The bicipital groove separates the greater tubercle from the lesser tubercle. [1] It is usually around 8 cm long and 1 cm wide in adults. [1] The groove lodges the long tendon of the biceps brachii muscle, positioned between the tendon of the pectoralis major muscle on the lateral lip and the tendon of the teres major muscle on the medial lip.
It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure. It is the groove where the long head of biceps tendon runs between the greater and lesser tubercles below the humeral head before inserting into the superior glenoid rim. The lateral bicipital groove is seen on the lateral ...
The tubercles are separated from each other by a deep groove, the bicipital groove (intertubercular groove; bicipital sulcus), which lodges the long tendon of the biceps brachii muscle and transmits a branch of the anterior humeral circumflex artery to the shoulder-joint. It runs obliquely downward, and ends near the junction of the upper with ...
Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
Capsule of shoulder-joint (distended). Anterior aspect. ... (intertubercular groove), it functions to hold the long head of the biceps tendon within the bicipital groove.
Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: . a posterior, rough portion, for the insertion of the tendon of the biceps brachii.
It gives attachment to the capsular ligament of the shoulder joint except at the upper inferior-medial aspects. It is best marked in the lower half of its circumference; in the upper half it is represented by a narrow groove separating the head of the humerus from the two tubercles, the greater tubercle and the lesser tubercle .
The main symptom is generally anterior biceps instability, but the disease can also be characterized by chronic anterior shoulder pain which radiates towards the lateral part of the elbow. [4] In cases of biceps tendinitis, steroids can be injected fluoroscopically at the supraglenoid tubercle to reduce pain associated with the pathology. [5]
