How To Apply a Cast
Introduction
A cast is a rigid, circumferential, layered composite dressing intended to immobilize a body part, typically an extremity. Casts usually consist of a soft fabric sleeve on the skin, over which is placed a layer of soft padding, followed by multiple, thin layers of flexible strips of plaster or fiberglass that quickly harden through a chemical reaction. Similar material is used to make splints, which differ mainly in that the plaster or fiberglass is not circumferential.
