Teres minor

Medically reviewed by Healthline Medical Team on March 24, 2015

The teres minor is a slim, narrow muscle within the rotator cuff, located in the shoulder. It is involved in the external rotation of the shoulder joint. The other muscles composing the rotator cuff are the supraspinatus, infraspinatus, and subscapularis. It connects the scapula to the humerus, along with the teres major and infraspinatus muscles, which lie on either side and overlap the teres minor. Along with the infraspinatus, the muscle keeps the head of the humerus in place where it joins with the scapula. It is possible for the two muscles to be interconnected by a few fibers. Torn rotator cuff tendons occur commonly amongst athletes in sports involving throwing, such as football, tennis and baseball. Treatment for the condition involves reducing the swelling with rest, ice, and keeping the arm elevated. Depending on the extremity of the injury, surgery may be necessary. Specific arm exercises may be used to strengthen, heal, and protect against possible future tears of the supraspinatus, infraspinatus, subscapularis, and teres minor.
