Much light has, of course, been thrown on the subject, and many use- ful practical inferences drawn from a more accurate knowledge of the structure: still great variety exists in the descriptions of different authors, and, consequently, much difficulty is thrown in the way of the Student anxious to make himself master of the subject. Many parts have a variety of names affixed to them, and many again are divided and subdivided, each of their separate parts receiving distinct appellations. no retro of em not 718225 ond How zi di 7d barabta vet Several years ago, far from being satisfied with the demon- stration of the parts concerned in Femoral Hernia, as given by the most eminent Anatomists, and finding, on more accurate investigation made on a number of subjects, that their descrip- tions did not correspond with the structure of the parts, I continued to inquire into the matter, and last year demonstrated to my Class of Anatomy the views which I had been led to take of the formation of the Crural Arch, and parts connected with it. I then began to perceive, from the simplicity of the de- B 6 monstration, that my pupils understood exactly the appearance, connexion, and uses of parts, which before they had heard enough about, but could never understand. It is well known, that the anatomy of this situation is con- sidered by Students one of the most difficult; and that very few can, without much labour, form any just idea of the struc- ture. I therefore conceive, that if I can throw any light on the subject, or smooth at all the difficulties of attaining a true and accurate knowledge of it, I shall do a service, at least, to the younger members of the profession. If so, I shall completely attain my object. In order to make the description more easily understood, and that no ambiguity with regard to terms may exist, I have added three plates of the anatomy from very beautiful and accurate sketches, for which I am indebted to my friend, Staff Surgeon SCHETKY, who unites to the freedom of a master in the use of the pencil, the truth and accuracy of a skilful anatomist. The drawings were made from my own dis- sections for the purpose, and not before a very great number of similar ones had been examined. rises user bas modes in gaivies after oturages rieds It must appear quite unnecessary for me to enter on a de- scription of the abdominal muscles; these are well known, and their situation and connexions accurately enough laid down in the common manuals of anatomy. It is chiefly that part known under the name of the ligament of Poupart that I have to notice. This part, though named a ligament, and cer- tainly composed partly of parallel fibres, running from the an- terior superior spinous process of the ilium, to the tuberosity of the pubis, cannot be separated from the tendon of the external oblique muscle of the abdomen, of which it forms the lower MiU 7 boundary. It has been described by all anatomists and sur- geons as reflected upon itself, forming a round thick edge ex- ternally; and internally again presenting a kind of sharp grooved appearance.* It is also said to send a process to be at- tached to the spine or crest of the pubis, forming a lunated edge, generally known under the name of the ligament of Gimbernat. It is this lunated edge that very frequently forms the stricture in Femoral Hernia, and which requires to be divided in the operation. It has been proposed also to di- vide the ligament of Poupart, in order to remove the strangu- lation of this species of rupture; but what effect this would have in relieving it, will immediately be seen by an examination of the anatomical structure. to slow simile asce efs komen of mi notoiberines e rose estamo It is one of my objects, in this paper, to shew that the liga- ment of Gimbernat is totally unconnected with that of Pou- part; that this part, or, what is the same thing, the inferior pillar of the external ring, instead of being turned down from its attachment to the tuberosity of the pubis, to be fixed to its crest, frequently sends fibres, in a curved direction upwards, to strengthen the conjoined tendon of the internal oblique and transversalis. The ligament of Poupart has also been named the Crural Arch; and the different fasciæ, in this situation, have been described by some as attached to its upper or lower * This reflection is but very slight, and that only close to the tuberosity, and is pro- duced by the insertion of the more descending fibres into the straight and parallel ones. + The insertion of the parallel fibres under the descending ones into the tuberosity of the pubis, is named, by some Surgeons, the ligament of Gimbernat; but the whole lunated attachment to the spine of that bone, is, by all writers with whom I am ac- quainted, so denominated. 8 00 edge; by others, as arising from it. It will, however, appear, that the Crural Arch is formed by a union of the fasciæ, un- der the ligament of Poupart; and this we shall proceed to shew. o a 88900 orga brez et hice ople at JI 9008 eggs bevoorg Seteral e quinol gidug ed3 10 or so enigz edi of bedes o In the dissection of the parts in the groin, the first fascia which presents itself, is that strong expansion covering the lower part of the tendon of the external oblique, and extending down along the spermatic chord in the male.