We report the results of impaction bone grafting of the femoral side in revision total hip arthroplasty in Asian hips (South Korean patients) in which the surgery was performed with the use of the Exeter stem. The minimum follow-up was 39 months (mean, 48.4; range, 39-66). There was subsidence of the cement-graft interface (<1 mm) in three hips (5%), of the stem-cement interface (<1 mm) in 12 hips (21%) and of the stem-cement interface (1-2 mm) in 14 hips (25%). Five hips (9%) developed intraoperative femoral fracture and two hips (4%) femoral perforation in revision. The complications of femoral fracture and subsidence did not have an adverse effect on the final clinical outcomes. The impaction of fresh-frozen allograft and use of a cemented, polished, tapered stem (Exeter stem) were also successful with good clinical and radiographic outcomes in our study of Asian hips (South Korean patients). However, we used smaller stems than the usual ones used for Western patients because of the smaller femur sizes.
我们报告了在亚洲髋部（韩国患者）翻修全髋关节置换术中使用埃克塞特柄进行股骨侧打压植骨的结果。最短随访时间为39个月（平均48.4个月；范围39 - 66个月）。3例髋关节（5%）出现骨水泥 - 植骨界面下沉（<1 mm），12例髋关节（21%）出现柄 - 骨水泥界面下沉（<1 mm），14例髋关节（25%）出现柄 - 骨水泥界面下沉（1 - 2 mm）。5例髋关节（9%）在翻修术中发生术中股骨骨折，2例髋关节（4%）发生股骨穿孔。股骨骨折和下沉并发症对最终临床结果没有不良影响。在我们对亚洲髋部（韩国患者）的研究中，新鲜冷冻同种异体骨的打压植骨以及使用骨水泥固定、抛光、锥形柄（埃克塞特柄）也取得了成功，临床和影像学结果良好。然而，由于股骨尺寸较小，我们使用的柄比用于西方患者的通常尺寸更小。
