Abstract: A wrist-forearm-elbow anti-rotation support system and process that do not require a hardenable material. The system includes an orthopedic support such as a wrist-hand orthosis, wrist-hand-thumb orthosis, joined to a bottle-shaped forearm wrap with opposed flaps formed into a clamshell. Proximal elbow flaps include a center elbow region that extends from the proximal end of the forearm wrap. Attaching straps and/or cross straps extending from the proximal elbow flaps attach to the forearm flaps and may crisscross. Hook and loop fasteners extending from the distal edge of the forearm wrap attach the forearm flaps.
