Radioulnar synostosis is rare after pediatric forearm fractures. This small study details two children who underwent excision of radioulnar synostosis. The synostosis was a Type 2 that affected the nonarticular mid-third of the forearm. Both cases underwent excision of the synostotic bone after bony maturity. No interpositional material was used in the first case and a Gore-Tex vascular graft was positioned around the ulna in the second case. Both cases had an adequate restoration of forearm rotation, although the first patient lacked 45 degrees of pronation. Synostosis of the pediatric forearm is uncommon. Type 2 synostosis should be treated in a similar fashion as adults. Resection of the crossed union as soon as the bone appears to be mature leads to adequate results as documented in this small series. Extrapolation of this series to a larger population and to different types of synostosis would be helpful.
