Case report: A rare case of pure tibio-talar dislocation without malleolar clamp fracture in a young athlete: Long-term functional results and recent reviews of the literature.

Abstract

Introduction and importanceAnkle dislocation without fracture is an extremely rare injury, requires high-energy trauma, up to 1995, only 73 cases were reported in the literature and 154 cases up to 2017. It is therefore a post-traumatic ankle disease growing in parallel with the increase in road-traffic accidents requiring the study of incriminated factors such as hypoplasia of the medial malleolus.Case presentationThe authors report the case of a young patient, a football player, who presented with a pure, closed dislocation of his ankle following a road-traffic accident. Management consisted of immediate reduction, followed by immobilization in plaster for 1 month,Clinical discussionThe short, medium and long term clinical and radiological results are excellent with no evidence of ankle instability or osteoarthritis.ConclusionAnkle dislocation without associated fracture is an extremely rare injury. The posteromedial dislocation represents the most described variety in the literature. Early management, short-term immobilization, adapted and early rehabilitation seem to be associated with good long-term functional results.
