The superior glenohumeral ligament (SGHL) travels from the anterosuperior glenoid labrum to the humerus forming a pulley/sling medial to the bicipital groove.This helps to prevent medial or anterior-inferior translation of the long head of the biceps (LHB) tendon from the groove.Its principal function, however, is the primary static restraint to inferior translation at 0° of shoulder abduction.
