First off, glad you are alright.
Second, I don't know enough about insurance claims on bikes. Some of the other guys will have the experience. I'm assuming if you claim it and buy it back, then insuring the bike may be difficult depending where you live. I know paulpud and some other guys have frames lying around. Talk to them. It may be a whole helluva a lot cheaper and less of a headache to buy a used frame and just fix the bike yourself.
