Imageless navigation has been successfully integrated in knee arthroplasty but its effectiveness in total hip arthroplasty (THA) has been debated. It has consistently been shown that navigation adds significant time and cost to the operation. Further, the relative success of traditional hip replacements has impeded the adoption of new techniques.
We compared the operative time between fifty total hip replacements with and without the use of imageless navigation by a single senior surgeon in a retrospective study. We employed standard statistical tools to compare the two methods. A correlation-based analysis was used to delimit the "learned" phase of imageless navigation to make comparisons meaningful.
Contrary to what has previously been reported, there was no significant difference between operative time in navigated, when compared to traditional operations (p = 0.498). Only fourteen operations were required to delimit the learning phase of this operation.
This is the first study that demonstrates no added operative time when using imageless navigation in THA, achieved with an improved workflow. The results also demonstrate a very reasonable learning curve.
无图像导航已成功应用于膝关节置换术，但其在全髋关节置换术（THA）中的有效性一直存在争议。一直以来都表明，导航会显著增加手术时间和成本。此外，传统髋关节置换术的相对成功阻碍了新技术的采用。
在一项回顾性研究中，我们比较了一位资深外科医生进行的50例使用和不使用无图像导航的全髋关节置换术的手术时间。我们使用标准统计工具比较这两种方法。基于相关性的分析用于界定无图像导航的“学习”阶段，以使比较有意义。
与之前报道的情况相反，与传统手术相比，导航手术的手术时间没有显著差异（p = 0.498）。仅需14例手术即可界定该手术的学习阶段。
这是第一项表明在THA中使用无图像导航时不会增加手术时间的研究，这是通过改进工作流程实现的。结果还显示出非常合理的学习曲线。
