Treatment of Bimalleolar or Trimalleolar Ankle Fractures with Rigid Internal Fixation
並列摘要
Thirty-six patients with a displaced, unstable bimalleolar and trimalleolar ankle fracture treated by open reduction and rigid internal fixation were retrospectively analyzed. All fractures were Danis-Weber type B or C. Twelve lesions were injuried by supination-external rotation; twelve, by pronation-external rotation; and twelve, by pronation-abduction. After an average follow-up of three years, 89% of the results were satisfactory. Poor results occurred in the more severely injured, and inadequately reduced ankles. Associated ipsilateral tibia bone fracture, malreduction of fibular fracture and posttraumatic arthrosis were the main factors predisposing to an unsatisfactory re-sult. The surgical outcome of Danis-Weber type C fracture was not inferior to that of Danis-Weber type B fracture. Exact restoration of fibula length and shape, and adequate reduction of syn-desmosis were-essential to achieve a stable ankle-and a good result. A contrast view of the contralateral ankle was useful as a template in difficult fractures.
