Abstract

Minimally invasive surgery (MIS) for total hip arthroplasty (THA) has sparked controversy in the orthopedic community, including debate regarding the reliability and reproducibility of component placement. We reviewed a single surgeon's 1-year experience by comparing postoperative radiographs of 67 MIS 2-incision THA and 28 standard THA for acetabular inclination, acetabular version, and femoral stem angulation. Acetabular inclination/version averaged 42.2°/16.5° and 38.7°/15.5° for MIS and THA, respectively. Femoral angulation averaged 0.007° varus and 0.411° varus for MIS and standard THA approaches, respectively. Radiographic assessment of component position of THA in 2-incision MIS vs a standard direct lateral approach reveals no significant differences. Components are placed in acceptable positions with both techniques.