* This fascia is described as attached to the edge of Poupart's ligament, and afterwards continued over the fore and upper part of the thigh containing the glands of the groin; and, in this situation, named the loose Cellular Fascia of the thigh. The very name carries a contradiction in the face of it. In the healthy state of the parts, there is, in this situation, nothing but a loose cel- lular substance, containing a quantity of adipose matter, envel- oping the glands. In cases, again, where Hernia has existed for some time, there is formed a very firm and dense covering, then, to be sure, deserving the name of fascia.† The Superficial Sure mi asadit abuse ylineupert *This fascia, in Inguinal Hernia, forms a layer above the tendon of the cremaster. In ventro-inguinal Hernia, it is of course the only proper covering under the common integuments. In a case of this kind, it formed so dense a layer, as at first to be mis- taken for the Hernial Sac, covering a quantity of fat doughy substance, resembling omentum. On examination, this fat was perceived to be deposited on the true Hernial Sac, which was thus rendered three-fourths of an inch thick. corcomb noites + It is from this part being described as a fascia, that the opposers of the new doc- trines, with regard to the anatomy of this situation, draw their arguments, and say, that the cellular substance and fat may be sliced, like a cucumber, into as many layers as the dissector pleases. That some anatomists have carried the rage for the discovery of fascia too far, is no reason why those parts which are distinct, and which evidently alter and modify the appearances of hernial tumors, should be described, as formed by the knife, and not existing in nature. The translator of Scarpa's splendid work on 9 Abdominal Fascia is totally unconnected with this fatty layer on the fore part of the thigh; neither is it attached to Poupart's ligament; but, on the outer or iliac side, it is firmly united to the combined fascia at this part, and forms one continuous expansion with the external layer of the falciform process of the fascia lata of the thigh. On the inner or pubal side, it has a slight union with that part of this fascia which covers the pectineus and adductor longus, and is, as mentioned before,. continued over the spermatic chord, or round ligament. ffy Joniset teom The Fascia Lata of the thigh, at its upper part, has been most accurately described as separating into two portions, thus form- ing an opening for the passage of the vena saphena, and indeed of the blood vessels, nerves, and absorbents, passing out of, or en- tering the abdomen. The inner or pubal portion, that which covers the pectineus and head of the adductor longus, passes under the vessels, over the brim of the pelvis, and forms one continuous expansion with the fascia iliaca. The outer or iliac portion, with its falciform process,* lying on the anterior part of Hernia has made a very bold assertion regarding the fascia of the groin, and has brought in the names of two celebrated anatomists to corroborate his opinions. "They ❝ have repeatedly complained," says he, " that they had less trouble in demonstrating "the natural structure of these parts in the manner of Scarpa, than in manufacturing "new forms with the knife, to explain to their pupils what is meant by these fascia." Notwithstanding the high authority with which this opinion is supported, no doubt can exist in the mind of any person, who will carefully examine the parts for himself, after the method to be described. * This part was first described by the late Mr A. Burns under this name, who also called the edge of what is generally considered as Gimbernat's ligament, the cres- centic portion. These names, as being more accurate, I propose to retain, omitting alto- gether the name of Gimbernat's ligament, as, by different authors, it is attached to very different parts. Some anatomists have confounded the two names of falciform pro- cess and crescentic edge, and used them indiscriminately. This must of course be. guarded against. C 10 the vessels, is divided into two layers. In many subjects this division is quite distinct without much dissection; on all it can easily be demonstrated. Many anatomists describe the falci- form edge as altogether artificial, and, in a great measure, form- ed by the knife of the dissector; and before I completely un- derstood the connexion of these fasciæ, I was, I confess, some- what of this opinion. If the integuments of the abdomen, along with the superficial fascia, be reflected over the thigh, the chance is, that the external layer of the falciform process, which is most distinct, will be dissected off, leaving only its internal layer. This I have often seen happen; and then the question may be put, where is the falciform process? The want of it does not arise from any imperfect formation, but rather from the awk- wardness with which the dissection has been conducted. The attachment of the superficial fascia to the external layer of the fascia lata, ought not to be divided, and then, on re- moving the fat and glands at the upper part of the thigh, the falciform process will easily be brought into view. The falci- form process of the fascia lata is twisted at its inner part, un- der the ligament of Poupart, and this twisted portion is, by Mr Hey, named the femoral ligament. It turns in thus to form the anterior