OP:
i get skiers thumb all the time. i hear if you tape your thumbs when you go skiing it will reduce the risk. i could see it working considering my thumb feels almost perfect when i hold it and put it under compression. ive yet to try it yet though, dont know why.
other than that, if it happens a lot, dont put your pole straps on. the reason it happens is because you fall with your poles in your hand (well thats how skiers thumb originally starts). the grip pushes on the webbing between your thumb and index and pulls some shiit (thats why it happens in the thumb and none of the other fingers). so if you can drop your poles before your hand hits the snow/ice, you shouldnt get it as often.
