ABSTRACT:
A hand prosthesis to be utilized in conjunction with an arm that has at least one functional joint and a movable portion of the arm outward of the joint. The prosthesis includes a base that is strapped to the user inwardly adjacent to the functional joint. A pair of plates are hinged at rearward ends and mounted to the base by a ball and socket arrangement. The ball and socket connects one plate to the base while the remaining plate is releasably fastened to the movable portion of the arm. Thus, the base acts as a relatively stationary support for the one plate while the remaining plate may be selectively pivoted about the axis of the hinge to open or close the plates in response to movement of the movable arm portion.
