I did that to my left thumb metacarpal my first season of skiing - trying to Wedln in heavy wet thick gloppy snow. That was the last time I tried doing Stein's Mambo...
Anyway, I spent six weeks in a cast, then a couple of months regaining muscle strength - after a week or so of immobility, your muscles just atrophy to the point where there's no strength whatsoever. I didn't elect for surgery, the doc just immobilized it and let nature take it's course. I think the recovery is a bit faster with the surgery, but your physician can telly you more.
I can't say it put much of a crimp in my life - ski season was basically over (late march in southern Michigan) and I just waited until May to start sailing. I didn't miss any days of work for what that's worth. I broke my left thumb and I'm right handed - if it's your main hand, it could be more of a problem. .
Interesting factoid: the same day I broke mine, my wife's colleague's husband had the same injury - he lives in the UP and didn't want to miss any skiing so he brought in his ski poles and had the doctor form the cast around the pole so he could keep skiing. I wasn't that much of a die-hard back then, but at this point I might. Of course, not every doctor would comply with this request - things are different in the UP.
Good luck with it. It's really not much of a setback in the greater scheme of things.
