A planned change in the prosthesis used for hip hemiarthroplasty in one orthopaedic trauma unit from the Thompson prosthesis to the Exeter Trauma Stem (ETS) was studied. We completed a prospective continuous audit study comparing outcomes for patients undergoing the procedure before (766 patients) and after (388 patients) the change of practice. Outcomes measured included surgical complications (including infection or dislocation) and a postoperative radiographic review. There was no difference in the incidence of surgical complications between the groups, and no difference in ratings given to postoperative radiographs between both groups. In theory, the ETS may be easier to revise, should this be required in future, but in other respects the devices are comparable.
一项针对某骨科创伤科髋关节半关节置换术所用假体从汤普森假体改为埃克塞特创伤柄（ETS）的计划变更进行了研究。我们完成了一项前瞻性连续审计研究，比较了在实践变更之前（766例患者）和之后（388例患者）接受该手术的患者的结局。所测量的结局包括手术并发症（包括感染或脱位）以及术后影像学复查。两组之间手术并发症的发生率没有差异，两组对术后X线片的评分也没有差异。理论上，如果未来有需要，ETS可能更容易翻修，但在其他方面，这两种假体具有可比性。
