A therapist favorite! The Comfy Splints Hand Thumb Orthosis is uniquely designed to support the thumb without stressing the web space between the index finger and the thumb known as the "Thenar Eminence". Soft straps accommodate sensitive skin, edema and fragile skin. Soft Neoprene in all Comfyprene. Fully and easily adjustable at all joints to make a custom fit without the use of tools or heat guns. Side wings prevent ulnar/radial deviation. Ambidextrous.
