Abstract
The present invention provides a method of making an orthopedic casting article comprising an apertured, extruded sheet. The method involves the steps of charging an extrudable material selected from the group consisting of low temperature thermoplastic polymers and viscous curable resins to an extruder; and extruding the material through a die to form an apertured sheet. The sheet 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 sheet preferably has at least 20 percent aperture volume. 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.
