Abstract:
Surgical treatment of proximal humeral nonunions and malunions are technically challenging. Osteosynthesis with bone grafting for the treatment of nonunions is indicated in young, active patients with adequate bone stock in the proximal fragment and preservation of the glenohumeral articular surfaces. Corrective osteotomy may be a reasonable option for proximal humeral malunions in young patients without evidence of degenerative joint disease. Arthroplasty for proximal humerus nonunions and malunions has a guarded outcome because of limitations in shoulder motion, but pain relief is more consistently improved upon.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
