【摘要】 目的 研究锥形钛合金多孔表面涂层股骨柄远期生存率和并发症。方法 总共124例患者，行136侧全髋置换术，其中12例患者在随访过程中自然死亡，另有22例在随访中失去联系，余下的90例(96侧THR)平均随访9.6年。从临床疗效和X线检查两方面来分析远期疗效和生存率。结果 所有患者平均Harris评分从58分提高到93分，大腿痛的发生率为3.1%。X线检查分析结果显示在股骨距以下水平没有发现明显的骨吸收现象，仅有1例在术后1年需要行股骨柄翻修。结论 锥形钛合金多孔涂层假体提供了极好的长期稳定性，具有良好的临床使用效果。

    【Abstract】 Objective To study the long-term survivor of a cementless titanium tapered-wedge femoral component.Methods Cementless titanium tapered-wedge femoral stems were implanted in 136 hips in 124 patients.Twelve patients died in 10-year follow-up,and 22 patients were lost during follow-up.The remaining 96 hips were analyzed clinically and radiographically in 9.6 year.Results Harris hip scores improved from 53 to 95,thigh pain was 3.1%.Radiographic analysis revealed no evidence of osteolysis below the level of the calcar and the greater trochanteric region.Only 1 femoral stem was revised at 7 years postoperatively.Conclusion A cementless titanium tapered-werge femoral stem provides excellent long-term fixation,durable clinical outcome. ......
