Treatment and especially successful treatment of severe rotator cuff tears has been a challenge for many years. This is especially true when the patient also has severe shoulder joint pain.
A new shoulder implant is being used and studied for this kind of problem. It’s called the Reverse Shoulder Prosthesis (RSP). It has a ball and socket design that helps restore shoulder function and relieves pain in patients with a rotator cuff-deficient shoulder.
It does this by changing the way the soft tissues pull on the shoulder. Instead of pulling the humerus (upper arm) in towards the scapula (shoulder blade), the force is directed through the center of the humerus.
Changing the direction of the force of the rotator cuff on the shoulder joint creates stability in the joint. Instead of an upward movement of the humeral head with respect toward the socket in the scapula and a loss of joint space, the RSP resists the pull of the muscles. The design is perfect for patients with a deficient rotator cuff that can’t be repaired in a shoulder joint with severe athritis.
