ABSTRACT:
The present invention provides an orthopedic casting article comprising an apertured, extruded sheet. The present invention also provides a method of enclosing a body member, comprising the steps of: heating an apertured, extruded sheet comprising a low temperature thermoplastic polymer having a softening or melting temperature less than about 90.degree. C.; wrapping the article about the body member; and molding the wrapped article about the body member such that the article is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint. The present invention also provides a method of enclosing a body member, comprising the steps of: initiating the curing of an apertured, extruded sheet comprising a viscous curable resin having a sufficient yield stress to resist flow at ambient temperature for extended periods of time; wrapping the article about the body member; and molding the wrapped article about the body member such that the article is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint. The apertured, extruded sheet may optionally contain a filler associated with the resin. The incorporation of fillers adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage.
