommended are impracticable. Amputation may be demanded as a last resort in order to save life in aneurisms of the extremities that threaten immediate death from hemor- rhage or gangrene. Excision of the aneurismal sac is applicable only to small aneurisms such as occur in the hands and feet. In these situations excision is some- times to be employed because the intimate anastomosis of vessels renders solidification of the aneurism by either compression or ligation of the main vessels of the limb difficult. The method is simple. After the application of the Esmarch apparatus the tumor is dissected out as any other growth would be and the vessel tied above and below the seat of dilatation. The wound is then brought together with sutures. A some- what similar method, which may be called the incision method, is at times justifiable in large aneurisms, though it is seldom employed except in cases of rupture or accidental puncture of an aneurism. After the circu- lation has been controlled by compression or the Esmarch apparatus, the sac is incised so that the clots can be turned out and the orifice in the artery discovered. Into this aperture a probe is passed to enable the operator to detect the position of the vessel, which is then ligated above and below the opening. The wound is afterward brought together by sutures or packed with some antiseptic dressing and allowed to granulate. Compression, as a method of treating aneurism, may be applied directly to the tumor, or to the artery, either above or near the seat of disease. Pressure applied directly to the tumor or to the artery on the distal side of the aneurism is seldom effective and needs no further description. Proximal arterial compression is the form adopted in all cases; for even in those in which flexion is employed it is the compression exerted on the artery above the sac that is the chief element of value. Compression of the artery above the aneurism acts by diminishing or completely arresting the flow of blood through the sac. This, in the one case, encourages gradual deposit of laminated fibrine which finally fills the pouch and leads to solidification; and in the other, causes the sac to become filled With soft clot, after which, under the influence of absorptive and con- tractile influences, the aneurism shrinks and becomes obliterated. It is probable that here, as in ligation, the more certain and safe treat- ment is that in which the pressure is so regulated that a small amount of blood is allowed to enter the aneurismal pouch during the application of the compressing force. Thus, a slow, laminated deposit of fibrine occurs and the sac becomes hard and solid. When sufficient pressure is made upon the artery to close its calibre entirely, the anastomosing arteries, if the pressure is continuous, will soon carry a small blood-stream through the tumor, provided a branch leaves the main trunk between the seat of Compression and the sac. The conditions are thus identical with those obtaining after Hunter's method of ligation; providing the occluding pressure is maintained without interruption for a sufficient number of hours and is not changed to a point below the origin of the branch through which the small reversed current is to enter the main trunk. When the compression is only sufficient partially to close the arterial calibre, a small amount of blood necessarily enters the pouch by the Qrdinary route, and the therapeutic conditions are similar to those just described. When the complete compression is made so near the sac that no intervening branch exists all access of blood to the sac is stopped and 18 274. D IS E A S E S OF T H E A R T E RI E S. it becomes filled with soft clot. Cure must then result as in Anel's method of ligating, and with the same liability to failure from inflammatory reac- tion due to the pressure of the soft coagulum. *...* ºr ==E=- v.--> gº º *** º: *...* > ...,' ... < §§§tº !Cº. §:#:*** -- .. ź. wº- $ºlº.º. ººr.

It takes longer to fill the sac with deposits of laminated fibrine than with soft, homogeneous coagulum; but reasoning from what is seen after ligation I am inclined to recommend it as the surer and safer method. Therefore, that complete compression, as a rule, should not be employed unless the pressure can be applied far enough above the aneurism to in- sure the existence of an intervening branch which will carry a gentle current of blood through the sac, partial compression may be employed even near the aneurism because it allows a portion of the current to pass through the vessel at the seat of pressure and thus enter the sac. By complete compression is not meant such a degree of force as will cause inflammation of the tunics and permanent occlusion of the artery; merely such pressure as will bring the opposite walls of the vessel in con- tact and prevent the passage of the blood current during the continuance of the pressure. This sort of compression should be continued for from four to ten hours, and usually requires anaesthesia during the whole period, for the prevention of discomfort and actual pain. When the aneurismal tumor appears to have become consolidated, which may occur in a short time, the pressure may be somewhat relaxed ; but partial compression at least should be maintained for several hours longer. If this is not done, the sudden rush of blood may displace the fibrinous deposits in the sac ; or, if the coagulum is merely soft, may cause its disintegration and thus destroy the prospects of cure. Partial compression, which allows some blood to flow through the artery at the point of pressure, is more tolerable to the patient than com- plete compression, and, therefore, does not require anaesthesia. Narcotics may be demanded, however, to relieve distress occasioned by the restraint. This method of treatment must be continued for days, and perhaps for two or three weeks, because the blood current, though greatly diminished in volume, is sufficient to prevent rapid solidification in the Sac. Either form of compression may be employed continuously or inter- ruptedly. Continuous compression is probably better than interrupted compression, whether complete or partial, because cure is more rapidly attained. It quite frequently happens, however, that treatment by either complete or partial compression requires so many hours or becomes so irksome to the patient, that it is necessary to suspend its employment from time to time. The intervals of non-treatment should be generally at A N E U R IS M . 275 night, so that the patient may have every opportunity for obtaining rest and sleep. In the case of complete compression an intermission of Several days is at times advisable. During the intermissions the patient should be kept perfectly quiet in bed. The Sac is finally filled, if cure be effected, by successive layers of fibrine deposited during the periods of pressure. The best method of compression probably is continuous complete com- pression applied far enough above the aneurism to insure the existence of an intervening branch to carry a little blood into the sac. If this form of treatment is not adaptable resort may be had to continuous partial compression. After an aneurism has been cured by compression there is usually no obliteration of the artery found at the point of pressure. In the Sacciform variety there is in some instances no obliteration even at the seat of the tumor, but the circulation goes on through a groove or channel in the solidified aneurism. Fusiform aneurisms are not very amenable to treat- ment by pressure. Before compression is begun the patient should be confined to bed for three or four days, that he may become accustomed to the restraint and to urinating and defecating in the supine posture. The limb should be shaved and washed, and the skin at the seat of pro- posed pressure sprinkled with chalk, oxide of zinc, Soapstone, or other unirritating powder. The bed should have a firm mattress upon it. The intelligent coöperation of the patient should be obtained, for much depends upon the continuous perfect adjustment of the compressing force whether it be digital or instrumental. Bromide of potassium, chloral and morphia are often valuable agents for keeping the patient comfortable. When about to apply the compress- ing force the surgeon should, by momentary pressure on the distal portion of the artery, cause the sac to become well distended with blood. The finger or pad is then adjusted to the artery above the aneurism before the distal pressure is relaxed. Gentle compression of the tumor by an ordi- nary bandage applied up the limb during the time of treatment possibly conduces to hastening contraction of the sac. Inflammation of the skin or cellular tissue at the point of compression calls for temporary cessation of treatment. . The best compressing force is that exerted by the human finger. This is called digital compression, as opposed to instrumental compression, Which is obtained by tourniquets, suspended weights, or similar appara- tus. Digital compression necessitates relays of physicians or trained assistants, since one person cannot exert effective digital pressure continu- ously for more than ten or fifteen minutes. Two persons should be with the patient constantly. The first makes pressure on the artery with his thumbs placed one upon the other, while the second keeps his hand on the surface of the aneurism to see that absolute cessation of pulsation is main- tºined. When the first becomes tired of pressing, the second places his thumbs upon the vessel just above or just below the point compressed by his companion and controls the circulation before the latter relaxes his Pressure. He that was the compressor now watches the tumor to see that Pulsation does not return from inefficient arterial occlusion. Instead of using the muscular power of the second hand to reinforce the thumb placed ºver the artery, the compressor may have a bag of shot or a tourniquet * adjusted as to press upon the back of his thumb. This renders the 9Pºrºſion less wearisome. Intelligent assistants are required for carrying * digital compression, since the pressure must be made in that direction 276 DIS E A SES OF T H E A R T E RIES. which will press the artery against the bone; and must not be made upon the vein if is possible to avoid it. The femoral artery should be controlled by pressure below the groin directed backward against the head of the femur. The brachial artery at its upper part is compressed by pressure outward and backward against the shaft of the humerus. The amount of force should be no greater than that which stops pulsation in the tumor. It is for these reasons that the finger-tip of an intelligent person is far better than any pad that can be devised by instrument-makers. Complete occlusion can, therefore, generally be maintained without anaesthesia. Another, though indirect advantage of digital compression, is the constant presence of the assist- ants, which serves to interest and encourage the patient. When trained assistants are not obtainable, FIG. 106. digital has to be substituted by instrumental * , w pressure. Sometimes one method may be used as an adjuvant to the other. Various tourniquets and compressors have been devised for making pressure on the ar- tery. The essential point is that the venous circulation shall be interfered with as little as possible; hence a small pad controlled by a screw or spring and a larger pad to make counter-pressure on the opposite side of the limb are characteristics of nearly all these instruments. Sometimes there are a series of small pads so that pressure can be applied alternately to different parts of the artery, and thus relieve the integument from inju- rious pressure. The same object can be ob- tained by using two single pad tourniquets placed a few inches apart, one of which can be relaxed while the other is screwed down upon the vessel. gº These methods are objectionable when the Watson's weight compressor. varying points of pressure cause different The dotted line indicates the anastomosing branches to carry on the collat- position of the limb. eral circulation, for too much blood may reach the sac in case ligation is required after failure to cure by compression. A single pad is probably preferable, supple- mented, if necessary, by digital compression applied near the same spot. A conical weight or a bag of shot may be suspended or other means arranged so as to make arterial compression. When the aneurism is of the brachial artery at the elbow, or of the popliteal artery, compression by flexion may be employed as a method of treatment. This mode consists in keeping the elbow or knee firmly flexed so as to bend the artery and at the same time exercise pressure on the tumor itself. The circulation through the sac is thus greatly lessened. The flexed posture can be maintained by applying a collar around the limb above the joint and another below it, and preventing extension by a short chain attached to both. A more simple means is an ordinary roller bandage applied by figure-eight turns. The forced flexion should be sufficient to check pulsation completely in the sac, but the joint should not be flexed to such an acute angle as will make too violent pressure on the aneurism or injure the articulation. It is not satisfactory in large A N E U R IS M. 277 aneurisms, nor in those tending to inflammation. Rupture or suppura- tion may be induced by it in such cases. In small aneurisms and as an adjuvant to digital or instrumental compression, flexion has a value. FIG. : 07. º- * wº- sº ſº |*:::C- 2-Hº- === Sº Briddon’s compressor. Cure of aneurism at the elbow or knee has occasionally been obtained by voluntary maintenance of the flexed position. So, indeed, has digital compression, of the interrupted kind exerted by the patient’s own fingers, effected a cure of aneurism. FIG. 108. Signorini’s tourniquet. The last method of employing pressure is what may be called general *Pression, and is accomplished by the Esmarch apparatus. A rubber bandage is applied, as in preparing for amputation, from the distal ex- 278 D IS E A SES OF T H E A R T E R IF. S. tremity of the limb to the lower end of the aneurism. The surface of the aneurism is then left uncovered and another elastic bandage firmly applied above it, or the first bandage is carried loosely around the loca- tion of the tumor and applied tightly to the limb above. Near the trunk the application of the bandage is discontinued and the limb is encircled by the thick elastic band, which plays the part of a tourniquet. The access of blood to the limb is thus cut off and the other bandage or bandages are removed. The tumor, however, is left distended with fluid blood in a state of rest, which soon coagulates. It is perhaps well to delay a mo- ment when the elastic bandage has been applied as far as the lower end of the aneurism, so that the current from above may fully distend the sac before the vessel is compressed on the proximal side of the tumor. The circulation should be kept out of the limb for about an hour, unless there is some contra-indication. Before the constricting cord is removed complete digital or instrumental pressure should be made upon the artery above it, lest the sudden current wash away or break up the soft, black clot in the sac. This, or moderate compression at least, should be kept up for a few hours afterward to allow the clot to become firmer. Anaes- thesia will be required when the Esmarch apparatus is used, FIG. I 09. * ~~ Tuſhell’s truss-like compressor applied. (ERICIISEN.) If the aneurism does not show absence of pulsation after this treatment, the patient should be let alone for a week before a second trial is made. In the meantime efforts to increase the coagulability of the blood may be carried on. These have been described under the medical treatment of aneurism. General compression seems to be most applicable to recent aneurisms of moderate size with walls that are not very thin. It is to be avoided or only applied with extreme caution and for short periods in patients whose vessels are markedly atheromatous. Danger of inducing gangrene is, under such circumstances, very great. A N E U R IS M . 279 When ligation becomes necessary, after failure in curing by the Es- march apparatus, the surgeon should not attempt to apply the ligature at the point where the constricting band encircled the limb. The peri-arte- rial structures are liable to be infiltrated or inflamed at this point. A higher or lower point should be selected. . This rule should be followed in ligating after any form of compression has been previously employed. The comparative advantages and disadvantages of compression in the treatment of aneurism claim attention. Though not without risk of in- ducing erysipelas, inflammation, and suppuration of the sac, thrombosis and gangrene, compression is safer than ligation. This is probably true, notwithstanding the fact that the use of catgut and similar aseptic liga- tures has reduced very greatly the risks formerly associated with ligation. Partial compression has, however, the disadvantage of being a more tedi- ous method than ligation, and is not available when the patient is fretful or the disease rapidly increasing. Neither form of compression is to be attempted when the limb is inflamed or oadematous. It is probable that the development of the collateral circulation due to the compression acts at times as a source of failure when subsequent ligation is demanded by inefficacy of compression as a means of cure. On the other hand, the same effect may be a preventative of gangrene after ligation, especially in the old, whose arteries are not well fitted to carry on the collateral cir- culation after ligation, unless previous gradual enlargement has been effected by compression. Compression is not serviceable, as a rule, in the cure of fusiform 8,IlellTISIOl. º The rules for employing compression then may be formulated as fol- lows: Use it: 1. In aneurisms of recent development and when the success of subse- quent ligation is not much imperilled by its use. 2. When ligation is especially dangerous, as it is in the aged, during epidemics of erysipelas, and in certain locations of the body. 3. Experimentally for five to seven days in nearly all cases. If nothing is gained by compression in the course of a week, it is usually proper to resort to ligation. Arterial ligation for the cure of aneurism has been practised in four ways, of which two are practically valueless. Of the two remaining methods one is always preferred, except when the proximity of the aneurism to the heart renders its performance exceedingly dangerous. This method is called the Hunterian method. . It consists in applying a ligature to the artery between the aneurism and the heart, and at such a distance from the former as will insure the existence of a small branch leaving the artery between the ligature and the seat of disease. The ligature on being tied arrests at once the current in the main artery and Would entirely stop the blood flow through the aneurismal sac, if the small branch mentioned did not exist. This small branch, which has an anasto- mosis with branches given off from the main vessel above the site of liga- tion, Soon, by dilatation and reversal of current, carries a small amount of blood into the main vessel below its origin, and thence through the aneurismal sac. Thus, it is seen that the Hunterian method of ligation does not entirely arrest the current through the sac, but merely diminishes it very greatly, Deposition of laminated fibrine, which is the method of Spontaneous cure which is most desirable, is thus determined, whereas entire arrest of the current would have caused the formation of soft clot 280 D IS E A S E S OF T H E A R T E R I E S. in the sac, which may, it is true, cause final solidification, but which is apt to be followed by inflammation of the sac.

Of the three other methods of ligation one is a proximal ligation, that is, on the side of the disease nearer the heart, and two are distal liga- tions, that is, on the side away from the heart. Table of the four methods of ligation in treating aneurism. Proacimal Ligations. Anel's.-Ligature applied close above aneurism with no intervening branch. Objections: 1. Difficult, because artery is overlapped or displaced by Sà,C. 2. Causes total arrest of blood current, hence soft clot and tendency to inflammation of sac. 3. Artery probably atheromatous, hence tendency to secondary hemorrhage. Hunter's.-Ligature applied at some distance above aneurism, so as to have an intervening branch. Advantages: 1. Easy of performance. 2. Causes partial arrest of blood current, hence firm fibrinous deposit. 3. Artery much more likely to be healthy. A N E U R IS M . 281 Distal Ligations. Brasdor's.—Ligature applied just below aneurism. Objections: Same as in Anel's. Wardrop's.-Ligature applied to trunk a little below first branch or to first branch a little below its origin from the trunk. Advantages: Same in kind as those of Hunter's method, but it is less successful in causing solidification because current is not arrested sufficiently. Never used except in aneurism of innominate or of root of common carotid artery and then it is adopted because the Hunterian method is impossible. FIG. III. Diagrams showing Anel, Hunter, Brasdor and Wardrop methods. The Hunterian method of ligation must be considered more fully, since it is the one to be adopted when compression is deemed impracticable. The method of exposing the various arteries and ligating them in con- tinuity is described in a subsequent section. When the catgut cord has been placed under the vessel and before the knot is tied the artery should be compressed between the cord and a finger inserted into the wound, in order to prove by absolute arrest of pulsation in the tumor that the supplying artery has been exposed. Just before the ligature is drawn tight, it is well to make pressure for half a minute upon the artery on the distal side of the aneurism in order that the sac may be fully distended with blood before the circulation is arrested. A good size catgut or flat silk ligature is to be preferred. With ligation of the vessel, pulsation, thrill and murmur in the tumor imme- diately cease and the limb below shows some elevation of temperature, which usually, however, soon subsides. Loss of muscular power, pain and hyperaesthesia are frequently ob- served in the parts below the site of operation. The tumor at first feels softer than usual, but in a few hours becomes harder and more elastic. This process of solidification continues and in a few days is completed by the transformatson of the sac into a hard ball. Contraction then begins and in the course of several weeks or months, mothing at all, or nothing 282 D IS E A SES OF T H E A R T E R I E S. but a slight thickening, is perceptible to the touch. In rare instances Some enlargement of the tumor without return of pulsation may occur after ligation from influx of blood from the distal part of the artery. This is apt to lead to the suspicion that a malignant muscular growth has been mistaken for an aneurism. A subsequent solidification of the sac clears up the doubt. A similar condition may follow compression. After the operation the limb should be enveloped in cotton-wool held in position by a bandage loosely applied, and the patient should be directed to avoid attempting to move the extremity. Quiet should be obtained by anodynes, if necessary. The cotton tends to preserve an even temperature, and protects from injurious influences the parts which have now a diminished circulatory supply. For a long time, even after consolidation of the tumor, all violent exercise of the extremities should be avoided. Impairment of muscular power, liability to suffer from ex- posure to cold, and other nutritive defects often remain permanently after arterial ligation for any cause. The Hunterian method of ligation is usually followed by the develop- ment of two collateral circulatory arches: one between the branches above the ligature and those given off between it and the aneurism, and another between the branches below the aneurism and those above it. The lower anastomosis—namely, that around the aneurism, is generally established more rapidly than that around the ligature, because the col- lateral branches in the former region have previously been enlarged by the circulatory interference occasioned by the pressure of the aneurismal tumor. This double anastomosis is due to the fact, that the artery usually becomes obliterated at the seat of aneurism as well as at the seat of ligation, but is pervious between those points. If the sac solidifies and leaves the vessel pervious opposite the seat of aneurism, or if the vessel becomes entirely occluded by clot or obliterated from the ligature to a point below the aneurism, only one collateral arch is developed. Ligation is indicated for the treatment of aneurism : 1. When compression has been tried unsuccessfully and when com- pression cannot be applied ; provided that the disease is advancing and so located that the application of the ligature is not attended with unusual risk. 2. When the aneurism has ruptured and caused hemorrhage into an articulation or into the intermuscular spaces; provided that the condi- tion does not demand amputation. - 3. When rupture into one of the cavities of the body or upon the surface, or the possibility of an early occurrence of such rupture threatens to destroy life by hemorrhage, Ligation is contra-indicated : 1. When the locality of the aneurism is such that compression can be applied. 2. When the operation is peculiarly dangerous on account of the loca- tion of the aneurism, the existence in the patient of extensive arterial or cardiac disease, or the prevalence of erysipelas or pyaemia. 3. When, on account of the proximity of large anastomosing branches or from any other circumstances, the operation would probably be unsuc- cessful. Under such circumstances ligation is justified only by impending rupture. The complications likely to arise after ligation, which may interfere with the successful solidification of the aneurism or tend to destroy the patient's life, are: recurrent pulsation in the tumor, secondary hemor- A N E U R IS M . 283 rhage at the site of operation, suppurative and gangrenous inflammation of the sac, gangrene of the extremity, pyaemia, and in special locations, secondary disease of the brain or thoracic viscera. Recurrent pulsation is due to the anastomotic arch around the ligature allowing too free a blood-current to enter the artery between the ligature and the aneurism. An anomalous distribution of the branches or abnor- mally large size of the usual branches, is the cause of this undesirable freedom of the collateral current. The employment of the compression treatment for a considerable period previous to resort to ligation, is at times an agent in developing unusually free anastomosis. Recurrent pulsation develops within twenty-four hours, and, if slight, is not likely to interfere with progressive consolidation of the tumor. If it increases in force in the succeeding few days and the tumor remains soft and with- out diminution in size or shows evidence of enlargement, the operation is proved to have been unsuccessful, and other means of cure must soon be adopted. Recurrence of pulsation after the lapse of several months is almost certainly due to the development of a new aneurism, near the site of the cured aneurism. Recurrent pulsation should be treated by elevation of the limb and moderate compression of the tumor and of the artery above the site of ligation, success will probably follow ; if not, continued progress of the disease will demand Anel's method of ligation, incision of the sac and double ligature, or amputation. Secondary hemorrhage may, after the lapse of one or two weeks, occur from the wound made at the time of ligation. This is due sometimes to an atheromatous condition of the artery preventing proper healing of the vascular coats divided by the ligature. At other times, it is caused by a large branch being given off so near the site of ligation that the collateral current coming through it into the main trunk exerts too much pressure for successful resistance by the short internal clot. Secondary hemorrhage is more frequent in the upper than in the lower extremity, because the anastomosis is more free. As rapidity of union of the wound is a barrier to secondary hemorrhage, strict asepsis and antisepsis have made secondary hemorrhage very uncommon after ligation for aneurism. The flat ligature of animal nerve or tendon, which merely approximates the arterial walls without dividing the internal and middle coats, will probably be found by future experiment to be the safest means of ligating atheromatous vessels. When secondary hemorrhage occurs, it should be treated by pressure made upon and in the wound by compression with plugs of sponge, or fine shot. If this fails the Esmarch apparatus should be applied, the wound opened freely and the artery ligated above and below the former ligature. In the event of the bleeding still continuing ligation of the artery in con- tinuity at a higher point is good practice in the upper extremity, but is Very likely to be followed by gangrene if done in the lower extremity, Where the establishment of sufficient collateral circulation is unusual. Amputation is, therefore, usually preferable in persistent secondary hemor- rhage occurring after ligation for aneurism of the leg or thigh. If the Second ligation in continuity is done in either extremity, such a point must be selected as will permit subsequent amputation if this becomes necessary. Occasionally it is possible to control secondary hemorrhage by ligating in continuity the branch through which the blood finds its way into the distal portion of the trunk originally tied. Suppurative or gangrenous inflammation of the sac may result from 284 D IS E A SES OF T H E A R T E R IES. recurrent pulsation, from incomplete anastomosis around the aneurism, from complete arrest of circulation in the sac and consequent formation of soft clot, from the great size and thinned walls of the sac, and from exter- nal violence, such as may be sustained by rough handling or kneading of the tumor either before or after ligation. The symptoms of inflammation of the sac are those characteristic of a similar process elsewhere. Suppu- ration is exhibited by the ordinary signs of abscess. When an opening has occurred spontaneously or by incision, hemorrhage becomes a promi- ment symptom. If recurrent pulsation has existed, the bleeding will be immediate and profuse; under other circumstances the escape of blood may not occur for several days, and at first will probably seem insignifi- cant. Suppuration or sloughing occurring even so late as six or eight weeks after ligation may, especially if accompanied by recurrent pulsation, be followed by fatal hemorrhage. Suppuration of the sac is to be treated by at once applying a provisional tourniquet to the artery above the seat of ligation and laying open the abscess. If bleeding occurs the surgeon should proceed to turn out the clot, securing dangerous points by ligature or the actual cautery, make the wound antiseptic, pack it, and wait for it to heal by granulation. Sponge grafting would probably hasten cicatrization by causing granulations to fill the cavity more promptly. The patient must be constantly watched by competent surgical attendants, so that on the first sign of bleeding the artery can be controlled by digital compression, or by screwing down the pad of the tourniquet, which is kept loosely applied. If hemorrhage per- sists, amputation should not be long delayed by experiments with tem- porizing measures. Gangrene of the limb is a formidable complication of ligation. Its occurrence may be due to rigidity of the arterial branches preventing sufficient enlargement for the establishment of collateral circulation, to pressure of the tumor upon the anastomosing branches, to injury of the main venous trunk at the time of ligating the artery, and to exposure of the limb to heat, cold, or undue pressure soon after the operation. This complication arises within the first week or ten days, and is more frequent in the lower than in the upper extremity. The form is generally that of moist gangrene because venous obstruction is usually one of the factors in its etiology. Wrapping the limb in cotton to keep the temperature equable and to avoid injury, and slightly elevating it to encourage venous return are measures calculated to lessen the probability of gangrene. Gentle friction of the limb toward the body may sometimes be used to accelerate the venous blood current. When gangrene has begun after arterial liga- tion, but little can be done except promptly to amputate the limb high up. In the upper extremity removal at the shoulder-joint, in the lower removal at the junction of the middle and upper thirds of the thigh will probably be necessary. Occasionally laying open the sac and turning out all clots will relieve venous obstruction and restrain the progress of gangrene. Gangrene of a similar character may follow the employment of com- pression for the cure of aneurism. Pyaemia may follow ligation, and is more frequent in patients who have previously suffered from hemorrhage or other depressing influences. Finally ligations of vessels near the body may be complicated with pleurisy, peritionitis, and other unfortunate sequences, due to injury at the time of operation, or to spreading of inflammation. The fatal issue after LIG ATION OF A R T E R I. A. L T R U N K. S. . 285 ligation of the common carotid artery may be due to cerebral anaemia or thrombosis. Suppuration and septicamic or sapraemic processes occurring in connec- tion with aneurism are, of course, due to the same vegetable parasites as cause these conditions in other surgical wounds or diseases. The bacteria either gain access by the wound made, or while circulating in the blood or lymph streams, are arrested and find a place of least resistance in the tissues where the aneurism exists. LIGATION OF ARTERIAL TRUNKS IN CONTINUITY. Arteries are tied in their continuity to lessen the circulation through aneurismal tumors and to arrest secondary hemorrhage, which pressure or ligation in the wound has failed to control. The special instruments required for the operation are a bistoury or scalpel, dissecting forceps, a grooved director, two metallic retractors with which to hold the margins of the incision apart, an aneurism needle, and a strong antiseptic ligature of catgut, ox-tendon, or nerve. FIG 112. *- sesssssssssssssssssss- Grooved director. FIG. I.13. | -------. Aneurism needle. FIG. 114. Blunt and sharp-pointed retractors. The surgeon must first of all determine the exact course of the artery by the well-known landmarks of clinical anatomy and the linear guides Which are based upon these relations. If the artery is a superficial one its pulsation will aid in this determination. If a superficial tendon or muscle is one of the guides, it can be made to stand out prominently by getting the patient, before etherization, to use it voluntarily. The line of the tendon or artery can then be marked on the skin with a moistened aniline pencil. In operating on the dead body such tendons are made Prominent by moving the joints in such a manner as to bring tension on 286 L) I SE A SES OF T H E A R T E R I E S. the muscular fibres. For example, if a flexor is the guide ask the patient to flew the joint, and the muscle will on contraction become prominent; but in the surgical laboratory the same muscle in the cadaver can only be rendered prominent by forcibly eatending the joint. The second step is to decide upon the point of ligation. In secondary hemorrhage it is the best, if practicable, to expose and tie the vessel near the wound and on both sides of it. In the case of aneurism the Hun- terian method is usually the best. This places the ligature sufficiently far from the aneurism to insure at least one small branch being given off by the trunk between the site of ligation and the aneurism. The ligature should always be applied at least one-half or three-quarters of an inch below the origin of any large branch or bifurcation of the artery. When this is anatomically impossible it is often wise to secure the branch also with a ligature to prevent secondary hemorrhage, which otherwise may result from the forcible collateral current developed in the branch or bi- furcation. The incision in most instances should be made slightly oblique to the course of the artery and with its centre over the point chosen for ligation. Such an obliquity of ten degrees makes it much more easy to search for the muscular interspaces and other deep guides leading to the vessel. The skin should be steadied, but not displaced, by the thumb and fingers of the left hand while the point of the knife is inserted perpendicularly through the skin and an incision varying from two to five inches in length is made with one sweep. The scalpel should be brought out per- pendicularly in order that the wound may be of one depth throughout its entire length. The incision should always be sufficiently long to afford free access to the tissues beneath. When the artery is deeply located, whether from its anatomical relations or the obesity of the patient, a long incision is demanded. The superficial fascia may be divided at the same time as the skin, if the vessel lies below the deep fascia. Large super- ficial veins should be drawn aside, if convenient, though their division is of little importance since the bleeding is easily arrested by hemostatic forceps or ligatures if it does not cease spontaneously. The deep fascia is to be incised in a similar manner as the skin, or it may be punctured and a grooved director slipped under it, after which manoeuvre it is divided by carrying the inverted knife along the groove. The original length of the incision should be maintained until the sheath of the artery is reached. If the deep fascia is so tense as to prevent satisfactory inves- tigation of the parts beneath, a short incision may be made across the middle of the longitudinal one. Muscular interspaces are guides to some of the arteries. These, on account of the fat deposited in them, are usually quite readily recognized as yellow lines. Sometimes this yellow appearance is seen before the deep fascia is divided. Another guide to them is furnished by the small vessels which ramify in them and perforate the fascia covering them. The proper muscular interspaces to gain access to the artery are next torn open with the rounded end of the director; or the wound is deepened by the careful use of the scalpel. As the situation of the artery is approached the forceps and the back of the scalpel's point are the safest means of separating the tissues. During this dissection the wound may be held open by blunt hooks or retractors, and the bulging muscles relaxed by bending the joints. The larger arteries, with the accompanying vein or veins, are enclosed in a distinct fibrous sheath. This sheath is to be opened by pinching up LIG ATION OF A R T E R I. A. L T R U N KS 287 a fold with small toothed forceps and making in it with the knife a cut about a quarter of an inch long. While the forceps holds the edge of the opening the end of the grooved director or aneurism needle is intro- duced into the sheath on one side of the artery and used to break up the adhesions between the vessel and the sheath, or the adjacent contents of the sheath. By a similar manoeuvre on the other side of the vessel com- plete isolation of the same is accomplished. ... Isolation of smaller arteries which have no distinct sheath can be readily performed by using two pairs of forceps to pull away the small veins and cellular tissue. . The use of the point of the knife is dangerous in cleaning the artery, lest a puncture be inflicted upon the artery or vein. Care must be observed with the blunt instruments that undue bruising is not done. The Esmarch apparatus is sometimes applied to prevent obscuration of the parts by hemorrhage during the operation. Usually it is unnecessary, for only a few small branches are divided. These can be tied, if necessary. It is well to remember the characteristics of an artery in the living subject. It has a pinkish-white, smooth, shining surface, and is compres- sible, feeling as it is rolled under the finger-tips as if two surfaces were slipping upon each other. A nerve has not this smooth, shining surface, but has longitudinal markings, due to its fibrous structure, and rolls under the fingers as a Solid non-compressible cord. A vein is purplish, soft, and flaccid, and from its distention with dark blood resembles a leech in appearance. It becomes more distended if pressure is made on its car- diac end. A small tendon is pearly white and glistening, and gives, when seized, the impression of great density. Passive motion of the neighbor- ing joint may prove its identity. The recognition of the artery is often aided by its location between two satellite veins and by its pulsation. Pulsation, however, may be absent, because exposure and manipulation sometimes cause arteries to contract and become temporarily pulseless. On the other hand, a deceptive pulsation may be transmitted to nervous or fascial bands lying over an artery. When the operator fails to find the artery he should not tear up the tissue in an aimless manner, but should at once review all the steps of the operation and systematically verify each landmark from the surface downward. In this way he will discover the source of error. After the artery has been recognized and isolated the end of the curved aneurism needle, threaded with antiseptic catgut or silk is carefully passed around it without disturbing its surroundings or pulling it from its bed. Chromicized gut is better for large vessels than plain gut since it is not so quickly absorbed. This is best done by grasping the tissues at one side of the artery, but not the artery itself, with the forceps and insinuating the aneurism needle with a curvilinear movement under the artery from that side. A little lateral movement of the point of the needle will render its passage more easy. As the point projects at the opposite side of the vessel the tissue overlying it may be torn through with the finger- nail or forceps, if it is seen not to be a vein or part of the arterial wall. When the loop of ligature in the eye of the needle is visible it is drawn out of the wound by the forceps while the needle is made to retrace its Course under the vessel and is thus removed. If the artery has a single vein alongside of it the needle should be in- troduced at the venous side of the artery, since puncture of the thin- Walled veins is thus less likely to occur than when the point of the needle is carried beneath the vessel from the side opposite to the vein. If accom- Panying veins exist on both sides of the artery this precaution loses its 288 D IS E A SES OF T H E A R T E R I E S. value. If by accident such a large vein is punctured during the opera- tion, it may be well to extend the incision and tie at a higher point of the artery. Bleeding from the vein is to be controlled by lateral ligation or suture of the vein, if any venous hemorrhage of importance occurs. Be- fore tying the ligature the surgeon should hold the artery in the loop of the string and compress it with a finger to be sure that pulsation below is arrested by constriction of the structure encircled. This manoeuvre proves FIG, 115. §º * j \º | Diagram of opening sheath of artery, passing ligature and tying ligature. (BRY ANT.) or disproves the proper application of the ligature, which may be around the wrong artery or perchance around a nerve or piece of fascia. The ligature should be secured by a friction knot or a flat knot; and in the latter case it is well to tie the ends a third time after completing the ordinary double tie, for the catgut is apt to become loosened. During the knotting the index fingers should be carried into the depth of the wound in order not to raise the vessel from its bed. Sufficient tension should be put upon the first tie to insure division of the inner and middle coats of the artery. This is known by the sensation of cutting into the wall that is felt by the operator as the noose is tightened. When mere approxima- tion of the inner tissue is desired, this cutting is avoided by using flat liga- tures of ox aorta or nerve. After ligation is accomplished the wound is approximated with sutures, cotton is applied around the limb to maintain an equable temperature, and the extremity is slightly raised to encourage venous return. The wound must be kept bacteria-free so that septic and purulent infection may be with certainty avoided. LIGATIONS OF SPECIAL ARTERIES. Certain of the arteries are ligated in continuity with comparative fre- quency. The most eligible site for such ligations must be mentioned and the successive steps described. The unusual operations will be omitted. H. R. A. C. H. I. A. L. A R T E R Y . 289 RADIAL AND ULNAR ARTERIES.—These vessels are seldom tied, except at the wrist. If deligation at a higher point of either artery is demanded, the surgeon usually prefers to secure the brachial. The radial artery above the wrist lies between the tendons of the radial flexor of the carpus and the long supinator, immediately below the deep fascia, and upon the square pronator. Its direction and site are indicated by a line drawn from the middle of the bend of the elbow to the inner side of the styloid process of the radius. An incision one and a half to two inches in length midway between and parallel to the radial flexor and the long supinator will expose the vessel with its satellite veins. The deep fascia must be divided with care or the artery may be wounded. The pulsation of the artery is readily felt before the skin is incised. , FIG. 116. Deehſascia \ – - º > • * :-- Ligation of radial and ulnar artery. (BRYANT.) The ulnar artery at the wrist lies under the radial border of the tendon of the ulnar flexor of the carpus and between it and the superficial flexor of the fingers. The vessel lies under a layer of fascia situated below the tendon; hence, it is necessary to divide two layers of deep fascia before reaching it. The ulnar nerve is situated at the ulnar side of the artery and close to it. The course of the lower portion of this artery is indi- cated by a line drawn from the inner condyle of the humerus to the radial side of the pisiform bone. The surgeon may depend upon this line for determining his incision, or may recognize the position of the tendon of the ulnar flexor of the carpus by its insertion into the pisiform bone, and make an incision of one and a half or two inches along its radial margin. The glistening tendon, uncovered after dividing the deep fascia, should be drawn from the middle line of the arm, when the second pro- cess of deep fascia will be exposed. This must be opened before the artery is reached unless it has an anomalous course above the fascia. It is usual to pass the aneurism needle first between the artery and the nerve. BRACHIAL ARTERY.—The brachial artery in the middle of the arm lies along the inner border of the biceps; and upon the coraco-brachial, the anterior-brachial muscles, and the inner head of the triceps. The median nerve passes over it, though occasionally under it, from without inward. A satellite vein is to be seen on each side of the vessel, and the large, basilic vein not far distant internally. A line, drawn from the junction of the anterior and middle thirds of the axilla to the middle of the bend of the elbow, indicates its course with accuracy. Its pulsation is easily felt. An incision two and one-half or three inches in length is to be made along the inner side of the biceps; when the deep fascia has been divided, the muscular fibres of its margin will be fully exposed. Alongside of or under the edge of this muscle will be seen the median 19 290 D IS E A SES OF THE A R T E RIES. merve, which is then drawn aside to reveal the artery lying beneath it. The nerve often shows marked transmitted pulsation. Sometimes the artery is more superficial than the nerve. The arm should at this stage be flexed at the elbow to relax the belly of the biceps. It is usually better to have an assistant hold the arm than to allow it to lie upon the table, because such pressure displaces the artery and pushes up the triceps, which may be mistaken for the biceps. The edge of the biceps should always be uncovered and identified; if it is not, the surgeon may work too far inward and backward and become confused by mistaking the ulnar nerve for the median, and the basilic vein for the artery. The vessel is to be sought at or under the edge of the biceps in an outward rather than an inward direction. FIG. 117. Bicyes Žtas cle §§º)\\ * : * * i l & I -Mºdiaz'zeroe Tendinous Ahoneurosis divided _` f - / ſ ,” Ligation of brachial artery. (BRY ANT.) Since the brachial artery is not infrequently double or perhaps bifur- cates into the radial and ulnar up near the axilla, it is important that the surgeon remember this possible anomaly, and ascertain that he has secured that vessel which will diminish the blood-supply as he desires. AxILLARY ARTERY.—The third portion of this vessel can be reached with safety and ease. If ligation at a higher point is demanded by the exigencies of the disease, it is better perhaps to secure the third portion of the subclavian than to attempt ligating the first or second portion of the axillary. - The last, or third portion of the axillary artery, beginning at the lower edge of the lesser pectoral muscle, lies along the inner border of the coraco-brachial muscle. The median and musculo-cutaneous nerves lie on the outer side of the artery; the ulnar and internal cutaneous nerves and the axillary vein on the inner side. Sometimes there is a satellite S U B C L A VI A N A R T E R Y . 291 vein on each side of the artery instead of the single large axillary vein on its inner side, which is replaced by the continuance upward of the basilic vein. A line drawn from the junction of the anterior and middle third of the axillary fossa to the middle of the bend of the elbow, gives the course of this portion of the axillary and the greater portion of the brachial artery.

(BRYANT.), When the arm is placed at a right angle with the body the muscular margins of the axillary pit are prominently shown. With the limb in this position an incision three or three and one-half inches long should be made parallel to the anterior boundary of the axilla, and about one third the width of the axillary space behind this boundary; or, in other words, directly over the head of the humerus and a little oblique to the line given above. The edge of the coraco-brachial muscle will be exposed. From this the operator searches in an inward direction, finding, first the median and perhaps the musculo-cutaneous nerves, and then the artery, with the axillary vein, the ulnar and internal cutaneous nerves on the inner side. The nerves, which wary somewhat in their relations, may be mistaken for the artery. Occasionally a muscular slip from the broad dorsal muscle crosses the artery. It is recognized by the transverse direction of its fibres. The ligature must be passed from within outward, and should not be applied near the origin of the subscapular artery. SUBCLAVIAN ARTERY.—The third portion of this artery extends from the outer margin of the anterior scalene muscle to the outer or lower border of the first rib, and is the only part of the vessel that can be ligated with comparative safety. It is situated in the triangle bounded by the clavicle and the sterno-mastoid and omo-hyoid muscles; lying against the first rib, the anterior scalene muscle and brachial plexus of nerves. The subclavian vein is situated below and in front of the artery, from which it is separated by the insertion of the anterior scalene muscle intº the tubercle of the first rib. To ligate the artery in its third position proceed as follows: Depress the patient's shoulder, turn his head in the opposite direction, and draw the skin of the supraclavicular fossa downward upon the clavicle with 292 D IS E A SES OF T H E A R T E R IE S. the left hand and hold it there. Then make an incision, three or four inches in length, upon the clavicle and following its curves, beginning a half inch from the sterno-clavicular joint. The tissues should be divided down to the periosteum. When the left hand has released its traction, the skin will slide upward and the incision will be located about half an inch above the clavicle. This manipulation of the skin preserves the external jugular vein from division by the incision. The wound should now be deepened by dividing the deep fascia and cutting the edges of the sterno-mastoid and trapezius muscles, if they prevent the wound being continued deeper with its original length. The fibres of the platysma myoid muscle in the superficial fascia will be noticed during the dissec- tion. If the external jugular vein cannot be held out of the way with a hook, it is to be divided. A ligature should be placed also at the cardiac side Óf the proposed section before the division is made, lest air be sucked into the heart. As the wound is carefully deepened the surgeon's finger seeks, at its inner corner, the edge of the anterior scalene muscle as it goes down to its insertion into the first rib. The tubercle of insertion is often poorly developed, but the direction of the fibres, and possibly the ex- posure of the phrenic nerve running obliquely over the muscle, will serve to differentiate it from other structures.

The artery is finally uncovered beyond the outer border of the anterior scalene by opening with the foll- ceps or director a layer of fascia extending over the vessel from this muscle. The artery lies at a depth of from one to three inches from the surface and runs in a downward and outward direction almost in the axis of the arm. The aneurism needle should be passed from above down- ward, because there is more danger of encircling the nearest cord of the brachial plexus than of injuring the vein which lies at some distance from the artery, though below it. This is an exception to the axiom which C O M M O N C A R O TI D A R T E R Y . 293 directs the needle to be passed, as a rule, first between the vein and the artery about to be ligated. The chief errors to be avoided in the operation are injury to the veins and ligature of that portion of the brachial plexus. During the dissection the suprascapular artery or the transverse artery of the neck, may be divided and require ligation. COMMON CAROTID ARTERY.—The direction of the common carotid and its continuation, the internal carotid artery, corresponds with a line drawn from the sterno-clavicular joint to the tragus of the ear. The com- mon carotid artery extends only to the level of the top of the larynx, where it bifurcates into the external and internal carotid arteries. The left carotid has its origin lower than the sterno-clavicular articulation, but in this intrathoracal portion of the artery surgeons have little interest. This circumstance, however, renders ligation of the carotid below the omo- hyoid muscle safer on the left than on the right side; because the ligature is further from the blood stream in the parent vessel. The external carotid at its origin lies from a quarter to a half inch nearer the middle line of the neck than the line given for the internal carotid. The common carotid artery lies beneath the anterior edge of the sterno- mastoid muscle in a sheath, which also encloses the internal jugular vein and the pneumogastric nerve. The vein lies on the outer side of the artery, the nerve lies behind both and in the groove between them. The descending branch of the hypoglossal nerve forms a loop with branches from the cervical plexus usually upon the front of, but sometimes within, the sheath. The artery becomes more and more superficial as it ascends. Its sheath is crossed by the omo-hyoid muscle about midway between the sterno-clavicular joint and the top of the larynx; or, in other words, at the level of the cricoid cartilage. For ligation of the common carotid the patient's head should be thrown well back, with the chin turned toward the opposite side. A small pillow or roll of cloth under the nape of the neck enables the surgeon to keep the patient in this posture. An incision of two and a half or three inches with its centre corresponding to the level of the cricoid cartilage should be made along the anterior edge of the sterno-mastoid muscle. When the fascia and the platysma-myoid muscles have been divided and the fibres of the sterno-mastoid become visible by the dissection, the margin of the latter muscle must be turned outward and the angle between it and the 9mo-hyoid muscle, with its obliquely ascending fibres, found. If the omo- hyoid is pulled inward and the sterno-mastoid outward, the sheath of the artery, with very possibly the descending branch of the hypoglossal nerve upon it, will be seen. The sheath will also be recognized by its slipping sideways between the finger and the vertebrae behind, and by the pulsating Vessel within it. The external and anterior jugular veins should be drawn aside, if in the line of the dissection. When this cannot be done, they may be tied and divided. The sheath is then opened toward the tracheal side Of the artery, which is isolated with care, and the needle passed from with- ºut in Ward, in order to avoid injury to the internal jugular vein lying on the outer side of the artery. This operation ties the common carotid *y just above the omo-hyoid muscle, which is the better situation for application of a ligature. º: º below the omo-hyoid, make a three-inch long incision just in e anterior margin of the lower third of the sterno-mastoid muscle. Detach the inner portion of the muscle from the clavicle and turn it outward. The Omo-hyoid and the sterno-hyoid muscles will thus 294 D IS E A SES OF T H E A R T E R IF. S. be exposed. These are to be pulled apart by hooks, when between and below them will be seen bulging upward the sterno-thyroid muscle. The finger thrust down between the lower part of the omo-hyoid and the sterno- thyroid, which is on a lower plane, will feel the artery beating in its sheath. FIG.

It may be necessary to incise the sterno-thyroid in order to expose fully the sheath, which is then opened and the aneurism needle passed around the artery from without inward. In both operations the branch of the hypoglossal nerve should be protected from injury as much as possible. INTERNAL AND ExTERNAL CAROTID ARTERIES.—The common caro- tid artery should not be tied for a lesion of the external carotid or its branches when there is room between the bifurcation of the common trunk and the lesion to allow the safe application of a ligature to the external carotid. Ligation of the internal carotid should be performed in many conditions which formerly have been treated by tying the com- mon carotid trunk." For ligating the internal carotid an incision two and a half inches long with its centre about half an inch above the upper border of the larynx, should be made a little oblique to a line drawn from the sterno-clavicular joint to the tragus of the ear. The vessel will be found along the edge of the sterno-mastoid muscle. The hypoglossal nerve crosses the vessel about an inch above its origin, and the descending branch of the same nerve will probably be found running down the artery. The hypoglossal nerve 1 See Dr. John A. Wyeth’s Prize Essay on- this subject. Trans. American Med. Asso- ciation, 1878. * POST E R I O R TIB [A L A R T E R Y . 295 and the digastric muscle, which also crosses the artery, should be drawn upward and the ligature passed from without inward, avoiding constric- tion of the internal jugular vein and the pneumogastric nerve on the outer side, the external carotid on the inner side and the hypoglossal nerve superficially. The external carotid, which also is crossed by the hypoglossal nerve and digastric muscle, may be tied by a similar incision, but it must be remembered that this artery is placed a little nearer the middle line of the neck than the internal carotid. If a large branch is given off near the point of ligation, it also should be tied. ANTERIOR TIBIAL ARTERY.—A line drawn down the front of the leg from the inner side of the head of the fibula to a point midway be- tween the two malleolar prominences marks the direction of the anterior tibial artery. The vessel, throughout its course, lies along the outer margin of the anterior tibial muscle. It is deeply placed upon the front of the interOsseous membrane, at its upper part; but it gradually becomes superficial as it descends to the ankle, where it is found immediately under the deep fascia. It can be quite readily tied in its middle third by an incision, three inches long, made a little obliquely to the line given above. The operator, before incising the deep fascia, can usually define the inter- muscular space bounding the outer border of the anterior tibial muscle, by a yellowish-white line of fat showing through the deep fascia. The deep fascia should be divided just as the skin and superficial fascia have been ; after FIG. 121. which the space between the anterior tibial muscle and the long extensor of the toes should be torn open with the finger or end of the grooved director. This procedure will expose a third muscle, the extensor of the great toe, lying between the two just mentioned and at a lower level. Search in the bottom of the fissure between this extensor of the great toe and the anterior tibial muscle will reveal the artery, with the an- terior tibial nerve lying to the outer side or a little in front. It is possible that the ex- tensor of the great toe may have its origin Ligation of anterior tibial artery. from the fibula lower than usual, then the (SMITH.) Vessel will be found in the same manner, but between the anterior tibial muscle and the long extensor of the toes. The operator must remember to keep close to the outer margin of the anterior tibial muscle. If he mistakes the proper intermuscular space he Will fail to reach the vessel. Passive motion of the great toe, of the smaller toes, and of the ankle joint will enable him to distinguish the Various muscular bellies in the wound. PošTERIOR TIBIAL ARTERY.—The course of this artery is indicated by a line drawn from the middle of the popliteal space to a point midway. between the tip of the inner malleolus and the anterior border of the *ndon of Achilles. The vessel, when it gets behind the inner malleolus 9turves forward and goes to the sole of the foot. Behind the malleolus it * Covered only by the skin and the superficial and deep fascias.

A single large nerve, the posterior tibial, is usually found on the posterior or heel side of the artery; sometimes there are two small nerves, one on each side. The tendons of the posterior tibial muscle and long flexor of the toes lie in front of the artery—that is, nearer the malle- olus; the tendon of the long flexor of the great toe behind it and deeper. Occasionally the artery bifurcates into the two plantar arteries before reaching the sole; in such a case the two vessels may be tied. FIG.

In the middle of the leg the posterio-tibial artery lies beneath the gas- trocnemius and soleus muscles and upon the posterior tibial muscle and the long flexor of the toes. It is separated from the soleus by a septum of the deep fascia and has the posterior tibial nerve lying on the outer or fibula side. The artery can be ligated from the side of the calf as fol- lows: Lay the leg on its outer aspect with the knee flexed and the heel raised to relax the calf muscles. Make an incision of four or five inches, parallel to and half an inch behind the inner margin of the tibia. If the gastrocnemius is seen, draw it away from the tibia and expose the soleus; if it is not seen, the soleus will be exposed at once. The soleus is then to be cut from its attachment to the tibia by carrying the knife, with its edge directed against the bone, along the entire length of the cutaneous incision. By drawing the cut muscle outward the surgeon will uncover the septum of deep fascia that lies over the artery. The vessel can be seen or felt beneath this fascia about an inch from the edge of the tibia and is readily uncovered by incising the fascia, which may be thick, with the knife. The operator may mistake the gastrocnemius for the soleus because the incision was made too far from the tibia, or he may cut too close to the tibia and, therefore, fail to recognize the soleus and, as a result separate not only it but the deeper muscles from the tibia and get down to the interosseous membrane. The knife should be held with its edge toward the bone in order not to make an oblique section of the soleus. There is an intramuscular septum in the middle of the soleus which is parallel to the septum of deep fascia under which the artery lies. This may mislead the surgeon, who will EXT E R N A L A N D C O M M ON I L I A C A R T E R IE S. 297 think he has cut entirely through the muscle when he has only gone half- Wà.W. Feworx, ARTERY.—The common femoral artery and the upper part of its continuation, the superficial femoral, have their course indicated by a line drawn from a point mid- way between the anterior superior FIG. I 23. spine of the ilium and the sym- physis of the pubes, where the pulsation can always be felt, to the prominence of the internal . . . . . condyle of the femur. This line " ,---- -- bisects Scarpa's triangle, running from the centre of the base |º through its apex. Scarpa's tri- , ...)—º angle is bounded by Poupart's 6 - *NSY ligament above, the Sartorius muscle externally, and the long adductor muscle internally. The t apex of the triangle at the point Ligation of femoral artery. (SMITH). of junction of these muscles is on the inner side of the thigh. The vein corresponding with the arteries lies upon their inner side except near the apex of Scarpa's triangle, where it passes behind the artery, and finally gets to the outer side. The ante- rior crural nerve is on the outside of the arteries, and at a distance, except near the apex of the triangle, where one of its branches lies close to the vessel. It is well to remember that in fat persons the fold of the groin is a little below Poupart's ligament, and does not, as in lean patients, correspond with the ligaments. The superficial femoral artery is to be ligated where it is crossed by the Sartorius muscle at the apex of Scarpa's triangle, which is about four inches below Poupart's ligament. The thigh should be everted and an incision three or four inches long made at this point, a little oblique to the line of the artery, avoiding the internal saphenous vein. When the inner border of the sartorius is recognized by its fibres passing obliquely downward and inward, the proper landmark or guide has been found. The edge of this muscle should be turned up and under it will be discov- ered the sheath of the artery, running in the direction indicated by the line already mentioned. The vein will probably be a little behind the artery, though on its inner side. The ligature should be passed from Within outward. The artery is so superficial that its pulsation can usually be felt through the tissues before the first incision is made. The common femoral artery is readily secured by making an incision two inches long parallel to Poupart's ligament, and a half inch below its Centre. . Some lymphatic glands may require pushing aside when the Superficial fascia is being divided; after which incision of the deep fascia Will disclose the sheath of the artery. The vein is on the inner side of the artery, hence the ligature should be carried around from the inner side. ExtERNAL AND CoMMON ILIAC ARTERIES.—The course of the com- Ill Oll iliac artery and its direct continuation, the external iliac, is indicated by a line drawn from the left side of the umbilicus, on a level with the top of the iliac crest, to a point midway between the anterior superior Špine of the ilium and the symphysis of the pubes. The upper third of this line corresponds with the common, the lower two-thirds with the °xternal iliac ; though this proportion often varies, because the bifurca- 298 D IS E A SES OF T H E A R T E R IB S. tion of the common trunk into external and internal iliac varies in location. The common iliac has the peritoneum just in front of it and is crossed at its lower end, near the point of bifurcation, by the ureter. The rectum as it descends into the pelvis also crosses the left artery. The lower part of the common and the entire length of the external iliac lie along the inner border of the great psoas muscle. The common iliac vein on the left side of the body lies at the inner side of the artery; on the right side it is behind the artery at its lower part, and on the other side above. This may be memorized by the fact that each common iliac vein lies on the right side of the corresponding artery. The external iliac arteries are covered by the peritoneum, and have the veins lying internally and the genital branch of the genito-crural nerve lying externally. Near Poupart's ligament the external iliac is crossed by the was deferens and the spermatic vessels, and gives off two branches. It must not be tied here. The external iliac artery is reached for ligation by a crescentic inci- sion of four or five inches in length, with its convexity downward, begin- ning an inch above and an inch outside of the middle of Poupart's ligament, and ending at a point an inch above the anterior superior iliac spine. This will probably cut the superficial epigastric artery, which will require tying. The tendon of the external oblique muscle, which is ex- posed, must be divided to the same extent as the skin, either with the knife's edge held perpendicular to its surface, or upon a director. FIG. 124. Lines of incision for (A) common iliac, (B) external iliac, (C) femoral arteries. (STIMson.) The fibres of the internal oblique and transversalis muscles must be divided in the same way.

The operator with his finger loosens this serous membrane from the front of the iliac fossa and vessels; beginning at the external end of the wound, where the attachment is least strong.

Ligation of external iliac and femoral arteries. (BRY ANT.) The assistant, who, during the incision was pressing on the belly wall to make the muscles tense, now puts a broad spatula into the wound and draws the peritoneum inward. - . The artery and vein in a sheath of fascia will now be felt along the inner border of the belly of the psoas. After the sheath has been Opened, the aneurism needle is carried around from within outward. The incision given should be carefully followed as to length and curve through its entire depth. It should not go nearer the middle line lest it cut into the external abdominal ring, nor lower, lest it open the inguinal canal or cut the deep circumflex iliac artery. When the director is pushed under the tissues it should be kept longitudinal, so as not to puncture deeper layers unawares. It is wise not to incise all the way to its end, lest the peritoneum be folded over the extremity and thereby be wounded. 300 D IS E A SES OF T H E A R T E R IB S. The common iliac artery can be reached by an incision similar to that used for the external iliac, but beginning an inch higher and extending about two inches further upward toward the last rib. The muscles and transversalis fascia are divided in the same manner as just described. When the peritoneum is pushed inward the ureter and spermatic vessels are carried with it, as they adhere to its outer surface. The artery can then be felt near the promontory of the sacrum. The needle should be carried from right to left on each side of the body, as the vein lies to the right of the artery in each instance. The ureter might be tied instead of the artery if the operator is not careful, and in case of high bifurcation of the common iliac the ligature might in error be applied to the external iliac artery. INTERNAL ILIAC ARTERY.—This vessel extends from the bifurcation of the common iliac at the Sacro-iliac junction to the top of the great sacro-sciatic foramen with the ureter and peritoneum in front, its vein and the sacral plexus of nerves behind. It is ligated by an incision sim- ilar to that for tying the common iliac. These methods of reaching the common and internal iliac arteries are somewhat complicated and difficult because of the great depth of the wound. It is a question whether a laparotomy in one of the semilunar lines with ligation of the vessel through the peritoneum is not simpler, and therefore easier and safer. ARTERIAL VARIX OR VARICOSE ARTERIES. Arteries may become dilated and elongated, presenting a condition similar to varicose veins. The term arterial varix is generally applied to such a pathological change if the artery affected be a large vessel, such as the temporal, facial, or iliac, while to similar dilatation of the terminal subcutaneous arterioles of a normal diameter of about one-fiftieth of an inch the term cirsoid aneurism has been applied. I shall discard the latter name, since the condition has no pathological resemblance to aneurism, and use the term arterial varix, or varicose artery, for dilata- tion and elongation of prečacisting ar- teries of any size, provided their pre- existence can be demonstrated clinic- ally or microscopically. When there is a development of new vessels with arterial characteristics, it is proper to call the mass or tumor an arterial angeioma. It may at times be diffi- - cult to determine clinically whether Arterial varix of the palm and fingers. the pulsating growth is composed (AGNEw.) principally of new vessels or prečx- isting ones. A varicose artery in addition to being generally dilated, may show irregular pouches or sacculations. The middle tunic especially is thinned A. R. T E R I A. L. W. A. R. I X O R. W. A. R. I. C. OS E A R T E R I E S. 301 until the artery looks like a vein ; hence the blood current may become very sluggish. The cause of the change is probably some obscure vaso- motor disturbance leading to loss of muscular tone in the middle coat. Atheroma seems not to be a factor in the causation. Arterial varix is exhibited as a pulsating tumor with an irregular, nodulated surface, which usually shows the position beneath the skin of the dilated arteries. When the hand is applied to the tumor a vi- bratory thrill is felt that in some cases resembles the wriggling of a mass of worms. Pulsation may be distinct and is more general than the limited pulsation felt in aneurismal varix or arterio-venous fistula between vein and artery. Auscultation reveals a blowing or cooing murmur. Pressure upon the afferent artery stops all movement and murmur. If there are several arteries, pressure on one merely dimin- ishes these signs. When the disease affects a number of small arterioles the tumor has a spongy feel, and the outline of the vessels is not traceable through the skin. If an arterial varix shows no tendency to increase in bulk, and is not threatening hemorrhage from inflammatory and ulcera- tive processes, it should be let alone. If treatment is demanded, excision or ligation should be done in the manner described in the section which discusses angeiomas. This is better, and probably safer, than injection with coagulating fluids. C H A P T E R X W II. DISEASES AND INJURIES OF BONES. PERIOSTITIS. CAUSES.—Periostitis, or inflammation of the fibrous membrane cover- ing the exterior of bones, is caused by injuries, such as contusions, and by certain constitutional conditions, such as rheumatism, gout, and especially syphilis. Agnew believes that it may be due to violent traction of muscles inserted into the periosteum. The vessels of the periosteum, of the bone, and of the medulla are continuous through the ramifications of Haver- sian canals and spaces. Hence, inflammation of one of these structures is usually associated with inflammation of the other in the same locality. As ostitis is really an inflammation of the medulla within the bone spaces, it may be the cause of periostitis, and periostitis may similarly be the cause of ostitis or of myelitis. PATHOLOGY..—The pathological changes seen in periostitis are conges- tion, thickening, and softening of the membrane due to rapid cell-prolifera- tion and accumulation of the wandering blood cells. The deepest layer of the membrane, which is that which causes bone growth, is especially active in cell formation ; hence, the membrane is raised from the bone by a subjacent exudate and becomes easily detachable. The bone imme- diately beneath the inflamed area also becomes inflamed and softened to a limited extent. If resolution occurs, this exudate is absorbed, and the elevation, or node, caused by the cells and fluid beneath the periosteum disappears. At other times, the inflammation does not subside so easily ; this new material becomes organized into bone, and there is left a per- manent change in the contour of the skeleton. The entire bone may be enlarged if the periostitis is wide-spread. Flattened bony elevations or modes are of frequent occurrence after syphilitic periostitis, and often aid in establishing the constitutional causation of later obscure lesions in other parts and tissues. In periostitis, if pyogenic bacteria be present, suppuration may take place between the membrane and bone, giving rise to subperiosteal abscess, also called cortical osteomyelitis, and secondarily causing superficial necrosis of the bone in the vicinity. Periostitis of syphilitic origin occurring in the later stages of this constitutional disease is more prone to suppuration than when it occurs earlier. In diffuse Sup- purative periostitis the membrane is separated from a large surface of bone, and the vessels going to the bone are injured and stretched and be- come the seat of thrombosis. The surface of the bone, therefore, becomes necrotic. If there is concurrent suppurative inflammation of the marrow in the medullary canal, which is not infrequently the case, the necrosis will involve the entire thickness of the bone and not merely the Outer surface. Death from pyaemia may occur in such conditions. Subperi: osteal hemorrhages are sometimes found. This bleeding may be mechanical and due to forcible and rapid dissection of the membrane from the bone by the sudden inflammatory exudation. Acute infective periostitis is a P E RIO STITIS. 303 variety of suppurative periostitis and is liable to be followed by septi- caemia or pyaemia. It is usually associated with acute infective Osteo- myelitis, and is, of course, due to bacteria, probably the bacteria of or- dinary suppuration. SYMPTOMS.–The symptoms of circumscribed periostitis, which is by far the most common form, are pain, often worse at night, tenderness on pressure, heat of the surface, circumscribed swelling and, perhaps, local oedema. Persons whose occupations require them to work at night and sleep in daytime may have more pain during the day than at night. The deposition beneath the membrane may cause the parts to feel baggy or puffy on strong pressure with the fingers. The swelling has not abrupt edges, but gradually reaches the level of the surrounding surface. The pain is often excruciatingly severe and of a throbbing character. Red- ness of the surface occurs late and sometimes at no time during the pro- gress of the inflammation. The tibia, clavicle, ulna, and cranial bones are very frequently the subjects of syphilitic periostitis. Diffuse perios- titis, which is probably usually infective, is very rapid in its course, while the circumscribed variety is often a disease of slow development and progress. The former attacks particularly the long bones of tuberculous persons in early life, and is accompanied by violent constitutional dis- turbance. In this violent periosteal lesion chills, high fever, and delirium occur, and are accompanied by rapidly-spreading inflammation of the limb, which is shown by great pain, swelling, Oedema, and enlarged veins from obstruction to deep circulation. Ostitis, endositis, epiphysitis, and even arthritis often follow in its train. Death from septicæmia or pyaemia is not uncommon. Diffuse suppurative periostitis of the digital phalanges is often called whitlow or felon. The diagnosis of circumscribed periostitis is easy. It is usually syphil- itic when not traumatic. The diffuse or suppurative form may be mis- taken for diffuse cellulitis, but, as a rule, it does not extend beyond the joints at the extremities of the bone affected. Suppurative cellulitis fre- quently passes beyond joints. From rheumatism, periostitis is dis- criminated by the swelling, which is not apt to be situated at the joints, and by the evidences of suppuration in the purulent form of periostitis. Acute infective periostitis is often mistaken for rheumatism, and must be remembered as a possibility when such violent general symptoms, in young persons, are associated with pain about the tibia and femur. TREATMENT.-The treatment of acute periostitis of a sthenic type should consist of cathartics and diaphoretics combined with anodynes. The asthenic cases demand iron, quinine, and stimulants with concen- trated food and anodynes. Locally, leeches, lead water and laudanum, and moist antiseptic dressings should be employed in the acute form ; tincture of iodine and blisters in the more chronic cases. As syphilis is probably the commonest cause of non-traumatic periostitis full doses of iodide of potassium should be administered. The dose should not be less than 10 grains three times a day after meals, and may be increased to 30 or 40 grains in a rebellious case. As this lesion is a manifestation of the later stages of syphilis, the iodides are possibly more efficacious than mercury. The two remedies may be combined. The pain of syphilitic periostitis, often called syphilitic neuralgia, can fre- Quently be promptly cured by these large doses of potassium iodide. When the pain of periostitis of any origin does not promptly subside, free incision of the tense fibrous periosteum is the proper surgical remedy. The tension due to the subperiosteal exudation is thus removed, and as a 304 D IS E A SES A N D IN J U R IF S OF B O N E S. consequence pain is relieved, resolution favored, and the danger of sec- ondary necrosis lessened. In non-suppurative cases the incision is to be done subcutaneously by passing a tenotome through the skin in one or more places and incising the periosteum freely and deeply in every direc- tion by pushing the knife as far under the tissues as the handle will allow. In suppurative periostitis free incision must at once be made through the skin and other tissues directly down to the bone. If the bone becomes necrotic notwithstanding this line of treatment, it should be removed as soon as the patient can bear the shock. Some reproduction of bone may subsequently take place from the shreds of the periosteum not destroyed by the violent inflammation and from the medullary tissue in the inter- stices of the living bone. If great destruction occurs from involvement of the medullary membrane and the joints amputation may be demanded. OSTITIS OR OSTEOMYELITIS. CAUSES.— Ostitis or osteomyelitis may arise from contusions of bone, fractures, amputations, and other injuries, and from various constitutional deteriorations and mycotic affections such as rheumatism, syphilis, tuber- culosis, and low fevers. PATHOLOGY..—Inflammation of bone is pathologically identical with inflammation of the soft tissues, for it is the soft or animal tissue in the Haversian spaces, canaliculi, and lacunae of the bone that undergoes the morbid process. The earthy constituents cannot inflame; they only show the impress of the alterations induced in the vascular and other living tissues. When the inflammation affects the soft structures within the spaces mentioned the term ostitis is used; when the marrow in the medul- lary canal is the seat of these changes the term myelitis or endostitis is used. As ostitis is usually, if not always, associated with myelitis, sur- geons now use the word osteomyelitis almost exclusively, having dropped to a great extent the word Ostitis, except when speaking of chronic in- flammations, when ostitis is still used to some extent. The increased vascularity of inflammation is followed by softening of the bone, due to absorption of the earthy structures and the filling of the vascular canals and spaces with embryonic cells and migrating blood corpuscles. The coalescence of numerous canals and spaces by the ab- sorptive process exerted on their walls, makes the bone much more porous, while the increase in cellular elements gives it a soft and spongy charac- ter. This process has been called “rarefying ostitis,” or “dry caries,” because the bone is eaten away as if ulcerated, but without any pus for- mation. Changes in shape of long bones or vertebrae, due to this process, occur, hence the name “deforming ostitis.” This is the change that occurs when aneurisms cause absorption of the bone, when sequestrae are loosened, and when the ends of broken bones are rounded off. The inflam- matory cellular infiltration or exudate may be absorbed and the ostitis may thus be terminated by resolution without leaving permanent change. This is possible only in the early stages, or in a very mild degree of in- flammation. More frequently the cells become converted into Osseous tissue, which, though formed in the widened Haversian canals and medullary spaces, encroaches upon the calibre of these channels so much that they become smaller than they were originally. Thus the bone becomes harder, more compact or ivory-like, and, as a consequence, heavier than it was previous OSTITIS OR O S T E O MY E LITIS. 305 to the occurrence of ostitis. This is the pathological nature of most cases of chronic ostitis. As enlargement takes place both in diameter and length during the stage of softening and Swelling because of the coincident perios- titis and epiphysitis, an inflamed bone which is thus sclerosed becomes of greater bulk as well as harder than it was previously. This sclerosis or * condensing ostitis” may be found accompanying “rarefying ostitis” in the same specimen. The osteomyelitic inflammation may terminate in softening and degen- eration which will cause the so-called “cold * or “chronic abscess” of bone. The puriform fluid contained in such cavities is not true pus. It is well to remember that such abscesses are probably always due to the tubercle bacillus. When they occur in syphilitic persons it is possible that the syphilitic taint favors infection with the tubercle bacillus. Pus from inflamed bone contains oil globules in considerable numbers and is due to infection from pus bacteria. Septic osteomyelitis is then the con- dition. This last process is acute. Ulceration of bone, termed caries, and mortification of bone, called necrosis, may follow ostitis. The various stages and results of ostitis may often be found in different parts of the same bone. When repair takes place after deforming ostitis, tubercular ostitis or traumatic ostitis after fractures, the process is one of Ossification of granulation tissue which fills in the gap. It is simply a bony trans- formation of scar tissue. This process is well shown in some cases of curvature of the spine cured without the formation of puriform discharge. Acute inflammation of the bone and marrow may be traumatic; or it may occur without visible injury, and is then called spontaneous osteo- myelitis. In the latter case it is usually diffuse; in the former case it may be diffuse, but frequently is not so. In acute diffuse osteo-myelitis the marrow is injected and swollen, purple or marked with red, yellow, and purplish streaks, and protrudes in a fungous mass from the medullary canal when the bone is sawed. Oil and pus escape from the canal when it is opened. Abscesses and thrombosis of veins are found in the tissues surrounding the diseased bone; bacteria are found in the marrow and other structures, and pyaemic abscesses frequently arise secondarily. It may occur in short or flat bones as well as in long bones, and is due to mycotic infection. The microörganism or microörganisms are probably those known as pyogenic. The periosteum is often involved in a similar inflammation, but not necessarily so. The bones are in severe cases stripped of periosteum and become necrotic from one epiphysis to the other. Separation of the epiphysis from the shaft is common, and is due to destruction of the intervening cartilage. SYMPTOMS.–The symptoms of ostitis are with difficulty differentiated from those of periostitis and myelitis, with which the former affection is so frequently accompanied. In the early stages the symptoms are often very indefinite. Dull aching or gnawing pain, especially severe at night and Varying with the conditions of the weather, is a common symptom in chronic ostitis, and the inflammatory signs spoken of in the discussion of periostitis will probably be observable in the later stages. Enlargement of the bone without much change in its outline was formerly thought to be characteristic of ostitis, but it is due largely to the concurrent periostitis. In ostitis, unaccompanied by much peri- ºstitis, irregular flattened swellings on the surface of the skeleton change the contour greatly. Some of the increase in size in these inflammations is apparent, being due to the overlying soft tissues. A feeling of weak- ness and heaviness in the limb is frequently described by the patient. * 306 D IS E A S E S A. N. D. IN J U R I ES OF B O N E S. Lücke has employed percussion with a small rubber-tipped hammer to determine the existence and exact seat of Osseous inflammations. Corresponding parts are struck and the existence of increased sensibility determined; and then its superficial or deep location estimated by the forcé required to develop tenderness. There is greater dulness on percus- sion when the bone is compact, or infiltrated with inflammatory exudations, than elsewhere. - Left knee higher than right, Superficial ulcer.

