作者最近遇到了一位65岁的女性髋关节顽固性疼痛，临床诊断为骨坏死。她接受了全髋关节置换术。组织学上，最引人注目的发现是存在软骨下骨折，伴随着骨痂形成和沿着骨折线两侧的肉芽组织。没有先前骨坏死的证据。病理诊断为股骨头软骨下骨折。这是第一个病例报告证实存在不足的股骨头软骨下骨折的肉眼和显微镜检查。由于不全性软骨下骨折的治疗和管理与骨坏死完全不同，因此区分这两种情况很重要。
The authors recently encountered a 65-year-old osteoporotic woman who had had intractable pain in the hip joint that was diagnosed clinically as osteonecrosis. She was treated by total hip replacement. Histopathologically, the most striking finding was the presence of a subchondral fracture with associated callus formation and granulation tissue along both sides of the fracture line. There was no evidence of antecedent osteonecrosis. This case was diagnosed histopathologically as insufficiency subchondral fracture of the femoral head. This is the first case report to substantiate the presence of insufficiency subchondral fracture of the femoral head by both gross and microscopic examination. Because the treatment and management of insufficiency subchondral fracture are entirely different from osteonecrosis, it is important to differentiate between these two conditions.
