Bicipital Groove Surface Anatomy

About 23 mm distal to radial head articular surface.

Bicipital groove surface anatomy. It should be distinguished from the bicipital groove or intertubercular sulcus which is not a surface anatomy structure. The transverse humeral ligament connects the lesser and greater tubercles. 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 head caput humeri the head nearly hemispherical in form 54 is.

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. From these images the bicipital groove surface was segmented manually by a graduate student under the direction of a board certified radiologist. In this project we investigate the relationship between the 3d shape of the bicipital groove and the incidence of pathology of the long biceps tendon. 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.

Upper extremity the upper extremity consists of a large rounded head joined to the body by a constricted portion called the neck and two eminences the greater and lesser tubercles. The pulse of the brachial artery can be felt in the medial bicipital groove.

Stay safe and healthy. The bicipital groove is typically 4 6 mm deep 1. It also transmits a branch of the anterior humeral. The bicipital groove is an osseous groove formed in the humeral head by the medial and lateral tuberosities.

207 208 is the longest and largest bone of the upper extremity. It serves to retain the long head of the biceps brachii. It was critical to distinguish between the cortical and endosteal surfaces during segmentation to ensure that the surface that comes in contact with the lbt was the one extracted fig.
