Plaster Splint Care


The following will help you care for your splint at home:

  • It will take up to 48 hours for your plaster splint to fully harden. Don’t put pressure on it during this time or it may break. Don’t walk on foot or leg splints, because they may break, even when dry.

  • To stop swelling under the splint, for the first 48 hours:

    • If the splint is on your arm, keep it in a sling or raised to shoulder level when sitting or standing. Rest it on your chest or on a pillow at your side when lying down.

    • If the splint is on your leg, keep it propped up above the level of your heart when sitting or lying. Sleep with it raised on a few pillows. As much as possible, don't do any crutch walking during this time.

  • Keep the splint or cast dry at all times. Bathe with your splint or cast well out of the water. Protect it with a large plastic bag closed at the top end with a rubber band or tape. If a fiberglass cast or splint gets wet, dry it with a hair dryer.

  • Don't stick objects such as a coat hanger inside splint. Don't put powder or cream inside the splint for itchy skin. If itching doesn't go away call your healthcare provider.

  • Look at the skin around the splint every day.

  • Look at the splint every day to make sure it's intact.
