Surgeons are looking to use computer computer-assisted surgery (CAS) in total hip arthroplasty (THA) in order to quantify leg length measurement, angular cup placement, and enhance stability to provide enhanced accuracy in implant placement. As a result, CAS in THA is gaining popularity. This technology employs the use of pins and provides the surgeon with real-time feedback on positioning intraoperatively. Previous total knee arthroplasty (TKA) literature has reported pin-associated complications such as infections, neuropraxia, and suture abscess. To our knowledge, there have been reports of tibial stress fracture after CAS TKA, but this is the first report of a pin causing fracture of the greater trochanter leading to dislocation in THA. Further studies may be warranted to optimize pin placement for trackers to prevent fractures of the greater trochanter.
外科医生希望在全髋关节置换术（THA）中使用计算机辅助手术（CAS），以便量化腿长测量、髋臼角度放置，并增强稳定性，从而提高植入物放置的准确性。因此，THA中的CAS越来越受欢迎。这项技术使用销钉，并在术中为外科医生提供关于定位的实时反馈。先前的全膝关节置换术（TKA）文献报道了与销钉相关的并发症，如感染、神经失用和缝线脓肿。据我们所知，有关于CAS TKA后胫骨应力性骨折的报道，但这是第一例销钉导致大转子骨折并导致THA脱位的报告。可能需要进一步研究以优化用于跟踪器的销钉放置，以防止大转子骨折。
