Entire posterior process talus fracture: a report of two cases.

The complex anatomy of the posterior process of the talus includes the medial and lateral tubercles extending from the talar body. Review of the current literature indicates that fracture of the entire posterior process of the talus is a rare injury. Two patients presented to our emergency department after motor vehicle accidents, and both were diagnosed with entire posterior process talus fractures. After evaluation of each patient, treatment of each was undertaken by means of open reduction and internal fixation via the posteromedial approach to fracture. Headless screws were used to fixate the reduced posterior tubercle in each case. Based on our experience with the patients described in this report, open reduction and internal fixation appear to be suitable methods of treatment for complete posterior process fractures of the talus.
