For Lateral Instability With Full Range of Motion
Use the SIRIS™ Lateral Support Splint to correct lateral deviation and block hyperextension of a joint, while allowing full flexion. The lateral support, which is the fulcrum point of the splint, is always placed on the side opposite the direction the finger is deviating. For example, if there is ulnar deviation of the finger, you should order a splint with support on the radial side. If the finger is bilaterally unstable, request a splint with support on both sides. This splint can be worn on any of the IP joints of the hand.
