The minimal invasive surgery anterior approach with supine patient positioning: a step-wise introduction of technique

The purpose of the review is to report the modified Smith-Peterson technique for use with minimal invasive total hip arthroplasty (MIS THA) with supine patient positioning. The modified Smith-Peterson technique allows for direct visualisation of the acetabulum and is an internerval approach. The MIS anterior approach with supine patient positioning offers a complete intermuscular and internervous access to the hip joint. The use of this technique yields a reduction of muscular trauma, intraoperative bloodloss, and postoperative rehabilitation. The reduction of soft tissue trauma may lead to minimal postoperative pain. While cosmesis is never a reason for using MIS, it does yield great patient satisfaction. The MIS anterior approach with supine patient positioning is a safe and reproducible method, offering an alternative option in MIS THA.
