The rotator cuff is a group of 4 muscles which surround the shoulder joint. They are attached to the bone via tendons. These muscles and tendons help keep the shoulder in socket and help control shoulder movements. The tendons can be damaged or torn through general use, “wear and tear” or following an injury to the shoulder. Often it is the “supraspinatus” tendon at the top that becomes worn. If the tendons are damaged the shoulder can become weak and painful.

The shoulder joint is a ball (Humeral Head) and socket (Glenoid) joint. A TSR replaces the ball and socket with an artificial joint. This is called a prosthesis and there are several different types. Your consultant will select the best type for you depending on the quality and quantity of bone as well as the strength of the muscles around your shoulder joint. In certain cases a bespoke prosthesis may need to be designed and made for you.

A shoulder plaster spica is a plaster cast that is made to fit around your chest, shoulder and arm. This is to keep the limb immobilised, supported and protect the surgery. It is usually made before your surgery and put on in theatre after your operation.
