Fracture of the neck of the talus associated with a trimalleolar ankle fracture and ruptured tibialis posterior tendon.

A rare case of a fracture through the neck of the talus with a trimalleolar ankle fracture and ruptured tibialis posterior tendon is presented and the literature reviewed. Management consisted of open-reduction internal fixation of the fractures and repair of the tibialis posterior tendon. At 40 months after injury, the patient had tibiotalar range of motion at 5 degrees of dorsiflexion and 38 degrees of plantar flexion. While avascular necrosis of the talus did not occur, significant degenerative arthritis of the ankle was noted.
