Abstract

With the exception of revision osteosynthesis, conversion total hip arthroplasty (CTHA) following sliding hip screw (SHS) and cephalomedullary nail (CMN) failure in intertrochanteric fractures (ITF) is the most commonly used treatment option. This review determined the relative risk of medical and orthopedic complications, including periprosthetic femoral fractures (PFF), following CTHA in failed SHS and CMN fixation of ITF, as well as the Harris hip score (HHS). Major electronic databases were searched for studies and reports on CTHA after SHS and CMN fixation failures in ITF. To assess the risk of bias, the studies were analyzed using the Joanna Briggs Institute critical appraisal tool for cohort studies. Three studies pooled 327 cases and 353 cases of CTHA from failed CMN and SHS in ITF. The relative risk of medical and orthopedic complications and PFF in the SHS group as compared to the CMN group was 0.87 [0.39, 1.90], 1.64 [1.18, 2.29], and 1.92 [0.81, 4.56], respectively. The mean difference in HHS was -0.72 [-1.47, 0.02] between failed SHS and CMN groups. The included studies were of retrospective study design with a more than 20% loss of follow-up and a high risk of bias. There is 64% more risk of orthopedic complications with CTHA in SHS failures than CMN failures. There is no difference in relative risk of medical complications and PFF between CTHA in both SHS and CMN failure. After CTHA, the benefits in function are similar in both groups.

滑动髋关节螺钉和头髓钉失败后的全髋关节置换术:一项系统比较回顾和荟萃分析。
股骨粗隆间骨折(ITF)中,除翻修骨融合术外,滑动髋关节螺钉(SHS)和头髓内钉(CMN)失败后的全髋关节置换术(CTHA)是最常用的治疗选择。本综述确定了医疗和骨科并发症的相对风险,包括假体周围股骨骨折(PFF), CTHA后SHS和CMN固定失败的ITF,以及Harris髋关节评分(HHS)。检索了主要的电子数据库,检索了ITF中SHS和CMN固定失败后CTHA的研究和报告。为了评估偏倚风险,使用乔安娜布里格斯研究所的队列研究关键评估工具对研究进行了分析。3项研究分别收集了327例和353例来自ITF失败CMN和SHS的CTHA。与CMN组相比,SHS组发生内科、骨科并发症及PFF的相对危险度分别为0.87[0.39,1.90]、1.64[1.18,2.29]、1.92[0.81,4.56]。失败SHS组与CMN组HHS的平均差异为-0.72[-1.47,0.02]。纳入的研究为回顾性研究设计,随访损失超过20%,偏倚风险高。SHS失败的CTHA发生骨科并发症的风险比CMN失败的CTHA高64%。在SHS和CMN失败的CTHA中,医疗并发症和PFF的相对风险没有差异。CTHA后,两组在功能上的获益相似。
