Discharge Instructions: Caring for Your Removable Cast

You will be going home with a removable cast (sometimes referred to as a splint). A cast helps your body heal by holding your injured bones or joints in place. A damaged cast can keep the injury from healing well. Take good care of your cast. If the cast becomes damaged, it may need to be replaced. 

You have a broken ___________________ bone.

This bone is located in your ____________.

General Care

  • Wear your removable cast according to your doctor’s instructions.

  • Don’t cut or tear the cast. 

  • Keep your removable cast away from open flames.

  • Don’t expose your removable cast to heat, space heaters, or prolonged sunlight. Excessive heat will cause the removable cast to change shape.

  • Exercise all the adjacent joints not immobilized by the cast. If you have a long leg cast, exercise your hip joint and your toes. If you have an arm cast or splint, exercise your shoulder, elbow, thumb, and fingers.

  • Elevate the part of your body that is in the cast. 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 removable cast to reduce odor and bacteria.

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


Make a follow-up appointment as directed by our staff.
