The majority of proximal humeral fractures can be treated nonoperatively with good clinical outcomes, owing to the tremendous remodeling potential of the proximal humerus. However, in older children with less growth remaining, severely displaced fractures may be treated operatively to restore anatomic alignment and maximize shoulder motion.Surgical treatment is often advocated for unstable or severely displaced proximal humerus fractures in older children. The purpose of this study is to assess early radiographic results and complications of percutaneous pinning (PP) used to treat these fractures.
