Posterior Wall Acetabular Fractures: Current Concepts Review

Introduction Posterior wall fractures account for up to 30% of all acetabular fractures and are the most common subtype [1, 2]. Often associated with a concomitant hip dislocation, they are frequently the result of high energy mechanisms such as motor vehicle accidents. An axial load applied through the femur, as often seen in dashboard injuries, can lead to impaction of the femoral head on the posterior surface of the acetabulum [1]. Indications for surgical management rely on the stability of the hip joint, which can be determined intraoperatively using a dynamic fluoroscopic examination under anesthesia. For those treated with open reduction and internal fixation, an accurate and congruent reduction is crucial to a successful outcome [3].
