Abstract： INTRODUCTIONDistal tibiofibular syndesmosis injuries are usually associated with ankle fractures,especially common in Denis B and C fractures.[1] Syndesmosis is essential for stability of the ankle mortise that is required for weight transmission and walking.The syndesmosis consists of the anteroinferior tibiofibular ligament,posteroinferior tibiofibular ligament,inferior transverse tibiofibular ligament,and interosseous membrane.Internal fixations of the syndesmosis were recommended by most authors to repair the associated ruptured ligaments,[2] which bring about the adverse consequences of limiting the physiological micromovement of the tibiofibular joint to some extent.
