I had 2 lumbar spinal fusion surgeries in 2003. It was L-5 and I had spondylolysis. The ortho doctors said it was a deformation in growth. I just started seeing a new Ortho Dr. who told me there is no scientific fact to prove that. He asked me if I played Sports when I was younger and I told him yes. I told him all the sports I played and I included softball period he asked me if I was a picture and I said no, but he thinks that may have been what caused my disk to have done what it did to give me spondylothesis. Anyone else ever here that?
