I don't disagree that prosthetics have come a long way, as we can see by some of the amazing things that wounded soldiers do after returning home and being fitted with them.
This situation would be as much, or more about the mental state for me. If you have some disease where the diagnosis is amputation of something, you at least have the chance of being told about it and in some way prepping for it, and it will often be one appendage versus the four main ones all at once. Even if you're in an accident like a car crash, you may wake up to find a limb or two gone, but your mind at least had the chance to prep for it in the split second before the crash -- it knew you were about to be messed up.
In this case, she would have been completely unprepared and unsuspecting. It would totally freak me out to go to sleep tonight and wake up tomorrow with no hands and no feet. I might get over it in time, but the initial shock would be a nightmare.