layer* of the crescentic part of the Crural Arch. On removing the superficial abdominal fascia, and the external layer of the falciform process along with it, the internal layer * The division of this part of the Crural Arch into distinct layers, I first observed and demonstrated in 1815, at which time I filled the situation of House Surgeon to the Royal Infirmary in Edinburgh, and in which capacity I embraced eagerly the great opportunities which it afforded of examining both the sound and diseased appearances. I find that Clocquet, a late French writer on Hernia, has noticed the division of what he calls the ligament of Gimbernat into two layers, but still he considers it as a part of the ligament of Poupart, or the reflection of the tendon of the external oblique upon the crest of the pubis. 11 of that process will be found to be continuous with the fascia transversalis. This Fascia Transversalis, first described by Mr Cooper, is ge- nerally considered as attached to the inner edge of Poupart's ligament, along the crest of the ilium, firmly united with the fascia iliaca; and it is this connexion (which is easily seen even to the middle space, between the spinous process of the ilium and tuberosity of the pubis), which prevents the protrusion of the bowels betwixt the ligament of Poupart and the psoas and iliacus muscles. The fascia iliaca, after leaving the mus- cles, passes under the vessels, as said before, to meet with the pubal portion of the fascia lata. A kind of oval space is thus left for the vessels, &c. bounded behind by the bone covered by the fascia, on the inner side by the crescentic portion of the Crural Arch, before by the Crural Arch, and on the outer side by the meeting of the iliac and transversalis fascia. This space is by many Surgeons named the Crural Ring. The fascia transversalis then passes upwards under the muscle of that name, gradually getting thinner as it ascends. Its extent and strength varies in different subjects; but it can at all times be easily de- monstrated, forming an opening for the passage of the sper- matic chord, or round ligament of the uterus, with a superior semilunar edge, and provided with distinct pillars. The inferior pillar, where it joins with the fascia iliaca, and inner layer of the iliac portion of the fascia lata, is by much the strongest, and is composed of distinct fibres running in the direction of those of the ligament of Poupart. I have little doubt that this has by many been considered as the folding in of the lower border of the external oblique upon itself. The internal or superior pillar is chiefly formed of the tendon of the transversalis, 12 which passes down to be inserted into the crest of the pubis. From the opening for the passage of the chord through the fascia transversalis, a production of this mem- brane is continued under the cremaster muscle, forming that layer in Inguinal Hernia which is next the Sac. Thus the opening is not truly a ring, but merely the mouth of a funnel; and it is only after this covering of the chord is re- moved, that any thing like a defined edge is presented. This, as far as I know, was first described by Clocquet, and is very dis- tinctly expressed in Plate II. That the fascia are unconnect- ed with Poupart's ligament, and that they are all conjoined under it, can easily be demonstrated. If, after dissecting off the superficial abdominal fascia from the external oblique, leav- ing it attached to the falciform process, and raising the exter- nal and internal oblique muscles, so as to expose the lower border of the transversalis, and the passage of the chord through the fascia transversalis, - an incision be cautiously made through the tendon of the external oblique, and through its inferior border, or Poupart's ligament, at its middle part, it will be found very easy to separate the fibres, merely with the forceps, towards the attachments of the ligament to the ilium and pubis. This may be done without any laceration of the fibres; and thus the true connexion of the fascia underneath, totally un- connected with this ligament, will be immediately perceived. It will then also be found, that some of the fibres of Poupart's ligament, are, after being attached to the tuberosity of the pu- bis, reflected under the chord upon that part of the tendon of the internal oblique and transversalis, which is opposite the external ring; thus forming a security against the occurrence of ventro-inguinal Hernia. Not a single fibre goes to be in-. serted into the crest of the pubis, which is situated at least: 13 half an inch above the attachment of this ligament to the tu- berosity of that bone. It thus appears, that the lower border of the external oblique lies in the angle of union of the super- ficial fascia with the fascia lata and transversalis, and is con- nected to them only by cellular substance. Ditor od 9radt década leurs ad Although the ligament of Poupart is removed, still the Cru- ral Arch remains not much weakened. That part of the arch attached to the spine of the pubis, which I have all along named its crescentic part, is also left; and, on examination, will be found to be divided into three layers, between which the han- dle of the knife can be introduced down to the bone, and felt by the finger passed under the arch. The anterior or external layer of this ligament, I said