Salter-Harris type II proximal humerus injuries: our experience with a new external fixator.

Proximal humeral fractures in the pediatric population are commonly treated conservatively. When there is an indication for surgery, percutaneous pinning is considered to be the elective choice. We report our experience with a new external fixator that reduces the risk of pin migration and permits an early rehabilitation. The range of motion was completely restored in all patients and no pain or discomfort was detected at follow-up. According to the literature, a small varus malunion at the first x-ray control can be tolerated in the pediatric population because of the remodeling ability of the bone. We conclude that this system provides a good stability and healing of Salter-Harris type II proximal humerus injuries.
