Abstract:
A wrist splint assembly for being custom-fitted to a hand and wrist to be supported, comprising:(a) a first splint for being positioned against and formed to the volar aspect of the hand and wrist, and a second splint for being positioned against and formed to the dorsal aspect of the hand and wrist, each of said first and second splints defining a concave side edge extending inwardly toward the longitudinal axis of the splint for permitting ease of movement of the thumb and associated carpometacarpal joint of the hand against which the splint is positioned, and including: (i) an inner cushion layer for being placed on and conformed to the shape of the hand and wrist; (ii) an initially flexible intermediate layer overlying said inner cushion and comprising a substrate impregnated with a moisture-curable resin that hardens upon curing to form a rigid structure of the substrate that retains a shape into which it is molded during curing for maintaining the flexible inner cushion layer in a conforming shape against the hand and wrist; (iii) a flexible outer layer overlying the intermediate layer and attached to the inner cushion layer for enclosing the intermediate layer for forming the inner layer, intermediate layer and outer layer into a single, integrated splint structure; and (b) a support for retaining the first and second splints in position on the hand and wrist during use of said splint assembly.
