We report the survival at five years of 144 consecutive metal-on-metal resurfacings of the hip implanted between August 1997 and May 1998. Failure was defined as revision of either the acetabular or femoral component for any reason during the study period. The survival at the end of five years was 98% overall and 99% for aseptic revisions only. The mean age of the patients at implantation was 52.1 years. Three femoral components failed during the first two years, two were infected and one fractured. A single stage revision was carried out in each case. No other revisions were performed or are impending. No patients were lost to follow-up. Four died from unrelated causes during the study period. This study confirms that hip resurfacing using a metal-on-metal bearing of known provenance can provide a solution in the medium term for the younger more active adult who requires surgical intervention for hip disease.
我们报告了1997年8月至1998年5月间连续植入的144例金属对金属髋关节表面置换术患者的五年生存率。失败定义为在研究期间因任何原因对髋臼或股骨部件进行翻修。五年末的总体生存率为98%，仅无菌性翻修的生存率为99%。植入时患者的平均年龄为52.1岁。在前两年中有三个股骨部件出现故障，两个感染，一个骨折。每种情况均进行了一期翻修。未进行其他翻修，也没有即将进行翻修的情况。没有患者失访。在研究期间有四名患者死于无关原因。这项研究证实，使用已知来源的金属对金属轴承进行髋关节表面置换术可以为因髋关节疾病需要手术干预的更年轻、更活跃的成年人提供中期解决方案。
