Upper Extremity Fracture

Illustration showing the outline and bones of the arm, including the humerus and ulna, and a fracture in the radius.

You have a break (fracture) of the arm, wrist, or hand. This may be a small crack in the bone. Or it may be a major break, with the broken parts pushed out of position. Most fractures will heal without surgery. But you may need surgery if the bones are far out of place or if the break is near the elbow. Treatment is with a special sling called a shoulder immobilizer, or a splint or cast, depending on where the fracture is. This fracture takes 4 to 6 weeks to heal. The cast may need to be changed in 2 to 3 weeks as swelling goes down.

Home care

Follow these guidelines when caring for yourself:

  • If you were given a shoulder immobilizer, leave it in place. This will support the injured arm at your side. This is the best position for bone healing. The shoulder immobilizer can be adjusted. If it becomes loose, adjust it so that your forearm is level with the ground (horizontal). Your hand should be level with your elbow.

  • Put an ice pack on the injured area. Do this for 20 minutes every 1 to 2 hours the first day for pain relief. You can make an ice pack by wrapping a plastic bag of ice cubes in a thin towel. You can put the ice pack inside the sling and directly over the splint or cast. Continue using the ice pack 3 to 4 times a day for the next 2 days. Then use the ice pack as needed to ease pain and swelling.

  • Keep the cast/splint/sling completely dry at all times. Bathe with your cast/splint/sling out of the water. Protect it with a large plastic bag, rubber-banded at the top end. If a fiberglass cast/splint/sling gets wet, you can dry it with a hair dryer.

  • You may use acetaminophen or ibuprofen to control pain, unless another pain medicine was prescribed. If you have chronic liver or kidney disease, talk with your health care provider before using these medicines. Also talk with your provider if you’ve had a stomach ulcer or GI bleeding.

  • Don’t put creams or objects under the cast if you have itching.

Follow-up care

Follow up with your health care provider in 1 week, or as advised. This is to make sure the bone is healing the way it should.

If X-rays were taken, A radiologist will look at them. You will be told of any new findings that may affect your care.

When to seek medical advice

Call your health care provider right away if any of these occur:

  • The cast cracks

  • The plaster cast or splint becomes wet or soft

  • The fiberglass cast or splint stays wet for more than 24 hours

  • Bad odor from the cast or wound fluid stains the cast

  • Tightness or pain under the cast or splint gets worse

  • Fingers become swollen, cold, blue, numb, or tingly

  • You can’t move your fingers

  • Skin around cast becomes red

  • Fever of 101ºF (38.3ºC) or higher, or as directed by your health care provider
