The childrens ankle injury is different from that of adults in terms of the possibilities of injury to growth plate and influence to growth. Therefore accurate reduction under the knowledge of prognosis of the injured growth plate is very important. Many authors agree that the prognosls of injured growth plate is dependent on the injury type, the age of the patient at the onset of injuries, the method and accuracy of reduction. and whether the injuries open or closed. We treated 45 cases of children ankle injuries from August 1983 to June 1991 and evaluated the cases of eight children who had a injury loading to complication. Most of them had had a Salter-Harris type II or type III injury of the distal end of the tibia. Initially all the cases were treated with accurate reduction of thr physis as much as possible, but six of them developed growth disturbance including physeal arrest, temporary cessation of the growth and growth retardation, while two did growth stimulation.
