The overuse of the coracobrachialis can lead to stiffening of the muscle. Common causes of injury include chest workouts or activities where you have to press your arm very tight towards your body - e.g. work on the rings in gymnastics.^[4] Symptoms of overuse or injury are pain in the arm and shoulder, radiating down to the back of the hand. In more severe cases, the musculocutaneous nerve can get trapped, causing disturbances in sensation to the skin on the radial part of the forearm and weakened flexion of the elbow, as the nerve also supplies the biceps brachii and brachialis muscle.^[5]

The coracobrachialis is the smallest of the three muscles that attach to the coracoid process of the scapula. (The other two muscles are pectoralis minor andbiceps brachii.) It is situated at the upper and medial part of the arm.

It arises from the apex of the coracoid process, in common with the short head of the biceps brachii, and from the intermuscular septum between the two muscles.

It is inserted by means of a flat tendon into an impression at the middle of the medial surface and border of the body of the humerus (shaft of the humerus) between the origins of the triceps brachii and brachialis.

Innervation[edit]

It is perforated by and innervated by the musculocutaneous nerve. which arises from the anterior division of the upper (C5, C6) & middle trunks (C7) of the brachial plexus.

The action of the coracobrachialis is to flex and medially rotate the arm. Also, the coracobrachalis resists deviation of the arm from the frontal plane during abduction.^[1] Therefore, the contraction of the coracobrachialis leads to two distinct movements at the shoulder joint. It both draws the humerus forward, causing shoulder flexion, and draws the humerus toward the torso, causing shoulder adduction. To a smaller extent, it also turns the humerus inwards, causing inward rotation.^[2] Another important function of the coracobrachialis is the stabilization of the humeral head within the shoulder joint, especially when the arm is hanging freely at a person’s side.^[3]

Clinical significance[edit]

The overuse of the coracobrachialis can lead to stiffening of the muscle. Common causes of injury include chest workouts or activities where you have to press your arm very tight towards your body - e.g. work on the rings in gymnastics.^[4] Symptoms of overuse or injury are pain in the arm and shoulder, radiating down to the back of the hand. In more severe cases, the musculocutaneous nerve can get trapped, causing disturbances in sensation to the skin on the radial part of the forearm and weakened flexion of the elbow, as the nerve also supplies the biceps brachii and brachialis muscle.^[5] Actual rupture to the coracobrachialis muscle is extremely rare. Very few case reports exist in the literature, and it is reported to be caused by direct trauma to the contracted muscle. Avulsion of the muscle's origin from the coracoid as a result of indirect forces is even more unusual.^[6]
