O3292 SINGLE APPROACH SURGERY FOR ACETABULAR FRACTURES

Abstract

Aim: We report results of surgical treatment of acetabular fractures and highlight the importance of single approach for complex fractures. Methods: 50 acetabular fractures referred to a specialist unit between 1994 and 1999 were treated surgically with anatomic reduction and internal þxation. Mean follow up was 32.3 months (14 to 67). Patients were regularly followed up in a special pelvic clinic for documentation of Harris hip score (pain, function, movement, activity), and radiological evidence of healing, avascular necrosis or other complications. Results: 18 patients were treated with the anterior ilioinguinal approach for 11 both- column, 3 anterior column, 3 transverse fractures and 1 central dislocation. 28 patients had posterior Kocher-Langenbeck approach for 17 posterior fracture dislocations, 2 both-column, 6 posterior wall and 1 each of transverse, posterior column and Tshaped fracture. 4 needed combined anterior- posterior or extensile triradiate approach due to comminution or delayed referral. Mean hospital stay was 24.7 days and mean injury surgery interval was 10.8 days. Of the 42 transfers from other units, 7 had surgery after 3 weeks from the injury. Outcome: 47 patients were followed up. Mean Harris hip score was 82.7 (31–100) for the posterior approach group, and 78.1 (27–99) for anterior approach group.3 patients needed total hip arthroplasty for secondary arthritis. Grade3–4 Brooker ectopic bone was noted in 3 posterior and 1 anterior approaches. There was no infection or avascular necrosis. Conclusion: Single approach surgery was possible in 46 patients and had a low rate of complications. Poor outcome occurred in highly comminuted fractures or with a delay in referral. Anterior ilioinguinal approach, although demanding, was the approach of choice for both column fractures. Early referral to a specialist unit is recommended.
