Reverse® Shoulder Prosthesis (RSP®) by DJO Surgical
Center of Rotation
The Reverse Shoulder Prosthesis (RSP®) was the first reverse shoulder design to successfully incorporate a center of rotation (COR) lateral to the glenoid.
Patients presenting with an irreparable, rotator cuff deficient shoulder joint with severe arthropathy typically show evidence of an upward displacement of the humeral head with respect to the glenoid and a loss of glenohumeral joint space. Unfortunately, the functional outcomes using conventional surgical methods are severely limited and typically fail.
The Reverse® Shoulder Prosthesis is a semiconstrained design concept that reverses the shoulder anatomy by lateralizing the shoulder joint to effectively resist the superior pull of the deltoid muscle and optimize soft tissue balancing.
