Biceps Groove Humerus

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.

Biceps groove humerus. 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 tendon of the long head of the biceps muscle arises from the tubercle on the superior aspect of the glenoid fossa. The intertubercular groove or also known as the bicipital sulcus is a deep groove that begins between the two tubercles and extends longitudinally down the proximal shaft of the humerus.

The long biceps tendon makes a sharp turn at the humeral head and continues its course in the bicipital groove intertubercular sulcus. The long head of biceps brachii muscle runs along this groove. L bis twice caput head. It also transmits a branch of the anterior humeral.

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 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 groove is occupied by a long head of biceps tendon surrounded by synovial sheath and ascending branch of the anterior circumflex humeral artery. The complete ossification of the transverse humeral ligament or muscle fibres is being reported for the first time.

The transverse humeral ligament connects the lesser and greater tubercles and bridges this. The bg prevents the lbt from dislocating during movement of the arm. The biceps brachii muscle biceps is a large thick muscle of the arm consisting of two heads. Magnetic resonance imaging was used in 41 live volunteers and 9 cadavers to measure the distance from the biceps groove to a line drawn perpendicular to the midpoint of the humeral articular surface.

It contains the tendon of the long head of the biceps brachii muscle which is ensheathed in a synovial reflection of the. A cadaver model with a plastic humeral prosthesis was used to convert this biceps distance into an angular measurement. It also transmits a branch of the anterior humeral. The bicipital groove bg of the proximal humerus is a groove in the humeral head formed by the medial and lateral tuberosities fig.

The long biceps tendon lbt sits within the bg. Vincent davis dc pt dnbpm. The bicipital groove is typically 4 6 mm deep 1.
