I am having an ALIF with cages (L-4 to S-1) and then I get flipped over for screw fixation and rods. Is that a 360?? And is it more or less painful than an open posterior fusion with cages, rods and screws. Am having surgery in one week and am starting to get really uptight and scared of the whole deal. Anyone know approx how long until I can sit for a couple of hours and approx how long until I feel like going out on a Sat night socially? Thanks for all your help. This site has kept me reading for hours and love the info!!
