That's ironic because I broke my scaphoid as well in November. Super unlucky/lame fall. I just got my 2nd cast off yesterday after 2 months of being in one. I skied a decent amount and still charged groomers and pow. I skied some park but I've been taking it easy in there. Now I'm in a removable splint/cast for another 5 weeks.
I'm curious, what have you been using as a mitten? I use a wool sock and oven mitt over that...nice and toasty!
OP, don't ski with a collar bone or something that serious. But if it's a hand, wrist, finger, shoulder, you should be fine as long as you're a smart and good skier. You have to be more cautious of your skiing and others, and make sure if you do fall, don't let anything interfere near your injury.
