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.
全髋关节置换术（THA）的微创手术（MIS）在骨科界引发了争议，包括关于假体置入的可靠性和可重复性的争论。我们通过比较67例两切口MIS-THA和28例标准THA术后的X线片，对一位外科医生的1年经验进行了回顾，比较了髋臼倾斜度、髋臼前倾角和股骨干角。MIS-THA和标准THA的髋臼倾斜度/前倾角分别平均为42.2度/16.5度和38.7度/15.5度。MIS-THA和标准THA入路的股骨角分别平均内翻0.007度和0.411度。两切口MIS-THA与标准直接外侧入路THA的假体位置的影像学评估显示无显著差异。两种技术均能将假体置于可接受的位置。
