3pp® Polycentric Hinged Ulnar Deviation Splint uses safe, mild-to-moderate force to align hand. Dorsal-based ulnar splint does not pinch or impede grasp. Radial and ulnar polycentric hinges located at MP joints on the ulnar splint won’t impede flexion or extension. Splint is padded with malleable finger rings that can be individually shaped to fit each finger. Ulnar splint is not made with natural rubber latex. The patented polycentric hinge allows full flexion (bending) and extension (straightening) of the fingers. Softly cushioned finger stays can be opened and closed to make this splint easy to put on and take off even if your fingers are swollen. Ideal for use following MP Arthroplasty. Moderate Control. Available in Left or Right.
