An infraspinatus tendon tear is a common injury that can occur in the shoulder. The infraspinatus tendon is one of the four rotator cuff tendons that help stabilize and move the shoulder joint.. An infraspinatus tendon tear can be caused by a traumatic injury, such as a fall or direct blow to the shoulder, or by repetitive strain on the shoulder joint over time.The supraspinatus tendon is inserted into the superior facet of the greater tubercle of the humerus. The distal attachments of the three rotator cuff muscles that insert into the greater tubercle of the humerus can be abbreviated as SIT when viewed from superior to inferior (Supraspinatus, Infraspinatus, and Teres minor).
