Abstract

PURPOSE
The aim of this study was to analyze the factors affecting the outcomes after surgical treatment of acetabular fractures.
MATERIALS AND METHODS
Between January 2000 and December 2012, 106 patients with acetabular fractures were treated with open reduction and internal fixation. We performed a retrospective cohort study to analyze the factors which may influence a patient's prognosis after surgical treatment of an acetabular fracture. The factors examined included age, femoral head injury, fracture type, dislocation, initial displacement, delay to injury-related surgery (in days), and quality of reduction. Additionally, we investigated clinical and radiological outcomes, as well as the development of osteoarthritis.
RESULTS
Patients included 85 males (80.2%) and 21 females (18.8%) with a mean age of 50.4 (17-78) years. The mean follow-up period was 2.6 (1-10) years. In a univariable regression analysis, quality of reduction, age, and initial displacement were significantly associated with radiological and clinical outcomes. In a multivariable regression analysis, quality of reduction (P<0.001) and initial displacement (P=0.001) were found to be factors predictive of clinical and radiological outcomes. Additionally, the quality of reduction (P=0.005) was found to be predictive of osteoarthritis development.
CONCLUSION
Study results indicated that the quality of reduction was the most important factor influencing the prognosis of patients with acetabular fractures.