Acute inflammation of the bone and marrow, called acute Osteomye- litis, or acute infective osteomyelitis, may be associated with a similar periostitis, and when it occurs without a recognized injury is often mis: taken for rheumatism. The sudden development of fever with chills and delirium, accompanied by severe pain in the limb of a person So Young that the epiphyses have not yet become united to the shafts, should be carefully examined and watched. If redness and oedema occur, and espe: cially if crepitation from inflammatory destruction of the epiphyseal cartilage is developed, or if the joint is involved, the diagnosis of infective osteomyelitis is confirmed. Abscess under the periosteum and muscles, necrosis, septicæmia, and pygemia are later symptoms. Thickening of the bone and early ossification of the epiphyseal cartilage will probably occur in cases of only moderate severity. This disease is most frequently found in the long bones of the lower limb; and occurs before ossification of the epiphyseal cartilages, which is not completed in the tibia and femur until about the twentieth year. TREATMENT.—The treatment of ostitis is almost identical with that of periostitis. If medical remedies fail a deep periosteal incision should be made, which may be at once, or subsequently, followed by longitudinal section of the bone with a Hey's saw or the circular saw of the surgical N E C R O S IS OR M O R TIFICATION OF B O N E . 307 engine. This incision should be deep enough to go into the cancellated structure or medullary canal of the bone. Cutting out one or more disks with the trephine answers a similar purpose in relieving tension and pain, and is often better, even if there is no abscess cavity in the bone to be curetted. Acute infective periostitis and Osteomyelitis must be met by early and free incision of soft parts and periosteum, down to the bone, and thor- ough disinfection of the diseased tissue with antiseptic solutions. Corro- sive sublimate solution (1:1000 or 1: 2000) is probably the best ; but it must be watched if repeated daily, so that it may not produce toxic effects. Beta-naphthol solution may be used in its stead. Free drainage and anti- septic washing of the cavity daily are essential. Separated epiphyses should be kept in position by splints; dead portions of bone removed and the patient kept alive by tonics, good food, and stimulants until the force of the mycotic poison has been exhausted. When the infective inflam- mation does not involve the periosteum to any extent, but is limited to the bone and marrow, the general treatment is the same as in associated periostitis and osteomyelitis. The local treatment consists in boring into the bone with a trephine and scraping out with a curette the inflamed suppurating marrow. If neces- sary, more than one trephine opening may be made, or two or more such holes may be connected by cutting away the intervening bone with a chisel. Complete removal of the diseased tissue and disinfection of the cavity are the indications. Necrotic bone should be removed when it becomes loosened from the living Osseous tissue. This is usually a secondary operation, unless trephin- ing and curetting have been done in the early stages. The latter opera- tions are indicated as soon as a probable diagnosis is made. It is better to operate too early than too late. Amputation may be required to save life in infective osteomyelitis and periostitis. NECROSIS OR MoRTIFICATION OF BONE. DEFINITION.—Necrosis is death of bone in masses or in bulk, in con- tradistinction to caries, which is death in minute particles. It is pathologi- cally identical with mortification or gangrene of soft tissue. CAUSES.—Necrosis is caused by anything that at once destroys vitality of bone, such as intense heat or cold, crushing pulpefying injuries; and by whatever prevents the continuance of the blood circulation through the Haversian canals and their ramifications, thereby interfering with the bone's nutrition. Obstruction of these blood spaces by the exudate of Ostitis, and detachment of the periosteum or inflammation of the marrow by reason of suppurative inflammation of these structures, are the most Common direct causes of necrosis. Osteo-myelitis, whether central (endos- titis) or cortical (periostitis) is probably the most frequent cause. They act by interfering with proper blood supply, which is arrested by stretch- ing, compression and thrombosis of the vessels. Syphilis and tuberculosis may, by inducing ostitis, act as remote causes. The depressed vitality of old age and of eruptive fevers, division or embolism of the nutrient artery of a long bone, and exposure to the fumes of phosphorus are occasionally Causes of mortification of bone. If a piece of bone is torn loose from its Periosteal attachments, as happens in compound fractures, necrosis is not apt to occur, unless the wound is infected with putrefactive or pyogenic 308 D IS E A S E S A. N. D. IN J U R I ES OF B O N E S. germs. This proves that it is the septic character of a given periostitis that inclines it to cause necrosis. PATHOLOGY..—The occurrence of necrosis more frequently in compact than in cancellated osseous structure is due to the greater ease with which the circulation is obstructed in the former unyielding structure. The usually dry condition of the dead bone shows the dependence of this necrosis on deprivation of blood supply. If death occurs in cancellated tissue, which is normally more vascular than the compact, the necrotic tissue, especially when the destruction is sudden, is moist instead of dry. The moist form of necrosis is seldom seen except in military practice, and then usually in the cancellated portions of bones. It is liable to occur as a sequence of severe gunshot contusion of bone or compound fractures, and is evidently the result of septic infection of some sort. The dead bone has a dirty-gray or greenish-brown color, is moist and soft and emits a very offensive odor. The periosteum is usually found in a slough- ing condition, and shows little tendency to form new bone. Death from pyaemia is a common result of moist necrosis. In the ordinary variety of necrosis the devitalized bone is dry and hard, and has a relatively large proportion of mineral constituents. When struck with a probe it often gives a sonorous note, but is not sensitive to touch, nor does it bleed. Its color is yellowish-white, unless it has become blackened by contact with putrid pus or other agents. The necrotic action may pertain to the surface of a bone (superficial necrosis) to a por- tion some distance below the, perhaps healthy, bone surface (central necrosis), or to the entire thickness of the bone (total necrosis). FIG. 128. Central necrosis, showing new bome and cloacae. After osseous tissue has died, it is separated from the living bone by the process of rarefying ostitis or ulceration, exactly as gangrenous parts are separated from soft tissues. The adjacent bone becomes inflamed, softened, and ulcerated, and soon a line of demarcation appears. It re- quires a long time, varying from weeks to months, according to the extent and situation of the necrosis, to effect complete detachment. Very often pus infection occurs and suppuration takes place between the dead and living bone. During the accomplishment of this process the overlying periosteum becomes abnormally active in producing bony tissue, probably because of the induction of a chronic periostitis, and deposits a layer of new bone. This new bone may form a covering over the necrosed part, or, if the latter is central, increase the thickness of the surrounding living bone. In this manner the devitalized bone is usually, by a process of invagination, enclosed in a bony sheath or involucrum of irregular shape, which, however, conforms somewhat to the outline of the original bone. If the periosteum has previously been entirely destroyed, no invagination occurs. The dead portion of bone enclosed in the sheath is called the sequestrum, while the leaf-like portions detached in cases of superficial N E C F O S IS OR M O R TIFICATION OF B O N E . 309 necrosis are termed exfoliations. In cases of total necrosis the endosteum may also furnish new bone, so that the dead structure lies between two layers of newly-formed Osseous tissue. There is usually no invagination in necrosis of the skull or of the cancellated bones. Through the living bone, whether original or newly formed, which covers the sequestrum, narrow channels or fistules, called cloacae, are es- tablished by the discharge, formed at the line of demarcation, making its way to the surface. These cloacae communicate with sinuses extending through the overlying soft parts of the cutaneous surface, which sinuses are the remains of collapsed abscesses that were developed soon after pus formed in the bony structures. The surfaces of a sequestrum or exfoliation are usually rough and jagged, because the living bone has been eaten away from it by rarefying or suppurative ostitis. The external surface of an exfoliation is some- times quite smooth, since it may have been originally the normal surface of the bone. The sequestrum may be dense or spongy, according as it has been sclerosed or rarefied before death. After some amputations of the thigh in which the nutrient artery has been divided, necrosis of the area of bone nourished by this artery occurs, while the regions nourished by other vessels coming from the periosteum and endosteum remain healthy. As a result, a tubular or cylindrical sequestrum is formed and may, when finally detached, be pulled out from the sawn end of the bone. 93 unches Cylindrical sequestrum from femur. SYMPTOMS.—The early symptoms of necrosis are those of ostitis fol- lowed by inflammation, and often of suppuration of the overlying soft parts. Through the openings or sinuses left after the evacuation of the pus, a hard and more or less rough surface can usually be felt with the probe if the necrosis is superficial. This is the dying or dead bone un- Covered by periosteum. Bare bone, however, is not necessarily dead bone, for after periostitis and ostitis of a simple kind we may have an ulcerated surface of bone that is slow in healing. In cases of central necrosis the probe must be passed through the sinuses in the soft parts and the cloacae in the involucrum or sheath before the rough sequestrum can be felt. Until sinuses and cloacae have been formed it is practically impossible to diagnosticate necrosis from ostitis or tubercular caries and abscess. The fever and other constitutional symptoms may be marked during this early stage, but are apt to decrease in severity with the evacuation of any puru- lent accumulation which may become thereafter the seat of putrefaction from germ infection. From time to time, however, exacerbations of the Symptoms may occur, and new abscesses may form. The symptoms during this, the dying stage, are more chronic in progress when necrosis happens in Spongy bone. When the osseus tissue is killed at once the symptoms of this stage are absent. The stage of separation, as the period occupied in detaching the dead structure may be termed, has characteristic features. Chronic discharge from the cloacae and overlying sinuses, increased 310 D IS E A S E S A N D IN J U R IES OF B O N E S. thickness of the bone and gradual impairment of health, if the disease is extensive, are the most prominent. Symptoms of waxy degeneration of the liver or kidneys may arise. The time occupied in separation varies from a few weeks to many months; being shorter in the upper limb than in the lower and when the necrosis is superficial or circumscribed than under opposite conditions. That separation has been accomplished is known by the motion that can be communicated to the sequestrum by a probe passed into the openings. This is sometimes better determined by introducing two probes, one near each end of the sequestrum. Sometimes the sequestrum is not movable, even when completely detached, because it is imbedded in the granulations on the inner surface of the sheath." If this condition is suspected a strong probe should be used to force the sequestrum down upon the granulations until they are flattened and the cavity enlarged. Motion can probably then be detected. PROGNOSIS.—The prognosis in necrosis as to final restoration of the usefulness of the part is generally good, except in acute septic cases. The disease seldom extends beyond the epiphyseal cartilages, and, after re- moval of the dead bone, the sinuses heal, leaving, however, some deformity in contour. Death at times does occur in the early stages, as, for example, in cases following acute Septic osteomyelitis or periostitis; so also exhaus- tion from prolonged suppuration or pyaemia may lead to a fatal issue. Again, death may result from secondary implication of other structures. This is illustrated by brain disease following necrosis of the skull, arthritis subsequent to disease of the patella and laceration of the femoral artery by necrotic spicules from the femur. Pyaemia from moist necrosis is not uncommon ; but fortunately this form of bone disease is quite rare. TREATMENT.-The indications in the first stage are to moderate accom- panying inflammation by treating thoroughly the causative Osteomyelitis or periostitis, to open abscesses early, and to keep up the general health. A blister will sometimes hasten suppuration and thus be beneficial. Early incision of the periosteum is often valuable, since it relieves pain and tends to prevent extensive destruction of this membrane and the bone by sup- puration. So trephining the inflamed bone and scraping away the diseased medullary tissue are valuable operative procedures. Disinfectant solu- tions should be freely employed to allay fetor; and all cases should be treated with rigid antiseptic measures. As soon as the dead bone is loose, it should be removed by operation. An exfoliation can be lifted away with a chisel after simple incision of the musculo-cutaneous coverings. When the bone has been devitalized by caustics or burning, and the dead area is easily determined, there is no objection to cutting it away with the chisel even before detachment has taken place, for it hastens the cure. A sequestrum should seldom be removed until it is entirely loose. To effect its removal an opening should be cut in the encasement by means of small sharp chisels and a hammer, or with a saw or trephine, until the sequestrum can be seized with strong forceps and pulled out. Sometimes the cloacae simply need enlargement; at other times the bridge of new bone between two of them must be cut away. The surgical engine, by which circular saws and burrs can be rotated with great rapidity, may be very useful in these procedures. After application of the Esmarch apparatus an incision should be made in the line of the principal sinuses and cloacae, and the exposure of the bone will then enable the surgeon to determine upon the proper method of reaching the necrotic piece. The encasement should be freely cut, but in such a manner as not to weaken the bone more than necessary, N E C R O S IS O R. M. O. R. T.I. FIC ATION OF B O N E. 311 nor to fracture it transversely. Occasionally it will be found easier to get the sequestrum out after it has been divided into portions by the bone- cutting forceps. The cavity left is generally lined with granulation tissue, but in tubercular subjects its walls may be carious. Such carious bone should be scraped away with a gouge. In getting access to the seques- trum, the surgeon should not feel compelled to follow the sinuses or cloacae; any safe path of attack which gives best opportunity for thorough removal is justifiable. After the operation is completed the wound should be stuffed with dry antiseptic gauze, the limb. enveloped in a similar dressing, and a roller bandage firmly applied to the parts before the elastic band of the Esmarch apparatus is removed. Subsequently to this operation, called sequestrotomy, the encasement contracts, new bone is formed in the cavity of the sheath, as well as under the preserved periosteum, and the sinuses and cloacae become closed. The medullary cavity, if destroyed, is, as a rule, not reëstablished. There are some circumstances in which it is probably better to operate before detachment of the sequestrum is complete, notwithstanding the possibility of thus tearing away portions of the living bone. This is the case in acute necrosis from sub- periosteal abscess and septic osteo- FIG. 130. myelitis and in moist necrosis; f/sºu.A SKIN -Yº, for more extensive destruction of the periosteum and septicæmic complications may perhaps be obviated by early excision of the dead structures by means of saws. The periosteum should be peeled off and preserved in these opera- tions so that the flail-like limb, often left, may have an oppor- tunity of becoming solidified and useful. An objection of some force against waiting too long for separation in ordinary chronic dry gangrene is the very great thickness of the encasement that occurs. Three to six months is probably long enough to wait in the majority of such cases. Small pieces of healthy periosteum or of bone, taken from man or the lower animals and kept aseptic, have been inserted in the gaps left by extensive operations of this kind. Such bone chips act as centres of bone formation, thus hastening and perfecting the regeneration of the removed shaft. It is absolutely essential that the cavity from which the seques- trum has been taken be made perfectly aseptic by the removal of every particle of diseased bone, diseased granulations, and discharge. Herein lie the difficulty and frequent failure of the method. These osteo-plastic operations deserve further trial in cases in which the bone has been exten- sively destroyed. The methods of performing sequestrotomy, adopted before the advent ºf modern antiseptic surgery, gave good results; though the healing of the remaining wound was very prolonged. It was always the seat of pro- tracted suppuration. Septic complications were, however, uncommon; because the dense inflammatory infiltration of the surrounding osseous and other tissues rendered septic absorption difficult, and the open wound With rigid bony walls made drainage thorough and perfect.

Antiseptic surgery has much shortened the process of healing by making possible the implantation of cellulo-cutaneous flaps and the organization and ossification of aseptic blood-clots. |FIG. 131. Neuber's method. Top of involucrum removed, skin flaps turned into the bottom of the bone cavity. (GERSTER.) Implantation of cellulo-cutaneous flaps may be done in order to cover the fresh surface of living bone, left after cutting away all diseased bony structure, and thereby obtain primary union between the bone and the turned- in cutaneous flaps. This leaves little or no bony surface to heal by granulation and hastens cicatrization; though, of course, a defect is left in the contour of the part. This defect would also occur, even if the process of implantation was not adopted. The turned-in flaps are held in position by sterilized mails driven through the flap and into the bone, and by sutures passed through the skin at the edges of the cavity and carried across the gap; or by sutures carried through the edges of the flaps and then brought out and tied upon the opposite side of the limb. These different methods are shown in the cuts from Gerster. The nail and sutures are removed at the end Implantation of cutaneous edges of three or four weeks; which, if the into the defect by transfixing catgut wound has been made and kept aseptic, suture. (GERSTER.) will probably be the date of first change of dressing. The utilization of the blood-clot to aid in rapid cicatrization is accom- plished by allowing the cavity to fill with blood, which clots and protects the wounded bone and other cut surfaces from septic irritation. The clot must, however, be kept aseptic and moist. This is done by covering the cavity with its contained clot with a piece of aseptic or antiseptic rubber-tissue, just large enough to overlap the borders of the wound. This is in turn covered with a voluminous dressing of dry sublimate gauze. The rubber tissue keeps the blood-clot moist, the dry antiseptic dressing absorbs all leakage of blood and serum. FIG. I32. CARIES, or TU BERCULAR U LG ERATION OF BONE. 313 This method of Schede is only possible when the entire mass or all the masses of necrotic bone are removed, when all the pus-infected membrane and granulation tissue lining the irregular tracks and cavities have been scraped away with absolute certainty, and when the cavities so made have been thoroughly sterilized by sublimate solutions and wiped clean with aseptic sponges. Gerster recommends sublimate lotion (1 : 500) to be first used, and to be subsequently washed away by a weaker sublimate solu- tion, so that toxic effects may not follow the retention in the wound of small quantities of the strong lotion. FIG. I.33. DRESS/NGS'. Schede's method. Diagram showing relations of organizing blood-clot. (GERSTER.) If it is impossible to remove a sequestrum, excision of a portion of the bone or of the joint may be demanded. When the destruction of bone has been very great, or the patient is already sinking from exhaustion, due to long-continued bone-disease, amputation may be the most judicious treatment. CARIES, OR TUBERCULAR ULCERATION OF BONE. PATHOLOGY..—The inflammatory disintegration or erosion, called caries, is a process similar to ulceration in soft tissues, for the destroyed structure is removed in small particles, usually in a more or less liquefied form. In this circumstance caries differs from necrosis, in which the devitalized portion of bone is separated from the surrounding living Osseous tissue in masses. Caries, therefore, corresponds with ulceration of soft tissues; necrosis with gangrene. As there is clinically a gangrenous ulceration of the soft parts, in which the two processes are combined, so there may be a necrotic caries of bone. Caries occurring without formation of pus is the so-called rarefying ostitis, or dry caries, which has been mentioned when Ostitis was discussed. The form of caries most often seen is that in which the inflamed bone softens and disintegrates and causes the so-called “cold abscess” within or upon the surface of the bone. It is due to infection With the tubercle bacillus, and results from the breaking down of cheesy tubercles and inflamed bone. Caries is the result of bone inflammation, and therefore depends upon the constitutional causes that induce ostitis. Ostitis is seldom, if ever, followed by liquefying caries unless the part is infected with the tubercle bacillus. Caries is often associated with inherited or acquired syphilis, but it is possible that syphilis may not be the actual cause of the caries, but simply a cause of lowered resistance which makes tubercular infection 314 D IS E A SES AND IN J U R I ES OF BO N E S. easy. The cancellated tissue found in the extremities of the long bones and in the vertebrae, carpus, and tarsus is especially subject to the invasion of caries in those predisposed to this disease; but it may occur in any part of the skeleton. In tubercular persons it often follows injury. An ulcer of the soft parts may involve the periosteum and bone, and lead to caries. Caries causes bone to become softened, porous and friable, and of a gray or brownish color before it breaks down into granular semi-liquid material. Sometimes the mineral constituents are dissolved out in the early stages of caries leaving the animal matter almost intact, so that the condition resembles that of a bone after maceration in hydrochloric acid. The organic constituents are destroyed subsequently. The removal of the disintegrated area by absorption and liquefaction leaves irregular hollows and cavities, called bone ulcers, which are occupied by the puri- form products of the destructive process. The bone around the carious focus is apt to become indurated, because Nature endeavors to construct a barrier to the advance of the diseased action. If, however, the repara- tive power of the patient is poor, and he, from some inherent constitu- tional tendency is especially liable to bone disease, no such induration or Sclerosis occurs, and the carious destruction spreads, involves the joints, and attacks adjacent bones. FIG. 134. Caries of bone. The products of carious destruction consist of oil globules, degenerated cells, blood corpuscles, granular inorganic particles, and bone salts, with which are found the bacillus of tuberculosis. The products are the results of cheesy degeneration and emulsification of the Osseous tissue. Small masses of necrosed bone will sometimes be found in the liquid, where the two processes, caries and necrosis, have coexisted. Caseous masses, or tubercles, will be found in the interior of the bone tissue, but the surface of the bone is usually involved, either primarily or secondarily, and localized periostitis and inflammation of the overlying soft parts arise. As a rule, a puriform collection, or “cold abscess,” subsequently occurs in the tissues over the bone, which spontaneously opens and affords an avenue of escape for the liquefied bone material. So long as the carious disintegration continues to furnish a discharge, the sinus, left by the col- lapsed abscess, will not permanently close. Septic and pyogenic infec- tion frequently occurs secondarily, and contributes to this condition. The sinus may cicatrize superficially, because but a small amount of fluid is formed in the depths of the track, but as soon as a few drops collect the tissues inflame and the orifice reopens. Very occasionally, as in some cases of caries of the vertebral bodies, so little discharge is furnished that it is entirely absorbed, leaving no caseous or puriform deposition. These may be called cases of dry caries. Bone ulcers heal, as do ulcers in soft parts, by granulation and cicatriza- tion. The loss of tissue is partially or entirely replaced by a granulation CARIES, OR TU BERCULAR U LC E RATION OF BONE. 315 tissue which undergoes ossification. The attempts of nature to fill up the cavities left after caries with scar tissue may be quite successful, so far as utility of the parts is concerned, if the destruction has not been very great; but depressions, though with rounded margins, are usually left. . A great deal of bone is often formed in the endeavor to fill up deep cavities, which remains in the form of protuberances and bridge-like masses. The granulation tissue by which cicatrization is often effected may in turn be- come infected with the tubercle bacillus, and be, therefore, useless as a reparative agent, because of its continuing indefinitely to undergo cheesy degeneration. SYMPTOMS.–The early symptoms are necessarily those of ostitis and periostitis, or of both, and are followed by those of “cold abscess” of the soft parts. When this puriform collection has been evacuated, either spontaneously or by incision, the cavity does not promptly heal, but leaves a sinus which discharges thin puriform fluid continuously or intermittently. A probe passed down this sinus will come in contact with the bared and roughened bone, if the track is not too crooked to be followed to its bottom. The carious surface of bone is, as a rule, not tender when touched with the instrument, but it may bleed. If it is im- possible to feel the diseased osseous tissue with the probe, the diagnosis may be made by persistent failure to effect permanent healing of the sinus, for which no other cause exists, and by chemical examination of the fluid showing a large amount of calcium phosphate. The discharge is often offensive in odor because of putrefactive infection, and contains gritty particles of bone. If there is much disease, several sinuous tracks with characteristic orifices surrounded by a little elevation of granulations will probably be found converging toward the same region of bone. When the overlying tissue has been ulcerated away, the diseased bone will be exposed to view, though covered in places more or less completely with fungous granulation tissue. Coxitis, angular curvature of the spine, called Pott's disease, and the various forms of joint disease, formerly called white swelling, are instances of caries or tuberculosis of bone. When caries attacks bones near the joints, or involves the articular ends of the bone, as it often does, ankylosis is likely to occur, because of inflammatory involvement of the joint structures. On the other hand, the tubercular synovitis may occur first, and lead secondarily to caries of the bone by first involving the articular cartilages. TREATMENT.—Iodide of iron, cod-liver oil, combinations containing phosphoric acid, good food, healthy surroundings, sea air, and similar therapeutic and hygienic agents are essential factors in the management ºf tuberculosis in bone. Even stimulants may be required. Antisyph- ilitic remedies are often required in full and long-continued doses, but combined with tonics. In the early stages while the disease is active, cleanliness, disinfection of the parts, and the prevention of external sources of irritation or infec- tion are the indications for local treatment. Rest of the parts, complete and constant, is imperatively called for, especially when the vicinity of * Joint is affected. This is to be obtained by preventing motion by *ºns of gypsum or silicate of sodium splints, by permanent extension, and similar mechanical appliances. This does not necessarily imply that the Patient must be kept in the house or in bed. Confinement is often dele- terious while open-air exercise is valuable. When liquefaction of the tubercle occurs free incision should be made for the escape of the fluid, and the whole of the diseased and softened 316 I) IS E A S E S A N ID IN J U R IES OF B O N E S. bone should cut away with gouges. This should be done antiseptically and the resulting cavity dusted with iodoform. When the cavity is in- accessible or very large it may be injected with solution of iodoform in ether (1:20). Of this from 1 to 3 fluidounces should be used and then Squeezed out after it has been brought in contact with the whole interior of the cavity in the bone and soft parts. The possibility of iodoform poisoning must be recollected, if large quantities are used in cavities, such as those of psoas abscess, where it is difficult to press out the excess of fluid. Cure can often be hastened by the early operative removal, even before liquefaction has occurred, of the soft, devitalized bone and fungous gran- ulation tissue, which impede repair, Natural processes can effect the removal of this material only after the lapse of many weeks or months, and the protracted discharge necessitated not only debilitates the patient, but has a tendency to cause waxy degeneration of the liver and kidneys. Sulphuric or hydrochloric acid diluted with equal parts of water has been recommended to dissolve away the softened bone. It may be injected into the sinuses or brushed upon the surfaces exposed by a flap incision. If the bone can be reached by incisions not too extensive, scraping away the spongy and devitalized Osseous tissue, and the fungous granula- tions, is more prompt and sure. To do this effectually Esmarch's appa- ratus should be applied to prevent hemorrhage obscuring the view. With a gouge, chisel, scraper, or the rotating burr of the surgical engine the surgeon removes the unhealthy structures. The operation should be dis- continued when healthy bone is reached, which is recognizable by its comparative hardness, and the hemorrhage occurring from its surface. When the healthy bone is of nearly the consistency of the diseased parts it can be recognized by the pink color due to its vascularity. The cari- ous bone when washed with water will be white, gray, or black. The possibility of general tuberculous infection from the tuberculous area leading to acute tuberculosis and death, is a factor strongly pointing to operative removal of the local tuberculous focus when it can be readily and safely done. In extensive caries, excision, arthrectomy, or amputation may become necessary, but these capital operations should not be done hastily, since caries is a disease of chronic type. The lapse of a few months devoted to a general constitutional treatment and local measures may change a hopeless looking limb or joint into one that will be much more serviceable than any artificial one. The possibility of fatal exhaustion from the long train of progressive bone disease may lead one to amputate at a rather early date. Passive motion of joints affected with tuberculosis may be cautiously begun, when cure seems to be fully instituted by the absence of heat, pain, and discharge, and even when some discharge is present, if it is small in amount. While believing that tuberculosis of bone or other tissues may be the local disease from which general infection of the patient may occur, I am still sure that cure of the local disease and subsequent freedom of the patient from other tubercular infections are not infrequently obtainable without operation. It is here that good judgment and experience are valuable. CENTRAL CARIES OR TUBERCULAR ABSCESS OF BONE. The process usually called circumscribed “suppuration " of Osseous tissue, or “bone abscess,” is probably more common than is usually Sup- TU B E R C U L A. H. A. BSC ESS OF B O N E . 317 posed. Such collections of puriform fluid are instances of caries and are probably always due to the tubercle bacillus. They may occur in any part of a bone, but are more common in the cancellated structure of its extremities. The head of the tibia is the common site. These tuber- cular collections within the structure of the bone must not be confused with abscess in the medullary canal and suppurative Osteomyelitis, which is a different pathological condition. The cavity may be lined by a soft membrane, or its walls may be roughened carious bone. Sometimes there is a narrow track or sinus leading from the cavity to the exterior of the bone, which in such a case would possibly have a carious surface; but often the pus is completely enclosed in a bony prison. The symptoms are usually very chronic in their progress and resemble those of ostitis, which is to be expected, as so-called abscess is merely a consequence of tubercular ostitis. Long-continued Osseous pain distinctly localized, es- pecially if near the extremity of a long bone and severe, should always sug- gest abscess. Circumscribed myelitis, necrosis, and cysts within the bone structure may give somewhat similar symptoms, but the treatment is similar in all these conditions and a differential diagnosis is not very important. Accompanying periostitis may add its symptoms to those of bone abscess. Treatment affords prompt relief from pain, and consists in dissecting up the soft tissues and periosteum and applying the trephine to the bone at the most tender spot, so as to open the cavity, to give vent to the puriform fluid, and to permit curetting of the interior. If the inner surface of the wall is carious, it should be cut away with the gouge or burr; if necrosis exists the sequestrum should be re- moved. If no pus-like fluid is found the trephine may be applied at an- other spot, or better, perhaps, a drill may be made to perforate the bone in Various directions from the bottom of the first trephine hole. Trephining should always be done early, as it is at once followed by cure if a puriform collection is present. If no fluid is present the operation does no great harm, and will probably ame- liorate symptoms by decreasing tension. If no collection of pus-like fluid is found in the body of the bone it is well to bore into the marrow cavity before desisting, as it is possible that a chronic medullary abscess may be the cause of the symptoms.

EPIPHYSITIS. Inflammation of the cartilage situated between the shaft of a bone and its epiphysis occurs at times in children, especially in those of low vitality. The inflammatory bone conditions already discussed are apt to be asso. ciated with epiphysitis, though it is possible that it may be primary in its origin. The symptoms are similar to those of periostitis and arthritis, except when separation of the epiphysis and the preternatural mobility and crepitus there evoked show the loss of the uniting cartilage. Close scrutiny will usually prevent confounding epiphysitis with arthritis. The symptoms, prognosis, complications, and treatment are similar to what has been detailed in the consideration of Ostitis. Early and free incision, even if no pus is suspected, is good surgery. Even those cases that recover without extensive destruction of tissue are apt to show subsequent arrest in development of the bone, because the Osteogenetic function of the cartilage has been impaired. Tonics and nourishing diet are neces- sary in all cases. HYPERTROPHY AND ATROPHY OF BONE. General increase of a bone in length and thickness, to which the name hypertrophy is often applied, is in most cases an inflammatory enlarge- ment due to chronic ostitis, periostitis, and epiphysitis. Even after the inflammatory process has subsided the bone retains its increased dimen- sions. This is not hypertrophy in the true FIG. 136. pathological sense. Hypertrophy may occur, - however, when unusual functional demands are made upon a bone. An instance is seen in the increased size and strength of the fibula occurring when the tibia has been destroyed by necrosis. The fibula, being gradually called upon to support unaccustomed weight, becomes hyper- trophied from increased functional activity. A localized increase in bulk of a bone is more properly called an Osteoma or bony tumor. Hypertrophy of bone in itself neither demands treatment nor is amenable to it. Exostoses and other forms of osteoma may be excised if disfigurement or other reasons make operative treatment desirable. Atrophy of bone is said to occur in two forms, in both of which there is decreased weight. In one variety the bone becomes º smaller in size, with simultaneous absorption º of the cancellated and compact tissue, and diminution of the calibre of the medullary \ || | ;4. } i | t º canal. This change occurs after long disuse, Senile atrophy of head and as in stumps after amputation, and in joints neck of thigh-bone. (GRoss.) where ankylosis, dislocation, or paralysis has long existed. It is observed most frequently in the long bones, and is a not uncommon senile change, which, when occurring in the neck of the femur, may produce shortening of the limb S OF TEN IN G O F BO N E. 3.19 and lameness, and thus simulate fracture at that point. As such localized atrophy, which is frequently associated with fatty degeneration, may hap- pen after injuries, the practical knowledge of this possibility is great. Some cases of so-called atrophy of bone may be imperfect development, due to unrecognized or forgotten injuries or disease of the epiphyseal car- tilages in early life. In the other form of atrophy the bulk of the bone is not altered, but the compact Osseous tissue gradually becomes rarefied and changed into cancellated structure, whereby the bone becomes very light and brittle, and is easily broken by slight injuries. The distinction between atrophy on the one hand and interstitial absorp- tion and fatty degeneration of bone on the other hand is perhaps not suffi- ciently observed. The absorption of bone or rarefying ostitis due to pressure of tumors, for example, does not appear to be an instance of atrophy in as true a pathological sense as the disappearance of the alve- olar process of the jaw after loss of the teeth. It is true that in the former case the thinning and erosion may be due to interference with circulatory and nervous supply, causing atrophic change ; but the dimin- ution of structure following disuse corresponds more nearly with the idea of atrophy. Treatment is of no avail in curing Osseous atrophy. In cases where the function can be restored, as in ankylosis of long duration, the bone may, however, regain some of its lost bulk. OSTEOMALACIA. SOFTENING OF BONE. This very rare affection, also called mollities ossium, seems to be a gen- eral disease, though the chief changes are found in the skeleton. Its nature is exceedingly obscure. Some authors have suggested a possible identity with fatty degeneration, malignant degeneration, or atrophy of bone. Others have called it rickets of adults, since it resembles rickets, but has been observed only in adults. The clinical characteristic of the disease is progressive softening of the bones, which become so soft that a knife can readily cut them. At the same time they lose weight and are either flexible or easily broken. Various portions of one bone, and as a rule many parts of the skeleton, are affected. The external compact portion becomes little more than a thin shell, while the cancellated structure has become more spongy than normal and filled with a reddish, gelatinous, fatty material. The earthy constituents of the bone have been removed by a process of decalcifica- tion, and a sort of mucoid degeneration of the animal portion of the Osseous structure has apparently occurred. The medullary tissue is at the same time very vascular. Lactic acid has been described as found in the bony tissue and in the urine. Osteomalacia is more frequently seen in women than in men and seems to be induced by pregnancy. It is a disease of adult life. The pro- longed administration of lactic acid has been mentioned as a possible Call Se. The symptoms are pain of a rheumatoid character and a tendency of the bones of the extremities or trunk to bend like softened wax. If the Compact Outer tissue of the bone is not much decalcified, however, brittle- ness instead of flexibility will be present and fractures from slight injuries Will frequently occur. The urine usually contains a remarkable amount of phosphates, evidently derived from the degenerating bone tissue. 320 D IS E A SES A N ID IN J U R IB S OF B O N E S. Phosphates have been found also, it is said, in the saliva, tears, and other fluids. Albuminuria has been observed. The patient finally becomes bedridden, because locomotion is impossible, and dies exhausted. Osteo- malacia, unlike rickets, is painful, never occurs in children, and progresses until death occurs. The softened bones of rickets usually become hard again; such is not the case in osteomalacia. There is no efficient treat- ment known. Phosphates of lime, sodium, and potassium with cod-liver oil and tomics should be administered. Bedsores should be expected, and prevented if practicable. TUMoRS IN BONE. Bones may become the seat of tumors of various kinds, such as sar- coma, Osteoma, chondroma, fibroma, angioma, myxoma, and hydatid cysts. It was formerly believed that carcinoma was a not infrequent growth in Osseous tissue. Such is not the fact. Except when it occurs secondarily to carcinoma in other structures this form of neoplasm is practically unknown in bone. Sarcoma, however, is common. True cystic tumors are seldom found except in the jaw bones, where they are at times devel- oped from the mucous membrane of the antrum and the structures about the teeth. Tumors containing fluid found in other bones, unless hydatid cysts, are, as a rule, sarcomas, chondromas, or myxomas which have under- gone cystic degeneration. Vascular tumors, that is to say, angiomas, are occasionally seen ; but the pulsating tumors formerly described as aneurisms of the arteries in bone are probably always highly vascular S8. I’COID 3'S. Tumors of bone may be developed from the lower layer of the perios- teum or from the medulla or endosteum. Periosteal growths are usually oval or pyriform in shape, of a smooth surface, and have a capsule derived from the periosteum. The adjacent bone may be normal, hardened, ab- sorbed, eroded, or fractured. The growth, if malignant, may spread to the medulla by the Haversian canals. Endosteal or central tumors are usually spherical, smooth on the surface, and when handled may give rise to a crackling sound. The enlargement of the growth causes disappear- ance of the bone, but the periosteum becoming inflamed constantly forms new layers of bone tissue. These are absorbed in turn, but new plates of Osseous tissue are continually developed. Thus the mass acquires a more or less bony capsule, and when the patient is examined a crackling sound is elicited by the motion imparted to the membrano-Osseous encase- ment. This is the explanation of the apparent dilatation of the bone and the parchment-like crackling elicited by pressure. Non-malignant growths in bone do no harm, as a rule, other than to act as impediments to motion, and to cause deformity. They may be excised with chisels and saws if such action is demanded by the disability or dis- figurement. Sarcomas spread into the surrounding parts and involve dis- tant structures by secondary involvement through the blood-current. Amputation, early and at a considerable distance above the disease, is always demanded. & INJURIES OF BONES. Bone, together with its periosteum and marrow, may receive contused, incised, lacerated, and punctured wounds. Such wounds of bone are fre- quently obtained in war from bullets, balls, sabres and arrows, and occa: sionally are seen in civil practice. Fractures are lacerated wounds of F. R A CT U R ES, 321 bone, and are common everywhere. Osseous wounds are followed by peri- ostitis, ostitis, and osteomyelitis, which may be localized or diffused. The wounds should be treated as similar wounds of soft parts and their Se- quences on the principles detailed in the section on diseases of bone. Fractures, which are wounds or solutions of continuity, usually involving the entire thickness of the bone injured, will be discussed in the following section of this treatise. Contusions of bone may become of grave import, when a viscus, such as the brain, within the bony case, is simultaneously or secondarily involved, or when atrophy of the bone, as in the neck of the femur, is so induced. The induction of Osteomyelitis by contusion is another serious complication of what may seem a trivial injury. Bending without fracture occurs at times in very young bones or in those softened by rickets or osteomalacia. The treatment is to bend them forcibly into proper shape, or to do so gradually by means of well- padded splints or the elastic tension of rubber straps. Muscular action or the elasticity of the bone may correct such deformity in children with- out much treatment. The surgeon should not hesitate to straighten such bones by making a complete fracture if there is a probability of perma- ment deformity. FRACTURES. DEFINITION.—A fracture is a sudden breaking or tearing apart of Osseous fibres; in other words, a lacerated wound of bone. A solution of continuity due to disease or to division by saws or sharp instruments is not a fracture, though in its treatment and mode of repair it may be similar. The term fracture is also applied to breaking of car- tilaginous tissue. CAUSES.–For the production of a fracture an exciting cause must always be present, but certain characteristics of the patient or of the special bone may act as predisposing causes. The atrophy of bone occur- ring in old age and in the subjects of locomotor ataxia, osteomalacia, rickets, and malignant diseases of bone, are efficiently predisposing causes, for they render the bony tissue less able to resist strain. Syphilis and tuberculosis have been called predisposing causes, but probably on insuffi- cient evidence. General paralysis of the insane seems to be associated with brittleness of bones. This is probably due to atrophic changes in the Osseous structure. Stimson states that the greater fragility of bone in the aged is to be attributed to senile atrophy, and not, as is often asserted, to a greater relative proportion of inorganic material. A bone, by reason of its exposed position, its curves, its function as a lever, or its small pro- portion of compact osseous tissue, may be more liable to suffer fracture than the adjacent pieces of the skeleton. On the other hand, a flat, movable bone, surrounded by muscles, such as the scapula, is very unlikely to be broken. The exciting causes of fracture are external violence and muscular action. External violence is said to act directly when the bone is broken at the point of impact. It is a crushing force that causes disruption of the Osseous fibres in these cases. Gunshot fractures and fractures caused by kicks and by falling timbers are thus produced. External violence is Said to act indirectly when the fracture occurs not at the point struck, but at some distant part of the skeleton. The force is transmitted thither through the intervening bones, and tears the bony fibres apart by lever- age, torsion or traction. Muscular action is not a very frequent cause of 21 • 322 D IS E A SES A N D IN J U RIES OF B O N E S. fracture except in fracture of the patella. That powerful muscular con- tractions may cause fracture of long bones is proved by instances occur- ring in athletic persons during efforts of throwing or lifting. Similar injuries have been reported as taking place during tetanic or epileptic spasm of muscles. Fracture of the patella, olecranon, of the posterior end of the calcaneum and of the coracoid process of the scapula is usually due to powerful muscular action. Breaking of the patella by contraction of the four-headed extensor of the leg may possibly be at times rendered more easy on account of lever- age action exerted upon the bone as it lies in contact with the condyles of the femur. Stimson, however, believes that it is usually a giving way, as a rope, from direct traction, exerted by the muscle. The muscles, by hold- ing the bones in fixed positions, may indirectly assist external violence in causing fractures. This will be understood by considering that a cadaver thrown from a height is less likely to sustain fracture than is a living body. Fºcure occasionally take place in the uterus; due usually to violence inflicted upon the foetus by injuries received upon the abdomen of the mother. A rachitic foetus is prone to suffer such Osseous lesions from com- paratively slight force. It is possible, however, that some supposed intra- uterine fractures are really instances of defective ossification. VARIETIES.—There are two kinds of fractures; the open and the closed. The open fracture is one in which the broken surfaces are ex- posed to atmospheric contact by reason of a communication with the FIG. 137. FIG. 138. º º º \,\! St. - l; Diagram of comminuted fracture. Impacted fracture of neck of ſemur. (MUTTER MUSEUM.) surface through a wound of the muscles, fascia, and skin. A closed fracture is one with which no such wound coéxists, and which is therefore protected from atmospheric influences. The former are often called com- pound fractures; the latter simple fractures. As these terms are not F. R A C T U R E S. 323 self-explanatory and are otherwise objectionable, they should be dis- carded. Closed fractures are sometimes denominated subcutaneous frac- tures. This use of the word, though convenient, is misleading, because it seemingly implies that the fracture is an open one whenever the skin in the vicinity of the fracture is laid open. Such is not the fact. Com- munication with the air is the requisite of an open fracture; hence the muscles and fascia, as well as the skin or mucous membrane, must be perforated or divided. The open character of a fracture may be due to the vulnerating force causing laceration of the soft parts, to its continuance inducing protrusion of the fragments, to the weight of the unsupported limb giving rise to a similar protrusion, or to secondary ulceration and suppuration. Open fractures are much more serious than closed fractures, because pyogenic bacteria gain admission to the wound and suppuration generally occurs about the ends of the fragments. Union is, therefore, less rapid, and osteomyelitis of a severe type and septicæmia are more likely to arise. The modern or antiseptic methods of surgery have rendered open fractures as little liable to these complications as were closed fractures formerly. FIG. 139. | t| º ſº | (a) Transverse fracture and (b) oblique fracture. (HAMILTON.) . Yarious terms are applied to both open and subcutaneous fractures to indicate the characteristics of the broken structure: A comminuted frac. * is one in which several inter-communicating lines of fracture split the bone into a number of Comparatively small fragments. If a bone is broken at two or more different places and the lines of fracture do not *n into each other, the injury is a double or triple fracture, not a com- minuted one. tº º In an impacted fracture one fragment is driven into the cancellated 324.

It is rather rare, and can only occur, as a rule, at the extremity of bones where there is much can- cellated tissue. The lower end of the radius and the neck of the femur are the localities in which it is likely to be seen. In a transverse fracture the plane of fracture makes a right angle, or at least an angle of not less than 70°, with the long axis of the bone. Transverse fractures are rare, except in the patella and at the lower end of the radius, and when observed are usually caused by either direct violence or muscular contraction. They are probably more common in children and the very aged than at other periods of life. FIG. I.40.

Longitudinal fractures are those in which the line of fracture is not further from the long axis of the bone than 15° or 20°. They are very rare, except as accompanying such perforating fractures as are caused by gunshot injuries. Oblique fractures are those in which the line of separation is neither transverse nor longitudinal. The majority of fractures are oblique. A complete fracture of a long bone crosses the long axis of the shaft and divides the bone into two or more pieces. A fracture of a flat bone to be complete must involve its entire thickness. Under the head of in: complete or partial fractures of long bones are included the so-called “green-stick’ fractures, in which some fibres are torn and others bent, fissures, separation of mere splinters, detachment of bony prominences, and perforating fractures, such as are made by bullets. Indentations of flat bones by forces not sufficient to cause fracture through the entire thickness, are instances of incomplete fracture, Incomplete fractures may become very serious injuries; for example, F. R. A. CT U R E S. 325 fissures communicating with the marrow, if open to the external air and infected with putrefactive or pyogenic germs, may be followed by dangerous osteomyelitis. The injury sometimes called “sprain fracture,” in which a small fragment of bone is torn away at the point where a ligament is attached, is an incomplete fracture. , Rupture of the main artery, laceration of the chief nerve, extension of the line of fracture into a joint, dislocation, and other lesions may occur simultaneously with a fracture and complicate the treatment. A diastasis, or forcible separation of an epiphysis from the shaft of a bone, presents the symptoms of a fracture, and requires like treatment. Ossification of all the epiphyseal cartilages has usually occurred before the twenty-fifth year; hence epiphyseal fracture or separation can rarely happen at a later period of life than this. The line of separation is of necessity usually transverse; and commonly some scales of bone are torn from the shaft with the layer of cartilage. The innominate bone may be separated by injury into its three primary segments by a similar separa- tion through the cartilages. Arrested growth is not unusual after epiphy- seal detachments. |FIG. 142. FIG. 143. W § W § §§§ R\\ \ Fissure of humerus. (GURLT.) Diastasis, or epiphyseal separation of the head of humerus. (MooR.E.) tº PATHOLOGY:-When a bone is broken hemorrhage occurs from the arteries and veins in the Haversian canals and medullary cavity, and the Periosteum is more or less extensively lacerated. The muscles and fascia. about the seat of fracture are usually implicated in the violence, even in closed fractures with little displacement; hence extravasation of blood in and from the surrounding soft parts is common. The blood from the torn sºft parts usually shows as a blue discoloration of the skin a few hours after the inj ury. That effused from the osseous structure itself does not *ach the surface for two or three days, because it can only leak through the 326 D IS E A SES A N D IN J U R IES OF B O N E S. deep fascial coverings by means of small openings existing where nerves and bloodvessels approach the exterior. By gravitating or travelling under fascial or muscular layers it may appear quite far from the locality of fracture. The periosteal laceration may correspond with the line of fracture, but this is uncommon, because the majority of fractures are oblique, and in them the periosteum is apt to be stripped up from the bone in the vicinity of the fracture before it gives way under the tension of the dis- rupting force. This renders the line of tear irregular. In comminuted fractures some of the fragments may be held in position by untorn peri- osteum, while others are entirely denuded of this membrane. The latter are not apt to become necrotic unless the wound is infected with micro- organisms. Very occasionally it happens that a bone is broken and the periosteum left intact or nearly so. Little displacement then occurs and rapid cure without deformity is to be expected. Around the locality of fracture inflammatory processes at once occur, varying in intensity with the severity of the damage done to the bone and the soft parts. The interference with return circulation caused by the pressure of the inflammatory products may give rise to oedema of the distal portion of the limb, even in cases of fractures of very moderate gravity. The fever and other general symptoms depend on the type and degree of the inflammatory action. Albumin, tube casts, and fat have been observed in the urine of patients suffering with fractures, apparently as a sequence of the Osseous injury." The fragments of bone, except in cases of mere fissure, seldom retain their normal position. Continuance of the injuring force for a moment after the disruption of the bone has occurred, attempts to use the injured member, as in walking, dropping of the unsupported limb below the injury because of its intrinsic weight, and tonic or spasmodic muscular contraction are all displacing causes. Fractures in children show less displacement than those in adults, because greater elasticity of the bone makes the line of fracture more irregular and therefore the fragments are more apt to remain interlocked. Moreover, the periosteum is less com- pletely torn and the muscles are less powerful. Angular, rotary, transverse, or longitudinal deviation may occur at the seat of fracture. Usually, however, the displacement is a combination of these malpositions. Occasionally, as in some comminuted fractures, the displacement is too complex in its nature to be classified under these heads. As a rule, it is the distal fragment that occupies the abnormal position. Transverse fracture of the patella, fracture of the olecranon, and similar injuries afford exceptions to this rule. Angular displacement or tilting, in which the axes of the fragments form an obtuse angle, is typically represented in green-stick fractures and bending of bones, in which, indeed, it is the only form of malposition possible. In rotary dis- placement one fragment is twisted on its long axis. A good example is fracture of the shaft of the femur in its upper third. Here the weight of the limb usually rotates the lower part of the bone outward. When one fragment is displaced laterally or antero-posteriorly, transverse devia- tion exists. This form of displacement seldom happens except in com- bination with one of the other varieties. It may occur alone, however, in transverse and serrated fractures. If the ends of the fragments slip 1 Riedel, quoted by Stimson, Treatise on Fractures, 111. F R A CTU. R. E. S. 327 past each other the muscular tonicity causes overlapping, unless an un- broken parallel bone, as in the leg or forearm, prevents its occurrence. FIG. 144. FIG. 145. FIG. I.46. FIG. 147.

Fig. 147.—Diagram of (a) longitudinal displacement; (b) impaction. Longitudinal displacement is a change made in the long axis of the bone. It consists in overlapping of the fragments, in penetration of a broad fragment by a narrow one (impaction), or in actual crushing of the Osseous structure into small pieces. In rare instances, as in fracture of the patella and olecranon, the longitudinal deviation consists in separation of the pieces of bone. This is dependent upon a powerful muscular attachment to one of the fragments. Muscular action in nearly every other fracture causes shortening. It is not always possible to predict the character and extent of displacement that will occur in a fracture at a given locality, for it depends on the direction and nature of the line of fracture as well as on the muscular attachments and other above-men- tioned causes of deformity. All the forms of displacement occur in a marked degree in oblique fractures, while little deviation is seen, as a rule, in transverse ones. SYMPTOMS.–A case of suspected fracture should be examined as soon as practicable after the receipt of the injury, unless the intensity of ner- Vous collapse or some similar circumstance makes such examination more hurtful than a few hours' delay in determining the exact character of the injury. When a case is not seen until some days after the accident and Very violent inflammation has already supervened, it may be wise to wait a day or two and endeavor to lessen the inflammatory symptoms before undertaking the manipulations necessary to establish an accurate diag- nosis. In obscure cases anaesthesia should be induced that a thorough examination may not be prevented by reason of pain. In order to give the patient time to recover equanimity after the surgeon's entrance, as Well as to learn the facts of the case, questions concerning the accident should be asked before the examination is begun. If this is not done the nºrvous excitement due to pain from the examination or the insensibility of anºthesia will make the obtaining of definite answers impossible. The Possibility of deformity from previous injuries and the history of the case should be fully considered. The surgeon should then grasp the Parts firmly and examine carefully and thoroughly for deformity, abnor- mal, mobility, crepitus, and any other objective symptoms necessary to establish a diagnosis. Needless repetition of movement is to be depre- *ted as much as inefficient firmness of grasp during the manipulation is 328 ID IS E A SES A N D IN J U R IES OF B O N E S. to be avoided. A wound near the seat of fracture should be cautiously explored with the finger and probe to see whether the fracture is an open or closed one. If oil globules escape from the wound within twelve hours the wound probably connects with the fracture. It is the injured marrow that furnishes this fat. A good deal of venous oozing is also suggestive of the fracture being an open one, because the veins of soft tissue cease bleeding sooner than those of bone. The latter cannot collapse so readily. The symptoms, which, when occurring together, make the evidence of fracture conclusive, are: deformity, abnormal mobility, and crepitus or grating. One is often sufficient to establish the diagnosis, but their coexistence is pathognomonic. If one of these symptoms gives unmistak- able evidence of fracture, it is often well to desist from endeavors to develop the others, since such action but adds to the pain, and may increase the displacement of the fragments. In many fractures one or two of these symptoms, as will be shown subsequently, may be absent. Deformity is principally due to the displacement of the fragments. Extravasation of blood may aid in the primary deformity, and inflamma- tory swelling in that which occurs later. The forms of displacement, which have been already discussed on a previous page, may give rise to marked or very slight deformity. Slight deformities are often, however, much more difficult to correct than great ones. When the periosteum is slightly torn there is no deformity, because this fibrous membrane retains the fragments in apposition. Mere fissures give rise to no deformity. The recurrence of deformity, when external restraining forces are relaxed, is a characteristic of most fractures, serving to differentiate this class of injury from dislocation of joints. In estimating the degree or existence of deformity, previous fractures and injuries, periosteal nodes, exostoses, and shortening from old joint inflammations, or contracted tendons, must be eliminated. Sprains and dislocations often give distortions similar to fractures near corresponding joints, and must be discriminated by other symptoms. The two sides of the body should always be compared with the bones in exactly the same position. Angular and rotary displace- ment are generally easily recognized ; but shortening.due to overlapping is often difficult to verify, because accurate measurement is almost im- possible. The bony prominences taken as standards of comparison are rounded, therefore the tape-measure can seldom be stretched between exactly corresponding points. Another element of doubt is the well- known normal inequality in length of bones of the two halves of the body. Shortening in very oblique fractures, as of the thigh, may amount to sev- eral inches. A clot of blood, a limited condensation by crushing, or a localized swelling of the soft tissues, sometimes simulates deformity from displaced bone. This is a frequent source of error in head injuries. A long needle thrust through the skin and muscles will, by impinging on the hard bony structure, clear up this uncertainty in some cases. In fractures involving joints the peculiar deformity due to the synovial sac being filled with blood or inflammatory products may aid in proving the existence of a fracture. Preternatural mobility after injury is absolute proof of a fracture, except in those rare instances where dislocation with very great tearing of the ligaments allows unusual motion at a joint. Increased mobility is sought for by endeavoring to move one part of the bone independently of the other, and so to produce angular, rotary, or transverse deformity at the seat of injury, or shortening or elongation of the bone or entire limb. F R A C T U R ES, 329 The best method of developing these features is to hold one extremity of the bone immovable, while an attempt is made with the other hand to move the other extremity. If preternatural local motion can be obtained, and it is usually shown by the production of the deformities mentioned, the existence of fracture is undoubted. Absence of mobility must not be asserted until endeavors have been successively made to lengthen, shorten, bend, and rotate the bone at the seat of supposed fracture, because some- times the line of fracture is such that only one direction of force will develop the abnormal mobility. When the injury is near a joint where motion is a normal condition, when the bone is so short or so deeply located that its two ends cannot be firmly grasped, and when, as in the case of the ribs, sternum, and fibula, considerable normal elasticity exists, which, upon manipulation, can simulate mobility, it is difficult to be certain that preternatural motion is present. Swelling also may sometimes prevent a just apprecia- tion of the existence of mobility. Fractures, moreover, may exist with little or no increased mobility of parts. Such is the case in impacted, in partial, and in interlocked toothed fractures. When one of two parallel bones is broken, the mobility is often slight. When the shaft of a bone is broken near the middle, the unnatural seat of motion may be sufficiently demonstrated by merely placing a hand under the limb and endeavoring to lift it upon this single point of support. Motion and consequent angular distortion are at once evident. In searching for motion by rotation the fragment moved should be twisted but slightly, since the muscles may connect the fragments sufficiently closely to cause the rotation to be trans- mitted to the fixed fragment when any considerable degree of rotary movement is attempted. When a bone is intimately associated with and held quite fixed by other bones, alternating pressure with the thumbs or fingers applied on each side of the point of injury may develop motion. This method is especially applicable to the fibula and the ribs. In transverse fractures motion will be developed best by force applied laterally, and in oblique fractures by forces tending to elongate or shorten the bone in the direc- tion of its long axis. Crepitus is the grating sensation felt by the surgeon when he rubs the rough surfaces of the broken bone together. There is often some noise produced by this manoeuvre, but the diagnosis rests more on the vibra- tions conducted along the bone to the hands of the surgeon than on any noise appreciated by his ears. Mobility and grating are usually, though not always, coexisting symptoms. Grating cannot be felt without moving the fragments, but motion may sometimes be produced without making any grating sensation or crepitus perceptible. The development of crepi- tus requires, that the surfaces should be rough, and that they should be sufficiently in contact to render friction of one surface upon the other Possible. If the ends are separated, as in fracture of the patella; if they greatly overlap so that the smooth surfaces of the sides of the bone are in °ontact; if portions of muscle, periosteum, or fascia lie between the pieces; or, if the broken surfaces have by lapse of time become covered with §ranulation tissue, the surgeon will fail to observe distinct crepitus until he alters these conditions. No grating is possible as a symptom of im- Pacted or green-stick fracture unless the parts are previously rendered movable. Sometimes a certain manipulation will give rise to distinct °repitus, but afterward will utterly fail to produce a similar result. This 330 iTY DIS E A S E S A. N. L) IN J U R I ES OF B O N E S. is because by reason of muscular or external forces a different relation of the fractured surfaces has been assumed in the interval. To elicit grating the surgeon manipulates the parts in such a manner as to produce motion. In fact, preternatural mobility and crepitus are demonstrable at the same time and in a similar manner. When possible, it is best, perhaps, to move the two fragments in oppo- site directions, as this gives a greater degree of friction. When there is much overlapping extension must be made before grating can be felt. Placing the palm of one of the hands over the seat of injury is sometimes a good method of feeling grating in bones that are not easily grasped with the fingers. Motion is then obtained by the other hand alone. This often avails in fracture of the neck of the femur or great trochanter, or in rib fractures. In the last the proper motion may at times only be obtained by deep inspiration or coughing. If the limb is heavy, an assistant may steady or move one portion of the bone while the surgeon has hold of the other. In most cases the surgeon is able to control both parts with his own hands. When the presence and character of crepitus have once demonstrated the existence of fracture, no further manipulations should be attempted. The character of grating varies with the character of the fracture. It may be a single slip or snap, or it may resemble the sensation perceived when two pieces of roughened dry wood are rubbed together with the hands. In greatly comminuted fractures the sensation imparted is that of motion among a number of loose pieces of hard material. If any sound is heard at the same time it will similarly be a sharp click, a dull, muffled scraping, or an irregular crackling. The character of crepitus, however, will not always give a correct idea of the nature of the fracture. A sensation of loose grating may be felt when the bones are held closely together. The best manner of conveniently illustrating the peculiar sensation called crepitus is to take an animal's bone, obtained from the markets or else- where, and after wrapping it tightly in a towel to break it. Motion of the fragments in various directions will give almost typical grating: Fracture crepitus may be confounded with, and, therefore, must be dis- tinguished from the friction-grating of diseased joint surfaces and that of a dislocated bone rubbing on the periosteal surface of another bone. It may also be simulated by the fine crackling of inflamed tendons and bursae, that felt and heard in subcutaneous emphysema, due to puncture of the air-passages or decomposition of cellular tissue, pleuritic or pulmo- mary sounds, and the crackling of coagulated blood in the tissues. Joint grating is said to be finer and moister than fracture grating, but sometimes it is impossible to assert with positiveness which kind of crepitus is present. Those conditions giving impressions similar to fracture crepitus can usually be eliminated by collateral evidence if the surgeon merely recollects the possibility of their existence. A piece of necrotic bone may give rise to sharp grating sensations and sounds, if in a position where another piece of bone can rub against it. A curious fallacy is this: that occasionally the crepitus perceived appears to be developed in a certain bone when it is really due to fracture of a contiguous part of the skeleton. Direct auscultation over the seat of suspected fracture, either with or without a stethoscope, is probably of little value, because the sensation of rubbing, rather than the sound, is the important diagnostic feature. Perhaps auscultation may be applicable and serviceable in fractures of the ribs and sternum. The grating produced by motion of the fragments is frequently per: ceptible to the patient. Occasionally a giving-way sensation, accompanied F. R A C T U R E S. 331 by a sharp crack, is noticed by the patient at the time of the accident. A similar symptom is liable to occur, however, when a tendon is suddenly torn, or when a dislocation with great ligamentous laceration takes place. Hence, this snap, even when noticed, has little diagnostic value. It is more often observed by the patient in fractures from muscular contraction than from violence. The characteristic symptoms of fracture, then, are deformity, preter- natural mobility, and crepitus. Pain, ecchymosis, loss of function, and a variety of other symptoms may be present, but they also exist in such diverse lesions that they have, as a rule, no diagnostic value. A persistent tenderness after injury limited to a small area of bone is, however, very suggestive of fracture without displacement. The opinion of the laity, that pain in fractures increases when the fragments of bone are becoming united, is erroneous. Painful muscular spasms, due chiefly to irritation of the muscles by the sharp points of the broken bone, are frequently experienced in the early stages of fractures. Swelling deserves little recognition as a symptom of fracture, but is a factor of very great importance in the determination of the best methods of treatment. When the inflammatory swelling is rapid, numerous vesi- cles may occur on the surface. These may be filled with bloody serum. It is well not to rupture them, as the blood is often absorbed quite rapidly. Intractable ulceration at times follows if the epidermis is rubbed off before new epidermis is formed beneath that which is pushed up by the fluid. Ecchymosis about the seat of lesion is often due to mere contusion of the soft parts. If it first appears after the lapse of several days, and especially if the black-and-blue discoloration is found at some distance from the seat of injury, a fracture is probably present. This tardy ap- pearance and distant location are due to the difficulty which the blood extravasated from the broken bone, periosteum, and marrow has in reach- ing the surface through the fascial layers. This slowly occurring ecchy- mosis, particularly when the swelling of the parts results in the formation of blebs on the surface, may be mistaken by the inexperienced for incipient gangrene. Absorption of this extravasation from the deep vessels is always effected in a tardy manner. Indeed, the fracture may be united before all the discoloration has disappeared. Blood extravasated from large vessels may, it is said, cause synovitis by coming in contact with the outside of the synovial membrane. It is not essential that the synovial sac be perforated or ruptured. Rupture of a large artery as a complication of fracture is of grave import, because it gives rise to great extravasation in the tissues. Loss of power of the part often occurs after fracture, sometimes from fear of pain, sometimes from loss of continuity in the bony lever. This Symptom is absent in many cases of impacted, serrated, or partial frac- ture, and also in those in which the periosteum is slightly torn. Patients bºve walked considerable distances with a fracture of the femur or tibia. Motions which do not give pain at the seat of fracture, and which do not require rigidity of the particular bone that is broken, can be perfectly performed in nearly every case. Movement of the fingers, for example, is often unimpaired in fracture of the radius. When there are two Parallel bones, one may serve as a support to that which is fractured, and thus prevent impairment of its ordinary functions. Intermittent muscular spasms are often an annoying symptom of frac- "re. They are due to pricking of the muscles by the fragments, and to 332 D IS E A SES AN ID IN J U R IES OF B O N E S. general nervous excitability. Numbness and other nerve symptoms may be present from coincident injury to nerve trunks. The constitutional symptoms of fracture, after the period of shock, are those of inflammation and its consequences. In an uncomplicated closed fracture there are scarcely any constitutional symptoms. A slight febrile rise is often noticeable, however, during the first three days. In open fractures suppuration is usual, unless care is taken to make the wound aseptic immediately after its receipt, and to keep it so during cicatrization. Open fractures, managed as described, are usually free from suppuration, and cause as little trouble as closed fractures of similar location and extent. Great debility, erysipelas, tetanus, fat embolism, septicæmia, and pyaemia may all be seen as sequences of fractures if they are not treated so as to be free from germ infection. In old age fractures may prove fatal from the consequent debility that is induced. DIAGNOSIS.—The symptoms described will usually render the diagnosis of fracture easy; but when deformity, preternatural mobility, and grating are not all found, or, if found, are not well marked, the true nature of the injury may be obscure. Especially is uncertainty apt to arise when the lesion is near a joint, for here there is a great deal of normal mobility, and joint-grating may, from some cause, be present. Careful examination under ether, with the corresponding healthy limb uncovered so that com- parison can be made, will usually disclose the true nature of the lesion. Severe bruises can be discriminated from fractures in a similar manner. Dislocations, because of the resulting deformity, may resemble frac- tures near joints, but in dislocations, unless there is unusual laceration of ligaments, the normal motions of the articulation are impaired ; and the surgeon generally finds by manipulation that a sudden and abnormal check to free movement occurs in certain positions of the bones. This is not the case in fracture, for there the motion is almost unlimited. Again, in dislocations there is some resistance when an attempt is made to over- come the deformity by putting the parts in position, but when this has been accomplished there is little tendency to recurrence of distortion. In fractures, on the other hand, the deformity is remedied with ease, but the mere weight of the limb or a slight force will reproduce it. Voluntary motion is, as a rule, not so impaired in dislocations as in fracture, for the long lever is intact, and there is simply a change in the bearing-points of the articulation. Fractures have an appearance or “physiognomy” of helplessness; dislocations a “physiognomy” of rigidity. The normal relation of the bony prominences about a joint should be familiar to the surgeon, so that any deviation by dislocation or fracture may be detected. The various “test-lines” used for determining these relations will be spoken of in discussing fractures near special joints. The diagnosis between a separated epiphysis and a fracture in the same region is often difficult; but it is not very important, since the treatment is identical. A separated epiphysis gives a smoother and less distinct grating than a fracture, and is apt to be followed by diminished growth in length of the bone. More difficult than the determination of the simple existence of fracture is the localization of the exact position and line of fracture. This is often of importance, and may be determinable only by careful fingering, accu- rate measurements, and close observation of changes in relative position of the prominences. Oftentimes the exact line of break is only to be inferred. The conduction of percussive vibrations from one end of a bone to the F. R A CT U R. E. S. 333 other will at times prove the non-existence of a line of complete fracture between the two points. Let the examiner grasp or place his fingers on one extremity of the bone, and then give the other several quick, sharp blows with his finger-tips or a small hammer. If the vibrations are distinctly conveyed along the bone, complete or impacted fracture is improbable. PROGNOSIS.—Closed fractures, if uncomplicated, usually do well. Open fractures are more serious than closed fractures of a similar degree of bone injury, only when infected by putrefactive or pyogenic bacteria. Oblique fractures usually leave some shortening of the bone, though this may be very slight and scarcely noticeable. Fractures in children unite more rapidly than those in adults; and fractures of the upper more quickly than those of the lower extremity. Small bones become united sooner than large ones. Some permanent stiffness is the rule after frac-. tures involving a joint. Many fractures will be followed by imperfect or bad results, notwithstanding the best surgical treatment. It is a common mistake to suppose that when the bone becomes united the patient will at once have a normal limb. Stiffness of the articula- tions, a dry and rough skin, Oedema and congestion, especially when the limb hangs down, and pain aggravated by changes in the weather are the most frequent sequelae of fracture. Many months may pass before they all disappear. Sometimes one or more of these symptoms is permanent. Stiffness, when not due to actual involvement of the articulation in the line of fracture, depends on the simultaneous occurrence of a sprain, hemorrhagic extravasation around or into the synovial sac, the entangle- ment of tendons in the Ossifying callus, or retraction of the ligaments and peri-articular tissues during the period in which the joint was kept immovable by the fracture dressing. This joint stiffness subsequent to fractures is most marked and more persistent in old persons and those of a rheumatic diathesis. QEdema results from pressure of the fragments or callus upon the deep veins, or from phlebitis and coagulation secondary to the injury. The coagula formed in the inflamed veins give rise in very rare instances to embolism. Sudden lividity or pallor, dyspnoea, precordial pain, and death occurring from three to six weeks after the receipt of fracture point to venous thrombosis and embolism. Less severe symptoms of the same character, followed by localized lung consolidation and cough, are due to detachment of a smaller embolus, and may terminate in recovery. If phlebitis is suspected, it is wise to keep the patient quiet and the limb at rest until absorption of the internal coagulum has occurred. Its frag- mentary detachment from the walls of the vein is to be feared. Cases of death after fracture have been attributed to what is termed fat embolism. It is supposed that the crushed marrow furnishes free fat globules, which, taken up by the veins and lymphatics, produce embolic plugging of the lungs, kidneys, brain, and other organs. The symptoms are similar to those of shock" and of the venous embolism ; but occur later than the former, and earlier than the latter. Not immediately after injury, as are symptoms of shock, but after the lapse of one or two days have symptoms attributed to fat embolism been observed. . Death, it is said, may occur very promptly from obstruction of the pulmonary circulation by these fat emboli; or it may be delayed for a Week or ten days and be due to inflammation of the lungs, brain, or kidneys, secondary to the embolic process. Some observers suggest that * Holmes's System of Surgery: Packard’s edition, vol. i. pp. 144 and 145. 334 D IS E A S E S A N D IN J U R IES OF B O N E S. traumatic delirium and hypostatic pulmonary congestion after fracture may be the result of fat embolism. Dxperiments show that disastrous results are only liable to occur when very extensive fat embolism is present. Otherwise the fat is eliminated, perhaps by the kidneys, for fat has been found in the urine. Subjects of chronic alcoholism and the aged are presumed to be specially liable to suffer severely from fat embolism, because the weakened heart cannot propel the fat circulating in the blood- current, nor are the damaged viscera able to resist the effects of the embolic injury. No secondary abscess occurs in fat embolism. The indication of treatment is to prevent the occurrence of fat embo- lism by keeping the crushed limb quiet and avoid further laceration of the marrow. If amputation is demanded by the extent of the injury, it should be done promptly before much fat is absorbed. Intravenous injec- tion of ether, as suggested by Packard, may perhaps be indicated. Fractures may be complicated with, or followed by, dislocation, syno- vitis, gangrene, caries, necrosis, injuries to viscera, laceration of arteries, veins or nerves, and delirium. These circumstances greatly affect the prognosis. Whiskey-drinkers and the aged seem especially liable to traumatic delirium after fractures. JRepair of Fractures. As has been shown is the Section on healing of wounds, repair of most soft parts results in a cicatricial tissue which is analogous to, but not identical with, the structure wounded. In bones, however, as in nerves, a much more perfect regeneration occurs. Indeed, the uniting bone, if examined sufficiently long after the time of fracture, has the microscopic structure of true bone. Bones are repaired by the same general processes as are other tissues. The cells of the periosteum and marrow, and those lining the Haversian canals and the lacunae of the bone multiply. By this proliferation is formed a mass of granulation tissue, which fills the spaces between the pieces of bone and sometimes infiltrates the parts around the bone. This new material gradually becomes ossified by the deposition of earthy salts at numerous points, and the subsequent coalescence of these Ossific centres. The time after fracture at which bony particles are first formed in the bond of union is probably two or three weeks. The transition from granulation tissue to bone is usually through the connective tissue stage; though occasionally the granulation material, at least in some parts, becomes cartilage before it is transformed into bone. Some of this new bone, which is at first spongy in structure, becomes compact; some of it becomes more rarefied, and some is entirely absorbed ; until, finally, if the fragments have been kept in correct apposition, the bone is so well restored to its normal condition that, even when the dried bone is sawn open, no line of fracture can with certainty be distinguished. In fact, the changes occurring in repair of fractures differ only in a degree from those observed in the normal growth of bone. The location and degree of in- jury and the relative position of the fragments modify the number of Nature's resources, and change the character and amount of the repara- tive work to be done. Hence must be described more minutely the various steps of repair in closed, in open, and in epiphyseal fractures; and under closed fractures the differences between fractures of the shafts R. E. PA I R O F. F. R A C T U R E S. 335 of long bones or portions of bone with a medullary canal, and fractures running into joints. After the shaft of bone is fractured the periosteum, torn and stripped up from the bone though it may be, often forms a sort of ragged sheath around the seat of fracture. Within the limits of this imperfect perios- teal sheath new tissue to unite the bone is principally deposited. The periosteum, the injured marrow, and the broken cylinder of compact bone all become inflamed and furnish cellular elements, which, mingling with the blood-clots and effused serum, form an inflammatory exudate which becomes granulation tissue. The bone is the least active and slowest in furnishing new tissue, because it normally has fewer cells of its own than the marrow and peri- osteum, but at length granulations appear on the ends of the fragments and finally coalesce across the gap. This granulation tissue filling up the space between the ends of the fragments and lying within the confines of the periosteum and other tissues surrounding the seat of fracture, has of course no firmness until Ossification begins. When it begins to be firm it is called callus. During this early period of repair the connective tissue in the structures outside of the periosteum is also filled with proliferating cells, and thus steadies the broken bone by glueing the adjacent muscles, tendoms, and fascias together. The granulation tissue formed usually ossifies in man as connective tissue without showing any cartilaginous stage; but when fractures in man are kept perfectly at rest the granulation tissue which lies between the frag- ments and around the bone may become cartilaginous before being ossified. In any event it requires weeks for the callus to gain the hardness of bone. Ossification through the cartilaginous stage is the common event in the lower animals. During this period the marrow callus, which has occluded the medullary canal like a plug, and the external callus have held the fragments firmly in position. These depositions go by the name of provisional or temporary Callus. As the interosseous callus—that is, the callus between the two cylinders of bone, called the permanent or definitive callus—becomes hard, the external callus, as well as the internal callus which lies in the medul- lary canal, is absorbed. Thus the surface of the bone is finally given its normal contour, and the medullary canal, which had been completely ºp in both fragments for some distance from the break, is reëstab- 1S [162Cl. Small pieces of comminuted bone may be imbedded in the callus and assist in increasing its bulk. These fragments, even if entirely denuded of periosteum, do not die, unless the fracture is infected with pyogenic germs or other septic organisms. Sometimes such pieces become necrotic and remain in the callus as foreign bodies, giving little trouble; though they are apt to cause prolonged irritation and interfere with union. If there is much displacement union is effected between the nearest lateral surfaces of the bone, the open medullary cavity is covered in by new Osseous structure, and the displaced ends of the fragments become round and smooth as in a stump left after an amputation. Fractures of short and flat bones and of the ends of long bones are not accompanied by injury of marrow in a medullary canal. The pro- Qess of union is, with the exceptions due to this fact, identical with that in the shaft of long bones. Unless there be much motion during the time of union, very little callus is found around the seat of fracture, and, therefore, the prominent oval mass felt in the form of fracture just de- 336 DIS E A SES AND IN J U R IES OF BONES. scribed is absent. This absence is probably due to the fact that the peri- osteum in these locations is less easily stripped up by the injury. Less laceration and less displacement therefore occur. Union is favored, more- over, by the broad surfaces of spongy and vascular bone which are in contact and by the less liability to motion from involuntary muscular spasms. Hence less callus is formed, for a large amount of callus usually means difficult repair because of great displacement or much motion. When the line of fracture invades the articular surface of a bone the deposition of callus differs from that described in fractures not involving a joint. The bony surface covered with cartilage and bathed in synovial fluid does not usually furnish granulation tissue and callus as do the parts of the bone which are covered with periosteum and surrounded by mus- cles and fascias. Hence when union occurs it is by callus furnished by the envelope of the extra-articular portion of the bone and by the fracture surfaces themselves. There is no ensheathing callus on the articular sur- face to aid in repairing the edge of the fracture there. The articular cartilage which is split by the same line of fracture does not unite; or if so the normal structure is replaced by cicatricial fibrous tissue only. As a result there is shown on the joint surface a groove in the cartilage or a line of uncovered bone to mark the position of the former fracture. Sometimes in injuries of this sort, as for example in frac- ture of the patella, where correct apposition has not been obtained, the bond of union is very imperfect, being mostly fibrous instead of osseous. Open fractures, if aseptic, unite in a manner identical with that which has been described in closed fractures. If suppuration occurs, the repair is slower, because the warfare between the cells and the microörganisms is followed by death of much new tissue as well as destruction of the sur- rounding bone, muscle, and fascia. Violent inflammation of a mycotic kind is added, therefore, to the simple traumatic inflammation of aseptic fractures. Repair, therefore, is antagonized, and open fractures, unless they are early converted into closed fractures by primary healing of the soft parts next the bone, require a long time to unite. Superficial areas of bone or detached splinters may become necrotic and greatly retard healing of the soft parts and union of the main fragments. If much bone is lost by necrosis or by the shattering force causing fracture, bony union across the wide gap may be impossible, because the ossific influence is not great enough. Fibrous union then occurs. Epiphyseal separations, or fractures, seem to unite as readily as true fractures. The union is said to be at once a bony one instead of by the normal epiphyseal cartilage as previously. The growth in length of the bone is retarded by this precocious union between the shaft and epiphysis. Agnew thinks that in some cases the epiphyseal cartilage at the other end of the bone acts in a compensatory manner by allowing an unusual length- ening there. Very little is known of the peculiarities of union in this form of injury. Fractures of cartilages, such as the costal and laryngeal, which tend to ossify with advancing age, unite as bones by a material resembling callus. TREATMENT.—The essential points in the treatment of fractures are the replacing of the displaced fragments as soon as possible, the prevention of recurrence of displacement, attention to the condition of the soft parts around the seat of fracture, and due consideration of the patient's general health. The surgeon's object is to obtain prompt union with as little deformity as possible. At times, unfortunately, more or less deformity is unavoidable, because of the situation and direction of the line of fracture. R. EPA I R O F F R. A. CT U R E S. 337 Every effort should be made, however, to make this as slight as pos- sible. After receiving a fracture of the upper extremity the patient can usually walk to the place of treatment if the injured limb is supported by his other hand or a sling. If the lower extremity is the seat of suspected frac- ture, walking should be prohibited, and the patient carried by four men on a stretcher, settee, or wide board. It is recommended by some writers that these carriers should not keep step, because so doing has, it is said, a tendency to impart a painful swinging motion to the litter. Other writers advise them to step simultaneously. It matters little which precept is followed if the litter is held steadily and given no sudden jars; especially is this so if the patient lies immobile and does not try to move his body and limbs so as to neutralize the vibratory movements of the stretcher. The patient must be carried in severe fractures of the upper limbs also if shock is great. A crude splint of board, twigs, straw, pasteboard, or any other material of sufficient rigidity to steady the fragments during transportation should be bound to the limb. This may be done outside the clothing. In fractures of the leg or thigh the opposite limb makes a good splint to which to bind temporarily the broken one. Hay, rags, or small pillows may be placed between the limbs before they are tied together. The bed for the permanent treatment of a patient with a fracture of a leg or thigh should preferably be a narrow one, so that the attendants can conveniently reach each side of his body. A firm mattress that will not Sag down under the buttocks is necessary. One made of hair and laid upon slats or woven wire is probably the best. The old-fashioned sacking bottom for supporting the mattress is undesirable. Patients accustomed to sleeping upon feather beds may be very uncomfortable unless they have softer mattresses than hair. In such cases a thin feather bed may be used if it is thoroughly supported by the framework beneath it. Good Springs under a heir mattress are not objectionable if they do not permit the upper surface of the mattress to become uneven. There is no neces- sity for a specially made fracture-bed, if the bed-pan and urinal are care- fully and intelligently placed when the contents of the rectum and bladder are to be voided. The sheet under the patient should be kept smooth; its edges may be tacked or tied to the sides of the bed. When a clean sheet is to be put under him it should first be folded or rolled up longitu- dinally for half its width. This doubled-up portion is to be carefully pushed under the right side of the patient while he is very slightly turned on his left side; then he is to be carefully turned on his back and slightly on his right side until a second person standing on the left side of the bed draws from under him the folded-up edge of the sheet. Very little move- ment of the patient is made when this method is adopted. . During long confinements to bed the sacrum, heels, and other points sub- jected to pressure should be washed frequently with equal parts of alcohol and Water, and every precaution taken to avoid the occurrence of bed- * .

Replacing the fragments in their normal relation, technically called Reduction or “setting,” should be attempted as soon as the patient has been conveyed to a convenient place. Early reduction—that is, reduction before the advent of inflammatory swelling—is nearly always demanded. t is less painful to the patient, and adjustment can thereby be more easily 22 .338 DISE ASES AND IN J U RIES OF BONES. and accurately accomplished than if the necessary manipulations are de- layed. Moreover, the subsequent inflammation and chronic muscular spasms will probably be less severe if the sharp points of displaced bone are prevented by reduction from continually irritating and wounding the soft tissues. When the case has not been seen until severe inflammatory action has stiffened the muscles and greatly distended the fascias and in- tegument by interstitial swelling, it'may at times be proper to delay reduc- tion until this condition has been relieved. Absolute rest of the part with the fragments in moderately good position should be adopted and accom- panied, perhaps, by antiphlogistic local treatment, and sometimes even by incision through the constricting skin or fascia. After the lapse of a few days accurate reduction may be effected. The manipulations necessary for accurate adjustment, if made when the limb was stiff and so swollen, might cause rupture of vessels or nerves, or by increasing the internal pressure lead to gangrene. It may be judicious, perhaps, to delay also when there is evidence that the principal artery or nerve has been torn by the original injury, because the consequent gangrene might be attributed by a court and jury to the early manipulations made for reduction. As a rule, however, fractures are to be reduced and dressed imme- diately; and only in exceptional instances should the surgeon be deterred from attempting accurate adjustment. -- When subcutaneous hemorrhage or inflammatory swelling endangers the safety of the limb by arresting circulation, as shown by coldness and numbness of the fingers or toes, free incisions should be made through the tense integument to permit the fluids to drain away and thus relieve the pressure upon the vessels and nerves. Great stress is laid upon this measure, as threatening gangrene may often be averted by several cutaneous incisions of two, three, or four inches in length. Reduction of displacement should be attempted even if the case is first seen several days or weeks after injury. More force will be required under such circumstances; but of this more will be said under the dis- cussion of Refracture of Deformed or Vicious Union of Fractures. Reduction is sometimes readily effected by merely relaxing the muscles tending to cause displacement, whereupon the fragments fall into place. At other times some additional pressure and manipulation with the fingers are necessary before the more or less numerous pieces of bone are pressed into correct apposition. In still other cases an extending force must be applied to the limb on the distal side of the fracture, while counter-ex- tension is exerted upon the other side of the seat of injury. By counter- extension I mean a resistance to the extending force so that the body will not be pulled in the direction of the force used to make traction on the overlapping fragments. Extension and counter-extension are to be made by grasping the limb above, and below the fracture, and pulling with one hand while the other resists or pulls in the opposite direction. In dealing with a large, heavy limb it may be necessary for the counter- extension and sometimes the extension also to be made by an assistant. Such duties are also entrusted to assistants when the surgeon needs his fingers to mould the fragments into position. Extension-traction should be steady, continuous and moderate, and exerted in the axis of the limb, No greater force than can be obtained by the firm grasp and strength of the surgeon or assistants should be applied to the reduction of a recent fracture. Pulleys are never justifiable. What is required is a firm, steady pull of moderate force that will tire out the contracted muscles. Anaesthesia is often desirable, as it relaxes spasm and prevents pain. In R. EPA I R. O. F. F. R A CT U R ES. 339 many cases ether has already been given to enable the surgeon to make a careful examination, therefore the reduction is at once effected and the fracture dressing applied before consciousness is regained. Extension overcomes shortening due to overlapping of fragments, but if there is lateral and rotary displacement, coaptation with the fingers and rotation of the limb should be added to the extension. These combined manipu- lations will usually correct the deformity. In impacted fractures and in open fractures with one fragment thrust through the integument, as through a button-hole, much difficulty may be found. When a portion of bone into which a muscle is inserted is broken off it is to be put and held in position by traction exerted against the muscle. Fractures of the olecranon and patella illustrate this point. Sometimes difficulty is experienced in properly and completely reduc- ing the fragments. This may be due to impaction, to a fragment being entangled in or thrust through muscles or fascias, to one fragment being locked behind another and held there by muscular tension, or to actual crushing and powdering of portions of spongy bone. Inability to obtain a firm hold on one fragment may also be a cause of imperfect reduction. If muscles or fascias prevent reduction, subcutaneous section with a teno- tome is justifiable to prevent permanent deformity from this cause. An incision of skin and muscles is not infrequently required in open fractures before reduction can be obtained and also to permit thorough disinfection of the wound cavity and to make provision for free drainage. Whenever replacement is difficult, an endeavor should be made to replace the fragments along a course the exact reverse of that which was given by the vulnerating force. The portion of displaced bone should retrace the steps by which it reached its abnormal position. After reduction has been obtained the limb should be compared with the sound side, and the test lines verified, to establish the correctness of the replacement. Swelling may make appearances deceptive. Great care in this respect is necessary in fractures near joints. Continuous extension by means of weights is often employed to overcome overlapping. It acts by gradually tiring out the displacing muscles, and thus effecting reduc- tion. It is the usual method in fractures of the femur. Closed fractures seldom require any lotions or other external medicinal applications. Lead-water and laudanum and similar remedies, applied to the skin, can avail little in relieving inflammation of broken bones and torn muscle. Immobility and freedom from muscular spasm are therapeutic agents of far more value than external lotions. After reduction has been satisfactorily accomplished, displacements may recur through the action of gravity, muscular contraction, or restlessness of the patient. The surgeon must guard against such recurrence by applying some form of fracture dressing, which will retain the fragments in Proper position. The best form of dressing will be that which corrects the tendency to displacement in the individual case, and, at the same time, steadies and immobilizes the limb. The special tendency to displacement Varies in each case with the line and position of fracture, and should be recºgnized before the form of dressing is decided upon. . There are occasions in which no retention apparatus is needed, but these *stances are rare. The confidence of the patient and greater safety º displacement are obtainable by adopting some mode of fracture dressing. Fracture dressings may be grouped under three heads: ( 1) Those which give moderate continuous traction, or maintain extension which was applied 340 DIS E A S E S A. N. D. IN J U R IES OF B O N E S. when the fracture was first adjusted; (2) those which, by virtue of their rigidity or fixedness, resist retraction ; (3) those which, by virtue of their inflexibility, prevent angular or lateral displacement by giving lateral support to the fracture. These forms may be combined in the treatment of a given fracture. The simplest apparatus is the best. The articles employed in dressing fractures are: roller bandages; padding, such as cotton or oakum ; adhesive plaster; splints of any rigid material, such as wood, felt, pasteboard; cotton fabrics stiffened with gypsum, silicate of sodium, or starch ; fracture boxes; and weights for making continuous traction. As a rule, no roller bandage should be applied immediately to the limb under the splint, for the inelastic constriction thus made may lead to gangrene, if unexpected inflammatory swelling occur, and is, at any rate, of no service. Bandaging of the distal portion of the limb, beyond the splint, tends to prevent odema there; which is often seen, because the fracture dressing, even when properly applied, interferes somewhat with venous return. It is usually preferable not to bandage even this portion of the limb. The oedema, unless excessive or accompanied by discomfort, is of no importance. In dressing fractures of the shaft of bones, the nearest joint above and that below should, as a rule, be made immovable by the splint, because motion allowed at such articulations may cause displacement of the approximated fragments. Splints, if not moulded to the patient's person, should be padded with a thin layer of cotton-wadding, so as to make equable and elastic pressure, and thus accurately conform to the contour of the limb. A board slipped into a long bag, afterward smoothly stuffed with cotton, makes a good splint. The splints after adjustment are to be held in place by spiral or reverse turns of a roller bandage, applied with sufficient firmness to maintain the apparatus in position, and thus make the limb rigid so that no motion can occur at the seat of fracture. The fingers or toes should usually be left uncovered that lividity, coolness, or Cedema, due to improper constriction, may be noticed. The turns of the bandage can be kept from slipping by painting a broad line of mucilage or silicate of sodium down the outside of the completed dressing, or by applying a marrow strip of adhesive plaster down its exterior so as to hold the folds of the bandage. Another method is to stitch the bandage to the covering of the splint. Before applying the fracture apparatus, the skin should be washed with soap and water and shaved. In open fractures this is exceedingly important. Anti- septic lotions are to be used in these cases freely, to destroy any germs which may have gained access to the wound. Sublimate (1 : 500 or 1: 1000) solution is probably the best; and can subsequently be washed out of the wound by a weaker solution. All recesses must be made aseptic, and drainage tubes used to drain all dangerous pockets. Counter-incisions are often demanded, and all devitalized parts should be trimmed away. In truth, the wound must be treated and dressed exactly as any other lacerated infected wound, and then have fracture appliances adjusted. Conformable splints of metal, felt or pasteboard, or moulded splints, such as will be described below, are far better than any form of carved wooden splint. A thin board may be made flexible transversely by cut- ting six or eight parallel longitudinal incisions in it, extending almost, but not entirely, through its thickness. A sheet of rubber adhesive-plaster may then be smoothly fastened over the uncut side, in order to strengthen the hinges made at the incisions when the board is bent. R E PA I R O F F. R A C T U R. E. S. 341 Moulded splints are a most desirable form. They are at first suffi- ciently soft to be accurately fitted to the inequalities of the limb, but subsequently become hard. Felt, gutta- ercha, and pasteboard may be thus FIG. 148. moulded after being made soft by heat or moisture. Strips of gauze or any woven fabric with wide meshes can be converted into excellent splints by saturating them with a watery mixture of gypsum, the so-called plaster-of-Paris. Ten to twelve of these pasty strips, one over the other, are applied to the limb while it is held in proper position. They soon become rigid by the “setting ” or hardening of the gypsum. Lateral or anterior and posterior splints of any shape may thus be made and held in position by roller bandages. If it is pre- £ § ferred, the limb may be encased in #º sheets or bandages of gauze saturated =º with gypsum. This method is that used | Fº in making, the so-called immovable # = dressings, which are often very valuable - É after the primary inflammation of in- WWW jury has subsided.

