Abstract

The reverse shoulder prosthesis reverses the relationship between the scapular and humeral component, resulting in a mechanical advantage as the deltoid muscle is able to compensate for the rotator cuff deficiency. Based on this mechanical advantage, the reverse shoulder prosthesis has become an accepted alternative for the treatment of complex proximal humeral fractures. The purpose of this article is to discuss technical considerations related to stability in the use of the reverse shoulder prosthesis in acute shoulder fractures, based on clinical experience.
