Teres Minor Trigger Points - often associated with Rotator Cuff Injuries
The teres minor decelerates internal rotation of the shoulder joint.
Inhibition in this muscle due to short/ spastic subscapularis, latissimus dorsi, teres major, and pectoralis major muscles sets up the ideal conditions for repetitive stress in sports, such as swimming and rugby, and in any activity involving acceleration through internal/external rotation and flexion/extension of the shoulder complex.
Numbness or tingling will be felt in the fourth and fifth digits of the same arm, as well as pain in the posterior shoulder at the greater tuberosity. Teres minor myofascial trigger points are often sponsored by the subscapularis.
The rotator cuff helps hold the head of the humerus in contact with the glenoid cavity (fossa, socket) of the scapula during movements of the shoulder, thus helping to prevent dislocation of the joint.

Lower facet on greater tubercle of humerus. Capsule of shoulder joint.
As a rotator cuff muscle, helps prevent upward dislocation of shoulder joint. Laterally rotates humerus. Weakly adducts humerus. Antagonists: subscapularis, pectoralis major, latissimus dorsi.
