This rise is directly related to the increasing numbers of primary and revision hip arthroplasties being performed and the aging of the population. The Vancouver classification is the most widely used classification system for periprosthetic fractures of the femur occurring after hip arthroplasty. This classification considers the location of the fracture in relation to the femoral stem, the stability of the femoral stem, and the availability of femoral bone stock for revision. Most Vancouver AG and AL fractures can be treated nonsurgically, the exceptions being fractures associated with osteolysis and clamshell fractures of the lesser trochanter. B and C type fractures usually require operative intervention. Both Vancouver B1 and C types can be treated with fracture fixation alone, as the femoral implant is stable. Vancouver types B2 and B3 require femoral revision as the implant is loose. Distinguishing between types B1 and B2 can be difficult from radiographs alone and may require computed tomography and intraoperative testing.</p>","PeriodicalId":72481,"journal":{"name":"Bulletin of the Hospital for Joint Disease (2013)","volume":" ","pages":"98-107"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39057971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We retrospectively reviewed 75 fluoroscopically assisted DAA-THA performed by a single surgeon: 37 procedures used the software intraoperatively to overlay anteversion, inclination, and leg length information over the existing fluoroscopic radiograph with the aim of enhancing component positioning. The control group consisted of 38 procedures from the single surgeon's patient pool who had undergone non-navigated fluoroscopic assisted DAA-THA 1 month prior to the system's trial. Our results demonstrate that the navigation group measurements were significantly closer to the target numbers with less variation. The mean difference from target value were as follows: for anteversion (control: -4.68°, navigated: -01.0°), inclination (control: -1.87°, navigated: 0.8°), and leg length discrepancy (control: -2.59°, navigated: -0.98°). In addition, surgical time was shorter in the navigation group (75.7 vs. 74 minutes; p = 0.001).
