Hand orthoses

Abstract

Hand orthotics are provided for protecting and/or supporting phalanges, metacarpals and/or ligaments of the hand providing thin, lightweight, moldable devices that form to the digits of and to the hand to provide shock absorption and limited range of motion in flexion and extension movements of the digits of the hand, but mitigate or prevent hyperextension. Each orthotic has several plates of thermal plastic, pre-molded carbon fiber or the like that are generally, if not entirely, inflexible and interlinked through limited range of motion hinges, overlapping, and/or abutting plates that accommodate stability and protection. The plates are contained within, on top, underneath, or permutations of these, a form fitting material (e.g. neoprene or vinyl) to maintain a tight fit to the hand, digits and wrist. A thumb plate is hinged to an upper or lower hand plate of the device and includes a loop for receiving the thumb.
