rotatorisissa

Rotatorisissa, also known as the rotator cuff, is a group of tendons and muscles in the shoulder that stabilize the joint and allow for a wide range of motion. The term originates from the Latin *rotator*, meaning "to turn," reflecting the cuff's role in facilitating shoulder rotation. This complex structure is composed of four primary muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis. Each muscle attaches to the humerus (upper arm bone) via tendons, forming a cuff-like arrangement around the shoulder joint.

The rotator cuff is essential for lifting the arm, rotating it, and maintaining stability during movements. Injuries to this area, such as tears or tendinitis, are common due to repetitive overhead motions, aging, or trauma. Symptoms often include pain, weakness, and limited mobility, particularly when lifting or reaching overhead. Conditions like rotator cuff tendinitis (inflammation of the tendons) or tears (partial or full-thickness) are frequently diagnosed through physical exams, imaging studies like MRI or ultrasound, or diagnostic injections.

Treatment typically begins with conservative measures, including rest, physical therapy, anti-inflammatory medications, and corticosteroid injections. In severe or chronic cases, surgical intervention—such as arthroscopic repair—may be necessary to reattach torn tendons. Prevention involves strengthening shoulder muscles, maintaining proper posture, and avoiding excessive strain on the joint. Proper warm-up and stretching routines can also reduce the risk of injury. Given its critical role in shoulder function, maintaining rotator cuff health is vital for overall upper-body mobility and quality of life.
