90° Rotation of talus in a closed medial subtalar dislocation: A unique case

Abstract

Subtalar dislocations are rare and account for about 1% of all dislocations. Standard management is by prompt reduction by closed means, which if unsuccessful, should be followed by open reduction. We present a case report of a closed medial subtalar dislocation in which the talus is internally rotated by 90° and the talar dome formed a pseudoarticulation with the medial malleolus following unsuccessful attempts at closed manipulation and reduction. The patient underwent successful open reduction and fixation and subsequently recovered completely with an American Orthopaedic Foot and Ankle Society hindfoot score of 100 at 5 years after injury. To the best of our knowledge, this is the first case report of a closed talus rotation.
