Operative treatment of hip dislocation combined with acetabular fractures

Abstract

Objective To evaluate the cLinical outcome and influencing factors of open reduction and internal fixation in treatment of hip dislocation combined with acetabular fractures. Methods A retrospective analysis was performed on 51 patients with hip dislocation combined with twetabular frac-tures, who were treated with open reduction and internal fixation under general anesthesia in the emergen-cy department on admission. Of all, 41 patients were treated with open reduction and plate/screw internal fixation, for which the reduction result was evaluated by postoperative X-rays and follow up X-rays accord-ing to Matta's criteria and the functional outcome by Merle d' Aubigne's criteria. Results Of 41 pa-tients, 33 were followed up for 1-7 years (mean 3.1 years). X-ray evaluation showed anatomic reduction in 27 patients (82%), imperfect reduction in five (15%) and poor reduction in one (3%). The clini-cal outcome at the time of final follow-up was graded as excellent in 18 patients (55%), good in 8 (24%), mederate in 3 (9%) and peor in4 (12%), with total excellence rate of 79%. Conclusion Prompt reduction of hip dislocation, precise reduction of the acetabular fracture and decrease of periopera-tive comphcations are key to excellent clinical outcome.
