Rotator cuff tendon at the entrance of the bicipital groove. The supraspinatus is most commonly involved in a rotator cuff tear. The rotator cuff muscles are important in shoulder movements and in maintaining glenohumeral joint (shoulder joint) stability. These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint. They hold the head of the humerus in the small and shallow glenoid fossa of the scapula. The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee (glenoid fossa). During abduction of the
Rotator cuff tear large full thickness rotator cuff tears. Rehabilitation after surgery consists of three stages. First, the arm is immobilized so that the muscle can heal. Second, when appropriate, a therapist assists with passive exercises to regain range of motion. Third, the arm is gradually exercised actively, with a goal of regaining and enhancing strength. Yoshitsugu Takeda and his team have recently studied rotator cuff injuries and rehab exercises that target the supraspinatus. As mentioned earlier, the supraspinatus muscle is the muscle and tendon within the rotator cuff that is most often injured. In order to rehab the supraspinatus and combat future