before, will be found to be formed by the twisting in of the falciform process; the internal layer, again, by the dipping down and attachment of that part of the fascia transversalis, which forms the inferior pillar of the inter- nal ring, to the ligamentous substance covering the bone. The middle layer is formed by the attachment of the lower part of the combined tendon of the internal oblique and transversalis, to the crest of the pubis and the descending fibres, strengthened by a strong cross slip from the attach- ment of the rectus abdominis of the opposite side. The in- ner layer, formed by the fascia transversalis, is also thus ren- dered stronger. When the external and internal layer of the crescentic part of the arch are removed, the internal layer will be observed to form an acute angle with the ligament of Pou- part, and the lunated appearance is produced by the filling up of the angle by the junction of the other two layers. emos deuord mited qand alduch edi o BUCH We may, in short, consider the fascia lata, at its upper part, D 14 as divided into two portions; the one the pubal portion covering the heads of the adductors of the thigh, and becoming continu- ous with the mesial part of the fascia iliaca; the other, the iliac portion, covering the vessels. The cellular substance, connecting these two portions with the vessels, on the anterior and posterior part, forms what has been named the crural sheath, or sheath of the vessels.* The iliac portion, forming the falciform pro- cess, is again divided into two layers; the one passing anterior- ly to the abdominal muscles, and named the superficial abdom- inal fascia; the other, again, lining their inner surface, and pass- ing betwixt the transversalis muscle and peritoneum, forming the fascia transversalis. The lower part of the abdominal mus- cles and Poupart's ligament thus lie in the angle of splitting, or union of all these fasciæ, and the Crural Arch is formed by this junction. ginou 643 rd a 28 From this view of the parts, it will immediately be under- stood how the Crural Arch can be relaxed, and the reduction of Femoral Hernia, either before or during the operation, fa- COD red Deed benid benidmoo od do veten ed Lo * The vessels in all parts of the body receive a strong sheath of cellular substance, which binds them together; but here they have been described as having two sheaths: this, however, is not the case. It has been disputed, whether or not the tumor of Crural Hernia passes in the sheath of the vessels, by which is meant that cellular con- nexion, anteriorly with the Crural Arch, posteriorly with the pubis and pubal portion of the fascia lata; as no force could possibly cause the insinuation of the sac into the true sheath. The Crural Hernia passes, on the inner side of the vein, generally through some of the foramina in that tough cellular substance, filling up that space which serves for the passage of the lymphatics. Part of the tumor is sometimes forced through some of the openings in the iliac portion of the fascia lata, through which the lymphatics perforate, and the indentations caused by the elongation of the membra- nous slips, which often cross these foramina, produce the appearance of the double Fe moral Hernia. Toda a vem sy 100 15 cilitated, by the bending and rotation of the thigh inwards, or the carrying of the one limb across the other. This relaxation of the arch will account for the frequent occurrence of Femoral Hernia, in people falling under great weights; in which case the knees are commonly forced together. The ligament of Poupart cannot possibly be at all affected by the motions of the inferior extremity, as extending betwixt two immoveable points of bone. Whereas the tension of the Crural Arch, form- ed as has been described, is changed in every position. It will clearly appear, also, that the division of the ligament of Pou- part alone, though it may slightly weaken the Crural Arch, cannot be trusted to as a means of relieving strangulation. The division of the falciform process, on the other hand, or its continuation, the femoral ligament, must immediately relax both the arch and its crescentic portion, and by attention to the position of the limb, it will seldom be found necessary to carry the edge of the knife against either of the two last-men- tioned parts. 21 od) to abrwyl dybt ad to moltetor basyallied ads ebrewyi vd hotgifis to nortexsler afifTeto edizzoros dmil er end to endereJ Isromo I to serremoto desuport or not darees lltw de caro doidw si ;atrolow loare robar quillet oloog ni si goed aad en be geggs virsalo els enamed en redtegel Desset ylcommos ex teen ers to anotom sa vd hotosba lle da od idizzog Jomaro Jusquo i ed eidasvommi owl izivled naibretro vaimethe whstar edi dor A TETUTO or to moienes art esered W sued to aiming lliw I maniacq yiovs ai bogando at bodige -204 to tremavil odt to motivib ed) Jedi don A Isurro edit redsey vinigile vam ti dopadli enols dzery meltelugastie quiveller to casem s as of betema ed tommes xi to bred radio era o gessor motiolatedt to solzivih edт xelst vleisthommi jane dhemspil istomet odt noitaumitres and of normalde yd bae noftrog stine2019 aji done od drod at pussssson barot ed mobles lliy di dunil eds to melthog from deaf out on to rectie tenisus stiml aid to sche ont vusə 18 banoj A Drawn by John Alex: Schetley Esq www a PLATE I.
