Abstract
PURPOSE: This study examined the complications and outcomes of geriatric acetabular fractures treated with open reduction internal fixation (ORIF) and total hip arthroplasty (THA) performed via combined ilioinguinal or anterior intrapelvic (AIP) approach to acetabulum and anterior approach to the hip. METHODS: Eight patients with a fracture of the acetabulum were treated at a Level I trauma center between 2010 and 2019 with combined ORIF/THA using an ilioinguinal or AIP approach for the acetabulum and a separate anterior approach to the hip. Wound dehiscence, peri-incisional skin necrosis, surgical site infection, dislocation, fracture union, acetabular component stability, and heterotopic ossification (HO) were utilized as outcome measures. Merle d'Aubigné-Postel scores were collected for the six patients that had one-year minimum follow-up. RESULTS: The mean patient age was 77 years. Four patients had anterior wall fractures, two had associated both column fractures, and two had anterior column-posterior hemitransverse fractures. All fractures healed with stable fixation of the acetabular component by 6 months. There were no instances of skin necrosis, dislocation, infection, or re-operation. One patient had a superficial wound dehiscence that resolved with local wound care. One patient developed radiographic HO but was clinically asymptomatic. The mean Merle d'Aubigné-Postel score was 15.8 (range = 14-16). CONCLUSIONS: Our small series of geriatric patients with fracture of the acetabulum treated with combined ORIF/THA, via the ilioinguinal or AIP approach with a separate anterior approach to the hip, demonstrates satisfactory outcomes with low complications after one-year of follow-up. Further research of these challenging injuries with more patients is warranted in order to determine the subset of fracture types best treated with this method and THA survivorship.
