[Posttraumatic nonunion of the clavicle in a child: case report]

A thirteen-year-old child underwent surgery for posttraumatic nonunion of the clavicle. This complication, which is uncommon in adults and exceptional in children, occurred after three fractures of the left clavicle. The diagnosis can be retained after ruling out congenital nonunion of the clavicle. Surgery can be proposed if functional impairment persists for at least one year. For children, the preferred technique is osteosynthesis with centromedullary pinning and bone graft. While surveillance may not be necessary for a unique fracture of the clavicle, prolonged surveillance appears to be necessary in patients who sustain repeated fractures of the clavicle.
