From our first 186 Charnley hip replacements 125, retained for more than 10 years, were examined clinically and radiographically. There were radiographic signs of definite or probable loosening of one or both prosthetic components in 29 per cent of the hips. However, there was a poor correlation between the clinical and the radiographic results, as 86 per cent of the hips were free from significant pain. The loosening rate for males under 60 years of age at the time of the operation was four times higher than for females in the same age group. We suggest that this high-risk group should be followed radiographically, so that a revision, if necessary, can be considered while the bone stock is still sufficient.
在我们最初进行的186例Charnley髋关节置换手术中，对125例保留超过10年的病例进行了临床和影像学检查。29%的髋关节出现了一个或两个假体组件明确或可能松动的影像学迹象。然而，临床结果与影像学结果之间的相关性较差，因为86%的髋关节没有明显疼痛。手术时年龄在60岁以下的男性松动率是同年龄组女性的四倍。我们建议对这个高风险群体进行影像学随访，以便在骨量仍然充足时，如有必要可考虑进行翻修手术。
