Ouch!
FWIW, I shattered the Radius and the Ulna in my left wrist 10yrs. ago. There are two products that I don't ride without anymore. One is a EVS wrist brace and the other is a Boyesen Flex Grip. These two products have let me continue riding. I've tried other braces but all hinderd my grip of the bars. (The No Gomer in the web site looks to be a pretty good brace, kinda wondering about the thumb part though. ) The Flex Grip allows the wrist to rotate just enough in hard landing that I don't rejam the head of the Ulna (which is the part of the wrist that shattered).
Good luck, I hope this helps.
