Medial subtalar dislocation associated with fracture of the posterior process of the talus. A case report.

A 27 year-old man was involved in a high-energy-impact motor-vehicle accident and sustained multiple injuries including a medial subtalar fracture dislocation. The dislocation of the subtalar joint was reduced by closed means, but a large, comminuted, displaced posterior process fracture remained. Open reduction and internal fixation through a posteromedial approach with mobilization of the neurovascular bundle was used to restore congruity to the subtalar joint.
