Avascular Necrosis of the Femoral Head After Covid-19: A Case Report

Abstract

Avascular necrosis of the femoral head can traumatic or non-traumatic in origin. Embolism (hemoglobinopathies, dysbaric osteonecrosis), corticosteroid treatment, alcohol usage, pelvic irradiation, and genetic susceptibility are among the causes of this clinical entity. Pathogenesis is influenced by thrombophilia, hypofibrinolysis, and hypoangiogenesis. Coronavirus disease 2019 (COVID-19) infection stands as a cause of non-traumatic osteonecrosis of the femoral head. The condition can be related to the use of corticosteroids throughout the disease course of COVID-19. Yet, there could be other disease-related factors that may contribute to the development of osteonecrosis of the femoral head. The current article aimed to present a case with COVID-19 associated avascular necrosis of the femoral head.