(STIMsoN.) what as a book, and thus become mov- able splints. They may be furnished with eyelets, and thus laced like a shoe when reapplied. The gypsum powder for this purpose must be kept dry, for, if it absorbs moisture, it will not “set.” It may be mixed with enough water to make a paste of the consistence of cream, which is rubbed into the gauze at the time of dressing the fracture, or the dry powder may first be rubbed into the meshes of the gauze and the gauze strips or bandages dipped into Water as needed. If gypsum gauze is not used at once, it should be pre- served in a dry place. The setting can be retarded by the addition of a little dissolved glue, of borax, or cream of tartar to the water, and hºstened by using hot water or adding salt. A little skill in cutting out V-shaped pieces of the sheets of gauze, and in overlapping the edges thus made when corners are to be turned, will enable the surgeon to make moulded splints to suit fractures in all regions. Such splints may be Varnished to prevent absorption of fluids, and strengthened by incorpor- *ting strips of zinc between the layers. In open fractures which have become infected, and are therefore Suppurating, openings may be made in the splints, so that the wound may be dressed without displacing the fracture apparatus. Strips of metal to strengthen the dressings, or wire *ings for suspension, may be incorporated within the layers. Reduction of overlapping fragments is sometimes best accomplished by 99ntinuous traction by weights. The displacing muscles are thus tired 9Mt, and their tendency to either tonic or clonic spasm overcome. The °ord carrying the weight passes over a pulley and is attached to the limb 342 D IS E A S E S A N ID IN J U R I E S OF B O N ES. by strips of adhesive plaster. The tendency to lateral displacement is then obviated by coaptation splints at the seat of fracture. This method FIG 149.

Bad fractures should be visited within a few hours after the original dressing, lest unusual swelling may have occurred R E PA I R O F F R A C T U R E S. 343 and rendered the dressings too tight. If, after the second dressing, no undesirable symptom has occurred and the limb feels comfortable, re- moval of the apparatus is not called for oftener than two or three times a week. Daily inspection of the patient should, however, be enforced for ten days or so, even if no change is made in the dressing. When the sur- geon takes off the splints the limb should be held by an assistant, who should firmly grasp it above and below the fracture and allow no motion or displacement. After the skin has been washed with soap and water, or with alcohol, the limb should be dried and carefully examined for abrasions or bedsores, due to pressure, and for any renewal of deformity. It should ever be recollected that absence of discomfort is not a token of absence of deformity. Dressings which allow the seat of fracture to be always under observation are therefore desirable, though it is not always convenient to adopt them. If no untoward symptom occurs within two weeks, change of dressing once a week is sufficiently often ; but the possibility of angular displace- ment, even so late as four or five weeks, must be remembered. Loosening of bandages or sinking in the bed may cause lateral or rotary movement at the seat of fracture. Retention apparatus may, as a rule, be discarded in uncomplicated fractures of the upper extremity at the end of from four to six weeks, and of the lower extremity at from six to eight weeks. The bones should be subjected to no muscular strain for two or three weeks subsequently. During this time, and often longer, slings or crutches are needed. The union becomes firm in children sooner than in adults. Persistent pressure of the splint or bed upon any bony protuberance is liable to cause a localized chronic sloughing of the skin and subcutaneous cellular tissue, technically called a bedsore. This result must be avoided by careful padding, frequent change of the points of pressure, and bathing the cutaneous surface with water or alcohol. A patient can often change his posture in bed without detriment if a rope, attached to the ceiling over his head, is allowed to hang within reach. Bedsores often occur without any sensation of pain or burning. The surgeon must look for them, and not be satisfied with a reply that there is no pain. If a dark spot is seen on the heel, elbow, sacrum, or other prominence, a bedsore already exists. The slough must be detached before the sore will get well. Hence, moist antiseptic dressings should be applied for a time. The ulcer remaining after the detachment of the slough is to be treated by antiseptic dressings to prevent suppuration, and possibly by applications, such as chloral in solution or ointment (gr. x to Bj), nitrate of silver and iodoform. The inflammatory symptoms at the seat of injury in closed fractures usually need no treatment. Correct apposition and prevention of motion are the essential features. The blebs that sometimes form on the surface may be let alone, unless they are large; then they may be punctured with a needle to allow the bloody or straw-colored serum to escape. Wrapping the limb in cloths saturated with lead-water and laudanum, before apply. Ing. the splints, is improper. Such measures do no good, and the dressings, acting as poultices, may cause blebs to arise which otherwise would not have appeared. Muscular spasm about fractures is best combated by morphia given by the mouth or hypodermically. Retention of urine re- quiring catheterization is not infrequent after fracture of the thigh. Abscesses, traumatic fever, delirium, tetanus, erysipelas, and other com- Plications, must be treated on general principles. Gangrene due to arterial rupture or thrombosis simultaneous with the fracture occurs at 344 D IS E A S E S A N D IN J U R IES OF B O N E S. times; it may also follow constrictive pressure from excessive inflamma- tory swelling beneath the skin and fascia. When the last condition is feared, free cutaneous and fascial incisions, as previously described, will relieve the tension by allowing gaping, and thus often avert the calamity. Injudicious bandaging has often caused gangrene. In gangrene from any of these causes it is usually well to wait for the line of demarcation before amputating. If, however, the destructive process is rapidly spreading, immediate amputation at a high point may be judicious. FUG. 152. \ W A. ** * º Suspended and fenestrated gypsum encasement for fracture of leg. Immovable or fixed dressings, which, however, allow no inspection of the fractures, are often used when the fracture has been reduced and there is no fear of swelling. They should not be employed in the early days of a fracture. It is much safer to wait until all inflammatory action has subsided and there is some solidity given to the broken bone by the beginnings of repair. The end of the second or third week is early enough for their employment. Encasements are made from bandages or cloths saturated with gypsum, silicate of sodium, or glue, as has been mentioned above in describing moulded splints. Before the immovable apparatus is applied the limb should be smoothly enveloped in soft flannel or a layer of cotton wadding. Then the roller bandage soaked in gypsum should be applied circularly to the limb, without being drawn at all tightly. Silicate of sodium solution may be used instead of gypsum. It dries more slowly than gypsum, but makes a more elastic encasement, which, when split, can rather more readily be pulled apart, so that the limb may be lifted out and examined. Such a split encasement then becomes a movable splint. I usually so employ the so-called fixed dressings. As the limb shrinks because of absorption of inflammatory deposits, the splint will become too loose and allow displacement of the fracture. It should then be removed and replaced by a new one, unless it is elastic enough to be opened, padded, and reapplied. Eyelets and laces may be inserted for the purpose of regu- lating the degree of constriction. The seat of fracture or wound may be left open to inspection by an opening in the encasement. Powerful shears are the best instruments for dividing fixed dressings which are to be removed, but a saw or knife may answer. Gypsum encasements may be softened before using the knife by applying muriatic acid along the line of proposed division. Fractures running into joints are apt to be followed by ankylosis be- T R E A T M E N T OF O PEN F. R A CT U R ES. 345 cause of the arthritis that arises secondarily to the bone injury. The joints adjacent to a fracture are usually kept immovable by the splints in order to prevent motion at the point of fracture. Hence, when the apparatus is finally removed these joints often show considerable stiffness, due to disuse for several weeks and to the inflammatory exudate among the muscles and fascias. Passive motion of these joints by the surgeon at the time of rearranging splints during the treatment of the broken bone is often insisted upon. Such motion, unless very slight, may displace the fragments. Hence, it has long been a mooted question whether the surgeon should commence these manipulations early or late. In any case where there is probability of passive motion displacing the fragments it should not be commenced until firm union has taken place. Four weeks is early enough in all these doubtful cases. If arthritis has occurred as a complication, absolute rest is indicated and passive motion will do harm. If no arthritis has occurred, the stiffness due to disuse can readily be overcome by passive motion at a later date when there is no risk of inter- fering with bony union. Then the patient can supplement the passive motion employed by the surgeon by rubbing and moving the limb with his own hands or pulling against a resisting force. Passive motion which is followed by pain and tenderness of the joint is usually deleterious, for it means that arthritis exists. FIG. 153. Shears for cutting through gypsum dressing. When a fracture is complicated by dislocation of a neighboring joint, the surgeon should endeavor to reduce the dislocation at once. " The necessary leverage may often be obtained by applying such temporary Splints as will steady the broken bone. Afterward the same or other fracture dressings may be utilized for the treatment of the fracture. Treatment of Open Fractures. The treatment of open fractures—that is, of fractures complicated by *Wound, leading to the seat of fracture which communicates with the * -Varies with the character of the injury. The indications are to replace and retain the fragments in apposition and obtain rapid healing of the wound. The last indication is usually, though not always, Possible of fulfilment if the wound is promptly made aseptic and kept 59. Hence, the surgeon, after reduction of the fracture, should cleanse the wound with antiseptic washes, such as corrosive sublimate solu- *% (1 : 500 or 1000), and treat it so as to avoid virulent consecutive inflammation due to infection. When a portion of the bone protrudes through the skin, manipulation, relaxation of muscles, enlargement of º wound, tenotomy, and resection of the ends of the fragments should * Practised to accomplish replacement. . When the bones constantly 346 D IS E A S E S A N ID IN J U R I ES OF B O N ES. slip out of apposition resort should be had to wiring them together by means of holes drilled obliquely through the extremities, or by driving sterilized bone pins or steel nails into the Osseous tissue and twisting the wire around them. Loose splinters and all foreign bodies should be picked out of the wound. Portions of bone still maintaining periosteal attachments should be permitted to remain. Fractures com- plicated with wounds are almost certain to suppurate unless they are managed with rigid antisepsis, because they have been infected before they are seen by the surgeon. They should be thoroughly washed out by antiseptic lotions after the surrounding parts have been scrubbed with soap and water under anaesthesia, and only closed after provision for free drainage has been made by means of counter-incisions and drainage-tubes. All dirt and foreign material must be removed. The method of render- ing such injuries aseptic has been described under the Treatment of Wounds; for an open fracture is a lacerated wound of soft parts and bone. When washing out an open or compound fracture with the anti- septic solution, provision should be made for the outflow of the blood- stained fluid, so as not to leave poisonous fluid in the cavity on the one hand or to fail to get rid of septic bacteria on the other. Counter-open- ings or enlargement of the original wound may be demanded for this object. Intramuscular or subcutaneous lacerations often extend up and down the limb a long distance from the seat of fracture. These may re- quire long incisions in order that efficient disinfection may be accom- plished. After thorough irrigation, the wound is to be dressed on general principles with a voluminous antiseptic gauze dressing. If the attempt to get primary union has failed, the first indication of suppuration is to be followed by immediate opening, sterilization, and drainage of the wound. The surgeon's nails, hands, and instruments must be sterilized before undertaking these manipulations. Failure to get primary union of the soft parts is evidence that the wound was not made sterile. Ordinary fracture apparatus, to maintain proper position of the frag- ments, must next be applied outside of the gauze dressings. When a simple fracture shows signs of becoming open because of cutaneous sloughing, an effort should be made to prevent as long as possible the separation of the eschar by keeping it aseptic. Some open fractures demand immediate amputation, because the injury is so severe that the sloughing sure to follow will probably prove fatal. If, after an attempt to save the limb, unexpectedly severe symptoms occurred, it was formerly considered to be usually better to delay ampu- tation until suppuration and sloughing had been fully established. In other words, intermediary amputations in such injuries were apt to be disastrous. Immediate amputations—that is, those done as soon as reaction from shock had occurred, and those done after the lapse of about ten days, when suppuration was fully established—were thought more likely to be followed by recovery. This is no longer a rule, as antiseptic methods have altered the clinical history of all wounds, and will reduce the amount of suppuration and the degree of septic poisoning in those cases where the impossibility of obtaining a sterile wound has prevented primary Ullſ]] Ol). Antiseptic methods have enabled surgeons to save many limbs sub- jected to open fractures, that under previous methods of treatment would have required immediate amputation to save life. Almost any open frag- ture in which the tissues are not absolutely devitalized can be successfully treated if made perfectly sterile and kept so. I have been astonished at UN UN I T E D F R A CT U R E O R P S E U I) A R T H R O S I S. 347 my success in these cases. Amputation is usually required in railway and other injuries which cause crushing of the bones and pulpefaction of the soft parts. Similar treatment is often demanded when the main artery has been opened by the injury. In the upper extremity conservative sur- gery is attended with less risk to life than in the lower limb, , Moreover, the fact that artificial legs are very serviceable, while artificial hands and arms are practically useless, argues something in favor of not taking too much risk by trying to preserve a doubtful leg. It must be remembered, however, that amputations high up in the thigh for any cause have a somewhat high death-rate. Open fractures involving large joints may often be treated by primary or secondary excision of the joint instead of amputation. Gunshot fractures involving joints are an exceedingly serious form of open fractures. If in open fractures running into joints the limb is to be saved, antiseptic cleansing, free drainage, perhaps by many counter-openings, antiseptic irrigation, and in extensive fracturing, ex- cision must be the resorts of the surgeon. Excision may sometimes be delayed and performed as a secondary operation when it can be better determined how much bone must be sacrificed. Rigid and thorough pro- vision for escape of all wound fluids must be insisted upon in all these injuries. Drainage is an essential factor in open fractures. Umunited Fracture or Pseudarthrosis. PATHOLOGY..—It is occasionally found that some degree of mobility and pain on motion persists after the lapse of what ordinarily would be sufficient time to cause consolidation of a given fracture. Such instances are denominated cases of delayed union. If successive weeks or months pass without union occurring at the seat of fracture, the condition is un- united fracture, false joint, or pseudarthrosis. Delayed union is usually the result of deteriorated general health, while false joint in almost all instances depends upon some local condition pertaining to the fragments themselves. Many cases of delayed union finally terminate in complete consolidation without any special treatment beyond building up the pa- tient's health. False joints, however, whether sequences of delayed union or cases showing from the beginning no tendency to union, persist, and require either the adaptation of apparatus to supply the normal rigidity of the limb or active and judicious surgical treatment. Efficient appara- tus is more easily obtained for non-union in the upper than in the lower limb, because of the weight-sustaining function of the latter. It is not customary to apply the term ununited fracture to the fibrous union that frequently occurs when short, spongy bones and the spongy ends of long bones are broken, or when prominences for muscular attach- ment are torn loose. These fractures would probably unite by ossific deposition, as other fractures do, if correct apposition was obtained and maintained. They actually, therefore, are cases of unuited fracture, though not called so. The bond of union holding the fragments together ºfter healed fracture occasionally undergoes softening and absorption during the progress of phlegmonous inflammation of the limb, scurvy, or other grave disorder. It is manifestly improper to apply the term un- united fragture to this condition when it occurs subsequent to complete *ion of the Osseous lesion. Atrophy of the bone itself sometimes occurs after fracture. Ununited fracture is a comparatively rare condition. The cases may 348 D IS E A SES A N D IN J U R IES OF B O N E S. be divided into three classes: 1, those in which there is no bond whatever; 2, those in which there is more or less successful attempt at union by means of bands of fibrous tissue and nodules of bone; 3, those in which a crude joint is formed as exhibited by cartilaginous material on the apposing surfaces of bone, synovial fluid, and a capsule. The first and third varie. ties are very unusual. The second form is that usually found when un- united fractures are dissected. The length and disposition of the fibrous bands vary in accordance with the relation of the fragments. There may be a mass of callus partially ossified and little fibrous tissue; or little callus with bands of fibrous tissue uniting the fragments somewhat like interOsseous.ligaments. This kind of non-union gives a flail-like limb if the bands of fibrous tissue are long. It is more movable than the form described as having a joint-like structure. CAUSES.–Syphilis, pregnancy, advanced age, acute diseases, and other Sources of physical deterioration and malnutrition have been described as causes of ununited fracture. They apparently, however, have little influ- ence in giving rise to non-union, though delayed union may perhaps be due to them. Non-union is nearly always the result of a local cause, and this local cause is usually mechanical. The most frequent agencies are: (1) unfavorable relation of parts, such as great separation of the frac- tured surfaces by reason of displacement, actual loss of substance, or necrosis; (2) defective treatment, by which immobility of the fragments is not secured; (3) portions of fascia or muscle, and bullets or other foreign bodies lying between the fragments; malignant and other growths in the same location. Destruction of the nerves coming from the trophic centres in the lower part of the spinal cord, or of the centres themselves, has been with apparent reason assigned as a cause of ununited fracture or pseudar- throsis. It is also stated that softening or absorption of callus may follow the too early use of a broken limb. This occurrence is doubtless the result of motion at the seat of a partially ossified callus union and comes under the head of defective treatment mentioned above. DIAGNOSIS.—The diagnosis of ununited fracture is made by preter- natural, and, in most cases, painless mobility existing long after the time for consolidation has passed. Near a joint such mobility may simulate the normal articular movement; or, a joint with relaxed ligaments may simulate ununited fracture. The character of the defective union is often obscure. If it is simply delayed, an elastic mass of callus, which is the seat of pain on strong passive motion, will probably be discerned by palpation. If a crude joint has been developed, no callus and no pain will be found ; nor will the flail-like mobility of long fibrous attachment exist. Careful palpation and puncture with long needles will at times determine the position and shape of the fragments. TREATMENT.-The treatment of delayed union consists in friction of the limb, change of air, nourishing diet, and the administration of alka- line phosphates and carbonates, and of tonics. A few additional weeks under good hygienic circumstances is all that is usually demanded. Ununited fractures, whether fibrous or articular, demand much more active measures, of which the milder forms, however, should first be employed. Rectification of any displacement that seems to interfere with union should be accomplished, after which the immovable gypsum dressing should be applied and worn for a month. If any increase of consolidation is observed this dressing should be continued for several months, during which time the patient may go about on crutches if it is the lower limb which is the seat of injury. If the part becomes painful UN UN I T E D F R A CTU R E O R P S E U D A R T H R O SIS. 349 from excoriation, the encasement may be split and laced or removed, and a new one applied. . The latter method is probably the better. During this period the hygienic measures noted above for delayed union should be adopted. The application of the descending constant current has been recommended, but is probably valueless. Failure to accomplish anything by these plans necessitates the adoption of operative measures, unless more support by apparatus to give rigidity is acceptable to the patient and surgeon. º º The operative plans aim either at setting up inflammatory action at the seat of non-union, and thus stimulating functional activity; or, at con- verting the old ununited fracture into a recent one with freshly sawed SUlT- faces in apposition. Violent bending and rotation, such as will tear apart the fibrous connections and cause the ends of the fragments to be rubbed upon each other, will often be followed by consolidation. These manipu- lations may be repeated daily until tenderness and swelling follow. º Upon the appearance of these symptoms the limb should be immobilized in splints and treated as a recent fracture. As a rule, the fibrous union can at one sitting be torn up and the ends rubbed with sufficient degree of force to cause the advent of tenderness on the following day. The bones may be bent at right angles and extensively rotated and extended without endangering the safety of vessels or other tissues. To be ol service the manipulation must be thoroughly done; usually under influ- ence of an anaesthetic. When the operation does not succeed in causing deposition of callus and consequent union, subcutaneous drilling of the fragments may be tried. A bone drill is introduced through a small puncture in the skin and the ends of the fragments perforated in various directions. Afterward retention apparatus is applied. Ostitis is the result of this treatment, and may be followed by union. A similar ostitis has been induced by driving an ivory peg through or into each frag- ment, in which a hole has been previously made by means of a drill. The fibrous bands should previously be ruptured by passive motion. The pegs, which do not pin the bones together, are withdrawn in a few days when pain is felt in the Osseous tissue. A better plan, when practicable, is to bore holes into the fragments and pin them together by means of metal screws or pegs of ivory or bone. These may be cut or broken off close to the surface of the bone, and the tissues allowed to heal over them. Thus the fragments are held in position while productive ostitis furnishes callus to join them firmly and permanently. The ivory and bone pegs will be- come absorbed, the steel screws encysted. If the surgeon prefers, the screws or pegs may be allowed to project from the wounds of entrance and be withdrawn in two or three weeks, when consolidation is partly accomplished. This method is more apt to permit purulent infection and cause suppuration than the former, but may in some instances be prefer- able. The bone pegs are readily made from bone knitting needles, The most radical operation for ununited fracture is resection of the Wounded ends of bone. It makes an open fracture, but it is often the only method that will lead to a cure. This is especially so in cases where the non-union has caused the formation of a joint-like structure, and where the failure of union is due to dead bone or portions of muscle be- tween the ends of the fragments. The danger formerly belonging to this prºcedure is obviated by the methods of antiseptic surgery. Suppuration will seldom occur. A longitudinal incision is made, the ends of bone turned out and sawed off after saving as much as possible of the perios. teum, the limb put up in splints, and the wound treated antiseptically, as 350 D IS E A SES A N I) I N J U R IES OF B O N E S. in open fractures. The chisel, bone cutters, or saw may be used to remove the pieces of bone. Sometimes the ends may with advantage be fastened together by wire, sterilized bone pegs or screws, as in accidental open fracture. These substances may be cut off short and left in the wound, or be taken out in about three weeks. As little as possible of the bone should be sacrificed, only enough to give a broad, fresh surface of contact. Sometimes shoulders are cut so that the fragments may be interlocked or mortised together. Transplantation into the gap of small portions of bone from the human subject or from lower animals has been prac- tised with apparent success. It may happen that the excision of the ends of the fragments with pegging or wiring them together will, if done anti- septically, produce so little irritation that there is not enough productive inflammation to cause union. When this is feared, it is best to leave the wound in the soft parts open and plug it with antiseptic gauze, so that more irritation will be induced and union occur only by second intention. The outside dressing must be carefully applied, so as to prevent putrefac- tive or purulent infection. Death frequently occurred formerly after operations for ununited fracture from suppuration and sepsis. Amputation is not to be considered in cases of ununited fracture, except under exceptional circumstances, and when resection or one of the other operations has been followed by gangrene or diffuse suppuration. Deformed or Vicious Union of Fractures. PATHOLOGY..—Absence of proper treatment in cases of fracture often gives rise to deformed union, because callus will be furnished and consoli- dation of the bony structures usually occurs, even when the fragments have not been placed in correct apposition. Great disability may thus result, especially in the lower limb. Angular deformity or overlapping will cause shortening; the presence of an abnormal projection near a joint may interfere with flexion and other articular movements. Change in the long axis of the fragments and rotation may cause the weight of the body to throw unusual strain on the lateral ligaments of the knee and ankle, and produce secondary deformity in these situations. Vicious union may also give trouble by causing painful pressure upon nerves, or by inducing ulceration of the skin over projecting portions of bone. In the forearm pronation and supination may be obstructed by bridges or masses of callus attached to the radius and ulna. Deformed union some- times allows muscles and tendons to become entangled in the callus, and thus, if not remedied at an early day, gives rise to permanent impairment of muscular action. There are two methods of freatment: subcutaneous refracture, and divi- sion of the deformed union. The former is less dangerous than the latter, and, in fact, is practically devoid of danger, because it merely creates a closed fracture which unites promptly, and there is naturally much less dis- turbance of the soft parts than in similar fractures of accidental origin. Hence little reaction follows. Experience shows that refracture or rup- ture can be done as late as six and twelve months after consolidation has occurred, and that with proper precautions the bone need never be broken at other than the seat of original injury. Gradual bending and attempts to soften the callus by applications or medication are a useless waste of time. Angular deformity is the variety that most frequently demands cor- DE FOR MED OR VIGIOUS UNION OF FRACTURES. 351 rection. Fortunately it is also the most amenable to improvement. Refracture of malunion a few weeks old can usually be accomplished by seizing the limb firmly with the hands and forcibly bending the bone at the seat of the old fracture. The bending is generally made in such a way as to attempt at once straightening the bone. Sometimes it is better to bend first in the direction of the flexion, as is done in breaking up an ankylosed knee. It may be necessary to place a fulcrum, such as the operator's knee or a block of wood, against the convex surface of the angular deformity. Another method is to have the limb projecting over the edge of a table and steadied upon the table by an assistant, while the operator takes the distal end and suddenly throws his weight upon it. A sudden force is much more effectual than gradual bending, which will be found unavailable in all but recent cases. It is often well to bind a straight splint to the limb below the seat of proposed refracture and another above it, but neither of them should overlap the mass of callus. These splints prevent motion and strain of the joints, give the operator more leverage, and avoid the remote possibility of fracturing at any other than the desired point. Strong extension and counter-extension by means of pulleys may be applied at the time the cross-breaking strain is exerted. The attachment of the pulley-rope can be satisfactorily made by the notched extension plate of Dr. R. J. Lewis. When shortening is great it may be well to continue anaesthesia and excessive extension for an hour or so after refracture, to gain as much length as possible before dressing. Some form of osteoclast, such as Taylor's or Rizzioli's, may be employed in very firm consolidation." FIG. 154. Levis’s notched extension plate. When the deformity depends upon lateral application of the two bony cylinders rupture must be attempted by flexion across the bond of union, combined with rotation in the axis of the limb, and strong extension and Counter-extension. These cases are not as amenable to treatment as angular malunion. Division of the deformed union should only be employed when correc- tion by refracture is impossible, because it creates an open fracture, and may lead to suppurative dangers from neglect of antiseptic precautions. An incision in the soft parts is made, and through this a small chisel or saw is introduced. The callus is then divided, the deformity corrected, and dressings applied as in open fractures. If simple division of the bony tissue will not permit adjustment, or if the tissues of the concavity are very tense, . wedge-shaped piece with its base at the convex surface may be €XCISecl.

Projecting spurs of bone, acting deleteriously because of pressure or their position near joints, may be removed with the saw or cutting forceps, very much as an exostosis, and usually with as little risk.

Taylor's osteoclast. treatment of malunion in the forearm interfering with promation and supination is surrounded with a good deal of difficulty. In some cases division or excision of callus is justifiable. SPECIAL FRACTURES. Fractures of the Vertebrae. Fractures of the vertebral column derive their chief importance from the damage to spinal cord and nerve trunks, which so often accompanies them. The spine requires solidity and flexibility in order to give support and movement to the head, trunk, and limbs; but its protective function, as regards the spinal cord, is even more essential to life and health. As in cranial, so in spinal fractures, the surgeon is more anxious concerning the integrity of the contained nerve elements than he is about the Osseous lesion. The vertebral column quite frequently sustains fracture from an in- direct violence which tends to produce over-extension or over-flexion of its normal curvatures. For example, a man falling from a height on his head or buttocks, or being crushed under a weight falling from above upon his head or shoulders sustains a fracture of the spine, because the limit of flexion or extension has been exceeded and the bony Segments are crushed or lacerated by the force. The fracture in such instances usually F. R A C T U R ES OF T H E W E R T E B R AE. 353 occurs where a movable portion of the column joins a more rigid portion, because here the sudden check to movement occurs. Hence, clinical ex- perience shows spinal fractures from this form of injury to be more frequent near the dorso-lumbar junction and in the vicinity of the fifth and sixth cervical vertebrae. PATHOLOGY..—The bodies of the vertebrae seem to suffer from fracturing forces oftener in the lower than the upper region ; while the arches are more frequently broken in the neck than elsewhere. Fracture of the spinous process occurs most often in the dorsal region. The lines, of fracture and the number of vertebrae involved depend upon the direction and degree of the force. Dislocation often accompanies, the fracture. Indeed, the two conditions are frequently indistinguishable except by post-mortem examination." Contusion, compression, and laceration of the spinal cord may be caused by displacement of the fragments. It requires considerable dis- placement to pinch the cord, for the canal is much wider than the spinal cord and its membranes. As the cord ends at the level of the first or second lumbar vertebra, fracture below this point can only compress the leash of nerve roots and branches called the cauda equina or horse- tail. Hemorrhage from the venous plexuses between the bony wall and the dura mater may be a result of the fracture. Such hemorrhage and inflammatory products may exert pressure on the nervous structures. Extravasations of blood into the cellular tissue in front of and around the spinal column often occur, and after a time may appear upon the surface of the face, chin, neck, and other regions. SYMPTOMs.—There is often in vertebral fractures no noticeable de- formity, preternatural mobility, or crepitation. The diagnosis must then depend upon the rational symptoms, which are, for the most part, refer- able to lesion, either primary or secondary, of the spinal marrow. De- pression may sometimes be discovered over a fractured spinous process or vertebral arch, or an angular prominence may be perceptible posteriorly after crushing fractures of one or more vertebral bodies. Unusual mobility may be observed at times, especially in fractures of the cervical region, and occasionally movable regions may become more or less immobile, because of spasmodic contraction of the muscles about the fracture, or because of interlocking of the fragments. Crepitation may be present, absent, or discernible only by the patient. The manner in which the spinal column is bound together with ligaments and surrounded with muscles often prevents the discovery of these symptoms of fracture, even When extensive fracturing exists. Localized pain, increased by manipu- lation or motion, is usual in fracture of the vertebrae, but is not diagnostic of the character of the injury. In spinal fractures intelligence is unimpaired, except, perhaps, during the stage of shock. Paralysis of the parts supplied by the nerve branches, leaving the cord at or below the seat of injury, is a common symptom. In locating a fracture by this symptom it must be recollected that the nerve roots and branches run obliquely downward within the vertebral canal, and do not escape at the inter-vertebral openings corresponding to their Points of origin from the medulla. For example, paralysis of the legs and trunk, extending as high as the distribution of the first lumbar nerve, Would suggest that the fracture was located about the eleventh or twelfth dorsal Vertebra. The paralysis is usually both motor and sensory, and is Fºtial or complete, according to the character of lesion in the cord. When complete, the area of cutaneous insensibility is sharply defined. s) & 2. C. 354 DIS E A S E S A. N. D. IN J U R IES OF B O N E S. Pricking the surface with the point of a pin is an easy method of deter- mining the paralyzed area, and of estimating its increase as the cord becomes involved in inflammatory processes extending upward. The lower limbs alone will be motionless, if the fracture is below the origin of the brachial plexus. Otherwise the arms will be paralyzed also. There is usually no reflex contraction upon pricking or pinching the paralyzed limbs, and electrical contractility is soon lost. If the paralysis is incom- plete, hot and cold sensations may be distinguished. Sometimes cutaneous hyperaesthesia exists. Darting pains may be felt in the limbs when the partially paralyzed extremities are moved, though spinal pressure elicits no such symptom. The occurrence of such pains is under some circumstances a sign of returning innervation, and, therefore, a symptom of beginning improvement. Tonic or clonic spasms of the muscles are occasionally observed, and may be excited by manipulation, drafts of cold air, and similar irritants. The paralysis may not be present immediately after injury, but may supervene upon movement causing displacement, or arise from an intraspinal hemorrhage or the development of inflammation of the cord or its membranes. The superficial branches of nerves coming from the medulla above the lesion may supply the integument for a con- siderable distance below the injury, and thus deceive the surgeon as to the location of the fracture. As a result of the paralysis retention of urine occurs, to be followed after a time by overflow and incontinence. Alkaline fermentation of the urine within the bladder, and cystitis, soon supervene. Constipation, fol- lowed by incontinence of feces, is another paralytic phenomenon. Tym- panitic distention of the abdomen also takes place. In fracture of the upper regions the respiratory distress due to paralysis of the abdominal and other muscles of respiration is increased by this tympanitic distention, which prevents full descent of the diaphragm. Bedsores appear, often within two or three days, because the insensitive and motionless limbs do not change the points of pressure. The probable occurrence of bedsores is increased by the difficulty of keeping the sheets free from urine and feces, which are evacuated unconsciously. Persistent vomiting and marked elevation of temperature of the palsied region have been observed in fractures of the upper part of the spine. Priapism, more or less marked, is a common accompaniment of spinal fracture. It seems to diminish in frequency as the injury occurs lower in the vertebral column. Seminal emissions sometimes take place. In- troduction of the catheter to relieve the distended bladder, though not felt by the patient, may increase the erection or cause a partial erection if none was previously present. I am not cognizant of erection of the clitoris having been noted in females suffering from fracture of the spine. Analogy suggests its probable occurrence. A careful clinical study of the symptoms of spinal injuries will lead to a more correct localization of the seat of fracture than is possible by a cursory survey of the case. Spinal localization, as cerebral localization, needs more consideration at the hands of surgeons. This matter has been referred to in the chapter on Intraspinal Inflammation. Brain lesions may coexist with spinal fractures and complicate the problem. Fractures of the atlas and axis are very dangerous because they are apt to involve the integrity of the medulla oblongata, with its numerous nerve centres, and are above the roots of the phrenic nerves which, going to the diaphragm, are the chief respiratory nerves. If cord injury occurs and death is not immediate, the paralysis will almost certainly involve F. R A C T U R ES OF T H E W E R T E B R AE. 355 the trunk, arms, and legs. Fractures below the axis and not lower than the second dorsal vertebra are of unfavorable prognosis, because this in- cludes the roots of the origin of the phrenic nerves and brachial plexuses. The phrenic nerves emerge between the third and fourth cervical verte- brae, coming from the fourth cervical pair alone or having accessory roots from the third and fifth cervical nerves. The brachial plexuses are de- rived from the fifth, sixth, seventh, and eighth cervical and first dorsal nerves. Hence injury at, or no higher than, the fourth cervical vertebra will involve the innervation of the arms, but will allow the functions of the phrenic nerves to go on unless intraspinal hemorrhage or inflammation extends above the level of the fracture. Lesion of the cord above the fourth, sufficient to induce paralysis, will probably involve the phrenics and cause death promptly by respiratory failure due to paralysis of the diaphragm. When the other muscles of respiration, but not the diaphragm, are paralyzed, the character of breathing is peculiar. In- spiration occurs from diaphragmatic action alone and expiration from the abdominal walls and viscera pressing the diaphragm up. Expiration is consequently passive and feeble; hence the patient is unable to talk, cough, or sneeze forcibly and the lungs become clogged with mucus. Change of posture, by changing the pressure, may alter the complexion of symptoms. The character of the lesion in the cord determines the extent and nature of the symptoms. Palsy may affect one or both arms or only certain groups of muscles in the upper extremities. So the phrenic nerves may be slightly involved and slow the movement of the diaphragm in- stead of stopping it entirely and causing immediate death. Slow pulse, some cyanosis, delirium, and coma may be observed in the clinical history of fracture of the cervical vertebrae. Irregularity in the posterior wall of the pharynx may be observed if the cervical vertebral bodies are fractured or displaced. The paralysis of the legs, bladder, and rectum will occur in a manner similar to what is observed in fractures lower in the dorsal region, and in the upper lumbar vertebrae. PROGNOSIS.–In spinal fracture accompanied by paralysis the prognosis is unfavorable. Many cases die from spinal meningitis and myelitis and from the exhaustion of bedsores and cystitis. Cases do at times re- gover, but usually with considerable disability from loss of power in the legs and imperfect control of the bladder and rectum. The lower the seat of fracture the better the chance of recovery both as to life and to function. In cases which finally prove fatal, life is the more prolonged as the site of fracture descends the spinal column. In patients who finally recover more or less completely, sensation usually returns in the palsied region before motion. TREATMENT.-The management of spinal fracture usually resolves itself into catheterizing the bladder, preventing the occurrence of bed- Søres, and treating the spinal injury and inflammation in accordance with he rules laid down in the section on Diseases of the Nervous System. The patient should be transported and turned when in bed with great care. Especially in cervical fracture is this caution important, for there unexpected displacement from movement is more liable to happen. Sudden death from pressure upon the medulla may be thus induced. It has been suggested in fracture of the neck to keep the patient lying on his back with his head supported in a hollow made in a bag of sand. In fracture lower down gypsum jackets have been applied after etherizing *nd suspending the patient. The suspension gives an opportunity to 356 D IS E A SES A N ID IN J U R.I ES OF B O N E S. reduce the fragments by extension and direct pressure, and the jacket prevents subsequent displacement. The jacket is best made by soaking at one time several sheets of gauze cut the proper shape, in a paste of gypsum and water, and applying these layers around the trunk. If displacement is discoverable and paralysis present, reduction of the displaced fragments by means of extension, rotation, and pressure is justi- fiable. Especially is this so because of the frequent impossibility of diag- nosticating dislocation from fracture. The urine should be drawn with a soft-rubber catheter three times in the twenty-four hours, beginning as soon as retention occurs, which is usually at once. The surgeon must look to this, for the patient will feel no pain from the distended bladder. The dribbling that takes place from overflow when the bladder is distended to its utmost may deceive the nurse, who will think the urine is being passed incontinently. This incontinence of retention calls for catheterization. Proper and early use of the catheter delays the advent of cystitis. When true incontinence occurs the catheter is no longer demanded. When cystitis has supervened the bladder should be washed out daily or every other day with warm water passed through a rubber catheter from a reservoir held a foot above the patient's abdomen. The solution may be medicated as is detailed in the section on Cystitis. Spinal fracture rarely gives rise to pericystitis, pelvic abscess, or sloughing of the bladder wall, but may do so. Bedsores are to be avoided by using an air- or water-bed and keeping the patient clean. Careful turning to change the points of pressure is often essential. A cheap water-bed can be made by filling a trough with water and tacking a rubber blanket over the top. Trephining, sawing, or cutting away the arches of the vertebræ for the purpose of removing pressure on the spinal marrow has been attended with some success, and should be adopted more frequently than has here- tofore been the case. To a great extent the want of success is owing to the fact that the injurious pressure is often caused by the displacement of the vertebral bodies, which, being in front, are not easily reached; and to the circumstance that operative interference is delayed. Reduction by extension applied to the patient's shoulders and legs, and operative relief of spinal cord pressure should be undertaken immediately after the receipt of injury. Perhaps the cord may at times suffer pinching by a temporary displacement of the fragments at the moment of accident. In such cases operation would be of no service, because the bones have resumed their normal relations. Operation is always justifiable if the fracture is definitely located and there is no reason to suspect irrelievable displacement. It must be attempted under most rigid asepsis or antisepsis. Bromide of potassium, cupping and ice to the spine, belladonna, ergot, iodide of potassium, Strychnia, massage, counter-irritation, and electricity are therapeutic resources to be employed in accordance with the direc- tions given under the treatment of Intraspinal Inflammation. Fractures of the Cranium. PATHOLOGY..—Cranial fractures differ from those of other regions in not being subject to displacement from muscular action; in requiring no retentive apparatus to maintain apposition of fragments, and in having mo tendency to non-union. Their importance and interest, moreover, centre, not in the damage dome to bone, but in the associated injury F. R A C T U R ES OF THE C R A NIU M . 357 sustained by the brain and its membranes. The cerebral injury may be contusion or laceration due to the same force that broke the bone; or it may be inflammation and irritation occurring secondarily to de- pression and splintering of the bone, and to bacterial infection through the fissures in the bone, or to overgrowth of callus at the time of repair. It should be remembered that the walls of the cranium consist of two tables, separated by a greater or less amount of soft and vascular cellulated bony structure called the diploé. The inner table is nearly always more extensively broken than the outer, because the fracturing force, as a rule, is supplied from without inward. The greater shat- tering of the inner table is especially marked in comminuted fractures. The thinnest parts of the cranial wall are in the orbital, ethmoid, squa- mous, and inferior occipital regions. The frontal region is remarkable, after the age of infancy, for the existence in it of large cavities, the frontal sinuses, between the two tables of bone. The prognosis in cranial fracture is favorable, provided the brain sus- tains no primary or secondary damage. Under opposite conditions death often occurs. Epilepsy and insanity sometimes follow as remote results, especially in fractures during childhood. Union is rather slow because the callus is FIG. 156. furnished by the osseous tissue rather than the external periosteum and dura mater. As the bony tissue is not very ſº spongy and vascular, the amount of cal- º \ lus is small; hence openings left by re- ſ | º moval of fragments or after trephining ſº # º º are usually closed principally by fibrous º § sº tissue.

The º fracture may be a single fissure or a series Repair by fibrous tissue after tre- of fissures traversing the cranium for a phining. great distance, even running across sev- eral sutures. There is in such cases little or no separation or displace- ment of the edges. Separation of the sutures is sometimes caused by head injuries. This condition is practically the same as a fracture. Localized Violence, if sufficient to cause fracture, gives rise, as a rule, to comminu- tion of bone, and very often to displacement. This displacement is gen- erally depression, though occasionally elevation of a fragment may be observed. The depressed portion may be attached to the surrounding bone along a part of its margin, thus having an oblique plane; or it may be driven in so deeply that separation of its entire circumference has 9CCurred. One or more edges may be locked under the solid bone. Very frequently the edges of the fragments are bevelled, because the inner table breaks at a greater distance from the point of impact than the outer. This is a frequent cause of interlocking, and of consequent difficulty in elevating the depressed piece. A few cases of fracture of the inner table Without fracture of the outer have been recorded. The diagnosis of §ch gases during life must be obscure, unless the symptoms of brain isturbance are sufficiently localized to justify trephining. Fractures of the ºuter table without breaking the inner may be produced where the bone is thick by any force only sufficient to drive the fragment |: § § º \ 358 I) I S E A S E S A N ID IN J U R I ES OF B O N E S. into the soft diploic structure between the two tables. In children per- manent depression of the bone may occur after injury without actual fracture. This is identical with what has been described as bending of bones and as green-slick fracture. It is probable that some osseous fibres at least are torn. Such a condition in the adult is unknown. SYMPTOMS.–Fractures of the cranium, whether of the vault or base, show no special rational symptoms that may not arise from cerebral con- tusion, laceration, or hemorrhage without fracture. Marked depression of the fragments, however, can be perceived through an untorn scalp by palpation, as can the area of a greatly comminuted fracture which feels soft and is easily depressed by the finger and perhaps shows crepitus. Local subcutaneous emphysema in the mastoid region is diagnostic of fracture into the mastoid cells. A translucent, pulsatile swelling of the scalp is indicative of escape of cerebro-spinal fluid from the ventricles or subarachnoid space, and is conclusive evidence of solution of continuity in the cranial wall. It is, however, a rare phenomenon. Laceration of arteries may give rise to large fluctuating tumors under the scalp without any bone injury; but these are not translucent, nor as a rule pulsatile. Depressed fracture is often stimulated by the swollen and infiltrated tis- sues forming a hard ridge alongside of a softened and less elevated area of scalp. To the surgeon’s finger this condition at times feels identical with a ledge of bone at the side of a depressed fragment. It must also be recollected that congenital depressions and irregularities from old inju- ries, periostitis, and senile changes may exist. When a wound is present the diagnosis is easy, for the fissure in the bone is easily recognized by a red line due to the blood staining the crack. This must not be confounded with the serrated lines shown by the great sutures, and the sutures around occasional Wormian bones. If the outer table is broken the inner one seldom escapes similar lesion. Brain tissue, cerebro-spinal fluid, and blood escaping from the interior of the skull may aid in establishing a diagnosis of fracture. Quite profuse venous bleeding, increasing in vol- ume during expiration, does not prove that a meningeal vessel or sinus has been torn, for it may come from the vascular diploic bone tissue. Fractures of the base of the cranium can rarely be seen or felt by the surgeon’s finger. There may be no special sign of the injury. At times, however, the escape of brain substance, blood, or fluid from the ear, nose, mouth or orbit, or the occurrence of paralysis of some of the cranial nerves may serve to confirm the diagnosis. Bleeding from the ear, nose, or mouth to be of diagnostic value must be profuse and continuous; since limited bleeding occurs from damage to the soft parts in these regions. The appearance of blood at the external orifices of the head after laceration of an intracranial sinus, artery, or vein, is due to fracture of the bony walls of these cavities and rupture of the mucous membrane. In escape of blood from the ear the drum mem- brane is also ruptured. Sometimes, when the petrous portion of the tem: poral bone is broken, and the drum membrane not injured, the blood passes into the pharynx by way of the Eustachian tube, to escape by the mouth or nose, or to be swallowed and subsequently vomited. Marked extravasation of blood under the conjunctiva covering the eyeball, espe- cially if it occur a day or more after the head injury, and it does not appear in the eyelids till some hours later, is very suggestive of fracture of the orbital plate of the frontal or sphenoid bone. Direct external injury to the eyeball and violent vomiting or coughing may also give rise to subconjunctival ecchymosis. So, also, may fracture F R A CT U R ES OF T H E C R A N I U. M. 359 of the malar or upper maxillary bone. Signs of orbital aneurism, such as protrusion of the eyeball, pulsation, and murmur, suggest the occur- rence of damage to the internal carotid artery or the cavernous sinus and make fracture of the cranial base probable. The late occurrence, after injury, of ecchymotic spots in the suboccipital region or below the mastoid process tends to confirm the diagnosis of basal fracture. Discharge from the ear of an abundant, colorless, watery fluid, with little accompanying hemorrhage, especially if it occurs promptly after receipt of injury, and if the flow is modified by the position of the head and by coughing, is characteristic of fracture of the petrous bone and laceration of the tympanic membrane. It is cerebro-spinal fluid which will be found highly saline and almost destitute of albumin. The escape of watery liquid from the ear under other circumstances is of limited diagnostic value. It may be the liquid of Cotunnius from the internal ear, or blood serum escaping from a clot in the oral passages. Cerebro-spinal fluid, in rare instances, may escape from the nose or mouth because of fracture of the spheno-ethmoidal portion of the base, or petrous fracture without rupture of the tympanic membrane. In the latter event the intact membrane prevents escape from the auditory meatus and the fluid passes into the pharynx by the Eustachian tube. Escape of cerebro-spinal fluid or abundant hemorrhage in basal fractures is an evidence of serious, but not necessarily fatal injury. Paralysis of a cranial nerve occurring immediately after the receipt of a head injury may be due to laceration of the brain near the origin of the nerve or to hemorrhage within the nerve sheath. It is very suggestive, however, of fracture of the base with synchronous rupture, contusion, or compression of the nerve trunk. The pressure may arise from the ex- istence of displaced bone or a large clot. The nerves most frequently subjected to such conditions in basal fracture are the facial, auditory, optic, and olfactory. TREATMENT.-There has been until recently much discussion regarding the proper treatment of cranial fractures. Some surgeons opposed oper- ative interference in the great majority of cases, while others believed that a more frequent adoption of trephining would give an increased ratio of cures. As death from the associated or induced brain lesion is common in fractures of the cranium, it is certain that the mortality will be de- creased by early and more frequent antiseptic operations. Elevation and removal of bone with extraction of splinters of the inner table, removal of large clots, and incision even of the dura mater would avail nothing in cases where there has been serious contusion or laceration of the interior of the brain substance; but many cases undoubtedly die because peripheral lesions immediately adjacent to the site of fracture are untreated by mechanical means until the pathological process has advanced too far to be remediable. Fractures of the base are amenable to but little operative treatment, except that the nasal cavities and ears should be made aseptic and plugged with gauze impregnated with beta-naphthol, carbolic acid, ºr iodoform. The general treatment is identical with that proper in fractures of the vault, as is the operative treatment when the lesion is accessible. The shock following head injuries is to be met by recumbency and the *easures spoken of in the section discussing Concussion and Contusion of the Brain. Care must be taken not to continue a stimulating line of treatment after reaction has fairly begun, because the danger in these *ses pertains to encephalitis, which is a possible sequence of the injury. 360 D IS E A SES A N ID IN J U R IES OF B O N E S. As soon as the condition of shock will permit, therefore, elevation of the head, cold to the scalp, low diet, perfect quiet, purgatives, and bromide of potassium (3ij to 3iv in twenty-four hours) should be insisted upon. Alcoholic stimulants should not be given unless the primary shock is pro- found, and then should be speedily discontinued. Shaving the entire scalp is a wise measure, since it permits more accurate examination for scalp-wounds and cranial depressions, and, in addition, renders the appli- cation of cold to the head more effective. A rubber bag or bladder filled with cracked ice, a coiled tube with cold water circulating in it, or cloths wet with ice-water, are easy methods of applying cold to the scalp. If ice is used, a degree of cold sufficient to freeze the skin might be obtained in careless hands. Retention of urine often occurs, and requires the use of the catheter. General bloodletting or cupping at the back of the neck may be necessary in the stage of inflammation. These questions, however, as well as the symptoms of traumatic inflammation of the brain, are all discussed under the head of Encephalitis, which should be referred to in this connection. Opinions still differ somewhat as to what circumstances render it justi- fiable to convert, by incision, a closed cranial fracture into an open one, or to perforate the skull by trephine or saw and thus expose the dura mater. I look upon incision of the scalp and trephining as exploratory rather than therapeutic measures. In many instances the uncertainty as to the cranial lesion is more dangerous to the patient’s life or future health than the conversion of a closed into an open fracture or the ex- posure of the encephalon by perforation of its bony wall. Improved methods of wound treatment have greatly lessened the risk from such operative procedures, but encephalitis is as fatal as ever. The symptoms denominated “compression of the brain * are probably the evidences of encephalic inflammation rather than of brain compression. As this in- flammation is frequently due to injury from spicules of the inner table of the bone, to irritation from intracranial bleeding, or to septic infection, I prefer to eliminate by operation the possibility of this inflammation being due to local causes under the seat of fracture. In punctured fractures immediate trephining to remove the depressed and splintered bone, to sterilize the wound, and thus to avert encephalitis, is advised by all authorities. This should be the line of treatment, even when no cerebral symptoms have developed. Punctured fractures are those open fractures with accentuated depression that result from blows inflicted by the corner of a brick, the point of a spike, or any very local- ized force that produces a puncture of the cranial wall with extensive splintering and driving-in of the inner table. Gunshot fractures of the cranium are, in my opinion, to be treated as punctured fractures. The following tabulated statement gives my views concerning the proper treatment of cranial fractures. I admit that it is more heroic than that generally taught, but it has been written only after careful consideration of the reasoning of those who hold the opposite opinion to my own. Every case must be individually studied, and the patient's chances of death, of return to perfect health, and of life with subsequent epilepsy or insanity carefully weighed; but for a working rule to guide the student and practitioner, I think experience will show the indications given in the table to be correct. Trephining, properly performed, is in itself so free of danger that in a doubtful case the patient had better be trephined than allowed to run the risk of death, epilepsy, or insanity.

Trephine. In classes 3 and 11 I should be inclined to trephine if the depression was marked or the fissures sufficiently multiple to approach the character of a comminuted fracture. In classes 5 and 13 I should trephine unless the comminution was found to be inconsiderable. Operation, when decided upon, should be performed at once or certainly not delayed more than a few hours. All cases, whether trephined or not, should be treated as cases of incipient encephalitis. When careful study of the paralytic and other symptoms accompany- ing head injuries localizes the cerebral lesion near the seat of contusion of the scalp, incision is to be resorted to promptly, even if there is only a suspected fracture. If no fracture is found trephining should, as a rule, be performed, because it is probable that a hemorrhage has occurred either between the bone and dura mater or under the dura mater. Trephining Will permit the surgeon to remove this source of trouble if outside the dura mater; if absence of pulsation or change in color of the dura mater is observed he should incise that membrane in the expectation of finding a clot beneath it. The study of cerebral localization should be cultivated by all surgeons, for many cases of head injury would be treated much more successfully than is usually the case if the neurologist and surgeon employed their skill in combination. The symptoms and cranial lines by which neurolo- gists locate brain lesions have been referred to in the section on Encephal- itis, which should be read in this connection. Incision of the dura mater, *Spiration of the brain substance, and the excision of brain tumors will become less unusual when all surgeons are familiar with the principles of Cerebral localization." In fracture of the cranium trephining is sometimes demanded by the paralytic and other symptoms localizing the lesion under the seat of fracture, when the amount of damage seen in the skull Wºuld lead one to abstain from operation. Hence cognizance of the sig- *ificance of local palsies and spasms is demanded of the skilled Surgeon. c º, greative Surgery of the Human Brain, by John B. Roberts. P. Blakiston & 362 D IS E A SES AN ID IN J U RIES OF BO N E S. TREPHINING-Perforation of the cranium should usually be done by means of a slightly conical trephine, which is safer than the cylindrical instrument, except in the hands of one familiar with the operation. Holes of various shapes can readily be made by the flat-face burr of the surgical engine, but this apparatus is not always obtainable. Holes of any shape Flg. 157. sº *ºº & Hopkins's gnawing forceps. and size can be made by enlarging a small trephine cut with the gnawing forceps. Since the usual object in cases of fracture is to get an opening through which to insert an elevator to pry up the depressed fragments, a small trephine should be employed. One not over three-eighths of an inch in outside diameter at the cutting edge is large enough. In opera- #ſſiſi. #: h # º § : - $ii; * º º º º d #.

After the induction of anaesthesia, the incision in the scalp should be made of a horseshoe shape, with its con- vexity downward when the patient is recumbent, so that during the after- treatment the drainage may be free. If a wound previously exists it may be enlarged by a conical incision, though the horseshoe flap affords better F. R A CTU. R. E S OF T H E C R A N I U M . 363 exposure and should be made if the shape and position of the wound will permit. The knife should divide the scalp and periosteum at the same time in order that all the soft structures may be raised in one layer. If any periosteum remains attached at the seat of operation it should be pushed back with the knife handle. In trephining for epilepsy, cerebral abscess or tumor the periosteum need not be removed except at the point where the crown of the trephine is applied. Indeed a circular incision in it the size of the disk to be re- moved is all that is needed. When the aseptic button of bone is to be replaced in the gap the periosteum upon its upper surface may then be utilized for holding sutures passed through it and then through the peri- osteum at the margin of the opening. The crown of the trephine should be placed on the bone perpendicu- larly to its surface, but before its application the centre-pin of the trephine must be protruded about one-sixteenth of an inch. In fractures the in- strument must be placed on solid and undepressed bone with about one- third of the crown overlapping the portion to be elevated. If the latter precaution is not observed, a bridge of solid bone will be left, which will prevent the application of the elevating lever. Elevation and extraction are often facilitated by removing a disk at the least depressed edge of the depressed fragment. The trephine should be semi-rotated from left to right and right to left, with moderate pressure against the bone. As soon as the groove is made sufficiently deep to maintain the cutting edge in position, the centre-pin is retracted lest it should perforate the inner table and membranes. The trephine is then reapplied and the groove cau- tiously deepened. When blood begins to flow it is evident that the diploic structure is being cut by the sawing edge, and additional care must be exercised, since the inner table is thin. In some skulls, however, the diploé is practically absent. After , , , a few more half-turns have been : made the trephine is removed, and $ the depth of the groove ascertained §: by carrying along it the point of a º probe or pin. If the skull is of un- ; even thickness, as shown by the cran- ial wall being completely divided in One segment of the circle and not in the remainder, the trephine must be tilted toward the uncut side and cau- tiously rotated, or a segment trephine may be used. Very soon the disk is found to be loose, and is readily picked or tilted out by forceps or # elevator. . If the Roberts's aseptic wº trephine is employed there is less Author's segment trephine. danger of Sepsis because there is no °ntre-pin tube to retain bacteria. The disk is then dropped out of the *ºn instead of retracting the pin when a groove is cut. he point of an elevator is then pushed under the depressed fragment, and used as a lever to raise the bone into place, Loose pieces and spicules -SS - sº -: sº * ñº), h * + ; : † : ; ; IE º | -- - º, Il Wººl *††† Nºt # # l 2 t º W t N b{j %\\ w > sº * - -** - 5 : 364 DIS E A SES AN ID IN J U R I ES OF B O N E S. of bone are removed by the elevator or forceps; but care must be observed not to twist during extraction a large and interlocked fragment so as to lacerate the dura mater. It is better to saw away the ledge or point of bone interfering, or even to make a second trephine hole. There is usually in comminuted fractures one piece that acts as a keystone; when this is removed or elevated, the other fragments are readily managed. The Hey’s saw and gnawing forceps do good service in cutting away corners of bone. Spicules driven into the membranes or brain should be searched for with the finger, and at once removed. Finally, all sharp edges of bone should be trimmed away, the wound washed with sublimate solution, a drain of catgut or rubber tube inserted, the scalp flaps sutured in position, and the gauze dressing applied. No metallic plate is ever used after trephining. The bone wound closes usually by fibrous tissue, the Scalp wound heals as do other wounds of the soft parts. It is common now to replace all or some of the fragments of bone, in order that they may aid in closing the gap in the skull, by furnishing Osseous tissue and in- ducing Ossific deposition in the granulation tissue. To accomplish this successfully, it is necessary that the fragments taken out be thoroughly cleaned in an antiseptic solution, of a temperature of about 105° F., and then kept warm in a similar antiseptic lotion, or between warm antiseptic cloths, until the moment before the flaps are to be sutured. The bony fragments are then laid loosely upon the dura mater and covered by the scalp tissues. This procedure is most successful in exploratory operations, because then there is less probability of the grafts being septic. Incision of the dura mater, hypodermic puncture of the brain, or even incision of abscess in the brain, does not alter the method of procedure, So far as the preliminary trephining and after-dressing are concerned. The dura should, however, be sutured with catgut if large incisions have been made in it. The bone grafts can then be laid upon it; but provi- sion should be made for removal of serous exudations and blood by drainage. The drainage tube or threads may be removed in thirty-six hours, if the wound is aseptic. If it is possible to avoid doing so, the trephine should never be applied over the Superior-longitudinal sinus, the lateral sinus, the torcular Herophili, or the middle meningeal artery where it grooves the anterior- inferior angle of the parietal bone. Hemorrhage from wounding these structures may prove very serious. The removal of comminuted bone, however, may lay open these vessels. Bleeding from the artery may be arrested by ligation, by forcing a piece of wood into the bony canal, if there is one, or by seizing the vessel and the bone in a pair of spring forceps, which can be left in position for several hours. Hemorrhage from the venous sinuses may at times be controlled by forcing a little pad of absorbent gauze or sponge between the vessel and the overlying solid bone. Ligatures or a suture carried around the bleeding vessel by means of a needle should be tried when the hemorrhage persists. Trephining over the sinus, at a point a little distance from the wound, might be required to enable the surgeon to apply such a suture; but this event must be exceedingly rare. Hemostatic forceps may be left in situ until the first dressing is changed. In trephining over the air-cells in the frontal bone, called the frontal sinuses, a large trephine should be used to perforate the outer table, and a smaller one to bore through the inner. FRACTU RE OF T H E N A SAL BONES AND C A RTIL AGES. 365 Fractures of the Bones of the Face. Fractures of the facial bones are usually the result of great direct violence; hence several of the bony components of the face may be broken by the same injury. Owing to the great vascularity of the parts, union takes place quickly and with the formation of but little callus. It is im- proper to remove splinters of bone which seem to have but slight attach- ment, for necrosis of such pieces is uncommon. Fracture of the Nasal Bones and Cartilages. Injuries of the nose producing fracture may involve, in addition to the nasal bones, the nasal processes of the Superior maxilla, the frontal spine, and the perpendicular plate of the ethmoid upon which the nasal bones are supported. The cartilaginous septum is often bent or broken, and the lateral cartilages may sustain similar lesions, or be torn loose from the lower end of the nasal bones. The womer likewise may be broken. It is said that fracture of the cribiform plate of the ethmoid may accom- pany fracture of the nasal bones. I can scarcely conceive of this occur- ring, unless the force was violent enough to cause fracture first of the frontal bone. Such instances are properly considered and treated as fractures of the cranium. In young children the arch made by the junc- tion of the two nasal bones, may, it is said, be flattened from the suture opening on the posterior aspect. Blows received directly on the top of the nasal bridge would have this tendency. Fractures of the nose are often comminuted, and attended with much swelling. The swelling, which rapidly appears, is liable to conceal the displacement, interfere with accurate diagnosis, and obstruct nasal respiration. Congenital deviations of the septum may deceive the surgeon. Emphysema of the face may occur from air escaping into the subcutaneous cellular tissue during efforts at blowing the nose soon after the injury. This symptom needs no treatment. Some suppuration often occurs, because the mucous membrane is torn and bacteria get access to the wound from the nasal chambers. Caries and necrosis are rather un- usual, but may occur. Union generally takes place rapidly, and is com- plete within two or three weeks. If the fracture extends into the nasal processes of the superior FIG. I 60. maxilla, the lachrymal duct may become occluded by the displacement or by callus. The risk of permanent disfigurement is so great and union occurs so soon that careful examination and replacement should be instituted promptly, and, if necessary, under an anaesthetic. If the nasal bones are depressed, a narrow and rigid in- Strument, such as a grooved director, passed into the nostril will probably enable the surgeon to ele- * Vate the fragment. When there is a tendency for Author's method of pin- the depression to recur, a steel pin or needle may ning nasal septum. be thrust through the nose from right to left under- neath the broken bone. A strip of rubber or adhesive plaster carried across the dorsum of the nose is then attached to the ends of the needle. Perforated shot may be clamped upon the ends of the pim to prevent 366 DISE As ES AND IN J U RIES OF BONES. spreading and flattening of the nasal bridge. It is well to place a small disk of rubber on the pin, between the skin and the shot, to prevent ulcera- tion and to maintain elastic compression. The pin should remain in position for about ten days. When a tendency to displacement of the cartilaginous portion of the nose is present, the proper conformation should be main- tained by transfixing the cartilages with pins, and, by a sort of leverage action, pinning them in place. I have found this method effectual, after incising the deformed cartilage in cases of nasal deformity from fractures received many years previous to operation." Plugs and canulas in the nostrils are uncomfortable, unnecessary, and inefficient... Cooling lotions may be applied to the fractured nose, if there are much pain and swelling. Patients should be cautioned against violently blowing the nose or snuffling, for displacement may thus be caused. If profuse hemorrhage occurs, the nostril on the bleeding side should be plugged. The method recommended by Dr. R. J. Levis is the simplest and best. To the end of a strong string, about eight inches long, a disk of moistened sponge, about three-fourths of an inch in diameter and three- eighths of an inch in thickness, is firmly tied. This sponge is oiled, and, by forceps, pushed into the nostril and along its floor till it reaches the posterior nares. Upon the string hanging from the anterior nostril four or five similar disks of sponge are strung by central holes like beads, and consecutively crowded into the nose until the cavity is filled. After the lapse of twenty-four hours the disks are removed one by one. This method is much better than that accomplished by means of Bellocq's canula, and is applicable to idiopathic as well as traumatic bleeding. Fracture of the Malar Bone and Zygoma. These rare injuries are readily recognized by the deformity and the irregular outline, which can be felt by the fingers. If fracture of the malar bone extends into the floor of the orbit, the superior maxillary nerve may be injured, subconjunctival ecchymosis appear, or protrusion of the eyeball from intra-orbital hemorrhage take place. In fracture of the zygomatic arch the mouth may not open freely, because the displaced fragments obstruct the movement of the coronoid process of the lower jaw. Pain and swelling sometimes simulate or increase this disability. The treatment consists in replacement by pressure of the fingers upon the cheek or within the mouth. If necessary, an incision may be made for the introduction of a lever under the displaced bone, or a screw may be fastened into the bony surface and used to pull the fragment upward. Fractures of the Superior Maxillary Bone. The alveolar, nasal, and other processes of the upper jaw bone are the parts that most frequently sustain fracture. Even these injuries are uncommon, except fracture of the alveolar process during the extraction of teeth. The lachrymal canal, the orbit, and the superior maxillary nerve may be involved in the injury, with results similar to those de- scribed above under nasal and malar fractures. Union occurs in three or four weeks. Separation of the suture between the two superior max- illaries has been observed. 1 See Cure of Crooked and Otherwise Deformed Noses, by John B. Roberts, Phila., 1889. FRACTURE OF THE IN FERIOR MAXI LLA R Y BON E. 367 Examination of the surface of the face and of the interior of the mouth will disclose the nature of the lesion. In treating such fractures loose teeth should be left in place, for they frequently become firmly fixed again. Apposition can sometimes be maintained by keeping the teeth of the lower jaw firmly closed against those of the upper by means of Bar- ton's bandage or a band of adhesive plas- ter passed under the chim with its ends FIG. I. 61. crossed at the top of the forehead. Wiring the teeth adjoining the line of fracture is sometimes a good means of preventing motion. The inter-dental splint, which is a mould of gutta percha or similar plastic material made to fit the grinding surfaces of the teeth of both jaws, will in most instances act sufficiently. It is placed in position, and the mouth kept shut by bandaging or adhesive plaster. Cork cut to fit the teeth in the same manner will answer a good Gunning's inter-dental splint, with purpose if no dentist is at hand to make opening for introducing food. the more complicated apparatus. During the three weeks that closure of the mouth is enforced, liquid food is introduced through the crevices between the teeth or by a tube passed between the alveolar arch and cheek as far back as the last molar. Inter- dental splints may be made thick enough to have a perforation for this purpose. Fracture of the Inferior Maxillary Bone. The lower jaw is more frequently broken than any other bone of the face. The seat of fracture is generally toward the anterior part of the body of the bone. Fracture of the ramus is comparatively rare, and fracture of the condyle and coronoid process even more unusual. The body of the bone is said to be weaker and more easily broken near the root of the canine tooth and the mental foramen than elsewhere. Loss of teeth and consequent atrophy of the alveolar process may reduce the normal strength of the FIG. 162. bone in other situations, and be the predisposing cause of fracture. The most frequent seat of fracture, according to Gurlt's statistics, is near the middle line in front. These statements exclude from consideration mere splintering of the alveolar process often produced by pulling teeth and by other causes. Double fracture of the lower jaw is not uncommon. When the body of the bone is broken the fracture often communicates with the mouth through a tear of the gum. The fracture be- gomes in such cases, therefore, an open one, and º is accompanied by suppuration because it can- Fracture of lower jaw behind not be kept aseptic. Suppuration is usually teeth. not Very great, for drainage is free. The close attachment of the fibrous tissue of the gum to the alveolus is a sufficient explanation of this frequent complication. The inferior dental nerve 368 DISE A SES AND IN J U RIES OF BONES. may be torn or bruised when its canal is involved in the fracture. An- aesthesia of the corresponding half of the lower lip and chin is the result of this nerve lesion. The displacement and unnatural mobility in fracture of the body are easily detected, but the surgeon must bear in mind the possibility of mal- positions of the teeth from irregular development and irruption. In single fracture of the body away from the median line the anterior fragment is apt to be displaced inward toward the mouth. In double or bilateral fracture of the body the middle or chin portion may be drawn downward by muscular action. The displacement in fracture of the ramus is more difficult of detection, but may often be recognized with the finger in the mouth. Pain, often increased by motion or deglutition, and excessive secretion from the mouth are observed in fracture of the lower jaw. Perhaps the increase of saliva and mucus is largely apparent, the excess observed being really due to a want of proper control of these fluids within the mouth. Fetor from decomposing food, pus, and other secretions is often marked. Abscesses about necrosed pieces of bone, fistulous tracts, and ulceration of the mucous membrane may add to the discomfort of the patient, who perhaps becomes greatly debilitated by swallowing foul secre- tions and being deprived of a fully nutritious diet. |Union of ordinary fracture of the jaw takes place in five or six weeks. The prognosis, even in bad cases, is ultimately good. Even if teeth are lost the solid union which occurs gives a good basis for the adaptation of artificial teeth. FIG. 163. FIG.

