Information for Patients


Rotator Cuff Injuries

Your rotator cuff is located in your shoulder area. It is made of muscles and tendons. It helps your shoulder to move and stay stable. Problems with the rotator cuff are common. They include tendinitis, bursitis, and injuries such as tears.

Rotator cuff tendons can become inflamed from frequent use or aging. Sometimes they are injured from a fall on an outstretched hand. Sports or jobs with repeated overhead motion can also damage the rotator cuff. Aging causes tendons to wear down, which can lead to a tear.

Some tears are not painful, but others can be very painful. Treatment for a torn rotator cuff depends on age, health, how severe the injury is, and how long you've had the torn rotator cuff.

Treatment for torn rotator cuff includes:

  • Rest
  • Heat or cold to the sore area
  • Medicines that reduce pain and swelling
  • Electrical stimulation of muscles and nerves
  • Ultrasound
  • Cortisone injection
  • Surgery

Wounds and Injuries

Also called: Traumatic injuries

An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.

Other common types of injuries include

  • Animal bites
  • Bruises
  • Burns
  • Dislocations
  • Electrical injuries
  • Fractures
  • Sprains and strains
