General care

  • Wear your removable cast according to your healthcare provider’s instructions.

  • Always keep the removable cast dry. Bathe with your cast out of the water. Hold the body part with the cast outside the tub or shower. Protect it with a large plastic bag. Close the bag with tape or rubber bands. Use 2 layers of plastic to help keep the cast dry. Or you can buy a waterproof shield.

  • If your cast gets wet, dry it with a hair dryer on the cool setting. Don’t use the warm or hot setting. Those settings can burn your skin.

  • Keep the cast clean and away from dirt.

  • Don’t cut or tear the cast. 

  • Keep your cast away from open flames.

  • Don’t expose your cast to heat, space heaters, or a lot of sunlight. Too much heat will cause the cast to change shape.

  • Exercise all the nearby joints that are not limited in movement by the cast. If you have a long leg cast, exercise your hip joint and your toes. If you have an arm cast, exercise your shoulder, elbow, thumb, and fingers.

  • Raise the part of your body that is in the cast. Do this as often as possible during your day. This helps reduce swelling.

Cleaning your cast

  • Clean the removable cast with soap and lukewarm water. Scrub it with a small brush.

  • Use alcohol wipes to rub the inside of the cast. This is to reduce odor and bacteria.

  • Wash the Velcro straps and inner cloth sleeve (stockinet) with soapy water. Then let it air dry.

Follow-up care

Make a follow-up appointment with your healthcare provider, or as advised.
