The aim of this study was to introduce a simple and reliable intraoperative reference guide to reproduce the normal femoral anteversion during total hip arthroplasty (THA). We hypothesized that the posterior lesser trochanter line (PLTL) could be a useful guide for estimating femoral anteversion during THA. We conducted a study of 56 men (112 hips) to evaluate the relationship between the PLTL and the femoral anteversion using computed tomography scans. The mean femoral anteversion was 9.0° ± 8.1° (range, -16.2° to 32.9°). The PLTL angle correlated (r(2) = 0.12, P < 0.05) with the femoral anteversion. We found a constant relationship between the PLTL and femoral anteversion, and the PLTL may be used as a guide for estimating the femoral stem anteversion during femoral stem fixation.
本研究旨在介绍一种简单可靠的术中参考指南,以在全髋关节置换术(THA)中重现正常的股骨前倾角。我们假设后小转子线(PLTL)可作为估计 THA 中股骨前倾角的有用指南。我们对 56 名男性(112 髋)进行了一项研究,以使用计算机断层扫描评估 PLTL 与股骨前倾角之间的关系。平均股骨前倾角为 9.0°±8.1°(范围,-16.2°至 32.9°)。PLTL 角度与股骨前倾角呈相关性(r²=0.12,P<0.05)。我们发现 PLTL 与股骨前倾角之间存在恒定的关系,PLTL 可作为在股骨柄固定过程中估计股骨柄前倾角的指南。
