Biceps Groove Humerus

The long head of biceps lhb tendon is usually located inferiorly in the bicipital groove held there by the biceps pulley the stabilization role of the transverse humeral ligament is controversial 3 as it moves superiorly it arches through the rotator cuff interval where it is held by a sling. The structure indicated is the intertubercular sulcus of the humerus. As the tendon of biceps brachii enters the forearm a connective tissue sheet is given off the bicipital aponeurosis.

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.

Biceps groove humerus. It also transmits a branch of the anterior humeral. 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. Originates at the supraglenoid tubercle above the glenoid cavity of the scapula it lies within the intracapsular space but it still remains extrasynovial. The bicipital groove is typically 4 6 mm deep 1.

From its origin on the glenoid the long head remains tendinous as it passes through the shoulder joint and through the intertubercular groove of the humerus. The long biceps tendon lbt sits within the bg. The biceps brachii muscle biceps is a large thick muscle of the arm consisting of two heads. It contains the tendon of the long head of the biceps brachii muscle which is ensheathed in a synovial reflection of the.

The biceps brachii is a two headed muscle. The long biceps tendon makes a sharp turn at the humeral head and continues its course in the bicipital groove intertubercular sulcus. Dislocation of the long head of biceps tendon is one of the complications of shoulder injury. L bis twice caput head.

Biceps tendinitis is a disorder of the tendon around the long head of the biceps muscle. Inflammation of the biceps tendon within the intertubercular bicipital groove is called primary biceps. Although the majority of the muscle mass is located anteriorly to the humerus it has no attachment to the bone itself. The bicipital groove also known as the intertubercular sulcus or sulcus intertubercularis is the indentation between the greater and lesser tuberosities of the humerus that lodges the biceps tendon.

The bicipital groove bg of the proximal humerus is a groove in the humeral head formed by the medial and lateral tuberosities fig. The intertubercular sulcus also known as the intertubercular groove or bicipital groove is a groove separating the greater and lesser tubercles of the humerus. The tendon of the long head of the biceps muscle runs in this groove and attaches on the supraglenoid tubercle of the scapula. The bg prevents the lbt from dislocating during movement of the arm.

The biceps muscle has two heads the short head and the long head distinguished according to their origin at the coracoid process and supraglenoid tubercle of the scapula respectively.
