I have struggled with lower back pain for the past year. Recently I had a discogram. It showed that I have a level 4 tear on my L4/L5. The Dr. wants to do surgery. A fusion. I have seen two differnet surgeons. One wants to go in from the front, the other from the back. Both Dr.'s have given me only a fifty-fifty chance of feeling better. I really do think I want to have the surgery. I have to choose surgery or live with the pain. I can no longer live like this. I have five young children to take care of. Has anyone had good or bad experiences with the ALIF surgery on their L4/L5?
