Oh my goodness, I feel for you. Four years ago, on the first day of the Christmas holiday I toppled over ice skating (I was actually been standing still at the time, not racing around) and pulvarised my wrist. Surgery, two plates and a SG$15,000 bill later I found life was liveable but not without some help - my 7 yr old daughter had to learn to do up my bra - I'm not sure who was more embarrassed, her or me! And chopping up tough round things like onions or potatoes was impossible - not the chopping bit but the holding down of the veg.
The upside to the metal work though, is that 4 yrs down the line, my bionic wrist is much stronger than the other one in terms of eg: carrying shopping bags. But I really recommend having some physio afterwards; my policy allowed me to have quite a lot and I have almost full movement back. My mother had a similar break with no follow up physio and has very much more limited use. The only thing I really can't do any more is my Queen of England wave - not that there's much call for that around here!!
Really good luck with the mending process.
