Abstract
Abstract An improved wrist brace maintains the wrist extended and slightly ulnar deviated (so called position of function), providing support and impact counterforce bracing. The brace is utilized for play by sufferers of "tennis elbow" (tendonitis of the conjoined tendon of the extensor communis and extensor carpi radialis brevis at the insertion into the lateral epicondyl of the humerus), reduced subluxation of the wrist ("sprain"), and/or rheumatoid arthritis of the wrist. The brace includes a semirigid, fluid-passing (e.g., woven) semiflexible outer backer layer, and an inner porous layer, e.g., and open pore plastic. Particular forms of buckle and strapping are secured at opposite ends of the elongated backer-foam laminate to secure the brace in place, as by hook and eye type cooperating fastener strips.
