Idiopathic chondrolysis of the hip is characterized by the destruction of the articular cartilage due to an unknown cause, principally affecting women during adolescence and producing premature degeneration of the hip. Twelve cases (11 patients) were reviewed at our hospital, with an average follow-up period of 13.2 years, during which a clinical and radiologic study was performed. Despite the treatment implemented, idiopathic chondrolysis of the hip causes progressive degeneration of the joint with the appearance of almost constant pain, stiffness, and anomalous positions. Radiologic studies show concentric narrowing of the articular space, decrease in the width of the femoral head and neck, and shortening of the affected member due to alteration in the growth physis of the upper extremity of the femur.
特发性髋关节软骨溶解症的特征是关节软骨因不明原因遭到破坏，主要影响青春期女性，并导致髋关节过早退变。我院对12例（11名患者）进行了回顾性研究，平均随访期为13.2年，在此期间进行了临床和影像学研究。尽管采取了治疗措施，但特发性髋关节软骨溶解症仍会导致关节进行性退变，并出现几乎持续不断的疼痛、僵硬和畸形体位。影像学研究显示关节间隙同心性变窄、股骨头和颈宽度减小，以及由于股骨上端生长板改变导致患侧肢体缩短。