Reduction of the fracture by pressure of the fingers on the teeth is usually easy, though occasionally comminuted fragments or displaced teeth may cause interlocking and require removal before correct apposi: tion is obtainable. Teeth which are simply loosened should not be pulled unless they impede reduction. Tenotomy of displacing muscles is rarely necessary. The liormal relation of the upper and lower teeth in most mouths is that the upper incisors come in front of the lower when the mouth is quietly closed. This should be recollected. Generally there is little tendency to displacement after ten days have passed. Hence after FRACTURE OF THE IN FERIOR MAXILLA R Y BON E. 369 the lapse of about three weeks the dressings may be removed, and the patient given an opportunity to attempt mastication cautiously in order to demonstrate whether the fragments have been adjusted in a manner to give the best use of the teeth in chewing... Any slight change in adjust- ment is then possible, for consolidation will not be complete. After re- duction uncomplicated fractures of the jaw are to be treated by keeping the upper and lower teeth in contact by means of the Barton figure-of- eight bandage of the occiput and chin. The mouth must be cleansed with disinfectant washes of carbolic acid or beta-naphthol, tincture of myrrh (m_xv to fij of water) and similar drugs. Feeding, as in fracture of the upper jaw, is accomplished by introducing milk and soups through the crevices between the teeth, or by a tube passed behind the last molar or through the nostril. The hair and beard of men should be closely cut before these bandages are applied; otherwise they are apt to slip or be very uncomfortable. * When the simple bandage does not give sufficient firmness to cause maintenance of correct apposition, or when the lateral pressure of the bandage causes overriding, it is well to adapt a moulded splint to the out- side of the chin. Pasteboard, felt, leather, gutta percha, or gauze stiffened with gypsum are the proper materials from which to construct a hollow cap to fit the front and lower surface of the chin. The splint should ex- tend on each side nearly as far back as the angle of the jaw; and may need a crescentic portion of its posterior edge cut away in order to avoid pressure on the throat above the larynx. The splint is padded and placed Over the chin and held in position by the bandage. Before applying the bandage, the splint may be fixed in position by carrying a band of rubber adhesive plaster over the splint and as high up on the cheeks as the Zygoma. FIG. 165. FIG. I66. Original shape of gutta percha or pasteboard. Gutta-percha splint moulded to fit chin. If the tendency to displacement is persistent, wiring the fragments together 9r some form of interdental splint becomes necessary. A strong silver or iron wire may be fastened around several teeth on each side of the fracture; or in open fractures the ends of the bone may be drilled and, wire sutures passed through. Interdental splints are splints worn *ide the mouth and so fitted to the teeth and alveolus that motion at the seat of fracture is prevented. An impression of the teeth and alve- olus is taken while the fragments are held in position. By means of this *P*śsion a splint of metal or vulcanized rubber is constructed which *ins indentations into which the teeth accurately fit. If such a splint **pplied to the teeth of the broken jaw and fixed so that the jaw bone ls kept continually in close contact with it motion at the seat of fracture **Possible, because the crowns of the teeth are buried in indentations on the surface of the splint. There are several methods of securing the 24 370 D IS E A S E S A N D IN J U RIES OF B O N E S. splint to the jaw. Probably the best is to have the upper surface of the splint fitted to the upper teeth. The jaws are then closed upon the splint and kept in that position by a Barton bandage. Lateral motion is prevented by the depressions into which the teeth fit. Such an interdental splint can be made thick enough to permit openings for feeding between the upper and lower surfaces of the splint. An illustration of this splint is shown above under Fractures of the Upper Jaw. Instead of using the upper jaw for immobilization the splints may be fitted to the lower jaw alone and attached by rods coming out of the corners of the mouth to a splint under the chin. A simple splint is made by softening a gutta- percha strip in hot water, moulding it to the crowns of the lower teeth so as to overlap the adjacent gum and hardening it by cold water. Such a splint may be fixed in position by wires carried by means of needles through the muscles and skin of the chin and twisted under the chin over small rolls of plaster or pieces of cork. In subjects who have lost all or nearly all their teeth interdental splints moulded to the atrophied gums present about the only efficient means of maintaining immobility. In all forms of splints greater immobility will as a rule be obtained by bandaging the jaws together. If desirable, gutta-percha wedges may be placed between the jaws on each side of the mouth in order to have a space in the middle for introduction of food. A crude form of interdental splint may be made of cork cut to fit the teeth of the two jaws. Fracture of the Hyoid Bone. The hyoid bone is rarely broken, and when sudden lesion is sustained the bone usually gives way near the junction of the great horn and the body of the bone. Fracture of the hyoid bone is at times associated with fracture of the laryngeal cartilages, and is due to similar causes, namely, pressure of the rope in hanging, grasping the throat by the fingers as in homicidal assaults, and direct blows upon the bone. The symptoms of hyoid fracture are sharp pain, increased by pressure, speaking, or swallow- ing; swelling, displacement and motion of the fragments, and crepitus. If the mucous membrane of the pharynx has been perforated blood will appear in the mouth. Sometimes the surgeon's finger in the pharynx will detect the displacement with ease. Coughing with paroxysms of choking or asphyxia may follow attempts at swallowing food or protruding the tongue. The treatment consists in replacing the fragments, keeping the parts quiet by prohibiting talking, and feeding the patient on liquids by means of a tube. Bandaging the throat is of no service. Fracture of the Cartilages of the Laryma. PATHOLOGY..—These injuries, owing to the exposed position of the larynx, are more frequent than fracture of the hyoid bone. They are at the same time more dangerous, because the intralaryngeal swelling is very liable to cause fatal asphyxia. Blows, falls, hanging, and homicidal throttling are the causes likely to produce laryngeal fracture. The mucous membrane is frequently torn, leading to extravasation of blood within the larynx and emphysema of the cellular tissue of the throat and neighboring regions. The upper horn of the thyroid cartilage is someº { F R A C T U R ES OF T H E S T E R N U M. 371 times developed as a sort of epiphysis. Epiphyseal separation may then OCCUll’. SyMPTOMS.–The symptoms are deformity, motion, and crepitation, accompanied by convulsive cough, alteration or loss of voice, dyspnoea, painful deglutition, and in many instances frothy, bloody, expectoration. The emphysema that is seen in many cases may spread over a large por- tion of the neck, face, and trunk. In severe fractures death is common from Suffocation due to subcuta- neous hemorrhage, to free bleeding into the larynx, or to inflammatory or emphysematous swelling. The fatal issue may suddenly occur several days after the receipt of injury. Repair occurs most probably by Osseo-cartilaginous material. TREATMENT.-The treatment consists in remedies to allay inflamma- tion, and cautionary tracheotomy, lest fatal obstructive swelling occur unexpectedly in the larynx. The opening thus made may be of value in giving the surgeon an opportunity to replace the broken fragments by the introduction of instruments into the air-passages. It is unwise to post- pone tracheotomy until dyspnoea becomes extreme, since asphyxia may be sudden. The operation had better be done in all cases of severe frac- ture before the patient is left by the surgeon. A permanent tracheal opening is sometimes demanded after fracture of the larynx. The tracheal rings occasionally sustain fracture. The diagnosis is often difficult, but if such injury is discovered it should be treated as fracture of the larynx by antiphlogistic measures and tracheotomy below the seat of injury. Fractures of the Sternum. PATHOLOGY..—This is a rare injury, probably because the sternum is protected from indirect violence by being connected with the elastic costal cartilages and ribs. When fracture occurs it is usually due to such great violence that associated injury to the ribs or thoracic viscera exists; but a direct blow of moderate force may, if limited to a small area, break the sternum. Violence which forcibly bends the spinal column backward or forward may give rise to Sternal fracture in some cases, as it may cause ver- FIG. I.67 tebral fracture in others. Great muscular efforts, such as occur in lifting heavy weights or in par- ºn, have been followed by disruption of this One. The first portion of the sternum, or manubrium, and the last portion, or ensiform appendix, often become united in adult life to the gladiolus, or cen- tral segment, by Osseous material. In early life, and Sometimes until much later, more or less perfect joints exist at these points. Therefore it is difficult and ºften impossible to say whether a given traumatic displacement is a fracture or a dislocation. Dis- Placement between the first and second segments, the ºsult of direct violence, may be diagnosticated as c. diastasis or dislocation rather than fracture when Fracture of sternum. * Patient is young. The symptoms confirmatory of this diagnosis are the half facets for the second ribs or a smooth upper facet being felt through the skin, the cartilages of the second rib being 372 D IS E A S E S A N D IN J U R I ES OF B O N E S. out of place and easily reduced to position, and no crepitus being dis- coverable. In fracture the periosteum on the back of the bone is more likely to be torn, hence inflammatory involvement of the mediastinal structures becomes more possible, For this reason FIG. 168. the differential diagnosis has some bearing on prog- º Il OSIS. Sternal fractures are generally more or less trans- verse. Congenital fissure may be mistaken for lon- gitudinal fracture, which is a very rare lesion. The frequent irregularities of the ensiform appendix must not be forgotten. Union usually occurs promptly, and little annoyance arises from uncomplicated frac- ture even if some deformity persists. Cases asso- ciated with rupture of the lungs or pericardium, or with profuse bleeding or consecutive suppuration in the mediastinum, are of grave prognosis. SYMPTOMS.–The symptoms of fracture of the sternum are displacement, mobility, crepitus, pain on motion, deep breathing or coughing, bloody expec- toration, dyspnoea, and sometimes a stooping position of the shoulders because of the shortening of the breast bone. Replacement can best be accomplished by traction and pressure. If a hard pillow is placed under the patient's back and his trunk bent back- ward over it, the fragments can often be easily pressed into position. A deep inspiratory effort may assist the reduction. Recurrence of the deformity is not unusual. It has been proposed to screw a Transverse fracture gimlet into the depressed portion of the bone, and of body of sternum. thus pull it upward, or to insert an elevator or hook (STIMson.) under it. These means increase the severity of the injury, but are justified by symptoms arising from pressure on the heart and lungs. Unfortunately the bone is rather too cancellous in structure to give a good firm hold for such instru- ments. Entering the mediastinal space or puncturing the pericardium or pleural cavity is to be deprecated. After reduction, if there is a tendency to displacement or much pain present, the chest should be immobilized by a broad bandage of flannel or adhesive plaster firmly applied, while the lungs are emptied by forced expiration. If intra- thoracic symptoms arise, they should be treated on general principles. Pus behind the sternum should be promptly evacuated by incision along the side of the sternum or by trephining the bone. Stimson has sug- gested removing a disk of bone without disturbing the posterior perios: teum, and then puncturing this with the aspirator needle, which may be passed in various directions until the suspected pus cavity is found or its existence disproved. Antiseptic incision of the posterior layer of the periosteum would seem to be better surgery. A post-sternal abscess may simulate aneurism because of its transmitting the cardiac pulsation, Fractures of the Ribs and Costal Cartilages. PATHOLOGY..—Fractures of the ribs are frequently met with in adults, but quite rarely in children. The greater elasticity of the bones and F R A CT U R ES OF THE RIBS AND COST AL CART ILA G E S. 373 costal cartilages in childhood sufficiently accounts for this difference. The occurrence of green-stick fracture may, perhaps, be often overlooked in chest injuries among children, and even in adults the periosteum at times remains almost intact, and thus obscures the symptoms of fracture. The protected situation of the first and second ribs behind the clavicle, and the mobility of the last two ribs, render fracture of these bones unusual. The ribs most commonly broken are the fourth, fifth, sixth, and seventh. Unless several ribs are simultaneously broken over-riding is impossible, for the adjoining ribs and the intercostal structures act as splints. Angular deformity is in the same way a good deal limited. Comminution, when great, changes the rigid thoracic wall into a flaccid membrane, moving in and out with respiration. Direct violence, by driving the rib inward, causes fracture at the point of impact, and generally with inward displacement. Indirect violence, by depressing the chest, has a tendency to bend the rib and cause frac- ture, beginning on the external surface. Outward displacement is prob- ably the more common deformity in these cases. Erichsen thinks that in indirect fractures the bone usually gives way near its angle, which is the point of greatest convexity. Direct injury, of course, will give rise to fracture in the anterior or posterior region, according as the violence is received upon the one or the other portion of the bone. Direct violence is more apt to cause splintering of the inner surface of the bone and inward displacement; consequently there is, under such causation, more likelihood of puncture of the viscera. Contraction of the extra- thoracic muscles during violent respiratory efforts, as in coughing or sneezing, may cause fracture of a rib. The rather frequent occurrence of broken ribs in connection with general paralysis of the insane is said to be due to trophic changes in the bones making them more brittle. Injury to the thoracic or abdominal contents is not an infrequent asso- ciate of rib fractures. The most common indication of such injury is subcutaneous emphysema about the seat of fracture due to puncture or rupture of the pleura and lung. This is probably more frequent when the rib is broken at the situation of an old inflammatory adhesion of the pulmonary and costal pleura than when no such adhesions exist. When the wounded lung is previously non-adherent the air from the bronchioles and vesicles sometimes escapes into the pleural cavity, giving rise to pneu- mothorax instead of distending the subcutaneous cellular tissue and caus- ing emphysema. The lung may actually become compressed and collapsed by large quantities of air and blood in the pleural sac. When the emphy- sematous condition spreads into the mediastinum and the interlobular cellular tissue of the lung the patient's condition becomes critical. Peri- gardial and heart injuries are infrequent except after very great violence. It is to be recollected that laceration of the viscera may occur without fracture of the ribs. Laceration of an intercostal artery may happen even in fracture of a not very serious kind. If the fracture is open so that such injury and the consequent hemorrhage are detected, efforts should be made to secure the bleeding artery by passing a ligature around it. This can perhaps be done by a curved needle carrying a thread through the tissues in the intercostal groove on the lower margin of the rib, or by drilling the bone and passing a wire through it and around the vessel. The wound may be enlarged so that a small key can be passed in and turned in such a manner as to press on the vessel for a few hours. In some cases the centre of a Square of muslim may be forced into the thorax so as to make a pocket 374 D IS E A SES A N D IN J U R RES OF B O N E S. within the wall. Into this cotton should be pushed so as to make the immer part of the packing larger than the opening. If the corners of the piece of muslin are then pulled forward pressure will be made on the intercostal artery. In closed fractures an incision should be made and similar treatment adopted if the diagnosis of dangerous hemorrhage from a torn intercostal artery is made. SYMPTOMS.–The symptoms of uncomplicated fracture of the ribs may be so obscure that certainty of diagnosis is impossible. Green-stick frag- tures are scarcely recognizable except when a nodule of callus is devel- oped at the seat of pain during recovery. Local pain induced or increased by pressure, motion, full inspiration, or coughing is suggestive of fracture, but may be due to mere contusion of the soft parts. Shallow or catching respiration is a common accompaniment of broken ribs and is due to the pain inflicted by deep inspiratory efforts. Cough is often present and has been attributed to reflex irritation from injury to the intercostal nerve lying in the groove of the bone. Pain or ecchymosis at a distance from the part of the chest upon which the violence was received is indicative of fracture. I have learned from Dr. R. J. Levis a manipulation that has often convinced me of the exist- ence of fracture in obscure cases. If the patient lie upon his back and the surgeon make strong pressure upon the sternum and anterior part of the chest, pain will often be experienced at the point of fracture. This is due to the elasticity of the ribs and cartilages causing motion at the seat of fracture even when it exists at the lateral or dorsal aspect of the chest. If no fracture is present sternal pressure cannot give rise to pain at a distant part of the chest wall. Preternatural motion may be difficult to obtain and recognize, because of the normal mobility and elasticity of the thoracic parietes. Crepitation may be elicited by applying the finger-tips to the ribs on both sides of the suspected fracture and making alternating pressure. Motion also may be thus detected. Sometimes crepitation is more readily detected by laying the palm over the painful spot while the patient coughs or the surgeon makes firm pressure in the neighborhood of the injury with the other hand. Auscultation may detect crepitus when other means fail. Subcutaneous emphysema, which is shown by crackling when pressure is made upon the skin is an unmistakable sign of fractured rib and puncture of the lung. The development of a pleur- itic friction sound or of a local pneumonia a day or two after injury, is very fair evidence of a broken rib. Bloody expectoration, pneumothorax, and serous effusion or hemorrhage into the plural sac are suggestive of fracture and simultaneous injury of the thoracic contents, but they may also occur from violence that does not break the elastic ribs. The prognosis is good in ordinary uncomplicated fractures of the ribs. Union occurs in about four weeks by interosseous and insheathing callus which often leaves an irregularity, even when no displacement existed, because perfect immobilization is impossible. Sometimes when several bones have been broken bridges of callus unite the upper and lower borders. Hernia of the lung may occur if much displacement or commin- ution exists after severe fractures. The cellular emphysema in the great majority of cases is unimportant and soon disappears spontaneously. Great dyspnoea from sudden congestion of the lungs or pneumothorax is an important and at times a fatal symptom. Pleurisy, pneumonia, and pericarditis occurring as complications add greatly to the seriousness of the injury and should always be looked for by percussion and auscultation. FRACTU RES OF THE RIBS AND COST AL C A RTILA GE S. 375 Recovery, however, is not uncommon after severe injury to the lungs and other viscera. Treatment.—Fractures of the ribs should be treated by reduction of displacement and immobilization. At the same time the surgeon should be on the alert to avert or relieve intra-thoracic inflammation.

Pressure upon the ends of the frag- ments or upon the sternum may correct deformity and at the same time relieve the existing pain. Deep inspiration on the part of the patient may be of assistance. Occasionally, when overlapping exists the outer fragment may, by pressure, be sprung under the inner one, and its resili- ency used to lift the latter outward into proper relation. If inward dis- placement were causing important symptoms it would be proper to intro- duce a hook or elevator under the depressed bone and thus bring it into pºsition. In gunshot or other open fractures comminuted and detached pieces may at times be extracted with propriety. Immobilization is to be effected by encircling the chest with a broad bandage so that thoracic breathing is restricted. The ribs are thus kept Quiet and the patient required to breathe by the diaphraghm and abdom- inal muscles. The bandage should be made of a piece of flannel or muslim about eight inches wide and a yard and a half long, it should beapplied and firmly fastened with pins during full expiration in order to be sufficiently tight. If the patient is ordered to raise his arms over his head and to 376 DIS E A SES A N D IN J U R IES OF B O N E S. breathe out as much as possible, the girth-like bandage can be firmly adjusted. The gypsum dressing may be thus employed. If the patient has pain from the circular constriction it may be made looser or entirely dispensed with, since in order to avert pain the muscles will immobilize the parts pretty well without external assistance. The bandage must never be carried much below the ensiform cartilage, lest it interfere with the play of the abdominal respiratory muscles. It may be prevented from slipping downward by bands carried over the shoulder. The arm of the adducted side should be bound to the chest or carried in a sling if the motion of the pectoral muscles gives pain. If, in comminuted fractures, displacement inward is caused by the bandage it must be removed. A laced jacket of stout linen, such as has been used in the Pennsylvania Hospital, is an efficient dressing for broken ribs. The dressing may be discarded in about four weeks. A broad sheet of rubber adhesive plaster or several overlapping strips of plaster may be used instead of the bandage. Before applying adhesive plaster all hair on the chest should be removed with the razor. In some cases constriction of the entire chest is very uncomfortable; this is especially so when the patient has asthma or chronic bronchitis. The adhesive plaster is then a preferable dressing, for it is easy to apply it to the injured side only, with the ends merely crossing the median line in front and behind. FIG. 171. FIG. I'72. § S s N § % ag: % Bandage for fracture of ribs. Morton’s jacket for fracture of the ribs. The intra-thoracic inflammations require treatment similar to that indicated in similar lesions from non-traumatic causes. The cellular em- physema accompanying many fractures needs no special treatment, as the air is soon absorbed. The pressure of the bandage perhaps aids in its disappearance. Even when great extension of the emphysema occurs no danger is to be apprehended except when it gets into the mediastinum and interlobular tissue of the lungs. In such an event incisions in the skin or other operative interference could scarcely avail. Extreme Con- gestion of the lungs, giving rise to grave dyspnoea, should be treated by venesection. Pneumothorax, hemorrhage into the plural sac, or large pleuritic effusion may demand aspiration or incision. F R A C T U R ES OF T H E PEL WI C B O N E S. 377 Fractures of the Costal Cartilages. These injuries are said to happen most frequently near the junction of the cartilage and rib, and to occur in the seventh and eighth cartilages oftener than elsewhere. The partially ossified cartilages of the old are more susceptible of fracture than the cartilages of youth. Chondral fractures are usually transverse or nearly so, and are seldom complicated. Deformity is the most constant diagnostic symptom, though at times crep- itus and mobility may be distinguishable. When it is impossible to deter- mine whether fracture or dislocation of the cartilage has taken place the termination of the rib may be made out by acupuncture, for the needle will enter the substance of the cartilage. Union is accomplished not by cartilage, but by Osseous or fibro-Osseous tissue in much the same manner as in fracture of the ribs. The perichondrium seems to furnish the ensheathing callus. The treatment is the same as that for fractured ribs, Fractures of the Pelvic Bones. PATHOLOGY..—Fractures of the pelvis are rare, and require for their production a great degree of violence, except in instances where mere projecting processes are split or torn off. Falling embankments, railroad accidents, and the passage of loaded vehicles across the trunk are the kind of injuries liable to produce fractures of the pelvis. The fracture lines are apt to be multiple, because the crushing force which breaks the pelvic FIG.

Separation of the pubic and sacro-iliac synchondroses or joints is not an unusual result of *matism, and in young persons the epiphyseal lines of the innominate bone may be forced asunder by violence that in older persons would cause 378 DISE A SES A N D IN J U R IB S OF B O N E S. fracture. The pubic, iliac, and ischiatic elements unite between the years of fifteen and twenty; the secondary centres at about twenty-five years. The usual severity of the causative violence and the relation of the pelvis to the viscera render the prognosis as to life unfavorable. Lacera- tion of the urethra, usually in its membranous portion, rupture of the bladder, rectum, colon, or small intestines; injury to the uterus; rupture of the iliac artery or vein; and contusion or laceration of the Solid viscera are not at all infrequent complications. Death from secondary affections, such as suppuration in the cellular tissue of the pelvis or necrosis, must be recollected as a possibility. If no such complications occur, cure of even severe fractures takes place. Union may be expected in from six to eight weeks, but lameness is usual from more or less permanent disability of the muscles injured by the accident, or restricted in their function by the process of union or cicatrization. Deformities narrowing the pelvic canal may occasion serious difficulty in subsequent parturition. The character of fracture varies with the direction of application of the fracturing force. Sometimes the fracture lines are vertical, one or more passing through the rami of the pubes and ischium on one or both sides of the middle line and another through the iliac portion of the innominate bone into the sacro-sciatic notch. In the posterior segment of the circle the sacrum may be split vertically, or the sacro-iliac joint torn open. Lateral crushing may drive the head of the femur through the acetabulum into the pelvic cavity; or, if less severe, may produce lines of fracture radiating from the acetabular region. Parturition, forced abduction of the thighs, and direct external violence have produced separation of the symphysis of the pubes. The separation is said to occur between one of FIG. I 74.

(Bryant.) the pubic bones and its attached cartilage rather than between the two cartilages which the joint contains. The gap felt through the integument may be as much as two inches wide. Occasionally the symphysis of the ubes and one of the sacro-iliac articulations have been torn open so that half of the pelvis and the corresponding leg have been markedly displaced upward. º: the fractures which involve the continuity of the pelvic ring, that in the pubic region is most common, for here the bony constituents of the pelvis are most fragile. F. R A C T U R E S OF TEI E P E L VI C B O N E S. 379 Transverse or nearly transverse fractures of the sacrum or of the coccyx are occasional lesions. In both the tendency is for the lower fragment to be bent inward with its lower extremity pointing toward the interior of the pelvis. , Dislocation of the coccygeal articulations is practically identical with fracture of the ankylosed bone. SYMPTOMS.—Displacement is not very great in the majority of pelvic fractures; but palpation will, if the parts are accessible, usually show either deformity, mobility, or crepitus. Vaginal and rectal exploration will be servicable in a few cases. Shortening of the lower extremity from upward displacement of the pelvis, and inability or indisposition to move the limb will at times aid in the diagnosis. Loss of support, fear of pain, and laceration of the muscles attached to the pelvis may all have part in the production of this disability. A good deal of subcutaneous extrava- sation of blood is frequently a feature of these injuries. Careful observation of the relative position of the anterior spinous processes of the ilium will at times serve to strengthen or weaken an obscure diagnosis. Crepitus may be elicited and correction of deformity secured by traction on the lower limb. Escape of blood from the urinary meatus or rectum, retention of urine, bloody urine, and the rapid super- vention of tympanites or peritonitis suggest the probability of fracture of the pelvis in cases with appropriate history. In sacral fracture, paralysis of rectum, bladder, and legs, from compli- cating lesion of the sacral nerves, is said to be not unusual ; and pain on coughing or defecation may be expected. Seizing the bone between a finger in the rectum and the thumb on the dorsum will probably demon- strate motion and crepitus, and perhaps correct displacement. Coccygeal fracture occurs probably more frequently from parturient efforts and manipulations than from other traumatism. Rectal examina- tion will often establish the correct diagnosis and reduce the displaced fragments. Fractures of the crest or processes of the ilium are probably the least important of the fractures of the pelvic bones, for they have as a rule no serious complications, and confine the patient to bed for only a couple of Weeks or perhaps not at all. Mere fissure of the cavity of the acetabulum has no characteristic Symptom. Fracture of the rim of the acetabulum is worthy of consideration. It usually occurs as the result of great violence applied to the hip, and as an accompaniment of dislocation of the femur. Dislocation backward of the head, with breaking of the posterior and upper margin of the ace- tabular rim, is the ordinary form of the lesion. The symptoms are those of dislocation of the head of the thigh-bone with crepitus, and a ready recurrence of the dislocation after its reduction. Fracture of the neck of the femur may be mistaken for dislocation and fracture of the acetabular margin, because crepitus and recurrence of deformity are essentially marked symptoms in the former injury. In fracture, however, unless it is impacted, the limb assumes a position of outward rotation and §tension, while in the posterior dislocations, which are the varieties likely to be seen here, the limb takes the position of inward rotation and flexion on the pelvis. Again, in fracture the trochanter is relatively *rē, the anterior superior spine of the ilium than in dislocation. It * Well in all cases of doubt to make sure of the actual position of the head, and also to remember that dislocation of the femoral head compli- *ed with fracture of the neck of the bone is not impossible, and that 380 D IS E A S E S A N 1) IN J U R I ES OF B O N E S. the crepitus attributed to fracture of the acetabulum may exist really between the fragments of the broken femoral neck. TREATMENT.—The treatment of fractures of the pelvic bones varies with the location of the injury; but in all the severer forms of fracture the surgeon should at once introduce a catheter, in order that laceration of the urethra may be discovered, if it exist, before extensive extravasa- tion of urine has occurred. Shock must also be treated. If the end of the catheter will not pass beyond the torn portion of the urethra into the bladder, a perineal incision should immediately be made. This incision should be made in the middle line and should open the tissues down to the seat of rupture, to which the end of the catheter left in place is a guide. Exit is thus given for the urine to pass from the opening in the urethra to the exterior, and disastrous extravasation into the perineal structures is averted. It is not proper to open the neck of the bladder unless the bladder itself is ruptured. The incision down to and into the urethra at the point of its rupture is all that is required to conduct the urine to the surface. The case should then be managed, so far as this feature is concerned, as one of external urethrotomy for stricture, by the occasional passage of a bougie. If a catheter can be introduced through the torn urethra into the bladder no incision is demanded, and the instru- ment, preferably a rubber one, should be retained in the bladder for a few days until danger of urinary infiltration has passed. Violent manipulation may increase visceral damage in pelvic fractures and should be avoided, though careful efforts at correcting marked dis- placements are proper. Rest in bed in the dorsal, prone, or lateral posi- tion, according to the comfort of the patient, and support to the pelvis by encircling bands of adhesive plaster or by a broad girdle of muslin or flannel will usually meet the indications. All pressure liable to cause displacement or pain must be avoided by pads. A gypsum dressing may sometimes be serviceable. Continuous traction by weights attached to the leg and thigh as in fracture of the femur, may be the only means of preventing upward displacement in double vertical fractures on the same side of the median line. Fractures of the ischium may require pressure to be applied within the rectum in order to effect coaptation of fragments. The finger or a wooden lever may be employed. A few cases have been treated efficiently by means of packing kept in the rectum for a series of days to prevent recurrence of displacement. The packing, which should be enclosed in a rubber bag, must be occasionally removed to allow defe- cation and escape of flatus, unless a canula be placed through the centre of the distending apparatus. A rubber bag distended with air or water and well oiled, when inserted, would seem to be the most judicious means for effecting this seldom required intra-rectal pressure. In fractures of the iliac wings the encircling bandage must be omitted if it tends to press the fragments abnormally inward. In fracture of the tuberosity of the ischium the hamstring muscles should be relaxed by flexing the leg on the thigh, while the thigh should be extended or semi-extended at the hip. In instances of great comminution, followed by extensive suppura- tion, provision for free drainage should be made, and detached splinters of bone removed early. The neuralgic affection, coccygodynia, whose symptoms are not unlike fissure of the anus, may be a secondary result of fracture of the coccyx. If subcutaneous division of the soft structure attached to the coccyx fails to relieve the pain, removal of the bone by means of the cutting forceps or saw, or with the burr of the surgical engine, may be performed. F R A C T U R E O F T H E C L A VIC I, E. 381 Fracture of the Clavicle. PATHOLOGY..—Direct violence and muscular strain, as in lifting heavy weights, may cause fracture of the clavicle. By far the most common cause, however, is indirect violence, for in falls upon the shoulder, elbow, or hand the force of impact is transmitted to the clavicle, which consti- tutes the only bony connection of the arm with the trunk. A tendency to exaggerate the curves of this doubly curved and doubly twisted bone is thus produced and the bone gives way as soon as the strain becomes too reat. The mechanism of some cases of fracture is, it is said, a forcible bending of the clavicle across the first rib, with which it normally is often almost in contact. With the exception of the radius the clavicle is the most frequently broken bone of the skeleton. The outer part of the middle third is the most common site of fracture, but from its obliquity the line may extend into the outer or inner third. The small diameter of the bone and the sharpness of the curve at this point, associated with the frequent causation from indirect violence, are satisfactory reasons for the lesion showing this preference. Comminuted, multiple, or open fractures of the clavicle are rare. Green-stick fractures are common; and transverse breaks with little dis- placement or laceration of periosteum by no means unusual. Emphysema from puncture of the apex of the lung, paralysis from laceration or con- tusion of the nerve trunks, and lesions of the subclavian vessels are pos- sible but almost unknown complications.

(HAMILTON.) §YMPTOMs. The usual deformity after the ordinary fracture of the middle portion of the clavicle is produced by tilting upward of the outer end of the sternal fragment, and displacement inward, forward, and down- Wºrd of the inner end of the acromial fragment. The projection upward of the former has been attributed to the lifting force exerted by the outer fragment being thrust under it, and also to contraction of the sterno- cleido-mastoid muscle. The displacement inward, forward, and downward 382 DISE A SES AN ID IN J U R IES OF B O N E S. of the acromial fragment is due to the fact that the clavicle is the support or stay which holds the scapula and its attached arm in proper relation to the thorax. When the clavicle is broken, the scapula, partly by reason of the weight of the arm and partly by the action of the great, serrated and the lesser pectoral muscles, assisted, perhaps by the rhomboids, is ro- tated forward around the dorso-lateral aspect of the chest in such a way as to depress the acromion and carry it toward the anterior middle line of the trunk. This displacement of the point of the shoulder and the consequent relation of the clavicular fragments are well shown in the diagram adapted from Stimson. It represents in a schematic way the intact as well as the broken shoulder- FIG. 178. girdle as the claviculo-Scapular combina- \; ERT EBRA tion has been called. The inward and forward displacement of the acromion is seen at a glance. The downward deform- ity, being in another plane, is of course not exhibited. Shortening of the clavicle is great in oblique fractures with over- riding, and may amount to one and a half or two inches. Sometimes, in transverse fractures, interlocking of fragments gives upward and backward angular deformity. In all fractures the continuance of the Diagram showing sliding forward fracturing force after rupture of bone of scapula and tilting out of its pos- has occurred, and the line of break have terior border in fracture of clavicle, influence in determining the amount and direction of the displacement. Fractures of the outer third of the clavicle are often transverse, and, in reference to frequency, come next to fractures of the middle third. The displacement is believed by some writers to be greater as the line of sepa- ration approaches the acromion and gets outside of the attachment of the coraco-clavicular ligament. This, however, is denied by the high au- thority of Gurlt and Gordon. The deformity is usually angular, with the acromial fragment thrown forward. In fractures of the inner third the most usual deformity is due to dis- placement downward and forward of the inner end of the acromial por- tion of the bone, or angular distortion of both fragments in the same direction. The local deformity arising in fractured clavicle has been discussed; but in addition there is falling inward and forward of the shoulder, and projection of the inferior angle and posterior border of the scapula. This is an especially prominent feature of the injury when great over- lapping occurs in lesions in the middle third of the bone. On account of the usually indirect causation of the injury, contusion, if existent, will be found on the shoulder, elbow, or hand, and not at the seat of fracture. Crepitus may not be perceptible until the shoulder is pressed outward and backward, so as to bring the ends of the overlapping fragments together. A loss of function, due to pain induced by movements, and not to mechanical obstruction, is shown in inability to place the hand on the head while the latter is held erect, or to raise the arm so as to hold it out at a right angle with the trunk. In green-stick fractures fixed local pain may be the single symptom, until, in the course of a fortnight, a small nodule of callus is perceptible. This condition must be discriminated from the localized pain and subsequent nodular deformity of syphilitic STER NUNI F R A CT U R E OF T H E C L A VICL. E . 383 periostitis. Fractures near the acromial end of the clavicle simulate dislocation. The vascularity of the collar bone enables union to become quite firm by the end of the third week. Non-union is rare, and, when occurring, produces a very moderate degree of disability. Impairment of function from pressure of exuberant callus on the vessels and nerves behind the clavicle is a remote possibility. The paralysis sometimes attributed to such cause is oftener, perhaps, the result of injurious pressure of a large axillary pad used in treating the fracture. TREATMENT.—Cure, without deformity, of clavicular fractures present- ing much primary displacement, seems, with our present appliances, to be almost impossible. Fortunately the permanent distortion so often left is a cosmetic defect rather than a disability. The probability of permanent deformity after complete fracture renders it wise to desist from too active attempts to straighten the bone of the green-stick fracture, for if complete separation is caused by the manipula- tion greater disfigurement is liable to occur. Straightening should, there- fore, be attempted only with a moderate degree of force, especially as the bent bone may even regain something of its normal shape during the after-growth of the patient. In complete fractures correction of deformity is to be attempted by grasping the Scapula and swinging it around the posterior chest wall toward the median line of the back, and holding its lower angle against the ribs. This procedure tends to carry the acromion and head of the humerus outward and backward, and thus to restore the position of the shoulder, which has been changed by the loss of the support given by the unbroken clavicle. At the same time moulding of the fragments at the seat of fracture should be practised. A similar effect may sometimes be produced by standing behind the patient and pulling the shoulder back- Ward with one hand, while coaptation is secured by pressure with the other hand at the seat of lesion. Good position is usually obtainable by these manoeuvres. The difficulty in treatment arises from the impossi- bility of retaining correct apposition for three or four weeks by apparatus that can be tolerated by the patient and worn during walking. Dorsal recumbency on a firm, level mattress, with the head bent a little forward by a small pillow and the injured arm laid and fixed by a ban- dage or adhesive strip across the chest with the elbows close to the ribs, is the best method of treatment. In this posture the weight of the body keeps the scapula pressed against the chest, and prevents it rotating for- Ward. A bag of shot or sand may, if necessary, be laid upon the acromion to hold the shoulder more firmly outward and backward. The position Qf the arm also aids in maintaining coaptation and preventing over-riding. Few persons, except perhaps women who occasionally dress so as to ex- pose the neck, care to maintain this irksome posture for several weeks, especially when informed of the fact that deformity, though unsightly, is not prejudicial to good use of the arm. Experience, however, seems to show that if this line of treatment is continued for ten days or two weeks the solidification of the fracture becomes such that the erect posture may be assumed, in conjunction with the ordinary fracture dressing, without any great tendency to reproduction of displacement. The best treatment for fºctured clavicle, therefore, is the recumbent posture for about ten days, followed by the ordinary dressings, when the patient is released from his ºnfinement in bed, for about three weeks more. When the least pos- sible deformity is especially desirable, the recumbent posture should be 384 D IS E A S E S A N D J N J U R IF. S OF B O N E S. retained for three or four weeks. Continuous coaptating digital pressure could be maintained for several weeks, if necessary, to insure more abso- lute perfection in the result. The free administration of chloral and bromide of potassium will overcome the nervous restlessness which the requisite immobility of the trunk engenders. g When confinement to bed is objected to by the patient the dressing of Bryant, Sayre, or Velpeau should be adopted. Bryant reduces the fracture and then places a pad over the scapula below its spine and binds the bone firmly to the chest by strips of adhesive plaster, extending from the vertebral spines to the sternum. The arm of the injured side is then supported in a sling, with the hand drawn upward toward the op- posite shoulder. Sayre uses two strips of adhesive plaster about three inches wide and one and a half to two yards long. At the end of one strip a large loop, with the back of the plaster inward, is made by stitch- ing with a needle and thread. After the skin of the chest has been shaved, the injured arm is passed through this loop, which must be loose enough not to constrict the vessels. The elbow is then drawn well back- ward and fixed in that position by the free end of the plaster being carried around the entire chest from back to front, as shown in the illustration. FIG. 179.

This end should also be secured by stitching, if there is any probability of the plaster slipping. The flexed forearm is now laid across the chest and the elbow carried forward, so that the loop of the first strip is made to act as a fulcrum. The middle of the second strip is then applied under the olecranon and the elbow forced upward by carrying the ends of the plas- ter along the forearm and across the back to the opposite shoulder. A slit should be made in this strip at the elbow, to relieve the olecranon of painful pressure, and pieces of lint should be placed under the forearm and in the axilla to prevent irritation from sweating. In cool weather this dressing may require no renewal during the time necessary to maintain immobility. If the fragments project upward notwithstanding the dress- ing, a compress may be placed upon the seat of fracture and held there by a short strip carried down the back and front of the chest. A pad of cloth, covered with plaster with the adhesive side outward, will stick to FRA CTURES OF THE SCAP UL.A. 385 the skin and not easily slip out of position. The hand may be left free, if desired, by passing the second strip along the ulnar side of the wrist. This lessens the discomfort of the dressing. A good dressing in many cases is that of Velpeau. After placing the hand of the injured side on the opposite shoulder, a roller bandage is carried from the scapula of the well side obliquely over the back to the injured shoul- FIG. 181. der, over this, down the outside of the arm, º under the elbow, across the chest to the opposite axilla and to the point of starting. When the arm has been well supported by several turns of this kind, the bandage is carried around the thorax and arm by circular turns from elbow upward. This dressing can be made more se- cure by coating it with silicate of sodium or gypsum, or by applying several narrow strips of adhesive plaster, about a foot in length, ver- tically over its folds. A number of dressings for broken clavicle employ an axillary pad, with the idea that it acts as a fulcrum by which to force the shoulder outward. The pad is probably of little value unless too large and too firm to be worn with Velpeau's dressing for frac- comfort and with safety to vessels and nerves; ture of clavicle. but it may, perhaps, be serviceable if so applied as to act as a compress upon the axillary border of the Scapula and pre- vent sliding forward of that bone. It forms no part of any of the dress- ings recommended above. In children the dressing for fractured clavicle should be continued for two or three weeks, in adults three or four weeks. Fractures of the Scapula. The mobility of the scapula and its environment by muscular masses protect it quite efficiently from fracture under ordinary forms of acciden- tal injury. Fracture, when it does occur, is usually of the body, acromion, ºr surgical neck. The spine and the coracoid process also suffer fracture, but these lesions are of great rarity. The rim of the glenoid cavity is oc- casionally chipped off in dislocations of the head of the humerus, and the Cavity itself may at times be fissured, but the obscurity of the symptoms renders diagnosis almost impossible. In suspected fracture of the body, placing the forearm across the chest or behind the back will render the posterior border of the bone suffi- ciently prominent to enable the surgeon to detect deformity from displace- *nt. Crepitus is best obtained, perhaps, by placing the palm of one hand over the scapula while the patient's arm is moved in various direc- tiºns, or by the examiner insinuating his fingers under the inferior angle of the bone and endeavoring to obtain motion while he steadies the upper Pºrt of the bone with the other hand on the shoulder. The ridges some- times so well marked along the borders and spinous process of the bone, nust mot be mistaken for fracture with displacement. Reduction of the fragments may be difficult but should be attempted by pressure while the patient’s arm is moved in various directions. Broad 25 386 D IS E A SES A N ID IN J U R IE S OF B O N E S. adhesive strips carried across the scapula and partly around the thorax, and a bandage applied to raise the elbow and keep the arm against the side in a more or less vertical position, furnish an appropriate dressing. Union takes place in about four weeks and good use of the limb is to be expected, even if some deformity persists. In open fractures suppuration may occur from bacterial infection, and pus burrow under the scapula. This should be averted by furnishing facilities for drainage as soon as needed. Fracture of the acromion and separation of the acromial epiphysis are lesions often indistinguishable. The two centres of ossification for the acromion appear about the sixteenth year, and Ossification is complete between the twenty-second and twenty-fifth year. Hence, direct violence falling upon the elbow or muscular contraction may easily cause epiphy- seal separation even in adults. The line in acromial fracture is usually either in front of the articula- tion with the clavicle or at the root of the acromion process. Absence of deformity and contusion of the soft parts may obscure the recognition of the lesion. When the process is broken at its base much flattening of the shoulder is produced by the weight of the arm pulling the fragment downward and inward. Less deformity results when the mere tip is broken off. Inability to abduct the arm usually accompanies acromial fracture; and crepitation may be obtained by grasping the shoulder while the elbow is forcibly pushed upward. Fibrous is more common than bony union, probably because close contact of fragments is not obtained. The indication for treatment is to immobilize the arm with the head of the humerus forced well up against the scapula. Velpeau's dress- ing for clavicular fracture answers the purpose very well, and should be continued about four weeks. The least deformity is probably obtained by keeping the patient on his back in bed with the arm extended at a right angle to the trunk, in order to relax the deltoid, which is the dis- placing muscle.

Fracture limited strictly to the constriction immediately behind the glenoid cavity, which has been called the anatomical neck of the bone, F R A CT U R ES OF T H E H U M E R U S. 387 is practically unknown. Fracture may take place, however, behind the coracoid process in a line passing downward from the supra-Scapular notch, or in such a direction as to split off most of the head of the bone while leaving the coracoid process attached to the body of the scapula. These rare lesions are called fractures of the surgical neck of the scapula. The flattened shoulder, prominent acromion, and loss of voluntary mo- tion of the arm make the lesion resemble axillary dislocation of the head of the humerus; but the easy reduction and immediate recurrence of deformity. the crepitation and the absence of the humeral head in the axillary space, establish the distinction. The sinking of the outer frag- ment of the scapula with the attached humerus into the axillary space may mislead the careless surgeon into the belief that a humeral disloca- tion has occurred. The treatment resembles that for fracture of the clavicle, though an axillary pad to keep the arm out and steady the scapula is perhaps more essential in this instance. The downward dis- placement is to be antagonized by a short sling or bandage to lift the elbow. Fractures of the Humerus. These injuries are conveniently grouped as fractures of the upper end, fractures of the shaft, and fractures of the lower end of the bone. FRACTURES OF THE UPPER END OF THE HUMERUs.—The usual lines of fracture at the upper extremity of the humerus are through the ana- tomical neck and tuberosities; at the surgical neck, which is the constric- tion with indefinite boundaries seen below the tuberosities; and at the line of the main epiphyseal cartilage. Fracture of the surgical neck is * FIG. IS5. Fracture through tuberosities of humerus Specimen of fracture of the surgical With head united to the shaft at a lower neck of the humerus.

Fractures of the head alone, of the anatomi- cal neck alone, and of the tuberosities alone are possible injuries; but are *9 rare in occurrence and too difficult of exact clinical recognition to Mºrant discussion in this treatise. The existence of such fracture lines *99njunction with multiple splitting of the upper end of the bone is, of 388 DIS E A SIES A N D IN J U RI ES OF B O N E S. course, not so unusual. Detachment of a portion of one of the tuber- osities by muscular action happens occasionally as an accompaniment of dislocation of the head of the humerus; and is, in fact, a lesion very similar to what has been elsewhere described as “sprain fracture.” Fractures through the anatomical neck and tubercles frequently show little displacement, because the fragments are impacted or are held together by untorm periosteum. There is no evidence that fractures entirely within the capsule of the shoulder-joint fail to unite, or that the superior fragment acts as a foreign body and causes violent arthritis. Sometimes the lower fragment or shaft is drawn upward by the deltoid muscle in such a manner that the upper fragment or head becomes united to the former at a lower level than normal, and gives the joint the appear- ance of being the seat of an unreduced dislocation. FIG. 186. FIG. I.87. § \º § º, § § y § º º § N * - ** : Ž º Diagrammatic fracture of Surgical neck of Separation of upper epiphysis of humerus. (GRAY.) humerus. (MooRE.): The surgical neck of the humerus is frequently broken and sometimes with but little displacement. Fissured lines may extend upward within the articular capsule, and impaction is not unusual. Displacement of the end of the lower fragment inward seems to be the most common deform- ity. Separation of the main epiphysis, which consists of the head and tuberosities, resembles in many respects fracture of the surgical neck; but only occurs previous to the twentieth year of life. When displace- ment occurs there is seen on the front of the shoulder, an inch or so below the acromion, a prominence which on palpation is felt to be a smooth, slightly convex end of bone, moving with rotation of the elbow. It is the upper end of the humeral shaft. Preternatural mobility and soft crepitus may be distinguished. Union of fractures of the surgical neck and of epiphyseal separations occurs in six to eight weeks, and is followed by good results if displacement has been corrected. The injury to the epiphyseal cartilage is sometimes, however, followed by arrest of longi- tudinal growth of the bone. Occasionally, the upper fragment is 80 rotated by the scapular muscles that its under surface looks forward and outward. In such cases apposition may often be obtained by abducting F. R A CT U R ES OF T H E H U M E R U S. 389 the arm and carrying the elbow up alongside of head until the lower fragment becomes interlocked with the upper one. Coaptation will some- times be maintained after this manipulation when the arm is gently depressed again. FIG. 188. Epiphyseal separation at upper end of humerus. (BRYANT.) DIAGNOSIS OF INJURIES ABOUT THE SHOULDER-JOINT,-In investi- gating traumatic lesions in the vicinity of the shoulder, recognition of the fact that fracture exists is more important than a knowledge of the exact variety of fracture. The relation of the bony prominences to each other should be investigated and the correspondence of such relations with that on the normal side carefully established. Acupuncture needles may be employed in obscure cases to determine the location of the bony constitu- ents of the joint. The surgeon should grasp the head of the humerus with the fingers of one hand while he rotates the arm by the other hand applied to the elbow. If a fracture exists between these two points the motion given to the lower end of the bone will not be transmitted to the head unless impaction has taken place. The same manipulation will in most instances of fracture develop crepitus, especially if some extension be used at the same time to draw the overlapping ends into contact. In dislocation of the head of the humerus the shoulder will be flattened, the acromion very prominent and with a depression below it into which the surgeon's finger-tips can be pushed; the elbow will be abducted from the chest, the arm roated inward and the head of the humerus noticeable by palpation in its abnormal location, which is usually the axilla or the fossa just below the clavicle. In addition to these symptoms voluntary motion is lost; passive motion greatly restricted; it is impossible to place the patient's hand on the opposite shoulder while the elbow of the injured side is pressed close to the breast; the long axis of the humerus is not directed toward the glenoid cavity but internally to it; the head of the bone is felt to move when the elbow is rotated; no true fracture crepitus is developed, though a soft rubbing sensation may be detected, and after ºtion the deformity does not occur on removing restraint from the lm O. When the head of the humerus is in its normal position the upper por- ºn of a straight rod laid upon the outside of the arm from shoulder to elbow will be half an inch, an inch, or perhaps more from the edge of the acromion; but if the head is not in the glenoid cavity the rod will *gh the acromion unless very great swelling of the soft parts happens * be present. The following test is given by Hamilton. Grasp the 390 D IS E A SES AND IN J U R IES OF BONES. top of the shoulder so that the commissure between the forefinger and thumb will rest upon the acromion just outside its articulation with the clavicle, and let the finger and thumb fall vertically downward. The anterior digit will, if the bone be in place, rest upon the centre of the head as it projects normally in front of the acromion, while the posterior digit will in a similar manner rest upon its less prominent posterior sur- face. If the surgeon will now move the patient's elbow forward so as to carry the head of the humerus backward, he will feel it press strongly against the posterior digit, thus conclusively proving that the head of the humerus is in its normal position, for if dislocation exists the humeral head cannot be so felt by this manipulation. Fracture of the neck of the scapula with displacement is, according to Hamilton, the only injury that can simulate dislocation during the appli- cation of this test. Exclusion of this unusual fracture, therefore, renders the above tests diagnostic as to the existence or non-existence of disloca- tion. Fracture of the neck of the scapula is distinguished from disloca- tion of the head of the humerus by absence of rigidity during passive movement, which is almost unlimited ; by crepitation, and by the imme- diate recurrence of deformity when pressure which has pushed the arm upward is withdrawn. Fractures of the head and of the anatomical neck of the humerus are too infrequent and too obscure of diagnosis to require further mention than has been previously given. Fracture of the greater tuberosity is unusual also, except as a complication of dislocation. In epiphyseal separation, which occurs not later than the twentieth year, the head of the bone can be felt in its normal position though it does not move with the shaft, the upper end of which lies in front or to the inner side of the head. Soft crepitation is perceptible when the sepa- rated surfaces can be placed in apposition, the elbow can readily be pressed close to the ribs, though the arm is directed somewhat outward and backward, and voluntary motion is lost, but passive mobility in- creased. Fracture of the surgical neck is common, and is therefore the injury in this region which most frequently requires discrimination from dislocation. Displacement similar to that found in epiphyseal separation, the easy demonstration of the head of the bone in its normal position, preternatural mobility and crepitus unless impaction exists, and immediate recurrence of deformity upon removal or support, are the usual features. The symp- toms of fracture of the surgical neck and of epiphyseal separation are very similar, and differ from those of dislocation in almost every particu- lar except that in all three injuries voluntary motion is lost. In disloca: tion this is due to destruction of the articulation and the entanglement of the humeral head in its abnormal position, which circumstance gives an appearance of rigidity to the limb. In fracture or epiphyseal separation loss of active motion results from destruction of the lever through which the muscles act, hence occurs an appearance of helpless inactivity. Any of these fractures at the upper end of the humerus may be com- plicated with dislocation of the scapulo-humeral articulation. The symp- toms of the two lesions will then be a flat shoulder, prominent acromion; and abnormal location of the globular head, combined with abnormal mobility, crepitus, and deformity in the line of the bone. The freedom of passive motion and the ease with which the hand can be placed upon the opposite shoulder while the elbow is pressed to the ribs will differen- tiate the case from uncomplicated dislocation. When the accompanying F. R A CTU. R. E S OF T H E H U M E R U S. 391 fracture is a mere detachment of the greater tuberosity these last two symptoms will not be present. When none of the injuries just detailed have been detected and fracture of the clavicle, acromion, or coracoid process also have been eliminated, the surgeon is justified in making a diagnosis of sprain or of contusion, for about the only other described injury is dislocation of the long tendon of the biceps, the very existence of which lesion is doubted by many. TREATMENT OF FRACTURES AT THE UPPER END OF THE HUMERUs. —The result of these fractures, if of ordinary severity and if displace- ment is overcome, is usually good; though in rheumatic patients a certain degree of stiffness often remains for a long time, even when the joint has not been invaded. The treatment of fractures of the head, anatomical neck, and tuberosities consists in simple restraint of motion, induced by carrying a broad strip of adhesive plaster or bandage once around the arm and chest and placing the hand and wrist in a sling. Violent move- ments to verify a probable diagnosis should be avoided, as any impaction existing may thus be destroyed with the unfortunate result of increasing displacement. In four to six weeks treatment may be discontinued. Other fractures at the upper end of the humerus are best dressed by filling up the hollow of the axilla with a folded napkin or thin compress, and then, after replacing the fragments, Securing the arm against the chest with FIG. 189. the elbow carried a little forward. In this manner the thorax acts as a splint to which the arm is bound by means of adhesive plaster or a bandage. The forearm may be laid across the opposite mammary region as in treating frac- tured clavicle, or may be simply sup- ported in a sling which should preferably be applied near the wrist in order that the weight of the elbow may furnish I "...

Another method is to P" the patient in bed and by means of an extension apparatus of adhesive 392 D IS E A SES AND IN J U R IES OF B O N E S. plaster, a pulley and a weight to obtain continuous abduction and exten- sion of the limb. An elastic cord properly attached to the wall of the room will answer the same purpose as the weight. Counter-extension can be exerted by elevating the foot of the bed or by fastening the patient to the head of the bed by adhesive plaster attached to the chest and shoul- der. In such instances the arm usually has to be kept at an angle with the long axis of the trunk of from 30 to 45 degrees. The dressing may be discontinued in ordinary cases of fracture of the upper end of the humerus in five or six weeks. Gunshot and other open fractures involving the shoulder-joint may demand excision, but conservative antiseptic measures and secondary ex- cisions have of late years displaced to a great extent primary excisions. In fractures complicated with dislocation an attempt to reduce the dislo- cation should be made at once. If this is found impossible, the fracture should be treated and renewed efforts at reduction made subsequent to union of the fracture. If there is definite evidence that such late efforts will be unavailing, even with the advantage of leverage gained by the united bone, endeavors to prevent union and create a false joint at the seat of fracture are justifiable. The disability due to old fractures com- plicated with dislocation may sometimes be lessened by excision of the head or the upper end of the lower fragment. FRACTURES OF THE SHAFT OF THE HUMERUS.–Fracture from mus- cular violence is more common here than in any other part of the skeleton except the patella and olecranon. Displacement in fractures of the shaft depends more on the breaking force than the action of muscles. The usual characteristic symptoms of fracture are present and easily deter- mined. Involvement of the vessels and nerves in the injury is not so very uncommon. Wrist-drop from palsy due to pressure upon the mus- culo-spiral nerve, and gangrene following vascular damage, must not be hastily referred to improper treatment. Union occurs among children in three or four weeks, among adults one or two weeks later. Delayed union and non-union happen more frequently than in other long bones; and is possibly accounted for by the difficulty of completely immobilizing the limb when the fracture is treated with the elbow flexed. FIG. 190. Internal angular splint with changeable angle. In treating these lesions the surgeon should be especially on the alert to overcome rotary displacement. Such deformity can be detected by observing that a line drawn from the greater tuberosity to the outer con- dyle is not parallel to the long axis of the bone as it should be. When much swelling is present, and when a suspicion of complicating injury of vessels or nerves exists, it is wise to keep the patient in bed a few days and employ simple support by pillows and cushions, lest the more constricting dressing be accused of producing gangrene or paralysis. Few fractures of the shaft require continuous extension by weight from the elbow. Frac- F. R A C T U R ES OF T H E H U M E R U S. 393 tures in the upper half of the shaft are well treated, as are fractures of the upper end, by using the lateral thoracic wall as a splint. The thin axillary pad, described in this manner of dressing, may act better if somewhat wedge-shaped and placed with its base downward. In lesions of the lower, and sometimes in those of the upper half, an in- ternal right-angle splint, with or without an external concave splint of pasteboard, leather or gutta percha, makes a good dressing. The internal splint should be well padded at the elbow or have an opening in it to pre- vent pressure on the internal epicon- dyle. The elbow should not be drawn FIG. I 91. upward by the sling used to support the forearm. Sometimes an external angular splint, reaching from acromion to wrist, is preferable. At other times a straight external splint from shoulder to wrist may be found more effective in restraining motion at the seat of fracture, because it better im- mobilizes the elbow-joint. The forearm should be semi-prone when this dress- ing is employed. The gypsum dressing is often satisfactory after primary dis- placement and swelling have been re- a moved. When adopted it should be Splint for fracture of shaft of humerus. applied, with the elbow flexed, from the (BRYANT.) hand to above the shoulder with a few turns of the saturated bandage passing around the upper part of the chest. A forearm sling completes the dressing. FRACTURES OF THE LOWER END OF THE HUMERUs.—The principal fracture lines which may occur at the lower end of the humerus are shown in the diagrams. In addition, the small tubercle on the external condyle, Sometimes called the external epicondyle, may be detached, and in very rare instances a portion of the articular surface of the bone may be chipped off. Of course, comminuted fractures following no definite lines may occur here as elsewhere in the skeleton. FIG. 192. FIG. 193. d Principal fracture lines of lower end of humerus. In studying injuries about the elbow, it should be remembered that there is no lateral motion between the humerus and the bones of the fore- arm. . When the elbow is semi-flexed an apparent lateral motion is ob- servable. It really takes place at the shoulder and not at the elbow, which is a hinge joint alone. Flexion and extension of the joint proper and rotation of the head of the radius are the only possible motions of 394 DISE A SES AND IN J U RIES OF BONES. the healthy articulation. Lateral mobility at the elbow means fracture or some other organic change in the constituents of the joint. Fracture above the condyles may be mistaken for dislocation of the bones of the forearm, and if complicated with vertical splitting may involve the elbow-joint. The most frequent displacement is projection of the FIG, 194. à% !fſº a{ |% §|: :§\ ſ *s§º |;t ~§ !.|º d§* ;:| &ſºi|º} n×} t*ſ- tW}! §§| i i|-| :§:*§;# |*§ ſiº} ºt º&; | s| Diagrammatic supra-condyloid fracture of the humerus.

It is the prominence given the olecranon by this displace- ment that creates a resemblance to dislocation. The normal relation of the olecranon to the condyles, the natural character of the joint motions, the crepitus developed when extension is exerted on the limb, and the recurrence of deformity, establish the diagnosis. Separation of the main lower epiphysis, which, though small, includes both condyles, is rare. In deformity, diagnosis and treatment, the injury differs little from supracondyloid fracture. FIG. 195.

Fractures separating either of the condyles from the shaft necessarily involve the joint, and hence are very important injuries. Such fractures FIG. 196. FIG. 197, FIG. 198. Fracture above condyles of hume- Normal angle of bones of rus. (STIMson.) forearm. (ALLIs.) are common. The essential components of the elbow hinge are the ulnar and the articular surface of the in- ternal condyle. Hence, fractures of the inner condyle are especially dangerous to the future integrity of joint mobility. The ulnar joins the humerus in such { a Way that the axes of the two bones form a diverg- ent angle. This outward deflection of the forearm gives the “carrying function’ to the limb, by which the hand when hanging by the side is enabled to carry burdens without striking the thigh. Loss of Outward deflection of this angle by ascent of the internal condyle or descent forearm. (Stimson.) ºf the external condyle after fractures, greatly impairs theusefulness of the limb. Such displacements are very common, because the line of fracture usually runs obliquely from the margin of the base of ºne condyle down into the articular surface of the same. The condyloid fragment in fracture of the inner condyle is usually displaced upward and backward, and drags the attached ulna with it, thus destroying the divergent angle at the elbow. It is said that a quarter-inch displace- *ent upward will destroy this angular deviation. The anterior or pos- terior right-angle splint often used to dress this fracture is accused, by Dr. 9. H. Allis, of Philadelphia, of being a frequent cause of this dé- formity. He probably is right." He says that such a splint bandaged "Pon the flexed elbow tends to raise the ulna till it lies on the same plane * the radius, while it normally lies below that bone when the elbow is bent.

(ALLIs.) epiphyseal separation and fractures above the condyles may show similar distortion from the use of rectangular splints. Condyloid fractures are occasionally associated with partial or complete dislocation of one or both forearm bones. The existence of mobility and crepitus is to be determined by grasping the lower end of the humerus and the suspected condyle with the fingers of the two hands and endeavoring to move the condyle alternately back- ward and forward. In the fully extended normal articulation a line joining the two FIG. 206. epicondyles crosses the tip of the olecranon, but as flexion is made the olecranon sinks below this line. The position of the head of the radius, one-half inch below the external epicondyle, should also be recollected in order to differentiate dislocation of this bone. If the surgeon places a finger at this point and then rotates the patient’s hand, the head of the radius will be felt rolling under the integument. The transverse diameter of the lower end of the humerus is usually increased § in condyloid fracture, because of the ob- ºW liquity of the line of fracture and the common gº % º tendency in both fractures to upward displace- §§º ment; but it is often difficult to be certain of this widening.

N. D IN J U R IB S OF B O N E S. The term intercondyloid is applied to those fractures in which the con- dyles are split apart and at the same time are separated from the shaft. The fracture lines may be exceedingly diverse in direction, but in simple cases assume an irregular T or Y shape. In intercondyloid fractures, which are, however, not very common, the joint is, of course, implicated; and very often great damage to the soft parts co-exists. Separation of the condyles with the olecranon forced up between them is a not unusual displacement. Great distortion of the joint, increased width of the lower end of the humerus, and crepitation when the fractured surfaces are brought into contact render the diagnosis evident. DIAGNOSIS OF FRACTURES AT THE LOWER END OF THE HUMERUS.— The points in the diagnosis of fractures of the lower end of the humerus need recapitulation. Normally, the head of the radius is about half an inch below the external epicondyle, and unless the shaft of the radius is broken moves when the hand is rotated. With an extended forearm the two epicondyles and the tip of the olecranon are on a level, but as the elbow is flexed the olecranon sinks below this horizontal line. Supra-condyloid fracture with the ordinary backward displacement of the lower fragment shows unusual projection of the olecranon and triceps tendon, increased by straightening the elbow; correction of deformity when traction is made upon the forearm, with recurrence of the same when the traction ceases and the elbow is bent; motion and crepitus above the joint; free mobility at the joint which may, however, be limited by swelling or spasm; normal relation of olecranon and epicondyles. In backward dislocation of the bones of the forearm the unusual projection of the olecranon and triceps tendon is diminished by straightening the elbow, and the point of the olecranon rises above the level of the epicon- dyles; when the deformity is reduced there is a distinct snap and recur- rence of distortion does not readily recur; no motion or crepitus can be developed above the joint, though joint frictien may simulate fracture crepitus; the normal articular movements are almost abolished and the joint is fixed, though some abnormal lateral motion may be possible; the relative position of the epicondyles and olecranon is altered; the head of the radius is not in its proper situation; the distance between the epicon- dyles and the corresponding styloid processes at the wrist is decreased; and the lower end of the humerus feels smoother and wider than the lower end of the shaft in case of fracture. When the lower fragment is displaced forward the question of diagnosis is easily settled, because forward dislocation of the forearm is exceedingly rare and the symptoms characteristic. Fracture of the internal condyle is diagnosticated by crepitus and independent mobility; lateral mobility at the elbow-joint when the fore- arm is extended; and in addition, when displacement is present, change in the divergent angle of the elbow and alteration in the horizontality of the line drawn across the back of the articulation joining the epicondyles and olecranon. If dislocation of the head of the radius coexists, the head of that bone will probably be discovered behind the external condyle, and the internal condyloid ridge of the humerus will be felt to termi- nate abruptly at the line of condyloid fracture. In fracture of the external condyle, crepitation, independent mobility, alteration of the normal lateral deviation of the axis of the limb at the elbow, change of relation with the other condyle and olecranon, but normal relation to the head of the radius, will serve to indicate the nature of the lesion. F. R A CTU. R. ES OF T H E H U M E R U S. 399 The relation to the head of the radius should be carefully studied when outward dislocation of the radius and ulna is a question to be determined. In suspected intercondyloid fractures, great deformity with distortion of relation of the bony landmarks, increase in width of the lower end of the humerus, independent mobility of the condyles and between the con- dyles and shaft, and crepitation, especially noticeable when the olecranon is drawn down and the condyles pressed together, are the symptoms to be sought. ºwest OF FRACTURES AT THE LOWER END OF THE HUMERUS.— It has been the general custom for the most part to treat these fractures in the flexed position with anterior or internal angular wooden splints, or with posterior angular trough-like splints, made of felt, tin, gypsum, or similar material. This is usually an error. The best results will generally be obtained by keeping the joint extended or nearly so during the time that displacement is likely to occur. Ankylosis in the extended posture FIG. 207. Anterior angular splint, with changeable angle. Fig. 208. FIG. 209. Deviating splint for fractures through the condyles of the humerus. is,...I admit, very undesirable, but, unless permanent ankylosis is very cer- tain to occur, disability from the “gunstock” deformity is to be guarded against by keeping the joint extended. Fractures of the epicondyles, Some fractures of the external condyle, fracture of the internal condyle With backward luxation of the radius and ulna, and bad intercondyloid fractures, may perhaps give better results when the flexed position is 3dopted, but for the great majority of cases the extended posture is better. The dressing, then, for fractures at the lower end of the humerus consists ºf a straight wooden splint, twelve or fourteen inches long, placed upon the anterior surface of the arm and forearm, with a little extra padding ºf the bend of the elbow if complete extension of the joint is not desired. The application of a moulded gypsum splint to the anterior or posterior surface, or to the entire circumference of the arm, is sometimes preferable. Four weeks or less is usually long enough to retain the splint upon the limb. In all cases the Surgeon should see that the outward deflection of 400 D IS E A SES A N D IN J U R I ES OF B O N E S. the forearm, due to the obtuse angle between the axes of the arm and forearm, is maintained. It is usually best to have the straight splint cut so as to make a slight outward deflection between the arcs of the upper and lower portions. I have often made such splints from a strip of board with my pocket-knife. It is well to compare the patient's arms, as the normal outward deflection varies in individuals. If the position of extension is uncomfortable, or if there is reason to believe that permanent ankylosis is about to occur, the straight splint may be removed at the end of two weeks and the elbow carefully flexed to nearly a right angle. Should the fragments remain in good position and no tendency to recur- rence of deformity be present, the subsequent treatment may be con- ducted with an angular splint. In very bad intercondyloid fractures and fractures involving the radius and ulna as well as the humerus, ankylosis will almost certainly occur; hence the flexed position here should be adopted more frequently than in other cases. Continuous weight-extension may become necessary to keep the fragments in position. Excision of the joint may be demanded in such fractures, if open. It is better in such excisions to avoid, if practi- cable, removal of the upper ends of radius and ulna, because otherwise the insertions of the great muscles are disturbed. Passive motion should not be made before the end of three or four weeks, and not then if it causes pain. The moderate stiffness, usually left even in favorable cases, will disappear in the course of a few weeks after removal of the splints, especially if active and passive motions accompanied by friction be employed. If inflammatory involvement of the joint has taken place early passive motion will do no good but probably much harm. Fractures of the Bones of the Forearm. Fracture of both bones of the forearm near the middle is quite com- mon, but fracture of the shaft of either bone alone is unusual. When the radius alone is broken the lesion is nearly always situated near its lower end, while the ulna when broken alone nearly always suffers such lesion at the upper end. The clinical phases and the diagnosis of fractures of the forearm will be better appreciated if lesions of similar parts of the ulna and radius are discussed together. .. FRACTUREs NEAR THE ELBow-JOINT.-Hence I shall speak first of fractures near the elbow-joint. This is the method adopted by Stimson in his elaborate work on fractures, from which, I may say in passing, much of the material used in this section on fractures has been obtained. FRACTURE OF THE OLECRANON.—Direct violence may cause the ole- cranon to be broken from the shaft of the ulna, but it is probable that a great majority of these fractures are due to a leverage action consequent upon the triceps holding the process firmly against the lower end of the humerus at the time the impinging force is applied to the forearm. The bone snaps in such cases as a stick is broken by the hands across one's knee. Muscular contraction alone seldom causes this fracture. The location of fracture varies, but most commonly is near the middle of the process, where there is a narrowing. The epiphyseal cartilage, which ossifies about the sixteenth year of life, is placed near the middle of the olecranon; therefore, supposed fractures in young persons may really be F R A C T U R ES OF B O N ES OF THE FOR E A R M. 401 instances of diastasis or epiphyseal separation. The triceps muscle tends to displace the upper fragment upward, but the process is sº attached to the humerus by ligaments, and the tendinous expansion of the muscle so unsheathes it and the adjacent part of the ulna that not much separation occurs unless the forearm is flexed. In fact in many instances no marked displacement takes place even in flexion, because the fragments are bound together by the untorn aponeurosis. Under the opposite conditions a separation of as much as two, and a half inches is said to be possible, but this probably refers to the joint in a flexed, or semiflexed position. The intra-articular effusion that frequently arises and the tendency of the biceps and anterior brachial muscles to draw up the forearm, and thus crowd the humerus into the gap between the ulnar shaft and olecranon, probably have an influence in causing separation of the fragments. EIG. 210. FIG. 211. J)iagrammatic fracture of olecranon. (GRAY.) Fracture of olecranom. (ERICHSEN.) The symptoms are localized pain and swelling, lateral mobility and crepitus, combined with more or less loss of power to extend the fore- arm, and with, in some cases, a noticeable depression at the seat of fracture. The last two symptoms vary greatly with the degree of laceration of the fibrous envelope of the bone. The development of crepitus may require the fully extended position of the joint in order to obtain contact of the bony surfaces. If local pain and impaired extension power alone are present, the case should be treated as an instance of fracture until the subsequent history disproves the suspicion. - Union may be bony, but is generally fibrous. A comparatively long fibrous bond gives but a moderate disability, if there coexist no adhesions of the olecranon to the humerus and no intra-articular fibrous obstruc- tion. This is due to the fact that powerful and extensive flexion is a imore important function of the elbow than complete extension. Ununited racture is not very infrequent. . In ordinary cases cure takes place in about four weeks, and though the . is necessarily involved, there is no tendency to ankylosis of the €l OOW. When separation of the fragments is present the injury should be treated with a splint to keep the elbow extended to that degree which is *en when the arm hangs passively at the side. As ankylosis is not to 26 402 DISE AS ES A N D IN J U R IES OF BON ES. be anticipated, the most accurate coaptation possible is to be sought. This is obtainable only by the extended posture; but the extension must not be so excessive as to bend the joint backward, which is possible when the normal check to such motion given by the olecranon is destroyed by frac.

The upper fragment may be steadied or pulled down if necessary by a strip of adhesive plaster so applied above it that the ends cross each other upon the forearm. An anterior straight splint of wood or metal or a circular gypsum dressing, leaving the elbow uncovered, is then applied from the upper third of the arm to the lower third of the forearm. If e º º | Fracture of olecranon treated in extended position. (AGNEw.) it is impossible to bring the fragments, together by extension alone, the upper fragment, may be drawn down by a single steel hook, similar to Malgaigne's double patella hooks, inserted into the tendon just above the olecranon and attached below to the skin and fascia covering the ulna, or to the gypsum dressing which is applied to keep the elbow extended. Tenotomy of the triceps tendon would be justifiable to overcome upward displacement. The hook should not be applied for three or four days until the inflammation immediately following the injury has subsided, but should be retained in position for four weeks. If there is much pri- mary synovial effusion into the joint, increasing displacement, aspiration is proper. When violent reaction occurs and ankylosis seems probable, passive motion may be cautiously made after three weeks, but is to be omitted if it causes inflammatory reaction. When there is little tendency to separation and flexion does not increase the displacement, the limb may be treated in a semi-flexed position if extension causes discomfort. When great disability has resulted from long fibrous union, great im- provement has been obtained by exposing the bone, freshening the ends, and fastening the fragments together by wire sutures introduced so as not to penetrate the joint. This procedure is justifiable under exceptional circumstances if done antiseptically. F R A CTU. R. ES OF B O N E S OF T H E F O R. E. A. R. M. 403 Fracture of the coronoid process is very rare except as a complication of backward luxation of the ulna or of radius and ulna together; when the process is liable to be broken off by being driven against the articular surface of the humerus. The symptoms are the presence of a small movable body in the line of the tendon of the anterior brachial muscle, crepita- tion, and usually the symptoms of dislocation of the forearm. Displacement from muscular contraction is impossible, unless the line of fracture be below the base of the process, for the tendon is not inserted upon the apex of the coronoid process. A similar reason proves the supposed detachment of this apophysis by muscular contraction an error. Treatment consists in immobilization with a splint or the gypsum bandage - for a couple of weeks with the elbow flexed at a right Fracture of coro- angle or less. A sling should then be worn for ten noid process, and days or two weeks longer. head of radius. FRACTURES OF THE HEAD AND NECK OF THE (BRYANT.) RADIUS.—Of these rare injuries little is known. A splitting off of a part of the articular surface of the head with the line of fracture running down the neck is perhaps the most common form, and is observed in connection with coronoid fracture of the ulna. The fracture may be entirely within the joint; hence synovitis and defect in bony union might be expected. Loss of power of rotation, crepitation, the presence of a movable fragment, and an apparent widening of the head of the radius are the symptoms likely to aid in the diagnosis. The radius may also be broken at the neck just above the bicipital tubercle. Immobilization for three or four weeks in the flexed and supine position, which relaxes the biceps, should be the treatment. FRACTURES NEAR THE MIDDLE of THE FOREARM. Fracture of the Shaft of Both Bones.—When the radius and ulna sustain simultaneous Union, with slight lateral displacement, of fracture of radius and ulna. fracture of the shaft it is usually found that direct violence has caused the injury; and as a rule the radial fracture is nearer the elbow than is the ulnar fracture. Fractures from muscular contraction are occasionally seen. Green-stick fracture is not uncommon. Angular displacement toward the interosseous space, overriding and rotary displacement of the *adius are sources of deformity. The overriding may shorten the limb *Wo or three inches. When the radial fracture is above the insertion of the round pronator muscle, the short supinator and the biceps, which is also * Supinator, have unopposed action; hence the upper part of the bone is supinated, and the lower portion, if it is kept pronated by the Splints will unite with rotary deviation. To avoid this the hand should be kept supine by the splints. - 404 D IS E A SES AN ID IN J U R IB S OF B O N ES. The loss of rigidity of the limb, crepitus, and abnormal mobility render the diagnosis easy. Union occurs in about four weeks, but a high grade of inflammation is not an infrequent complication. Gangrene from con- stricting dressings must be remembered as a possible danger, to which attention may not be called by any discomfort felt by the patient. The comparative frequency of these complications probably arises from the usual causation of the fracture by direct violence. The primary bandage under the splints is to be especially avoided in these injuries. When the two fractures are directly opposite each other, when great laceration or irritation of the interosseous membrane and fibrous tissue has occurred, and particularly when inward angular deformity is permitted to remain uncorrected, mormal pronation and supination are liable to be diminished or destroyed by an osseous bridge soldering the radius and ulna together, or by a protuberance of one or both bones. The prognosis in uncompli- cated cases is good, though delay or failure in FIG. 216. union is not very infrequent. After replacement of the fragments has been obtained by extension and counter-extension and by pressure of the fin- gers in the space between the two bones, the limb should be placed in the supine position, that is, with the palm of the hand upward, and so main- tained by splints until consolidation has occurred. The semi-supine position is often adopted, but as full supination is required to prevent rotary deformity of the radius when it is broken above the insertion of the round pronator, it is safer to teach the adoption of complete supination for all cases of fracture of the shaft. Such a position gives be- tween the radius and ulna almost, if not quite, as much space as the semi-supine position, and hence is as efficient in preventing loss of rotation by bridges of callus. The supine position is most conveniently main- tained by the use of either a right angle wooden or metal splint applied to the flexor surface of the limb from the middle of the upper arm to the root of the fingers, or a right angle trough similarly fitted to the extensor surface of the arm and fore- and jo, between bones arm. A straight palmar and dorsal splint applied in facture of radius and together and extending from elbow to fingers will ulma. (STIMson.) scarcely prevent the limb assuming the semi-supine position, which is more convenient and comfortable to the patient than complete supination. After partial consolidation has occurred, say at the end of two weeks, the two straight splints may be substituted for the angular one, since at that time the risk of rotary dis. tortion is no longer great. In fractures below the insertion of the round pronator such splints may be used from the beginning of the treatment, but must be wider than the arm so that the bandage shall not press the bones together at the site of fracture. The palmar splint is made more comfortable by having the distal end cut off obliquely and well padded for the fingers to close over it. In all these fractures the sling should be broad enough to support both hand and forearm. A narrow sling supporting one part only is liable to permit sagging and angular deformity. This is especially so when the Angular displacement F. R A CT U R ES OF B O N E S OF T H E FO R. E. A. R. M. 405 palmar and dorsal splints are employed. The use of a narrow compress under the splint to prevent encroachment of the fragments upon the inter- osseous space is either unnecessary or inefficient. The circular gypsum dressing is not well adapted to these fractures, though the moulded gyp- Sll Iſl it. are not objectionable. º Daily examination is a wise precaution for the first week, since exces- sive inflammatory swelling and a tendency to displacement are frequent accompaniments of these injuries, The splints may be removed in four weeks. Extreme overriding may require the adjustment of continued extension. In cases kept in bed this may be effected by a weight and pulley; in walking cases by elastic bands attached to a splint prolonged beyond the hand. Shortening is not a matter of much moment except when due to such overriding as may impair rotary motion by encroaching upon the interosseous space. TIG. 217. w º wº \ . Wyº º, Yºğs Ä Ş &ū .

FRACTURE OF SHAFT OF ULNA.—If the radius is neither broken nor dislocated, shortening is not possible in fracture of the ulnar shaft. Lateral or angular displacement is readily discovered because of the sub- Qutaneous position of the ulna. Alternating pressure above and below the supposed fracture, or grasping the two portions of bone firmly with the fingers and endeavoring to move them in opposite directions will usually prove or disprove the existence of crepitus and mobility. If the tip of the olecranon be quickly tapped with the fingers of one hand while the lower end of the normal ulna is grasped with the fingers of the other hand, the transmission of the vibration along the entire length of the bone will be readily felt. In a broken bone this transmission will be much less perfect. Attempts to twist the arm may develop crepitus otherwise not easily elicited. Forward dislocation of the head of the radius is said to be a not unusual complication of ulnar fractures, and may be overlooked. Moulding by digital pressure is the only efficient agent for correcting splacement, and must be so exerted as to avert infringement of the *9sseous space by angular deviation of the fragments. The same *ēsing as that described for fracture of the shafts of both bonesis appli- cable, though complete supination is not demanded as in the former case. he prone position is not allowable, but the semi-supine will often do as *. *the supine. In most cases the elbow joint had better be controlled. he circular gypsum dressing is often very convenient and efficient. If di 406 ID IS E A S E S A N I) I N J U R I ES OF B O N E S. the posterior gutter of felt or metal is used, it is important that it should support the ulna along its entire shaft as well as at its ends, lest sagging occur at the seat of fracture. The splints should be kept on about three weeks. FRACTURES OF THE SHAFT OF THE RADIUS.—The function of the radius as the movable segment of the forearm, to which the hand is attached, gives great importance to this fracture and warrants a guarded prognosis. Displacement is liable to be angular, forward and toward the ulna, and the supinating muscles have a tendency to supinate fully FIG. 218. the upper fragment if the solution of continuity occurs § N above the round pronator's insertion; while the hand * } and lower fragment tend to take the prone position. $º Marked displacement of the lower fragment at its upper \},\, \'ºſº, end toward the ulna alters the plane of the lower articular \ } face of the bone and gives the hand an abnormal devia- W | tion toward the radial side.

If the hand is much displaced extension of the ulnar side may be valuable in obtaining and maintaining correct apposition. In accompanying dislocation of the lower end of the ulna extension by some such device as that figured under fracture of both bones may be necessary. Motion of the hand and elbow had better be controlled in most cases. At the end of three weeks the splints may be discontinued and a simple bandage used. º Fractures near the Wrist-joint. FRACTURE OF THE Low ER END OF THE RADIUS.—This exceedingly common fracture was long misunderstood and is still very often improperly treated. It is frequently designated by the name of one or other of those writers who have discussed it, but I shall not mention the names, Since such momenclature serves to confuse the student and to perpetuate erroº neous teaching. The usual fracture line is situated from one-third, tº three-quarters of an inch above the articular surface of the bone; and is generally more or less transverse in direction, though some tendency * lateral or antero-posterior obliquity is not infrequent.

