[Subtalar dislocation].

Subtalar dislocations represent uncommon injuries of the foot. Leitner [7] described the relationship between medial and lateral dislocations as 6:1. The mechanism is a trauma in plantar flexion/supination of the forefoot with a fixed hindfoot.Immediate reduction, which can usually be performed as a closed reduction is the aim of the treatment. The reduction should be performed under anesthesia in the operating room (OR) and under OR conditions in case the closed reduction shows no success. Subsequently, x-rays and CT scans should be performed in two planes in order to rule out concomitant injuries at the processus posterior tali and the talar head, as bony fragments can necessitate an operative intervention in the case of an interposition of the articulation.In terms of aftercare an immobilization of 6 weeks with a lower leg cast is suggested in the literature. In the presented case an early functional therapy with 2 weeks cast and 4 weeks with a therapy boot could achieve good clinical results.
