Long head biceps tendon

The long head of the biceps tendon (LHB) originates from the supraglenoid tuberosity and partly from the superior labrum, having a common attachment with the superior glenohumeral ligament. This conjoined structure is known as the bicipital-labral complex (BLC) or biceps anchor, where the fibrous tissue of the labrum blends with the biceps tendon

After his origine, the long head of the biceps tendon (LHB) has an oblique intra-articular course, traverses the rotator interval, and must take a 30- to 45-degree turn along the anterior surface of the humerus before it exits the joint between the lesser and greater tuberosities into the bicipital groove.
