Posttraumatic pseudarthrosis of the clavicle in an 8-year-old girl.

We describe an 8-year-old girl who developed a posttraumatic pseudarthrosis of the right clavicle. Despite the great periosteal regenerative potential in children, the fracture did not heal at 12 months with a classic conservative treatment. As a result of pain and functional limitations, surgical treatment was required. Excess bone of the hypertrophic nonunion was removed and an open reduction and internal fixation with a compression plate were performed. Cancellous bone chips from the iliac crest were packed into the fracture site. Good remodelling and consolidation was achieved 10 months after the operation. At that stage, the functional outcome was satisfactory.
