摘要

背景:高度多孔的小梁金属(Trabecular Metal™)髋臼假体越来越多地用于髋关节翻修成形术,因为它们促进髋关节内生长,提供了一种有效的机制来处理骨质流失,并可能降低感染的风险。本次审核的目的是描述:1)五年内髋关节置换术的总数,翻修与初次髋关节置换术的比例和翻修指征;2)金属小梁(Trabecular Metal™)组件和增强物翻修髋关节置换术的短期疗效。方法:回顾性分析2012年2月至2017年2月在某三级医院行翻修型全髋关节置换术(THA)患者的资料和x线片。结果:在此期间共进行了979例髋关节置换术,其中原发性髋关节置换术863例(87%),髋关节翻修术116例(12%)。在116例(107例)髋关节翻修中,5例患者中有7例(6%)再次翻修。翻修指征为无菌性松动67例(59%),感染性松动11例(10%),衬套磨损18例(16%),假体周围骨折5例(4%),其他15例(13%)。Trabecular Metal™用于16髋(14例患者)的翻修,占116例翻修总数的14%。其中女性10名,男性4名,平均年龄61岁。本组患者平均随访时间为18.5个月(1.5 ~ 39.2个月)。在这16例金属小梁(Trabecular Metal™)髋关节中,有3例(19%)由于技术错误导致早期固定失败。结论:在我院,12%的关节置换术为翻修手术。修订的适应症与已发表的文献相似。由于技术错误,小梁金属矫正术的早期失败率为19%。证据等级:四级

The short-term outcome of hip revision arthroplasty with Trabecular Metal™ components and augments
Background: Highly porous Trabecular Metal™ acetabular components are increasingly being used in revision hip arthroplasty as they facilitate ingrowth, provide a useful mechanism to deal with bone loss and may decrease the risk of infection. The purpose of this audit was to describe: 1) the total number of hip arthroplasty surgeries over five years, the ratio of revision to primary hip arthroplasty and indications for revision; 2) the short-term outcomes of revision hip arthroplasty with Trabecular Metal™ components and augments.  Methods: A retrospective folder and radiograph review of all patients who had revision total hip arthroplasty (THA) at a tertiary level hospital from February 2012 to February 2017 was done. Results: There were 979 THAs performed over the period – 863 (87%) primary THAs, and 116 (12%) hip revision cases performed in 107 patients. Of the 116 (107 patients) hip revisions, there were seven (6%) re-revisions in five patients. The indications for revision were aseptic loosening 67 (59%), septic loosening 11 (10%), liner wear 18 (16%), periprosthetic fracture five (4%), other 15 (13%). Trabecular Metal™ was used for revision in 16 hips (14 patients), which is 14% of the total 116 revisions. There were ten females and four males with an average age of 61 years. The average duration of follow-up in this group was 18.5 months (1.5–39.2). In these 16 Trabecular Metal™ hips, there were three (19%) early failures of fixation due to technical errors. Conclusion: In our institution, 12% of the arthroplasty is revision surgery. The indications for revision are similar to published literature. Trabecular Metal™ revisions had a 19% early failure rate due to technical error. Level of evidence: Level 4
