Caring for Your Cast: Your Daily Guide

A cast holds a broken bone still while it heals. Good cast care controls swelling, protects your skin, and helps you spot problems early.

Control swelling

  • For the first 24 to 72 hours, prop the cast on pillows above the level of your heart.
  • Use ice over the cast as your care team tells you. Keep the ice in a sealed bag so the cast stays dry.
  • Wiggle your fingers or toes often.

Keep it dry

  • Cover the cast with a plastic bag or cast cover to bathe.
  • Never soak it in a tub, pool, or hot tub.
  • If it gets damp, dry it with a hair dryer on the cool setting.

Protect your skin

  • Never put anything inside the cast to scratch.
  • For itching, blow cool air from a hair dryer into the cast.
  • Do not put powder or lotion inside. Do not pull out the padding.

Check your fingers or toes

  • Several times a day, compare them with the other side.
  • They should be pink, warm, move easily, and feel normal.

Protect the cast

  • Never cut, trim, or remove the cast.
  • Put weight on the limb only when your provider says.

Call your provider today if you have

  • A bad smell or fluid coming from the cast
  • A warm spot on the cast
  • A cast that is cracked, soft, wet, or loose
  • Red or sore skin at the edges

Call 911 or your local emergency number if you have

  • Pain that your pain medicine does not help
  • Pain when you move your fingers or toes
  • Numbness, tingling, or fingers or toes you cannot move
  • Pale, blue, or cold fingers or toes
  • Sudden shortness of breath or chest pain
  • Call 911 or go to the emergency room right away. Do not wait.
