Muscles comprising rotator cuff Supraspinatus Infraspinatus Teres Minor Subscapularis
Slide 16-

Cause: the rotator cuff can be torn from a single traumatic injury. A cuff tear may also happen at the same time as another injury to shoulder,such as a fracture or dislocation. Most tears, however, are the result of overuse of these muscles and tendons over a period of years. People who are especially at risk for overuse are those who engage in repetitive overhead motions. These include participants in sports such as baseball, tennis, weight lifting, and rowing.
Slide 17-

…. injury to 1 or more of the 4 muscles in the shoulder. Rotator cuff tears are most common in people who are over the age of 40. Younger people tend to have rotator cuff tears following acute trauma or repetitive overhead work or sports activity. Rotator cuff tear may often happen as a result of wear and tear.
Slide 18-

Symptoms: Pain on the lateral aspect of the shoulder Often worse at night When lifting the arm may radiate to deltoid insertion Weakness, instability, tenderness (There may be increase in the pain and weakness experienced when elevating or rotating the arm) Atrophy or thinning of the muscles about the shoulder

How is it diagnosed? Diagnosis of a rotator cuff tear is based on the symptoms and physical examination. X-rays, and imaging studies, such as MRI or ultrasound, are also helpful. An MRI can sometimes tell how large the tear is, as well as its location within the tendon itself or where the tendon attaches to bone. Shoulder pain is variable and does not always correspond to the size of the tear.
