Pure antero-superior tibio-talar dislocation without fracture in the setting of severe soft tissue injury: A case report

Abstract

Ankle dislocation is rare form of ankle injury that is usually associated with malleolar fracture. Its occurrence in the absence of any fracture is very rare. It is usually caused by high energy trauma. Several forms have been reported with the medial and posteromedial dislocation being the most frequently reported. We report a case of 28 years-old-male patient presenting with crushing injury of the leg causing a pure anterior-superior dislocation of the tibiotalar joint associated with degloving injury of the leg in the absence of any fracture. To our knowledge, this is the first case in English and French written literature to describe an anterior-superior direction of pure ankle dislocation. In this report, we review the literature for similar case, and discuss the available treatment options in such a unique association, especially in the presence of soft tissue compromise.
