Product FAQS
How do I know what size to buy?
To size for the splint, put a ruler or measuring tape on a table and rest your hand on the ruler at your big knuckles.
Try to keep your hand relaxed and don’t press it flat to the surface. Measure across the big knuckles from the outside edge of your index finger to the outside edge of your pinky finger.
Will my fingers stay straight when I take the splint off?
While the Polycentric Splint will hold your fingers straighter when you are wearing it, it is unlikely that it will correct the deviation once it is removed. While there is no research that shows splints can stop the progression of deviation, it has been shown that a properly fit splint can help improve hand function.
How much should I bend the stays?
When bending the stays, gently curve them around your fingers. Be careful not to create sharp bends in the stays, as this will lessen the life span of your splint.

Quite uncomfortable and does not actually separate my fingers or help them from pronating. Expensive experiment.
Jane –
I had a PT make two different splints for me which did not work. In her defence, she was trying to make a non-obtrusive, non-limiting device that was effective yet comfortable. Neither worked. This one works great. While it does not stop the ulnar deviation totally (it would probably take a cast to do that!), it really does limit it and I feel like it does keep my index finger from "collapsing" so readily. It took some "tweaking" to soften the edges against my skin. (handy spouse with a heat gun and some talent). I wear this around home most of the time and at night, and am typing with it right now. I don’t wear it in public much only because I don’t want to draw attention, and I do most of my heavy work at home anyway. This is a great product especially for the price.
