Variation in Treatment of Displaced Geriatric Acetabular Fractures Among 15 Level-I Trauma Centers

OBJECTIVES:To document the initial treatment of displaced acetabular fractures among older adults across multiple trauma centers and to investigate the factors that influence the decision to operate and the choice of operative procedure [open reduction internal fixation (ORIF) vs. total hip arthroplasty (THA)]. DESIGN:Retrospective observational study. SETTING:Fifteen US level-I trauma centers participating in the Major Extremity Trauma Research Consortium. PATIENTS/PARTICIPANTS:Overall, 269 patients aged 60 years or older admitted for the treatment of a displaced acetabular fracture. INTERVENTION:None. MAIN OUTCOME MEASUREMENTS:Treatment. RESULTS:Sixty percent of fractures (n = 162) were treated operatively. Younger age (
