Polycentric hinged ulnar deviation hand splint
First Claim
1. A polycentric hinged ulnar deviation splint comprising:
- (a) a substantially "U"-shaped proximal portion having a pair of spaced-apart proximal extensions,(b) a substantially "U"-shaped distal portion having a pair of spaced-apart distal extensions;
(c) the proximal portion and the distal portion being in opposition and being sized and configured to conform to the dorsum of a hand of a user, one proximal extension being associated with one distal extension,(d) at least one polycentric hinge for hingedly attaching an associated proximal extension to an associated distal extension;
(e) at least one finger alignment component attached to the distal portion; and
(f) means for removably fastening the splint on a hand of a user.

Abstract
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.
