Abstract/OtherAbstract:
Controversy exists regarding the ability to position the implants reliably in minimally invasive surgery (MIS) total hip arthroplasty (THA). This study compared the ability to accurately position components in the MIS two-incision versus single-incision approaches. Twenty-four patients were randomized to THA through one of three approaches, including the two-incision approach. Component position was measured with computed tomography. The mean deviation from the target acetabular anteversion was 14.8 degrees in the two-incision MIS group versus 6.4 degrees in the other two approaches (p = 0.006). A mean of 9.8 degrees deviation from the target femoral anteversion in the two-incision MIS approach group was observed compared with 5.3 degrees in the single-incision groups (p = 0.05). These results suggest there is a decreased ability to accurately position the components in the two-incision approach.
