[Comparison of total hip arthroplasty via a posterior mini-incision versus a classic anterolateral approach].
Surgical approaches to the hip for total hip arthroplasty ( THA ) are termed minimally invasive when allowing for a skin incision length of 10 cm or less . The aim of this study was to explore if a minimally invasive posterior approach compared to a classic anterolateral approach negatively influenced surgical time , blood loss , implant position , or perioperative complications .  Two groups of THA patients mainly differing with respect to the surgical approach were compared . Results of 76 consecutive THA via a posterior mini-incision approach were recorded prospect ively and those of 76 controls operated via a classic anterolateral approach were recorded retrospectively .  THA was performed by the same surgeon in every case . Surgical time or intraoperative blood loss were not different among the groups . Total 24-h blood loss was significantly less in patients undergoing THA via minimally invasive posterior  approaches . Median cup inclination was 45 degrees in both groups . Cup anteversion was 15 degrees ( classic anterolateral ) and 12 degrees ( minimally invasive posterior ) , respectively . Stem position was regarded as neutral in 80 % of THA through classic anterolateral and in 76 % through minimally invasive dorsal incisions . Complications occurred in 8 % ( classic anterolateral ) and 9 % ( minimally invasive posterior ) of THA patients . Surgical time , blood loss , risk of malpositioned implants , or complications were not increased for THA patients operated through minimally invasive posterior incisions compared to those operated via classic anterolateral approaches
