The purpose of this study was to evaluate the outcome of trabecular metal (TM) acetabular components used in revision hip arthroplasty with major bone deficiency. We retrospectively reviewed the records of 46 patients undergoing revision hip arthroplasty with severe acetabular bone loss. Clinical outcomes were assessed using Harris Hip Score, Western Ontario and McMaster Universities, and Short-Form 12. Mean follow-up was 50 months. All patients had Paprosky type IIc or III acetabular bone deficiency. Major complications included 1 infection, 2 dislocations, and 1 arterial bleeding. Average Harris Hip Score was 78.2. Short-Form 12 scores were within population-based age-matched averages. Western Ontario and McMaster Universities scores were mainly in the 2 lowest disability categories. Porous tantalum shows promising results in revision arthroplasty with severe acetabular bone loss.
本研究旨在评估在严重髋臼骨缺损的髋关节翻修中使用的多孔钽（TM）髋臼部件的疗效。我们回顾性分析了 46 例严重髋臼骨缺损髋关节翻修患者的病历。采用 Harris 髋关节评分、西安大略和麦克马斯特大学（Western Ontario and McMaster Universities）以及健康调查简表 12 项（Short-Form 12）评估临床疗效。平均随访时间为 50 个月。所有患者均存在 Paprosky Ⅱ c 或 Ⅲ型髋臼骨缺损。主要并发症包括 1 例感染、2 例脱位和 1 例动脉出血。平均 Harris 髋关节评分为 78.2 分。健康调查简表 12 项评分均处于基于人群的年龄匹配平均值范围内。西安大略和麦克马斯特大学评分主要集中在 2 个最低残疾类别。多孔钽在严重髋臼骨缺损的髋关节翻修中显示出良好的效果。
