To evaluate the safety of using extended trochanteric osteotomy (ETO) in a 2-stage revision of periprosthetic hip infection, we performed a retrospective review of 23 patients using ETO in the revision of infected hip arthroplasty and compared them to 46 patients using ETO in the revision of noninfected hip arthroplasty. Harris Hip Score improved from 36 points preoperatively to 82 points postoperatively. Infection was eradicated in 22 patients (96%). ETO healed in all at a mean of 10.6 weeks. No stem was revised for aseptic loosening. Complications included 2 periprosthetic fractures, 1 peroneal nerve palsy, and 1 dislocation. Postoperative Harris Hip Score, ETO union rate, time to healing of ETO, stem stability, and complication rate did not differ between the 2 groups. Our data suggest that ETO can be safely used in treating periprosthetic hip infection.
为了评估在髋关节假体感染的两期翻修中使用延长转子截骨术（ETO）的安全性，我们对 23 例使用 ETO 治疗感染性髋关节置换翻修的患者进行了回顾性研究，并将其与 46 例使用 ETO 治疗非感染性髋关节置换翻修的患者进行了比较。Harris 髋关节评分从术前的 36 分提高到术后的 82 分。22 例（96%）患者感染得到根除。所有患者的 ETO 平均在 10.6 周内愈合。没有因无菌性松动而修改柄。并发症包括 2 例假体周围骨折、1 例腓总神经麻痹和 1 例脱位。两组患者术后 Harris 髋关节评分、ETO 愈合率、ETO 愈合时间、柄稳定性和并发症发生率无差异。我们的数据表明，ETO 可安全用于治疗髋关节假体周围感染。
