摘要

Introduction Up to 25% of acetabular fractures have poor functional outcomes in short-term follow-up. The aim of our study is to analyze predictors related to poor outcome in surgically treated acetabular fractures. Damage to the femoral head cartilage and poor fracture reduction has been reported as predictors to total hip arthroplasty (THA). Material and methods retrospective study of 207 consecutive patients with acetabular fractures, over a fourteen-year period. Demographic data, fracture pattern according to AO/OTA, complications related to surgery and predictor variables were analyzed. Results Analyzing predictor variables, we observed seagull sign, femoral head dislocation, femoral osteochondral damage, acetabular marginal impaction, poor acetabular roof congruency after surgery (p < 0.001) and postoperative fracture congruence (>3mm) (p < 0.023) statistically related to the need of a THA during follow-up. Age (p = 0,98), Sex(p = 0,27), AO-OTA classification (p = 0,10), type of dislocation (p = 0,25), surgical approach (p = 0,57), time to surgery (p = 0,66) and posterior wall involvement (p = 0,06) were not related to THA. Most frequent complication was nerve injury, affecting 22 patients (20.18%). Only seventeen patients (15.6%) needed a THA at an average time of 6 years after initial open reduction and internal fixation. Conclusion Femoral head damage and dislocation, fracture reduction, and seagull sign were the strongest predictors related to THA after surgical treatment of acetabular fractures.
