The physician may notice an enlarged pronator teres muscle.
The nerve enters the cubital fossa medial to the brachialis tendon and passes between the two heads of the pronator teres.
The pronator quadratus and the pronator teres are either reduced or absent.
Hence, restricted external rotation can encourage adaptive shortening and thickening of the internal rotators of the shoulder principally the teres major and subscapularis.
The pectoralis major, teres major, and latissimus dorsi insert at the "intertubercular groove" of the humerus.
The axillary nerve is a branch of the brachial plexus that innervates the deltoid and teres minor muscles.
In pronator teres syndrome, specifically, immobilization of the elbow and mobility exercise within a pain-free range are initially prescribed.
Its upper third consists of a prominent ridge, the crest of the lesser tubercle, which gives insertion to the tendon of the teres major muscle.
