Rotator Cuff Injury Symptoms & Diagnosis

Symptoms

• Recurrent, constant pain, particularly when reaching overhead
• Pain at night that prevents you from sleeping
• Shoulder muscle weakness, especially when lifting the arm
• Popping or clicking sounds when the shoulder is moved
• Limited range of motion in the shoulder joint

Diagnosis

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 or MRI is taken. The doctor will look for dye that leaks out of the joint, which may indicate a tendon tear.
• MRI scan—a test that uses a strong magnetic field and radio 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—a test that uses sound waves to examine the rotator cuff for inflammation or tears.
