Abstract

PURPOSE
The aim of this study was to determine which factors contribute to the surgical treatment outcomes of acetabular fractures. Simultaneously, we aim to report on the treatment results after our hospital was designated as the focused training center for trauma.
METHODS
We conducted a retrospective review of all patients who experienced acetabular fractures from January 1, 2014 to May 1, 2017 and visited our hospital. Patients who had associated pelvic ring fractures or were lost to the one-year follow-up were excluded; a total of 37 fractures were evaluated. We evaluated the clinical results using the scoring system of Merle d'Aubigné (MDA) and grade of Brooker for heterotopic ossification.
RESULTS
Thirty-seven patients (31 men and 6 women) were identified. The mean injury severity score (ISS) was 8.7, with 32.4% of patients having a score >15. The average blood transfusion in the first 24 hours was 0.54 pints. Falling was the most common injury mechanism (32.4%). Chest injury was the most common associated injury (16.2%), followed by head injury (13.5%). The posterior wall and both column fracture were the most common (37.8%) fracture patterns. Excellent and good clinical grades of MDA included 28 patients (75.6%) and fair and poor grades included nine (24.3%), respectively. Four patients were diagnosed with a post-operative infection (10.8%); one out of four patients who had co-morbidity died (2.7%), and another patient underwent a replacement surgery (2.7%). Multivariate analysis showed that age and operation time were associated with MDA. In addition, operation time and ISS were significant co-factors of the Brooker grade.
CONCLUSIONS
Korea University Guro Hospital showed similar treatment results of acetabular fractures compared to other publications. The age and operation time were co-factors of the clinical outcome of this fracture. Additionally, increased operation time and injury severity score were suggested to increase the Brooker grade.
