Osteochondritis dissecans in a few cases may complicate Perthes' disease. A review of the literature shows 27 published cases. The authors have personally observed 6 cases. The age of the patient was older than in most Perthes' disease. All were male. This condition is diagnosed by the presence of a persisting irregularity of the femoral head with abnormal texture. The clinical signs are not obvious except in cases of recurrent locking where there is a loose body. The avascular fragment is visible on standard radiographs and is best recognised by arthrography. Conservative treatment should be given when the disability is moderate. The loose body should be removed surgically when it is mobile, when it bulges into the joint space or when there are signs of early arthrosis.
少数情况下，剥脱性骨软骨炎可能并发佩特兹病。文献回顾显示有27例已发表病例。作者个人观察到6例。患者年龄比大多数佩特兹病患者的年龄大。均为男性。这种情况通过股骨头持续存在不规则且质地异常来诊断。除了复发性交锁且有游离体的病例外，临床体征并不明显。标准X线片上可见无血管的碎片，关节造影能更好地识别。当残疾程度为中度时应给予保守治疗。当游离体可活动、突入关节间隙或有早期关节炎迹象时，应手术切除。
