conjoint tendon of shoulder i.e short head of the biceps and coracobrachialis, acting as a sling on the subscapularis and capsule with the arm abducted and externally rotated; increasing or restoring the glenoid bone; and; repair of the capsule to the stump of coracoacromial ligament. [2]
The coracobrachialis muscle muscle in the upper medial part of the arm. It is located within the anterior compartment of the arm. It originates from the coracoid process of the scapula; it inserts onto the middle of the medial aspect of the body of the humerus. It is innervated by the musculocutaneous nerve. It acts to adduct and flex the arm.
Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery, is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor. The procedure is common among collegiate and professional athletes in ...
The musculocutaneous nerve is a mixed branch of the lateral cord of the brachial plexus derived from cervical spinal nerves C5-C7. It arises opposite the lower border of the pectoralis major. It provides motor innervation to the muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis. [1]
The biceps is one of three muscles in the anterior compartment of the upper arm, along with the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply. [1] The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid ...
38485. Anatomical terms of muscle. [edit on Wikidata] The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. [1][2] It is also capable of both pronation and supination, depending on the position of the forearm. [2] It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and ...
Supinator always acts together with biceps, except when the elbow joint is extended. [7] It is the most active muscle in forearm supination during unresisted supination, while biceps becomes increasingly active with heavy loading. [8] Supination strength decreases by 64% if supinator is disabled by, for example, injury.
FMA. 25943. Anatomical terminology. [edit on Wikidata] The coracoacromial ligament is a strong triangular ligament between the coracoid process and the acromion. It protects the head of the humerus. Its acromial attachment may be repositioned to the clavicle during reconstructive surgery of the acromioclavicular joint (shoulder joint).
