Serial radiographs of 241 consecutive, noninfected low friction arthroplasties performed between 1968 and 1972 were evaluated with respect to socket migration and the presence of radiolucencies, progressive or not. The number of intact sockets in 207 cases of arthrosis decreased slowly and, depending on their classification, approached 95-88 per cent about 10 years postoperatively. Contrary to previous reports, we could not observe any increase in the rate of loosening with time; half of the hips were observed for more than 10 years, and only a few cases of socket loosening were found beyond this point. In rheumatoid arthritis the number of intact sockets was significantly fewer--23 of 34--after about 10 years of service.
对1968年至1972年间连续进行的241例未感染的低摩擦关节成形术的系列X线片进行了评估，观察髋臼的移位情况以及有无透亮线（无论是否进展）。207例关节病患者中髋臼完整的数量缓慢减少，根据其分类，术后约10年时接近95% - 88%。与先前的报道相反，我们未观察到松动率随时间增加；一半的髋关节观察时间超过10年，在此之后仅发现少数髋臼松动病例。在类风湿性关节炎患者中，使用约10年后髋臼完整的数量明显较少，34例中仅有23例。
