Abstract
Aim: The results of operative treatment of acetabular fractures, as well as its role in the prevention of post-traumatic osteoarthritis are presented. Methods: From 1990 to 2000, þfty patients had an open reduction and internal þxation of an acetabular fracture. Thirty-two patients were male and eighteen were female, with an average age of 37,8 years (range: 18 to 71 years). The mechanism of injury was a motor vehicle accident in most cases (84%). 22 fractures were A-type, 24 B-type and 4 C-type according to the AO classiþcation, while according to the Letournel-Judet classiþcation 21 fractures were simple and 21 complex. Osteosynthesis was achieved with either lag screws alone or with a combination of lag screws and a buttress plate. Results: Follow-up ranged from 2–10 years (average: 5,8 years). Clinical evaluation according to the Dñ Aubigne-Postel scoring system gave 20 excellent (40%), 18 good (36%), 5 fair (10%) and 7 poor (14%) results. Early postoperative complications included 5 cases of common peroneal nerve palsy and 3 cases of wound infection. Late complications included 1 case of avascular necrosis of the femoral head, 12 cases of post-traumatic osteoarthritis (24%) and 5 cases of Brooker III heterotopic ossiþcation (10%). Conclusions: Operative treatment of ace-tabular fractures although demanding bears very good results. Post-traumatic arthritis remains a common complication, even if care is taken for the anatomic reduction of the fracture.
