L4-L5 in lower back. My surgery was end of oct and I just went back to work light duty. I'm feelin pretty gud considering it was a fusion. I'm 33 so my dr said my age, health an physical stature play a big part in a speedy recovery. I go to surgeon end of February to have X-rays done and see how the bone is growing/healing. He said it is 8-9 months for complete healing of the bone graph. First month after surgery was the hardest. By mid December I was gettin around ok. I have a back brace that needs to be worn until end of February. Only time it can come off is if I'm lying down. I've been strict with wearing it and its def helping.
