Post-traumatic nonunion of a clavicle fracture in a 9-year-old child.

Clavicular fractures account for around 15% of fractures in children. Although nonunion is a recognized complication in adults, post-traumatic nonunion of the clavicle in children is extremely rare. To the best of our knowledge, post-traumatic nonunion of the clavicle in a child following repeated clavicular fracture has not yet been published in the English literature. Here, we report a case of a 9-year-old boy who presented with post-traumatic nonunion of his right clavicle following his third fracture after radiologically documented healing of the first two fractures. He underwent open reduction and internal fixation, supplemented with ipsilateral iliac crest bone graft, with resultant healing on follow-up radiographs.
