ABSTRACT:
A device for immobilizing the thumb, hand and wrist of an individual is a shell formed of an integral piece of semi-rigid material having portions shaped to receive the upper forearm, hand and thumb. The device is easily slipped on and off by means of expansion of a longitudinal opening which bifurcates the upper side of the device. The bottom and top sides of a region of the forearm portion are flat to prevent rotation of the individual's forearm within the device. The forearm portion is also shaped to accommodate the protrusion of an individual's ulnar bone on the upper side of the wrist. The diameter of the thumb portion is easily adjustable.
