The ankle fracture with diastasis of distal tibiofibular jointis caused by an axial loading force with concomitant external rotation or other force. Many surgeons have treated this injuries by rigid fixation medial and lateral malleoli with syndesmotic fixation. But recently, syndesmotic fixation is not required to maintain the syndesmotic fixation on ankle fracture. seventy-five patients of ankle fracture with syndesmotic injury treated at Korea veterans Hospital from Jan. 1990 to Dec. 1996 were analysed in clinical and radiological aspect. The syndesmotic fixation was not necessary if the both medial and lateral injury was rigidly stabilized by fixation or ligament repair.
