An aviator fracture is a coronal-plane fracture of the neck of the talus resulting from forced dorsiflexion of ankle. It is the second most common talar fracture, after talar dome fractures.
In 20% of cases a fracture of the medial malleolus is also present 1.
These fractures are at risk of avascular necrosis.
The name arises as it was frequently seen in aircraft crashes (presumably on landing), when as the plane comes to a sudden stop, the rudder bar is driven forcibly against the middle of the sole of the foot.
