Imaging Review of Subscapularis Tendon and Rotator Interval Pathology

Figure 2

Anatomy of the rotator interval. Sagittal view of the humerus. The supraspinatus tendon (SST) and subscapularis tendon (SSCT) are traversing laterally superior and anterior to the humeral head. The long head of the biceps tendon (LHBT) is anterior to the SSCT after it originates from the superior glenoid. The coracohumeral ligament (CHL) originates from the coracoid process (C) as it extends between the SST and SSCT, abutting the superior glenohumeral ligament (SGHL). The acromion process (A) is also shown. IST = infraspinatus tendon; TMT = teres minor tendon (illustration by Zohaib Ahmad).
