Post-traumatic Radioulnar Synostosis in Distal Forearm Fractures in Children: A Report of 2 Cases

Cases: Two pediatric cases of post-traumatic distal radioulnar synostosis are reported, accompanied by a literature review summarizing evidence on the management of these conditions. Radioulnar synostosis is a rare complication of distal forearm fractures, which impairs upper-extremity function. The numerous surgical procedures that have been described to treat this condition in adults typically involve synostosis resection and an interposition graft to reduce recurrence. The optimal treatment in children has not been established. Conclusions: Post-traumatic radioulnar synostoses are rare conditions in pediatric patients who can be successfully treated with surgical excision of the synostoses and without the use of interposition grafting.
