Though avulsion fracture of the fibular head rarely occurs, it frequently associates with lateral compartment injury of the knee which resulls in lateral instability. Some authors preferred to internally fixing avulsion fracture of the fibular head to prevent and restore lateral instability of the knee. Our purpose was to suggest that lateral instability of the knee be restored by internal fixation of the fibular head in these cases. We reviewed 6 cases of avulsion fracture of the fibular head associated with lateral instability of the knee which were treated surgically from January, 1993 to December, 1994 with average 2-year-over follow-up. We evaluated each cases using the Knee Ligament Standard Evaluation Form proposed by International Knee Documentation Committee. The results were as follows. The average displacement of the fibular head was 8.4mm. The activity level and overall grade were A(normal) in 4 cases, B(nearly normal) in 1 case, D(severe abnormal) in 1 case. Lateral instability of the knee was satisfactorily restored by internal fixation of the fibular head and repair of ligamentous injuries in cases of avulsion fracture of the fibular head associated with lateral instability of the knee.

The injuries of ankle in children occur mostly at the bony structure rather than ligamentous one, and some injuries of the growth plate may result in the arrest of entire growth an these may result to leg length discrepancy or deformity. Accurate treatment under the knowledge of injury mechanism is very important. We have reviewed 30 cases of childrens ankle fracture treated our clinics from Jan. 1987 to Dec. 1990.
The results are as follows; 1. Traffic accident was most common cause of injury (50.0%).
2. According to Dias & Tachdjian classification, Supination-Invertion type was most common (11 cases).
3. The treatments performed were closed reduction & cast immobilization for 11 cases (36.7%), closed reduction & percutaneous pinning for 3 cases (10.0%), and open reduction & internal fixation for 16 cases(53.3%).
4. Among open reduction & internal fixation group, only 1 case(pronation-eversion-external rotation type) show angular deformaity.
5. For the prevention of complications, accurate reduction and adequate fixation was desired.
