We studied all Stanmore total hip arthroplasties (THA, n=325) implanted at our center between 1980 and 1990. Seven patients (seven hips), followed for less than 12 months, were excluded. Five hips were lost at follow-up. The mean follow-up was 117 (12-252) months. A total of 18 hips were revised, with median time between operation and revision 163 months. With revision as endpoint, a survival rate analysis was calculated. The mean survival for all hips was 82% at 18 years (95% confidence interval 64-101%). For hips with rheumatoid arthritis, the survival rate was 58%, whereas in osteoarthritic hips the rate was 95% after 18 years. A high proportion of acetabular loosening was seen in rheumatoid hips.
我们研究了1980年至1990年间在我们中心植入的所有斯坦莫尔全髋关节置换术（THA，n = 325）。7名患者（7髋）随访时间不足12个月，被排除在外。随访中有5髋失访。平均随访时间为117（12 - 252）个月。共有18髋进行了翻修，手术至翻修的中位时间为163个月。以翻修为终点，计算生存率分析。所有髋关节18年时的平均生存率为82%（95%置信区间64 - 101%）。类风湿性关节炎患者的髋关节生存率为58%，而骨关节炎患者的髋关节18年后生存率为95%。类风湿性髋关节中髋臼松动的比例较高。
