[Reverse shoulder arthroplasty for fracture sequelae].

Posttraumatic fracture sequelae of the proximal humerus represent an extremely heterogeneous pathology. In severe cases they are often associated with marked soft tissue scarring, osseous defects and insufficiency of the rotator cuff, resulting in a static instability of the humeral head. The aim of this article is to demonstrate the possibilities and early results of reverse shoulder arthroplasty for the operative management of this complex injury pattern.
