Talar body fractures.

Fractures to the body of the talus include a wide array of injuries, varying from relatively minor posterior tuberosity fractures to devastating comminuted body fractures. Fracture types include osteochondral fractures, sagittal transverse or coronal whole-body fractures, posterior tubercle fractures, lateral process fractures, and crush injuries. Treatment varies from excision of small fragments, such as arthroscopic treatment of osteochondral injuries, to open reduction and internal fixation of body fractures, usually by a medial malleolar osteotomy. Prognosis logically correlates with the magnitude of the injury with whole-body fractures, especially crush injuries, having the worst prognosis. Talar body fractures, similar to talar neck fractures, also can be complicated by subtalar arthritis, ankle arthritis, malunion, and avascular necrosis.
