question: I had a CT last week I m s/p spinal fusion L5-S1 with rods, cages and screws. My CT report said this. Mild DDD seen at L4-L5 with mild diffuse disc bulge and degenerative facet changes causing minimal central stenosis . Post surgical changes seen at L5-S1 with resection of the posterior elements. So my question is do I have another herniated disc?
