I feel bad for your situation. If I were in your shoes, I wouldn't think of trying to shoot until you get the go ahead from your doc, trying to do otherwise might eliminate you from bowhunting (no matter what kind of bow) in the future altogether, and that would really stink!
I'm putting myself in your shoes, thinking what I would do in your situation. Well, it's time to start studying. I'd fill my time with reading everything imaginal about bowhunting, then I'd re-read it. Then you could get into videoes, hunting videos, shooting videos, shooting form, etc. Repeat as often as possible, as repetition is key. Also, as you said, be the camera guy whenever you can, you'll be right there in the action of things.
Scouting. You can scout year 'round. Do this consistantly while you are laid up and you will be better prepared than your able bodied hunting pals when you get healed up.
How about trail camera's? I've never gotten into them, but that could be a fun way of "getting" your deer over and over again.
Above all else, listen to your doc so you can hunt in the future.
