Bimalleolar fractures of the ankle may cause a marked disturbance in daily life if local instability, pain and motor disturbance occur after treatment. We have treated this disease according to the following therapeutic plan.1. The ankle is immobilized in cope with its local instability with importance attached to anatomical reduction, particularly accurate reduction of the lateral malleolus.2. For the prevention of local contracture, traction of the calcaneus is positively carried out prior to reduction and immobilization.We recently treated 30 cases of Bimalleolar fractures of the ankle according to the above mentioned therapeutic plan at our department and reviewed open or closed treatment and in the lateral malleolus internal fixation of using plate or of others' instruments.The results were poor in many of the patients in whom reduction of lateral malleolus was inadequate. Displacements of lateral malleolus whether longitudinal or lateral occurred, in five cases of seven of closed treatment and no fixation, in five cases of fourteen of using Kürschner wire or Rash pin, and in no case of using plate.
