Abstract

UNLABELLED

We previously reported the 10 to 13-year follow-up results for 104 total hip replacements with the Zweymüller Alloclassic stem and a threaded cup in 94 patients. The present study is a clinical and radiographic outcome update after a minimum follow-up of 25 years. Four patients (4 hips) were lost and 46 patients (50 hips) died, leaving 44 patients (50 hips) available for follow-up. Since our previous report, 7 cups and 2 stems were revised. At 20 years, the probability of survival of any component was 84.1% (95% confidence interval [CI], 73.91% to 94.29%) and the cumulative probability of not having stem loosening was 95.9% (95% CI, 95.51% to 96.29%). We observed proximal femoral osteolysis in 15 hips (30%), cortical hypertrophy in 21 hips (42%), and proximal femoral osteopenia in 30 hips (60%). The Zweymüller Alloclassic stem continues to provide excellent results after extended follow-up.

摘要

未标注

我们之前报告了94例患者使用Zweymüller Alloclassic柄和螺纹髋臼杯进行的104例全髋关节置换术的10至13年随访结果。本研究是在至少25年随访后的临床和影像学结果更新。4例患者（4髋）失访，46例患者（50髋）死亡，剩余44例患者（50髋）可供随访。自我们之前的报告以来，7个髋臼杯和2个股骨柄进行了翻修。在20年时，任何部件的生存率为84.1%（95%置信区间[CI]，73.91%至94.29%），无股骨柄松动的累积概率为95.9%（95%CI，95.51%至96.29%）。我们观察到15髋（30%）出现股骨近端骨溶解，21髋（42%）出现皮质肥厚，30髋（60%）出现股骨近端骨质减少。延长随访后，Zweymüller Alloclassic柄继续提供优异的结果。
