The Swede-O Universal Thumb Spica provides comfortable support and gentle compression to help relieve pain and discomfort associated with injured or aching thumbs. This brace significantly reduces motion of the Metacarpophalangeal (MP) joint, Carpometacarpal (CMC) joint, and Ulnar Collateral Ligament (UCL) to help prevent hyperextension and promote healing. The 6" malleable splint provides comfortable positioning and stabilizes the thumb. Made from aluminum, this support places the thumb in a neutral position and allows the thumb to rest by minimizing motions that may aggravate nerves, tendons, or ligaments. The low profile design allows full use of fingers and the adjustable thumb and wrist closures offer easy application and a custom fit. The material is soft and comfortable against the skin; bilateral design fits right or left thumb. Measure evenly around wrist joint- OSFM 6" - 11". Regularly hand wash cold, mild soap, and hang dry; close all hook and loop fasteners to prevent damage to other fabrics.
