Can one survive alone with just crutches and no caretaker after the surgery? I don't live at a wheelchair accessible home, and I am wondering if I can do this surgery with the Precise 2 nail and go on in the lengthening phase with just crutches and no caretaker (I don't plan to lift heavy things, I'd occasional ask a friend to come over for help). And can I do all of this if the Stryde nail comes back?
