title: Fracture of the entire posterior process of talus associated with subtalar dislocation: a case report.
abstract: This is a case report of a 52-year-old woman who sustained a medial subtalar dislocation with fracture of the posterior process of the talus in a traffic accident. After closed reduction of the subtalar dislocation, tomography demonstrated that the talus fracture involved the entire posterior process and the posterior portion of the talar body. The fracture of the talus was treated with an open reduction and miniscrew fixation. At follow-up examination 32 months later, the functional and radiographic results were graded as good. The proposed mechanism of this case was a forced plantarflexion and inversion acting simultaneously on the subtalar joint. This was different from an isolated medial subtalar dislocation, which was caused by an inversion.
