Rotator Cuff

What is a rotator cuff injury?

Your rotator cuff consists of muscles and tendons that hold your shoulder in place. It is one of the most important parts of your shoulder.

Your rotator cuff allows you to lift your arms and reach upward. In 2008, close to 2 million people in the United States went to their health care providers because of a rotator cuff problem. A rotator cuff tear is a common cause of pain and disability among adults.

What causes a rotator cuff injury?

There are two main causes of rotator cuff tears: injury and degeneration. An injury to the rotator cuff, such as a tear, may happen suddenly when falling on an outstretched hand. It may also develop over time due to repetitive activities. Rotator cuff tears may also happen due to aging, with degeneration of the tissues.

What are the symptoms of rotator cuff tear?

The following are the most common symptoms of a rotator cuff tear. However, you may experience symptoms differently. Symptoms may include:

• Recurrent pain, especially with certain activities
• Pain that prevents you from sleeping on your injured side
• Grating or cracking sounds when moving your arm
• Limited ability to move your arm
• Muscle weakness

The symptoms of a rotator cuff tear may resemble other conditions or medical problems. Always consult your health care provider for a diagnosis.

How is a rotator cuff injury diagnosed?

In addition to a complete medical history and physical examination, diagnostic procedures for a rotator cuff injury may include the following:

• X-ray. A diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
• Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.

A rotator cuff may tear partially or fully. Partial-thickness tears do not completely sever the tendon from the shoulder.

How is a rotator cuff injury treated?

Your health care provider will determine the specific treatment for a rotator cuff injury, based on:

• Your age, overall health, and medical history
• Extent of the condition
• Your tolerance for specific medications, procedures, or therapies
• Expectations for the course of the condition
• Your opinion or preference

Treatment may include:

• Rest
• Nonsteroidal anti-inflammatory medications
• Strengthening and stretching exercises
• Ultrasound therapy
• Corticosteroid injection
• Surgery (for severe injuries)

When should I call my health care provider?

Notify your health care provider if:

• Your pain becomes worse or begins to interfere with your normal activities or ability to sleep well
• You can’t use your shoulder as much as you were able to previously