(LEVIs.) radius is carried upward and backward by this displacement; and, there- fore, in fracture of the lower end of the radius the radial styloid process is often on the same level as, or even higher than, the ulnar styloid process. FIG. 221. Diagram of displacement in fracture of lower end of radius. (LEVIs.) This angular displacement tends to throw the articular surface with the attached garpus upward, backward, and to the radial side. Hence occur the peculiar deviation of the hand and the under prominence of the lower end of the ulna, which gives such a characteristic appearance to the limb 408 I) IS E A S E S A N ID IN J U R IB S OF B O N E S. after this injury. The hand is, as it were, carried away from the ulna by the force which breaks the radius and displaces the lower fragment. Sometimes the ulna is actually forced through the integument by the vio- lence with which the hand is forced away from it, on account of the forc- ible shortening of the radius. Such a wound, however, does not necessarily create an open or compound fracture, for the wound does not always com- municate with the fracture. Prepared specimens of united fractures give perhaps a false notion of the amount of impaction originally existing, because the formation of callus beneath the stripped-up periosteum or the dorsal surface is misleading. FIG. 222. An old fracture of lower end of radius united with deformity uncorrected. (ERICHSEN.) The wrist joint is not involved unless, as often happens, longitudinal lines of comminution divide the lower fragment or base of the bone into more than one piece. Fracture of the lower end of the ulna, or of its styloid process alone, and rupture of the radio-ulnar ligaments and carti- laginous attachments are occasional associated lesions; but, as a rule, fracture of the base of the radius is uncomplicated except by commi- nution. In young persons epiphyseal separation, with a causation and deformity similar to that which pertains to fracture, may occur. The treatment of the two injuries is identical. FIG. 223. Vertical section of fracture of lower end of radius, showing usual backward displacement. (R. W. SMITH.) The fracture just described is practically the only one that occurs at the lower extremity of the radius; though in rare cases irregular fracture lines splitting off the radial or ulnar side of the base by lines more or less vertical running into the joint have been described. Displacement forward of the lower fragment, that is, displacement toward the palmar surface, has been described as occurring after transverse fracture above the joint when the force has been received upon the back instead of, as usually, upon the palm of the hand. The uniformity of the lesion produced when the radius is broken at the wrist shows that the mechanical conditions causing the fracture are usually F. R A CT U R E S N E A R T H E W R IS T J O IN T. 409 the same. When a man falls either forward or backward his arms are ex- tended to protect himself, and the violence consequently is received on the palms of the outstretched but not completely pronated hands. The force is thence transmitted to the radius which is concave on its palmar surface. Fracture occurs across this concave portion of the bone: 1. Because the arch has strain brought upon it, and is by nature a weak part of the bone. 2. Because there is a cross-breaking force exerted here, when the hand is violently extended backward, by the ligaments on the palmar aspect of the joint; the end of the bone is thus torn off. 3. Because penetration and crushing of the cancellated osseous tissue is caused by the lower end of the bone being driven against the shaft. Stimson thinks that the first theory is a better explanation of the usual mechanism of the fracture than the others, though he admits that the lesion may be caused in all three ways. I am inclined to believe in the truth of his argument. The symptoms of the fracture are so marked that, in a typical case, error in diagnosis is impossible, if it is only recollected that dislocation of the radio-carpal joint is exceedingly rare. The deformity of the fracture so resembles that of backward dislocation of the carpus that the fracture has at times been called a dislocation. This error has received apparent confirmation from the fact that after the displaced lower fragment is |pushed into position, there is little tendency except in comminuted fractures, to reproduction of the deformity. The transverse character of the break, and the absence of muscular displacing causes render secondary displacement almost impossible unless the wrist is subjected to consider- able violence. Let the student recollect that injuries of the wrist sug- gesting dislocation of the carpus are nearly always fractures of the lower extremity of the radius. SYMPTOMS.—The characteristic distortion has given the name “silver fork fracture” to the injury. The hand is apt to be held semi-prone. Voluntary movements of the wrist are painful, and hence are lost, though finger motions are but slightly impaired. On the radial side of the back of the wrist there is a prominence, the upper margin of which Can sometimes be felt as a sharp bony edge. The radial extensor tendons may sometimes be felt stretched across the space between the shaft and the upper portion of this prominence, which is, of course, the displaced lower fragment. Forced flexion of the hand will render these tendons more tense and therefore more easily perceived. On the palmar surface of the wrist there is a transverse furrow behind the ball of the thumb, and behind that a prominence due to the lower end of the upper fragment and the inflammatory effusion which takes place into the sheaths and tendons of the flexor mass of muscles. The hand usually deviates some- What to the radial side, the ulna is unduly prominent on the posterior and ulnar aspect of the wrist, and the styloid process of the radius is on a level or even higher than that of the ulna. Mobility and crepitus are often absent because of impaction; though both may be developed by *ong pressure upon the dorsal prominence, which at the same time forces the displaced portion of the radius into position with a sensation of *PPing or grating. In comminuted or unimpacted cases motion and 99pitºls are often easily detected. Motion at the wrist joint or in the “ºpal articulations may be mistaken for fracture mobility. When no displacement occurs there may be no distinctive symptoms except a tender *P* upon the bone, which cannot be attributed to arthritis as it is a little above the known location of the joint. 410 I) I S E A SES A N D IN J U R I ES OF B O N E S. DIAGNOSIS.–The diagnosis must be made between sprain of the wrist, fracture of the lower end of the radius, and dislocation of the carpus. If no deformity such as described above exists, it nevertheless may be a fracture with little laceration of the periosteum and no appreciable dis- placement. The diagnosis then hangs upon the character of the vul- merating force, the age of the patient, and the position of the tenderness on pressure. If the patient is beyond middle age, has fallen heavily on his palm and complains of localized tenderness about half an inch above the joint, fracture is the probable lesion. If the point of tenderness is over the wrist-joint, if the patient is young, or if the fall was a slight one, a sprain with subsequent arthritis is the most likely injury. When the usual displacement backward of the lower fragment has taken place, an error is impossible after a careful examination, though it is true that the swelling of severe sprain does sometimes simulate the deformity of fracture. Backward dislocation of the carpus is the only luxation resembling fracture, and any dislocation about the wrist is exceeding rare. Backward dislocation would show no change in the relative position of the styloid processes to each other, would give a smooth, laterally convex upper border to the dorsal prominence, and would be reduced with a smooth snap rather than with a rough grating. Deformity would probably be more easily reproduced than in the usual non-comminuted fracture. Dis- location of the radio-ulnar joint would give a very different distortion from that of fracture of the base of the radius. In a person of fifteen to twenty years, epiphyseal separation is to be expected rather than fracture. The exact diagnosis is, however, unim- portant, for the treatment is identical with that of fracture. Inter- ference with the future growth of the bone may perhaps follow epiphyseal separation. TREATMENT.-The essential point in the treatment of this fracture is early and complete replacement of the lower fragment. The protracted convalescence and frequent stiffness of the wrist and fingers seen after this injury are due to imperfect reduction of the fracture and the confine- ment of the fingers during the use of the fracture dressing. When there is neither comminution nor loss of tissue by crushing, the fracture can usually be cured in three to five weeks with little or no deformity, and without stiffness of the fingers. When comminution and crushing exist, cure without impairment of motion, though perhaps with more or less persistent deformity, is nearly always possible, and in the same time. When I say “cured,” I do not mean that every vestige of swelling and of osseous thickening disappears so soon, but that the limb is capable of per- forming its ordinary functions. Old and rheumatic patients may perhaps exhibit a greater tendency than others to rigidity of the joints; but I cannot insist too strongly on my belief that stiff fingers are usually an indication of imperfect reduction of the fragments, which by their pro- jection interfere with the extensor and flexor tendons and cause adhesive inflammation. No apparatus should be applied that restricts, at any period of the treatment, full and free motion of the fingers. In uncompli- cated cases the splint need not be worn more than about ten days; pl.0- vided that the patient is sufficiently intelligent to avoid submitting. the arm to unexpected strains and blows. This is because of the slight tendency to reproduction of deformity in the properly reduced fracture. In careless patients, and in comminuted or otherwise complicated fracturº support by the splint should be continued for three weeks. Uncompli. FRACTURES N E A R T H E W RIST J O INT 411 cated cases in intelligent persons may be treated without any splint whatever. A band of adhesive plaster, or a roller bandage applied firmly around the wrist at the seat of injury, is all that is necessary after perfect reduction has been accomplished. Passive motion is probably never necessary if the fracture is properly replaced, and the play of the fingers not restricted during the use of the splint. Reduction is always painful, but is usually so quickly accomplished that an anaesthetic is seldom needed. Ether or nitrous oxide should be employed, however, if there is likelihood of the pain preventing perfect coaptation of the parts. The surgeon must apply force directly to the frag- ments. Let him put the patient's hand in the prone position, grasp the middle of the forearm with one hand, and take hold of the patient’s palm with the other hand in such a manner that his thumb can make strong pressure upon the apex of the dorsal prominence. By making traction on the hand of the patient and then suddenly flexing the patient's wrist, while at the same time he presses with his thumb strongly upon the pro- jection at the back of the wrist, he can nearly always force the lower fragment into its proper position without difficulty. A repetition of this manoeuvre is sometimes requisite before accurate replacement is obtained. The grating produced as the fragment, which may have been impacted, is driven into its normal position, can at times be distinctly heard by bystanders. The limb at once assumes its normal contour. The disap- pearance of the bony edge or shoulder previously perceptible to the touch where the upper margin of the lower fragment was elevated above the level of the shaft of the radius, is an indication that reduction of the backward displacement has been accomplished. Still further manipula- tion may occasionally be necessary to reconstruct the normal outline of the radius, which has at the wrist, it will be remembered, a concave palmar surface, If great comminution or crushing has been incidental to the fracture, Perfect restoration of shape may be impossible, although the deformity can be greatly diminished. In such cases, also, retention of the fragments in good position may be somewhat difficult. Firm impaction or entangle- ment of the fragments in the tendons or dorsal periosteal bands may require that the hand and attached lower fragment be first bent strongly backward, in order to release the interlocking before making traction, flexion, and pressure. This preliminary measure is not often necessary. After reduction has been accomplished any form of dressing is allowable provided it immobilizes the limb, does not tend to obliterate the normal Qºrve of the palmar face of the radius, and permits the patient to move his fingers. It was formerly thought that splints deflecting the hand to the ulnar side exerted traction on the radial side of the wrist, and were therefore indicated. This is incorrect teaching. Such splints are unneces. Šary, as the deflection only causes the carpus to roll in the articular sur- face of the radius. The hand should be placed in the prone or semi-prone Pºsition, and a single splint, extending from below the elbow-joint to the *iddle of the metacarpus, applied either to the dorsal or palmar aspect of the forearm. It is essential that the palmar splint, if it be chosen, should °99nvex on its upper surface at its carpal extremity, so as to preserve the integrity of the radial concavity and not to make the palmar surface of the radius flat, by forcing upward the lower fragment which has just been pushed down into proper position by the surgeon's manipulations. his Cºnvexity may be obtained by using the moulded splint of Levis, ** splint of wood with a hard convex pad to fit into the palmar concavity 412 ID IS E A SES AN ID IN J U R IES OF B O N E S. of the radius. It should be seen that the pad properly fits. The surgeon can readily make a pad out of soft wood and fasten it with screws to a straight splint. No dorsal splint is needed with either of these splints, FIG. 224. Normal centre of bone. Lower fragment pushed by splint, É Splint. Showing injurious effect of straight palmar splint in fracture of lower end of radius. If it is inconvenient to obtain a proper form of curved palmar splint a flat splint may be applied to the dorsal surface of the radius, which presents no curve but is straight. Bond's splint, so frequently employed, is dangerous to the future contour and utility of the limb, and should never be used. After the splint has been employed for from a week to ten days, varying, as above stated, with the kind of fracture and disposi- tion of the patient, it is well to substitute it by a strip of adhesive plaster, two inches wide, applied circularly around the wrist so as to give moderate support to the partially consolidated fracture. £º jš §§§ s ºs: v ############ Eº §§§s sºsºsºse: § ºffl E- * * * * §§ šºš-šā Š - ----- > 5 Mºsso º S- ºš $ Tºš - - -, * šº *-º-º-º-º-º: :- E. º º Levis’s metal radius splint. If union has already occurred in a fracture treated without proper reduction the surgeon should attempt refracture and adjustment even after the lapse of several months, provided that the fingers were very rigid or the deformity very great. It is not likely that as much can be accomplished in such cases as was possible immediately after the receipt of injury, but proper reduction should be undertaken even at late periods. F. R A CT U R ES OF T H E M ET A C A R P U.S. 413 Good use of the hand is often obtained finally even where there exists a considerable degree of deformity. Rigidity of the fingers if permitted to occur remains, however, for many months. Refracture for correction of deformity is readily accomplished if the surgeon will bend the bone across his knee. Osteotomy need not be undertaken. OTHER FRACTUREs NEAR THE WRIST-JOINT.-Fracture of the styloid process of either the ulna or radius occurs, though rarely. The diagnosis is not difficult. All that is needed for treatment is such a dorsal or palmar splint as will prevent motion, at the wrist and fix the hand in a deflected position; toward the ulnar side in fracture of the ulnar styloid process, toward the radial side in fracture of the styloid process of the radius. A circular gypsum dressing will probably best meet the indica- tions. Fracture of the lower end of the radius, with displacement for- ward—that is, toward the palmar surface has been mentioned as a rare form of injury, due to receipt of violence on the back of the hand. It should be treated with the same form of splints as is the common fracture at the lower end of the bone; but of course the primary reduction is to be made by pressure in an opposite direction. Fracture of both the radius and ulna just above the joint occasionally happens. It, in appearance, much resembles backward luxation of the carpus, but is distinguished therefrom by crepitus, mobility and the preservation of the normal relation of the styloid processes to the bony landmarks of the hand. The treatment is similar to that of fracture of the lower end of the radius, but this injury must not be treated without a splint, as some forms of the latter injury may be. In instances, how- ever, where the line of fracture is some distance above the joint, the lesion partakes of the characteristics of fracture of the shafts of the two bones and should be treated as such, in order to preciude the possibility of callus interfering with future supination and pronation. Fractures of the Carpus, Metacarpus, and Phalanges. FRACTURES OF THE CARPUs.-Uncomplicated fractures of the carpal bones are rare, though it is probable that they occur at times in connec- tion with radial fractures and other injuries, but are unrecognized. The diagnosis must be made by the presence of crepitus or deformity. Pre- ternatural mobility, unless very marked, could be determined only with difficulty in a region containing so many movable bony components. Ankylosis of some of the intracarpal articulations seems a probable con- sequence of carpal fractures, but it would cause little disability. Crush- ing injuries, due to direct violence, and causing extensive lesions of the soft parts, quite often produce open and comminuted carpal fractures. Such cases, however, do not derive their importance from the broken carpal bones. FRACTURES OF THE METACARPUs.-The so-called metacarpal bone of the thumb is not included in this discussion because it is anatomically a phalanx. Its fractures are included, therefore, under fractures of the Phalanges. Metacarpal fractures are generally caused by direct violence received on the dorsal or palmar aspect of the hand; or by force so applied to the anterior extremity of one of the bones as to exaggerate its normal *Ye. To the latter mechanism is due the occasional breaking of a ºnetacarpal bone when a man strikes a violent blow with his fist, receiv- *g, of course, the impact on his knuckles. The common displacement is 414 D IS E A SES A N D IN J U R IB S OF B O N E S. angular with the projection of the angle toward the back of the hand and the anterior end, or head, of the bone prominent in the palm. Lateral overriding is not an unusual feature. The single epiphysis of the bone which is at the anterior extremity, may be torn off in patients not over twenty years of age, and give the symptoms of true fracture. When firm pressure is made in the palm, pain, yielding, and the occur- rence of a prominence on the back of the hand will, as a rule, be de- veloped in those cases of metacarpal fracture that are not at once clearly demonstrated by the ordinary symptoms. A sharp pain at the seat of fracture can often be produced by taking hold of the finger, attached to the metacarpal bone supposed to be injured, and suddenly pushing it toward the wrist. Actual shortening of the broken bone is often quite as characteristic as motion and crepitus. Union takes place in about three weeks. Traction of the finger and pressure, upon the dorsal prominence are sufficient to overcome the displacement in the majority of cases. If no tendency to recurrence of deformity exists, a layer of cotton in the palm and another on the back of the hand, held in position by a circular bandage, constitute an efficient retentive apparatus, though care must be observed lest lateral displacement be caused by the bandage. In other cases support to the fragments and the adjoining bones, and prevention of deformity is best obtained by placing a cylinder of wood, a roller bandage, or a spherical object, such as a billiard ball, in the palm, and keeping the flexed fingers closed upon it by strips of adhesive plaster carried from the back of the wrist, over the knuckles, around to the palmar surface of the wrist. Longitudinal splints applied to the palm or dorsum, or both, and con- trolling the wrist and fingers, may be preferable in some cases. In other instances short transverse splints placed across the back and front of the hand may be found more efficient in meeting the indications. When the tendency to overlapping is marked, no method is as good as continuous extension. This can be done by the use of adhesive plaster strips applied to the back and front of the finger, and a rubber cord extending from the loop of plaster to a nail or screw in the end of a long palmar splint firmly adjusted to the forearm and hand and extending beyond the finger-tips. This method is identical with that used in fractures of the thigh-bone. FRACTURES OF THE PHALANGES.—As these injuries are generally caused by direct violence, they are frequently complicated by comminu- tion, dislocation, and great laceration of the soft parts. The phalanges and the so-called metacarpal bone of the thumb, which, properly con- sidered, is a phalanx, are developed from two Ossific centres; one for the shaft and one for the posterior extremity, or base. Epiphyseal fracture is, therefore, a possible lesion in persons not over twenty years of age. The swelling after phalangeal fracture often conceals the deformity to such an extent that mobility and crepitus are the chief diagnostic features. The prognosis is good except when great comminution or the occurrence of suppuration renders necrosis probable. Quite firm union may be ex- pected in about two weeks if the fracture is uncomplicated. e Lateral and rotary deviation is to be corrected with especial care in phalangeal fractures, for a crooked finger is not only unsightly, but may interfere with the manual dexterity of an artisan. Bowing of the middle of the phalanx toward the palm tends to prevent the patient grasping ob: jects firmly and must be avoided. If ankylosis is apprehended the finger should be slightly flexed during treatment, for stiffness in the partially- F. R A CT U R E S OF THE FE M U R . - 415 bent position is the least inconvenient and least noticeable. A splint of gutta percha, pasteboard, felt, copper, or zinc moulded to the palmar sur- face of the member and to the finger-tip is a neat and effective fracture apparatus. If the proximal phalanx is the seat of lesion, such a splint should include the palm and wrist. A cylindrical pad in the palm, with the fingers closed over it, and kept so fixed by adhesive plaster, as de- scribed under fractures of the metacarpus, is often a good dressing. A FIG. 226. Gutta percha splint for finger. (HAMILTON.) straight palmar splint, the circular gypsum dressing, or continued exten- sion by a rubber band may, in certain circumstances, be more advanta- geous. If necessary, the finger or fingers adjoining the broken one may be used for giving lateral support, or two or three fingers may have to be kept motionless by a wide splint in order to immobilize the injured member. Amputation is frequently demanded in fractures of a complicated character. Conservatism, however, should be the rule, for a portion of a finger or a stiff one is often better than none. Especially is preserva- tion of the smallest apology for a thumb desirable in order that the patient may have something to oppose to the other fingers when grasping objects. While it is true that in certain mechanical operations a deformed or im- movable finger may be an annoyance and disability, and while recovery will in many cases be sooner attained by amputation than by conserva- tive attemps; still the latter course is to be advocated in doubtful cases. Unexpectedly good results are often secured, even when joints are in- Volved, and the patient learns to manipulate with the disabled hand, Which moreover preserves its complete integrity. The risks of prolonged Suppuration and of other secondary troubles which may follow conserva- tism, are practically annihilated by antiseptic methods. After cure is complete the mechanic can test the utility of the hand for a few months, and then, if the deformed finger is a detriment to bread-winning, it may be removed by amputation with little risk. Fractures of the Femur. FRACTURES AT THE UPPER END OF THE FEMUR.—Of these there *e fractures of the neck which may involve the greater trochanter or head, fractures detaching the greater trochanter, and fracture through the base of the trochanter and upper end of the shaft.

Fracture of the trochanter is the result of direct violence, and is to be diagnosticated by displacement of the fragment, character of the injury, local pain, and absence of the symptoms found with fracture of the neck of the femur. Epiphyseal detachment may be suspected in such cases if the patient is not over eighteen years of age.

Hooks similar to those employed for fracture of the patella would not be improper if the displacement was very marked. Fracture more or less transverse through the base of the trochanter and upper part of the shaft is said to occur. Its diagnosis is uncertain, but its treatment is the same as for fractures of the neck. Fractures of the femoral neck are very common and very important surgical lesions. The classification of Stimson seems to be the best. He divides them into fractures of the small part of the neck, and fractures at the base of the neck. The former is identical with the class often called intracapsular fractures, and includes the rare condition, separa: tion of the epiphysis of the head; the latter includes both the so-called extracapsular fractures and those which are partially intracapsular. The reasons for rejecting the old classification are: that the neck is entirely covered by the capsular ligaments in front and below, while behind and F. R A C T U R ES OF THE FEM U R . 417 above only about three-fourths of its length is so covered, and that the extent of capsular envelopment varies in different persons; that the synovial membrane does not extend as far out upon the neck as does the the capsule, hence a part of the neck is extra-articular though really intra-capsular; that the line of fracture FIG. 228. is frequently not confined to either the intra- or extra- capsular portion of bone, and that the clinical diagnosis between intra- and extra-capsular lines is often impos- sible; as can readily be understood by what has pre- ceded. Even at the autopsy the fact of a given fracture being intra-capsular, or rather intra-articular, for it is the relation to the joint that is important, can only be known by accurate examination of the synovial membrane. This is further complicated by the fact that, after fracture, the outer portion of the cavity of the joint may, it is said, be obliterated by adhesion of the capsule to the periosteum. Impaction and fixation of fragments at the first receipt of injury is very frequent in fractures at the base of the neck, and not infrequent in those of the small part of the neck. Attempts at walking, im- proper surgical manipulation, and other secondary violence often cause undesirable separation of the inter- locked fragments. Cervical fractures of the femur are Fragºre of epi- often due to slight injuries, as a twist from catching physis of great tro- the foot in a fold of carpet, missteps, and insignificant chanter and frac- falls on the knee, buttocks, and side of thigh. It is ture of condyles. possible that in certain positions muscular efforts to (Agnew.) avoid falling may be a factor in causing the fracture. An important element in their production is weakening of the osseous tissue by senile degeneration which begins at about the fiftieth year of life, and is said to be more marked in women than • in men. This degenerative change is the predis- FIG. 229. posing cause which permits slight injuries to have - such a disastrous effect. It is not a relative in- crease of earthy constituents that renders the bone more friable; but an actual thinning of the wall of the femur, and also an increase in size of the Spages found in the bone for vessels and fat. The radiating and arched lines of compact bone which Cross the cancellous portion of the bone, and Which are so readily demonstrated by section of he upper end of the femur, are thus absorbed.

Potent factor in the frequent occurrence of frac- *śs of the femoral neck than the change of angle between the shaft ºnd neck which has been said to occur with advancing age.

In other cases not only is the periosteum completely torn and the fragments separated, but the capsule itself rent by the violence FIG. 230.

The displacement is usually of the shaft upward. In impacted fractures some degree of twisting deformity may exist. The shortening of the limb from dis- placement is apt to increase gradually during the first week, but rarely exceeds one inch, except when, after weeks have elapsed, absorption of the neck has taken place. When these fractures are repaired it is usually accomplished by fibrous tissue. Indeed, it has been asserted that bony union never occurs. Such statements are erroneous, though it is true that failure of union or fibrous union is the most common result of the reparative attempts. Bony union does occur, though rarely. The question is of little clinical importance, since a short fibrous bond gives as useful a limb as an Osseous one; and union should always be sought by treatment, if the patient's condiition will permit the necessary confinement. Examination of specimens, with or without a history of fracture, does not throw as much light on the question as would be supposed, because the arthritic changes of old age and interstitial absorption of the neck of FIG. 231.

F R A CT U R ES OF T H E FE M U R . 419 The cause of such frequent defective union appears to be want of contact between the fragments, imperfect immobilization, and some consti- tutional peculiarity. The difficulty of obtaining perfect contact and immobilization when the small upper fragment is so inaccessible and floats in such a cup-like cavity as the acetabulum, will be easily understood. The error of rude manipu- FIG. 233. lation, by which impacted fragments may be sep- ãº. o o ºğ º arated, is a useful lesson taught by this statement. £º, § It would seem that the constitutional tendency, already mentioned as a cause of the extreme fragility of this part of the skeleton in aged per- sons, would tend to interfere with the occurrence of Osseous repair. These reasons for defective union seem to be sufficient without recourse to those often given : namely, deficient blood supply to the upper fragment, and contact of the frac- tured surfaces with the synovial fluid. These §§§ agencies, however, possibly exert some influence. º; The symptoms and diagnosis of fractures of the # §§ small part of the neck will be discussed with simi- ſº lar topics relative to fractures at the base of the Upper fragment driven neck. The usual result after fractures of the into the trochanter frag- small part of the femoral neck is disability with ment. (Gross.) eversion, and some shortening of the limb. The patient in some cases can walk without crutch or cane, but such a slight degree of lameness is uncommon. Occasionally, feebleness from pain, confinement, and age, renders the unfortunate patient bedridden. In fractures at the base of the neck the line of fracture shows a ten- dency to separate the neck from the shaft in the vicinity of the inter- trochanteric line, but may be varied or complicated by lines running downward into the shaft, splitting off the lesser trochanter, extending along the neck toward the head, or involving the upper portion of the great trochanter. Bending the neck backward, with crushing or penetration near the posterior part of the greater trochanter, is said to be a very Common form of the injury. Various degrees and forms of penetration and impaction of the cervical into the trochanteric fragment have been described. The trochanteric fragment or shaft is seldom forced into the cancellated structure of the neck. These fractures usually unite by bone, and in six or seven weeks; showing, therefore, much better reparative effort than fractures of the narrow part of the neck. SYMPTOMS.–The distinctive symptoms of fracture of the neck of the femur are motor disability, eversion, shortening, and crepitation. To these may be added certain incidental symptoms that occasionally assist in the diagnosis. The limb is usually so helpless that no voluntary effort can lift it from the bed, nor can the weight of the body be borne upon it in the erect Pºsition. Sometimes slight elevation of the thigh is possible, especially if the patient can get a purchase on the bed for his heel. In very excep- *onal gases walking on the injured limb has been possible. Here firm *P*ction has almost certainly existed. In making a differential diagnosis ºpenes following severe sprain or contusion must not be for- gotten. The posture assumed by the limb is almost pathognomonic. It lies, as the patient rests on his back, upon its outer side with the little toe almost 420 D IS E A S E S A N D IN J U R I E S OF B O N E S. or quite touching the mattress, and the heel on a level with the space between the inner malleolus and point of the calcaneum of the other foot. A slight degree of flexion and abduction at the hip is quite usual. This eversion is probably, in the main, the result of gravity being unresisted by the normal supporting agencies of the limb rather than due to the action of the external rotators or other muscles. In some cases the ever- sion is slight, at other times the toes point directly upward, while in rare instances actual inversion exists. Angular deformity at the seat of frac- ture, crushing, impaction, and interlocking of fragments and entanglement in capsular rents have probably an agency in the production of the vary- ing degrees of eversion and inversion. Eversion is the usual position and is very suggestive of fracture, though it has been observed in simple injuries of the hip. The normal position of the limb, indeed, when the recumbent posture on the back is assumed, is eversion, and especially so when the knee is flexed even slightly. It is well to compare the injured limb with the uninjured one to determine whether eversion is apparent or real, whether the extent of possible eversion at the surgeon's hands is greater or less on the injured side, and whether the supposed fracture interferes with or increases inward rotation, such as is possible in the sound limb. Inversion has been described as occurring in some cases only after the lapse of a day or two from the time of injury. Violent manipulation to determine these points is not justifiable, since other symp- toms are available for diagnostic purposes. Shortening occurs in cervical fractures of the femur from overriding, and from alteration of the angle between the shaft and the neck. It varies from a mere fraction of an inch, to two, three or even four inches. It may exist to its greatest degree immediately after the injury, or may gradually increase with the lapse of a few days. It has been noticed to occur suddenly, when little or no alteration in length was apparent at the first examination. Great shortening (13 to 3 inches) occurring immediately is rather in- dicative of fracture at the base of the neck, while slight immediate shortening followed by increased shortening is more characteristic of frac- ture at the small part of the neck. The now well-established fact that femurs and tibias are often of un- equal length in persons who have never sustained injuries to the bones of either limb greatly lessens the diagnostic importance of shortening. If a limb which is a half-inch or one inch longer than its fellow is fractured, and a half-inch or one inch shortening occurs, the two limbs when examined by the surgeon will measure exactly the same, and no evidence will be derivable from such attempts at estimation of shortening. If the shorter limb is subjected to traumatism, shortening may seem to exist when such is not the case; or the traumatic diminution in length which actually exists will appear to be greater than it is. Fortunately the normal difference of length rarely exceeds a quarter- or half-inch. . The most practical method of measuring the length of the limbs is to carry a tape measure from the lower edge of each anterior superior Spinº of the ilium to the tip of the corresponding internal malleolus. It is well, perhaps, to verify the differential measurement by placing the upper end of the tape at the lower margin of the umbilicus, and holding it theº while the lower end is successively carried to the two internal malleoli. During the measuring the pelvis must be horizontal—that is, at a right angle with the median line of the body—and the two limbs in the Saº condition of abduction and extension. The difficulty of obtaining exactly F. R A C T U R ES OF T H E FE M U R . 421 the same point of measurement on the two sides, because of the mobility of the skin and the want of definite outline in the prominences, together with the fallacy above mentioned, have made me place little confidence in the accurate estimation of fracture shortening. The determination of the relative position of the two greater trochanters by means of Nélaton's line or Bryant's rectangle is of great value in proving elevation or absence of eleva- tion of the trochanter on the injured FIG. 234. side. The method is useful in sup- posed dislocations as well as fractures, but will be discussed here. Nélaton's test line is applied by carrying a string % tº t #º §: § SSS § § tº WN Nº £º-Essº - from the tip of the anterior superior * sº §§§ e f the ilium to the tip of the *4% Yº º spine o tº © p © &#% ($ N ăş sº º tuberosity of the ischium.

Displacement kº Mºsséſ; of the trochanter upward, from short- §§Nº. ening due to cervical fracture, and dis- placement downward or upward, as a result of dislocation, are indicated by comparing the two hips. The two limbs must be examined when neither abducted nor adducted, since in normal limbs the former position brings the trochanter above the line and the latter below it. Bryant's rectangle consists Nélaton's line, dark. Bryant's rect- of two lines drawn while the patient angle, dotted. (ERICHSEN.) lies upon his back. A vertical line is dropped from the anterior superior spine of the ilium to the bed; toward this line, at a right angle to it, a second line is drawn from the upper border of the trochanter. The last drawn line determines the fact and degree of elevation of the trochanter as compared with the sound side. The fallacy due to abduction or adduction must be remembered here, as in using Nélaton's line. Stimson uses Bryant's method by placing a small stick or pencil verti- cally against the pelvis in a line with the process and tuberosity, and meas- \ring from it to the trochanter. Morris estimates changes in distance between the joint and the trochanter by measuring from the outer surface of the trochanter on each side to the median line of the body. This is Readily done by means of a graduated rod placed across the pelvis at the lºvel of the two anterior superior lines of the ilium, with its centre over the linea alba, and having upon each end a sliding vertical bar, which °ºn be moved till it just touches the outside of the corresponding tro- chanter. These are the simplest and most available plans for determining shºrtening of the neck or displacement of the trochanter. More compli- *dgeometrical methods introduce more sources of possible error. ...Allis has called attention to relaxation of the fascia lata between the iliac crest and trochanter, and above the outer condyle of the femur in fractures accompanied by shortening. Cleeman has directed the profes- ** ſo ºbserve a wrinkle in the skin over the ligament of the patella, which will be obliterated when the shortening is corrected by extension. 422 I) I S E A S E S A N D IN J U R IES OF B O N E S. If shortening has been detected, its correction may be attempted for diag- nostic and therapeutic purposes by gentle traction and slight internal rota- tion. Marked rotary movements, IFIG. 235. however, and absence of support to the limb are liable to cause sepa- ration of fragments which may be impacted, and should therefore be avoided. The shortening corrected by traction will usually recur when the traction is intermitted, and thus confirm the diagnosis of fracture. Crepitation is a symptom of cer- vical fractures of great diagnostic value when elicited, but is often unobtainable. It should seldom be sought for with avidity be- cause of the risk of separating im- pacted fragments. Pressure behind the trochanter or traction, with or without rotation, will often make it evident; but impaction, great splintering, wide separation of the fractured surfaces, or the impossi- bility of keeping the small upper i. fragment steady in the acetabulum, ! often prevents its production. Cases \\ showing from other symptoms un- %d. doubted evidence of fracture should º i. not be submitted to persistent ma- t mipulation for the production of cre- | pitus. In obscure cases its develop- ment will not usually afford evidence Allis's method of testing relation of fascia of sufficient value to warrant the lata. risk of detaching impacted frag- ments. Rubbing of the outer frag- ment or of a dislocated head upon the ilium sometimes simulates crepitus between two broken surfaces. The character of the grating is softer than in fracture crepitus. Crepitus is more frequently detected with ease in fracture of the base of the neck than in those of the constriction of the neck, especially if the fracture line runs into the trochanter. * The other symptoms liable to be found in cervical fractures are pain referred to the trochanter, groin, or thigh, tenderness on pressure in the groin outside the femoral vessels, swelling or diminished depressibility at the upper part of thigh, ecchymosis appearing only after two or three days have elapsed, spasm of muscles, flattening in the trochanterić region, or enlargement of the trochanter due to splitting or comminution. The outer surface of the trochanter may be further than normal from the middle line of the body, nearer to it, or may present no change in this respect, according as angular deformity, crushing, and separation exist alone or are combined. Morris's method of investigating this symptom has been discussed. It is evident that, if the normal limb is rotated, the trochanter must move in the are of a circle whose radius is the distance between the articular surface of the head and the outer surface of the trochanter; F. R A C T U R E S OF T H E FE M U R . 423 but, when the neck is broken and unimpacted, such rotation will be in the arc of a circle whose radius is the distance from the line of fracture to the trochanteric surface. The second radius will be shorter, and hence the arc of rotation traversed by the trochanter more curved. Such change may be estimated by placing the hand on the outside of the trochanter while an assistant rotates the limb. This test has often been recommended as worthy of diagnostic credence, but it has at my hands been of little service. If thickening of the soft parts and a large amount of callus is detected in the groin, or about the trochanter at the end of one or two weeks, fracture of the base of the neck is of course the prob- able lesion. DIAGNOSIS.—The diagnosis that fracture of the neck of the femur exists can usually be made with comparative ease, but whether the lesion is at the constriction or at the base of the neck is a problem much more difficult to solve. It is not a question worth attempting to answer, except in those cases where it is almost self-evident. The treatment of both injuries is the same, the elaborate tables of supposed diagnostic differences between fractures of the constriction and of the base have been proved unreliable, and the endeavor to make an accurate diagnosis is fraught with great danger to the future usefulness of the limb by reason of breaking up impaction and severing untorn periosteal attachments. When there is doubt as to the kind of fracture, or as to whether fracture, contusion, or sprain exists, always treat the lesion as fracture of the base of the . and the result will clear up the doubts in the course of a few WeekS. The symptoms which have just been discussed at length will, when taken in connection with the history of a fall and the non-existence of any former arthritis, fracture, or other pathological conditions, seldom fail to indicate that fracture of some portion of the neck has occurred. The differential diagnosis of fractures of the neck and dislocations of the head of the bone is important. Inversion is so rare in fracture that its existence should at once suggest posterior dislocation. Fracture with inversion would not show a flexed, adducted, and such a fixed hip as the posterior luxations; nor would the presence of the head of the bone over the iliac dorsum or sciatic notch, and its absence from the acetabular region be demonstrable. In fracture with inversion, traction may convert the inversion into eversion and correct the shortening, but not so in dis- lºcation. The anterior dislocations are rare injuries; present flattening of the trochanteric region, abduction, and flexion of the hip, and the unusual fulness or prominence at the abnormal site of the head of the bone. The pubic dislocation is accompanied by shortening, the thyroid not by shortening but by apparent lengthening. In dislocation there is a marked limitation of passive motion, and the limit of possible mobility is reached by a sort of sudden stopping or check felt by the surgeon’s hands. In a normal femur the inner condyle and the head of the bone always have the same direction: therefore, the position of the head can be determined in dislocations by observing the direction of the inner condyle. This is *9t true of fractures of the femur. If there is anterior spinal curvature the hip may be somewhat flexed, and still appear extended. This pos- sible source of error is eliminated by placing the man on his back and flexing the opposite thigh completely on the abdomen, when the second thigh Will be raised from the bed, if it be in a state of flexion concealed by the spinal curve. 424 DIS E A SES A N D IN J U R IES OF B.O N ES. PROGNOSIS.—Patients with fractures of the femoral neck have died not infrequently from rapid debility, severe arthritis, or other inflammation about the injury, or hypostatic pneumonia. Especially has this been the case in the aged. The unfortunate tendency was possibly dependent in some measure upon fat embolism, but more probably upon the rigid confinement to bed with cumbersome and uncomfortable fracture dressings, which used to be enforced for long periods. Our present methods of treatment with continuous traction and less absolute immobility in bed seem to permit a much better prognosis. The unfavorable outlook so often spoken of in hip fractures is possibly scarcely warranted by our present experience. A certain amount of shortening, eversion, stiffness, and pain often persists even in fractures that have recovered with fibrous or osseous Runion; but fair, or even very good, use of the limb is not unusual, even in old persons who have apparently or certainly sustained fracture of the constriction of the neck. Even when the fracture remains ununited fair walking is possible, because hypertrophied muscular and tendinous bands may support the pelvis as by a sling attached to the greater trochanter. TREATMENT.—In treating fractures of the lower extremity, the firm, level mattress is much more important than in similar lesions of the upper limb. A plain mattress made of hair, and a bed-pan for receiving the dejections, is often preferable to any one of the various forms of fracture bed sold by manufacturers. Careful nursing will prevent injurious move- ment during the use of the bed-pan. Union is to be sought in all cases of cervical fracture, and its acceptance even in faulty position is more jº. than the production of non-union or violent arthritis in the aged, y reason of vigorous and repeated manipulation, for the purpose of establishing the exact line of fracture or obtaining accurate coaptation. If the existence of dislocation is eliminated, all doubtful cases should be treated as fractures of the base of the neck. Continuous extension or traction, applied by means of a rubber band or weight attached to the leg with adhesive plaster and lateral support to the limb by means of Sand- bags, as employed in fractures of the shaft of the femur, is the proper treatment for all fractures of the neck of the bone. The trochanter may be supported by a small pad or sand-bag placed under it. This method of immobilization is to be kept up until consolidation of the fracture takes place. Proof that union will not occur, or satisfactory evidence that the injury was a mere sprain or contusion, indicate its discontinuance. It must also be discontinued if it becomes evident that the patient's life is endangered by the confinement to bed and to one posture. Then, attempts at gaining union may have to be discontinued in order to prevent death from failure of the vital forces. Even when no union occurs, comfort is usually gained by the rest given to the joint and limb for two or three weeks by traction. Union, when it occurs, takes place in from five to six weeks. The extending force should equal about six to eight pounds, while the counter-extension is to be gained by elevating the foot of the bed about six inches, so as to use the weight of the patient's trunk as a counter-force: The foot should be maintained in a position with the toes pointing upward and a little outward, which is the normal posture of the limb when a man lies on his back. Catheterization will be necessary in many patients, and the occurrence of sacral bedsores must be averted by watchfulness an cleanliness. In order to get more complete immobility at the seat of fracture, the pelvis and both thighs may be encased in gypsum bandages. In addition, FRACT U R ES OF THE SH A FT OF THE FE MU R. 425 a pad adjusted by a screw, passing through a frame attached to the gypsum dressing, may be arranged to make pressure upon the outside of the tro- chanter, and thereby hold the fragments in apposition. This is the char- acter of Senn's method. Gunshot fractures of the femoral neck will require provision for free drainage, and perhaps excision of the head of the bone. Attempts to fasten the capital fragment to the trochanteric one by Screws and pegs have been made in the endeavor to avoid non-union, but at the present time such attempts seem scarcely warrantable. Fractures of the Shaft of the Femur. Fractures of the shaft of the femur include those occurring in the shaft of the bone anywhere except just above the condyles. The latter, being near the knee-joint and liable to special complications, are discussed under Fractures at the Lower End of the Femur. Transverse fracture of the shaft is not rare in children, but in adults such an occurrence is very unusual. In fractures of the femoral shaft, deformity due to over- riding and to angular or rotary displacement is apt to be great. When the fracture is in the upper third, the lower end of the upper fragment is generally tilted outward and forward by the great psoas, iliac, and ex- ternal rotator muscles of the hip, and the upper end of the lower fragment drawn upward and inward by the flexors of the leg and adductors of the thigh. This special angular distortion is mentioned because it at times compels the adoption of unusual methods of treatment. SYMPTOMs.-The symptoms indicative of fracture of the femoral shaft are: total loss of voluntary power in the limb, eversion of the foot and leg, and the usual concomitants of fractures, deformity, abnormal mobility, and crepitus. Rotation of the limb is not accompanied by movement of the greater trochanter. The deformity and flexibility of the thigh at the seat of fracture are often entirely sufficient for diagnosis without requir- ing successive attempts at getting crepitus, which cause pain and may do harm. The shortening, which is chiefly due to the powerful muscles sur- rounding the broken bone and to the obliquity of the fracture, may be Very great, but is overcome partially, if not entirely, during the continu- ance of strong traction. The estimation of the degree of shortening by measuring is, as has been mentioned under Eractures Near the Hip, sub- ject to fallacies. The symptoms may be a good deal modified by impac- tion or interlocking of fragments. This condition, however, is unusual. Union occurs in ordinary cases in about six weeks, after which time the patient may be trusted to use crutches, provided that all possible Strains upon the repaired fracture are avoided by suitable supporting ºsings, and that no weight is borne on the injured limb in walking Pälsion into the knee-joint often occurs after the fracture, sometimes Within a few days, and occasionally it persists for many months. It has been attributed to involvement of the synovial membrane; to invasion of the joint by the blood extravasated at the time of fracture; to coincident *Pºin of the knee; to interference with venous return, and to the posture and prolonged immobility of treatment. Fractures at the lower third should be expected to present this complication most frequently. It needs, as a rule, no special treatment. tl sº Permanent shortening is to be expected after every fracture of **mur; but, if union is obtained with the fragments in good line, 426 D IS E A SES AN ID IN J U R IES OF B O N E S. without rotary displacement, a shortening of even three-quarters of an inch will cause little limp in the gait. Rigidity of the knee may remain for a long time in rheumatic or aged patients. Open fractures of the femur, especially if also comminuted, are rather dangerous lesions, requir. ing, in even favorable cases, a protracted convalescence. In all fractures of the femur, with rare exceptions, permanent horizontal traction, or extension, as it is often called, by means of adhesive plaster and attached weights, is the best method of treatment. Counter-extension is to be obtained by elevating the foot of the bed six inches. This pro- cedure makes the weight of the trunk act as a counter-extending force. Any tendency to lateral mobility or deformity of the fragments may be avoided or corrected by short coaptation splints of wood, metal, or paste. board, or by long narrow bags, well, but not too tensely, filled with sand and laid closely along the inner and outer sides of the limb. The outer bag should extend from below the sole to within a few inches of the axilla, the inner bag from below the sole to the perineum. Before the application of the plaster strips the thigh and leg should be shaved. A piece of thin board, three inches wide and five inches long, is FIG. 236. Adhesive plaster and foot-board applied for continuous extension. fastened lengthwise to the middle of the adhesive side of a strip of rubber adhesive plaster three inches wide and six feet long. This stirrup-like apparatus is then smoothly attached to the limb by applying the plaster up the sides of the leg and thigh to a point just below the seat of fracture. Its adherence to the skin is further assured by applying narrow bands of plaster around the limb and side strips at three points—namely, above the knee, below the knee, and about an inch above the ankle. A bandage is next applied over the foot and malleoli under the stirrup, and then carried up the limb over the adhesive plaster attachment until it nearly reaches the height of the fracture. The terminal ends of the plaster which pro- ject above the last fold of the bandage are now turned over the bandage, so that their adhesive surface becomes external. Around these turned down ends the bandage is applied by a few more folds, until no vestige of the plaster is seen. The attachment of the plaster to the skin should extend above the knee, in order to avoid what might prove injurious traction on its ligaments. The turning over of the ends is additional security against the traction weights causing the adhesive strips to slip on the skin. To the foot-piece a cord about three feet long should be attached so that in the course of an hour, when the plaster has become firmly adherent to the skin, the traction weights may be tied to the apparatus. When it is thought that the plaster will bear the weight without slipping, the surgeon props up the foot of the bed, and, taking hold of the foot and ankle, makes powerful but steady traction to overcome the muscular spasm causing the over-riding and shortening. If there is great shortening, F R A CT U R E S OF T H E S H A FT OF T H E FE M U R . 427 or if the patient is very muscular, it may be well to obtain relaxation of . the muscles by producing a slight degree of general anaesthesia with ether or nitrous oxide. When the deformity has been overcome as much as possible, two or three bricks, or an equivalent weight, are tied to the cord and suspended over a pulley at the foot of the bed. The pulley should be placed high enough to lift the heel a little from the mattress, and in such a posi- tion laterally as to keep the axis of the limb cor- rect. The cord should not let the bricks rest on the floor when the patient slides toward the foot of the bed, though it should be long enough to let the patient slide up and down for the distance of a foot or so. There should be no shelf or obstacle above the floor upon which the bricks may catch and suddenly fall off with a jerk. The pulley must have side-pieces or an arch projecting above the groove, that the cord may not be pushed off by persons passing the foot of the bed. Instead of using the adhesive plaster apparatus a series of straps may be adopted. The amount of weight for the first three weeks should be from fifteen to twenty-five pounds for an adult, according to the muscular development and tendency to spasm. At the end of that time the amount may be decreased one-half, and be discon- tinued at about the sixth week. Then a circular gypsum or silicate of sodium dressing is applied from the ankle to the hip, including the pelvis if the fracture is in the upper third, and walking with Crutches is permitted. The patient should not bear any of his weight on the foot till the tenth or elev- enth week. If the gypsum or silicate dressing is not adopted, sufficient lateral support may be ob- ! tained by using coaptation splints of moulded paste- Levis’s pulley for con- board, provided that the knee and hip are fixed by tinuous traction appa- them. It is, of course, understood that the patient ratus. shall, not be permitted to walk even with these dressings, unless the fracture has lost its mobility. Caution must be exerted against subjecting the limb to strains or falls, for rupture of the Gallus readily occurs, even as late as three or four months after the original Injury. Usually a slight amount of padding is required on the bed beneath the Popliteal space, because the absolutely straight position of the knee be- $omes, painful unless a little support is given at the point mentioned. If lateral deviation at the site of facture is not prevented by the sand-bags, * if there is antero-posterior bending, three or four coaptation splints of Wood eight to ten inches long may be applied over the bandage and kept * Place by a few turns of another bandage. Pasteboard or other plastic *ºrial may be moulded to the front or side of the thigh, if the surgeon Prefers. Care must be taken that pressure of the heel on the bed does nºt cause a bedsore. A mass of oakum, wool, or cotton, hollowed out like º bird S nest to receive the heel, or a pad placed beneath the tendon of f º so as to lift the heel from the mattress, are the simplest devices **lieving this injurious pressure, The bed-clothes must not rest on the 428 I) IS E A S E S A N D IN J U R IF. S OF B O N E S. toes, since their weight will press the foot outward and evert the leg. Any sort of an arched frame, such as can be made from pieces of barrel hoop placed over the foot, will hold the coverings up. It is also necessary to see that the patient lies flat on his back, for if he turns a little on his side, or if the pelvis sinks into the mattress on one side, while the foot and leg are held motionless by the dressing, rotary deformity will remain when the fracture is united. The foot should be kept very slightly everted, as has been stated under the treatment of Fractures Near the Hip. The patient should not be allowed to sit up in bed nor have a high pillow or bolster, until at least three weeks have elapsed. Then he may be propped up in the half-sitting posture, if it shows no tendency to displace the partially united fracture. The sliding movements up and down in the bed, which are permissible from the begin- ning, relieve the monotony of confinement very much, and enable the nurse to adjust the bed-pan and keep the patient clean. When, in fractures of the upper third, there is marked tilting forward of the upper fragment, the straight position just described is not always satisfactory. It may become necessary to elevate the lower fragment, in order to meet the displaced upper fragment and preserve the proper axis of the limb. In order to get proper apposition of the fragments the limb with the traction apparatus attached should be elevated upon an inclined !

The weight extension can readily be continued at the same time. Whether the inclined plane is such as will keep the knee straight or flexed is a matter of comparative indifference. FIG. 239. Double inclined plane fracture box. In treating open fractures with much suppuration a long fracture bºx or the anterior wire splint of Nathan R. Smith are often convenient. The method of using the anterior splint is shown in the illustration, except FR A CTU RES OF T H E SH A FT OF THE FE MU R. 429 that the pulley should be placed over the middle of the leg so as to obtain extension or traction by the weight of the buttock. FIG. 240. SN Tº * } Smith’s anterior splint. In infants below five years it is often difficult to prevent soiling of the traction apparatus by the alvine discharges; hence, vertical extension has been employed with good results. This is effected by flexing both hips at a right angle, placing straight splints along the posterior surfaces of the limbs to prevent flexion of the knee, and attaching the feet to a sup- port over the bed. The buttocks thus act as a traction weight and the little patient can be kept clean. If preferred a pulley and a weight of four or five pounds attached to the leg and foot may be used to increase the traction power. When the child is over four or five years of age the ordinary horizontal traction is easily employed. The weight should be about one pound for every year. Union becomes firm in children in about four weeks. - FRACTURES OF THE Low ER END OF THE FEMUR.—These injuries, occuring so near the knee-joint and having a short lower fragment, which may be difficult to control, deserve some special consideration. The line of fracture may be in the shaft just above the condyles, may at the same time run dowward between the condyles, splitting them apart, or may not involve the shaft at all but merely separate one of the condyles or a part of a condyle from the rest of FIG. 24l. the bone. Sometimes small pieces of the bone are º torn up by strains on the crucial ligaments. The last two varieties are very rare. The epiphysis, which includes the entire condy- loid portion of the bone, may be detached in per- sons not over twenty years of age. The line of fractures just above the condyle is usually oblique, but a transverse direction is said to be more com- mon than when the bone is broken at a higher point. The lower fragment in fractures above or through the condyles is frequently displaced back- femoral epiphysis. (Bry- Ward and may, by pressure upon, or laceration of, ANT.) the popliteal vessels, cause gangrene of the leg. * Same result may follow similar displacement of the upper fragment. The usual symptoms of fracture are present. The lateral mobility possible above the knee, the backward displacement of the lower frag- 430 D ISE AS ES A N D IN J U R IES OF B O N E S. ment and the leg, and the prominence and unusual mobility of the patella in supra-condyloid fracture, or its sinking between the separated condyles in inter-condyloid fractures, are additional aids to diagnosis. A pointed upper fragment is sometimes driven into the fibres or tendon of the four- headed extensor muscle or thrust through the integument. Effusion or hemorrhage into the knee-joint is particularly common in fractures in- volving the condyles. Death from suppurative arthritis or gangrene, though not frequent, is a possibility to be remembered in giving a prognosis; and more or less ankylosis of the knee is quite usual, especially when the joint is invaded by the fracture line. The proper treatment is permanent horizonal traction, as in fracture of the shaft, with even greater care to keep the knee-joint immovable. This immobility may be attained by a pasteboard splint adjusted to the back of the joint. The adhesive strips for traction should extend along the limb only as far as the knee. If the straight posture does not maintain the lower fragment in proper position, the knee may be partially flexed by placing a pillow or a double inclined plane under it, or by using a Smith's anterior splint. Severe arthritis is an argument for the com- pletely extended position, since, if ankylosis occurs, a straight knee is more useful than a slightly flexed one. If the distention of the joint with fluid is too great to allow the joint to be completely extended, the fluid may be partially withdrawn with an aseptic aspirator needle. If spasm of the gastrocnemius muscle prevents adjustment of the lower fragment, tenotomy of the tendon of Achilles may be justifiable, to weaken the displacing cause. If the upper fragment is buttonholed and so tightly held in the substance of the extensor tendon that reduction of the fracture is impossible, its liberation by subcutaneous or open section of the muscle is proper. Arthritis, if severe, requires appropriate treat- ment. The formation of pus in the joint is a demand for immediate in- cision under antiseptic measures. Fracture of a single condyle is a very rare injury and, owing to the slight deformity attending it, may be mistaken for a sprain or arthritis of the knee. The integrity of the other condyle and the attachment of the broken piece of bone to the tibia prevent shortening and marked displace- ment. Suppuration of the joint has followed condyloid fracture. The diagnosis is to be made from localized pain and ecchymosis, motion and crepitus. Horizontal traction with care to correct any lateral deviation at the knee is the treatment; though a long fracture box or a posterior splint may do equally well. The joint should be kept immovable for three or four weeks. These fractures, and those in which small splinters of bone are torn off within the joint, resemble in their symptoms Severe sprain, and should receive much the same treatment. Fractures of the Patella. PATHology.—The patella is broken generally by sudden and forcible contraction of the four-headed extensor of the leg, and occasionally by direct violence. The patient usually attributes the fracture to the fall upon the knee; but the fall in most cases is due to the previous giving way of the patella from muscular strain exerted upon it, for it is a sesa- moid bone in the tendon. A slip of the foot occurs, and, as the man tries to save himself from falling, the violent muscular contraction bends the F R A C T U R ES OF T H E P A T E L L A. 431 patella across the condyles and fractures it by the cross-breaking strain, or else tears it asunder simply by the powerful traction upward. A similar result may occur in efforts at kicking or lifting. This usual causa- tion of the fracture is proved, in the history of some cases, by the fact that in falls upon the bent knee the impact is received on the head of the tibia rather than on the patella, and by the further circumstances that the line of fracture is usually transverse, that in fractures known to be caused by direct violence the bone shows vertical, oblique, or comminuted fractures, and that no bruise is seen over the patella in the ordinary CàS6S. The fracture from muscular contraction is usually more or less trans- verse, is situated near the middle of the bone, and is generally repaired by fibrous union. Comminuted and oblique fractures usually unite by bony instead of fibrous tissue. FIG. 242. FIG. 243.

Transverse fracture of Oblique fracture of Bony union of comminuted frac- patella. patella. ture of patella. (GURLT.) The transverse fracture, from muscular action, is so much more common than any other that the subsequent description refers to it, unless other- wise stated. The lower fragment retains its normal position; but the upper one is drawn upward by the muscle and pushed upward by the rapidly occurring intra-articular effusion, until the separation amounts to half an inch or an inch. If the muscular aponeurosis surrounding the bone is greatly torn, the displacement may be much greater; and, on the other hand, if the fibrous envelope is not ruptured, the fragments may remain in contact. Lateral displacement may at times occur, but in any marked degree is not common. Some tilting of the fragments due to the Surgeon's dressing or to the intra-articular effusion is not unusual. The fragments may thus be tilted so that they are in contact at one side, but Separated at the other, or may be so everted that the fractured surfaces are directed in an anterior direction. SYMPTOMS.–The symptoms are a sudden loss of extending power at the knee, often accompanied by a sharp snap at the moment the bone §Wes Way ; pain, difficult progression, though walking is often possible if care is taken to keep the tibia and femur in a straight line and the heel to the ground; a well-marked furrow felt with the finger between the fragments, independent mobility of the upper and lower parts of the one, with crepitus when they are pressed together and moved laterally; *nd swelling of the knee from blood and inflammatory products within the Synovial cavity of the joint and the surrounding structures. The *thritis accompanying the fracture does not give rise to the intense pain 432 D IS E A SES A N D IN J U R IES OF B O N ES, so common in other cases of synovitis of the knee, probably because the tearing open of the joint prevents intra-articular tension. The patient is unable to extend the knee after it has been flexed, or to raise the foot from the surface of the bed upon which he lies. The disability, however, varies, as would be expected, with the amount of laceration of the tendi- mous aponeurosis surrounding the patella. The bone has the vastus mus- cles inserted into its lateral margins and the general aponeurosis spread over its front. Hence, extension of the knee may be accompanied to a limited degree by such untorn attachments, even after fracture of the patella. In vertical and many comminuted fractures the extending power will be interfered with only by reason of pain. The joint-effusion will be absent if the case is seen immediately after the injury. The diagnosis is readily made by palpation and the symptoms above described. Fractures with little or no separation, and traumatic bursitis in which the bursa in front of the patella is filled with blood and inflam- matory products, may need careful consideration before a correct under- standing of the lesion is obtained. It is said that crepitus and the feeling of separated bony fragments may be simulated by blood-clots in the bursa. The filling of the prepatellar bursa with fluid secreted by its own wall, or with synovia entering it from the joint, with which communication is mutually established by means of laceration of the bursa and the cleft in the bone, may prevent accurate determination of the exact line of fracture. After about ten days have elapsed the swelling of the joint decreases, and, if the pieces of bone are in close contact, a short fibrous, in rare cases an Osseous, bond of union is established. The fibrous union is often a long one, even measuring three to four inches, and the separation of the fragments may increase on flexion of the knee if the upper fragment has become adherent to the structures on the front of the thigh. Sometimes the bond of connection is little more than a condensation of the fascial structures, and seems not to partake of the nature of an attempt at repair. Use of a quite well-repaired fracture of the patella has often caused the fibrous union to stretch, and stretching may be greater on one side than on the other. Osseous union occasion- FIG. 245.

R A CTU. R. ES OF THE PA. T E L L A . 433 Such secondary accidents show at times little attempt at union. When the tissues have become rigid and adherent about the seat of fracture, and there still remains some stiffness of the joint, the integument may be torn and the joint laid open at the time the secondary fracture occurs. The open fractures so caused or originally open are, of course, very serious injuries. *. FIG. 247. § §* * |§ f * Ununited fracture of patella, from cast. A severe arthritis may leave a very stiff knee; and, even in ordinary cases, free motion of the limb is not attained for six months or a year. This is partly due to the fear of tearing or stretching the ligamentous union by early attempts at motion, which induces the surgeon and the patient to insist upon protracted wearing of splints and abstinence from strong passive movements. The fear is a well-grounded one. After freedom of flexion and extension of the joint has finally been gained, the disability from fibrous union, even an inch in length, is not very great. The patient may scarcely limp ; though a rapid gait or the ascending and descending of stairs will show his imperfect power of control over the knee. Going down stairs is especially troublesome. Active extension of the joint will pºly be possible only when the limb is put in an almost straight po- Sltil Ol). TREATMENT—In treating fracture of the patella, inflammation of the joint should be moderated and a short bond of union secured. These at least are the objects to be sought. Usually rest is all that is required to effect the first result. Cooling lotions may be employed if the arthritis Prºmises to be severe. When there is very great intra-articular effusion, ºšting as late as ten days or two weeks after the receipt of injury, aspi- ...tion of the joint with an aseptic aspiration needle may be performed. The small size and irregular margins of the fragments, their being imbedded * a tendinous aponeurosis which is attached to the bone at the anterior ºdge of its margins, and the convex surface of the condyles on which the fºgments rest, all make accurate adjustment by encircling dressings difficult and unsatisfactory. - fe The best treatment for the majority of cases is obtained by drawing the *&^ents together by means of steel hooks thrust through the skin and 28 434 D IS E A SES AN ID IN J U R IES OF B O N E S. imbedded in the tendon above and below the upper and lower fragments respectively. The hooks devised by Malgaigne are effective, but on account of the irregular shape of the bone do not permit as accurate co- aptation as do those devised by Levis. These latter are separated pairs and can, therefore, be introduced parallel to each other or at an angle; Varying with the line of fracture and tendency to irregularity in the dis. placement. Each pair of hooks has its points held together, after coap. tation of the fragments, by a screw or by a lateral clamp. FIG. 248. FIG. 249. i Rºs ; zº Levis’s modification of Malgaigne's patella hook. To get rid of the muscular displacing cause the leg should be kept fully extended on the thigh, and the thigh perhaps slightly flexed on the pelvis. This is readily done by elevating the limb on an inclined plane; or by supporting it with pillows after placing any form of rigid splint behind the knee. This position relaxes the three muscular masses arising from the femur and also the rectus, which has its origin from the pelvis. Absolute rest in this position for about a week, with perhaps the applica- tion of cooling lotions, will cause absorption of the articular effusion which aids in separating the fragments. If it does not, aspiration is justifiable. At the end of this time the fragments can usually be pressed together by the surgeon's fingers and held while the hooks are inserted, so as to keep them closely approximated. It is best to put the lower hook of the pair in position first; and then the upper fragment, which is the displaced one, can be controlled by the insertion of the second hook. The points of the hooks must be sharp, and should be thrust as deeply as possible into the tendon close to the margin of the bone. There is no danger of entering the joint, for the tendon is very thick and tough. After one pair has been inserted the other is to be placed where it will best hold the fragments firmly together. The skin should be drawn tightly over the knee-pan before the hooks are inserted, and both the surface of the skin and the hooks cleaned and made aseptic. Ether may be required F. R. A. CT U R ES OF T H E PA. T E I, L.A . 435 in some patients, since the operation is rather painful, though not a tedious one. The points of puncture and the surrounding skin should be dusted with boric acid or iodoform, and the parts surrounded with a dressing of dry antiseptic cotton or gauze. The hooks should be kept in place for six weeks; and, when removed, the patient, though using crutches, should wear a posterior splint for five or six weeks longer, in order not to tear the broken bone asunder by Sud- denly flexing the joint. Sometimes the hooks may need tightening once or twice as the swelling subsides, but usually no change is required. Their removal from the first punctures is not to be expected until they are finally taken out. The irritation produced by the hooks is inconsiderable. If a tendency to erysipelas or abscess about the punctures is feared because of the unhealthy condition of the patient or for any other reason, the hooks should not be applied; or, if already applied, they should be re- moved. Under such circumstances the adhesive plaster dressing is proba- bly as simple and efficient as any. - The adhesive plaster dressing is applied as follows: After the knee has been extended and the entire limb elevated, the middle of a strip of adhe- sive plaster about two feet long is placed on the skin beneath the lower patellar fragment, and its ends carried upward and crossed upon the back of the thigh. By two or more strips applied in a similar manner, but not exactly corresponding with the first, the lower fragment is steadied. Then similar overlying strips are placed above the upper fragment and used to draw it down toward the lower one. The ends are crossed on the back of the calf of the leg. Over the whole a roller bandage is applied from foot to hip, and the limb kept extended and elevated by an inclined plane. Renewal of the adhesive plaster will be required about once a week, during the six weeks that the dressing is used before permitting the patient to be up on crutches. In applying this and similar constricting dressings there is a great tendency to tilt the fragments so that the ante- rior edges of the broken surfaces are further apart than the posterior. Perhaps this may be avoided by one or two strips carried directly around the front of the knee-joint. - For a long time after discarding all apparatus and crutches the patient should support the patella by wearing a knee-cap of elastic webbing. Open fractures of the patella should be treated by free incision into the joint, washing out the synovial sac with a five per cent. solution of carbolic acid, a sublimate solution (1:2000), or beta-naphthol solution (1 : 2500), and free drainage by tubes. If the opening is very small and the injury just received, the attempt to convert the fracture into a glºsed one without free incision may be proper; but the first sign of joint inflammation is a signal for free incision, antiseptic washing, and drainage. The use of the hooks or the adoption of a simple posterior splint to main- tain the extended position will necessarily be the treatment in all such $ºses, since the adhesive plaster dressing and similar devices can scarcely * ºpplied The drainage-tube need not, as a rule, be retained over a Wee • Rupture of the bond of union or refracture of the patella should be *ated as the original fracture.

The treatment, as well as the Symptoms, is similar. The treatment of fractured patella by wiring the fragments, and the *gement of cases with long fibrous union by resection and wiring are 436 I) IS E A S E S A N D IN J U R I ES OF B O N ES. not justifiable. The disability resulting from imperfect connection of the fragments is not great enough to warrant the additional though slight risk to life assumed. Such, at least, is my opinion. I am prepared to have the fracture in my own person treated by the hooks, but not by wiring. Therefore, I recommend one and condemn the other. Fractures of the Tibia and Fibula. The tibia and fibula are each developed by three ossific centres, one for the shaft and one for each extremity. The upper epiphyses unite at about twenty-five years of age, the lower at about twenty years. Occasionally the tubercle and malleolus of the tibia develop from separate centres. The possibility of epiphyseal separations occurring when the bones of the legs are subjected to violence should be recollected. Such diastases are, however, very rare. t FRACTURES NEAR THE KNEE.–Fractures at the upper end of the tibia, which usually are accompanied by fibular fracture, are frequently transverse, and may, by more or less vertical lines, invade the knee-joint. If the fibula is neither broken nor dislocated, it aids in preventing dis- placement. Epiphyseal separation here, as elsewhere, is liable to inter- fere with growth of the bone in length. Hence the uninjured fibula as it grows must either become bowed or dislocated at one of its ends. The usual symptoms of fracture may be associated with those of syno- vitis of the knee, or of injury to popliteal vessels and nerves. The prog- nosis is serious because of the possibility of ankylosis, suppurative arthritis, and other complications. The fibula is seldom broken at its upper end, except when the tibia also is fractured. FRACTURES OF THE SHAFT OF THE TIBIA AND FIBULA. PATHOL- oGY.—The tibia alone is seldom broken except when the fracture is due to direct violence, such as a kick on the shin. The line of fracture is then apt to be somewhat transverse. The fibula, being the smaller bone, may readily be broken while the tibia remains intact. If both bones are involved, the fibula is likely to give way at a higher point than the tibia. The most common point of fracture of the bones of the leg is near the junction of the middle and lower thirds, and a frequent displacement is projection of the upper fragment forward and inward while the lower fragment is drawn upward, behind the upper fragment, by the great muscles of the calf. The subcutaneous situation of the tibia makes per- foration of the integument and the conversion of the fracture into an open one quite frequent. SYMPTOMS.–The symptoms of fracture are easily discernible, especially when both bones are broken, since mobility and deformity are then pres: ent to a greater extent than under the opposite condition. The tibial crest and inner surface are so easily felt through the thin overlaying tis- sues that deviation in outlines here can scarcely be missed unless sufficient time has elapsed for the development of the great swelling which so often happens. Patients have occasionally the ability to walk upon a broken tibia, and even when both bones are fractured such a feat is not impossible. Walking after fracture of the fragile fibula is neither surprising nor uncommon. If it has been ascertained that the tibia is broken, fracture of the fibula may usually be assumed, unless the history is that of an injury of a localized character received in the tibial region. If the fact is not evident from the general deformity and preternatural mobility of F. R A CTU. R. ES OF THE TIBIA. A N D FIBU L A. 437 the limb, pressure along the fibula may perhaps elicit pain, crepitus, or yielding sufficient to establish the fact of its fracture. When such evidence is not at once obtained, repeated and vigorous attempts at developing symptoms of fracture of the fibula are not wise or justifiable, unless the treatment is to be influenced by such knowledge, which is rarely the case. The formation of blebs on the surface of the leg, great swelling, violent cellulitis, and fat embolism are not unusual accompaniments of the severe injuries that give rise to fractures of the leg bones. Union in uncomplicated cases of tibial fracture is firm in five or six weeks; in fibular fracture in from three to four. The bridge of callus occasionally uniting the bones after cure is of no evil consequence, since rotation is not a function of the leg and foot, as it is in the upper extrem- ity. Non-union is not so very infrequent, and when occurring is probably often occasioned by imperfect immobilization due to faulty dressings. Comminuted and very oblique fractures require more time for consolida- tion. Neuralgic and rheumatic pains, persistent oadema, rigidity of the ankle, and chronic ulcers from defective restoration of circulation are not unusual sequences of fractures in the leg. FRACTURES OF THE TIBIA AND FIBULA NEAR THE ANKLE. PATHOLOGY..—These injuries are frequent and often very serious injuries FIG. 250. FIG. 251. 2 ! ( \ w \ Vertical section of bones at ankle- joint. (TILLAUX.) Both bones. may be broken without complication, they may be greatly shattered with the ankle-joint involved, the fibula alone may be fractured, Deformity after a bad fracture at the ankle.

The lower end of the tibia is scarcely ever broken without the fibula being similarly injured, though the fracture of the latter bone may be two or three inches above its tip. In making this statement I refer to the base of the tibia and not to its malleolus, which can readily be chipped off without the fibula sustaining any fracture. On account of the mortise-like manner in which the astragalus fits between the malleoli, lateral mobility of the normal ankle-joint is impos- sible, though it is simulated during the extended position of the foot by the slight rotation about a vertical axis which is possible. Lateral motion between the tarsal bones is sometimes mistaken for lateral movement in the ankle-joint. The impossibility of other motions than flexion and extension renders the occurrence of bad fractures common when falls, twists, or direct violence tend to forcibly evert or invert the foot at the ankle-joint. By such mechanism one bone may be fractured, or one malleolus may be torn off by avulsion through the lateral ligament; while the other is broken from the shaft by the astragalus within the joint being driven against its inner surface. Instead of involving the malleoli only, the force may fracture the tibia and fibula above the malleoli, rupture the ligaments holding the lower ends of these two bones together, and even so displace the foot laterally as to drive one of the bones through the skin. The dissolution of integrity of the inferior tibio-fibular ligamentous bond allows, by widening the mortise in which the astragalus lies, lateral mobility in the joint, and suggests severe damage to the articulation, unless examination shows that the line of fracture has been limited to one of the malleoli or to the fibula above its malleolar extremity. Occa- sionally the astragalus has been actually driven up between the tibia and fibula. FIG. 252. FIG. 253. Diagram showing frequent fracture-lines Fracture of tibia and fibula at ankle. from forcible eversion and abduction of foot. (GRoss.) (STIMson.) SYMPTOMs.-The symptoms in the majority of cases are characteristić of fracture, though occasionally it is necessary to examine the malleoli and fibula carefully in order to avoid calling the injury a sprain. Local- ized tenderness and ecchymosis will often be determining symptoms in obscure fracture of these parts. “Sprain-fracture,” or sprain with detach- ment of a small piece of bone from the end of the malleolus, is not un- F. R A CT U R ES OF THE TIB I A. A. N. D F IBU L.A . 439 common at the inner malleolus. The fracture of the fibula may be two and a half inches above its tip. # In the form of injury depicted in Fig. 253, which is quite common, the foot is displaced to the outer side, the inner malleolus prominent, the sole of the foot everted, and the heel apparently elongated. There is sometimes a groove on the outside of the ankle at the point where the fibula has given way. Pain and ecchymosis will probably be found in both malleolar regions, and lateral mobility at the ankle-joint will be detected if the calcaneum and astragalus are seized with one hand while the lower end of the leg is grasped with the other. Motion in the tarsal joints must not be mistaken for ankle motion. Fracture of the lower part of the fibula can often be detected by placing the fingers behind the upper third of its shaft and endeavoring to lift it forward. If this causes pain about the lower portion of the bone, it is evident that the fibula is fractured and movable at the point of pain. This test has often been very serviceable to me in obscure injuries about the ankle. * Uncomplicated fractures about the ankle, without much displacement or with easily corrected displacement, give good results and do not leave any very great final stiffness. The period of union is about five weeks, but it requires many weeks to restore the mobility of the ankle. Where there is great deformity and the eversion or inversion of the foot cannot be overcome, permanent disability results from the weight of the body being carried on a foot out of proper line. The strain on ligaments and bones in the unusual relations creates lameness and a tendency to increased deviation from the normal axis. Open fractures in which suppuration occurs are of serious prognosis, because, when restitution of position is made, the external wound frequently does not correspond with the point of fracture, and decomposing secretions are retained. Free incisions and the introduction of drainage-tubes may not only avert amputation but save life. Ankylosis is common in bad fractures entering the joint. Such fractures, especially, should be treated with the foot at a right angle to the leg. &º 3.3% ſºº º Method of adjusting the leg in fracture-box. *ATMENT-There are few fractures of the bones of the leg that cannot be properly treated in a fracture-box, with hinged sides and foot- i. and appropriate compresses.

The next step is to raise the sides of the box, by which means the edges of the pillow are pressed against the broken limb, and to hold them in position by pieces of bandage drawn underneath the box and tied over the top. The amount of pressure exerted by the sides of the box, which act as lateral splints, call F R A CT U R ES OF THE TI BIA AND FIBU L.A. 441 be regulated or changed by tightening or loosening the encircling strips of bandage or altering the thickness of the pillow. If any lateral deviation in the line of the leg is observed by running the finger-tip along the crest of the tibia, it can be corrected by compresses slipped between the sides of the box and the pillow at the appropriate places. Anterior or posterior displacement can usually be overcome by elevating or depressing the heel, which is done by increasing or diminishing the size of the ring used to prevent a bedsore on its tip. F1 G. 257 Elevated fracture-box. (STIMsoN.) No primary bandage should ever be applied to the leg from the toes to the knee, as the danger of gangrene produced thereby is too great. In suspending the fracture-box, which should always be done except in some fractures close to the knee-joint, and in those which require horizontal traction from the foot, cords should pass through openings in the upper part of the sides of the box and be attached to a single cord carried to a pulley fastened above the bed. It is easy to devise methods by which the height of the box from the bed may be changed to suit the patient. The posterior end of the box must not be allowed to drag on the bed, nor should any position be assumed which tends to permit motion or displace- ment at the site of fracture. Rotary displacement is a particularly un- fortunate deformity, as permanent inversion or eversion of the toes is unsightly and interferes with walking. The surgeon should see to it that the ball of the great toe, the inner malleolus, and the inner condyle of the femur are in the same vertical plane, or that the great toe is on a line With the inner edge of the malleolus. When muscular contraction pre- Vents complete reduction at the first dressing, flexing the knee and ex- tending the foot will relax the calf muscles. Stimson says that compres- Sion of the femoral artery for a few minutes has induced for him relaxation of the muscular spasm. Subcutaneous section of the tendon of Achilles is rarely necessary. When the fracture is at the upper part of the leg the knee must be kept immovable; hence the fracture-box should extend above the knee, Which is to be kept straight or slightly flexed, according as one or other Posture favors accurate adjustment of the fragments. If flexion is neces- *Y, a double inclined fracture-box like that used occasionally for frac- 442 DISE A S E S A N D IN J U R IES OF B O N E S. tured femur may be needed. It is not easy to suspend this form of box, nor is it necessary; but, with the knee in a straight box, suspension is readily accomplished. The synovitis, often complicating, should be watched, and if purulent must be treated by incisions, antisepsis, and drainage. In very oblique fractures of the shaft continuous longitudinal traction may be needed to correct the over-riding. This can be attained by ele- vating the foot of the bed as in femoral fractures and attaching a weight to the footboard of the box, after placing under the box a smooth board or kind of railroad upon which it can slide up and down. Another method is to apply a stirrup to the leg, as in fractures of the femur, but by means of shorter adhesive strips, and to substitute for the fracture-box lateral coaptation splints or sand-bags. When the fracture is too low to give sufficient attachment for the plaster, a thin board may be cut in the shape of the sole and attached to the foot by strips of plaster. To this footpiece or sandal, cord and weight can be fixed, and the lateral splints then applied to the leg. When the fibula alone is broken, when one of the malleoli is split off, and even when the tibia itself is fractured, if the line is transverse and the fibula intact, little support is needed. Hence the fracture-box may be discontinued in a week, and the patient allowed to go on crutches with the circular gypsum dressing. This should be worn for about three weeks. In those cases of severe fracture at the ankle in which the foot is greatly everted or inverted, it is of primary importance that the correct axis of the foot should be regained. Hence it is necessary to over-correct the deformity by inverting the everted foot, or everting the inverted foot, and keeping it so till some degree of consolidation has occurred, This being neglected will permit union to occur without reëstablishing the close mor- tise between the malleoli in which the astragalus fits, and thereby will leave a want of solidity at the ankle. The projection backward of the heel must also be corrected by elevating it in the fracture-box. Back: ward displacements can sometimes be well corrected by passing a piece of adhesive plaster under the heel or ankle with its adhesive side against the skin and tacking its ends to the upper and outer part of the sides of the box. The fracture-box, with the judicious use of compresses and the other adjuvants mentioned previously, will accomplish these indications as well, if not better, than more complicated dressings. In many fractures the great swelling will for some days permit the sides of the box to be only partially closed, hence the strips of bandage will need tightening frequently. The box should at first be opened and the leg examined once or twice daily. Afterward it may remain undisturbed for a week, if no burning of the heel or discomfort suggests bedsores or displacement. The blebs frequently seen on the surface, even if contain- ing bloody serum, are of no importance as a rule, and need no treatment. If large, they may be evacuated with a sterile needle and afterward be covered with powdered boric acid. They soon dry up. They are, per- haps, due at times to the unnecessary swathing of the broken limb in lead-water and laudanum, or similar lotions, which are often employed immediately after the fracture. Such applications are often used with the idea of lessening the inflammation, but their virtue in moderating the deep inflammation existing is problematical. Time is the element re- uired. At the end of a week in uncomplicated fractures and after the lapse of F. R A CT U R ES OF THE TI BIA. A. N. D FIBU L A. 443 from three to five weeks in more serious cases, the box should be discarded and the circular gypsum dressing applied from the base of the toes to the knee or above it. The patient can then go about on crutches. When the fracture is at the ankle the dressing should be made additionally firm there by extra turns of the bandage. The foot should in such cases be held in the correct position for from fifteen to thirty minutes, till the gyp- sum sets firmly. Care must be observed in order that the tarsus itself may be pressed over, and not merely the anterior part of the foot. The gypsum cast should be worn about three weeks in all cases. Open fractures, not demanding immediate amputation, are well treated in a fracture box after being made thoroughly aseptic and being Sur- rounded by a large gauze dressing. Drainage must be well arranged, even if additional incisions are needed for the purpose. Free drainage and frequent irrigations are demanded if the fracture cannot be converted into an aseptic wound. When union has become pretty firm, or earlier FIG. 258. r ====<=== + :* | | YS$$$. - ==- - “sº Nº. ñº º º Nº.

(HAMILTON.) if profuse discharge has ceased, a fenestrated gypsum dressing may be Substituted for the fracture-box. The device of Van Wagenen, described by Hamilton, is especially nice for suspending such gypsum dressings, and it allows the patient to turn on his side and slide up and down in bed. Crutches are allowed when the fracture becomes firm. Fractures of the fibula have been discussed with those of the tibia; hence little further need be said. Injury of the peroneal nerve is some- ºmes an accompaniment of fibular fracture, and is shown by paralysis. Localized pain and crepitus, and pain felt at the seat of tenderness when the upper part of the shaft is lifted as previously described, are diagnostic symptoms, but are not always present. When the fracture is low down and accompanied by spreading apart of the malleoli, lateral motion of the *agalus becomes possible. The upper end of the fibula has occasionally been broken from the shaft by violent contraction of the biceps muscle. * such cases flexion of the knee to relax the muscle will be a judicious measure during treatment. Union after fibular fracture occurs in three i. #. Weeks. When the fibula alone is broken the fracture-box can § ºpensed with in a day or two and the gypsum dressing applied. In * cases nothing more than a bandage is needed from the first. 444 L) IS E A S E S A N ID IN J U R IBS OF BO N E S. Fracture of the Bones of the Foot. These lesions are usually the result of severe violence, which is often direct; hence many cases present, in addition to the fracture, great damage to the soft parts. Comminuted and open fractures are, there. fore, common ; and amputation or excision of bone often required. Very little apparatus is, as a rule, sufficient to immobilize fractures of the foot, because the size and shape of the bones and the manner of mutual articulation does not favor a wide range of displacing motion, Union is to be expected in uncomplicated cases in three or four weeks, but ankylosis, caries, necrosis and prolonged disability often follow lesions of comparatively slight significance. FRACTURES OF THE TARSAL BONES.—The astragalus and calcaneum are the only tarsal bones whose fractures require special discussion, as fracture of the astragalus is not infrequently associated with dislocation of the ankle and fracture of the fibula, or with calcaneal fracture. Marked displacement is not very common when the bone injury is unaccompanied by a wound leading to the seat of fracture. The diagnosis is difficult, because the crepitus, the inability to bear the weight of the trunk on the foot, the pain and swelling, may be due to fracture of the calcaneum or other tarsal bones. The treatment consists in reducing any apparent displacement and immobilizing the ankle and foot by a fracture-box or circular gypsum dressing. The foot should be at a right angle to the leg, and its sole neither everted nor inverted. In closed fractures, with extreme displacement of fragments, which cannot be overcome and which threaten, by tension on the integument, to produce ulceration, excision of the fragment may be performed at once under antiseptic methods. In open fractures free incisions, counter-openings, drainage and anti- septics are essential elements of success. Febrile reaction and pain are often the surest indications that putrescent fluids are imprisoned. The best point for incision is probably between the extensor tendons of the great and second toes. Ankylosis will result, and hence the foot must be kept at a right angle to the leg during treatment. The body of the cal- caneum may be broken by falls, the sustentaculum tali snapped off by forced inversion of the foot, and the posterior portion of the calcaneum, where the tendon of Achilles is inserted, pulled off by the calf muscles, Flatness of the sole, increased breadth of the foot in the calcaneal region, approximation of the sole to the malleoli, and the limitation of crepitus, pain and motion to the known location of the calcaneum are the distin- guishing features of these lesions, which are often obscure in diagnosis. Fracture of the ledge of bone on the inner and upper aspect, called the sustentaculum tali, is said to allow sinking of the inner malleolus and eversion of the foot, and to be attended by shortening of the heel, as shown by measuring around the back of the heel from one malleolus to the other. When the posterior part of the os calcis is detached by muscular contracº tion, the small fragment may be displaced upward two or three inches. The treatment comprises immobilization in a fracture-box or circular gypt sum dressing; with care to obtain correct position of the foot when the sustentaculum tali has been broken, by moderate inversion. In muscular fracture of the point of the heel, flexion of the knee and extension of the ankle will usually be required to keep the fragment down in contact with the rest of the bone. A slipper attached by a cord to a band around the lower third of the thigh will accomplish this. If preferred, an anterior F R A CT U R E OF T H E B O N E S OF THE FOOT. 445 splint may be moulded to the anterior surface of the limb and the dorsum of the extended foot. Occasionally the force received tears out a little scale of bone at the point of attachment of one of the ligaments. The astragalus is subject to this lesion, which may be termed a “sprain-fracture,” on its posterior aspect, where the external lateral ligament is attached near the groove for the long flexor tendon of the great toe. A similar lesion may occur at the point where the external ligament is attached to the calcaneum. The metatarsal bones most often broken are those of the great toe, really by development a phalanx, and that belonging to the little toe. Metatarsal fractures show little deformity unless several contiguous bones are broken. Displacement, when it occurs, is apt to cause an angular projection on the dorsum of the foot. Pressure of a toe backward toward the tarsus will often, after injury, reveal fracture of the corresponding metatarsal bone by giving rise to pain at the suspicious spot. Immobili- zation by a circular gypsum dressing applied at once, or by a fracture- box, soon followed by the gypsum dressing, is the proper treatment. Open fractures and burrowing of pus must be met by drainage and anti- septics. If the deformity in either closed or open fractures is irreducible and of a character to produce lameness or to interfere with wearing a shoe, excision of the projecting portion of bone is justifiable. Fractures of the phalanges are often compound, and in such cases immediate amputation may be done more frequently than in correspond- ing injuries of the fingers, because the deformity and disability is not as important in the foot as in the hand. The toe in other cases may be made immovable by strips of adhesive plaster holding it to the adjoining toe, by a gypsum dressing, or by a small pasteboard splint bound to the top of the foot and back of the toe by adhesive plaster. Serious inflam- mation not infrequently starts from these insignificant fractures. C H A P T E R XV III. SURGICAL DISEASES OF THE JOINTS, CARTILAGES AND LIGAMENTS. CONG ENITAL DEFORMITIES OF JOINTS (CONGENITAL DISLOCATIONs). THESE deformities arise either from intra-uterine traumata or from nervous or other causes, which may arrest development in portions of the embryo. Fortunately, they are of rare occurrence, taking place prin- cipally at the hip; although the jaw, shoulder, knee and almost any joint may be affected. They are frequently found associated with such other congenital defects as club-foot, spina bifida, exstrophy of the bladder, ventral hernia or encephalocele. FIG. 259.

