Custom-fitting lumbosacral support pad

A lumbosacral support pad for being custom-fitted to the lumbosacral area of the back and comprising:

• (a) an initially flexible fabric layer comprised of a plurality of overlaid thicknesses of fiberglass impregnated or coated with a moisture-curable resin which hardens upon curing to form a rigid structure which retains the shape into which it is molded during curing;
• (b) a flexible cushion layer positioned on an inner side of said fabric layer for being placed closest to the back;
• (c) a protective covering layer enclosing at least one major surface of the fabric layer, the fabric layer, said protective covering layer, and said flexible cushion layer being formed in an anatomically-correct shape for being applied and custom-molded to the lumbosacral region of the back;
• and
• (d) said anatomically-correct shape being defined by two opposing and converging side edges of the pad and at least one convex side edge of the pad, wherein said convex side edge of the pad is adapted to be oriented generally laterally from one side of the back to the other below said converging side edges, said support pad being contained until use within a disposable moisture-proof protective pouch within which the support pad is sealed for storage in the absence of moisture until the support pad is removed from said pouch for being moistened and molded to the back, whereupon the pouch is disposed of.
