I'm very sorry to hear that. Have you sought medical advise, including physical therapy to re-build?

your hand/wrist injury raises an interesting thought in my mind, what if your out in the woods and suffer an injury that renders both hands useless (assume your lost, night is falling etc. and you can't just walk out)? think of the simple things you could not do like open your pack, dial a cell phone, make a fire/shelter etc. Similarly, one of my fears since I typically go out alone is to lose my eyesight (branch whack or something) -then you better have some luck on you side. Ever tried to setup a shelter blindfolded?
