Combination Thumb MCP/CMC Splint

PriceFrom $100.00
  • All metals we use are 100% lead and nickel free hypoallergenic pure metals so they will not tarnish, rust, or lose their color and oxidize the skin. You can read about the variety of metal choices we offer below!*

    Nickel Free Stainless Steel- We only use high quality 430 stainless steel that is certified to be nickel free from the manufacturer. This type of steel has a slightly higher level of chromium than other types of stainless steel instead of the nickel that would typically be alloyed in. It has good corrosion resistance so will not pit, rust, or oxidize.

    Sterling Silver- Sterling silver is an alloy of 92.5% fine silver and 7.5% copper. The copper is necessary to strengthen the metal, as fine silver by itself is far too soft to be used in any jewelry application. While it's very rare, some people can react with the copper content and find their fingers oxidized. Sterling silver will be kept shiny by the natural oils in your skin from wearing it, but if it has been put away for a while may tarnish. If this happens, a simple jewelry cleaning cloth will remove the tarnish.

    Titanium- We use 99.9% pure Grade 2 titanium. This grade of titanium is softer that Grade 1 so that it can be hand worked into splints. Titanium is extremely lightweight and is an excellent option for those with sensory issues. Titanium is also the best choice for those with MCAS or severe metal allergies due to its hypoallergenic nature. It is very rare for titanium to cause a reaction.

    14k Gold Fill- We offer 14k Yellow and Rose gold filled options. Gold filled is similar to gold plated, but with a much thicker coating of 14k gold over a brass or copper core. This gives assurance that the gold will wear well, without flaking or peeling off like plated and having a more reasonable price than solid gold.


    *Please note that different metals have different tensile strengths so to ensure each splint has adequate and proper support not all sizes will be available in all materials.

  • This splint requires three measurements- the ring size, the length, and the circumference of the wrist.

    To find the ring size, using your preferred sizing method measure directly around the thumb IP joint as shown in the last picture.

    The length measurement should be taken from the web of the thumb to just under the CMC joint as shown with the vertical line in the last picture.

    Using a soft taper measure you would take the wrist measurement around the base of the hand.


    Further sizing instructions with graphs, charts, and a free printable ring sizer are available on the sizing page.
