22例成人股骨头缺血性坏死髋臼软骨病理改变观察

Observations of 22 Cases Degeneration of the Acetebular Cartilage in Osteonecrosis of the Femoral Head

目的 :观察成人股骨头缺血性坏死髋臼软骨变性情况。方法 :从大量该类患者中选择出 17例患者 2 2个髋关节 ,其中 12个为ARCO分期ⅢA ,10个为ⅢB ,手术中取髋臼软骨。结果 :2 0例髋臼软骨有不同程度病理改变。发现股骨头变形程度与髋臼软骨病理改变程度指数密切相关。结论 :结果证实了一个ARCOⅢ期的成人股骨头缺血性坏死髋关节不论年龄大小仅适合做能保护髋臼或能阻止髋臼病变进一步发展的股骨头保留治疗 ,也证实了股骨头置换术比全髋关节置换术在此类患者中效果差这一观点。

Objective:To observe the degeneration of the acetabular cartilage in osteonecrosis of the femoral head. Methods: We selected 22 hips from a large number of patients. There were 12 hips ARCO stage Ⅲ A, 10 hips stage Ⅲ B. Results: We observed the acetabular cartilage of 20 hips degenerated in various degrees, and the results of the degree of collapse of the femoral head was significantly related to the degeneration of the acetabular cartilage on histological examination. Conclusion:The view, is supported by our observations, patient no matter what age with an ARCO stage Ⅲ hip is just to be operated by head-preserving procedures which can protect the acetebular or stop the degeneration of the acetabular cartilage and singular femoral head replacement gives poor result than total hip arthroplasty, in cases of osteonecrosis of the femoral head.
