在一个双中心、多外科医生的系列研究中，对463例伯明翰髋关节表面置换术的早期失败率和模式进行了研究。在463名患者中，有2人死亡，3人失访。平均影像学和临床随访时间为43个月（6 - 90），我们翻修了13次表面置换（2.8%），包括7次疼痛，3次骨折，2次脱位和1次败血症。其中，9例有金属沉着的肉眼和组织学证据。全因翻修的5年生存率为95.8%（95%置信区间（CI）94.1 ~ 96.8），金属沉着的5年生存率为96.9%（95% CI 95.5 ~ 98.3），金属沉着相关翻修率为3.1%。金属沉着症的危险因素是女性、股骨部件小、外展角大和肥胖。我们不提倡在有这些风险因素的患者中使用伯明翰髋关节表面置换术。
The rate and mode of early failure in 463 Birmingham hip resurfacings in a two-centre, multisurgeon series were examined. Of the 463 patients two have died and three were lost to follow-up. The mean radiological and clinical follow-up was for 43 months (6 to 90).We have revised 13 resurfacings (2.8%) including seven for pain, three for fracture, two for dislocation and another for sepsis. Of these, nine had macroscopic and histological evidence of metallosis. The survival at five years was 95.8% (95% confidence interval (CI) 94.1 to 96.8) for revision for all causes and 96.9% (95% CI 95.5 to 98.3) for metallosis.The rate of metallosis related revision was 3.1% at five years. Risk factors for metallosis were female gender, a small femoral component, a high abduction angle and obesity. We do not advocate the use of the Birmingham Hip resurfacing procedure in patients with these risk factors.
