Irreducible Anterior Subluxation of the Ankle Joint Caused by Os Trigonum and Transverse Ligament: A Case Report

Abstract

Ankle joint is a stable mortise structure, therefore pure ankle dislocation without ankle fracture is rare. Several adjacent anatomical structures have been reported as a cause of irreducible ankle dislocation. Author report a case of successful treatment of irreducible anterior subluxation of the ankle joint due to os trigonum and transverse ligament by closed reduction under anesthesia, and a review of the literature as well.
