Rotator cuff muscle is an important muscle group in the body. This muscle group is located near the shoulder. It consists of four muscles that help in holding the arm and the shoulder together at the shoulder joint.
These muscles stretch from the scapula to the humerus bone of the arm. The four rotator cuff muscles have dissimilar functions with regard to the arm and shoulder movement. These muscles are: supraspinatus, infraspinatus, teres minor, and subscapularis. They help in holding the humerus bone and preclude it from popping out of the shoulder joint.
The supraspinatus is the most important muscle of the rotator cuff. Supraspinatus muscle starts from the scapula and stretches up to the humerus and the acromion is very close to this muscle. Most of the rotator cuff tear and impingement happen with this muscle. The main function of this muscle is the abduction of the arm.
The role of the subscapularis muscle is important in the movement of the humerus and the elevation of the arm which requires depressing of the humerus head. Lateral motion of the arm is facilitated by the infraspinatus and teres minor muscles.
A rotator cuff tear is the tear of the rotator cuff tendon. Arthroscopic rotator cuff surgery is resorted to repair the torn rotator tendon as last option rehabilitation method. The surgery requires small incisions in the rotator cuff muscles to reach the rotator tendons.
These muscles can be strengthened to preclude time to come rotator cuff tear. Rotator cuff strengthening can be a part of recovery of rotator cuff surgery patients. They are strengthened moderately under the master advice of certified and trained physiotherapists.
