Fracture dislocation of the talus combined with pilon or bimalleolar fracture: a report of two cases

Abstract

Talar fractures are uncommon and talar body fracture dislocations are still rare. Simultaneous fractures of the ankle and the talar body are rare and the reported incidence in the literature is fewer than 1% of the ankle fractures. We present two cases of patients, who sustained a simultaneous fracture dislocation of talar body with fracture of medial malleolus and/or tibial pilon. The patients were treated with open reduction and internal fixation of talus through the malleolar fracture. They were evaluated at 1 year (case 1) and 8 years (case 2) of follow-up. The prognosis after this fracture dislocation is poor because of the very high risk of avascular necrosis and arthritis, even after anatomic reduction.
