Between 1986 and 1991 we implanted 331 consecutive Furlong hydroxyapatite-coated femoral components of a total hip replacement in 291 patients. A cemented acetabular prosthesis was used in 217 hips and a hydroxyapatite-coated component in 114. We describe the long-term clinical and radiological survival of the femoral component at a mean follow-up of 17.5 years (15 to 21). Only two patients (0.68%) were lost to follow-up. With revision of the femoral component for any reason as the endpoint, the survival at a mean of 17 years was 97.4% (95% confidence interval 94.1 to 99.5), and with revision for aseptic loosening as the endpoint it was 100%. The survival at a maximum of 21 years with revision of the femoral component for any reason as the endpoint was 97.4% (95% confidence interval 81.0 or 99.5). These results compare favourably with the best long-term results of cemented or uncemented femoral components used in total hip replacement.
1986年至1991年间，我们为291例患者连续植入了331个Furlong羟基磷灰石涂层全髋关节置换股骨组件。217髋使用了骨水泥固定髋臼假体，114髋使用了羟基磷灰石涂层组件。我们描述了平均随访17.5年（15至21年）时股骨组件的长期临床和放射学生存率。仅2例患者（0.68%）失访。以因任何原因翻修股骨组件为终点，平均17年时的生存率为97.4%（95%置信区间94.1至99.5），以无菌性松动翻修为终点时生存率为100%。以因任何原因翻修股骨组件为终点，最长21年时的生存率为97.4%（95%置信区间81.0或99.5）。这些结果优于全髋关节置换中使用的骨水泥固定或非骨水泥固定股骨组件的最佳长期结果。
