It runs obliquely downward and ends near the junction of the upper with.
Bicipital groove image. 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 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. Proximal thickened biceps tendon transverse proximal thickened biceps tendon transverse proximal normal biceps tendon transverse biceps tendon tendinosis with a thickened biceps tendon and effusion. It also transmits a branch of the anterior humeral.
Non visualization of long head of biceps tendon in bicipital groove with medially displaced tendon. It also transmits a branch of the anterior humeral. It contains the tendon of the long head of the biceps brachii muscle which is ensheathed in a synovial reflection of the. The position of the lbt with respect to the bicipital groove was measured by two musculoskeletal radiologists on three levels along the bicipital groove on axial mr images in neutral position and in external and internal rotation of the shoulder.
Diagnosis is best made on axial mr images where the bicipital groove is seen to be empty and the tendon can be identified medially. The shape of the lbt was classified as round oval flat or comma shaped and the orientation of. Ultrasound images clips biceps tendon tendinosis with a thickened biceps tendon and effusion in an irregular bicipital groove. 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 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 transducer was placed at the upmost level of the bicipital groove when obtaining the short axis image of the biceps tendon. The bicipital groove is typically 4 6 mm deep 1. The long axis of the subscapularis tendon was visualized during.
From these images the bicipital groove surface was segmented manually by a graduate student under the direction of a board certified radiologist.
