PURPOSE: To evaluate the clinical and radiological results of wire fixation for acetabular fracture and its merits. MATERIALS AND METHODS: From 1996 Jan. to 1998 Dec., 18 cases of being fixed by wire among 42 cases who being treated by surgical method were analyzed. We evaluated these cases after a mean follow up of 2.1 years. The fixation was done by wires in 11 cases, wires with plate in 3 cases and wires with screw in 4 cases. RESULTS:According to Epstein's criteria, favorable results were achieved in 15 cases(83.3%) on clinical grade and 14 cases(77.7%) on radiographic grade. CONCLUSION: The results of this study suggest that open reduction and internal fixation with wire is preferable method that can permit early ambulation, decrease postoperative complication and achieve firm fixation, comparing with open reduction and internal fixation with plate and screws, in treatment of displaced acetabular fractures.
