Idiopathic chondrolysis of the hip (ICH), a very rare disorder of unknown etiology, occurs mainly in female adolescents. Characterized by pain, limp, stiffness and radiological narrowing joint space from the rapid destruction of the articular cartilage, ICH sometimes results in ankyloses. We present the case of a 10-year-old girl diagnosed with ICH based on arthroscopic inspection and synovium biopsy. The femoral deformity appeared gradually, like a cam-type femoroacetabular impingement. She was treated with intensive rehabilitation and immunosuppressive drug. We later performed an arthroscopic bumpectomy for residual symptoms. She achieved a favorable outcome as a 15-year-old at the latest follow-up.
髋关节特发性软骨溶解症（ICH）是一种病因不明的极为罕见的病症，主要发生在青春期女性。其特征为疼痛、跛行、关节僵硬以及因关节软骨迅速破坏导致的影像学上关节间隙变窄，ICH有时会导致关节强直。我们报告一例10岁女孩的病例，该病例经关节镜检查和滑膜活检确诊为ICH。股骨畸形逐渐出现，类似凸轮型股骨髋臼撞击症。她接受了强化康复治疗和免疫抑制药物治疗。后来，针对残留症状我们为她实施了关节镜下骨赘切除术。在最近一次随访时，她15岁，取得了良好的治疗效果。
