DJO Surgical Reverse Shoulder Prosthesis (RSP™)

Abstract

Due to shortcomings of the reverse shoulder prosthetics of the time, the DJO Reverse™ Shoulder Prosthesis (RSP) was designed to create a more anatomic alignment of the shoulder and reduce the complications associated with the Grammont design. The main features of the prosthesis are its lateral center of rotation and its central lag screw, providing a more anatomic center of rotation and a more compressive force, respectively. The humeral component offers both cemented and press-fit options that provide a better mechanical environment for the rotator cuff to assist with shoulder motion. Outcomes for the RSP show consistent postoperative improvement as well as low complication rates in the modern design. The use of the RSP with proper surgical technique can result in predictably good outcomes.
