Re: 3 level spinal fusion
My surgery was 2.5 hours, and it was only the L5-S1....you can call the hospital and ask how long your doctor booked the operating room for. Normally doctors book however long they feel they'll need to do the operation + 1 hour in case of complications (or at least that's what I've been told.).
Best of luck with your fusion!
