We report outcomes on 120 Birmingham Hip Resurfacings (BHRs) (mean age 50 years) at a minimum of ten-years follow-up. Cases were performed by one surgeon and included his learning curve. Six hips were revised, with no revisions for infection, dislocation, or adverse reaction to metal debris. Ten-year survival was 94.2% (95% confidence interval (CI) 88.8%-98.7%) for all revisions and 96.1% (95% CI 91.5%-99.8%) for revisions for aseptic loosening. Gender (P = 0.463) and head size (P = 0.114) did not affect revision risk. Mean post-operative Harris hip score was 84.0. Contrary to previous independent reports, good outcomes into the second decade were achieved with the BHR in both men and women. Longer term follow-up will confirm whether these promising outcomes in women continue.
我们报告了120例伯明翰髋关节表面置换术（BHR）（平均年龄50岁）至少十年的随访结果。这些病例均由同一位外科医生实施，涵盖了其学习曲线阶段。有6例髋关节进行了翻修，未出现因感染、脱位或对金属碎屑不良反应而进行翻修的情况。所有翻修病例的十年生存率为94.2%（95%置信区间（CI）88.8%-98.7%），无菌性松动翻修病例的十年生存率为96.1%（95%CI 91.5%-99.8%）。性别（P = 0.463）和股骨头大小（P = 0.114）不影响翻修风险。术后Harris髋关节评分平均为84.0。与之前的独立报告相反，BHR在男性和女性中均在第二个十年取得了良好的结果。长期随访将证实女性中这些有前景的结果是否会持续。
