RF - very sad to hear of your misfortune. Heal soon!
If not for the clavicle, you could probably be skiing again in a week or two. You'd be yelping like a small puppy every time you hit a small bump, or rode a bumpy chair lift, but you'd be skiing. (Know from experience.) An elastic ACE back brace will help "hold in" the ribs when you come back.
Calvicle could take 10-12 to completely heal, but you might be skiing at 6-8 if your doc allows. Right in time for nice spring conditions!!
P.S. a good joke hurts worse than skiing! Hide from your funny friends! And whatever you do... don't sneeze.
