A 66-year-old female who has acetabular protrusio and end-stage osteoarthritis of the right hip undergoes total hip arthroplasty through the ABMSparing approach. According to the authors, this approach avoids the complications of wound healing that can occur with an approach that crosses the hip flexion crease, as well as avoids cutting muscle.
Numerous surgical approaches for total hip arthroplasty (THA) have been described. We have pursued development of an anterior-based muscle-sparing (ABMSparing) approach, with the goal of finding an exposure method that has a low incidence of complications and a short learning curve and that can be extensile if needed. Our approach provides exposure through an intramuscular plane, similar to the direct anterior approach (DA).
