OK, thumb sprains occur when you're extentended hand hits the snow and your thumb gets bent back. If you don't let go of the grip, your hand won't open, and you probably won't injure you're thumb.
the second way a thumb sprain occurs, is from incorrect pole strap use, as Telerod stated.
Pole grabbing 101.....
Take your poles and grip it lika a newbe would, putting your hand through the strap and grabbing the grip. Then extend your hand past the top of the grip, like if the pole got stuck and your hand kept moving. If you gripped the pole and strap the wrong way, your thumb stays in the loop of strap and will get bent back.
Now, grab the pole the correct way. Put your entire hand up through the loop of the strap, then bring your hand down onto the grip, grabbing both parts of the strap under your hand. If your polestraps were buckled correctly, both pieces will sit flat, and also sit flat around your wrist. NOW, drive your hand past the top of the grip again. If done correctly, the strap will go up your arm without catching on you thumb. The strap will stop smewhere on your jacket, where your arm is strong enough to either break the pole free, or spin your body around without hurting anything but your pride, avoiding the epin around is another lesson.
So, maybe Telerod isn't so full of BS.......
PS. I hope poles aren't passe, cause I couldn't resist those $225 poles from S&C and I was hoping to be stylin this seasonhttp://www.steepandcheap.com/steepch...84&id=NSbnMLmy
