Muslin Casting Sock
A thin, woven cotton tubular fabric applied over the limb prior to plaster-of-Paris casting to protect the skin and provide a smooth cast interior surface.
Full Definition
A muslin casting sock (also called a stockinette) is a seamless, tubular cotton fabric used as a preliminary layer when applying plaster-of-Paris or fibreglass casting material for orthotic model-making. It protects the patient's skin from abrasion and heat generated during plaster setting, and its weave texture prevents the cast from adhering directly to skin or hair. In orthotic fabrication documentation, editors should note that 'muslin casting sock' and 'stockinette' are used interchangeably, though 'stockinette' may also refer to synthetic stretch fabrics used in prosthetics. The term should not be confused with 'casting liner' or 'suspension sleeve,' which are prosthetic components. Accurate terminology in fabrication records prevents material substitution errors.
Usage
Usage note: Clarify whether 'stockinette' refers to cotton (orthotic casting) or synthetic stretch fabric (prosthetic) when the context is ambiguous.
