ORIF Surgery for Proximal Humerus Fracture
Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position (displaced).
If the fragments are shifted out of position, surgery is usually required. The surgical procedure will repair the break in the proximal end of the humerus. ORIF stands for Open Reduction Internal Fixation. During this procedure, an incision will be made and a metal plate will be attached to the humerus to hold the bone in place while it heals.
