Open Femoral Osteochondroplasty and Rim Trimming

The goal of femoroacetabular impingement (FAI) treatment is restoration of normal hip function by removing pathomechanic deformities. The efficacy of surgical treatment has been demonstrated for both arthroscopic and open surgery. While isolated insufficient waist of the head–neck junction ± localized acetabular overcover is the domain of arthroscopy, open surgery with hip dislocation is indicated in more global deformities, as well as when additional axial corrections and/or trochanteric advancement are necessary. Surgical dislocation of the hip is a safe approach with low risk of avascular necrosis and little morbidity; it provides complete visualization of the acetabular cavity and of the femoral head surface. When needed, it can be extended to the proximal femur. When additional periacetabular osteotomy is indicated, the first ischial cut can be executed through the approach.
