Bicipital Groove Nerve

The nerve courses through the lower part of the extensor compartment and disappears into the forearm by passing between the humeral and ulnar heads of.

Bicipital groove nerve. Defined three distinct anatomic zones of the bicipital groove. D groeve a groove between the greater and lesser tubercles of the humerus for passage of the tendon of the long head of the biceps muscle. The median nerve traverses three successive arches or tunnels to enter the forearm deeply namely the bicipital aponeurosis pronator teres and flexor digitorum superficialis figures 41 6 and 41 7 it first passes under the bicipital aponeurosis which is a thick layer of fascia attaching the biceps brachii to the proximal forearm flexor mass. In order to accurately diagnosis and treat the patient shoulder arthroscopy was performed using standard posterior and anterior portals.

It also transmits a branch of the anterior humeral. The bicipital groove which is bounded by the lesser tuberosity medially and the greater tuberosity laterally contains the tendon of the long head of the biceps brachii muscle lhbt. Zone 1extends from the articular margin to the distal margin of the subscapularis tendon zone 2 extends from the distal. It also transmits a branch of the anterior humeral.

The radial sulcus also known as the musculospiral groove radial groove or spiral groove is a broad but shallow oblique depression for the radial nerve and deep brachial artery it is located on the center of the lateral border of the humerus bone. The bicipital groove intertubercular groove sulcus intertubercularis is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle the bicipital groove lodges the long tendon of the biceps brachii between the tendon of the pectoralis major on the lateral lip and the tendon of the teres major on the medial lip. Within the medial bicipital groove course the brachial artery and both the ulnar and median nerves. Bicipital groove of humerus intertubercular sulcus injury would inhibit ability to do a pull up exercise 2.

The surface marking of the nerve is along a line from the medial bicipital groove behind coracobrachialis to the point behind the medial epicondyle of the humerus where it is readily palpable. Primary flexor of elbow injury would inhibit ability to perform curls with hands pronated or supinated. The biceps brachii muscle is supplied by the musculocutaneous nerve c5 c6 a branch of the brachial plexus. From the posterior portal a fusiform mass parallel and adjacent to the long head of the biceps tendon was observed figure figure2a.

The lateral bicipital groove contains the radial nerve. Muscle name origin insertion action nerve practical application 1. The bicipital groove intertubercular groove sulcus intertubercularis is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle the bicipital groove lodges the long tendon of the biceps brachii between the tendon of the pectoralis major on the lateral lip and the tendon of the teres major on the medial lip.
