Reverse Shoulder Arthroplasty for the Treatment of Nonunions of the Surgical Neck of the Proximal Part of the Humerus (Type-3 Fracture Sequelae)

Abstract

Nonunions of the proximal part of the humerus can be treated with reverse shoulder arthroplasty. Although clinical outcomes improved significantly, we found an unacceptably high rate of dislocations associated with intraoperative resection of the tuberosities. The tuberosities and the attached rotator cuff should be preserved if possible to reduce the risk of dislocation after reverse total shoulder arthroplasty.
