Subtalar Dislocation

The above images demonstrate a medial subtalar dislocation (the foot and calcaneus are medially displaced). The mechanism of this injury is usually due to a fall from a height or a severe twisting injury as in the basketball player above who landed on an inverted foot.

Prompt reduction of this injury is necessary because associated damage to the tibial nerve, and posterior tibial artery and veins may be present and long term sequelae of neurovascular injury should be avoided.
