Traction has been known, generally, as a treatment of choice for fracture of femur in children. But, it needed some modification by age of patient, site of fracture or/and associated injury. We reviewed the 92 fractures of femur in 88 patients and analysed as following; l. Age incidence was evenly distributed from 7 months to 16 years (average, 8 years 9 months). There were 61 boys and 27 girls. Z. Most common cause was traffic accident (90%). 3. Fracture sites were 54 midshaft, 18 inter and subtrochanteric area, 9 proximal third, 8 distal third and 3 epiphyseal injury of distal femur, respectively. 4. 61 cases were treated by nonoperative method: 37, 90-90-90° traction; 15, Buck's extension; 4, Bryant traction; and 5, cast immobilization. 5. 31 cases needed operative treatment for the management of 11 inter- and subtrochanteric fracture, 9 multiple fracture, 3 head injury, 3 open fracture, and 2 epiphyseal injury. 6. 49 fractures in 45 patients were followed from 1 year to 6 years 9 months (average, 3 years 6 months). 7. There were no significant differences in the immobilization period among nonoperative methods. However, the immobilization period was shorter in the young patients treated by nonoperative method or patients treated by operative method than in the older patients treated by nonoperative method. 8. Complications were 4 limited motion of hip joint, and 8 limping. 9. Leg length discrepancy was average 1.6mm lengthening range (from 33mm shortening to 19mm lengthening) in affected side.