Double congenital dislocation of hip. (KRöNLEIN.) (STIMSoN.) Treatment of these dislocations is apt to prove unsatisfactory. Reduc- tion should always be attempted, but very rarely, if ever, will the effort be crowned with success, as the joint is more or less defective in construc- tion or portions may be entirely absent. Most usually merely rudimen- tary elements of a joint exist; when palliative measures alone are SY NO WIT I S. 447 permissible. All means calculated to aid in the formation of a false joint should be employed, even to dividing contracted or constricting tissues, or the neck of the femur. In case of the hip-joint an apparatus com- bining a tight band around the loins to force the femoral head against the ilium, with a perimeal band to relieve upward pressure is to be recommended. SYNOVITIS. Synovitis is an inflammatory affection of the lining membrane of a joint. It occurs chiefly in adults, and may affect one or more articula- tions; none are exempt ; but the knee, wrist, ankle and phalanges are most commonly involved. Certain diatheses, such as the rheumatic, tuberculous, and syphilitic, predispose, whilst contusions, sprains, disloca- tions, neighboring disease, and wounds act as exciting causes. A rigor, with slight elevation of local and general temperature, pain, and creak- ing upon motion, fixation, moderate swelling, and, a little later, effusion and fluctuation, mark its advent. The synovial membrane becomes blood-red in color and swollen, sheds its superficial cell layers and exudes serum, at first limpid or, perhaps, tinged with blood, which speedily becomes turbid, or, in the most intense varieties, purulent. When located in the knee-joint, the patella is floated from contact with the femoral condyles when the leg is extended, and when pressed upon displaces the underlying fluid and comes into palpable contact with the bones beneath. Simple acute synovitis is to be treated by absolute rest in an extended position, by cold applications, local abstraction of blood by leeches or cups, counter-irritation by blisters, and, in some cases, by the application of firm bandages over wadding. Rest may be secured either by splint or extension apparatus, but it must not be persisted in longer than the more acute stage, when cautious passive motion and massage should be instituted to prevent adhesions. |FIG. 261.

Purulent synovitis is a serious complication, recognizable by recurring rigors, persistent high (103°) temperature locally, constitutional disturb- ance, and by hypodermic aspiration. It is to be treated, first, by aspiration and washing-out of the joint, and, this failing, by incision and drainage, or by excision of the membrane if that alone is involved. Septic synovitis is extremely resistant to treatment, often requiring in addition to the usual constitutional and local measures such operative procedures as will be described under FIG. 262. arthritis, and as frequently resulting in ankylosis or destruction of the joint. Its cause, pathology, diagnosis, and treatment are practically identical with the septic form of the latter affection, as the process occurring in the synovial membrane in- variably extends quickly to other struc- tures of the joint. Syphilitic synovitis much resembles simple acute and subacute synovitis, but is dependent upon and intercurrent with the constitutional disease, and promptly yields to anti-syphilitic treatment. It may be acute or chronic ; is limited to adults; is symmetrical, and usually occurs in the knees. Some swelling and effusion accompanies it, but scarcely any pain. Occasionally synovial membranes undergo a fibroid change of probably rheumatic nature, and minute sessile or pedunculated whitish fibroid bodies are developed throughout the membrane. These, during movements of the joint, may become separ- ated from their attachments and form a Fibroid hyperplasia of synovial variety of “loose bodies” in joints. A membrane of knee. (DRUITT.) second variety of this same process exists where the fibroid masses are developed in the deeper layers of the membrane. Here they become flattened by joint motion, and bear great resemblance to melon seeds, by which appellation they are commonly known. These and other fibroid changes of the synovial membrane occur in rheumatic arthritis. Nothing short of excision of the affected membrane can afford any relief from these affections. Primary and metastatic neoplasms of the synovial membranes rarely occur, but cannot, as a rule, be accurately diagnosed save by opening the joint. Effusion will usually be present. * § º | bº º º § HAEMARTHROSIS. Haemarthrosis results from laceration of the bloodvessels of the synovial membrane. It may occur in conjunction with synovitis, or exist sepa- rately. Blood quickly distends the cavity of a joint, but does not clot unless it has communication with a fracture. Marked fluctuation is A R T H R ITIS. 449 frequent, but there is usually no pain or increase of heat, and upon hypo: dermic aspiration pure blood is withdrawn. Small quantities of blood thus effused into healthy joints is rapidly absorbed under pressure, but otherwise must be withdrawn by aspiration. Persistent effusion after injury, without pain, will almost invariably prove sanguineous. Haemar- throsis followed by degenerative joint change is common in haemato- philics, when it should not be interfered with surgically, unless its causa- tive condition has first been effectively cured. Hydr.ARTHROSIs, or simple non-inflammatory infiltration of joints, is usually a part of a general oedematous condition of an extremity having origin in heart, liver, or kidney disease, or in venous obstruction or dis- tention. It can only be relieved by removal of the ulterior cause, together with elevation and elastic pressure by bandages. ARTHRITIS. When an inflammatory process has originated in or been engrafted upon other portions of a joint than the synovial membrane, it is termed arthritis. Practically, however, the distinction between synovitis and arthritis is frequently impossible and as often immaterial as regards treatment; the synovial membrane being invariably involved, either primarily, secondarily, or synchronously with other portions of the articu- lation. Arthritis may involve a whole joint or be limited to any portion of its extent. Identical varieties are apt to present at once more severe constitutional and local phenomena than do the corresponding forms of synovitis, but its development, on the contrary, occasionally is most insidious. Simple acute or chronic arthritis takes place as a rarity. Almost all cases of arthritis are to be included in the chronic, septic, specific, and neurotic varieties. Acute suppurative arthritis is a purulent inflammation of the entire contents of a joint. It may involve one or many articulations at once or consecutively. The causes are either contusions or wounds of the joints, contiguous inflammation as in epiphysitis, by burrowing of pus from periostitis beneath the periosteum into the joint, or rupture of an abscess of the bone head into the articulation. The pathology of the affection is simply that of acute suppurative inflammation of all the elements of the joint; the cartilages erode or necrose, purulent or sanio- purulent effusion takes place, producing abscess of the joint, which subse- quently may rupture externally or penetrate into the surrounding tissues. Finally, the joint may return to a non-inflammatory ankylosed condi- tion, or necrosis of the adjacent bones may take place. Taking the knee, for example, pain increased by motion, chill, temperature rising to 102° to 104°, and swelling will be the initial symptoms. Fluc- tuation, great swelling and oedema, and severe constitutional depression With high pulse, will, together with aseptic hypodermic aspiration, render the diagnosis certain. Before the diagnosis of pus can positively be made, the jºint must be put at rest by splints, and evaporative lotions, ice-bag, or irrigations applied. When pus is recognizable (sometimes when only suspected) the joint should be tapped and washed out, or, especially if Plls recur, be laid open and drained. Constitutional support and stim- ºlation, antiperiodics, and concentrated diet are of prime importance. Such treatment will sometimes save a joint and preserve fair motion, but 29 450 DISE ASES OF JOINTS, CARTILA GES AND LIG AM ENTs ankylosis is usual. Later stages will probably require excision or ampu- tation. Except in pyaemic cases, these latter measures should, when indicated, never be delayed if the patient can withstand the shock, for the rule is constant loss of strength without recuperation whilst the sup: purative process lasts, and the danger of further constitutional contami. nation is great. Gomon'rhoeal Arthritis. Gonorrhoeal arthritis is caused by metastasis of gonorrhoeal pus from the urethra, is almost limited to the male sex, and involves as a rule a single large articulation, but may be symmetrical, or attack any, even phalangeal joints. All parts of the joint are involved. There is great pain, worse at night, Swelling and Oedema; pressure and motion are ex- tremely painful, and grating may be present. Plastic exudation, rather than effusion, takes place, which exudate commonly organizes into fibrous material which more or less completely obliterates and ankyloses the joint. The urethral discharge, which may be either from acute gonor- rhoea or chronic gleet, is not usually in any way affected by joint involve- ment; but on the other hand, treatment of the discharge often has a marked beneficial effect upon the diseased joint and will prevent other articular involvement. Gonorrhoeal arthritis is extremely resistant to treatment and very apt to pursue a long chronic course. Absolute rest, leeches, counter-irritation by a series of small blisters, morphia for pain, and a liberal use of belladonna and mercurial ointments upon the joints, in conjunction with good diet and hygienic surroundings, are the most beneficial remedies. Tubercular Arthritis. Tubercular arthritis usually takes origin from extension of tuberculous disease from the contiguous bone extremities, but may also arise primarily in the synovial membrane. The tubercle bacillus is invariably present, actively causative, and diagnostic. This form of arthritis is most common in childhood or youth, but may arise at any age. In aged persons the process is apt to run a rapidly destructive, almost irremediable, course, speedily breaking down the joint and involving adjacent bones. The strumous or tubercular diathesis invariably precedes and predisposes to joint infection, whilst depraved physical condition or slight traumata serve as exciting causes. It frequently follows such diseases as measles, Scarla: tina, and typhoid fever. The malady may be limited to one or several joints, or be concomitant with or consecutive to tuberculous lesions else- where. * PATHOLOGY..—Primarily tubercles are deposited in the articular ex- tremities or membranes of the joint. Then follow irritative inflamma- tion, serous succeeded by purulent effusion, distention and progressive softening of the joint capsule and ligaments, ending in their rupture or disappearance. The membranes and cartilages are replaced by a fibrouš, gelatinoid, yellowish or brownish substance; the bone-ends are invaded, abscesses form and discharge, leaving sinuses from which sequestræ 0" granular portions of bone may be discharged. Finally, by continuous reflex muscular contraction, the bones forming the articulation are drawn asunder, giving rise to great deformity and disability. The process may be arrested in the earlier stages, when the parts may return to the normal TUBER CU Lo Ús ARTH RITIS OF SPECIAL J OINTS 451 previous condition, or the inflammatory products may organize and pro- duce intra-articular adhesions and more or less ankylosis. Symptoms.-Slight impairment of function is earlier or later followed by pain and swelling. Pain may be absent until later; it is not essential, or at all characteristic. No impaired function even may be discernible at first, save on close examination. The temperature of the body or part may or may not be raised. Soon the articulation assumes a white swollen appearance; blue veins are apt to course over its surface, and upon palpa- tion a sensation of “doughy” fluctuation is apt to be observed, which, later, will probably be succeeded by true fluctuation, lateral move- ment, grating, abscesses, sinuses, and discharge of disintegrated bone and cartilage, spiculae or sequestra, and dislocation. Hectic will be present if the joints have become infected through the sinuses, but not if that accident has been prevented by proper treatment. If purulent dis- charge has been of long duration, amyloid disease may complicate the case and interfere with treatment. TREATMENT.-Absolute rest of the joint for a long period, with good food, tonics, iron, cod liver oil, and such measures as have been sug- gested for synovitis and simple arthritis, such as cold applications, leeches, blisters over points of greatest pain, applications of iodine, and pressure by bandages, is the treatment for all but the later stages. Should the process still continue, excision of the joint membranes and other tubercu- lous foci in the cavity (erasion) is called for. Next in order comes excision, and, lastly, if the joint is utterly destroyed or the bones hope- lessly involved, amputation of the extremity. PROGNOSIS.–Many cases appear to recover perfectly when the disease yields to minor measures; others preserve simply a stiff or ankylosed joint. Excision and erasion are very successful, if not left too late. But many live for years with discharging sinuses without much discom- fort other than more or less loss of function. Constitutional infection is supposed to occur frequently, if the disease is not eradicated. Tubercular meningitis is not rare at any period. Amyloid degeneration of the kid- neys and other organs sometimes results from continued purulent dis- charge. Joints cured by minor measures are liable to recurrence upon even trivial aggravation or injury. TUBERCULOUS ARTHRITIs OF SPECIAL Joints. Tuberculosis of Vertebral Articulations (Spondylitis, Pott's Disease). Tuberculosis of the vertebral articulations conforms, with modifications due to location, to the general description of joint tuberculosis. Thus situated the affection is most apt to develop between the third and six- *enth years, but no period of life, from a few days up to about the *Ventieth year, is entirely exempt. Any joint or joints of the spine, from the occipito-atloid to the lumbo-sacral or even inter-coccygeal, may be affected. The lower dorsal region is most usually involved; then, in Order of frequency, come the dorso-lumbar, cervico-dorsal, cervical, lumbar, lumbo-sacrai, atlo-axoid, occipito-atloid, and inter-coccygeal. The disease may develop simultaneously or secondarily in two or more distinct º or travel through a considerable number of contiguous ver- *...ither upward or downward. It may be an entirely local disorder, **nifestation of general tuberculosis, or itself may originate the latter. 452 DISE A SES OF JOINTS, C A RTILA GES AND LIG AMENTs. The course of vertebral tuberculosis is, as a rule, slow and chronic, but exceptional cases and those which become infected through abscess open- ings may run a very acute and rapid course. A history of traumatic cause or origin is almost always presented with the case. Slight direct or indirect traumata are probably determining and exciting causes, but the tuberculous constitution must be present to render them efficient. Violent injuries of these, as of other joints, are mot likely to be followed by tuberculosis. It may arise from infected spinal wounds. PATHOLOGY..—As the medulla and epiphyses of the vertebrae remain soft and embryonic until long after other cancellar tissues have undergone the permanent changes of adult bone, they are more predisposed to inflam- matory affections than other bones. Hence, tubercle bacilli find a more congenial bone location in the pulpy Osteo-cartilaginous or epiphyseal junctions of the vertebrae than elsewhere. At these points the disease in almost every case begins, although it is possible that some few originate in the inter-vertebral fibro-cartilages or synovial membrane, except in the occipito-atloid, atlo-axoid, and inter-coccygeal varieties, when the disorder commences as a tubercular synovitis or in the odontoid process. In every case the joints are quickly involved and adjacent cartilages and bone are broken down. The destructive process is always confined to the bodies of the vertebrae, while the laminae and spinous processes escape. At this stage, before deformity takes place, the disease may naturally, or responding to treatment, cease, the products organize or casefy, and no special harm be done. But much more usually it progresses; the bodies of the vertebrae on either side of the first affected joint become carious and crumble down, or necrose and throw off sequestrae; the super-imposed portions of the spine are drawn forward and downward by gravity and action of the abdominal muscles, deformity results, abscesses may form and burrow in the peri-spinal sheaths and perhaps infect new portions of the column. If unretarded, the process may continue until many separate or contiguous vertebral bodies are destroyed, great deformity has supervened, and the patient finally succumbs to suppuration and exhaustion. Unless the case is complicated by old lateral curvature, the deformity is always directly antero-posterior, because the spinal arches, articular spinous processes, and the lateral sup: ports of the column are not interfered with. The projecting portions of the deformity are due to the pushed-out spinous processes. Where the seat of the disease is situated in the lumbar region, deformity does not appear or comes very late, because the natural anterior curvature of the spine at this point must first be overcome before angulation can become evident, as well as because of the rigidity and broad articular surfaces of this region. Suppuration is not a good index of the disease; it (abscess) may present in advance of other symptoms, or not appear until destruction is great. Some worst cases are never complicated by its presence. Abscess is dis- covered in about twenty-five per cent. of all cases, but it occurs without being fully demonstrable in as many more. At post-mortems they are usually found concealed or sacculated, and if the case recover the suppurº tive products may have organized, caseated, or have formed residual abº scesses. A variety of vertebral tuberculosis has been recorded in which the bodies of the bones become honey-combed, but do not suppurate, break down, or produce deformity. g Contrary to conventional belief, angular deformity does not give rise tº direct pressure upon the cord, except in rarest of instances, and when the TU BERCULO Us A RTH RITIS OF SPECIAL J O INTs, 453 disease is located at the atlo-axoid junction. Actually, there is much more than the usual space for the cord to pass through when angular deformity exists, as then the anterior wall of the canal is replaced by an excavation. But such deformity by approximating the ribs may give rise to pressure symptoms or destruction of the nerves emerging laterally from the spinal column. In alto-axoid disease the atlas is displaced forward upon the axis, the posterior arch of the former compresses the cord more and more against the odontoid process of the latter, and gradual or Sud- den extinction of the functions of the cord, and death, may result. The paralysis of the more ordinary forms of the disease is due to secondary inflammatory affections of the cord and membranes, and to pressure from pent-up pus, hemorrhage, as from ulceration into the vertebral artery or other vessel, or from a displaced sequestrum. If the displace- ment or pressure be gradual in onset the cord will often accommodate itself to it, and can carry on its varied functions through a very much narrowed spinal canal. Therefore, it is not strange that many palsies of tubercular spondylitis are often erratic, anomalous, and, on occasion, the first symptom of trouble. Angular deformity in the cervical region forces the chin upon the chest and may produce dyspnoea, while in the dorsal region the same effect follows compression of the thoracic viscera, whence mechanical dyspepsia and intercostal neuralgia may result. The paralysis of vertebral disease is essentially motor, and always com- mences as such. Sensory function is last to appear and first to return where improvement takes place, because the motor tracks being anterior bear the brunt of the pressure, while the sensory are posterior and more protected. Owing to sympathetic connections, however, entire control of the bladder and rectum sensations and functions is never entirely lost. By continuity, or by abscesses opening into the spinal meninges, tuber- culous spinal or cerebro-spinal meningitis may be produced, but more frequently the latter arises from general miliary tuberculosis—both rare Complications of vertebral tuberculosis. When spinal abscesses form pus collects in front of the affected vertebrae; upward progress is shut off by the overhanging, displaced vertebrae, and in other directions the anterior ligament, periosteum, and pleura or peri- toneum thicken and form an abscess wall so that the pus, to make its way Out, must find exit on one or other side of the spine and enter one or both of the sheaths of the psoi muscles, and destroying the contained muscle present in the iliac fossa, groin, or thigh as a psoas abscess, or pass back- Ward through or external to the quadratus lumborum, and give rise to a loin or lumbar abscess. Cervical spinal abscesses by much the same process point either in the pharynx or find their way along the fasciae and muscles to some point upon the neck. When cure is established, after deformity has taken place, true or Osseous ankylosis of the affected vertebrae takes place, inflamma- tºry, products are organized, absorbed, or encysted, the muscles relax their Vigil, and the cord becomes accommodated to its altered position. Firm *nkylosis is to be desired in any part of the spine.

SYMPTOMs are frequently obscure at first and extremely palpable after- Ward. The appearance of a boss of unnaturally prominent spinous pro- * may appear without prodromata and constitute the first sign. It is 454 DISE A SES OF JOINTS, CARTILA GES AND LIG AMENTs. at this stage that most of the cases amongst the poorer people are brought to the surgeon. , Stiffening of the spine and nerve symptoms usually long precede recognizable deformity. Pain will usually attract the person's attention and may be mistaken for colic, muscular cramps, dyspepsia, rheumatism, neuralgia, or “growing pains.” It is aggravated by motion or concussion of the spine, as in riding in a carriage, over crossings in a street car, or by missing a step; is always referred to the same locations and is relieved by rest. It is usually complained of as intercostal, sub- sternal, sciatic, or as headache of the occipital distribution when the dis- ease is located in the cervical spine. Some local pain or tenderness may be present, but this is usually dull, whilst the referred pains are apt to be sharp. Before actual pain develops various minor sensations, as tingling, burning, formication and itching, may be present. It may be referred to the hip, which, accompanied with spine lameness or alteration of gait, may cause error in diagnosis. The sensation as of a cord tied tight around the chest or abdomen, and spasmodic abdominal attacks with accompany- ing or subsequent flatulent distention, are not uncommon symptoms. Pain and muscular tension can usually be relieved at once by longitudinal ex- tension or by bending the spine in a direction contrary to the angle of deformity, as by a hand placed under the back and the patient thereby partially raised. In rare instances, however, they may thus be aggravated. Elevated temperature may be a prominent or an absent feature of the case. When acute it rises to 101° or 102°. If abscesses become infected it may rise higher, and then become of hectic type. A high temperature, except at first, or upon abscess infection, will indicate grave complications, Paralysis or other severe nerve symptoms may occur at any stage, as also may those of spinal inflammation, cerebro-spinal meningitis, general miliary tuberculosis, phthisis, hip disease, empyema, and peritonitis. At once, or after a lapse of months, or even years, prominence of the spines of the affected vertebræ and angular deformity appear in varying degree. So, also, is it the case with abscesses; they may present early, late, not at all. Anaesthesia may be required for their diagnosis if deeply situated. Very late loss of motion, then sensation, and finally contrac- tion of leg-muscles, bedsores, or amyloid degeneration of viscera may supervene; the muscles waste, and the patient becomes excessively blood- less, pallid, and of aged appearance, even if very young. g Certain special symptoms pertain to atlo-axoid and occipito-atloid dis- ease. There may be spasm of the sterno-mastoid or choreic movements of the neck muscles or neuralgia or paralysis of the brachial plexus, all of which are increased by nodding rather than by rotation, and relieved by occipital extension. Laryngeal cough, or stridor, difficulty in respi- ration, deglutition, or phonation may be present. Sometimes grating or crepitus can be developed by motion. The head is stiff, thrown forward or to either side, the chin forced upon the sternum, the neck appears shortened, and the spine of the axis is extremely prominent. Rarely the head in addition to being thrown forward is turned upward by spasm of the posterior neck muscles. The head is held in the hands when the disease is extensive; there is danger in any movement; the patient is apprehensive of sudden death and cannot lie down or lean forward. There is constant danger, in extreme cases, of sudden dislocation 9." fracture, pressure upon the cord and instant death. Abscesses of this region usually point in the pharynx or upon the neck. DIAGNOSIS.–With this end in view the patient should be stripped naked in a warm room and stood before, or laid across the knees of the surgeon. TU BER C U L O U S A RTH RIT IS OF SPECIAL J OINT S. 455 All cases wherein there is any possibility that disease of the spine may be present, to account for distant or obscure symptoms, should be thus examined. Spinal pains can best be elicited by motion of the column and pressure in its axial direction. Percussion, applications of electricity, heat or cold, are most unreliable. Muscular symptoms are, perhaps, most important. Almost as soon as disease commences the erector-spinae muscles involuntarily assume the Sup- port of the column to prevent movement of, or pressure upon, the diseased part. This gives rise to characteristic postures and modified movements, recognition of which is most to be desired, for treatment instituted at this stage is highly successful and prophylactic. No skill is required to diagnose later stages when deformity has taken place, nor will treatment then avail for much. The characteristic posture is one of caution and apprehension. The child tires of play, lies about, or FIG. 263. seeks support; is easily fatigued. Com- plains, perhaps, of local or referred pains or other sensations, is clumsy in walking, or struts or shuffles along without elasticity.

I concede the possibility, indeed the belief, that other than tuberculous forms of inflammation of the spinal joints and bones take place, but think (as treatment would, in all cases, be identical and so little is known of the other varieties) to prevent confusion by omit. ting their description. TREATMENT is of greatest value in the earlier stages, when the disease may often be entirely checked. The great indications are to build up the vital powers and to secure local rest. The former is to be attained by attention to the hygienic surroundings and diet of the patient, and by the administration of such agents as cod-liver oil, iron, iodide of potassium or mercury, hypophosphites, Strychnia, and, perhaps, phosphorus. A little brandy can often be added to the diet with advantage. Removal to sea or country air will usually make marvellous changes for the better. Even if it is necessary for the patient to remain in bed, he should be placed upon a hard hair mattress cot, which can be carried into the yard, to the roof, or to another room. Massage, electricity, and douching must not be neglected. From the first appearance of symptoms until consolidation has well advanced (most certainly while any acute symptoms last) the patient should be kept in bed, and, as much as possible, motionless upon his back. While symptoms are very acute sand-bags may be placed upon each side of his body. Even greater repose can be secured when FIG. 264. # th: .

(WYETH, after REEVES.) indicated by applying extension to the neck and elevating the head of the bed; by its application to the legs and elevating the foot of the bed, or by the conjoint application of both methods. It is also well to place a small pillow under the angle of deformity, or to sustain that portion of the body in a sort of sling, after the manner of Reeves. I do not wish, however, by this advice to be construed as endorsing methods which tend to correct forcibly the deformity, which, in my opinion, are ill-advised and contrary to the teachings of pathology. Neck extension is especially called for in cervical disease. The object of treatment by posture and moderate extension is to relieve muscle tension, and pressure upon the affected vertebrae; by which are secured consolidation with least deformity, and comfort to the patient meanwhile. Desperate cases, where bedsores are threatened, must be placed upon an air- or water-bed. When acute symptoms have subsided, the patient may be allowed tº get up and go about in a brace. Where limited circumstances prohibit more expensive apparatus, the plaster jacket, while not so light, conve. nient, or comfortable as other apparatus, yet answers every purpose of treatment. TU BER C U LO U S A R T H RIT IS OF SPECIA. L J O IN TS. 457 For its application the patient should be stripped to beneath the hips, or entirely, and a close-fitting woollen shirt, extending below the trochanters and provided with shoulder-straps, put on.

A folded towel should be placed over the lower abdomen to allow for subsequent distention of the stomach by food, but this can be dispensed with if the patient has recently partaken of a meal.

Where circumstances permit, it is much preferable to use the plaster jacket simply as a mould in which is cast a plaster model of the body, around which is accurately fitted a leather or felt jacket, which is subsequently trimmed, fitted with eyelets, and extensively perforated. º TU BERCULO U S A R T H RIT IS OF SPECIAL J O IN T S. 459 The above will answer perfectly for all diseases located below the upper dorsal region. Otherwise a supporting head-gear must be fitted to the jacket. This is done by either fastening the head-piece between the folds of bandages or by subsequently riveting it upon the completed brace. For disease of the cervical spine and of the º º ſº |tº * º | occipito-atloid region, the “jury-mast” head- gear will not always afford sufficient security. Then some such device as the leather collar is more appropriate, and the jacket is dispensed with, but such cases had best remain in bed until firm ankylosis has taken place. Remov- able jackets need not be worn in bed.

Nothing but the shirt, or shirt and chemise, must be Worm beneath the jacket, and it is well for each patient to have a suspension apparatus and put on his brace while the spine is extended.

Such infection usually gives tenfold impetus to the disease, and may cause speedy death by suppurative exhaustion. In opening abscesses, absolute antiseptic precautions should be taken. Free incision is made, the sac washed out with 1:1000 bichloride solution, freely curetted as far as possible, again washed out and the incision sutured, leaving in a large drain. A large dressing should then be ap- plied and renewed, and the sac re-washed upon the slightest indication therefor. Thus treated, their opening causes none but beneficial results. Psoas abscesses, if detected in time, can be more easily dealt with by cutting down upon the sac above Poupart's ligament. PROGNOSIS.—Tubercular spondylitis is rarely fatal under ordinary cir- cumstances. Prognosis depends upon the age of the patient, the duration and location of the disease, and whether abscesses have formed or have become infected. High cervical disease is always dangerous, occasionally suddenly fatal. TUBERCULOSIS OF THE SACRO-ILIAC ARTICULATION. This seat of tuberculosis is not uncommon, and often, especially during early stages, is confounded with sciatica and hip-joint disease. It occurs rarely in children; between the ages of fifteen and thirty-five it is most common. The causes are either local traumata or extension from the acetabulum or from iliac or hip-joint abscesses burrowing into the articu- lation. The symptoms are pain, local and radiating, tenderness upon pressure or motion, especially when pressure is made upon the iliac crests, perhaps interference with or painful defecation or urination, and, rarely, oadema of the corresponding limb from swelling pressure upon the iliac vein. The body is inclined to the sound side to secure absence of pressure, and exten- sion by weight of the sound limb. Swelling occurs early, but does not shift from over the line of articulation or obliterate the gluteal fold, but later, especially when abscess forms, the tumefaction may extend to and change the buttock contour. Always there is wasting of the gluteal muscles and loss of power in the limb. Apparent lengthening of the limb is due to dropping the pelvis to secure ease; the foot is everted. Abscess may subsequently form and point locally, or discharge into the pelvis or its contained organs, through the sciatic foramen into the but- tock, via the levator ani and obturator fascia into the ischio-rectal fossa, or upon the inside aspect of the thigh. & The affection must be differentiated from spinal or innominate caries, hip disease, and sciatica. & Treatment of the early stages should comprise strict rest, extension, proper diet; plus blisters, cautery, or iodine paintings locally. Later, if all goes well, a hip case or splint, or crutches may be allowed. If by these means progress of the disease is not quickly arrested, and more pºlº ticularly if abscess supervene, the joint must at once be laid open by in- cision of its own direction and length, and the diseased portions of the membrane or bone scraped or chiselled away. Following this the wound should be kept well packed with antiseptic materials until it heals. Often all that we can do will not prevent the patient finally dying from exhaus' tion. TU B E R C U L OSIS OF HIP - J O IN T. 461 Tuberculosis of Hip-joint. Tuberculosis of the hip-joint is a disease very frequently met with. Two-thirds of all cases are under sixteen years of age ; males are most often affected. It may attack one hip or both either synchronously or at different times. CAUSEs are, in order of frequency : injury, spontaneous, and auto- infection from other organs or tissues. PATHOLOGY..—The inflammation may begin as a tubercular epiphysitis of the head of the femur, and, the epiphyseal junction being entirely within the joint-capsule, thence quickly spread to the other articular structures. Or it may take onset upon the acetabulum floor in the lines of union of the three segments of the ilium ; in the synovial membrane; or, possibly, in the ligamentum teres. But most usually the disorder is supposed to originate in the Osteo-cartilaginous junction of the femoral head. According to the constitution of the patient the case will run either an acute or chronic course. If acute, profuse suppuration and breaking down of the contents of the joint and necrosis of the neighboring bones take place. Or, if epiphysitis has taken place, the head of the femur may become entirely detached into the joint. The worst forms are those where the tuberculous process is transmitted along the bone shafts, through the bottom of the cotyloid cavity into the pelvic bones or their neighboring organs, or into the blood current as miliary tuberculosis. In the chronic variety, on the other hand, the disease is persistent; pus is not formed, or only slowly, the effused materials are plastic, become firm and, in time, give rise to fibrous, rarely osseous, ankylosis. In either case, but especially the former, destruction of the joint plus continuous muscular action may dislocate the altered head or neck of the femur upon the dorsum ilii and give rise to great deformity. SYMPTOMS.—Often before positive symptoms develop, the child is noticed to exhibit lassitude, to tire easily of play, become pallid, sleep uneasily, lose strength, and, perhaps, be feverish. He eases the affected limb in exercise, play or standing, and, possibly, may complain of what are vul- garly taken for “growing pains” in the knee, thigh, or hip. Great atten- tion should be paid to these conditions, as diagnosis at this stage is of vital importance. Yet, no one sign can be depended upon more than to centre attention upon the parts, and, perhaps, indicate precautionary treatment until others develop. Stiffening will be the first positive symptom and give rise to lameness and a characteristic standing posture, where, leaning a little forward, all Weight is thrown upon the sound limb, while the other is advanced, slightly flexed, abducted, and rotated outward. Stiffening of the joint in varying egrees of flexion, at first by muscle tension to prevent motion, and later by joint changes, is present in all stages of the disease. Even in the slightest amount it can be recognized by placing the child flat upon a table, and upon attempting to straighten out the affected leg, the vertebrae become arched forward by tension upon the psoas and iliac muscles and the hand can readily be carried beneath. When the sound limb, which, to gain the confidence of the child, should first be examined, is so manipu- lated, no change in the back takes place. This involuntary muscular tension, which is shared in by all the anterior muscles of the thigh, is to Protect the joint from motion and consequent production of pain. The degrees 9f flexion, abduction, and rotation, indicate that position of the Joint which gives most room to accommodate the effusion always present 462 DISE ASES OF JOINTS, C A RTIL AGES AND LIG AM ENTS, in the joint; later, flexion may depend upon excessive muscle contrae. tion. Impaired motion of the joint is amongst the most valuable of early signs. If motion is unimpaired, it is almost conclusive evidence that no hip disease is present. Interference with extension and flexion may be FIG. 271.

(SMITH,) caused by spinal disease, but rotation (the crucial test) is only impeded by hip-joint involvement. To apply the test, flex the thigh to an angle of 120 degrees and then attempt rotation. All manipulations should be most gentle, cause little or no pain, and, except to diagnose very late complications, anaesthesia should never be employed, as it will relax all muscles and thus defeat our object. Pain, while usually present in some degree locally, yet is most com- plained of about the knee, over the patella, or upon the inner side of the thigh. Especially is it referred to these parts when the disease is located in the femoral head. The mechanism of this referred pain is not clearly understood, but, undoubtedly, the proximity of branches of the obturator distribution in part explains it. There are no referred pains at first, when the process primarily involves the synovial membrane, but local pain from capsule tension is severe and constant. When the capsule is tense there is much tenderness in the groin and above the great trochanter. Sudden ceasing of long-continued severe pain indicates that the capsule has given away and the fluid joint contents have escaped into the sur: rounding tissues. Night starting and sudden cryings out (ostitic cry) during sleep or waking moments are common, being due to the muscles having, during sleep, relaxed their vigil only to assume rigidity again suddenly and painfully as the child awakens. Pain, both locally and referred, is increased by inward pressure upon the great trochanter; Pounding the heel or flexed knee is a very crude and valueless method of developing hip tenderness. Patients suffering acutely from hip-joint distention occasionally can gain more relaxation of capsule and quietude, hence comfort, by crossing the knee over the sound thigh or by hugging it upon the abdomen or chest. e Swelling is early and most noticeably developed in the synovial variety. TU B E R C U L OSIS OF HIP - J O IN T. 463 Great heat and redness do not, as a rule, accompany it, except in acute tuberculous abscesses of the joint or surroundings, but more or less local rise of temperature is present... Swelling is most apparent in the groin, where the inguinal glands will be very prominent, about the great tro- chanter, and, in a minor degree, in the buttock, and about the joint generally. * Muscular Wasting or Atrophy early sets in and involves the joint sur- roundings and the entire limb.

Comparative meas- FIG. 273. urements of the calves and thighs will demonstrate the presence and amount of atrophy, Wasting of the gluteal muscles, together with the swelling in that region, flattens and broadens the buttock, shal- lows or obliterates the natural crease or fold and creates a deviation of the internatal line toward the sound side. To observe gluteal changes the patient is stood naked on a table, his back to the surgeon. Compensating Postures.—Continued hip disease from muscular tension in time gives rise to a lateral curvature of the lumbar spine and compensating curve in the dorsal region. This, with abduction of the thigh, makes the leg appear lengthened. But Diagram showing until great bony destruction, or actual dislocation flattening of buttoº of the joint occurs, changes in length of the limbs and lowered position do not occur, except rarely, when great distention of gluteal crease on of the capsule forces the femur away from the ace- diseased side. tabulum and produces moderate lengthening. Care- ful measurements of the position of the trochanter will prove its position to be unchanged in most cases. Apparent changes in the length of the limb are simply the result of compensatory postures, which permit loco- motion without motion of the affected joint. Déſormity, up to the later stages, is purely muscular. But when the capsular and other ligaments are destroyed, and especially when, in addi- tion, the head of the femur has been shed into the joint, or both head, neck, and the margins of the cotyloid cavity have been eaten away, dis- 19eation of the femur upon the dorsum ilii is very apt to take place through influence of continued muscular action. Pain then ceases and the limb becomes, from spasm or inflammation of the adductor muscles, adducted and inverted. When both hip joints become thus dislocated the legs are crossed in adduction, and produce what is called “scissor leg” deformity. . Dislocation is determined by the position of the trochanter, gharacteristic deformity, and actual shortening. Accidental force applied in the length of the limb may drive the femoral head or neck through the floor of the acetabulum if the latter is much diseased and eroded. Occasionally it becomes entirely destroyed, and the femur slips into the pelvic cavity without aid of outside force. 4bscess is a very frequent, generally inevitable, symptom and compli- Sºtion. Neglected cases almost invariably suppurate. It may, or may * Produce constitutional disturbance unless septic infection take place, When hectic and some degree of exhaustion are certain to follow.

In either case the pus, earlier or later, finds its way to the surface. It is supposed that certain abscesses may form in the inflamed joint surroundings without rupture of the capsule. Abscesses which point below Poupart's ligament are most common and come directly from the joint. Those which appear above that ligament find their way through the acetabular floor into the pelvis, and thence to the surface, or into the rectum, bladder, or intestines. Either variety, however, may point in the gluteal or ischio-rectal regions. The latter must not be mis- taken for simple ischio-rectal abscess or fistula. DIAGNOSIS.—By application of the above given diagnostic signs of hip tuberculosis, and of those of the respective diseases which follow, it may be distinguished from rheumatism, spinal or sacro-iliac disease, psoas or iliac abscess, periostitis of the upper femur, simple extra-articular abscess, spastic paralysis, and injuries or displacements of the femur. TREATMENT should be begun when disease is but suspected, and before unequivocal signs are present. The fundamental principles of treatment are: to build up the general health by such measures as have elsewhere been indicated, and to secure absolute rest for the joint until all acute symptoms have vanished. Great deformity and suppuration will occur unless treatment is thorough and early. To secure the necessary repose, the patient must be kept strictly upon his back in bed, with pulley extension and lateral sand-bags. He must not be allowed to sit up in bed. If necessary, a sheet across the chest or FIG. 274. # º * # Hºſſ # sº------- * *------. §º-º-º-º-º-º: Pxtension of the limb in a flexed and adducted position. (MARSIT.) under the arm-pits, and tied to the sides or head of the bed, must be em- ployed. If extension with the limb flat upon the bed produces pain or spine-aching, then the direction must be in the line of the flexion over a wedge-shaped pillow. Extension in the usual manner, in these latter cases, produces great intra-articular pressure by dragging upon the psoas and iliacus muscles, which act as the fulcrum of a lever. After this extension at the angle of deformity has been kept up some time the limb can, from day to day, without pain or resistance, be brought to better position and, finally, into the axis of the body. During extension the foot must be supported laterally and vertically to prevent T U BE R C U L OS IS OF HIP- JOINT. 465 consecutive deformity; to the same end and to prevent atrophy, massage of the limb, without motion of the joint, should be employed. A cradle to hold the bedclothes from the limb is also desirable. Counter-irritation about the hip FIG, 2.75. by blisters is of value in acute stages, and will often relieve pain. Excessive pain from joint distention can be at once stopped by aspirating the joint. The needle should be introduced through the gluteal, not the inguinal region, becaue of proximity of vessels in the latter locality. Pain can often be moderated by simple change of position, or of the direction of extension. Extension, as above described, must be kept up, perhaps for many months, until all acute symptoms have vanished and the thigh is in the body axis. Then the patient may gradually be allowed to get up, but must constantly wear a Thomas's, or other immobilizing apparatus, and still sleep with the extension apparatus applied. The removable extension apparatus of Morton (Fig. 276) is the most convenient for the latter purpose. When the disease has still further progressed toward cure, night exten- sion may be omitted; and when motion has become normal, or when consolidation of the hip is complete, the splint can be ten- tatively left off. Six to ten weeks will be consumed in the cure of even the most favorable cases. Non-use of the joint, alone, will never produce stiffening which cannot afterward be readily overcome. | Late stages of the disease may also de- mand extension or splints to prevent or = } reduce the shortening, dislocation, or other º deformity.

Abscesses need not be interfered with unless they produce pain or con- stitutional disturbance, or show tendency to open spontaneously. Then they should be freely incised, curetted, irrigated, drained, sutured, and Protected from septic infection by proper dressings. Abscesses which open themselves, or are surgically infected, at once set up hectic, and are very ºpt to lead to such changes in or about the joint as to necessitate sub- $9%uent excision or amputation. Abscesses which open above Poupart's ligament, or into the pelvic contents, are almost hopeless affairs, as they indicate pelvic bone involvement, which is practically unamenable to known treatment. Pxhaustion from continued suppuration may demand excision of the head of the femur and extirpation of the joint and infected surroundings. This may effect cure if all, or almost all, disease can be eradicated. 30 466 DISE ASES OF JOINTS, C A RTIL AGES AND LIGA MENTS, Otherwise, the patient will probably succumb to the effects of prolonged suppuration, or die of systemic tubercular complications. In suppurating cases, consolidation (usually inseparable from great deformity) is all that we can hope for; under the circumstances even that result must be con- sidered good, though years may be consumed in its attainment. If the disease has travelled along the shaft of the femur, or osteomyelitis has developed, amputation will be the patient's only chance for life. If the joint has become ankylosed in an awkward position, no treatment for its correction should be undertaken until the last traces of disease have long since disappeared. Then one of several operations may be employed: FIG. 276. Morton’s extension apparatus. The neck of the femur may be divided by introducing an Adams saw through a small incision immediately above the great trochanter and carried down until the neck is touched. After division of the bone and any resisting muscles or fascia, the extremity is brought into the axis of the body, and either in that position treated as a fracture of the same region, or, as soon as the wound has firmly healed, at once starting active and passive movements that a false joint may be established. Very fair position and function result from the latter procedure, or, if dislocation does not exist, the osseous material interposed between the acetabulum and femur may be divided similarly. A chisel should never be used for these purposes on account of the inevitable traumatism and splintering which are thereby produced. Excision of the head of the femur and division of resisting structures will also give equally good position, but with greater shortening and more uncertain function. Dislocations resulting from hip disease can never be permanently re- duced. Attempts thereat are very dangerous, and should not be considered. When a patient does not rally under treatment, but continues to lose ground, and especially when from continued suppuration, excision of the joint is clearly indicated; but, as operation in these stages is excessively dangerous, the chances of life with or without surgical interference must be most carefully balanced. Whenever large sequestrae or the separated femoral head can, by probe or finger, be felt, they should be removed by incision and the surroundings within reach curetted and washed out as thoroughly as possible. SY PHILITIC A R T H R ITIS. 467 PROGNOSIS.—Even in cases cured with good function some atrophy and consequent shortening will remain and the limb will never quite catch up to the other. Interference with the upper epiphysis makes this more marked. Cure with stiffening and deformity should be considered a good result in more advanced cases. The joint may suppurate, apparently hopelessly, for even years and then consolidate. It is never safe to say that any case cannot recover without operation. Amputation can sometimes be done with comparative safety when the risks of excision would be too great. Excision is often necessary in advanced stages. Months and years are often necessary to cure completely a well-marked case; eighteen months may be called the average duration of disease. Relapses are frequent, particularly should the patient be subjected to exhaustive con- ditions, or bad diet or hygiene. Other joints may become involved. Many cases succumb to intercurrent tuberculosis or other complications. Prognosis should always be most guarded. Syphilitic Arthritis. Syphilitic arthritis is a frequently overlooked disease, which is almost limited to adults suffering from tertiary syphilis, but may be developed in congenitally syphilitic children. During the later manifestations of syphilis the deep layers of the synovial membrane of one or more joints becomes infiltrated and swollen. This thickening extends to the sub- and superjacent structures, usually taking the form of innumerable vari-sized gummata. The endothelial layers of the synovial membrane are never primarily involved, but are FIG. 277. N. gº tº §: A \,{} ...Y *WS #lºº w ſ.ſº, ºgº ſº g § % * & º:42 º º 7| • • { 2 tº, Žnº ſiſ?

Extension, rest, counter-irritants, and anti- syphilitic remedies embrace the necessary treatment, to all of which, how- ever, the disease will often prove most obdurate. Firm, fibrous adhesions may remain after absorption of the gummata and more or less cripple the articulation, or, more rarely, the modules may soften, suppurate, and discharge into the joint cavity, giving rise to purulent arthritis. Syphilitic arthritis also as frequently invades a joint from the bone ends. Specific arthritis enlarges the bone extremities, giving rise to all the symptoms of syphilitic ostitis elsewhere, and the joint is speedily in- volved in suppurative destruction, which proves rebellious to all save heroic surgical measures such as excision, or even amputation. Osteo-arthritis (Arthritis Deformans). Osteo-arthritis is a form of chronic arthritis which is almost limited to later life, being disposed to by constitutional depravity and excited by diseased conditions of the proximal bone-ends or synovial membranes, and traumata. FIG. 278. º, y g º jº | }º ºğ. § §§ ºft | º 7 º’ ºffº. º | - º º ºf ſº - § it. - Changes in hip-joint dependent upon osteo-arthritis. (MARSH.) The disease commences in the articular cartilages, which rapidly lose their smoothness and pearly color, become of a yellowish tint, and wear away at the points of pressure contact, even into the cancellated structure of the subjacent bones, whilst at places, such as ligament and muscle attachments, where no pressure is brought to bear, cartilage hy: pertrophy and thickening occur and give to the joint a characteristic deformed appearance. One or more of these nodules may subsequently become isolated and become “loose bodies” in the joint. Later the synovial membrane becomes thickened and exceedingly vascular. At this stage effusion may appear, but is not inevitable: marked distention is always transitory; occasionally slight effusion may last throughout, but as often it will entirely disappear. Now the cartilaginous outgrowth; A T R O PHIC A R T H R ITIS. 469 begin to ossify, and from the wearing down of the bone the joint surface becomes broad and at the same time extremely mobile by the consequent relaxation of the surrounding ligaments and other tissues, which them- selves at this stage have become softened, atrophied, or even destroyed. Displacements of the bones composing the joint usually, at this stage, takes place, and great deformity results. Such displacements constitute a variety of so-called “pathological dislocations,” and are due to the con- tinual activity or spastic contraction of the neighboring muscles after the joint structures have been so weakened as not to be able to resist their displacing action. Ankylosis in any position may finally end the altera- tive process. The first symptoms of osteo-arthritis are dull, aching pains in the joints shortly followed by pain and creaking upon motion. Subsequent symp- toms depend greatly upon the rapidity with which the particular case may progress. The disease may run its full course in a few months or continue indefinitely. Frequently it has had origin in some form of in- jury, and without the exercise of great care in diagnosis deformities pro- duced by the arthritis may readily be mistaken for neglected fracture, dislocations, or other injuries. Treatment of this form of arthritis, un- fortunately, will almost always prove unavailing. Those measures which are best calculated to improve the general physical condition are always to be applied, together with massage, hot and cold douches, and perhaps counter-irritation locally. Excessive deformity can usually be prevented by splints, extension, plaster bandages, and division of tendons. Atrophic Arthritis (Charcot's Disease). Atrophic arthritis is a retrograde arthropathy which may develop in the later stages of locomotor ataxia. Etiologically, it is directly de- pendent upon those changes in the central nervous system which are present in ataxia, and most likely due to interference with trophic nerves. In its early manifestations the disease much resembles osteo- arthritis, but later runs a very distinctive course. The presence of a group of ataxic symptoms would always settle the diagnosis in favor of atrophic arthritis. Beginning in any joint or number of joints, but usually in the knee, the synovial membrane is thickened, and some effusion is poured out; grating with some pain and disability supervene and ostitic thickenings begin to form, Later, pain almost disappears, great absorption of contact points of the bones takes place, and wide separation of articulating surfaces with great resultant deformity occurs. The ligaments have by this time become greatly stretched and disintegrated; but a most sur. Prising and diagnostic symptom is the preservation of more or less loco- inotive function of the joint until a very late stage of the disease. Ostitic fºrmations are much less marked in atrophic arthritis than in osteo-arthri- tis, but erosion of the bones is markedly greater in the former. Months and years are usually required for the joint symptoms of ataxia 2 run their course, but occasionally instances are met with where but a few months are necessary to carry the process to its utmost limit. No spe- °ial local treatment can be recommended ; our efforts should be toward removal of the cause. 470 DISE ASES OF JOINTs, C A RTIL AGES AND LIGA MENTs. HYSTERICAL AND NEURALGIC JoſNT AFFECTIONS. These may be classed together, as both are purely subjective disorders. Though not identical they are frequently exceeding difficult to differenti- ate. Females more often than males are affected. In the hysteroid affec- tion pain may be complained of out of all proportion to other symptoms, perhaps combined with voluntary or involuntary fixation. Slight swell- ing of the joint may supervene, owing to increased vascular tension there- about, but more often the peculiar avascular condition of hysteria will render the joint pale and bloodless. Hyperaesthesia, either local or general, will be present; pain may be definitely located or shift its position. The joint can always be freely moved under ether, often also when the patient's attention is diverted or under application of extension when long continued; false ankylosis and muscular wasting may take place. Symptoms are mostly anomalous, varying, and inconsistent, and apt to be but a single group in an hysterical aggregate. Great caution must be observed, and close watching and repeated ex- aminations resorted to before positive opinion of these cases is expressed. Treatment of these neurotic joint affections should include special attention to the general health as well as the judicious use of massage, electricity, anti-neuralgics, and anti-periodics; possibly counter-irritation, prolonged extension, and occasional movements under anaesthesia. ANKYLOSIS. By ankylosis is meant that condition of a joint free from active disease in which motion has become restricted or abolished. When all motion is impossible ankylosis is complete; when partial mo- tion remains or can be developed, incomplete. Ankylosis may be true or false; true when the bones of the articulation have grown together by cancellated bone structure; and false when the joint is impeded by fibrous adhesions, situated within or surrounding its capsule. True ankylosis or osseous consolidation is also called synostosis. The con: dition is not in itself a disease, but is the result of prečxistent disease, and the term ankylosis should not be applied to the usual coincident stiffness of inflammation. In true ankylosis the joint as a joint is destroyed, the cartilages have disappeared over more or less of its area and the cancellated tissue of bone ends has grown together. True ankylosis, therefore, cannot take place until cartilage and its subjacent bone layer have been destroyed upon the surface of the joint. This may be accomplished by disease or by the Sur- geon, as in the complete bony ankylosis which follows a successful excision of the knee. The uniting bony substance may be extra- as well as intra-capsular, but the extra-capsular portion is usually nothing more than a calcification of ligaments or other surroundings, which is common to either variety. The joint cavity is generally totally obliterated before any bony union takes place. The true variety of stiffening always is caused by either fractures or long-continued destructive inflammatory disorder. False or fibrous complete ankylosis may be due to either of the above causes, to trophic changes, to organization of tuberculous or other dis- ease products, or to non-use of the articulation for a long period of time A N K Y LOSIS. 471 after injury or disease. The greater proportion of all joint restriction results from injury, when insertions of tendons are stretched or torn, the capsule lacerated, and blood or lymph effused. These products subse- quently organize and bind folds of the capsule as well as surrounding parts together and motion, becomes impeded and painful or impossible. Fibrous bands may also form connecting the joint surfaces. If these adhesions are not early interfered with they will firmly organize and contract or may even become calcareous. But again ankylosis of the false variety may be complete and yet every structure of the joint remain almost unchanged, all adhesions being extra-articular. Impeded joint-motion from outside cause, such as muscular spasm, hysteria, burns, cicatrices, etc., is termed “spurious ankylosis,” but may result in false ankylosis through contraction of and wasting of the joint- structures from long-continued inactivity. Nerve injury also may thus give rise to spurious ankylosis, especially when small joints are concerned. DIAGNOSIs of the variety of ankylosis can usually be made from the history of the case, but sometimes differentiation will be found impossible. Except in trivial cases, all manipulations should be made with anaesthesia. If the slightest motion remains the case is not one of bony consolidation. If judicious force under ether fails to produce movement, the case had better be considered one of bone variety rather than subject the part to dangerous manipulation, for with such firm adhesion the exact diagnosis would be of little aid in treatment. TREATMENT of ankylosis is extremely important and successful if properly apprehended and applied. It 'should always be instituted as early as possible, but never while the slightest heat or redness of the part persists, but a moderate degree of swelling may be ignored. Manipulation is of what treatment mainly consists. If this is productive of pain (and it practically always is) nitrous oxide or ether anaesthesia should first be in- duced. No great force is ever justifiable, FIG. 279. nor should a known case of true ankylosis ever be subjected to manipulation. If, with moderate force, adhesions are felt to break, the joint should gradually and gently be put through its range of motions, but manipula- * 2* ºv. ==== :2: Modified Stromeyer splint for Modified Stromeyer splint for ankylosis of elbow. amkylosis of knee. * ~ §§§ºss-> º 3% - º * never be kept up more than five or ten minutes at one sitting. **quires considerable force and the adhesions seem very tough and 472 DISE A SES OF JOINTS, CA. RTILA GES AND LIGA MENTs. strong, the outlook is not favorable, and after a few unsuccessful seances this form of treatment should be abandoned, as also should it be given up if after each manipulation there is a return of inflammation. This latter complication, however, is liable to follow once or twice in any case and should be prohibitory only when frequently repeated or severe. When it does occur, no further manipulation should be attempted until the parts are again free from abnormal heat. Certain varieties of stiffness can be manipulated every day or two, others may require a longer interval. Between times motion may be pre- served by means of extension, splints, or the Stromeyer screw. (Figs. 279, 280.) Movements should be kept up until the joint regains its former motions, or until no further improvement can, by this means, be obtained. Without securing motion, a fibrous ankylosis at an inconvenient angle may, by manipulation, be changed to one of more comfort or utility. Where tendons have contracted, or are in unrelieved spasm, they should be divided as a preliminary to passive motion; their division alone will accomplish little or nothing. When a joint has been extensively diseased, as in tuberculosis, manipu- lation is useless and dangerous, but where adhesions are recent it is most successful, and especially so when the trouble is mainly resident in the peri-articular structures. Where fibrous ankylosis has become very resistant and firm, nothing except the knife or chisel should be used to separate the adhesions. Bony ankylosis, if it is thought expedient or necessary, may like. wise be treated by driving a chisel or saw through the line of union if the connecting and surrounding tissues are healthy; otherwise, or when there is great displacement or deformity, excision of the joint or osteotomy of one or the other, or both of the proximate bone shafts would be preferable; more especially at the elbow, knee, and hip. Recurring ankylosis, if troublesome, may demand either division of tendons or excision of the joint. Many cases will require a brace for Some time after practical recovery, plus, perhaps, extension at night, (See Osteotomy; Excision of Joints.) LOOSE BoDIES IN JOINTs. These are not of uncommon occurrence, and consist of entirely loose or pediculated masses of varying size, which only demand attention when they impede function or cause pain. FIG. 281. They arise from : 1, condensed fibrous exudate; 2, organized blood-clot: 3, broken osteophytes, as in Osteo-arthri- tis; 4, actual foreign bodies, as bullets or needles, either encrusted or not : 5, pieces of articular cartilages, with: perhaps, sub-adjacent bone, broken of or exfoliated into the joint cavity; 6, hypertrophied and hardened portions of the synovial membrane; 7, irritative development of cartilaginous cells em. *>Nº.

In the I N J U RIES OF J O IN T S. 473 latter class, owing to severe irritation, one or more of the depots of in- active cartilage cells, which are to be found studding the deep layers of articular cartilages, take on active growth, press forward the layers of membrane between them and the joint cavity, and become prominent as minute nodules. Combined growth and the movements of the joint Soon stretch their attachments and they become pediculated, which connec- tion is apt to be snapped during some motion of the joint, and the now unattached bodies float free. Loose bodies almost never are found in other than hinge joints, and nearly always in the knee. They may be single or in great numbers, according to their mode of origin. SYMPTOMs arise when the bodies get caught between articulating sur- faces. Commonly they become so caught for a second, and at once slip out again. In either case the symptoms only vary in degree and duration. When the accident takes place the joint surfaces are forced apart and bruised or scratched, and the ligaments are put upon a severe stretch, the joint locks, and if it be the knee, the person is thrown to the ground in great agony, sick and faint. If the body slips out again, pain and other symptoms instantly cease, until the accident again takes place. Other- wise symptoms persist until relieved by the surgeon. Very rarely, a joint becomes locked in this way without pain. Any variety may be followed by synovitis, but this is not common or serious except in joints already diseased or predisposed thereto. Frequently recurring entanglement is apt, in time, to originate chronic synovitis with persistent effusion. Bodies can usually be felt beneath the joint covering, more or less defi- nitely fixed in position; but sometimes cannot be felt, or disappear from touch for a time, or upon motion of the joint, and reappear either errati- cally or upon certain motion or manipulation—as a rule, best understood by the patient himself, as, indeed, is often the best method of unlocking the joint. Contrary to the case where dislocation of joint cartilages, such as the semi-lunar, has taken place, loose bodies usually lock the articulation in anomalous positions. The history, method of occurrence, and, perhaps, palpable presence of the loose body, will furnish enough evidence for differential diagnosis. Such manipulation as each individual case, or the patient himself, may suggest, will unlock most joints. If this fail, nothing short of exploring the joint and removing the offending body will avail. Often wearing a brace or pad will prevent frequent joint-locking by securing the body in one position, or by restricting certain movements of the joint which invite the body between articulating surfaces. If the distress therefrom becomes great, the bodies should be removed Y incision. To do this it should be firmly secured before anaesthesia by Pressure of a finger or strap, or better, by transfixion with an aseptic pin or needle. If this precaution is not taken, the body will often have dis- *PPeared beyond reach into the joint when the incision is made over its former site. If the bodies are numerous, or cannot be brought near the Surface, nothing short of exploration of the joint and the removal of all Present in or around it will avail. INJURIES OF JOINTs. 92ntusions of joints call for no other treatment than rest and evaporat- ing lotions. Succeeding complications, such as inflammation or abscess, * to be treated as elsewhere described. 474 DISE A SES OF JOINTS, C A RTILA GES AND LIGA MENTs. Sprains.—Contusing injuries usually accompany or complicate sprains, which may be defined as a condition of more or less stretching, bruising, or laceration of the contents or immediate surroundings of a joint, and are always the result of forcible motion of an articulation beyond its range of function, or in a direction contrary thereto; in fact, sprains are mild varieties of dislocations. The causative force may act directly or indirectly. The hinge-joints are those usually affected. In the milder forms the sur- rounding ligaments or tendon insertions may be simply stretched, and a few vessels of, or the synovial membrane itself, be lacerated. This is fol. lowed by an intense hyperaemia of the entire joint and surroundings, especially of the subserous vessels of the synovial membrane, which often leads on to synovitis; rarely to the suppurative form and to arthritis, unless the subject is tuberculous. Swelling and Oedema quickly set in and effusion rapidly distends the joint cavity. This exudate may become plastic and even involve surrounding ligaments and tendon sheaths. Hemorrhage into the joint may take place. SYMPTOMS.—The injury is accompanied with intense sickening pain, perhaps vomiting and shock, and more or less disability, according to the extent of injury. The joint almost immediately swells and becomes hot, and soon begins to throb with dull pain. The limb will be found in that position which permits least tension in the joint. Motion is exceedingly painful, and if ligaments are extensively torn, is anomalous. If diagnosis cannot be readily made without much manipulation, anges- thesia should be induced. Differential diagnosis from fracture, even under ether, is often difficult; sometimes, as at the wrist and ankle joints, impossible. Wherever this doubt exists the case should be treated as for fracture. Strict adhesion to this rule will save many an unfortunate result. f TREATMENT.—The case seen early—within an hour or two—and diag: nosis established, a sprained joint should be plunged into either very cold or very hot water, and there allowed to remain twenty or thirty minutes, until the bloodvessels about it have thoroughly contracted. Swelling, effusion, and inflammation are thus prevented. It is then elevated and firmly bandaged from below upward. The extremity is to be kept thus bandaged and elevated for twenty-four hours, when a plaster or other snug-fitting dressing should be applied, and he may then be allowed to sit up. The cast is to be renewed as swelling goes down, and left on from one to three weeks, according to the extent of the injury. Passive motion and counter-irritation by liniments, or otherwise, may then be necessary, or a supporting brace may become advisable. ſº If, however, the sprain does not come to hand until swelling, effusion, or inflammation has set in, success with the bath will not be so marked, and hot, cold, or evaporating lotions, the ice-bag, and perhaps poultices and counter-irritation will take the place of tight bandaging until swelling goes down sufficiently to justify the plaster dressing. WOUNDS OF JOINTs. Wounds of joints are of two classes; those opening the joint through the integument, including such accidental wounds as lacerated, incised, punctured or gunshot, and the premeditated ones of the surgeon; and those attacking the articulation from beneath the integument, such as fº W O U N DS OF JOIN T S . 475 tures and dislocations. The latter class may communicate with the air and likewise become, as are all those from without, open (compound) wounds. All open wounds of joints may be, or become, septic or poisoned from outside influences; but closed joint wounds can only become infected or septic from the blood, by sloughing of their coverings, lymphatic conduc- tion, or from rupture of the deep glands of the skin. DIAGNOSIS.–Closed wounds of joints have been discussed under other headings, and need not further concern us here. Open wounds in the neighborhood of joints now have comparatively few points of diagnosis or differential diagnosis capable of puzzling the surgeon, because the very mode of treatment establishes the exact nature of the wound. That is, all wounds must be thoroughly cleansed. Hence wounds near joints are to be opened up to their bottom, if at all deep, and incidentally their nature is thus established. The danger of mistaking serious for trivial injuries until sepsis sets in is thus avoided. Joint wounds may be palpable from their extent, display of cartilage, flow of synovial fluid, or be made so by exploration. If the case is old, a wound which has entered a bursa and set up Sup- puration must not be mistaken for articular involvement. To avoid such mistakes, even in cases where there seems to exist no doubt that the joint is involved, it should not be laid open before penetration of its cavity is proved. Early reached and properly treated, uncomplicated open joint wounds should almost always progress favorably to perfect cure, with unimpaired utility. But if infection has taken place and suppuration set in, the case is one of utmost gravity. (See Acute Purulent Arthritis.) TREATMENT.-Any wound or open fracture near a joint should be re- garded with extreme care and suspicion. The surrounding parts should be cleansed and the wound then investigated. If the wound stop before entering the joint it should be cleansed, sutured, and the limb be put upon a splint until fairly healed. But if a probe or the finger carried in enters the joint, or, this failing, the wound has been laid open and proved to penetrate, the opening into the synovial cavity should be made sufficiently large to wash out the joint thoroughly with 1:1000 corrosive sublimate solution. . The articulation having been freed from foreign matter and the syno- vial membrane and integument separately sutured with chromic catgut, * dressing and splint are applied and left for three weeks, when Passive movements are to be commenced. Subsequent local or constitu- tional signs of inflammation in the joint will indicate immediate re-open- *š, Irrigation, and possibly curetting of the cavity, and the introduction of ºrubber drain-tube to the bottom of the joint. . Violent septic arthritis must be met with free incisions, curetting, wash- *g, and gauze packing of the entire joint. Or, if these measures fail, and Without resorting to them in aged or broken-down individuals, excision **mputation must immediately be performed. : "Pº", or compound dislocations are to be cleansed, reduced, the joint **ted, usually a drain-tube introduced, the synovial membrane, torn *nts, etc., sutured as far as possible into normal position and the Outer wound united. mi reduction cannot. be effected, even after free incisions have been aCie, the end of the dislocated bone must be excised. o. a splinter of an open fracture will wound a joint situated a 8 *tance from the original injury.

Proper treatment of the open fracture would, however, eliminate danger from the joint opening, but a septic condition of the fracture will almost invariably be followed by dire consequences to the knee, and perhaps kill the patient. Open and com- municating fractures involving a joint demand prompt exploration of the same, removal of fragments, blood, etc., or excision, or amputation, ac- cording to circumstances. Precisely the same is to be said for gunshot wounds involving joints; if the joint surfaces are only grooved or cracked, however, washing out and drainage will alone be required. In all cases of joint injury rest and immobilization for weeks must be insisted upon. If effusion, swelling, and disability persist after healing of a joint wound, active counter-irritation, a rubber bandage, massage, or some form of supporting apparatus must be employed. (See Chronic Arthritis, Chronic Synovitis, Ankylosis.) DISLOCATIONS. DEFINITION.—A dislocation or luxation is a violent displacement of a bone from its normal relation with another bone at the place of mutual articulation. The term dislocation is similarly applied to an intra-articular fibro-cartilage when it has been displaced from its normal position. It will be seen that I limit the term to articular displacements due to trau- matic or muscular violence, as I regard the so-called pathological or spon- taneous dislocations as mere symptoms of other diseases, generally arthritis or paralysis of muscles, and the congenital dislocations instances of malfor- mation from arrest of development or foetal disease. I admit the possi: bility of congenital dislocations being sometimes due to violence received by the foetus in utero, but such a bare supposition does not warrant the application of the term dislocation to conditions which resemble other con- genital arrests of development. The term “old” is applied to dislocations which have not been reduced for some time after their occurrence. The definition, it will be observed, is quite arbitrary and ambiguous, and no rules can be laid down to demark the exact time when an acute disloca- tion becomes one of this class. Thus a dislocated elbow is commonly spoken of as “old” when it has remained unreduced for three weeks, and a sim- ilar persisting lesion at the shoulder joint assumes the term when it has existed from four to seven months. e That bone which is more remote from the trunk is the one which is said to be dislocated. Thus dislocation at the hip is called a dislocation of the femur, not of the innominate; dislocation at the knee is termed a disloga- tion of the tibia, not of the femur; and dislocation of the ankle is de' nominated a dislocation of the tarsus. The displacement of the bone may be in various directions; thus, backward, forward, upward, down- ward, or laterally. Each joint is liable to sustain dislocation in certal" directions rather than in others, this tendency being due to the shape of the articulating surfaces and the manner of muscular and ligamentoº attachments about the joints. Dislocations at amphi-arthrodial joints, such as are found between 09" tiguous vertebral bodies, at the pubic symphysis, and between the $88. ments of the sternum, are sometimes called diastases. I prefer to Tºri" the term diastases to epiphyseal fractures, and to apply the words dislo" tion and luxation to these as to other joints. I) IS LO C A TI O N S. 477 A dislocation is complete when no portion of the articular surfaces remain in contact. Complete dislocations are rare in hinge-joints, but common in ball-and-socket articulations, Incomplete or partial disloca- tions, often called subluxations, are luxations where the displacement is not sufficiently great to cause loss of mutual contact between portions of the articular surfaces. As in fractures so in dislocations, the lesion may be complicated. Laceration of soft parts, rupture of large vessels or of nerve-trunks, fractures involving or not involving the joint-cavity, and similar accompaniments, constitute the complications that make the term complicated dislocation applicable. When an external wound leads to the seat of dislocation the injury is called an open dislocation, in con- tradistinction to one not so exposed to the entrance of air, which is a closed dislocation. The terms “compound ’’ and “simple * are as unde- sirable here as in connection with fractures, and I have accordingly employed the better terms, “open’ and “closed.” When a dislocated bone has its primary position altered by efforts at reduction, involuntary muscular action, or other cause, a consecutive or secondary dislocation is said to exist. For example, an iliac dislocation of the head of the femur may be converted into a sciatic dislocation; the latter would then be called a consecutive or secondary dislocation, the former a primitive or primary one. t - CAUSEs.-The predisposing causes of dislocation are relaxed or stretched ligaments, muscles weakened by paralysis or atrophy, old tears in the ligamentous capsule, and imperfections in the socket from either accident or disease, and such relation of the normal articular surfaces and liga- ments as will readily permit displacement. The greater the normal freedom of motion, and the more exposed the joint is to accidental blows, the greater is the tendency to suffer dislocation. Hence the prečminent frequency of luxations of the head of the humerus. Dislocations at the elbow occupy in point of frequency the position next to dislocations at the shoulder, which are the commonest of all luxations. Certain positions of the bones at the moment of receipt of injury tend to allow the occurrence of dislocation. Thus a blow on the chin is more apt to dislocate the jaw if the mouth is open at the time; so axillary luxation of the head of the humerus is more readily produced when the arm is abducted and elevated. The exciting causes of dislocations are external violence and muscular Contraction. The strength of the ligaments surrounding the joint and their disposition in relation to the direction of the applied force will often determine the direction of the dislocation and also the character of the injury; that is, whether it shall be a fracture or a dislocation, or both ; for violence will usually either break or luxate, according as the force drives the bone toward the weak or strong portions of its liga- mentous capsule. External violence may exert itself directly upon or near to a bone or joint, or indirectly as when applied at a distant point or extremity of a bone or limb, the intervening bone or bones and their attachments acting upon the principle of one or other of the classes of levers to produce the luxation. Thus a fall upon one foot whilst the body ls in an erect posture may produce a dislocation of the knee or hip, and * Case is recorded where a blow of the fist upon the upper portion of the humerus produced a dislocation of the head of that bone from its articular Savity. Likewise, twisting forces are common causes of certain disloca- º, notably those of the ankle, hip, and elbow. They are apt to occur in this manner when one portion of an extremity is held firmly whilst the other is given a rotary, lever-like motion, as when the foot is suddenly 478 DISE ASEs of Joſ NTs, C A RTIL AGES AND LIG AMENTs. caught and the whole weight of the body is thus brought to bear on the ankle-joint, dislocation will be the almost inevitable result. It is most probable that muscles frequently lend great assistance to external violence in the production of dislocations, for it is a well-known fact that men whilst intoxicated seldom sustain dislocations, and that much more force is required to produce luxations in the cadaver than in the living body. Muscular action may give rise to dislocations suddenly, as during voluntary motions or convulsive seizures of any description, or in a more gradual manner, as is witnessed in certain pathological changes in joints, or as a result, perhaps, combined with the former, of chronic contractions or con- tractures, producing the so-called “spontaneous” dislocations. These Causative factors are all accidental or pathological, but there are certain persons who, through possession of loose articulations or injury, have developed habitual dislocations, and can at will produce and likewise replace these deformities. Muscular contraction is a very important element in the study of dislocations, for it may increase displacement, render the course of the displaced bone to its present final position uncer- tain, and in some cases greatly increase the difficulty of reduction. Dis- tention of joints by fluid renders their bony elements peculiarly liable to displacement by either muscular or traumatic action. Fracture or unequal growth of one of two parallel bones renders joints situated at their ex- tremities prone to luxation, or even may directly cause that accident. PATHOLOGY..—The pathology of dislocations is of great interest. In incomplete dislocations little change is to be noted; the ligaments are stretched but not usually torn and ecchymoses may be present in and about the joint, but seldom does any momentous damage or impairment of func- tion result. Complete dislocations, on the other hand, nearly always pre- sent tearing of ligaments, surrounding tendons, and muscular attachments, particularly those having origin from or insertion into the capsule itself. If the dislocation be typical there is apt to be quite limited tearing of liga- ments, but where extensive laceration has taken place the resulting de- formity will usually be irregular. The capsule of a dislocated joint need not of necessity be ruptured, but may be entirely stripped from its bony attach- ments. In complete luxations of hinge-joints the ligaments are frequently merely stretched, but such displacements of ball-and-socket articulations are always attended with laceration of the capsule. This rent most fre- quently consists of a linear slit through which the head of the bone has been shot. It is situated, as a rule, near the rim of the glenoid cavity in the shoulder and in the hip at the acetabular edge. A knowledge of the probable location of this rent is of utmost importance in reduction. The luxated bones are apt to render more or less damage to sur- rounding structures, and muscles, nerves, arteries, fascia and skin, either or all, may sustain injury thereby. They may be stretched, bruised, or torn, the latter, in cases of arteries such as the popliteal at the knee or the axillary at the shoulder, being most formidable complications. Modern surgery has rendered open dislocations, as those involving com- municating lesion of the skin or mucous membrane, of practically the same pathological significance as the closed variety. In voluntary muscular, also in certain pathological dislocations, the ligaments are simply stretched and surrounding structures are not of necessity injured: If the joint is quickly restored to its normal relations by reduction and maintained at rest for the requisite time, the injured ligaments and other structures quickly regain their normal condition, although the joint may always be weak and more liable to future displacement than before it DISL O C A TI O N S. 479 received the primary injury. If, on the contrary, the dislocated bone remains in its new and unnatural situation a remarkable series of phe- nomena take place.

The dislodged head of the bone meanwhile has created a new socket or cup-shaped depression for itself by pressure, atrophy and condensation of the struc- tures upon which it rests. The new socket will, in time, have raised edges, be lined with eburnated bone-like or fibrous material, which some. times becomes covered with a membrane resembling true joint or synovial membrane, which secretes a lubricating fluid having many of the physical attributes of true synovial secretion. A species of capsule may even envelop the new joint in course of time. The head of the bone usually undergoes some flattening and atrophy, but may remain un- changed. The formation of a new joint is rapid in children but occupies years for its completion in any save the most youthful adults. By these natural resources very fair function of a limb may be regained, even if the luxation continue unreduced and unsightly deformity remains. The pathological significance of inflammation about dislocations is very great, for by its means vessels and nerves are apt to form adhesions to the dis- placed bone extremity, which may give rise to rupture of those structures when attempts are made at reduction. Inflammation and its effects may also permanently ankylose a joint which has been dislocated, or may even, in predisposed individuals, give rise to purulent arthritis. SYMPTOMS.—The principal symptoms of dislocation are: 1. Deformity. (a) Absence of a known prominence. (b) Unnatural presence or disappearance of a depression. (c) Changes in length, axis, and general conformation. (d) Swelling. . Rigidity. . Absence of crepitus. . Pain. 5. Force not generally required to maintain in position after reduction. The diagnosis and differential diagnosis of luxations cannot be made out with a single sign; sometimes it is impossible, even to the most expe- rienced, when all available diagnostic resources are brought into requisi- tion. In this section it is proposed to describe principally typical disloca- tions, and not to enter upon their differential diagnosis, as that has already been elaborated under Fractures. Deformity, more or less marked, is an inevitable accompaniment and sign of dislocation. The bones entering the structure of a joint are dis. placed, and hence it is impossible that its contour and appearances should not be changed. The position of these separated joint elements is usually the same and typical for the same dislocation. The absence of one ele- ment of an articulation is noted, and an unnatural prominence has made its appearance in the vicinity of the joint, the axes of the bones are changed from that of their normal relation to each other, and there have occurred various other changes, as in the length and circumference of the limb. Certain attitudes, which will be described under Special Disloca- tions, are significant of particular dislocations. The swelling which is apt rapidly to supervene when displacement has occurred is not usually so great as to prohibit diagnosis, although not in- frequently this symptom may entirely mask the true mature of the injury. Strong pressure with the fingers or hand, or an elastic bandage for a few moments, may so dissipate infiltration that salient prominences and lººk marks, or even all portions of the affected bones, may be made out. This failing, the judicious use of a well-tempered exploring needle may determinº : DIS LO C A TI O N S . 481 relative positions. When swelling has come on with great rapidity, and circulation has ceased in the distal distribution, rupture of the main artery most probably has complicated the original injury. Preternatural rigidity or loss of function also usually accompanies dislocation. Separated joint surfaces, as a rule, have the same relation to each other in the same dis- location, and are held firmly and rigidly in that position unless great laceration of ligaments or profound shock also be present, when the con- trary, or even extreme mobility, may substitute this symptom. Immo- bility is rarely absolute, and some degree of motion can usually be elicited, which is limited by a more or less elastic check imparted by the remaining portions of ligaments and the resistance of soft parts surrounding the dislocated bone. If the injury is also associated with fracture, rigidity will not usually be present. Utmost caution must be used in diagnosing dislocations, in patients whose age permits the possibility of epiphyseal fractures, to distinguish the former from the latter, as both possess points of great resemblance. The corresponding bones, joints, and regions of both the injured and sound side of the body should always be compared, and the two hands made to examine synchronously and contrast the corresponding depres- sions, prominences, and “landmarks” of the two sides. If this be made a rule of practice and procedure, many an incorrect diagnosis arising from inappreciation of the peculiar topography of the patient under considera- tion will be avoided, and still other cases will thus be quickly robbed of their diagnostic difficulties. True crepitus cannot be developed in a case of dislocation unaccom- panied by fracture, but it is likewise true that this sign cannot be devel- oped in every case of fracture. Often a friction sound or sense can be perceived in dislocations, which is developed when compressed fibrous or muscular tissues and the displaced bone are moved upon each other, and the simple movement of dry or otherwise altered synovial membranes is quite sufficient to produce this “false crepitus.” This symptom is unusual in Very recent luxations, and does not often make its appearance until One or more days have elapsed since the occurrence of injury; but fric- tion of a torn ligament may give rise to it at any period of the case. Dislocation crepitus is much more obscure than is that of fracture, unless the latter happen to be deeply situated or when inflammation has caused softening of the disrupted surfaces. A dislocation complicated by a small fracture, as of a chip from an acetabular rim or a torn-off tuberosity, may Present, either or both forms of crepitus. Such injuries are often impos- sible of more exact diagnosis than supposition. Pain in dislocations is frequently more unbearable, and of a dull throbbing or stretching and tearing variety than is the case with that of factures. If nerves have been pressed upon or torn, tingling, numb- *; or anaesthesia and paralysis of their distributions will be tempo- *ily or permanently present, according to the degree of nerve injury *stained., Muscles are placed upon the stretch, and the bone extremity * Probably pressing powerfully upon surrounding structures—an aggré- gº of causes quite sufficient to account for the very marked subjective ºptoms of which cases of dislocation so often pathetically complain.

