Astragalo-Scapho Calcaneal Dislocation and Literature Review

Abstract

Introduction: The subtalar dislocations are rare, this is described as a dislocation of the talo-calcaneal and talo-navicular joints but the tibio-talar joint is intact. The diagnosis is easy and done with x-ray: antéro-posterior and lateral view. A emergency reduction is necessary In a few cases, you need a surgical approach if the dislocation is irreducible or no stable after reduction. Case Report: A man aged of 19 years, felt in climbing, with a forced varus. In emergency room, the clinical exam showed a deformation and the x-ray: a talo-naviculo-calcaneal dislocation. A reduction is done in the operative room, the testing a showed a stable ankle so we stabilized with a posterior splint. During the post-operative consultation: the control x-ray showed a good reduction and the CT: a minimal osteo-cartilagny tearing. The sport is authorized after three month. Conclusion: The talo-naviculo-calcaneal dislocation is rare following a plantar flexion and inversion. A diagnosis is quickly and easily done and the reduction is done in the operative room under general anesthesia. A cast is applied during some weeks before starting the physiotherapy. A surgical treatment is done in a few rare: irreducible – instable – open dislocation.
