Arthroscopic-Assisted Bone Graft Harvest From the Proximal Humerus for Distal Third Clavicle Fracture Nonunion.

Clavicle fracture nonunion can lead to persistent pain and loss of shoulder function. Distal clavicle fractures have the greatest risk of nonunion and are often treated surgically. Bone grafting plays a vital role in the treatment of distal clavicle nonunion. Although multiple options for bone graft exist, the iliac crest has long been considered the gold standard for harvest. Despite its extensive use, multiple complications have been associated with iliac crest bone graft harvest. We advocate a surgical technique for arthroscopic bone graft harvest from the proximal humerus with open reduction and internal fixation of an ipsilateral distal clavicle nonunion.
