PURPOSE To determine the usefulness of flexible intramedullary fixation in pediatric forearm diaphyseal fractures. MATERIALS AND METHODS We reviewed 22 cases of forearm diaphyseal fractures treated with flexible intramedullary nail and K-wire. The radiographic assessment was based on the time to union, maintenance of reduction and angular deformity. The functional outcome was assessed with the range of motion and complications at last follow up. RESULTS Average length of follow up was 13.9 months with mean age of 10.8 years and the time to union was 5.2 weeks. There were no angular deformity and fuctional results were excellent in all cases. There were 5 cases of soft tissue irritation of nail insertion site as post operative complication which was resolved after nail removal. CONCLUSION Flexible intramedullary for pediatric forearm bone fractures is an effective and safe method which gives a good functional outcome.
