Comparison of acetabulum posterior wall fractures and fracture dislocations: dislocation does not affect clinical and radiological outcomes

Abstract

The aim of this study was to compare radiological and clinical outcomes of posterior wall acetabulum fractures and posterior wall fracture dislocations. Data were including 52 acetabulum fractures and fracture dislocations. 26 patients (%50) had posterior acetabulum fractures and fracture dislocations who were operatively treated. Radiographic evaluations were performed before and after the operation and at the last follow up. Clinical outcome evaluation was performed at the last follow up. Clinical and radiological outcomes were evaluated including Merle D'aubigne clinical assessment score and Matta' s radiologic measurement score. Brooker classification was used to measure heterotopic ossification.Both Merle D'aubigne and Matta scores were found higher in the acetabulum posterior wall fracture group. But there wasn't significantly difference of clinical and radiological outcomes between two groups (p > 0,05). Reduction quality and Matta radiologic scores were correlated significantly in 2 groups. Posterior dislocation may not negatively affect clinical and radiologic outcomes.
