Talar neck fracture with talar head dislocation and intact ankle and subtalar joints: a case report.

The authors describe a rare case of fracture of the neck of the talus associated with talonavicular dislocation but no disruption of the ankle and subtalar joints. The fracture united after open reduction and internal fixation. The head of the talus revealed avascular necrosis but the body did not. A literature review retrieved one previous report of a similar injury, but it was open and became infected. The unique features of this injury pattern and its specific complication, isolated avascular necrosis of the talar head, are discussed.
