An orthopedic casting material having strength and porosity characteristics which heretofore have been associated only with high modulus fibers, while using casting material comprising a fabric made from a multi-filament, low modulus fiber. The fabric is impregnated with a reactive resin which hardens by wetting with a curing agent. A method for making an orthopedic cast and the resulting cast product are also disclosed, as is coloring of the cast product in a variety of desired colors and patterns.

Low modulus synthetic fiber casting system

A system for improving the handling of a resin coated substrate for molding and smoothing into an orthopedic cast includes a core which is coated with a substance which is substantially inert to the resinous prepolymer in a sealed storage pouch. Water, used to activate the resinous prepolymer, carries the coating to the surface of the substrate, thereby improving handling during the molding process. During normal operation, the cast applier removes the resin coated or impregnated substrate from the storage container and dips it in a water bath to initiate the polymerization process. After removal from the water bath, the applier wraps the substrate around a patient's limb and molds and smooths the substrate to form an orthopedic cast. Once the core about which the resin coated substrate is wrapped is exposed to water, the lubricant is transferred by the water to the outside portion of the cast tape, reducing the tackiness of the cast tape, thereby facilitating its overall handling. This transfer is very limited in nature, and only puts the lubricant in contact with the cast tape at the point which will be used to form the outer most layer of the cast.
