Epidemiology of acetabular fractures in Qatar.

OBJECTIVES: This study aimed to review the epidemiological aspects of acetabular fractures treated at Hamad Medical Corporation in Qatar. The study is the first orthopaedic trauma epidemiological study in Qatar and will provide a platform to advance high-level clinical research.

METHODS: We obtained data for 103 patients who presented to our level I trauma centre from 2008 to 2010 with a diagnosis of acetabular fracture. Age, sex, the cause of injury, fracture classification, mode of treatment, associated nerve injuries, and other complications were analyzed.

RESULTS: The incidence of acetabular fracture was 2/100,000/year. Males (93.2%) predominated. The mean age at injury time was 36 years, and the most common cause of injury was motor vehicle collisions (49.5%). Injuries were mostly primary acetabular fractures (73.6%) in comparison to (26.4%) for associated fractures. Posterior wall fractures were the most common pattern (25.2%). Associated posterior hip dislocation occurred in 21.3% of cases. Data revealed a lower incidence of post-traumatic sciatic nerve palsy (7%) that was present at the time of injury. There were no cases of reported mortality.

CONCLUSION: Acetabular fractures are uncommon injuries with motor vehicle collision being the most common cause of injury. Posterior wall fracture was the most frequent pattern, and most of the patients were males. The incidence of post-traumatic sciatic nerve palsy and the proportion of injured women were lower than those reported in literature. Well-trained surgeons and specialized centres for treating these injuries are recommended.
