Medial Swivel Peritalar Fracture Dislocation: A Case Report

Abstract

A medial swivel peritalar fracture-dislocation is a rare and disabling foot injury. The terminology describes a peritalar dislocation as the direction of peritalar foot displacement. Medial dislocation is the most frequent type. A rare variant involves talonavicular joint dislocation, subtalar joint fracture-dislocation, and calcaneocuboid fracture-dislocation. The clinical position of the foot resembles an equinovarus deformity. A computed tomography (CT) scan is necessary to obtain a diagnosis and formulate a surgical plan. A medial swivel peritalar fracture-dislocation is a challenging injury, and because there have been few reported cases in the literature, an optimal treatment protocol has not yet been established. We present a case of an unusual fracture-dislocation pattern of the hind and midfoot causing a complex talonavicular fracturedislocation, subtalar fracture dislocation, and calcaneocuboid fracture-dislocation. The injury was successfully treated with open reduction and internal fixation.

A Rare Case of Fractured Posterior Facet of the Talus in Association With Open Medial Subtalar Dislocation

“…Traction and eversion is used to reduce a medial subtalar dislocation, and, on the other hand, traction with lateral rotation of foot is needed to reduce swivel. Possible causes of obstruction to reduction can be advocated to be interposition of the tibialis posterior tendon or impacted fractures of the talus or navicular [ 9 , 10 ].…”
