Rotator cuff (SITS)

The rotator cuff, often referred to as SITS, comprises four muscles—supraspinatus, infraspinatus, teres minor, and subscapularis—that stabilise the shoulder joint and facilitate arm movement. Understanding the rotator cuff is crucial in diagnosing and managing shoulder injuries, such as rotator cuff tears, which can lead to pain, weakness, and impaired function. These injuries are common in athletes and can significantly impact daily activities and quality of life.
