Osteonecrosis of the talus after talonavicular arthrodesis: a case report and review of the literature.

Avascular necrosis of the talus is a well-documented complication following fractures, although less is known about this complication following reconstructive foot and ankle surgery. Knowledge of the blood supply of the talus is necessary for surgical dissection of the talus, especially when the approach traverses the sinus tarsi. In this article, we describe a rare case of avascular necrosis of the talus after talonavicular arthrodesis, using a medial surgical approach.
