Magnetic resonance imaging, computed tomography, and radiographic correlation of nonunion of the posteromedial tubercle of the talus: a case report.

Fracture of the posteromedial tubercle of the talus is an uncommon injury that is often missed on plain radiographs. In the present report, we describe the case of an adult male with a chronic nonunited fracture of the medial tubercle of the posterior process of the talus after having undergone clinical and radiographic evaluation in a community hospital emergency department. A review of the computed tomographic, magnetic resonance imaging, and plain film radiographic findings associated with nonunion of the posteromedial tubercle of the talus is also presented.
