Anatomic considerations for the choice of surgical approach for hip resurfacing arthroplasty.
A number of surgical exposures have been advocated over the past 20 years by the pioneers of resurfacing hip arthroplasty and include the anterior, anterolateral, lateral, and posterolateral approaches. Not all of these approaches, however, appear to provide adequate exposure while respecting the local biology that seems to be imperative for the procedure. Based on an anatomic study, the most "bio-logical" surgical approach for hip resurfacing arthroplasty appears to be through a lateral or posterolateral approach using a digastric trochanteric osteotomy combined with an anterior hip dislocation. These exposures avoid injury to the medial femoral circumflex artery supplying the femoral head and allow access and treatment to the commonly observed hip pathologies that are frequently located anteriorly.
