The radiograph and CT scans show a posterior wall acetabular fracture with an associated femoral head fracture. As is the case in most of these injuries, the femoral head fracture is located on the anterior aspect of the femoral head. Surgical dislocation with a trochanteric flip osteotomy as described by Solberg and associates and Henle and associates allows for exposure and treatment of the posterior wall fracture as well as surgical dislocation for treatment of the femoral head fracture. A Smith-Peterson approach or Watson-Jones approach would allow for anterior exposure and may help to address the femoral head fracture, but not the posterior wall fracture. A Kocher-Langenbach approach would allow exposure of the posterior wall fracture, but not the femoral head fracture. An extensile iliofemoral approach is unnecessary for this injury pattern.
