Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures-most often a broken bone (or bones), in place until healing is confirmed.
