PURPOSE
We report a treatment result and the pros-cons of the flexible intramedullary nailing for femoral shaft fractures in children between the ages of 4 and 11 years.
MATERIALS AND METHODS
During the recent three years, 28 femoral shaft fractures in 27 consecutive pediatric patients were treated with flexible intramedullary nailing. We retrospectively reviewed their clinical and radiological records, followed-up for at least one year, in respects to the recovery of knee joint motion; time of weight bearing; time of fracture union; period of admission and rehabilitation; angular deformity and leg length discrepancy; and other complications.
RESULTS
In all children, the knee joint motion was rapidly recovered to near normal range within 2~4 weeks. Partial weight bearing with wearing functional brace was possible within 2~4 weeks, while full weight bearing without brace was started until 6~12 (average 8.4) weeks after the nailing. In the last follow-up radiographs, five cases (18%) showed an angular deformity in any direction of more than 5 degrees. Two children represented leg length discrepancy of more than 1 cm. Other complications were one fixation failure, and one deep soft tissue infection at the entry point of the nail.
CONCLUSION
We strongly recommend the flexible intramedullary nailing in this injury because the fixation is strong enough to permit early knee motion and weight bearing in orthosis, the fracture healing was so rapid without any case of delayed or nonunion, and the incidences of residual angular deformity and leg length discrepancy were significantly less than the nonoperative treatment.

PURPOSE
To evaluation of usefulness of low-intensity ultrasound for nonunion and delayed union.
MATERIALS AND METHODS
For 5 months, we treated 7 delayed union and 8 nonunion using low-intensity ultrasound. After 5 months, in checked X-ray AP and Lateral view, when cortical bridge formation was done, we through union.
RESULTS
In 7 delayed union, 5 cases-2 femur, tibia, humerus, radius were healed. In 8 nonunion, 3 femur nonunion were healed. Union rate was 71% in delayed union 37.5% in nonunion.
CONCLUSION
we thought that the low-intensity ultrasound has capacity of induction of union and was considered as the method of treatment for delayed union.
