A polycentric hinged ulnar deviation splint for reducing deviation of the fingers in an ulnarward direction and for bringing the fingers into neutral alignment along a mid-longitudinal axis of the hand and forearm which allows free joint motion in all fingers and has no covering of the palm of the hand is disclosed. The splint has a proximal portion and a distal portion which are opposed and conform to the dorsum of the hand. Each extension of the proximal portion and the distal portion are attached by a polycentric hinge which forms a multi-axis polycentric joint in alignment with the metacarpophalangeal joints of the hand. The splint also includes at least one finger alignment component which is attached to the distal portion, as well as a strap for removably fastening the splint on the hand.