It *...* act that dislocations when reduced customarily remain in position, but the contrary is as often true if there has been great laceration of liga- 31 482 DISE A SES OF JOINTS, C A RTILA GES AND LIG AMENTs. ments or soft parts, whilst many fractures, notably certain ones about the wrist, will retain their position perfectly when set or reduced. Open or compound dislocations present very little difficulty in diagnosis, for their character is easily cleared up by the opportunity for direct ex. amination which is afforded during the necessary process of treatment. Luxations complicated by fracture have been discussed under the latter heading. They are injuries of much gravity as regards diagnosis, treat- ment, and prognosis. PROGNOSIS.—The general prognosis of a given dislocation is favorable or unfavorable in direct ratio to its complications. Simple luxations promptly and completely reduced and kept at rest for the requisite length of time practically never of themselves endanger life, limb, or function; the slit in the capsule firmly heals, the displaced surrounding tissues quickly return to their former condition, and little save some swelling and perhaps Some pain and stiffness remains to remind the patient of his recent accident. But this pain and stiffness—usually the result of the necessary immobiliza- tion of the joint to insure healing of the torn structures—may continue for a long time-or even in exceptional instances lead to permanent disability. Some weakness or atrophy may also follow simple displacements; this prob- ably being due not only to inaction of the muscles but also in part to stretch- ing or bruising of the proximate nerves or muscles. Atmospheric changes are apt to have a forecast in the painful stiffness which the injured parts may assume before a change of weather, for perhaps even years after dis- location. Much also, in all forms of dislocations, depends upon the par- ticular joint involved, the degree of the displacement, the condition of health and the reparative powers of the individual, the means employed for reduction, and the time after accident when treatment was instituted, Thorough reduction may be rendered impossible by a portion of liga. ment or muscle occupying the joint cavity, and preventing the replace- ment or retention of the dislocated bone. Secondary or recurrent dislocations are rarely of special danger, but the prospects of permanent cure are extremely slight. When luxations are complicated by rupture of the main artery of an extremity the prognosis becomes most grave, and loss of the limb or even of life is the common result. Torn nerves, muscles, or tendons are not of such serious import, as they can often be restored to functional activity by operation. Open dislocations have been robbed of most of their former terrors and dangers by modern wound treatment, but they will always be much more serious injuries than simple luxations, from their liability to become in- fected. If they can be guarded from this latter complication the chances of saving the joint and ultimately restoring it to usefulness are very good. Old dislocations or recent ones, which it is found impossible to reduce, are not to be prognosticated so unfavorably as might at first sight seem necessary, for often by the formation of false sockets and articulations much of the functional activity of a limb may be restored, which use: fulness is prone to increase, not to decrease as time goes on. But, un- fortunately, pressure exerted by the bone in its new location may cause much distress or danger. The degree of disability in these ancient dis’ locations will depend largely upon the nature of the joint involved. Thus ball-and-socket joints when unreduced give rise to much less interference with function than do similar conditions in hinge joints, and even one variety of dislocation may give rise to less disability than another at the same articulation. Thus, deformity is much less in a sciatic dislocation at the hip or a subglenoid at the shoulder than is the deformity resulting D ISL O C A TION S, 483 from other dislocations of the corresponding bones. Attempts to reduce old dislocations are always serious undertakings, from the danger of rup- turing arteries which may, through inflammatory action, have become attached to the displaced bone or its fibrous surroundings. Especially is this danger salient in old luxations of the humerus. TREATMENT.-Spontaneous reduction occasionally takes place, more especially in partial luxations and in those of the shoulder. This desid- eratum may be brought about by movement during sleep, falls, or after unsuccessful attempts at reduction have failed of their purpose, but have so broken up adhesions that the force of muscular contraction or volun- tary motion afterward draws the displaced bone into position. Except in certain complicated cases, treatment of acute dislocations should always be instituted at the earliest possible opportunity, and the earlier reduction is attempted just so much more readily can it be attained. There is often a period lasting a short time after the accident during which the muscles have not begun to contract, and at this time some dis- locations are most readily reduced. The writer once had opportunity to prove this assertion in the case of a fellow swimmer who sustained a sub- coracoid dislocation of the humerus by his arm being forced upward and outward in striking the water whilst diving. It was reduced with utmost ease by manipulation before more than one or at most two minutes had elapsed. No especial care was taken of this member afterward, but dislo- cation never recurred. The indications for treatment are: 1, to reduce the dislocations; 2, to secure firm repair without inflammation, and 3, to restore function. Reduction is to be accomplished by constitutional relaxing measures, and by manipulation. Mechanical force is never required or permissible in recent luxations. Prolonged painful efforts to reduce a dislocation should never be made, and relaxation by ether should be secured in all rigid dislocations of the larger joints; also in case of any joint should it resist our first few efforts or give rise to excessive pain upon motion. The primary stage of ether, or some abrupt question or accusation put to the patient, may occasionally direct attention from the injured parts and permit the surrounding muscle to be surprised and the joint reduced by a rapid manipulation, but, usually, an- *sthesia to the stage of profound relaxation FIG. 285. must be attained before manipulation can properly be applied and reduction effected. Reduction made without the addition of mechanical force to the ordinary powers of the surgeon constitutes replacement by ma- nipulation, which method is always prefer- able to any other. But in certain cases the hands of an assistant may be addi. tionally employed or a better hold upon the part obtained by wrapping it in cloths, ºr by throwing a “clove hitch” or noosé knºt above some bony prominence, which Will prevent slipping or damage by traction upon Soft parts. The object of manipulation is to secure through one or more consecutive Pºsses of extension and counter-extension, rotation, pressure, adduction, *duction, flexion or extension, the replacement of the dislocated bone. Y these processes relaxation of some structures and tension of others is 484 DISE A SES OF JOINTS, CARTILA GES AND LIG AMENTs. attained which either assist, permit others to assist, or are prevented from hindering the return of the bone to its socket by the route of exit. From this it will be seen that to reduce luxations by manipulation an accurate comprehension of the mechanism of dislocations must be possessed by the surgeon who may be called upon to replace them.

Noose knot. persisted in may often accomplish reduction in the hands of ignorant per- sons, but exact anatomical knowledge is vastly safer, more satisfactory, and successful. The surgeon should be familiar with those motions best calculated to relax the bone capsule, or to remove other obstructions, and to bring into play such muscles or ligaments as will assist him in his en- deavors to replace the bone. Sometimes a rocking motion combined with manipulation will insinuate an obstinate bone into its proper position. Manipulation to prove successful must be applied systematically, and the sequence of its various objects must follow in regular order. Thus, obstructive tension is first to be overcome. Then the bone is to be dislodged and gotten opposite the capsule rent and finally forced into pºsiº tion; which last two procedures are often accomplished through making portions of ligaments, etc., act as pulleys or levers. As the capsule rent is made by pressure of the head of a bone, hence the lesion is always in the direction of dislocation, and the rule is always, if possible, to return the bone in the exact direction of dislocation. If only a slit exists in the capsule that ligament must be relaxed to permit reduction, but unless * flap has been torn from one edge the capsule will never prevent reduction D IS I, O C A TI O N S. 485 by occupying the normal position of the displaced bone. The existence of an obstructive flap is an extremely unfortunate occurrence, and one which nothing short of an operation will relieve in some cases. Reduc- tion will sometimes be further obstructed by muscles or tendons slipping over or under the dislocated head. For these complications, as when the metacarpal bone of the thumb slips under a head of the flexor tendon, nothing short of division of the restricting band will suffice, that the reduction may be completed. If swelling interferes with reduction we should be content to wait until it in part or wholly subsides. This takes place with rapidity, and little is lost by the pursuance of such a course. But cases will occasionally be encountered in which manipulation will fail, or where anaesthesia is refused or inadmissible, and to these we will be driven to apply the application of force. This agent is brought into action by means of extension and counter-extension, energetic rotation, and by direct or indirect pressure, or one or all of these measures in con- nection with manipulation. The required force must gain access to the limb through certain mechanical attachments. If bandages or cloths are used for this purpose they should previously be moistened, for in that con- dition they are less liable to slip. Clove hitches, noose knots, elastic bands, or the metal attachment plates of Lewis, which are shown under Refracture of Deformed Union. After Fracture, can be used for this purpose. Great caution must be observed that pressure or traction be not made upon the skin or soft parts, but that bone extremities are made the points of resistance. By these means in- definite extension and power, limited only by the strength of the distal bone, may be secured. Forcible reduction should be made to simulate the motions of manipulation as nearly as possible; but if this cannot be attained then the force should be applied in the direction which will bring the head of the bone directly to the socket, or to such proximity to it that lateral pressure or rotation will complete the reduction. . The power must be applied gradually, steadily, and with the greatest judgment; a rocking motion may be superadded at times with benefit to force the dislocated bone from entanglements, or by chance to slip it into the socket. Gradual continuous extension by elastic bands or weights acting over a pulley often proves of great utility. Up to fifty, or more, pounds of Weight may thus be employed, but it will be found that lesser weights ºcting for a long time will accomplish more than will greater amounts for a shorter time. Compound and other pulleys, until recently so much in Vogue, are to be unequivocally condemned for recent luxations, and only most rarely can there ever arise necessity or indications for them in ºny form of dislocation. Anaesthesia is as beneficial and requisite during the Reduction of displacements by forcible means as in manipulation. Force is to be applied as follows: 1. The power is to be exerted in a Pºoper direction. 2. It must not be applied in a spasmodic or violent manner, but continuously, and with a gradual increase of amount. 3. The P* must be rotated and rocked in all directions to free the head of i. ‘. º ºntanglement or adhesions. 4. When resistance of muscles the l A sufficiently overcome to permit the head of the bone to reach **Vºl ºf the cavity from which it has been replaced, an adroit move- * of the part must be made by the hands of the surgeon toward that cavity, whilst at the same instant the extending force should be relaxed Y an aSSistant. 486 DISE A SES OF JOINTS, CARTIL AGES AND LIGA MENTs. Should even these measures fail, then will arise the advisability of insti. tuting such operative measures as subcutaneous or open division of the restricting tissues, or even of the neck of the dislocated bone itself; the excision of its head or of the whole joint, or, finally, of amputation. A dislocation is known to have been reduced when the articulation assumes its normal contour and functions, and by the direction of the axis of the limb or the elements of the joint. The fact is frequently an- nounced by the before-mentioned moist or muffled snap. The dangers incident to the application of force are proportionate to the presence and mature of adhesions, and to the amount applied. After being reduced the joint must be kept at rest by means of splints, bandages, or apparatus for a few days or weeks, according to the severity of the dislocation, the joint involved and the nature of complications. At the expiration of this time passive motion is begun, and shortly afterward active movements, or customary occupations, may be resumed. But movements in the direction of the former capsule tear should be avoided for as long a time as possible. If these precautions are not con- sidered the risk of recurrence or of establishing an “habitual dislocation” becomes very great. Electricity, massage, hot and cold douches, and injections of Strychnia will prove of benefit if muscles have lost their power. Should inflammatory reaction occur its symptoms are to be met with the usual means. Treatment of Old Dislocations. Much that has already been said applies equally to the treatment of old dislocations. For reasons already stated it is justifiable to make judicious attempt at reduction of any dislocation, no matter what may be its age. In this variety of dislocation passive motion, poulticing, massage and extension should be kept up for days or weeks before an attempt at reduction should be undertaken. Any restricting tissues should be divided some time previously. Manipulation, even if it does not accomplish its ulterior object, frequently gives the patient a wider range and ability of motion than he had before. Attempts to break up or reduce old dislocations are always to be undertaken with the full knowledge of both surgeon and patient of the great risks to be encoun- tered in all such operations. The most common accidents attending the modern reduction of old dis- locations are rupture of vessels and nerves, fracture, and rendering the injury open or compound by giving way of the skin. Rupture of vessels is almost exclusively limited to arteries, and of the latter, principally to the axillary, and are most fatal accidents under any form of treatment. Their occurrence is recognized by the sudden formation of a pulsating tumor in the neighborhood of the old injury. Exceptionally the artery does not rupture until several days after the attempt at reduction, or ºn aneurism may form either with rapidity or otherwise. Gangrene of the limb may follow pressure upon or laceration of vessels. Fracture, if it take place close to the dislocated head may prove of more benefit than injury by forming an artificial joint and save subsequent recourse to operation for the same purpose. Recoveries have taken place in all varieties of these accidents. Torturing neuralgia, persistent odema, aneurism, varix and gangrene are possible sequelae of unreduced luxations or of efforts made for their relief. & The treatment of open or compound dislocations has been discussed under Wounds of Joints. S PEC I A L ID IS LO C A TI O N S. 487 SPECIAL DISLOCATIONS. Dislocations of the Vertebrae. Dislocations of the vertebrae unaccompanied by fracture are injuries of rarity. The ultimate effect of almost all casualties of this mature is lethal; most commonly immediately, but exceptionally death is postponed for months. Some cases recover. The seat of lesion is most commonly in the cervical region, less frequently in the dorsal, and never, so far as surgical history goes, in the lumbar region. The most common disloca- tion is that of the axis. The cervical region is predisposed to these acci- dents because of its range of motion and freeness of articulation. Most dislocations of the cervical spine are simple or uncomplicated, but may be complete or incomplete. The region bounded by the fourth and sixth vertebrae is most vulnerable. Any variety of displacement may injure the cord, rupture its vessels, or give rise to subsequent inflamma- tion or effusion. The treatment of spinal dislocations consists of reduction, if feasible, and subsequent care of bladder, rectum, and surfaces exposed to pressure, as in fracture complicated by cord injury. The water or air-bed and extreme cleanliness will likewise be found of great utility to prevent pressure necrosis. Dislocations of the Cervical Vertebrae. Dislocations below the axis are usually forward; that is, all the vertebrae above the seat of displacement are thrown forward, but lateral or rotary dislocations are not unknown in FIG. 288. this region. These luxations are caused by indirect violence bending or twist- ing theneck. If complete, the pos- terior common vertebral, also the lateral, ligaments are torn.

(BRYANT.) 488 DISE A SES OF JOINTS, C A RTIL AGES AND LIG AMENTs, cases exact diagnosis is very difficult in dislocations of the cervical spine, The head is bent rigidly on the breast in forward, and in the opposite direction in backward dislocations. A prominence or depression, accord. ing to the direction of the dislocation, may sometimes be noted by a finger carried into the pharynx. If the injury be above the origin of the phrenic nerves, death is usually instantaneous. Treatment consists of extension by hands placed upon the chin and occiput and counter-extension by pulling upon the patient's feet; or by means of a folded sheet drawn over the shoulders combined with manip. ulations calculated to disengage the luxated vertebrae, and direct pressure applied at the same time to the neck and, perhaps, through the pharynx. Atlo-aavoid Dislocations. Alto-axoid dislocations come next in order of frequency. Three varie- ties exist: the odontoid process of the axis may be fractured and thus permit dislocation of that vertebra backward and crushing of the cord; the odontoid ligament or some fibres of its transverse portion may be torm and permit the odontoid process of the axis to slip beneath it; or the atlas may be rotated upon the axis until the articular ligaments rupture and permit the former bone to rest obliquely upon the latter. These lesions result from force applied to the head, from falls, blows, and twists; whilst the presence of vertebral caries greatly predisposes to them. The symptoms and consequently the exact diagnosis of these, as of other cervical dislocations, are vague and unsatisfactory. They usually prove rapidly fatal, and great precaution must be observed in the treatment, as instant death is liable to follow even trivial attempts at reduction, from injury to the cord by pressure from the odontoid process. Nevertheless, it is our duty to attempt such reduction by traction (as above) in the line of the spinal column, manipulation, and direct pressure. If success attends the surgeon’s efforts care must be taken to retain the head in the proper position by pillows or other means. Occipito-atloid Dislocations. Occipito-altoid dislocations are occurrences of great rarity and fatality, being due to great violence tearing the condyles of the occipital bone from the articulating cavities of the atlas. - Dislocations of the Dorsal Vertebrae. Dislocations of the dorsal vertebrae occur, but usually are accompanied by fracture, because of the great force required to lacerate the powerful ligaments and joints which are to be found in that region. They alº caused by violent flexioms or rotations of the body. The diagnosis is self. evident and precisely similar to that of fracture in the same region, and treatment consists of application of the same measures as for other Yeº tebral displacements, except that continuous extension and counter-exten- sion should form a more prominent feature of after-treatment. Dislocations of the lumbar region without fracture are unknown. They require no separate consideration. SPECIAL DIS LOC ATION S. 489 Dislocations of the Ribs from the Vertebral Column. A few cases of this variety of injury appear in surgical history of times now remote; none have been recorded during the past forty-four years. They, as a rule, accompany terrific lethal traumata. Diagnosis is made by the absence of the head of the rib from its vertebral socket, and treatment is to be supplied by a broad band highly encircling the chest. Dislocations of the Coccya. These unusual injuries take place principally in women, resulting from falls, kicks, or other direct violence, or during parturient efforts. Three varieties have been observed : forward, which is most frequent, backward, and lateral. The symptoms of the accident are great pain, swelling over the region, and rectal examination discloses the displace- ment and its variety. The forward luxation is to be reduced by hooking the finger over it in the rectum and drawing it downward into position. Beyond manipula- tion and pressure, no definite rules can be given for treating this form of luxation. Instant relief follows replacement, but recurrence is probable. Old or inveterate dislocations may demand excision of the affected parts. (See Excision of Joints.) Dislocations of the Jaw. This dislocation occurs in four per cent. of all luxations. It may be partial, bilateral, or unilateral. A shallow gelnoid fossa and lax articular ligaments predispose to the injury; whilst yawning, laughing, sneezing, blows, and falls are exciting causes. Attempts to separate the jaws ex- cessively, or blows upon the chin whilst the mouth is open, are prolific causes of luxation. The mechanism of this dislocation is brought about by the internal pterygoid muscles becoming a fulcrum, and the muscles inserted into the chin becoming, as it were, the long arm of a lever, which, with the assist- ance of the external pterygoids, cause the condyles of the jaw to press upon and rupture the capsular ligaments, and spring in front of the articu- lar eminences, when contraction of the masseter and temporal muscles draws them forcibly upward until they are arrested by the zygomatic * and the typical deformity is produced. Rarely the capsule is not Ol' D. The symptoms are wide separation and firm fixation of the lower jaw; * Vacuity is noticed in front of the ear, and the condyles may be felt beneath the zygoma. * . A backward dislocation has been described in which the condyles are violently forced through the anterior wall of the auditory canal. Anaes- thesia is not required in the treatment of this dislocation, which consists * the surgeon carefully protecting his thumbs with strips of bandages, and then with them pressing downward upon the last molar tooth upon each side of the jaw, whilst, at the same time, the palms and fingers grasp *ch side of the maxilla externally and press it backward. By these *nºuyres the process of dislocation is exactly reversed; tension of the * Pterygoid and masseters is overcome by the downward pressure; the condyles are pressed backward into position, and, upon releasing the 490 DISE ASE'S OF JOINTs, CA RTIL AGES AND L I GAMENTs, pressure, are drawn with great force into position by contraction of the temporal and masseter muscles. If the surgeon's fingers are not pro- tected or removed to the side of the teeth quickly, they are liable to be injured from the force with which the molars are drawn together. FIG. 290.

Old maxillary dislocations are to be treated as acute ones first, and, this failing, the forcing apart of the posterior portions of the jaw by levers or Stromeyer's forceps, or even the excision of the condyles, is permissible. After reduction the jaw must be kept immobilized for at least & week by means of a Barton or similar bandage, and the patient fed principally upon liquids.

Dislocations of the Sternum. This dislocation is unusual and, from the violent nature of the force required to produce it, has proved fatal in almost 50 per cent. of cases in which it has occurred. Direct force is the usual cause. Reduction is impossible in most cases, but, if the patient survive the complications he is not, as a rule, incommoded by the resulting deformity. Extension of the chest by bending the dorsal spine over a block of wood or round pillow together with manipulation and moulding may be tried, and should they prove successful a broad bandage must highly encircle the chest for Some weeks subsequently. Anaesthesia will favor replacement. Dislocations of the Clavicle. I shall speak of luxations of the outer end of the clavicle as disloca- tions of the scapula. Dislocations of the clavicle occur at the sterno-clavicular articulation in either a forward, backward, or upward direction. Dislocation at this joint is favored by a shallow glenoid cavity and by the great range of shoulder motions, FIG. 294. which indirectly affect the clavicular ar- -- ticulation. The disarticulation may be complete or incomplete. Hypertrophied or violent movements of the shoulder are the most universal Cause, but slow dislocation may result from nature of occupation stretching the retaining liga- ments.

The head of the bone may be excised if it produces dan- gerous or painful pressure symptoms. In reduction the shoulder must be drawn outward and forward in forward dislocations; outward and back- ward in backward, and upward, or upward and outward, in upward dislocations. By these shoulder manipulations in all three varieties the dislocated head is coaxed to the margin of its socket, when direct FIG. 295. Dislocation upward of the sternal end of the clavicle. (R. W. SMITH.) pressure and moulding are applied, and the process is restored to its normal position. When reduced it must if possible be supported for four weeks by means of bandages (such as the Velpeau) and pads, or by a spring truss or other form of mechanism. Pressure must be exerted in the direction of the articulating cavity. Fractured clavicle position in bed, in addition to the above means, yields the best results. Backward displacements always prove the most tractable. Dislocations of the Scapula. These displacements are usually called dislocations of the acromial end of the clavicle, but in accordance with the rule that the distal bone is the one dislocated, they are here termed dislocations of the scapula. As in the case with most luxations they may be complete or incomplete. When com- plete the dislocations of the scapula may be sub-, supra-, or post-clavicular. Their general causes are direct violence to the shoulder or muscular effort. When scapular dislocations are complete not only are the ligaments of the scapulo-clavicular joint ruptured, but also often portions or the whole extent of the conoid and trapezoid are torn. Subclavicular dislocations are recognized by the elevated acromial end of the clavicle and the partial rotation of the inferior angle of the scapula toward the spine, which latter symptom is due to the dragging weight of the arm. There is marked local pain, and the attitude attributed to frac: ture of the outer end of the clavicle is, in these cases, likewise assumed. Treatment consists of upward, or upward and outward, or backward SPECIA L DISL O C A TI O N S. 493 movements of the shoulder, together with direct pressure and moulding. In doing this the arm should be kept in contact with the patient's chest. whilst upward pressure is made upon the elbow. FIG. 296. Retention of the injured parts is difficult. A Velpeau or similar bandage or apparatus, or a broad strip of adhesive plaster carried beneath the elbow, up both sides of the arm, made to cross over the acromial end of the clavicle and secured upon the chest, back and front, must be worn, preferably in con- junction with the dorsal position in bed, for a month. Supraclavicular dislocations present the acromion raised whilst the clavicle can be traced to a certain point beneath, when it disappears to palpation. Reduction of this variety is to be accomplished by downward Subclavicular dislocation of and backward traction upon the shoulder, scapula. (BRY ANT.) whilst the arm is kept parallel to the trunk, and counter-extension is exerted by traction upon a sheet wound around the chest. º: Post-clavicular dislocation has only twice been observed in surgical history. It is to be recognized by the position of the clavicle directly in front of the acromial process of the scapula. A mingling of various shoulder motions and manipulation would probably reduce the displace- ment. After-treatment would be the same as for the previous varieties. Dislocations of the Humerus. These are the most common of all the dislocations, a fact readily ex- plained by the shallowness of the glenoid cavity, the lax capsular ligament, and by the great range of motion and liability of the shoulder to direct or transmitted traumata. Middle life is the most common time of occur- rence, and the accident is rare at its extremes. Dislocations of the humerus group themselves into three principal Varieties, which, in order of frequency, are: 1. Downward and some- What inward, or subglenoid, often termed axillary. 2. Forward, which embraces two sub-varieties, the subcoracoid and subclavicular. 3. Back- Ward or subspinous. Other technical or irregular dislocations also have taken place, but possess no clinical importance. Direct or, most commonly, indirect violence is the exciting cause of dislocation at this joint. Thus, waggons passing over the shoulder and fist blows upon the arm have produced it, but in vastly more instances the head is exarticulated by force employing the arm as a lever. Downward or Subglenoid Dislocations. In downward dislocation of the humerus the capsular ligament is torn *xtensively upon its lower surface, the head of the bone occupies a posi- "on upon the anterior surface of the scapula immediately beneath or, Perhaps, beneath and a little to the inner side of the glenoid cavity, where * is held between the tendons of the triceps and subscapularis muscles. 494 DISE ASES OF JOINTS, C A RTILA GES AND LIGA MENTS The axillary contents are compressed and the circumflex nerve may be so stretched or torn as to result in permanent paralysis of the deltoid.

TREATMENT.—The anaesthetic state to the point of muscular relaxation should, as a rule, be secured before attempts at replacement are undertaken. Reduction is always to be accomplished by manipulation if possible, and it will be found an exceedingly unusual dislocation of the humerus that FIG. 304. -- “\\\\\ > .

In using this method the governing principles Which have been already set forth are to be employed for the various humeral dislocations as follows: For the subglenoid variety the forearm is flexed upon the arm to relax the long head of the biceps. The elbow 32 498 DISE ASES OF JOINTS, C A RTIL AGES AND LIG AMENTS, is then grasped, and the arm raised by abduction to the side of the patient's head to relax the deltoid and supraspinous muscles. Now the forearm is supinated to relax further the long head of the biceps. Whilst the arm is held in this position by one hand the surgeon places his other upon the prominent humeral head in the axilla, and as the arm is drawn outward to a right angle with the body, lifts the head into its socket. Subcoracoid and subclavicular dislocations are reduced in a similar manner, save that after elevation the arm is to be rotated outward before being carried down, that the spinati and teres minor muscles may be still further relaxed. In dealing with the subspinous variety the arm after being carried by extreme abduction to the side of the head is rotated inward to relax the subscapularis, when the bone may easily be replaced by direct pressure from the fingers during adduction. Manipulation failing, the elbow should be grasped and drawn forcibly upward, while at the same time downward pressure is made upon the shoulder by the other hand. Next the surgeon may stand behind the patient's couch, place his foot upon the shoulder, and make rocking to-and-fro traction and rotation. If even after this manoeuvre the dislocation persist, the surgeon must place his unbooted foot in the axilla for counter-extension and make forcible traction upon the arm. Other methods of reduction are: by right angle traction, using for counter-extension either the bootless foot upon the chest-wall, or a sheet wound around from the opposite side; by bending the arm down over the knee acting as a fulcrum in the axilla; FIG, 305. by placing an air-bag or other pad in arºsa the axilla and bandaging the lower #º arm as closely to the side as possible, }\ which has proved successful, if kept up for days, even in seemingly hopeless, acute, or ancient cases; and lastly by force in the direction opposite to that of displacement. After replacement the arm must be kept in a Velpeau or other similar bandage for a week, and great care must be exercised in its use for a much longer period. Treatment of old humeral disloca- tions is always attended by great danger of serious accident. Unless contra-indi, cated by the history, a luxation of the humerus is scarcely ever too old to try reduction upon. But if the history indicates great inflammation and the likelihood of arterio-venous adhesions, the deformity had best be let alone or Reduction by knee in axilla. (Cooper.) treated by other means than reduction. - If determined upon, reduction must be attempted by separation of adhesions repeated a number of timº before the final operation, when manipulation and force are employed. This failing, if the deformity justitifies so severe a measure, the neck of the bone may be sawn through, and a false joint established, or its head exsected. Various accidents frequently occur during forcible treatment S P E CIA.

(CoopFR.) probably the rapidly formed tumor in the axilla will have pulsation and bruit. Tumors appearing in the axilla at any time after a dislocation of the humerus should excite suspicion and always be auscultated before any operation upon them is undertaken. Only general principles can be given for the treatment of these accidents. If the artery be torn, ligation of the subclavian or pressure thereupon whilst the tumor is slit open and the torn ends each secured, is recommended. Venous rupture can be dealt with in the same manner, or, if possible, by simple pressure. Rup- ture of nerves may be repaired by their secondary suture. Fractures and ruptures of muscles often prove advantageous from the subsequent relaxa- tion and formation of an artificial or false joint, but motion after fracture must be very guarded lest the vessels be torn by sharp edges or spicules— a far from imaginary danger. - Conjoint Dislocations of Radius and Ulma. Conjoint dislocations of the radius and ulna take place at the elbow, and in either of four directions: backward, forward, inward, and outward (or laterally). The backward dislocation is much the more common, usually being produced by indirect violence acting through the forearm When the elbow is extended. The bones are thrown in various positions under and behind the condyles of the humerus, and further drawn up by action of the triceps. The capsule is torn and the arm rigidly flexed at about a right angle, although occasionally some flexion and extension, or $Yen lateral motion, may be present. The forearm is shortened and the biceps and brachialis anticus are very tense. Great pain is apt to follow any motion. Usually the diagnosis is palpably evident, but in case of doubt anaes- thesia will quickly make it certain as well as allow thorough replacement. 500 DISE ASES OF JOINTs, CARTILA GES AND LIGA MENTs.

(HAMILTON.) S P E CIA 11 D IS LO C. A. TI O N S. 501 Dislocations of the Radius and Ulma Forward. Dislocations of the radius and ulna forward are unusual without frac- ture, being produced by direct violence. The forearm is supinated and lengthened, and at a right angle with the arm. Treatment consists of forced flexion and extension, and counter-exten- sion, or flex and press down upon the forearm. Lateral displacements of the radius and ulna are rarely complete. They are unmistakable and treated by moderate extension and direct pressure. Divergent Dislocations of the Radius and Ulna. Divergent dislocations of the radius and ulna occur, but are very rare. The bones are both dislocated but do not accompany each other. There are two varieties, the antero-posterior in which the ulna is thrown behind the humerus and the radius in front, and the transverse where the ulna is displaced to the inner side behind the epitrochlea and the radius to the opposite side of the humeral condyles. They are to be diagnosed and treated upon general principles. Dislocations of the Radius. In luxations of this character the head of the radius is thrown from its annular ligament and socket, either forward, outward, or backward. The former direction is taken most frequently. The head is absent from its FIG. 310. Backward dislocation of the head of the radius. (GRoss.) FIG. 311. Forward dislocation of the head of the radius. (GRoss.) normal position and present in a new locality, but the other bones of the elbow are in proper position. 502 DISE ASES OF JOINTS, CARTILA GES AND LIGA MENTs. Reduction is often very difficult, but to be attained usually by extension and counter-extension in the direction of dislocation plus direct moulding pressure. Retention after reduction is frequently impossible, but fortu. nately no great deformity or loss of function ever results if dislocation persists. An anterior angular splint and direct compress must be kept on for three weeks. Dislocations of the Upper End of the Ulna. Dislocations of the upper end of the ulna take place in a backward direction as a result of indirect violence. The injury is a very common complication of high radial fracture. FIG. 312. Dislocation of upper end of ulna. (CoopFR.) The radial head remains in position, but the ulnar extremity is displaced beneath the condyle of the humerus; the forearm is rigidly fixed at a right angle and pronated. Reduction is accomplished by placing the knee in front of the elbow and making right angle traction upon the forearm and direct pressure upon the displaced end of the ulna. This failing the forearm should be hyperextended and traction made upon it, thus con- verting the ulna into a lever of the second class, which brings the coronoid process over the condyles of the humerus. Dislocations of the Lower End of the Ulna. Dislocations of the lower end of the ulna, from its articulation with the radius, take place in either forward, backward, or inward direction; the forward variety being induced by violent supination of the forearm, and the backward form by forcible pronation. Reduction is easily accom- plished by fixing the radius and then restoring the ulna to proper position by direct pressure. Antero-posterior splints should be kept on from three to four weeks. Dislocations of the Carpus. This dislocation almost never exists without fracture. The direction of displacement is either forward or backward, and is to be diagnosed by the abrupt angle formed by the displaced carpus and the extremities of the SPECIA.

Pressure will usually reduce them, but failing in this they should be ex- °ised through a sufficient incision. A pad, palmar splint, and bandage must be applied and worn for about a week. Dislocations of the Metacarpal Bones. Dislocations of the metacarpal bones are not uncommon, in direction º either an upward or backward direction, and are easily reducible y the usual method of extension and pressure. Dislocations of the Phalanges of the Hand. Dislocations of the phalanges of the hand are of common occurrence, usually taking place at the metacarpo-phalangeal junction. They are, as 504 DISE ASES OF JOINTS, C A RTILA GES AND LIGAMENT's, a rule, difficult neither of recognition nor treatment; simple traction by the hand of the surgeon, perhaps assisted by a clove hitch about the in- FIG, 3.15.

Reduction must then be accomplished by manipulation as follows: extend the thumb upon the wrist until its tip points to the elbow, when the end of the phalanx will press upon and separate the then relaxed heads of the short flexors; then place a finger behind the phalanx to pre- vent its head slipping upward, and bring the thumb down to its proper position. This manoeuvre failing, the restricting tendon must be divided by subcutaneous or open incision. The parts, in any case, must be kept at rest by a spica of the thumb or splint for three weeks. Old dislocations of this joint may demand, should all of the above measures fail and dis- ability justify, the excision of the metacarpal head, or even amputation of the member through the metacarpo-phalangeal joint. Dislocations of the Femur. Luxations of the femur take place at the hip-joint, and comprise about nine per cent. of all dislocations. The head of the femur, after leaving the acetabulum, may occupy any position about the joint, depending upon the direction of the applied force, the position of the limb at time of accident, and the extent of liga- mentous and muscular lacera- FIG. 319. tion. As a rule, regular dislo- cations may be said to occur when one or both branches of the ileo-femoral ligament remain intact, and the irregular or anomalous when that ligament is extensively or completely lacerated. The rôle of this liga- ment in the production and treatment of hip dislocations is of extreme importance. It origi- nates upon the front and outside of the anterior inferior spinous process of the ilium, crosses downward, spreading over the anterior surface of the hip- joint, and divides into two por- tions; the outer to be inserted into the trochanter major, and the inner into the trochanter millor. This ligament being ex- tremely, powerful, usually pre- vents the head of the femur quitting the acetabulum save in a posterior or lateral direction. Femoral dislocations are al- Ways caused by indirect violence, and may be classed in two great divisions: those where the head Ileo-femoral ligament. (BIGELow.) is thrown anteriorly to the gle- noid Cavity, or forward dislocations, and those where it is displaced pos- teriorly, or backward dislocations. Of each of these classes there are 506 DISE A SES OF JOINTS, C A RTILA GES AND LIGA MENTs. two principal varieties, which will be described, also a great number of unpractical subdivisions which will not be separately considered. Back- ward dislocations comprise more than three-fourths of hip displacements. They are divided into those directly backward into the sciatic foramen (ischiatic), and those backward and upward upon the dorsum of the ilium (iliac). The upward variety is most common of all hip dislocations, whilst the directly backward dislocation ranks second. Of forward dislocations we have the forward and downward into the thyroid foramen, and the forward and upward upon the pubis, or pubic dislocation; the latter being rare, but the former ranking third of all hip displacements. The capsular and round ligaments are invariably torn, and the femoral vessels may be injured in forward, and the sciatic nerve in backward dislocations. Femoral dislocations are invariably to be first treated by manipulation under profound anaesthesia, but should this method fail, then extension and counter-extension in the line of dislocation may be judiciously em- ployed; but should both measures prove inefficient after several trials, at intervals, incision and division of the restricting tissues, section of the neck, or even excision of the head, should receive consideration. Posterior or Backward Dislocations. When these dislocations occur the capsule is ruptured posteriorly upon its outer aspect, and the head of the bone is shot in a backward or upward and backward direction. Backward and Upward (Iliac or Dorsal) dis- JFIG. 320. placements take place when the limb is abducted and forcibly rotated inward, or by a force applied from below when the legs are crossed. Simple inward rotation, however, may prove sufficient for its production. SYMPTOMs.-The thigh is somewhat flexed and adducted, the knee of the injured thigh is slightly above and in front of its fellow, and is in contact with the lower and inner portion of the oppo- site thigh. The foot is forcibly inverted and the ball of the great toe touches the inner portion of the opposite instep. The injured hip is exceed- ingly prominent, whilst the head of the femur can usually be felt upon the dorsum of the ilium. There is shortening of the injured limb to the ex- tent of from one to two and a half or three inches, according to the height of the head upon the ilium ; flexion and extension are moderately interfered with, but the motions of adduction and abduction are almost impossible. Numbness or tingling of the sciatic distribution may or may not be present, but in any case always is moderate. Backward and upward Backward (Ischiatic) dislocations occur whilst (or iliae) dislocation of the thigh is at right angles with the pelvis and is the femur. (CoopFR.) abducted and rotated inward; the head of the femur is displaced directly backward and comes to a stand- still in the sciatic foramen. Portions of the glutei, gemelli, and obturator externus muscles are usually lacerated by the head in transit. SPECIAL DIS LOCATION S. 507 SyMPTOMs.-The thigh is slightly flexed, inverted, and adducted; the knee touches the opposite limb at the inner and upper margin of the atella. p The extremity of the great toe of the injured side just touches the metatarso-phalangeal articulation of its fellow. Shortening never exceeds half an inch, and may even be lacking, Its presence is best demonstrated, as FIG. 322. suggested by O. H. Allis, if the thighs be flexed to a right angle with the pelvis and the condyles of the femurs compared. The hip is somewhat prominent. Numbness, tingling, or palsy of the sci- atic distribution may be very marked. The head of the femur is lower and less prominent than in the upward FIG. 321. **-- - - Allis's test for shortening in backward Backward (ischiatic) dislocation of dislocation of femur. the femur.

Rectal or vaginal examination may clear up a doubtful diagnosis by demonstrating the head in the Sciatic foramen. Treatment of Posterior Dislocations (Iliac and Ischiatic). Reduction can almost always be accomplished by manipulation. The Patient should be etherized to relaxation and placed flat upon his back. The surgeon then grasps the leg at the foot and knee, flexes the leg upon the thigh and the thigh upon the abdomen; then adducts the limb and *9tates it outward, carries it to the sound side, sweeps it outward across the abdomen, and brings it out straight, when the head will return to the socket, perhaps with a very audible snap. . It will be observed that during these manipulations the ileo-femoral ligament is relaxed by flexing the thighs, which also in the simple back- Ward dislocation frees the head from possible entanglement with the *ndon of the obturator internus; that external rotation and circum- 508 DISE A SES OF JOINTS, CARTILA GES AND LIGA MENTs. duction winds the outer branch of the ileo-femoral ligament around the neck of the fermur and thus carries the head over the acetabular rim and into normal position.

Anterior or Forward Dislocations. Forward and downward (thyroid or obturator) dislocations result from the application of force when the limb is abducted; the inner and posterior portions of the capsular ligament are torn and the head of the femur is . thrust into the thyroid foramen and rests upon the obturator externus muscle. SYMPTOMS.–The limb is lengthened from one to one and a half inches, abducted, and the heel is somewhat raised when the patient stands, The toes point forward and may be everted; the hip is flattened and the trunk is inclined forward and to the injured side. The femoral head can be distinctly felt below the horizontal ramus of the pubis. These symptoms are to be interpreted as follows: abduction is due to tension of the glutei muscles and to the tenseness of the inner branch of the ileo- femoral ligament; the body is inclined to relax the stretched psoas magnus and iliacus muscles. TREATMENT must be conducted whilst the patient is fully relaxed by anaesthesia. Reduction is accomplished by manipulation, exactly as for backward dislocations, save that inward rotation and circumduction are here employed. e Thus the psoas muscle and ileo-femoral ligament are relaxed by flexion, and the internal branch of that ligament is wound about the neck of the femur in inward rotation and circumduction, and draws the bone over the acetabular rim into position. e Anterior luxations may be converted into posterior varieties during manipulation, when obviously rotation and circumduction must be made as for reduction of the latter class.

(AGNEw.) ground, and the bony head can be felt in front of, or above the pubis. Abduction and eversion are due to tension of the anterior branch of the ileo-femoral ligament and external rotators of the hip. Reduction is attained by the same manipulation as for forward and downward displace- ment, but flexion and abduction, previous to internal rotation, should be more decided. Old Dislocations of the Femur. Femoral luxations are termed old when they have remained unreduced upward of six or eight weeks; reduction has been accomplished many times when the injury had persisted to periods as long as five years. Prudent attempts should be made in any case, regardless of duration, by appropriate manipulation and extension and counter-extension; never, however, employing great force or persistence. If there is a history of inflammation, or if great changes have occurred in the acetabulum or femoral head, manipulative efforts should not be attempted. In any case if deformity and disability are great section of the femoral neck or excision of the head may become permissible. Subtrochanteric section of the femur may, in other cases, be employed with good results, and should fracture occur at or near this point during reduction endeavors it will be fortunate as then passive motion can be kept up and a useful false joint thereby S P E CIA.

The Sciatic nerves may be torn during reduction ; Dislocations of the Tibia. Dislocations of the tibia occur at the knee-joint and include 1 per cent. of all dislocations. backward, outward, and inward. Rotary dislocation also, but rarely, is produced by twisting force. Any of the prin- cipal varieties may be complete or par- tial. These injuries, especially if com- plete, are always serious, and are. accompanied by such extensive lacera- tion of ligaments and surrounding tis- sues and vessels as to demand excision or amputation. The popliteal vessels and nerves are especially liable to stretching or rupture; a clot may sub- sequently be formed in the artery. The direction of displacement can be recog- nized with facility by the bony land- marks of the joint, but occasionally, when complications or great swelling have occurred, anaesthesia may be neces- sary to confirm or make the diagnosis. Shortening will be present if there is overlapping; the part may be either rigid or flaccid. The direction of the foot will indicate rotary dislocation and its direction, should the displace- ment have assumed that type; the crucial ligaments are almost invariably torn. Reduction of tibial dislocations is made by traction, extension; and oppo- site rotation for the rotary variety. Subsequent rest upon a posterior splint for several weeks is essential. Then massage and passive motion. Anky- losis of varying degree is apt to suc- ceed.

This failing, especially in complete rotations, incision and forcible replacement be. come necessary. Dislocations of the Fibula. Dislocations of the fibula take place at either of its extremities. The bone is forced from its tibial articulations, and forward, upward, or back- ward displacements are possible. To reduce them the knee is partially flexed and direct pressure is applied, and succeeded by splint or bandage. Dislocations at the Ankle-joint. . Under this head are included only dislocations of the foot as a whole from the tibia and fibula. These occur backward, forward, and laterally, are most frequently associated with fracture, and as often difficult to dif- ferentiate therefrom. Lateral dislocation is almost always associated with fracture of a malleolus. They are to be reduced by flexion of the leg, direct pressure, and manipulation of the foot. Should contraction of the calf muscles constantly reproduce the dislocation and not be controllable by a temporary tight bandage, the tendo-Achillis must be divided. Dislocations of the Various Bones of the Tarsus. Dislocations of the various bones of the tarsus are not infrequent inju- ries, easily diagnosed, and are treated by direct pressure, manipulation, or should these methods fail, by excision of the displaced bone. The astragalus may be dislocated backward, forward, and outward, or forward and inward, In the former variety the extremity is shortened, the astragulus may be felt in front of one of the malleoli, whilst the foot is extended and twisted to the opposite side. When displacement is back- ward the foot is extremely flexed, the instep is short, and the heel elon- gated. The astragalus is to be felt beneath the distorted and tense tendo-Achillis. Reduction of the forward and lateral varieties can usually be performed by flexion of the leg, traction upon the foot, and direct pressure upon the astragalus. Division of the tendo-Achillis may assist in replacement. Backward dislocations usually prove irreducible, and the bone should be excised at once or at a later time. Metatarsal dislocations and those of the phalanges of the toes are rare injuries, usually due to crushing force necessitating amputation; other- wise they are to be treated upon general principles of reduction. DISLOCATION OF CARTILAGES. Dislocation of the Costal Cartilages. Dislocations of the costal cartilages from their various junctions with the sternum, the ribs, and from their points of mutual contact, are poss!" ble, but of very infrequent occurrence. Direct or indirect force is always the causative factor. * • * * • , o, . * * s' ** * * A * * ' (y, SPECIA. L ID ISL O C A TI O N S. 513 Symptoms are undue prominence or depression at the seat of articula- tion, undue mobility, perhaps modified crepitus, pain, or disturbed respi- ration. These displacements are to be treated by moulding, manipulation of shoulders, forced expiration or inspiration, and after reduction are to be kept in place by means of suitable pads or bandages. Dislocation of the Ensiform Cartilage. Dislocation of the ensiform cartilage has only twice been reported ; in both instances backward and by direct force. Symptoms were intense gastric pain, and vomiting, embarrassed respiration, absence of ensiform upon palpation. Reduce by same methods as for dislocated costal carti; lages. If distress is great, and these methods fail, a hook may be inserted through the integument and beneath the tip of the ensiform, when it may be drawn back into position. Or a finger may, through an incision, be likewise hooked under the cartilage. If it cannot be so reduced, or if dis- location is constantly repeated, then nothing will remain but to excise the offending cartilage through a vertical incision of its own length directly over it. The cartilage is then seized with lion forceps, its surrounding attachments carefully divided, it is withdrawn, and the wound sutured with or without a small drain. As life advances dislocations of chest cartilages give place to fractures, because of the ossific deposits in these cartilages in the aged. Treatment would be the same as that for fracture of the respective proximal bones. Dislocation of the Semi-lunar Cartilages. Dislocation of the semi-lunar cartilages is not an uncommon injury; is directly produced by excessive flexion or a sudden wrench, and is almost limited to persons of middle age, especially those who have lax or previously diseased joints. The displacement is generally backward, but may be in the opposite direction. Both cartilages may participate in the dislocation, but more usually the inner one alone is affected. Both knees may be attacked at the same or different times. The etiological factors are a relaxed or previously lacerated knee-joint or crucial liga- ments, and excessive flexion; by which the cartilages are forced out of place, perhaps crumpled upon themselves, and become wedged at some point between the femoral condyles and the tibia, stretching or tearing the crucial ligament, if they have not previously been the seat of rupture, and appreciably separating the articular surfaces of the bones entering the joint. SYMPTOMs. During stooping, squatting, kneeling, or other excessive flexion of the knee a sudden, intense, sickening pain is experienced in one or both knee-joints. The joint has become locked in a position of extreme flexion and cannot be extended by the patient or by application of force. If predisposition exists the accident may happen to a joint When it is but partly flexed, and when dislocation occurs perhaps throw the person violently down. Compared with the corresponding joint the ones entering it are notably separated, and perhaps the displaced carti- lage can be felt in the interval. If the luxation is not soon reduced effusion will take place, inflammation arise, and, possibly, abscess later . Even when early replaced, effusion and a sharp synovitis may OW. 33 514 DIS E A SES OF JOINTS, C A RTILA GES A N D LIG AM E N T S. TREATMENT.—The displacement can almost always be reduced instantly by hyperflexion of the knee over the edge of a table or around a bed. post, followed, while extension is made by a hand behind the calf, by sud. den full extension. For this anaesthesia is advisable, as the accompanying pain is great. Following reduction of such FIG. 332. cases the joint should be immobilized for three weeks by a plaster dressing or splint that inflammation may be averted and the ruptured ligaments be given a chance to unite. If reduction cannot be thus accom- plished after a number of efforts, and in cases where constant recurrence (which cannot be prevented by wearing a tense rubber knee-cap or apparatus which will prevent more than a slight degree of flex- ion) renders a patient unfit for occupa- tion or enjoyment of life, the following operation, devised by Annandale, should be forthwith performed.

The synovial and superficial wounds are then separately sutured and, the limb being extended, a plaster dressing or suitable splin' is applied and not removed for several weeks, when gentle passive mo"? ments may be made, and at the end of two months the patient may be E X CIS I O N OF J O IN T S. 515 allowed to walk. This operation failing to give relief, the affected cartilage may, through a similar incision, be bodily excised. OPERATIONS UPON JOINTs. Aspiration of joints is performed by introducing an aspirator needle through the perfectly cleansed integuments, usually at the most promi- nently distended point, into the joint cavity, and thereby withdrawing the fluid contents. Washing out or irrigation of joints may be performed either by pump- ing the irrigating solution through the aspirator needle, and then sucking it out again, by introducing two canulae upon the same or opposite sides of the articulation and pumping in through one and out through the other, or by making a short incision in the axis of the joint and through it pumping the fluid.

All por- tions of the synovial membrane, other affected tissues, and sinuses, must then be totally eradicated by scissors, curette, knife, or cautery. Sinuses should be bodily excised, when possible. If deep and inaccessible, a curette should be carried into them as far as possible. FIG. 344. Barker-Willard irrigation curette. The tourniquet is now removed, and all hemorrhage stopped. Bleed- ing from bone medulla can be controlled by a few moments' pressure with a finger or pad, or by packing in a small wad of fine catgut and leaving it. Carefully wash out the cavity, insert a good-sized rubber drain in large joints or a hank of catgut into small ones, restore all parts to as near normal position as possible, suture, dress copiously, place the limb upon a proper splint, and always keep it elevated for the first half day or so. - g Most joints can be so excised and dressed that but a single dressing completes the cure. The dressing in no case should be changed under three or four weeks or more, unless there are distinct indications therefor: E X C ISION OF J O IN T S. 519 Where fibrous union or false joint is required, dressings may be changed and motion be commenced in four weeks. When unabsorbable drains are left in, the wounds should always be dressed and the tubes removed not later than the first week. Some form of mechanical support will be required for a long time after many excisions. y PROGNOSIS.—With modern methods excisions, when early undertaken, have come to be quite Safe and successful, and the scope of the operation has become correspondingly extended. Risk of operation increases as the trunk is approached. Evcision of Temporo-maxillary Joint. Excision of the temporo-maxillary joint is performed by making a one and a half inch vertical incision downward from a point just behind the middle of the zygoma, but in front of the temporal artery, carrying it down through the masseter muscle, exposing the neck of the jaw, dividing it with Adams's saw or cutting pliers, and then freeing the separated condyle from ligamentous attachments. Simple Osteotomy of the neck of the bone is preferable for ankylosis at this joint. Temporary palsy of some of the facial muscles may follow division of the seventh merve fibres. Evcision of Shoulder-joint. Make a four-inch vertical incision, beginning at the anterior tip of the acromion process, and carry it downward through an inter-fascicular partition of the deltoid until the capsule is opened and the humeral shaft exposed. Free the deltoid FIG. 345. from its capsular attachments. Divide the capsular attachments of the head, and also the tendons in- Serted into the tuberosities, rotating the arm inward to divide the then tense spinati and teres minor attachments, and outward for the subscapularis. Dissect the long head of the biceps from its groove, and hold it aside. Throw the humeral head outside of the wound by carrying the elbow across the chest toward the opposite side and then pressing it upward and outward. Saw off the head with a Butcher's or other saw, and trim any sharp edges or spiculae left. If a common amputating saw is used, the soft parts must be protected by a disinfected Strip of wood or hard rubber. Remove all diseased tissues, gouge out the glenoid cavity, or, if it is ex- tensively involved, cut it away with pliers. Wash Out the cavity, control bleeding, drain, suture, and dress in such position that the cut extremity of the humerus is in the glenoid cavity. That is, get Excision of shoulder- he bone into position, dress and bandage as for joint Lineofincision. facture or dislocation in the same locality. Re- dress in about three or four weeks, and then, if the wound is suffi- °iently healed, commence passive motion, massage, and electricity. A th 520 DISE A SES OF JOINTS, C A RTIL AGES AND LIG AMENTS, very useful arm may be looked for ; the muscles shorten, and a false joint forms. Abduction will be much impaired, but the forearm will be as good as ever. Evcision of Elbow-joint. The arm is avascularized by the rubber band or elevation and tourniquet, slightly flexed and brought over a pillow or block with the olecranon look- ing upward. Incision is begun two inches above the centre of the olecranon and carried vertically downward four inches, bareing the humerus above, the ulna below, and opening the joint in the FIG. 346. centre. The articular extremities are then separ- ated from their muscular and ligamentous attach- ments, great care being observed to dissect the ulnar nerve from its groove on the inner side of the joint and to keep it held out of harm's way during the subsequent manipulations. The nerve is gotten out by slipping a director into the canal from above and dividing the outer wall upon it. Now the olecranon process is cut from the ulna with pliers, the lateral ligaments, if still present, are divided with a strong hermia knife, and by flexing the joint the remaining bones are thrown outside the wound and sawn off. If permissible, not more than the articular surface of the humerus, the olecranon above the coracoid process and the radius above its tubercle should be taken away. | The soft parts must be protected whilst the saw- . . . . * tº ing is done.

Catgut drains will often answer here. Re-dress in three or four weeks and commence motion. At the elbow false or movable joint is always desired. A mechanical appliance must usually be worn. If no more bone than has been indicated is removed the result will be good and the forearm preserve excellent functions. But if more, espe- cially of the radius and ulna is taken away, power of flexion is obliter- ated by removal of the insertions of the biceps and brachialis anticus, and rotation much interfered with ; in fact, above the forearm the member will be useless, although below that point all will continue as before. i l t t t y g ; ; f ! ft | / . ! | f | } : j | Evcision of Wrist-joint. By excision of the wrist-joint is meant removal of the ends of the radius and ulna and of the first row of the carpal bones; and, perhaps also of one or more of the second row, or even of the metacarpal extremities. Great patience, caution, and anatomical knowledge are here requisite. The parts are rendered avascular and an incision is made beginning at or upon the outer surface of the forearm two inches above the styloid process of the radius at a point just inside the inner margº of the extensor communis digitorum and carried in a downward and inward direction along the margin of that muscle and the tendon of the extenso" E XC ISION OF J O IN T S. 521 indicis, until about the centre of the metacarpal bone of the index finger is reached. The flaps are now well dissected back, and all underlying tendons running over the joint freed from their sheaths and held aside by retractors. If the pisiform bone is to be removed the attachment of the flexor carpi ulnaris to it must be divided. Occasionally, the extensor carpi radialis longior, or brevior cannot be gotten out of the way; so must be divided and the ends marked by threads or otherwise for subse- quent recognition and suture. FIG. 347. º Excision of wrist-joint. Line of incision. No tendons should be cut unless positively necessary, but when so, any number may be freely divided, marked, and after removal of the bones sutured. All tendons being out of the road, the radio-carpal ligaments are divided, and, by strongly flexing the hand, the radius and ulna are thrown out of the wound. Their under surface is then freed carefully from tendons and nerves and the necessary amount sawn off. The hand is then brought back, the inter-carpal joint opened and the first row of bones excised, either individually or en masse, great caution being observed when working near the radial artery. The second row should likewise be removed if diseased. If required, the metacarpal ends can be cut off best with pliers. The synovial mem- brane and other diseased structures are then carefully removed, the cavity Washed out, hemorrhage controlled, any divided tendons sutured, and a drain, dressing and palmar splint applied. Passive motion of the fingers should be commenced early. Excision of the wrist is not a favorable operation, and the results are often Wretched. Still, if even slight use of the fingers is retained, the Patient will value the member much more than an artificial limb. Ex- CŞion may be performed in apparently hopeless cases, and, should it com- Bletely fail, amputation can be done after the member has been given a final chance. * Excision of any particular bone or bones of the carpus may be made by the above (but more curtailed) incision, or by one directly over the affected area. 522 DISE A SES OF JOINTS, CARTILA GES AND LIG AMENTs. Eveision of metacarpal provimal evtremities can be made by a one and a half inch vertical, incision directly over the joint, through which pliers cut off the extremity. Evcision of Metacarpo-phalangeal, and Inter-phalangeal Joints. Excision of metacarpo-phalangeal and inter-phalangeal joints can be performed through a vertical one to two-inch incision upon the upper aspect of articulation. Articulating extremities are separated from their bone shafts by cutting pliers and removed. No drain is required as a rule. Evcision of Hip-joint. Usual Method.—The patient is turned upon his sound hip, and the oper- ator stands facing the patient's back. Incision is begun one and a half inches above and a little posterior to the great trochanter, and carried down vertically in the femoral axis for a distance of five or six inches. The bone is then exposed for the entire distance. Now the capsule is FIG. 348. s = **** _- ºr * * x *** **, * * *s 2 * * s A * * t t t | \ | l | l | | t ſ Excision of hip-joint. Line of incision. freely opened, and the neck of the femur divided transversely by an osteotomy or metacarpal saw, or, if in a young child, by cutting pliers. The head of the bone is then seized by lion-jaw forceps, the round ligament divided if it still remains, and the separated bone removed. All possible diseased structures are then eradicated, the cotyloid cavity well gouged out and irrigated, all bleeding stopped, a large drain carried to the bottom of the wound, and a copious dressing applied. Outside this, some steadying apparatus, such as a plaster dressing to the whole limb and chest, exten- sion and sand-bags of a side splint must be applied to secure perfect sub- sequent rest of the involved parts. Lateral pressure upon the wound by E XC ISI O N OF JOIN T S. 523 a hip-band or sand-bag is advantageous for a few days after the operation, as also is moderate elevation of the limb to promote muscular relaxation and drainage. As much more of the femur as may be diseased must always be cut off, after separating the muscular attachments of the trochanters and inter- trochanteric line. By sparing the trochanter minor the psoas and iliacus attachments will be saved. The acetabulum, if diseased, may be cautiously clipped away. A high-heel shoe will be required upon the affected foot, and usually some sort of a leg-brace, having attachment to a body corset; if much of the femur has been taken FIG. 349. away, crutches, in addition, will be required. Second Method.—This is applica- ble to cases requiring excision in the earlier stages before great bone de- struction has taken place or abscesses FIG. 350. | i| t | \ Excision of hip-joint by anterior method.

