Bicipital Groove Diagram

By far the most common direction of tendon displacement is medial.

Bicipital groove diagram. The bicipital groove of the proximal humerus is formed by the medial and lateral tuberosities and serves to retain the long biceps tendon in its proper place as the arm moves. When the biceps contracts it pulls the forearm up and rotates it outward. The long head of biceps brachii muscle runs along this 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.

It serves to retain the long head of the biceps brachii. Diagram shows normal a and the hourglass biceps tendon b. The tendon that attaches the biceps muscle to the forearm bones radius and ulna is called the distal biceps tendon. The bicipital groove crenshaw kilgore 1966.

It also transmits a branch of the anterior humeral. In the remaining patient a weight lifter the tendon was replaced in its anatomical location after the sulcus had been deepened with care taken to preserve the gliding surface of the floor of the groove. Include the bicipital groove and the bicipital tendon long head of biceps. The transverse humeral ligament connects the lesser and greater tubercles.

Biceps tendinitis is a disorder of the tendon around the long head of the biceps muscle. The bicipital groove is an osseous groove formed in the humeral head by the medial and lateral tuberosities. The predeltoid bursa the biceps tendon bursa the subacromial bursa these three areas are the main sites of the usual irritation that the practitioner sees in the shoulder. A dislocated biceps tendon is defined as a tendon that has no contact with the bicipital groove whereas a subluxed biceps tendon retains some contact with the groove.

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. Diagram cf the peroperative jinding in jive. Inflammation of the biceps tendon within the intertubercular bicipital groove is called primary biceps. The bursae that are most prevalent are.

The tendon of the long head of the biceps brachii muscle the long biceps tendon lbt attaches at its anchor to the superior glenoid tubercle from this position it courses intraarticularly to the entrance of the bicipital groove between the major and lesser tubercles of the proximal humerus runs caudally inside the groove and eventually leaves the groove to end in the. 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.
