ABSTRACT:
A thumbguard 50 has a unique dynamization strap 30 which assists is resisting abduction of the basal joint. The strap 30 is contoured to fit neatly about a wearer's hand and be connected at both ends to adjacent portions of glove 12. Enlarged regions 34 and 36 assist in applying sufficient pressure across the surface of the hand to achieve abduction. Thumb abduction maximizes basal joint contact area and minimizes shear forces by maintaining the direction of force perpendicular to the joint surface. The dynamic nature of the strap 30 increases support pressure as the force of opposition increases, but still allows a comfortable degree of thumb and basal joint motion.
