In a retrospective study of 539 patients with SARS who received corticosteroid therapy, 5 the incidence of steroid-induced ONFH was 24%, and increased incidence of steroidinduced ONFH was associated with total corticosteroid dose and the use of more than one type of corticosteroid. Improper or delayed treatment of steroid-induced ONFH can cause hip pain, claudication, and even disability of the lower limbs. Overall, we call for caution in the use of corticosteroids for COVID-19 and do not recommend this as a routine treatment. To prevent steroidinduced ONFH, corticosteroids should be considered only for patients undergoing septic shock, or in critical cases. 6, 7 Corticosteroids should be minimised in dose and duration, and the use of multiple types should be avoided. We believe that bisphosphonates and vitamin E should be prescribed to patients who are undergoing corticosteroid treatment; anticoagulants, vasodila tors, and traditional Chinese medicine could also be considered. [8] [9] [10] Close follow-up should be conducted after discharged, with MRI as the best option for early detection of ONFH. Physical therapy and combined pharmacotherapy have been recommended for patients with early-stage steroid-induced ONFH. 11 We declare no competing interests.
