BACKGROUND
This study presents the results of the long-term survival of a wedge-shaped uncemented femoral component in a cohort of young patients with a follow-up of 20-25 years.
METHODS
In a consecutive series of 85 patients (100 hips), aged less than 50 years at the time of primary total hip arthroplasty, the long-term survival of the Cementless Spotorno femoral component was analyzed by performing a Kaplan-Meier survival analysis (95% confidence interval [CI]).
RESULTS
The mean follow-up was 22 years (range, 19.7-25.5). The clinical and radiographic outcomes were satisfactory. The overall survival rate of the femoral component was 93.4% after 23.8 years (95% CI, 85.9%-97.0%). Survival with revision for aseptic loosening as the end point was 94.4% (95% CI, 87.0%-97.6%) after 23.8 years.
CONCLUSION
This study shows an excellent long-term survival of this specific wedge-shaped uncemented femoral component after 20 to 25 years in patients younger than 50 years.
背景
本研究报告了一组年轻患者（随访 20-25 年）中使用楔形非骨水泥股骨部件的长期生存结果。
方法
在连续的 85 例患者（100 髋）中，在初次全髋关节置换时年龄小于 50 岁，通过 Kaplan-Meier 生存分析（95%置信区间[CI]）分析非骨水泥 Spotorno 股骨部件的长期生存情况。
结果
平均随访时间为 22 年（范围，19.7-25.5）。临床和影像学结果令人满意。23.8 年后，股骨部件的总体生存率为 93.4%（95%CI，85.9%-97.0%）。以无菌性松动为终点的翻修生存率为 23.8 年后的 94.4%（95%CI，87.0%-97.6%）。
结论
本研究表明，在 20-25 年后，50 岁以下患者使用特定的楔形非骨水泥股骨部件具有优异的长期生存率。
