Internal fixation is commonly used to treat fractures in the hip. However, failure of proximal femoral fracture fixation is common and treated with total hip replacement (THR). The aim of this study is to present our midterm results of dual mobility (DM) THR for failed internal fixation of proximal femur fractures. Between 2010 and 2015, a total of 28 cases of failed internal fixation for hip fractures were treated through DM total hip arthroplasty. Two patients died during the early postoperative period due to medical complications. The average follow-up was 3.4 years. We had one patient with superficial surgical site infection which was managed by local wound debridement and dressings. The average Harris hip score was 85. DM THR is the procedure of choice for revising failed internal fixation for hip fractures in our patients with good clinical outcome.
