3PP Radial Hinged Ulnar Deviation Splint

Product FAQS

My fingers are really tight. Which ulnar deviation splint should I choose?

If your fingers are quite tight but still movable at your large knuckles, the Radial Hinged Ulnar Deviation Splint is more likely to be effective than the lighter weight Polycentric Hinged Ulnar Deviation Splint.

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 Radial Hinged Ulnar Deviation 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.
