MORPHOLOGICAL ASPECTS OF ASEPTIC NECROSIS OF THE FEMORAL CAPITIS AFTER COVID-19

Abstract

This study describes the specific pathological changes in aseptic necrosis that developed after COVID19. In this study, 49 patients underwent surgery and the femoral capitis was removed for examination. According to the results of the study, in the late stages of aseptic necrosis, fibro-, chondro-, osteomatous restructuring, the formation of a “fractured membrane” on the surface of the femoral capitis, the appearance of foci of dystrophicdegenerative and destruction-necrosis (melting), chronic non-specific inflammation, between bone trabeculae and pillars, the formation of granulation tissue and the growth of fibroreticular tissue, osteoclast resorption reactions (lacunar).
