摘要
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 degrees/16.5 degrees and 38.7 degrees/15.5 degrees for MIS and THA, respectively. Femoral angulation averaged 0.007 degrees varus and 0.411 degrees 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.
