[Lower leg fractures with rupture of the syndesmosis].

In tibia and fibula fractures the classification of Weber for malleolar fractures is not valuable. Very rare are fractures of the lower leg (tibia and fibula) together with a ruptured syndesmosis. But it exists, the surgeon has to know it, if the patient complains in addition of pain in the region of the lateral malleolus. One typical case is reported. In 4760 documented tibia fractures we had 39 cases with ruptures of ligaments. Lesions of the syndesmosis were seen in 11 cases and fractures of the Volkmann triangle in 4 cases.
