BackgroundThis study aims to evaluate the radiological and clinical mid-term results of the patients with displaced acetabular fractures surgically treated with open reduction and internal fixation using an anterior intra-pelvic approach (AIP).MethodsIn this study, we retrospectively reviewed 12 patients with displaced acetabular fractures treated surgically via the AIP approach. Patients were analyzed for Letournel's acetabular fracture classification, associated injuries, time to surgery, additional surgical procedures needed, perioperative and postoperative complications, radiologic and functional results.ResultsOf the 12 patients, the male/female ratio was 1/2; the mean age was 40.5±16.2 (16-64) years. The mean follow-up time was 59.8±32.2 (12-124) months. Seven patients had both column fractures, three patients had anterior column + posterior hemitransverse fractures, one patient had transverse + posterior wall and one patient had anterior column fracture. The mean time to surgery was 6.6±4.4 (2-16) days. The mean intraoperative blood transfusion was 830 (300-2000) ml. Intra-operative and post-operative complications were noted in eight patients. The mean Merle d'Aubigné and Postel score was 14.5±2.7 (10-18). Six patients with an anatomical reduction of the fracture showed excellent/good functional and radiologic outcomes. Three patients with a non-anatomic reduction developed post-traumatic arthrosis that was treated with total hip arthroplasty.ConclusionAIP approach provides a satisfactory exposure for the surgical treatment of displaced anterior wall/column and both column acetabular fractures. Clinical outcome is directly related to the reduction quality. Patients with poor reduction are most likely to develop mid-term complications, such as hip joint arthrosis.
