[Rupture of the distal tibiofibular syndesmosis without ankle fracture]

Rupture of the distal tibiofibular syndesmosis without fracture of the fibula may be a rare event, but in the presence of certain clinical signs, it should be investigated (pain and haematoma above the syndesmosis, pain at eversion and dorsal flexion, history of dislocation of the joint). The diagnostic procedure of choice is the arthrography of the ankle-joint. A so-called isolated posterior tibial fragment may lead to the diagnosis of a complex ligamentous injury.
