FERREYRA, Andrés; ALLENDE, Victoria; MASQUIJO, Julio Javier  e  ALLENDE, Guillermo José. Initial experience with surgical hip dislocation. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2012, vol.77, n.1, pp.29-38. ISSN 1852-7434.

Background: Surgical dislocation of the hip is a recently described surgical approach that allows a complete visualization of the acetabulum, and femoral head and neck. The aim of this study is to analyze the functional results and complications we had with this approach at our institution. Methods: Sixteen hips that underwent surgical hip dislocation between January 2003 and January 2010 were included. Surgery was indicated in femoroacetabular impingement (4), coxa profunda (4), slipped capital femoral epiphysis (5), synovial chondromatosis (1), chondral injury (1), and segmental osteonecrosis of the femoral head (1). We analyzed clinical and radiographic data before and after surgery. Results: Three patients required total hip replacement (THR), one because of avascular necrosis (AVN), and the remaining two because of symptom progression. Seven patients had good and excellent results, two fair, and four poor results. Three patients had major complications (AVN), while three had minor complications: painful greater trochanter (2), and loosening of the trochanter fixation (1). Six patients required additional surgery: oste-osynthesis removal 5 cases, THR 3 cases, valgus osteotomy 1 case, and greater trochanter osteosynthesis revision 1 case. Conclusions: In our initial experience, surgical dislocation of the hip has shown to be a challenging approach that requires thorough anatomical knowledge, and accurate patient selection.
