Has anyone had this type of fusion or heard of anyone having it. My doctor is doing the soft stabilization(flexible rods) above the L4-S1 TLIF to hope to keep the L3-L4 disk from degenerating even more and sort of dispersing the pressure amongst more levels than just the one above the fusion. I have already had 2 diskectomies and laminectomies in the past year with continued herniations and severe DDD. Since I am active and relatively young (40) my doctor is trying to better my quality of life!! Just trying to get more information on it. I think it is a fairly new procedure.
