CMC Thumb Spica Splint Core Products


SKU: N/A Categories: ,

The CMC Thumb Spica Splint provides comfortable and firm support, stability, and compression to help relieve pain and discomfort associated with injured or aching thumbs. This splint significantly reduces motion of the Metacarpophalangeal (MP) joint, Carpometacarpal (CMC) joint, and Ulnar Collateral Ligament (UCL) to help stabilize the thumb, prevent hyperextension, and promote healing. Our design features an adjustable compression pad for true customization.

Unlike most other thumb spicas, the CMC Thumb Spica Splint covers the entire thenar eminence to provide ultimate support and stability. This thumb splint provides CMC stability during pinch & grip motions without impeding other joint movements. Ideal for: pre-op, post-op, minor and major injuries, CMC pain relief, stable fractures, trigger thumb, arthritis, soft tissue injuries, strains, sprains and other conditions.

The removable 6″ malleable splint provides comfortable positioning and helps stabilize the thumb. Made from aluminum, the splint places the thumb in a neutral position and allows the thumb to rest by minimizing motions that may aggravate nerves, tendons, or ligaments. Use the additional strap to minimize excessive thumb movement and further limit ROM.

The included padded strap applies pressure to irritated muscles, tendons, and ligaments of the thumb and wrist to help ease pain and discomfort. When used in combination with the padded strap, this splint also helps relieve symptoms of carpal tunnel syndrome (CTS); simply place the pad on the Thenar muscles or below the CMC joint. Also ideal for; osteoarthritis, arthritis, tendinitis, trauma to thumb, rehab sprains, and other soft tissue or repetitive stress injuries.

The low profile design allows full use of fingers and the adjustable thumb and wrist closures offer easy application and a custom fit. This splint is designed to contour to the natural shape of the wrist and thumb for increased comfort.
