BACKGROUND
The outcomes of revision total hip arthroplasty (rTHA) have become increasingly important as their volume increases. Computer navigation, a reliable method to improve component positioning during primary total hip arthroplasty (THA), is not well studied in the rTHA setting. Given that dislocation rates following rTHA are significantly higher than those of primary THA, component positioning becomes paramount in these cases.
METHODS
Here, we present two case reports and surgical techniques, one of a 77-year-old man undergoing rTHA for recurrent hip instability following primary THA, and one of a 61-year-old woman undergoing rTHA for severe iliopsoas bursitis who was at increased risk for instability and dislocation given her history of large segment spinal fusion.
RESULTS
Both patients achieved optimal acetabular component positioning after rTHA with imageless computer navigation.
CONCLUSIONS
The use of imageless computer navigation in rTHA provides accurate and reproducible component positioning during acetabular rTHA.
背景
随着翻修全髋关节置换术（rTHA）数量的增加，其手术效果变得越来越重要。计算机导航作为一种在初次全髋关节置换术（THA）中改善假体定位的可靠方法，在rTHA中的研究并不充分。鉴于rTHA后的脱位率明显高于初次THA，在这些病例中假体定位至关重要。
方法
在此，我们展示两个病例报告及手术技术，一个是77岁男性，因初次THA后复发性髋关节不稳定接受rTHA；另一个是61岁女性，因严重髂腰肌滑囊炎接受rTHA，鉴于其有大段脊柱融合病史，她发生不稳定和脱位的风险增加。
结果
两名患者在rTHA后通过无影像计算机导航均实现了髋臼假体的最佳定位。
结论
在rTHA中使用无影像计算机导航可在髋臼rTHA期间提供准确且可重复的假体定位。
