Cast Care

Many people have written with questions regarding the proper care for a cast. Casts, made of plaster or fiberglass, are applied to keep injured bones properly aligned and protected while healing occurs. 

In general, cast care involves the following steps:

  • Keep the cast dry. While bathing, cover the cast with a plastic bag to protect it from splashing. If the cast gets damp, use a hair dryer on "low" or "cool" setting to help dry the cast.
  • If the cast breaks, cracks, or becomes soaked with water, tell your doctor.
  • Cover rough cast edges with adhesive tape to prevent skin irritation.
  • Inspect the skin at the cast's edges twice a day.  Call your doctor if you notice any of the following in the area outside the cast:
    • redness
    • irritation
    • swelling
    • sores
    • darkening or paleness of skin
    • numbness or tingling
    • difficulty moving the limb
    • coldness
  • Never use lotions, creams or powder under the cast.
  • Do not insert anything under the cast, even to scratch the skin if it itches.
  • If pain under the cast becomes worse after the first 24 hours or there is a bad odor from inside, call your doctor.
  • Keep small objects away from young children who have casts; they may insert objects into the cast and cause injury.

Most people heal very well after their cast is applied.

Once a cast is removed, the extremity may look smaller. Exercise will help rebuild muscle and restore normal appearance.
