Talonavicular dislocation with associated cuboid fracture following low-energy trauma.

Isolated talonavicular dislocations are uncommon injuries, usually occurring as a result of high-energy trauma. As a result extensive disruption of the midfoot ligamentous structures commonly occur with these injuries, often resulting in a poor outcome. Due to its rarity these injuries remain poorly understood, and several opinions exist on the probable mechanisms of injury and the optimal treatment.
