The purpose of this study was to evaluate the efficacy of an uncemented tapered femoral component in obese patients at a mean follow-up of 23 years. We retrospectively reviewed 119 consecutive uncemented total hip arthroplasties in 105 obese patients using a tapered femoral component between 1983 and 1987. The mean body mass index of these patients was 34 (range 30-47). Complete clinical and radiographic follow-up was obtained on the 55 hips in 47 patients who survived a minimum of 18 years (range 18-27 years). Three femoral components (6%) have been revised, none for aseptic loosening. One was loose by radiographic criteria. These results demonstrate that an uncemented tapered stem can provide excellent fixation in obese patients out to 27 years.
本研究旨在评估在肥胖患者中使用非骨水泥锥形股骨柄的疗效，平均随访 23 年。我们回顾性分析了 1983 年至 1987 年间使用锥形股骨柄的 105 例肥胖患者的 119 例连续非骨水泥全髋关节置换术。这些患者的平均体重指数为 34（范围 30-47）。对存活至少 18 年（范围 18-27 年）的 47 例患者中的 55 髋进行了完整的临床和影像学随访。3 个股骨组件（6%）已进行了翻修，均非无菌性松动所致。其中 1 个根据影像学标准松动。这些结果表明，非骨水泥锥形柄在肥胖患者中可提供长达 27 年的优异固定效果。
