多项研究表明，在全髋关节置换术（THA）中，使用计算机导航系统而非徒手对线方法可以更好地放置髋臼杯和股骨柄。然而，尚未比较使用计算机导航与手动术中测量器械的相关临床优势。本研究旨在确定与使用测量器械相比，使用计算机导航是否可以改善术后下肢不等长（LLD）。我们进行了一项回顾性研究，比较了30例计算机辅助THA与40例使用简单手动测量器械进行的THA。计算机辅助组的术后LLD为3.0 mm（范围：0 - 8 mm），器械组为2.9 mm（范围：0 - 10 mm）。两组间差异无统计学意义。结果表明，使用基于计算机断层扫描的导航和简单的手动测量设备，腿长得到了很好的均衡。
Several studies have shown that better placement of the acetabular cup and femoral stem can be achieved in total hip arthroplasty (THA) by using the computer navigation system rather than the free-hand alignment methods. However, there have been no comparisons of the relevant clinical advantages in using the computer navigation as opposed to the manual intraoperative measurement devices. The purpose of this study is to determine whether the use of computer navigation can improve postoperative leg length discrepancy (LLD) compared to the use of the measurement device. We performed a retrospective study comparing 30 computer-assisted THAs with 40 THAs performed using a simple manual measurement device. The postoperative LLD was 3.0 mm (range, 0 to 8 mm) in the computer-assisted group and 2.9 mm (range, 0 to 10 mm) in the device group. Statistically significant difference was not seen between the two groups. The results showed good equalization of the leg lengths using both computed tomography-based navigation and the simple manual measurement device.
