The purpose of this study is to find the effective treatment method by evaluating the frequency and causes of complication in each Salter-Harris types.
The materials were 26 ankle physeal injuries treated from 1989 to 1994 with least follow-up of 12 months(ranged 12 to 62 months).
The results were as follows.
1. There were 14 boys and 12 girls with an average age of 11 years(range,3-15years) 2. According to Dias and Tachdjian classification, mechanisms of injury were pronation-eversion external rotation type in 7, supination-inversion type in 6, supination-plantar flexion type in 4, supination-external rotation type in 2, Tillaux in 3, unclassified in 4.
3. Amomg 26 cases operative treatment was done in 11 cases that include 4 cases of closed reduction & percutaneous pinning and 7 cases of open reduction & internal fixation.
4. Among 26 cases, complication occurred in 4 cases, in which 3 cases were treated by closed reduction and cast irnrnobilization only or with percutaneous pinning.
5. It is most important for prevention of complication that Salter-Harris type II, III, IV fractures were to be reduced accurately and fixed adequately.
6. Because Tillaux fracture ocurs near the age of epiphyseal closure, there were no clinically significant deformity after long term follow up.
In 3 cases of Tillaux fracture, the resluts were good.
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.
