We are reporting the results of treatment of unstable acetabular fractures, comparing operative with non-operative treatment in a small group of patients.Methods: In a retrospective study, in a teaching hospital, 20 cases of unstable acetabular fracture treated with open reduction and internal fixation were compared with 20 cases who had been treated non-surgically. The mean age was 34.5 years old (20-50 yrs old). The early clinical resuts, including complications, and also treatment costs were compared in those two groups.Results: There was no significant difference in the level of function between the two groups.There was a higher rate of heterotopic ossification and nerve injury in the operated cases, but not statistically significant. The time to fracture :::union::: was less in the non-operated cases. The hospital cost was significantly higher in the non-operative group (p < /em> Background: Acetabular fracture is a common injury, with unclear treatment outcome.
