Rotator Cuff Tear

Diagnosis

Symptoms of a rotator cuff tear include:

• recurrent, constant pain, particularly with overhead activities
• pain at night that prevents you from sleeping
• muscle weakness, especially when lifting the arm
• popping or clicking sounds when the shoulder is moved
• limited range of motion in the shoulder joint

The doctor will ask about your symptoms and medical history, and perform a physical exam. The doctor will carefully examine your shoulder. You will be asked to move your shoulder in several directions. Tests may include:

• x-rays, to rule out fractures and bone spurs
• arthrogram
  Dye is injected into the shoulder joint and then an x-ray is taken. The doctor will look for dye that leaks out of the joint, which indicates a tendon tear.
• magnetic resonance imaging (MRI) scan
  This is a test that uses magnetic waves to make pictures of the inside of the shoulder. This will show bones and tendons, and is an excellent way to determine either large or small tears of the cuff.
• arthroscopy
  A thin, lighted tube is inserted through a small incision in the shoulder to look at the structures inside the shoulder. Arthroscopy can also be used for treatment.
• ultrasound
  Although relatively uncommon in the United States, ultrasound can be useful in examining the rotator cuff for inflammation or tears.
