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.
