Casts and splints are hard wraps used to support and protect injured bones, ligaments, tendons, and other tissues. They help broken bones heal by keeping the broken ends together and as straight as possible. Casts and splints also help with pain and swelling and protect the injured area from more harm.
A cast wraps all the way around an injury and can only be removed in the doctor’s office. All casts are custom-made with fiberglass or plaster.
A splint is like a “half cast.” The hard part of a splint does not wrap all the way around the injured area. It is held in place by an elastic bandage or other material. Unlike casts, splints can be easily removed or adjusted. Many splints are custom-made from fiberglass or plaster.
