Mini-posterior approach for primary total hip arthroplasty

Total hip arthroplasty (THA) can be performed safely and with excellent patient outcomes through a wide variety of surgical approaches. In recent years, the advent of so-called ‘minimally-invasive’ surgical approaches has included developments in the surgical approach for THA. The mini-posterior approach (MPA) is one such approach, typically defined as incorporating a standard posterior joint access with more limited muscular dissection and/or incision length <10 cm. This review will attempt to define the MPA, review the available literature on this technique, and discuss the surgical technique in detail.
