Acetabular cup positioning with respect to inclination and anteversion is important in total hip arthroplasty. Positioning affects wear, range of motion, dislocation, and aseptic loosening and is essential for the prognosis after surgery. In this study, we sought to determine the accuracy of surgeons' cup positioning and to test for any differences in accuracy among surgeons with different levels of surgical experience. Using a lateral transgluteal approach, 2 groups of surgeons with different levels of surgical experience positioned 85 cups. Fifty-nine percent of the cups were outside the safe zone of Lewinnek. There was no significant difference between the 2 groups.
在全髋关节置换术中，髋臼杯相对于倾斜度和前倾角的定位很重要。定位会影响磨损、活动范围、脱位和无菌性松动，并且对于手术后的预后至关重要。在本研究中，我们试图确定外科医生杯定位的准确性，并测试不同手术经验水平的外科医生在准确性上是否存在差异。采用经臀外侧入路，两组具有不同手术经验水平的外科医生放置了85个髋臼杯。59%的髋臼杯位于Lewinnek安全区之外。两组之间没有显著差异。
