Bicipital Groove Anatomy

Notice that the supraspinatus tendon is parallel to the axis of the muscle.

Bicipital groove anatomy. Axial anatomy and checklist. Notice that the biceps tendon is attached at the 12 o clock position. The insertion has a variable range. It also transmits a branch of the anterior humeral.

The bicipital groove is typically 4 6 mm deep 1. Notice superior labrum and attachment of the superior glenohumeral ligament. The medial bicipital groove is seen on the surface anatomy of the upper arm it is formed by the longitudinal hollow between the biceps and triceps muscles. 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.

Abstract introduction pathology in the bicipital groove can be a source of anterior shoulder pain. 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. The tendon is exposed on the anterior shoulder as it passes through the humeral bicipital groove and inserts onto the superior aspect of the labrum of the glenohu. Bicipital groove or intertubercular groove divides the lesser and greater tubercles and afterwards proceeds interiorly over the proximal shaft of the humerus the tendon of the long head of the biceps brachii travels via this sulcus.

It contains the tendon of the long head of the biceps brachii muscle which is ensheathed in a synovial reflection of the. It should be distinguished from the bicipital groove or intertubercular sulcus which is not a surface anatomy structure. 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 greater and lesser tubercles of humerus are separated from each other by a deep groove the intertubercular groove bicipital groove which lodges the long tendon of the biceps brachii 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 the middle third of the bone.

The pulse of the brachial artery can be felt in the medial bicipital groove. Many studies have compared treatment techniques for the long head biceps tendon lhbt without sho. It also transmits a branch of the anterior humeral. Bicipital tendinitis or biceps tendinitis is an inflammatory process of the long head of the biceps tendon and is a common cause of shoulder pain due to its position and function.

The long head of biceps brachii muscle runs along this groove. A deep intertubercular sulcus a k a. This is not always the case.
