bicipital groove

The medial bicipital groove is seen on the surface anatomy of the upper arm.

Tenderness where the biceps meets the shoulder (bicipital groove).

It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure.

Between the greater tubercle and the lesser tubercle is the intertubercular sulcus (bicipital groove).

The inflammation usually occurs along the groove (bicipital groove) where the tendon passes over the humerus to attach just above the shoulder joint.

They all end in a flat tendon, about 5 cm in breadth, which is inserted into the lateral lip of the bicipital groove of the humerus.

By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled back so that the bicipital groove faces the coracoacromial ligament.

The infraspinatus and teres minor fuse near their musculotendinous junctions, while the supraspinatus and subscapularis tendons join as a sheath that surrounds the biceps tendon at the entrance of the bicipital groove.

The tubercles are separated from each other by a deep groove, the intertubercular groove (bicipital groove), which lodges the long tendon of the biceps brachii muscle and transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