Incision begins upon the front of the thigh half an inch below the anterior superior iliac spine and continues downward and a little inward for a distance of three inches. In following his line, the knife gains free access to the capsule and joint by sinking between the tensor vaginae femoris and glutei muscles on the outside, and * rectus and sartorius on the inner side. The joint is them opened and 524 DISE AS ES OF JOINTS, C A RTIL AGES AND LIGA MENTS. irrigated, the saw introduced, and the femoral neck divided in the direc- tion of incision, and removed after division of the round ligament. The other steps of operation are identical with the method already described. Evcision of Knee-joint. This joint should always be brought into as extended position as possible by gradual pulley extension before excision is undertaken ; otherwise much bone must be needlessly sacrificed, or too much tension excited in bringing it straight at the time of the operation. FIG, 35l. The extremity having been made as straight as possible and avascular, an incision is made from a point in the centre of the thigh three inches above the centre of the patella directly downward to the tubercle of the tibia. (Fig. 350.) The flaps are then held back and the patella is sawn through vertically. Next the quadriceps and patellar tendons are slit to their full extent, the knee still further bent, and one-half of the patella and its attachments pulled to each side as the other bones of the joint are shot out, and the crucial ligaments divided. The neces. sary amount of the femoral condyles and tibial head (usually about half an inch of each) are then sawn off by either a Butcher saw from s without inward, or by an amputating saw in W the opposite direction. In the latter case the contents of the popliteal space must be pro- tected by a strip of hard rubber slipped beneath the bones. Then the synovial membrane or diseased cancellous structures are eradicated as usual, all the remaining cartilage cut away, the tourniquet removed, hemorrhage controlled, the bones returned, and the cavity well irrigated. After reduction of the bones, the patella should be dissected out if found diseased. Care must be exercised not to wound the popliteal vessels whilst sawing or cutting away affected soft parts. The bones may be nailed together by steel nails through the skin after the parts are sutured, but it is preferable to drill holes through them and into these insert powerful sutures of chromi- cized catgut, or through them drive ivory or - bone nails, so as to fasten the bones rigidly Bone drill together. The patella likewise, if not diseased, is sutured, or drilled and nailed, and the split quadriceps and patellar ligaments are united by catgut stitches. Drain- age is to be assured by passing tubes through openings made through the skin on either side of the bottom of the wound, and one from above, around the patella into the subpatellar region. Copious dressings and a long posterior splint are then applied, and the limb kept elevated, for several days. If the case is successful—that is, bony union and ankylosis are secured—the patient may be allowed to walk in from eight to tell weeks. Shortening is obviated by raising the appropriate heel. No brace will be required unless bony ankylosis does not occur. | } º º Dº : } d§ % º § ºº§º E X CISION OF JOIN T S. 525 Modifications.—If conditions will permit, incision may be made along the inside of the tendons and patella and that bone and its attachments slipped entire to the outer side of the joint when the bones are shot out. Or, if disease is very exten- FIG. 352. sive, incision can be made transverse and the Ø | patella sawn through in the same direction. In ſ % excision for deformity incision may be in either direction, the flaps separated, and a sufficient wedge to correct deformity taken from the anky: | losed bones as a whole. If the case is complicated by contraction of the hamstring tendons, or if there is any tension upon these after operation, they should be divided subcutaneously with a tenotome. Excision of the knee is almost absolutely safe in properly selected cases and is in them quite certain to yield a good result and a perfectly serviceable limb. ; ; : 3 tº; m Evcision of Ankle-joint. After avascularization an incision is begun three inches above the external malleolus and carried downward along the posterior margin of the fibula, around the malleolus and forward to within half §.5 an inch of the base of the fifth metatarsal bone. Bone drill. The flap is dissected up and the peronei tendons divided. The lower end of the fibula is now cut with saw or pliers and the external malleolus removed, when the astragalus comes into view. The foot is then inverted and the upper surface of the astragalus sawn off, or the whole excised if extensively diseased. Next the end of the tibia is cleared of all attachments and the necessary amount sawn off and removed. If this cannot be readily accomplished through the primary incision upon the inner surface of the foot, another incision running around the internal malleolus and terminating at the cuneiform bone should be made. This flap is dissected back, the tendons, nerves, and vessels are carefully displaced from their grooves and either the tibia shot out or a narrow-bladed saw inserted behind the bone and made to cut from behind forward, the soft parts being meanwhile held aside and protected. The divided portion of tibia is then freed from attachments and extracted through either wound. The leg and foot must afterward be kept upon a right angle splint or in a fracture-box. If it has been necessary to divide any tendons they must subsequently be sutured. The results of ankle excision are not gratifying so far as subsequent usefulness is concerned, although the wounds heal well and the parts Present a good appearance. Amputation is usually the preferable measure at this joint. Pºcision of Metatarso-tarsal, Metatarso-phalangeal, and Inter-phalangeal Joints. Excision of metatarso-tarsal, metatarso-phalangeal, and inter-phalangeal Jºnts is performed in the same manner as are corresponding excisions of the carpal articulations. But as the digits are comparatively useless, *d as deformity following the operation may impede locomotion or pro- duce discomfort, amputation is usually to be preferred to excision. C H A P T E R X. I X. RESPIRATORY ORGANS. SURGICAL DISEASES AND INJURIES OF THE NOSE. Foreign Bodies in the Nose. SMALL stones, beads, and peas are occasionally pushed into the anterior nostrils by children and become fastened in the nasal chambers. Very rarely small seeds or fruit stones may get into the posterior nostrils during vomiting. Such foreign bodies, if allowed to remain, set up inflamma- tion of the mucous membrane of the nose and give rise to an offensive discharge which sometimes is mistaken for grave disease of the nasal structures. Foreign bodies should be removed from the nasal cavities by a small hook, such as comes in pocket cases, or a strabismus hook or some similar instrument. It is usually necessary for the surgeon to illuminate the nasal cavities by means of a forehead mirror. When foreign bodies cannot be removed in this manner they may be washed out of the nostrils by means of a douche. The tube of the douche is placed in the nostril opposite to the one which is occluded, while the patient's head is bent forward with the mouth open. The stream of water then passes around the posterior border of the septum and into the closed nostril behind the foreign substance. This latter is then washed out by the current coming from behind. The foreign body might be pushed back into the pharynx and thus removed, but there is danger of it falling into the glottis and of producing asphyxia. It is better, therefore, to extract such sub- stances from the anterior nares. Rhinoliths, or nose stones, are concretions of phosphate of lime and mucus which sometimes form in the nose, having for their nuclei small crusts of secretion or foreign bodies. These rhinoliths should be removed in the same manner as foreign bodies. If they are large they can be crushed previously with a pair of forceps. Epistaais. Bleeding from the nose may be the result of injury, or it may occur as a symptom of fibroid or malignant tumors in the nose or pharynx. . It occasionally occurs spontaneously, and is due in such cases to congestion, of the mucous membrane; often associated at the time with congestion of the brain, cirrhosis of the liver, granular kidneys, heart disease, ScurVY: or some of the essential fevers. It is due occasionally to impoverished condition of the blood, and is, as is well known, an early symptom of typhoid fever. Bleeding is said to occur at times from small ulcers upon the mucous membrane. tº Epistaxis is usually exhibited by an escape of blood from the anterlºº nostrils, but it may run backward into the pharynx and, getting into the E PISTA X J S. 527 stomach, be subsequently vomited, giving the appearance of haematemesis. It may get into the larynx and be coughed up in a red, frothy state re- sembling haemoptysis. Such errors are avoided by examination of the pharynx and fauces in a good light. When the blood comes from the nose it will be seen trickling down the posterior wall of the pharynx. The treatment of epistaxis involves the consideration of the causes which lead to its occurrence and repetition. The visceral factor in such bleeding should be treated by appropriate medical means. Traumatic epistaxis, as a rule, ceases spontaneously and needs no treat- ment. It should be remembered also that in cases of plethora, in which there is congestive headache or other symptoms of cerebral engorgement, bleeding from the nose may be a salutary symptom. Internal remedies, such as gallic acid, preparations of lead, opium and ergot, are given to diminish the tendency to nose-bleeding, but are of little value at the time of its occurrence. In cases of moderate severity the patient should be made to lie down with his head considerably elevated, and with iced #, FIG. 353. & i. § * g * ; § § ; # § * sº : W : : g * Method of plugging the nares from in front. cloths applied constantly on the nose. He should then grasp the carti- laginous portion of the nose with his thumb and forefinger in such a way * to keep the nostrils tightly closed. This will prevent respiration through the nose and thereby permit clots to form, thus arresting the flow of blood. The firm pressure by the fingers prevents the access of air *nd gives an opportunity for the clots to close the bleeding orifice. It has been Suggested that pressure with the finger upon the facial arteries will limit the amount of blood flowing through the nose and aid in arresting hemorrhage. When these simple measures are not sufficient to arrest the bleeding, and the patient shows signs of great exhaustion from the loss of blood, ** Proper to plug the nose upon the side which is bleeding. This may 528 R E SPIR A TO R Y O R G A N S. by done by passing a long and narrow rubber bag, from which the air has been expelled, along the floor of the nares so that it will extend from the anterior nostril to the posterior nostril, and inflating it with air. Pressure is thus made upon the walls FIG. 354. of the nasal cavities. The most effectual means of plugging the nostrils is by means of small pieces of Sponge threaded upon a strong cord. The proper method of doing this is to tie a piece ºº:: of antiseptic sponge, about as large as a India-rubber inflating tampon for good-sized marble, to the end of a piece of silk plugging the mares. ligature. The sponge is then pushed along & the floor of the naris until it reaches the posterior opening of the nasal cavity. That it has been pushed all the way back can be determined by the length of the string, or by the surgeon putting his finger into the pharynx. When this first piece of sponge has been properly placed, a single string will hang out of the anterior nostril. A similar piece of sponge with a hole in the middle should now be threaded upon this string and crowded back by means of the forceps into the nasal chamber. By thus packing with successive pieces of sponge the whole nasal chamber from the anterior to the posterior opening, bleeding is absolutely prevented by pressure of the sponge completely filling the masal cavity. The sponge may be allowed to remain in place for from twenty-four to forty-eight hours. If the nose has been thoroughly washed out previously with an antiseptic solution, which of course must be of the non-poisonous kind, and if the sponges and silk are thoroughly antiseptic, there is little danger of putrefaction even when the packing is allowed to remain for a longer time. Usually, however, from thirty-six to forty-eight hours is sufficient to preclude the possibility of recurrence of the hemor- rhage. This method is far superior to the use of Bellocq's canula, or any modification of the principle by which a string is brought out of the mouth after being attached to a plug thrust up behind the soft palate. Nasal Catarrh, The term masal catarrh is used to indicate inflammation of the mucous membrane of the nasal cavities. It usually shows little or no ulceration. There are three forms. 1. Simple nasal catarrh, in which there is a thin mucous or muc0: purulent discharge without thickening of the mucous membrane and without incrustation of secretion or fetid odor. * 2. The hypertrophic form, in which the mucous membrane, especially that over the turbinated bones, is swollen and infiltrated with inflamma; tory deposits, and in which there is a change of voice and formation of crusts within the nose. tº 3. The atrophic form, often called dry catarrh, in which there is atrophy of the glands of the mucous membrane, so that the nasal cavities are enlarged beyond the normal condition, and are, of course, larger than is the case during the existence of hypertrophic catarrh, in which, the mucous membrane is swollen. The atrophic form is accompanied by great fetor, and seems to be a stage following the hypertrophic conditiºn: Offensive odor does not seem to be a characteristic of hypertrophiº 3 U R GICAL DIS E A SES AND IN J U R IES OF T H E N O SE. 529 catarrh, unless atrophy has begun in some portion of the diseased mucous membrane. The term ozaena is often indefinitely used by surgeons to indicate the existence of a fetid nasal discharge. The term should be discarded, how- ever, because such fetid discharge may occur in atrophic catarrh and in tubercular or syphilitic disease of the nose, as well as from foreign bodies impacted in the nostrils, and from other causes. Since the term ozºena conveys no idea of the pathological condition, it should not be employed. A head mirror and speculum, or rhinoscope, are necessary for the correct determination of these various conditions. TREATMENT.-The treatment of nasal inflammations, except when due to syphilis or gonorrhoea, is not very satisfactory, except in the hands of a specialist. Various forms of sprays thrown into the nose by means of an atomizer are valuable; and local treatment of various kinds applied directly to the diseased area are the most efficient means. Constitutional treatment is required to aid these local measures, since nasal disease may depend upon syphilis, tuberculosis, and other conditions leading to bad health ; but too much stress cannot be laid upon the necessity for efficient local treatment. Hypertrophied tissue may be removed by the snare, or by the application of the galvano-cautery, or the curette. Nasal Polyps. Tumors occurring within the nasal cavities, as sessile or pedunculated masses, are called polypi or polyps. The most common form of polypus is the myxoma, although fibroma, sarcoma, and carcinoma are not very infrequent. The myxoma is the one meant when the term polypus is ordinarily used. These polypi are soft, gelatinous, semi-translucent, pinkish or yellowish-white masses, which have their attachment to the mucous mem- brane in the neighborhood of the upper or middle turbinated bones; although they may arise in the antrum and other cavities connected with the nose. They seldom grow from the roof or septum of the nasal chambers, are generally covered with ciliated epithelium, and are mul- tiple, although one or two of the group generally exceed the others in size. In shape, they may vary from the globular to the pyriform or ovoid form. SYMPTOMS.-The respiratory obstruction due to the condition causes a Shange in the tone of the voice, giving it the so-called nasal sound. The interference with respiration is increased in damp weather, because the tumor swells from absorption of moisture. An increased feeling of stuffi- ness in the nose therefore occurs under such circumstances. There is $onsiderable nasal discharge, which is usually not offensive; some frontal headache at times, and, possibly, impairment of the sense of smell. The Patient is apt to be continually snuffling, because of the interference with *Spiration and the flow of mucus. , Obstruction of the tear-duct may 999 ºr secondarily, and the bones of the nose may be pushed out of place, * that the bridge of the nose is widened by the pressure of the internal *ors. Reflex cough and asthma have been attributed to nasal polypi. DIAGNOSIS.–Inspection of the interior of the nose will usually make the diagnosis clear, since hypertrophy of the mucous membrane and the * forms of nasal polypi show redness of the surface, very different from the yellowish pearly color of a mucous polypus. 34 530 R. E SPI R A TO R Y O R G. A. N. S. If the tumors occupy a high situation, or if they are not very largely distended by the absorption of moisture, it may be difficult to see them unless a speculum is used in the anterior nares, or a rhinoscope employed for the examination of the posterior nares. . The surgeon, by introducing his finger into the mouth and carrying its tip behind the soft palate, may sometimes be able to feel a mass protruding from the posterior mares into the pharynx. TREATMENT.-Extirpation of the tumors is the proper treatment, and may be done by the galvano-écraseur, or by avulsion with forceps. The cautery gives less pain and loss of blood, but, in any event, bleeding is not important and the pain need not be severe; the latter can be obviated by painting or spraying the interior of the nose with a solution of cocaine. When the surgeon desires to pull out a myxomatous polypus with the polypus forceps, this instrument should be introduced into the nose in such a manner that the blades open vertically; they should then be pushed up until the gelatinous masses can be seized near their pedicles and pulled from their attachments by twisting. The base may be cauter- ized with the galvano-cautery or some chemical agent. If the polypus protrudes from the posterior nares, a forceps introduced by the mouth may sometimes be effective. Intra-nasal fibroid polyps usually arise from the posterior part of the septum or from the superior turbinated bone, and may project into the pharynx, antrum, or pterygo-maxillary fissure. It may occur that the growth will force its way into the orbit, into the cranium, or out upon the cheek, having previously caused absorption of the bony walls of the nasal cavity. Such fibroid tumors may develop in the pharynx and grow into the nasal cavity, or they may extend from the nose into the pharynx, thus obtaining in both cases the name of naso-pharyngeal polypi. When such a growth has obtained considerable bulk it is impossible to determine whether it has had its origin within the nose or in some of the adjacent cavities. Obstruction due to fibroid polypus is more marked than that due to the myxomatous variety; and the tumor is distinguished by its hardness, redness, and tendency to bleed, and by the fact that its bulk is not changed by damp weather. This form of polypus occurs most commonly in young adults. It is treated by avulsion, ligation, or excision. The galvano-ecraseur may be found very useful in removing moderate sized fibroid polyps. When these growths have obtained considerable size it becomes neces: sary, if removal is desirable, to separate the nose from the face and turn down the organ, or to gain access to the tumor by splitting the upper lip and turning the ala out of the way. The upper jaw may in other instances be cut loose and turned outward so as to give access to the naso-pharyn- geal cavity, or the soft and hard palate may be split with the aid of a saw or chisel. These operations may be undertaken because of the obstrug- tion which the growth causes, or because of bleeding from it which threatens the patient's life. It is justifiable to adopt such radical meas: ures because of the non-malignant character of the tumor; whereas if it was known to be a malignant tumor such operations would perhaps be improper since complete removal would be scarcely possible. i- it is stated that such growths sometimes atrophy in patients reaching middle life, and that an operation which simply cuts away a portion of the tumor is preferable to the major operations. Ligation of the twº SU RG ICAL DIS E A SES AND IN J U R IES OF THE N O SE. 531 external carotid arteries has been practised in order to cut off the blood supply to the fibroma within the nose and thus assist in its shrinkage. Malignant polypi, which are sarcomatous or carcinomatous, increase rapidly, soon infiltrate the surrounding tissue, which undergoes ulceration, and produce involvement of the lymphatic glands. If operation is not undertaken very early it is usually futile. Recurrence is frequent, even after prompt interference. Adenoid Vegetations in the Pharyna. In the vault of the pharynx there occur during childhood growths of adenoid tissue somewhat similar to the hypertrophy of the tonsils, which is not uncommon at a similar age. This pedunculated, sessile, or fringe- like growth obstructs the breathing, impairs the quality of the voice, and interferes with the hearing. It is also apt to be associated with nasal and pharyngeal catarrh, or enlargement of the tonsils. The hypertrophic masses may be felt with the finger passed into the pharynx and are apt to bleed when manipulated. The obstruction to respiration causes the child to breathe through the mouth, and leads to symptoms pertaining to mouth respiration. These adenoid vegetations may atrophy as the child increases in age, but it is often necessary to remove them with forceps or curette because they induce deafness. The rhinoscope or head mirror is necessary in these operations. Astringent applications may be of some service in mild cases. Deformities of the Nose. Deformity of the nose may be congenital or the result of injury. Oc- casionally, as a result of injury, a blood tumor forms between the mucous membrane of the septum and the cartilage or bone forming that partition. These submucous collections of fluid resemble abscess of the septum and appear as soft swellings of the mucous membrane. Abscess is similar in appearance, but, as a rule, it follows signs of inflammation. Abscess of the septum should be treated by incision. These bloody extravasations, however, are usually slowly absorbed. Occasionally bony or cartilaginous tumors grow upon the septum ; they are usually near the floor of the nostrils. Such growths may even extend across the nasal chamber and come in contact with the lower tur- binated bone, forming a sort of bridge within the nose. It is not unusual for the septal cartilage to be more or less deformed, either congenitally or as a result of traumatism. Such deviation of the septum as well as the cartilage and bone tumors above spoken of, may lead to injurious FIG. 355. obstruction which will require operation. Piagram of deformities of nasal septum from author's “Cure of Crooked Noses.” Deformity due to syphilitic necrosis of the intra-nasal structures is *Pt to show itself in depression of the bridge of the nose which causes the tip of the nose to appear as a small elevation or knob upon the ante- 532 R E SPI R A TO R Y O R. G. A. N. S. rior portion of the face. The entire nose, or a very large portion of it, may similarly be lost from syphilitic ulceration. Portions of the nose may be also removed by wounds, and, therefore, require reconstruction. Improperly or carelessly treated fractures of the nasal bones and carti- lage often give rise to very unsightly deformities of the nose, causing it to have a bent or twisted appearance or to be the site of Some unbecom- ing projection. The surgeon is often required to treat such mal-forma- tions, and may, by judicious measures, restore the deformed outline. It is very difficult, however, to improve the appearance of a nose in which the bridge is sunken as a result of bone disease, or of congenital defi- ciency in development. A number of more or less complicated opera- tions have been devised for this purpose and are to a certain degree successful. A cartilaginous or bony tumor growing from the septum should be chiselled or sawed away, as the obstruction leads to breathing through the mouth, a disagreeable tone of voice, and often to nasal catarrh. If the septum is deviated to any marked extent it should be put into place by fracturing it with a strong forceps, or by incisions made into it with a small knife, and subsequently be retained there by pins. If the devia- tion involves a large portion of the septal cartilage, the cartilage should be made flaccid by a number of incisions cut in it with a stellate nose- punch before it is pinned into its new position. The point of a pin, which should be from one and a quarter to one and a half inches long, is then introduced into the more open nostril, after the septum has been broken or cut and made flaccid, and its point thrust through the anterior part of that portion of the septal cartilage which the surgeon wishes to control and keep in its new relation to the other portions. This part is pressed into the desired position and the point of the pin is then thrust forward through the other chamber of the nose and its point firmly buried in the tissues at the back part of this second nostril. By this device the divided septum is firmly held in its new position as shown by the diagram. The head of this pin will be just FIG. 356. inside of the anterior maris and must be allowed to remain for a week or ten days before it is withdrawn. It is often well to introduce a second pin from the external surface of the front of the nose just below the nasal bone. This aids in keeping the septal cartilage and bone in proper place. The second pin should have a flat head so that it may lie close to the surface of the nose and be covered with a small square of court plaster. Author's method of pinning Submucous resection of the septal cartilage nasal septum. and bony septum is the best method of curing nasal obstruction when due to a limited deflec- tion of the partition between the nares. The mucous membrane is incised and lifted up from the septum, so that a tenotome or small saw can be used to cut out the deflected cartilage and bone. The flap or curtain of mucous membrane is then allowed to drop over the opening in the Septum. - If the organ is greatly distorted by reason of old fracture, the soft tissues may, with a tenotome, be pared loose from the bones and the ex- ternal nasal structures be twisted into place after the septum has been divided and before the pin has been introduced. By proper pinning, the A BSC E SS OF T H E A N T R U M . 533 nose can often be kept in the median line and a fairly normal contour re-established. This operation is always very bloody and requires etherization. The pinning method is much better than the use of plugs to retain the parts in position, since they do the work more effectually and leave the nostrils free so that an antiseptic Solution can be used for washing out the nose during the period of inflammation after operation. The reconstruction of portions of the nose which have been lost is called rhinoplasty. The most common cause of this condition demand- ing such operative procedures is loss of the nasal structures from syphilis. A columella may be made by cutting a piece from the centre of the upper lip and turning it up, so that it may be sutured to the septal car- tilage and the tip of the nose between the two nares. An ala may be made by turning into the gap a flap dissected up from the cheek or upper lip. A tip of the nose, or even a new bridge may be constructed from the point of a finger which has previously been freshened, sutured to the nose, and kept in that position by gypsum bandages around the arm and head for several weeks. Total rhinoplasty may be effected by turning down a large flap from the forehead. This is called the Indian method of rhinoplasty in con- trast to the Italian method, in which a large flap is taken from the upper 8,I’DOl. ABSCESS OF THE ANTRUM. Suppuration within the antrum may be incidental to dental irritation, to tumor, to syphilitic necrosis, etc. One or more of the upper teeth may have their roots penetrating the antral cavity; hence caries, or other disease of such teeth, may lead to inflammation and suppuration of the mucous membrane lining the antrum. Suppuration occurring here, as it does, within a normal cavity, is properly called a purulent effusion. The pus, as a rule, escapes through the nose or through the diseased tooth- socket; hence, symptoms due to retention of pus in the quasi-abscess cavity are not very common. When the pus cannot escape, however, swelling of the cheek, protrusion of the eyeball, occlusion of the tear- duct, stoppage of the nostril, and bulging downward of the hard palate arise from this condition of the antrum, as in tumors occupying it. Sometimes the walls of the antrum are so thinned by the inflammatory process that pressure upon the cheek may develop crackling similar to that which occurs in cystic tumors of the lower jaw as well as in tumors of the upper jaw. Fluid within the antral cavity may sometimes be diagnosed by percussion on the cheek over the diseased bone, which will develop a percussion note different from that found over the bone on the Opposite side. When antral pus does not find vent through a tooth-socket or through the opening into the middle meatus of the nose, pointing may OCCur upon the cheek or in the roof of the mouth. The treatment of pus in the antrum consists in puncturing the bone below the upper lip above the canine tooth, or by extracting the tooth, if it is badly diseased, which seems to have its fang extending upward into the cavity of the jaw. The antral wall of the upper jaw is so thin that * can be perforated with a strong knife and treated. The cavity should then be washed out with carbolic or beta-naphthol solution. The opening in the bone should be kept patent by frequent washing by means of a *W*inge, and, possibly, by the continuous wearing of a metal stile or plug 534 RES PIR ATO R Y O R. G. A. N. S. so as to prevent, occlusion of the orifice made for drainage. During eating, a little piece of cotton may be put into the opening in order to prevent the entrance of food, if the retention of a stile or plug is not enforced. Suppuration, similar to that which occurs in the antrum, may at times occur in the mucous sinus of the frontal bone and require evacuation by trephining the bone at the root of the nose. DISEASES OF THE AIR-PASSAGES. CEdema of the Glottis. Swelling of the mucous membrane of the larynx or of the folds between the epiglottis and the arytenoid cartilages, due to inflammation or to dropsy, resulting from Bright's disease of the kidneys, may give rise to serious obstruction. This oedema of the glottis, when of an inflammatory kind, may arise from the inhalation of hot steam, the swallowing of acids and other irritating substances, insect stings, or to idiopathic laryngitis. The treatment of this condition, when asphyxia is too immediate to allow delay for medical remedies, is scarification of the swollen mucous membrane by means of a curved knife introduced through the mouth. The tongue, during the operation, can be held down by means of a tongue depressor, or by the finger of the Surgeon. Opening the larynx in the crico-thyroid space may be required to prevent suffocation in severe cases, which the surgeon fears to leave unattended between his visits. Fracture of the Laryna and Trachea. The laryngeal cartilages and rings of the trachea may be broken by blows upon the throat, as from a base-ball or in attempts at homicidal throttling. It is usually the thyroid cartilage which is severely fractured. In such injuries the vocal cords may be dislocated and death ensue, at once from asphyxia, due to spasm of the glottis. Suffocation may like- wise occur from hemorrhage, as a result of laceration of the mucous membrane lining the larynx. Such laceration will probably be indicated by the coughing up of bloody mucus. It is wise to perform tracheotomy in all cases of bad fracture of the larynx and trachea, because of the great danger of sudden death being caused by rapid inflammatory swell- ing of the intra-laryngeal structures, or to emphysema under the mucous membrane and in the tissues of the throat. The broken cartilage can at times be held in place by the application of adhesive plaster on the out- side of the throat. Better apposition, however, can be obtained by cutting down upon the injured cartilages and uniting them properly by means of catgut or silk sutures. Foreign Bodies in the Air-passages. Foreign bodies can gain entrance to the larynx and trachea only when the glottis is opened. Contact with the margin of the glottis induces instant spasm, which closes the chink and prevents admission of any intruding substance; hence, foreign bodies can only pass into the air- passages when the glottis is, as it were, surprised. Accordingly, foreign substances usually get into the air-passages when there is sudden, violent D IS E A SES OF T H E A I R - P A S S A. G. E. S. 535 inspiration made at a time when the patient is holding a pebble, a bean, or some such substance in the mouth. Coins thrown up in the air to be caught in the mouth sometimes slip through the chink of the glottis, Food and intestinal worms, which have been regurgitated or vomited into the upper part of the pharynx, may occasionally find their way into the larynx and trachea. Bodies so admitted into the air-tract may be caught between the vocal cords and detained in the larynx, or after passing be- yond this point may lie loose in the trachea or even get down into the bronchus. The right bronchus, being in a more direct line with the wind- pipe than the left, is the tube in which foreign bodies, going lower than the trachea, usually become lodged. Foreign substances impacted in the larynx at once give rise to violent spasm of the glottis, by which the patient may be immediately suffocated. The lividity of countenance, the gasping for breath, and the shrieks of the patient are followed by foaming at the mouth, insensibility, and Sud- den apnoea. If the foreign body is small enough to permit the passage of air alongside of it, death may not occur even if it is impacted in the larynx; and the first spasm of respiration, which has just been described, may subside and the patient regain consciousness. A phonia is character- istic of the impaction of such small foreign bodies in the laryngeal cavity. Spasm of the glottis in such cases occurs at irregular times, in any one of which death may take place. A period of irritation succeeds the obstruc- tive period, and is characterized by pain, coughing, and expectoration of blood-stained mucus. These irritating symptoms are especially prominent if the body has sharp edges, and occur when the foreign body is in the trachea and bronchus, as well as when it is impacted in the larynx. Bodies loose in the trachea may produce violent symptoms. They are liable to be coughed up against the lower surface of the vocal cords and cause spasmodic asphyxia, in which the fatal end may occur, or they may at such times become impacted in the larynx. The symptoms are similar to those already described. The patient is cyanosed, and often is more comfortable in the sitting posture than in the recumbent one. There is, perhaps, feebleness in respiratory sounds on auscultation, which is espe- cially marked on one side of the chest when the corresponding bronchus contains the foreign body. From the occurrence of secondary bronchitis Various ralés may be heard in the lungs. In some instances a peculiar Whistling or flapping sound may be perceived when the stethoscope is placed over the larynx or trachea, due to vibrations in the current of air produced by the foreign body. . The diagnosis in cases of obscure history may be made by auscultatory Signs, and by the fact that foreign bodies are liable to show difficulty in expiration, while croup and other obstructive diseases of the larynx show more difficulty in the performance of inspiration. Laryngoscopic exami- *tion will often reveal the presence of a foreign body entangled in the folds of the mucous membrane lining the interior of the larynx. TREATMENT—It is not usual for foreign substances within the respi- *atory tract to be spontaneously expelled. They may remain for many *onths, and cause, as a secondary result, hemorrhage, ulceration, abscess, chronic disease of the lungs, and fatal exhaustion. The danger of fatal *P*m of the glottis occurring suddenly renders it important that the *hea should be opened, as a precautionary measure, as soon as it is determined that a foreign body is lodged therein. The habit indulged in Y Some of inverting the patient and slapping him upon the back in order that the offending substance may be expelled is dangerous, and should 536 R E SPIR A TO R Y O R. G. A. N. S. never be attempted until after the trachea has been opened, since impac. tion of the body upon the lower surface of the glottis may cause imme. diate asphyxia. . Anything impacted in the larynx may possibly be removed by the laryngeal forceps with the aid of a laryngoscope. In such instances, of course, tracheotomy is not required, although the sur- 9eon should be prepared to plunge his knife into the crico-thyroid space, and admit air to the Suffocating patient, in case his manipulations cause spasm of the glottis. - º Where extraction through the larynx and mouth is impossible, the thyroid cartilage should be laid open by a median incision, and carried upward after a puncture has been made in the crico-thyroid membrane. The offending body should then be removed with the least possible lacer. ation of the mucous membrane. A tube should be left in the wound for a day or two until all danger of inflammatory swelling within the larynx has passed. When the body lies in the trachea or bronchus, tracheotomy should be performed instead of laryngotomy, subsequent to which the mucus in the tube should be coughed up by the patient, or sucked out by a syringe or aspirator in the hands of a surgeon. The patient should then be inverted and permitted to cough in the hope that the foreign body may be expelled. - Search for the latter may be undertaken by means of the forceps intro- duced carefully through the wound. If it is not found the sides of the wound should be stitched to the skin, in order that extrusion may be per- mitted by subsequent effort at coughing. The patient should be kept in a room whose temperature is not less than 80° F., and the air of which is kept moist by a steam atomizer or similar device. The foreign substance may be so fastened in the trachea or bronchus that its expulsion may not take place until several days have elapsed; at which time it is not impos- sible that masses of exudate, similar to that found in croup and diphtheria, may also be expelled. When the foreign body has made its exit, it is wise to leave the wound open for a few days lest inflammatory swelling should impede respiration. This is scarcely necessary, however, except in those cases in which the foreign body has become impacted in the larynx, because a considerable amount of swelling may take place in the trachea without obstructing respiration. In rare cases a body lodged in the larynx may be removed better by opening the pharynx between the hyoid bone and the top of the larynx. TUMoRS OF THE LARYNx AND TRACHEA. Tumors of the trachea, as primary growths, are exceedingly rare; but in the larynx various primary tumors occur, and are sometimes called laryngeal polypi. Laryngeal tumors cause symptoms similar to those induced by the presence of foreign bodies in the larynx. The forms most commonly found are papilloma, epithelioma, fibroma, adenoma, and myxoma. These may be pedunculated or sessile, and, if malignant, ulti- mately involve the lymphatic glands and other structures of the neck. Tuberculosis of the larynx occurs, and at times resembles epitheliom: atous disease. Laryngeal tumors grow slowly and attain considerable bulk, for the location, before marked symptoms occur. Their presence is to be detected by the laryngoscope; and, if small, they may be removed by the forceps, snare, cautery, or laryngeal guillotine. In cases where there is great tendency to spasmodic dyspnoea, due to irritation from the intrº T U M O R S OF T H E L A R Y N X. A N ID T R A C H E A . 537 laryngeal condition, precautionary tracheotomy may be required, as when foreign bodies are impacted in the glottis. When a tumor located within the larynx cannot be removed through the mouth, in the manner described, it becomes necessary to do the opera- tion called thyrotomy. Thyrotomy, or splitting the thyroid cartilage, in the middle line, is accomplished by incision of the skin over the larynx, by which the thy- roid cartilage and crico-thyroid membrane are exposed. The crico-thyroid space is then FI (; . .357. opened with a knife, and the incision carried gº upward through the thyroid cartilage almost §º to its upper margin. It is important not to split the entire cartilage into its two halves, but to leave a portion of it at its upper border intact, in order that the lateral halves may retain their relative position after the tumor has been removed and the sutures applied. §§ §§§ During this operation the head of the patient ºft should be thrown well back, in order to make §§§ the laryngeal region prominent. When the Zºº Yº larynx has thus been opened by external ś incision, its interior may be examined, and . ; any growth removed by means of forceps §§ and scissors. The cartilaginous tissues are º then sewed together with fine catgut, and the external parts sutured and dressed in the ordinary manner. A solution of cocaine should be used to prevent pain during the removal of such growths through the mouth ; and it may even give sufficient anaesthesia for the operation of thyrotomy, if it is in- jected under the skin about the line of the proposed incision. Papilloma of larynx. (TREVEs.) A pharyngotomy between the hyoid bone and the larynx may, at times, afford a good route for the extirpation of laryngeal tumors. Epithelioma of the larynx requires removal of the larynx, called laryngectomy, which should be done in all cases, where the diagnosis is clear, at an early stage of the disease. The larynx is removed by means of an incision in the middle line of the neck from the hyoid bone to the third ring of the trachea. The thyroid body should be drawn downward *Way from the field of operation. The trachea is then separated from the Surrounding structures, and divided transversely at the level of the second *g. The lower portion of the windpipe is next plugged with a tampon of gauze or sponge, through the middle of which passes a large tube by Which the air and ether vapor are admitted to the lungs. This plugging prevents the blood flowing from the seat of operation into the air-passages. !he larynx must now be freed from the tissues on either side, separated from the hyoid bone above and the pharynx behind, and thus totally *moved. The enucleation being thus completed, the radical extirpa- tion of the epitheliomatous tissue is accomplished. After the Superior laryngeal arteries and other vessels have been tied, the dressing, consisting of antiseptic gauze, is packed into the cavity left by the removal of the larynx. Subsequent to the operation the patient 538 R E SPI R A TO R Y O R. G. A. N. S. is nourished by enemata or through an oesophageal tube until the wound has cicatrized, while respiration is carried on through the lower portion of the trachea. After cicatrization has been accomplished, an artificial larynx can be adopted and the patient given a certain amount of speech. TRACHEOTOMY. Tracheotomy, or opening of the windpipe, may be required to prevent Suffocation in cases of obstruction in the larynx. Such obstruction occurs in the membranous inflammation which takes place in croup or diph- theria, in the occluding swelling of tubercular and syphilitic laryngitis, and in the spasm of the glottis which arises from foreign bodies or tumors in the air-passages. Cicatricial narrowing of the larynx may remain after the cure of syphilitic ulcers, and may cause obstruction demanding trache- otomy. When there is danger of asphyxia, it is wisdom on the part of the surgeon to open the windpipe before the patient's strength has been exhausted by dyspnoea. The operation, if properly done, is not at all a serious one, provided it is performed at a time when the symptoms do not require haste. Many of the accidents which accompany the performance of tracheotomy are due to its postponement until the patient is moribund; hence arise many of the complications to what is other- wise a comparatively simple operation. When the surgeon divides two or three rings of the trachea, the opera- tion is called tracheotomy; when he divides the crico-thyroid cartilage and the crico-thyroid membrane, or only one of these structures, the operation is termed laryngotomy. If the lower portion of the larynx and the upper part of the trachea are opened, the operation is called laryngo-tracheotomy. $ Etherization may be dispensed with in many cases, since the painful part of the operation is in the cutaneous incision, which may be ren- dered painless by hypodermic injections of cocaine. The sense of pain is practically absent, moreover, in conditions of imminent suffocation from prolonged laryngeal obstruction. I myself, however, nearly always prefer general anaesthesia, especially in infancy, since movement of the child, even if it suffers but little pain, interferes with the operation. When the trachea is to be opened, the patient's shoulders should be raised by thrusting a pillow under them, and the head thrown back sº as to put the neck on the stretch. A median incision is then carried from the crico-thyroid space almost to the sternum. Its length depends upon the thickness of the neck and the consequent depth at which the trachea is situated. The veins, swollen because of interference with respiration on account of the patient being in a state of asphyxia * the time of operation, should be avoided if it is practical. Their division, however, is not a matter of serious moment, since, they stoP bleeding as soon as respiration is reëstablished. The dissection is Con- tinued in the middle line, through the deep fascia and between the sterno-hyoid muscles, until the thyroid gland is exposed. The isthmus of this body should be pushed downward, or drawn upward, according as the surgeon intends to open the trachea at the lowest accessible point or in a higher position. When the isthmus, on account of iº size, cannot be displaced, a ligature should be tied around it on each side in order to prevent hemorrhage, and midway between these liga- tures it should be divided. The windpipe can be recognized by its T R A C H E O TO M. Y. 539 white color. A tenaculum is hooked into the tracheal wall to steady it, a sharp-pointed knife then thrust into the windpipe, and two or three rings divided in an upward direction. The incision must, of course, correspond with the median cutaneous incision, in order that the open- ing in the windpipe may not be closed by the overlying tissue covering it after the surgeon has permitted the trachea to slip from the tenacu- lum. It is very important that no blood should get into the trachea by the first inspiratory effort after the opening is made, and from thence be carried into the bronchi. Such inhalation of blood may suffocate the patient. . In some cases, it may be impossible to stop all bleeding before the tracheal cut is made; therefore, the patient should be turned upon his face with his head over the edge of the table, and retained in this position while the opening is made. . The blood will then flow out of, instead of settling in the bottom of, the wound. The danger of its being sucked into the air-passages will thus be averted. As soon as the rings have been divided, it is well to thrust a pair of forceps into the trachea in order to hold the lips of the wound apart. In this manner FIG 35S. a supply of air is at once given to the patient, and the false membrane or mucus which has obstructed the respiratory passage, can be removed. It may be necessary to wipe out such obstructing material with a feather or camel's-hair pencil passed into the windpipe, or to suck it out by lmeans of a catheter to which an aspirator or a syringe has been at- tached. In diphtheritic cases it is dangerous and foolish for the surgeon to suck out such membrane with his mouth, since fatal consequences to the operator have often followed this practice. After the trachea has been cleared, a tracheal tube may be inserted in order that the respiration may go on without obstruction from falling together of the lips of the wound. A tracheal tube consists of a double canula, the inner one of which projects at the internal end a little beyond the outer one. The object in having two tubes is to enable the attendant to remove and clean the inner tube, as it becomes plugged With mucus or dried secretions, while he leaves the outer one in the wound in ºrder to make replacement of the inner tube easy. The outer tube has flanges upon each side, by which it is held in place by means of tapes and tied around the neck. I prefer, however, to fix these Wings or flanges by means of sutures carried through the neighboring skin with a needle. The upper and lower angles of the Qutaneous wound may be sutured after the tube FIG. 359. has been inserted. There are several forms of tracheal - dilators made which are preferred by some operators to the canula. ºn diphtheritic patients less skilled nursing is re- ſºired if, instead of introducing the canula, the sur- $99, Cuts out a small rectangular portion of the trachea and Stitches the edges of the tracheal opening Tracheal dilator. * º skin. The tube requires constant watching, l º be kept free from obstruction by dried membrane, secretion, or 990, by the frequent passing of a feather through it. In diphtheritic Trachea tube, with valve. 540 R E S P J R A TO R Y O R G A N S , cases the inner tube should be removed and cleaned about every two hours, and both tubes should be removed if there are any evidences of serious obstruction. The patient, whose windpipe has thus been opened, cannot talk unless the orifice in the throat is closed by placing a finger over the tube, or in some way preventing respiration through the anterior orifice. In four or five days after the operation for diphtheria it is proper to make an attempt to dispense with the tube; but if symptoms of laryngeal obstruction still remain, the tube must be reinserted for a few days longer. It is essential that the patient upon whom tracheotomy has been done should be kept in a hot room with a moist atmosphere until the symptoms for which the operation was done have subsided, since bronchitis or pneumonia are very liable to occur from inspiration of cold, dry air. Inhalation of dust should be prevented, if possible, by keeping a piece of mosquito-netting in front of the opening in the throat. This, however, is often impossible in opera- tions for diphtheria where there is frequent necessity for cleansing the tube. The temperature of the room should be kept at 75° or 80° F., and the air should be kept moist by means of an atomizer, or by a wet blanket suspended in the room before a fire. The interior of the trachea and the wound may be mopped with a solution of sodium carbonate in glycerin, or with a solution of pepsin or of trypsin, in order to facilitate detach- ment of the false diphtheritic membrane. It has been suggested that, after tracheotomy for diphtheria, the windpipe above the seat of operation may with benefit be plugged with sublimate gauze (1:2000). A quick tracheotomy may be done in emergency cases by grasping the larynx between the thumb and forefinger of the left hand and steadying it in this manner, while a rapid incision is made with the right hand in the middle line. In still greater emergency air may be admitted to the lungs by plunging a knife through the crico-thyroid space, which is easily felt as a depression about three-quarters of an inch below the most prominent point of the Adam's apple. An opening thus made will permit air to enter in sufficient quantity until a more systematic operation can be done. I have operated in this manner by means of an ordinary pocket-knife, which is usually always obtainable. Where it is impossible to obtain a proper tracheal tube, a piece of a drainage-tube will tem- porarily answer the purpose. If the patient has stopped breathing by the time the surgeon has gained an entrance to the windpipe, artificial respira: tion can possibly be started by blowing into the tube with an ordinary syringe or a pair of bellows. It is wise always to introduce the largest size canula that the trachea will hold. It must not be so large, however, as to strip up the mucous membrane as it is pushed down into the wind, pipe. A slight alteration as to its length or shape, and also its removal from time to time, are desirable, because the pressure exerted by its internal end may induce ulceration of the lining membrane of the windpipe. The lobster-tail canula, with a blunt pilot for its introduction, is a favorite one with me. In cases of stenosis of the larynx in which the tracheal tube must be constantly worn, a tube with an opening in the intratracheal portion will enable the patient to expire through the larynx and to talk with Cº. parative ease. If the tube has not this opening, and it fits tightly so that no air passes above the opening, speech is impossible. The point at which an opening in the air-passages should be made depends upon the condition for which the operation is done. In diphtheº" it is best to go as low down as possible; hence, a point below the isthm." T R A C H E O TO M Y. 541 of the thyroid gland is probably the best place under such circumstances. In tracheotomy for chronic disease of the larynx, a high tracheotomy above the thyroid body is efficacious and makes a less difficult operation. FIG. 360. Double tracheal tube (lobster tail). Intubation of the Laryma. The introduction of a metal tube into the chink of the glottis and its retention there for a period varying from several hours to several days, is called intubation, and is in certain cases a good substitute for the more serious operation of tracheotomy. Though especially employed in cases of diphtheria and oedema of the glottis, it is possible that it may be of advantage in cases of foreign bodies in the trachea, because it will prob- ably prevent fatal asphyxia from spasm of the glottis, due to such foreign body being coughed up against the lower surface of the vocal chords. In such a condition intubation would seem to be of service as a temporary measure until arrangements can be made to open the trachea for extraction of the foreign substance. Intubation, which is seldom required in adults, is performed with the Child held in the nurse's arms without being etherized. A gag is placed between the teeth on the left side of the mouth in order to hold the jaws *part, and an assistant holds the patient's head well back. The surgeon introduces his left forefinger into the mouth and by pressing down the tongue he is enabled to guide the tube with his right hand into the glottis. After it has been so introduced the detachable handle or obturator is re- moved. The patient then breathes through the tube, which is kept in place by reason of its shape. At the top of the tube is a flange to pre- Nºt the instrument slipping into the trachea, and in this flange is a small hole through which a long thread is passed before any attempt at intro- 542 R E SPI R A TO R Y O R. G. A. N. S. duction is made. The ends of this thread hang from the mouth and are used to remove the instrument from the pharynx if it is found not to be properly placed when the detachable handle is withdrawn. If, however, the surgeon finds the patient breathing well and the tube properly placed the string is withdrawn and the instrument left in position. If all goes well the tube may be left in position for several days. When its extrac. tion is desired an instrument called by Dr. O'Dwyer the extractor is introduced. This instrument is operated by expanding two blades or jaws after its point is introduced into the calibre of the tube, thereby giving the surgeon control of the latter and enabling him to withdraw it quickly. During the introduction and withdrawal of the laryngeal tube respiration is entirely arrested for a moment. An advantage of intubation is that the consent of the patient's family can be more readily obtained for the performance of the operation than is the case in tracheotomy, which causes bleeding, and therefore seems to them more undesirable and dangerous. The objections to intubation are that the tube may slip into the trachea, that it may be swallowed, and that food gets into the air-passages, thus causing at times secondary pneumonia. It has been supposed by some that there is danger that the false membrane of diphtheria may be pushed down into the trachea by means of the tube, thereby increasing the res- piratory obstruction. This objection, however, applies equally to the insertion of a tube after tracheotomy. Intubation, moreover, does not prevent tracheotomy being performed later, if the necessity for it arises. Attempts have been made to correct the difficulty of feeding after intu- bation, by attaching a sort of artificial epiglottis to the upper end of the tube. Intubation is a valuable addition to the surgeon's resources, for which the profession owes much to Dr. O'Dwyer; but is often inferior to the more radical operation, tracheotomy. DISEASES OF THE CHEST. Contusions and Abscesses. PATHOLOGY AND SYMPTOMS.–Contusions and abscesses of the chest wall require no special description other than to say that abscess of the chest wall is occasionally secondary to purulent effusion in the pleural cavity or to abscess of the lung. Contusion or rupture of the lung tissue may occur without laceration of the pleura. These lesions probably take place because the lung is sub- jected to blows or concussions when the vesicles are filled with air and the glottis closed, so that the air within the lung tissue cannot be forced out at the time the force is applied. The symptoms of this condition are spitting of blood, diaphragmatic breathing, dyspnoea, cough, bronchial råles, and signs of localized pneumonia, or pleurisy. These symptoms vary with the extent and location of the injury. Emphysema may occur between the lung and the pulmonary pleura, and the air so extravasated may find its way into the mediastinum and upward into the cellular tissue of the neck and back. If the pluera is torn by the injury, blood and air may escape into the pleural cavity and produce haemo-thorax or pneumo-thorax with their characteristic physical signs. Pulmonary abscess, or gangrene, and mediastinal abscess are occasional I) IS E A SES OF T H E C H E S T . 543 sequences of lung injuries. Gunshot and stab wounds of the lung are not infrequent ; and laceration of the periphery of the lung may happen as a complication of fracture of the ribs. Laceration may occur from puncture of the lung by one of the fragments at the time the fracture of the rib is received, though subsequently no displacement of bone may be discoverable, because the resiliency of the chest wall has brought the fragments of bone into apposition. The symptoms of such wounds of the pulmonary tissue are similar to those described above as occurring from contusion and rupture of the lung. Subcutaneous emplºysema is a very common concomitant of frac- ture of the ribs when one of the fragments has injured the lung. In such instances the air in the vesicles escapes into the pleural cavity, and then during expiration is pumped through the opening in the costal pleura into the subcutaneous cellular tissue. It must be remembered that the lung extends downward at the lateral and posterior aspects of the chest to about the level of the tenth rib, while the pleural cavity extends as far downward as the twelfth rib. In a wound of the chest below the tenth rib, therefore, the pleura alone will probably be wounded, and not the lung. If a penetrating wound extends sufficiently deep to traverse the pleural sac, puncture the diaphragm, and enter the abdominal cavity, the organs contained in the abdomen may suffer injury from the bullet or knife in addition to the damage sus- tained by the pleura. The arching upward of the diaphragm renders it possible for a penetrating injury, even higher than the tenth rib, to pro- duce lesions of both the thoracic and abdominal viscera. When the wound of the chest wall is a comparatively large one, its communication with the pleural sac is often to be recognized by the sucking and hissing sound produced by the air entering the chest during respiration. If a large vessel in the lung is wounded, the bronchial tubes may be so filled with blood as actually to drown the patient. Pulmonary wounds heal like other wounds if protected from suppura- tion and putrefaction. The air entering the pulmonary tissue through the trachea is freed from pathogenic germs to a great extent by the filter- ing process which it undergoes before it reaches the seat of the wound; hence, if the chest wound be kept aseptic, there is little danger of suppu- ration or septic pneumonia or pleurisy. Protrusion of a lung may occur at the cicatrix of a large wound in the chest wall. TREATMENT.-The external bleeding in chest wounds is usually not Very severe, and needs no special treatment. If the blood comes from the lungs it will probably be frothy and in greater quantity during expi- ration than in inspiration. The flow of blood into the pleural sac, which occurs at the same time or before escaping from the chest through the external opening, will probably soon make sufficient pressure upon the lung to stop the bleeding from the pulmonary tissue. The blood so enter- ing the pleural cavity will, if kept aseptic, subsequently be absorbed; if not kept antiseptic, it will break down into pus and cause traumatic empyema. Severe hemorrhage may supervene from wounds of the intercostal and nanºmary arteries. The intercostal arteries lie in grooves at the inner and lower margins of the ribs. Hemorrhage from one of these vessels *y be stopped by seizing the bleeding point with a hemostatic forceps, Which may be left in position for several hours. If arrest of hemorrhage ...this, means be impossible, the surgeon may perhaps be able to scrape off, with a blunt instrument, the periosteum from the bottom of the inter- 544 R. E SPIR. A. T O R Y O R. G. A. N. S. costal groove. This procedure separates the vessel from the bone, and makes its ligation practicable. Another method is to push into the wound the centre of a square piece of antiseptic gauze, and, after distending it like a small bag within the chest, to stuff the pouch so made with small pieces of antiseptic sponge or gauze. By seizing the projecting corners of the square of gauze and drawing the intrathoracic mass firmly against the internal surface of the ribs, pressure is made upon the intercostal vessel and bleeding prevented. Resection of a portion of the rib is seldom necessary to gain control of the vessel from which hemorrhage OCCUl I’S. Ç The internal mammary artery runs parallel to the border of the sternum, and from a quarter to half an inch external to this margin. Bleeding from a wound in the internal mammary artery should be treated by ligation or by seizing the bleeding point with a hemostatic forceps, which should then be left in position with antiseptic dressing packed around it. As a rule, little information is obtainable by the introduction of probes into a chest wound. There is no objection to their use, if they are em- ployed with caution and antiseptically. When the wound is large enough to admit the surgeon's finger, which, of course, must be aseptic, a clear understanding of the nature of the injury is often obtained. The subcutaneous emphysema which is sometimes present in lung injuries, is recognized by the elastic swelling of the skin, which crackles when pressed upon by the fingers. This tumefaction, which is free from any discoloration such as occurs in cutaneous inflammations, occurs during the first few hours after injury, and afterward subsides gradually without treatment. Antiseptic cleansing of the wound, the introduction of sutures, and the application of dressings, fulfil the local requirements of the thoracic wounds. In order to keep the chest at rest as much as possible, a firm bandage should then be applied. If suppuration occurs in the pleural cavity, the wound must be thoroughly opened, a drainage-tube inserted, and antiseptic irrigation carried on in the manner discussed under Pleural Effusion. If the traumatic pneumonia is very acute and exten- sive, venesection may be the only means to preserve life. In other cases secondary pneumonia and pleurisy should be treated by ordinary medical means. The fact that persons subjected to accidental wounds of the chest are usually in a good state of health, and that, therefore, the intrathoracic inflammation is of a sthenic type, indicates that active depressants and purgatives are more often ncessary than in cases of idiopathic pneumonia and pleurisy. The diagnosis of the inflammatory conditions within the chest is made, of course, by the ordinary rules of auscultation and per- cussion. Bullets and other foreign bodies, unless their location is definitely de- termined, and found to be accessible to the knife without adding much to the original injury, should be allowed to remain imbedded in the tissues. They often become encysted, and do no harm. If subcutaneous abscess or a sinus indicates their position, the surgeon is justified in undertaking operative search. Under such circumstances I have recently successfully removed, after resection of the ribs, a piece of silver drainage-tube from a young child's chest, where it had been for many months, after having become lost during treatment for idiopathic empyema. su RC, ICAL TREATMENT OF P L E U R AL EFF USIONS. 545 SURGICAL TREATMENT OF PLEURAL EFFUSIONS. Aspiration of the pleural cavity or thoracentesis is performed in serous effusion into the pleural cavity (hydrothorax). Incision of the chest wall with the introduction and retention of a drainage-tube into the pleural sac is the proper surgical treatment in cases of purulent effusion into the pleural sac (empyema). In hydrothorax aspiration should be done com- paratively early, or as soon, at least, as medicinal remedies do not produce any marked diminution of the quantity of fluid in the cavity. Incision and drainage should be performed as soon as the existence of pus is deter- mined. Aspiration should be done with a hollow needle, and one of the forms of aspirating pumps. Care should be taken that no air enters the chest, and that the lungs and other structures of importance are not injured by the point of the needle. If an aspirator is not obtainable an ordinary trocar and canula is used. A long, rubber tube, however, should be attached during the first flow of serum, immediately after the trocar has been withdrawn, and the end of this tube placed below the surface of a solution of carbolic acid (1:20). This precaution is taken to prevent the sucking up of air into the chest when the flow of serum becomes intermittent as the cavity is nearly evacuated. Thoracentesis does not require general anaesthesia. If the patient is very sensitive to pain the skin at the point of the proposed puncture may be benumbed by a spray of ether or rhigolene, by a hypodermic injection of cocaine, or by the application of ice and salt. The best position for the patient is a semi-recumbent one, which can be changed during the operation to a recumbent one, as he becomes weak. The place to insert a puncturing instrument is in the sixth interspace close above the upper border of the seventh rib and in a line with the middle of the axilla. If careful auscultation and percussion indicate the presence of a localized pleural effusion it may be necessary to select another spot; since it is evident that a cavity containing fluid should be tapped near its lower wall, as this gives the best opportunity for entire evacuation of its contents. As soon as the aspirating needle enters the pleural sac the flow of serum is evident in the glass tube near the needle, or in the bottom of the aspirator. The escape of fluid should be at first somewhat controlled, in order that sud- den evacuation of the contents of the pleural cavity may not lead to Syncope. It is also wise occasionally to stop the flow for a moment. The occurrence of cough is an indication to desist temporarily; while a dis- Charge of blood through the needle means that the lung, or some vessel, has been injured, and suggests the partial withdrawal of the instrument. When the fluid ceases to escape the operation is concluded by drawing out the needle, unless it is believed from the physical signs that the calibre of the aspirator has been plugged by a mass of lymph sucked into the tube. This complication is, as a rule, indicated by a sudden, rather than a gradual, cessation of the flow. It may be possible, by changing the cur- *ent in the aspirator, if the instrument permits such a procedure, to force the lymph back into the chest. If this is impossible it may be necessary . Withdraw the needle, remove the obstruction, and puncture in a new place. An antiseptic pad should be placed over the opening after the operation * performed, and the patient treated by medical means as previ- ously. Drainage of purulent effusions in the pleural cavity is accomplished by 35 546 R. ES PIR. A. T ORY O R. G. A. N. S. making a two-inch incision in one of the intercostal spaces just above the upper border of one of the ribs and parallel to the rib. This site is chosen for aspiration and incision, because the intercostal artery runs along the lower edge of each rib. If there is any doubt about the possi- bility of the space between the ribs being sufficiently large for the sur. geon's purpose, the initial incision had, perhaps, better be made in the middle of the intercostal space, rather than close to the upper border of the lower rib. The sixth interspace is, as a rule, a good place for incising the pleura. If there is any evidence of the pus collection being localized the surgeon would naturally make his incision a little below the centre of the area of dulness. As the patient after such an operation lies upon his back, the incision should be made about an inch behind a line downward from the middle of the axilla. The cutaneous incision should be suffi- ciently large to permit a good size tube to be introduced. If the space between the ribs is not sufficient a portion of the lower rib should be excised. It is not often necessary to remove a section of the entire width of the rib, as a semicircle cut out of the bone with bone forceps or saw will usually give sufficient space for the tube. My own experience has shown that excision of the rib for this purpose is seldom required. If, however, it seems necessary to remove a section of the entire width of the rib the operation should begin by an incision over the middle of the rib; after which the periosteum should be detached and about an inch of the rib sawed out. The intercostal artery in such an operation should be secured before the pleura is opened. After the dissection has been carried down to the pleura and hemor- rhage stopped, if there be any, the pleura should be laid open to the full extent of the external wound. The surgeon's finger can then be inserted, the interior of the chest explored, and any bands of lymph that divide the pleura into separate cavities broken up. Etherization is not essential in this procedure, as the pain is not very much greater than that of aspi- ration. Local anaesthesia is sufficient. A rubber drainage-tube without side holes and with a calibre of about one-quarter of an inch should be introduced about an inch into the pleural cavity and stitched to the skin by wire or silk sutures. After the extremities of the wound have been drawn together with sutures, a voluminous antiseptic dressing should then be applied. The pleural cavity should be washed out with a solution of carbolic acid (1:40), betanaphthol (1:4000), salicylic acid or boric acid once in twenty-four hours. These disinfectant solutions are introduced by hydrostatic pressure, obtained by attaching to the drainage-tube an- other tube or pipe coming from a reservoir held about two feet above the patient. As soon as distention of the cavity by the fluid produces pain the supply-tube should be detached, or the reservoir lowered so that the mingled pus and antiseptic solution may escape. One or two pints of fluid may be introduced into the chest at one injection, and it may be repeated until the outflow is very little stained with pus. Irrigation and drainage in this manner should be continued for several weeks, and should not be discontinued until it is evident that the cavity within the chest has greatly contracted, and there is very little purulent collection; When this occurs the drainage-tube may be withdrawn and the wound allowed to heal by granulation. Too early withdrawal of the tube mºſ permit re-accumulation of the pus, and necessitate a second operatiºn, ſº order to relieve the septic symptoms which are liable to occur. If the fistulous opening, left after the drainage-tube is withdrawn, remains for many months, further treatment will be required. The condition is, * I) ISE A S E S OF T H E N E C K . 547 rare instances, due to a broken portion of the tube having been left within the chest ; but is more apt to happen because the drainage has not been complete, or because the tube has been withdrawn too early. Dila- tation of the fistulous track by the introduction of a sponge tent, or a piece of compressed sponge, will often permit reëstablishment of irrigation and thereby induce cure. In other cases it may be necessary to lay open the sinus and resect a portion of a rib in order to obtain free drainage. In some cases healing of the pleural cavity is prevented by the fact that the pus sac will not collapse because of inflammatory thickening and adhesions. Under such circumstances it has been advocated that two or three inches of several contiguous ribs be excised in order that the chest wall becoming flaccid may fall inward, and by coming in contact with the pulmonary wall of the pus sac cause the cavity to become oblit- erated. In performing this operation it is well to dissect away the thick- ened costal pleura. PULMONARY ABSCESS AND GANGRENE. The operative treatment of pulmonary abscess consists in cutting into the lung, after having incised the chest wall and pleura, in order to evac- uate the pus confined in the lung tissue. Before such an operation is attempted the most careful physical diagnosis must locate the abscess, and even then it is wise to confirm the physical signs by introducing an aspi- rating needle or trocar into the lung. When such abscess has been dis- covered incision of the external tissues and lung is proper, and should be followed by the insertion of a large drainage-tube so that irrigation may be carried on. Excision of a gangrenous portion of the lung has been attempted after opening the chest. The difficulties in diagnosing the po- sition of the gangrenous area are similar to those met in diagnosing the position of an abscess. MEDIASTINAL TUMoRS AND ABSCESSEs. Pus in the anterior mediastinum may be evacuated by an incision between the costal cartilages, or by trephining the sternum. Such a pos- sible condition should be given consideration when the surgeon is investi- gating any obscure case of thoracic disease. Tumors of the mediastinum should also be remembered in this connection. DISEASES OF THE NECK. Wounds of the neck should be treated as other wounds. If the trachea or glottis is opened the parts should be brought together and sutured and POVision made for drainage. Severe wounds of these structures are ºften made in suicidal attempts. After the parts have been sutured an *ophageal tube may be required for feeding the patient. If the tongue º “piglottis has been cut loose from its attachments it may cause asphyxia by falling upon the opening of the glottis. Sudden oedema of the glottis *Y arise as a complication of wounds of the larynx. These complica- {ions may render it necessary for tracheotomy to be performed, lest *Ween the visits of the surgeon death may occur from sudden swelling 548 R E SPI R A TO R Y O R G A N S. or rather obstruction of the chink of the glottis. Emphysema of the neck may supervene after such wounds by reason of air escaping from the respiratory tract into the subcutaneous tissue. Diffuse cellulitis of the neck may follow wounds; and septic poisoning, secondary to ulcera- tions in the mouth or pharynx, to Scarlet fever, and to diphtheria, is not uncommon. If the cellulitis assumes a suppurative character free inci- sion to prevent burrowing of pus, and antiseptic irrigation of the cavities in which this is located, are urgently demanded. Congenital cysts, called hydroceles of the neck, are due to the embry- onic clefts not becoming entirely closed. A cavity is consequently left which is filled with fluid. A most common surgical condition, however, in this situation is glandular enlargement due to chronic lymphademitis. These chronic lymphatic conditions are often the result of tubercular in- fection and are very liable to become caseous and to break down into puriform fluid. Acute lymphadenitis often arises as a complication from diseased teeth. A lymphatic glandular enlargement situated over the submaxillary or parotid salivary gland sometimes acquires considerable bulk, and is liable to be mistaken for tumor or malignant disease of the salivary gland. Chronic enlargement of the lymphatic glands of the neck should be treated by constitutional remedies, such as tonics, cod- liver oil, potassium iodide, a residence at the seashore, and attention to hygienic surroundings. Locally the treatment should consist of counter- irritation by means of iodine tincture or the ointment of the red iodide of mercury. If after such measures they continue to enlarge it may be proper to excise the glands before they have undergone puriform change. This is desirable because they may become the primary focus from which general tubercular infection may arise. If cheesy or puriform degenera- tion has taken place it is proper to incise the skin over the softened mass, to scrape away with a curette all the glandular tissue and diseased struc- ture around it, and to dress the wound with iodoform. The depressed scar left by such early incision is less deforming than the irregular and puckered superficial cicatrix which usually remains after spontaneous evacuation of the puriform collection. The unsightly scars left by the occurrence in youth of such cervical tubercular lesions may be made almost imperceptible by a small plastic operation. An elliptical incision is made around the depressed cicatrix, the skin is dissected loose for some distance on each side, and the edges are then drawn together by sutures over the intervening depressed pol- tion of skin, which has previously been made raw by scraping with a knife edge. Thus the cutaneous structures are elevated to a level with the surrounding skin, and the irregular scar converted into a straight, white line. DISEASES OF THE THY ROID BODY. The function of the thyroid gland is probably control of the mucinoid substances in the tissues, the regulation of albuminoid metabolism, and the manufacture of blood corpuscles. Its atrophy or entire removal is followed by the condition called myxoedema. (Fig. 362.) In myxoedema the subcutaneous tissue of the patient becomes swollen with mucus. This causes a condition resembling serous oedema, except that the tumefac. tion is harder. The patient's lips and eyelids become puffy, his mind heavy, his speech thick, the temperature usually subnormal and his intel- ligence deficient almost to a condition of imbecility. There is loss of the B R O N C H O C E L E O R. G. O IT R. E. 549 red and increase of the white corpuscles of the blood. The condition, as far as known, is unamenable to treatment, and is finally fatal. It has been attributed also to changes in the sympa- thetic nervous system. The defective FIG. 361. mental state, called cretinism, found at times with goitre, is probably due to the goitrous affection causing atrophic inter- ference with the function of the thyroid body. BRONCHOCELE OR GOITRE. * * * * ~ Tumors of the thyroid body are usu- º ally included under the head of bron- %. “ º o e º §§§ºğ chocele or goitre, although in a strict || º º *N sense the term should probably be em- ſº \{{=º jloyed for enlargements of the gland and tº / Sº | º ploy * *-rºsſ tº tº not to its infiltration or substitution by morbid growths. The thyroid gland in Myxoedema. (TREVES.) women not infrequently becomes enlarged from congestive swelling during sexual excitement, pregnancy, and at menstruation. The congestive enlargement so occurring may remain after the causative factors have passed away. The enlargement may include both lobes of the gland as well as the isthmus, or it may involve either lobe or the isthmus alone. At times pulsation occurs in the enlarged gland and is so evident as to simulate aneurism. In one variety of congestive goitre there is protrusion of the eyeballs and irritability of the heart associated with the enlargement of the thyroid body. This condition is a distinct general disease called exophthalmic goitre. In this affection the thyroid gland is swollen, perhaps tender on pressure, and may pulsate. The eyeballs protrude from between the eye- lids, as a result, probably, of vascular congestion in the post-ocular tissue, and the heart's action is irregular and feeble. Often there is a murmur heard at the cardiac base. The patient is weak, anaemic, and often sub- ject to anorexia and amenorrhoea. Gradual improvement usually takes place under effective treatment lasting through many months. Cases, however, do at times end fatally. In addition to the congestive enlargement of the thyroid body, which has been described, simple hypertrophy of the stroma and glandular elements of the organ may occur. Fibrous and cystic changes also take place in this organ, giving a form of goitre corresponding to these alterations. Simple hypertrophic goitre, which is really a fibro-adenomatous change, may follow the congestive form. The patient presents symptoms not unlike those of exophthalmic goitre, except that the ocular and cardiac Symptoms are absent. Interference with swallowing and respiration may 0CCur, as the position of the growth may produce pressure upon the trachea and oesophagus. Giddiness may be induced by similar interfer- ence with circulation, through the large vessels of the neck going to and Coming from the brain. In fibrous goitre the stroma of the organ in- creases more markedly than does glandular tissue, though the pathological alteration is similar in other respects to the simple hypertrophy just described. The thyroid enlargement may be soft and vascular if the growth is rapid, or hard and dense if the change is more chronic in its °ourse. The fibrous form very often affects but one lobe. Its displacing 550 R E SPI R A TO R Y O R. G. A. N. S. pressure is very likely, therefore, to cause lateral deflection of the trachea and oesophagus. As the thyroid gland lies below the deep fascia, any enlargement gives rise to injurious pressure upon the other organs of the neck, as has been indicated above. Such pressure is more apparent when caused by a hard, rapidly growing fibrous goitre than when the change is one of the other varieties of bronchocele. Flattening the calibre of the trachea or interference with the normal movements of the tracheal rings during respiration may cause a tendency to dyspnoea. The ana- tomical attachment of the isthmus of the thyroid body to the trachea causes the gland to rise and fall during swallowing. This furnishes a test in the diagnosis between thyroid enlargement and other cervical tumors. The rise and fall of the mass during deglutition of a little water or food indicate at once the thyroid nature of the growth, since enlargement of the lymphatic glands in the cervical region or other tumors of the neck would in most cases not be affected by tracheal movements. One or more of the acini of the gland may be converted into a cyst or cysts, filled with colloid, serous, or bloody fluid, and constitute the cystic variety of goitre. While the wall of such cysts may be very vascular it may also at times become calcified. In extreme cases the whole thyroid body may be converted into a series of cysts. Goitre is endemic in certain regions of the world, especially in some parts of England and in the Tyrol, and is there often associated with a peculiar deterioration of the brain called cre- tinism. This has been attributed to the atrophy of the gland which accompanies such thyroid tumors. The different varieties of goitre found in these persons attain at times enormous bulk. TREATMENT.—The treatment of goitre differs with the variety of the growth. The treatment of exophthalmic goitre belongs to the domain of medi- cine, and consists in the administration of iron, digitalis, and similar remedies. The treatment of congestive growth is not unlike that of exophthalmic goitre, and consists in the use of digitalis and tonics internally, and counter-irritation by means of tincture of iodine, red iodide of mercury ointment, and similar preparations externally. Ergot, ammonium chlo- ride, and potassium iodide have been advocated in this form of goitre, and are probably of value if given in large doses. In fibrous goitre the remedies recommended for congestive and exoph- thalmic goitre may be applied. The benefit obtained, however, is not so evident in this form of bronchocele. When the growth is large and causes pain and other symptoms of pressure, the surgeon should make a cut through the deep cervical fascia, which will permit the tumor to bulge forward, thereby relieving pressure on the important structures beneath it. The incision may be open or subcutaneous, according to circum; stances. When this procedure is not effectual, the isthmus of the thyroid gland may be divided in the middle line after two strong ligatures have been applied at each side of the proposed incision to prevent hemorrhage. The repeated injection of alcohol or tincture of iodine, in ten minim doses directly into the fibrous tumor by means of a hypodermic syringe, may diminish the bulk by causing interstitial absorption. Cystic goitre. should be subjected to evacuation by puncturing with a trocar an canula, and subsequently to injections of tincture of iodine, tincture of the chloride of iron, or a solution of carbolic acid, if the simple evacuating puncture is followed by reaccumulation of fluid. Care must be taken before injecting these irritants to see whether blood escapes from the B. R O N C H O C E L E O R G O IT R. E. 551 canula after the fluid in the cyst has been allowed to flow out. If blood flows, it is an indication of the possibility of a vein having been punc- tured, and the point of the canula should therefore be withdrawn a little before the injection is made. It is not safe, however, to inject such irritating fluids into rapidly growing tumors, since they are apt to become violently inflamed. Suppuration is sometimes induced by this method of treatment, due to the invasion of pyogenic germs. Spontaneous abscess of the thyroid gland I have found on one occasion. It should be treated by free incision, in order that the pus and the suppurating tissue may be evacuated and removed. Excision of the thyroid gland has been done in cases where the size of the growth and its pressure symptoms have ren- dered the operative risk of such an operation justifiable. According to Horsley, excision of more than one lobe must not be performed, since re- moval of the whole body will lead to myxoedema, and because excision of the isthmus or of one lobe will usually remove the urgent symptoms. C H A P T E R X. X. DISEASES OF THE MOUTH, HARELIP is a term applied to congenital fissure in the upper lip, and may be single or double. The fissure, however, is always a little to one side of the middle line, in a position corresponding with the suture be- tween the inter-maxillary bone and the upper jaw of the corresponding side. When harelip is double, a small portion of the lip lies between the fissures. This central lobule may be very poorly developed; in fact, it may be scarcely more than indicated, thus giving a double harelip the appearance of a single cleft in the median line. The inter-maxillary bone, which carries the incisor teeth, may be separated from the upper maxil- lary bone of the same side by a cleft which corresponds with the cleft in the lip. This is one of the forms of cleft palate. Cleft of the palate is a congenital defect, corresponding in character with harelip, occupying the hard or soft parts of the palate, or both. All of these conditions are due to FIG. 362. defect in coalescence some time # - about the ninth week of foetal life. When the alveolus is cleft and the intermaxillary bone is separated from the other portions of the jaw by such congenital de- fect, the harelip is often compli- cated by protrusion forward of the y FIG. 363. ~ .. '', * lauri º 2-—“S Ž. Single and double harelip. Diagram of incision in operation for (TREves) harelip. incisor and inter-maxillary structures, which thus extend forward below and in front of the nose as a sort of snout. The nostril on the side cor- responding with the harelip is usually broadened and flattened, by reason of the ala being carried outward. Harelip, if at all extensive, prevents the infant from sucking well. This circumstance, as well as because it is difficult for the child's lips to be kept at rest after it has learned to speak, renders it proper to operate when the child is between six weeks and three months of age, provided, of course, that the general health is good. º The plastic operation for harelip consists in separating the upper lip H A R E I, I P. 553 from the gum ; in paring the edges of the fissure, and in bringing them together with pin sutures in such a way as to leave no defect in the vermilion border of the lip. Union by first intention is usually obtained, if the operation is well done and the parts so arranged that there is no tension upon the sutures. The child may be held in the nurse's lap with his head placed between the two knees of the sitting surgeon, or it may be placed upon an operating table. Ether is usually given. Compres- sion forceps may be used upon the upper lip near the corners of the mouth to prevent bleeding from the coronary arteries. A straight, nar- row knife is then used to transfix the tissues on each side of the cleft and to pare away the borders beginning high up in the nostrils at the angle of the fissure. Sufficient tissue must be removed to make a wide raw surface on both edges of the cleft, so that when the lip is brought together there will be a wide surface of contact to cause union. The strip cut off may be entirely removed or a portion may be retained at the lower part in order to make the free margin of the lip bulge a little when the sutures are placed. It is often well to carry the lower end of the incision a little away from the cleft and then turn the knife toward the middle line so as to leave a tag of tissue covered with mucous membrane. The accompanying diagram (Fig. 363) shows this incision, which is made in order that the parts which are brought together may pout a little, and prevent the occurrence of a slight notch in the edge of the reconstructed lip. If this incision is not adopted an incision concave toward the cleft is a good One, because when the concave edges are brought together in a straight line a similar pouting on the margin of the lips is accomplished. A steel pin is then carried through the two portions of the lip and across the gap just beneath the wing of the nose. The flattened condition of the nostril is thus corrected by the same pin which brings the upper part of the gap in the lip together. A second pin is introduced about the middle cleft, care being taken to pass it between the mucous membrane and the coronary artery, in order that the pressure made shall arrest bleeding. The forceps previously applied to prevent bleeding are now removed. Catgut or silk sutures are then carried around the ends of each one of these pins to bring the parts in apposition. A few fine catgut or silk sutures are used along the margin of the lip and upon the internal surface, in order to bring the mucous membrane into accurate apposition. It is very important that the mucous membrane and the skin should be accurately matched at the muco-cutaneous border as deformity is some- times produced by having the mucous membrane run up higher on one side of the repaired cleft than upon the other. This is a very unsightly deformity after union has taken place. ... The wound is dressed with iodoform and collodion, and the child is #d either at the breast or with a spoon. The pins are taken out upon the third day, although the ligatures are allowed to adhere to the incision, in order to assist in supporting it for a few days longer. The sutures in the lºucous membrane may be allowed to remain until the fourth or fifth day. The operation for double harelip is the same. Both clefts are pared and 99"rected at once, pins being passed through the flattened edges of the lip and through the central lobule if it be large enough to be of any ser- X* in filling the gap. The edges of this central lobule are, of course, freshened; but if it is very short it may be necessary to preserve the Pºngs from the lateral margins of the cleft and to use them in filling up º j below the central portion of the lip when the final sutures are pplied. - 554 D IS E A S E S O H' T H E M O U T H . In case of absence of the nasal columella as a complication it may be wise to turm up the central process of the lip to reconstruct the deficiency in the nose. If the inter-maxillary bone or its alveolar portion protrudes it may be cut away with bone forceps or bent up into place after fractur. ing its attachments. The vomer, which is sometimes hypertrophied when this protrusion is present, may be retrenched by excision of a V-shaped por. tion behind the inter-maxillary bone. No attempt is made to correct the cleft in the alveolar process, since the defect is covered by the lip and can be remedied, when the child has reached adult life, by artificial dentures. If union by first intention fails in attempts at curing harelip, it may be necessary to do a secondary operation, in order to get a perfect result. CLEFT PALATE. Cleft palate, which is similar in its origin to harelip, is much more diffi- cult to repair by plastic procedures. The cleft is in the middle line except when it is in the anterior portion of the hard palate, when it may be a little to one side of the middle line. The fissure may sometimes be double in front with the incisive bone lying between the two clefts. It is more common, however, to have only the soft parts of the palate fissured. The operation for the repair of the soft palate is called staphylorrhaphy, while a similar operation on the hard palate is called uranoplasty. Cleft palate interferes with deglutition and speech, because it is usually impossible for the patient to close the pos- terior nares, which is essential in proper deglutition and speaking. In infants deglutition is often very difficult and the milk is regurgitated into the nasal *- cavities. These conditions are, of course, greater Fissure of soft, and hard when the cleft is a large one or involves both the palate. (SMITH.) hard and soft palates. In the milder form the child, when beginning to talk, should be especially trained in articulation; as by special development of the muscles he may be able to overcome this defect in speech to a great extent. In more severe cases benefit may be derived by applying to an oral surgeon for the adaptation of an artificial palate. Artificial palates, however, are not sufficiently satisfactory to prevent the adoption by many of operative proceedings in great palatal defects. r The operation for cleft palate to be most successful should be done before the child has fully acquired the art of speech. About the third year is the proper time. If the patient is young he should be etherized, but in adults the use of cocaine will render general anaesthesia unneces. sary. The mouth must be held open by means of a gag. The edges ºf the cleft, when the fissure involves only the soft palate, should be carefully pared, from the angle of the fissure backward to the free margin of the velum, after which the two sides of the velum must be brought together by silk or wire sutures passed by means of a curved needle. º Before passing the sutures in the operation of staphylorrhaphy it is well, in cases where the cleft is large, to cut the two elevator and tensor muş cles of the palate, in order to diminish tension on the soft palate, which is about to be drawn together. This is done by passing a tenotome through the soft palate on the inner side of the hamular process, which can be felt FIG. 364. E PIT H E L I O M A OF T H E LI P. 555 at the outer side of the roof of the mouth, and carrying the edge of the tenotome upward and then downward, thus dividing the muscles. The flaccid and immobile condition produced by the division of these muscles will prove that the division has been successful. The sutures are then passed and tied. . During the after-treatment the patient should be pre- vented from coughing or talking, and fed on liquid food. In the operation of uranoplasty, or closure of cleft in the bony palate, two strips of mucous membrane with the underlying periosteum are sepa- rated from the hard palate on each side of the fissure and drawn toward the middle line, where they are held together by sutures. The incisions for raising the muco-periosteal flaps are made antero-posteriorly near the alveolar process, and along the edge of the cleft. The flaps are then dis- sected up, but are left attached at both ends. The middle portions of the strips are then pushed laterally toward the middle line and sutured, while the raw surfaces left by their removal heal by granulation. The soft palate is repaired as described above, Some surgeons prefer to cut entirely through the hard palate with a chisel and displace the detached portions of bone toward the median line. If preferred by the operator, the patient's head may be allowed, in operations on the palate, to hang over the end of the table, so that the roof of the mouth is below the operator. The blood then runs into the nose and does not obscure the field of work. Operations for the relief of cleft palate, even when extensive, are often quite successful, but at best they make a rather poor substitute for the normal roof of a mouth. Subsequent to their use, careful training of the child in articulation is very important. EPITHELIOMA OF THE LIP. Herpes, ulcerations of the non-malignant kind, and inflammatory fis- sures or cracks in the lip belong to medicine. Epithelioma, however, is $0 common an affection, especially among men, and in the lower lip, that it deserves special attention at this point. It is possible that smoking a clay pipe, and similar long-continued irritations, may be factors in the Causation of this malignant disease. The upper lip is occasionally the seat of epithelioma. At first the variation from health in the tissues is $0 slight that it is overlooked; but after a time the patient notices a small hard module, which subsequently ulcerates, or an intractable ulcer or fis- Sure appears upon the lip and refuses to heal. Induration about the base of the lesion steadily and gradually increases in size, and a little later involvement of the submaxillary and cervical glands gives evidence that the disease is a malignant one. Epithelioma of the lip does not cause much pain; when ulcerated a thin discharge is secreted. Death may take place from exhaustion or hemorrhage, or from secondary involve- ment of the internal organs. Ppithelioma and lupus of the lip are sometimes similar in appearance, but the latter does not involve the cervical and submaxillary glands. The diagnosis between epithelioma and chancre of the lip is exceedingly *Portant. Chancre occurs at any age, while epithelioma is more common after the age of forty years. Chancré begins as an ulcer, as a rule, whereas *Pithelioma ordinarily begins as a nodule. In the syphilitic affection the ymphatic glands are involved earlier; and the sore, even when it attains * maximum, is not so extensive in its progress as the cancerous affection; 556 D IS E A SES OF T H E M O U T EI. and in addition there may be some syphilitic fever. Secondary eruptions may also appear, to assist in the diagnosis; and most important of all, the syphilitic sore promptly yields to mercurial treatment. Epithelioma of the lip, before secondary involvement of the internal organs has occurred, is usually exhibited in the lymphatic glands under and behind the lower jaw. The original site of disease and the involved glands slowly ulcerate, and destruction of the tissues about the mouth and throat is finally very extensive. Labial epithelioma should be treated by prompt and radical operation, except when the disease has extended as indicated; then pro- longation of the patient's life by anodynes and supporting measures is all that can be done. Excision of epithelioma of the lip is accomplished by the removal of a V-shaped portion of tissue with the base of the wedge at . the margin of the lip. During the operation the lip is held everted by an assistant's fingers, which also press upon the coronary arteries at each side of the proposed incision. The excision should be done soon enough to insure entire removal of the malignant mass. The divided lip must then be brought together by one or two pin sutures, so passed as to make pressure upon the coronary arteries and prevent bleeding. Along the edge and inner surface of the lip the mucous membrane should be united by fine catgut sutures. The wound should then be dressed with a little antiseptic absorbent cotton, held in place by iodoform and collodion painted upon it. It may be necessary in more extensive infiltration to cut a larger portion of the lip away and to construct a new lip from the tissues covering the chin by slipping up one or too large cutaneous flaps. Excision of a portion of the jaw is required if the disease has in- volved the bone tissue. Enlarged glands under the jaw and in the neck should be removed at the same operation. The prognosis after excision of epithelioma of the lip is usually quite good, if the portion attacked permits of free removal. If the growth returns, it should be removed a second time. TUMORS OF THE MOUTH. Tumors of various kinds may be found upon the buccal surface of the cheeks and in the floor of the mouth. The most common form, perhaps, is the cystic tumor, occurring beneath the tongue and usually upon one side of the fraenum, to which the term ranula is usually ap- plied. Ranulae contain a more or less transparent, gelatinous fluid, re- sembling saliva. They are sometimes dilated ducts of the submaxillary or sublingual glands, and at other times occur as dilatations of the ducts of the mucous glands in the floor of the mouth. True hydatid cysts have been found here, and the bursa above the hyoid bone has been known to become enlarged, and resemble ranula. These cystic tumors are soft, elastic swellings, which gradually increase in size. They sometimes be: come so large as to push out the tissue of the neck below the jaw and make a distinct bulging upon the exterior of the throat. Adipocere and rice-like bodies have at times been found in ranulae. e The treatment of these non-malignant growths consists in puncturing the sac so that evacuation of fluid takes place, and then setting WP sufficient irritation of the lining membrane to cause obliteration of the cavity. This last object may be obtained by scraping the interior of the sac with the trocar and canula with which its fluid contents have been withdrawn, or by laying open the sac with a knife and mopping T U M O R S OF T H E J A W. 557 out its interior with chloride of zinc or carbolic-acid solution. Some surgeons prefer to operate by making, an opening in the cyst wall, and keeping the orifice patulous by turning a portion of the wall inward and stitching it with its internal surface toward the interior of the sac. A seton may be passed through the sac, so as to evacuate its contents and give rise to plastic adhesion of its walls. , Large cysts projecting externally may require to be attacked by incision in the neck. After evacuation, the cavity of the cyst is then stuffed with antiseptic gauze. It is occasionally possible to dissect out the cyst by means of external incision. ALVEOLAR ABSCESS. Abscesses of the alveolar process may be superficial, when they are called gum-boils, or deep, when the pus originates in the tissues around the root of a tooth. Abscesses occurring in the tooth sockets are usually due to disease of the teeth, as, indeed, is usually the case in superficial abscess. The pus in superficial abscess is not confined by bony tissue, as in the deeper form, and is, therefore, the seat of but moderate pain. In those cases in which the pus is confined in the dense walls of the tooth sockets the pain is excruciating, and is only relieved when the pus is evacuated either spontaneously or by drilling the bone or the tooth. Re- moval of a filling which has been previously placed in a carious cavity in the crown of the tooth by the dentist may afford exit to the confined pus. Escape of the pus gives instant relief from pain. When the pus does not thus find its way through the bone in which the tooth is lodged, it may finally be evacuated alongside of the tooth after it has reached the upper edge of the socket. Occasionally, the suppurative process gives rise to a fistulous opening in the cheek or in the roof of the mouth, and may even cause destruction of the palate bone and penetrate into the nasal cavity. The treatment of alveolar abscess consists in the use of leeches locally to the gum ; painting the gum with tincture of aconite root ; the applica- tion of heat and moisture, which is best accomplished by the use of a hot fig or raisin applied to the gum; incision of the gum, and, in deep abscesses, boring of the bone or tooth, in order to permit the escape of pus. In many instances the tooth should be seen by a competent dentist, since removal of the filling and treatment of the abscess cavity through the tooth may hasten cure and preserve the structure. Acute subperiosteal abscess may occur in connection with alveolar inflammation, and lead to more or less extensive destruction of the bone by necrosis. Early and thorough incision is the proper treatment. TUMoRS OF THE JAW. Growths involving the alveolar process of the jaw, but not the bone Very extensively, have long been given the name epulis. This term, however, should be discarded, since it has no strict definition, and many cases of so-called epulis would be better understood and more effectively treated if called tumors of the jaw and described by their proper adjec- "We as fibromatous, sarcomatous, and carcinomatous. The common growth to which the term epulis is applied is a fibrous mass, usually if not always arising from the periosteum or bone, and presenting itself as * Smooth, firm, elastic growth alongside of or between the teeth. It may 558 D IS E A S E S OF TH E M O U T H . become ulcerated. These fibromas are more common in the lower than in the upper jaw, and they appear to be due to the irritation caused by decayed teeth. Such fibromas should be removed by operation within the mouth in order that the scar may not appear upon the cheek. They are ordinarily easily cut away with a strong knife or gouge, though it may be necessary to extract one or more teeth in order to make the extirpation complete. They are not apt to return. - Malignant tumors of the jaw, whether occupying the alveolus, and therefore being a form of epulis, or arising from the central portion of the jaw-bone and gradually extending to the surface, should be removed by very free incision through the soft tissue and bone. Such malignant growths require total or partial excision of the jaw, the amount of bone, removed depending upon the time at which the operation is done. In Some instances it is sufficient to cut away the upper margin of the lower jaw without making the section complete. Similar tumors affecting the upper jaw may require its complete or partial resection. Non-malignant growths of the jaws, as has been stated, may require only partial excision of the bone, or possibly may be enucleated without taking away much of the bone tissue. Malignant disease, however, whether it involve the upper or lower jaw, should be removed by very free incisions and by enucleating any of the lymphatic glands which may be secondarily involved. Where it is impossible to get beyond the recog. nized limits of the disease, operation may be unjustifiable, although some instances seem to indicate that removal of the major portion of the growth by means of a knife and the application of chloride of zinc solu- tion to the surface left may be followed by prolongation of life. Cystic, as well as solid, growths may develop within the antrum or cavity of the upper jaw bone. Such tumors occasion great deformity as the growth pushes the walls of the antrum into the neighboring fossae, or outward upon the face. By this means the eyeball may be protruded because the floor of the orbit is raised; the nasal chamber may be occluded by the growth ; the hard and soft palate may be pushed down- ward, and the face may be deformed by protrusion of the cheek. Diffi- culty in breathing and difficulty in swallowing may result from such antral growths. Cerebral complications may also occur, as well as blind- ness and profuse nasal hemorrhage. Solid growths in the antrum are to be distinguished from cystic growths by their firmness, and by the fact that in the latter case fluid is evacuated when the antrum is tapped from within the mouth above the canine tooth. Rapidity of growth occurring in persons beyond the middle age and involvement of the submaxillary and other lymphatic glands suggests that the tumor is malignant rather than benign. This diagnosis is confirmed when rapid infiltration occurs outside the bony walls of the antrum, because it indicates that the malig- nant tumor has involved the bony walls and spread to the soft tissues, Cystic tumors within the antrum may owe their origin to the abnormal development of a tooth within the antral cavity. Such dentigerous cysts are not uncommon. NECROSIS OF THE JAw. Necrosis of the jaw is not uncommon in those exposed to the fumes of phosphorous acid in the manufacture of matches. It is probable that this disease, called phosphorus necrosis, occurs only when the patient, is the subject of diseased teeth. The necrotic portion of bone should be IN FL A. M M ATION OF T H E TO N G U E. 559 removed by operation within the mouth so as to avoid a scar. This should not be done ordinarily until the sequestrum has become detached, because it is desirable to retain the integrity of the arch of the jaw-bone which in earlier attempts at removal may be fractured. Where the sequestrum is very large it may be necessary to make an external incision. The application of artificial dentures to the defective bone after the removal of such large portions may give a useful lower jaw. Actinomycosis is a disease due to a parasitic fungus which has been known to attack the jaws and to be the cause of necrosis. Necrosis also occurs secondarily to some of the essential fevers, and as a symptom of tuberculosis, syphilis, injuries, diseased teeth, and excessive mercurializa- tion. Ankylosis and articular disease of the temporo-maxillary joint have been discussed elsewhere. DISEASES OF THE TONGUE. When the fraenum of the tongue is abnormally short, preventing the protrusion of the tip beyond the teeth, and limiting its movements within the mouth, tongue-tie is said to be present. This condition sometimes prevents a young child from suckling, and in older children interferes with perfect articulation. Tongue-tie, however, does not prevent speech and make a child dumb, as is sometimes supposed by the laity. When tongue-tie exists to any marked extent it should be remedied by clipping the edge of the franum with the scissors. The incision should be about one-eighth of an inch deep. The surgeon's finger can then tear the tissue and establish lingual movements. The ranine arteries lie in the fraenum close to the lower surface of the tongue. Division of these vessels is avoided by keeping the point of the scissors turned downward. Reunion of the cut portions of the fraenum should be prevented by sepa- rating them daily with a probe or with the finger. The edges of the slight wound will have cicatrized in four or five days. INFLAMMATION OF THE TONGUE. Glossitis, or inflammation of the tongue, may be acute or chronic, simple or specific. Simple or superficial inflammation of the mucous membrane of the tongue occurs in connection with stomatitis or inflam- mation of the mouth. Stomatitis is applied to inflammation of the mucous membrane lining the cheeks, lips, and other oral structures. It may arise from digestive disorders, the administration of iodine, mercury, and other drugs, and as a lesion of secondary syphilis. Mucous patches and erythema are the pathological conditions of the mouth most prone to follow syphilis. It must be remembered that chancre itself may be fouud in the mouth. Syphilis may be exhibited by mucous patches or gummy deposits or ulceration in the tongue. General parenchymatous inflam- mation of the body of the tongue of an acute kind occasionally occurs, and is quite a serious condition. It may be due to wounds or to insect bites, or it may occur without apparent cause. The tongue is swollen and red and shows a smooth surface. Pain, which is great, is perhaps increased during efforts at taking food. The flow of the saliva is abun- 'ant and the interference with respiration may be marked. The condi- tion is occasionally followed by sloughing. - Syphilitic glossitis requires constitutional treatment and local stimu- 560 DISE A SES OF THE MOUTH. lating applications. Acute parenchymatous glossitis should be treated by leeches applied under the jaw externally and the use of cracked ice in the mouth, while the patient is nourished with liquid food. If these means do not relieve the swelling and the inflammatory symptoms, incision should be made in the tongue to the depth of one-half inch along each side of the middle line, beginning well back upon the dorsum of the tongue, and extending nearly but not quite to the tip. The relief from tension and swelling given by this incision will usually be immediate. Antiseptic mouth-washes should be freely used thereafter. Injuries to the tongue and the impaction of foreign bodies in the organ give rise at times to acute or chronic suppurative inflammation or abscess of the tongue. If the puriform fluid lies deeply in the organ the chronic abscess may be surrounded with infiltrated tissue sufficiently hard to cause resemblance to a tumor imbedded in the lingual muscles. Such abscesses of the tongue are treated by incision and the removal of more or less inspissated puriform fluid with the curette. Chronic abscess is probably tubercular in its etiology. In addition to these forms of glossitis there occurs a chronic superficial inflammation to which the names leucoma, psoriasis, and ichthyosis have been applied. EPITHELIOMA OF THE TONGUE. Various benign and malignant tumors may occur in the tongue, but the most common of all is epithelioma, which is a disease with distressing symptoms. It is more frequent in man than in woman, is a disease of rather advanced life, and apparently may at times arise secondarily to superficial glossitis. Smoking, the immoderate use of spirituous drinks and of condiments, irritation from jagged teeth, as well as syphilis, have been suggested as possible predisposing causes. Epithelioma of the tongue appears usually on one side of the middle line toward the root of the organ. Superficial ulceration with indurated base and edges is an early evidence of the disease. The pain is at first slight, but the discomfort increases during eating and other movements, until it becomes very great. The saliva flows more freely and the breath becomes fetid. The floor of the mouth and fauces become involved, as do also the lymphatic glands below the angle of the jaw. Slight or pro- fuse hemorrhage may occur. Impaired nutrition, due to the difficulty in feeding and the swallowing of foul secretions, is soon evident. If one of the lingual arteries is opened by ulceration, fatal hemorrhage probably supervenes, while death may also occur from Septic pneumonia, due to inhalations of the Secretions from the malignant growth. & The diagnosis between epithelioma of the tongue and ulcerative syphi. litic gumma is at times difficult, but the doubt can easily be cleared up by the use of mercury and potassium iodide in full doses. Specific disease under this treatment will soon show evidence of improvement. The only effective treatment for epithelioma of the tongue is early and complete removal of the whole tongue and of any lymphatic glands below the jaw, which may be involved, "Where the disease has progressed tº the involvement of the floor of the mouth before the surgeon is consulted it may be doubtful whether operation is justifiable. In such a case liga. tion of both lingual arteries may possibly retard the development of the growth, and excision of a portion of the lingual nerve on the side affected may relieve pain. This nerve can be felt in the mouth lying underneath E PIT H E L IO M A OF THE TO N G U E. 561 the mucous membrane at the angle of the lower jaw, vertically below the second lower molar tooth. An incision through the mucous membrane will enable the operator to take up the nerve by means of a hook and to excise a portion of it. This neurectomy lessens pain and diminishes the uncomfortable flow of the saliva. The pain which makes lingual move- ments distressing may also be mitigated by painting the diseased tissue with cocaine, about forty grains to the ounce. The patient may require feeding by enemas, or by having a tube passed through the nostril into the pharynx. CEsophagotomy may be available for feeding in cases where the fauces are obstructed by the growth. It has been proposed to perform tracheotomy in order to prevent inhala- tion of the foul discharges which give rise to septic pneumonia. This seems scarcely necessary, since the free use of antiseptics with frequent powdering of the cancer with iodoform will preserve a fairly clean con- dition of the ulcer. The tongue can be entirely removed by dragging it forward while the mouth is held open by a gag. A strong string passed through the organ at its tip will give the operator control of it, and enable him to pull it well out of the mouth, and by successive manipulations with the scissors the organ can be cut away without difficulty, and the spurting vessels tied as they are divided. It is well to have a ligature of silk passed through the stump and brought out of the mouth after the removal of the organ, in order that the patient may not be suffocated by the base of the tongue falling backward into the pharynx. This danger does not exist after twenty-four hours have elapsed. It is often advantageous to split the tongue in the middle line antero- posteriorly before attempting its complete removal with the scissors. So, also, in cases where the écraseur is applied to extirpate the organ, it is Well to operate upon the two halves successively. Operation with the scissors, however, seems more surgical and accurate than that by means of the écraseur, because the direction and extent of the incision can be better regulated. The mouth should be well packed, after drying of the stump, with iodoform gauze, which should be pushed into every irregu- larity of the mouth, and retained several days until cicatrization of all the surfaces has been accomplished. The patient should not be allowed to talk or take food by the mouth for a week. Alimentation can be kept up by the rectum. If this radical operation is done early in the course of the disease, a considerable prolongation of life is usually secured. It is, however, bad . to attempt partial removal of the organ in cases of malignant 1Séa Se. Access to the tongue, in order to accomplish its complete removal, may be obtained by making a horseshoe incision in the throat under the lower JºW, going through the floor of the mouth, or by making a straight cut from the centre of the lip to the chin, accompanied by division of the jaw bone With a saw at the symphysis. Ordinarily, however, the method first described—namely, that of dragging the tongue out of the mouth—is efficacious. Subsequent to the removal of the tongue, the speech is not so imperfect as Would be expected. 36 562 I) IS E A SES OF TH E M O U T H . DISEASES OF THE TONSILs. Tomsillitis, or quinsy, may go on to suppuration, and require incision for the evacuation of pus. A sharp-pointed bistoury should be carried through the swollen gland and the surrounding tissue until the pus col- lection is entered. Usually the abscess is localized at the upper point of the tonsil, where it joins the soft palate. The point of the knife must never be carried outward, since the internal carotid artery lies just exter- nal to the gland. Detergent washes should be used after the operation. Relief is immediate. A solution of sodium bicarbonate has been highly lauded as an application in quinsy prior to the stage of suppuration. Syphilitic lesions and malignant tumors are at times found in the tonsil glands. Hypertrophy of the tonsils is a chronic condition, probably inflamma- tory in its character, which is often seen in children. These enlarged tonsils are frequently associated with recurrent attacks of inflammation of the throat, and it is possible that they may have some relation to local tubercular infection. The increase in size may be so great that the enlarged glands extend to or beyond the middle line of the fauces, so that the opposite growths come in contact and result in mutual pressure. |Ulceration of the masses may be thus induced. The disease causes ob- struction to breathing and swallowing, and compels the child to keep its mouth open almost constantly, and to snore during sleep. When the enlarged glands are attacked with acute inflammation, the difficulty in breathing may approach Suffocation. FIG. 365. º: | ) -..….: '. -->
