Forged from heavy wire stock for strength and durability this splint is specially designed to immobilize the IP joint and stabilize the MCP joint while still allowing movement. This splint was designed when I developed bilateral trigger thumb in spring of 2024, I needed something that would immibilize the IP to stop it from clicking while still allowing the range of motion I needed to work.
There is also a fully immobilizing version with CMC support added on, which is what I slept in to keep all of the joints immobilized and allow them to rest.
Please select your US ring size, metal choice, and hand the splint is for from the drop down menus and fill out the required fields. For this splint you would want to take the length measurement from the inside of the IP joint to web of thumb with the thumb held straight, rather than bent as when measuring for the hypermobility splints.
This IP joint part of this splint is adjustable within about a half size larger or smaller and the length can be adjusted to ensure the most comfortable fit.
Shown with additonal radial support, which is available at the bottom of the splints page. This splint style does not require a chain, it is held in place by it's grip on the IP joint.

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.
