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()

INTRODUCTION AND IMPORTANCE: Ankle 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 PRESENTATION: The 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 DISCUSSION: The short, medium and long term clinical and radiological results are excellent with no evidence of ankle instability or osteoarthritis. CONCLUSION: Ankle 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.
