我们评估了 15 名患有髋臼突出的类风湿性关节炎患者的 19 个髋关节，这些患者已接受使用支撑环的全髋关节置换术 (THA) 手术治疗；四个髋部被替换为 TACT 杯支架，一个髋部被替换为 Kerboull 板，六个髋部被替换为 Ganz 环，八个髋部被替换为 Muller 环。平均年龄为60.2岁（范围4875岁），平均随访时间为38个月（范围6-74个月）。两名患者（三髋）在最终随访前死亡，两名患者（两髋）因 Ganz 环松动而接受翻修。根据日本骨科学会髋关节功能评价表（JOA评分）对髋关节功能进行评分。术前平均 JOA 总分为 25.2 +/- 8.6，术后为 55.6 +/- 8.7。从放射线照片上看，17 个髋关节（减去两个修改过的髋关节）显示骨移植物融合良好，并且支撑环没有松动。这17个髋关节髋臼突出的平均深度为术前3.5±4.1mm，术后即刻2.8±5.1mm，末次随访时2.3±3.9mm（临界率5%时无显着差异）。我们的研究表明，使用骨移植物和支撑环进行 THA 对患有髋臼突出的 RA 患者非常有用。
We evaluated 19 hips of 15 rheumatoid arthritis patients with protrusio acetabuli that had been surgically treated with total hip arthroplasty (THA) using a support ring; four hips were replaced with a TACT cup supporter, one hip with a Kerboull plate, six hips with a Ganz ring, and eight hips with a Muller ring. The average age was 60.2 years (range 4875 years), and the average follow-up was 38 months (range 6-74 months). Two patients (three hips) died before the final follow-up, and two patients (two hips) underwent revision owing to loosening of the Ganz ring. Hip functions were rated according to the evaluation chart of hip joint functions of the Japanese Orthopaedic Association (JOA score). The mean total JOA score was 25.2 +/- 8.6 preoperatively and 55.6 +/- 8.7 postoperatively. Radiographically, 17 hips (minus the two revised hips) showed satisfactory incorporation of bone graft and no loosening of the support ring. The mean depth of protrusio acetabuli for these 17 hips was 3.5 +/- 4.1 mm before operation, 2.8 +/- 5.1 mm just after operation, and 2.3 +/- 3.9mm at the final follow-up (no significant difference at the critical rate of 5%). Our study indicated the usefulness of THAs using a bone graft and a support ring in RA patients with protrusio acetabuli.
