Caring for a Cast

• When bathing, do not let the cast get wet. The cast can be enclosed in a plastic bag. The top of the bag should be carefully sealed with rubber bands or tape. However, specially designed waterproof cast covers are easier to use and more effective.
• If a cast gets wet, try using a hair dryer, and ask the doctor whether the cast needs to be changed. The cast may be changed because the underlying padding can retain moisture. Moisture can weaken the cast, damage the skin, and make infections more likely.
• Do not push a sharp or pointed object inside the cast (for example, to scratch the skin). Doing so may damage the skin under the cast, and the cast may have to be removed to treat the injury.
• Check the skin around the cast every day and apply lotion to any red or sore areas.
• Rest the affected limb in an elevated position, as needed, to control swelling.
• Do not push or lean on the cast. It may break.
• Pad the edge of the cast with soft adhesive tape, moleskin, tissues, or cloth if the edge of the cast feels rough. The edge of the cast may chafe the skin or cause sores to form.
• When resting, position the cast carefully to prevent the cast's edge from pinching or digging into the skin. A small pillow or pad can be used.
• Immediately contact a doctor if the cast causes persistent pain or feels excessively tight. If swelling is excessive or an odor emanates from under the cast, the cast may have to be removed within hours.
• To decrease swelling and prevent stiffness, periodically move fingers or toes that stick out from the cast.
