[Associated fracture of the posteromedial tubercle and the lateral process of the talus: a case report. Contribution of computed tomography].
OBJECTIVE
Fracture of lateral process of the talus is an uncommon injury, fracture of the posteromedial tubercle of the talus is quite rare, and association of the two lesions is not reported previously. We report a case of an associated fracture of posteromedial tubercle an lateral process of the talus.


METHODS
The mechanism of injury was forced ankle dorsiflexion and pronation, this mechanism was responsible of an avulsion of the posteromedial tubercle by the postero talotibial ligament and a fracture of lateral process by compression between the lateral malleolus and the calcaneus.


RESULTS
Conventional radiographs permitted the diagnosis of the lateral process fracture but the fracture of the posteromedial tubercle was showed only on CT scans.


CONCLUSIONS
The fracture of the posteromedial tubercle was treated by internal fixation, through a posteromedial approach. At 12 months follow-up the patient was able to walk without pain and radiographic result was excellent (no avascular necrosis of the tubercle and no Arthrosis of subtalar joint).
