This seems odd to me.... I had ALIF on L5 S1. The doctor did an MRI about four weeks after surgery. The MRI report talks about L5S1 however, I had a CT Scan last month and the report only talks about surgery at L4-L5. I don't understand this at all. My pm doctor looked at the report and took his own xrays this week, he says that he needed to make sure the surgery was in fact done on L5S1. He says that I have a transitional vertebrae (which I knew) and he believes the radiologist read the ct scan wrong. How can I make sure of this? One says one thing one says something else entirely. I still have the same pain in my back, along with nerve pain in my right leg. The ct report says that L3 L4 is now bulging, but it was not noted before surgery. The only thing the Ct scan says about L5 S1 is it has decreased disc height.
I know that fusion surgery can cause problems with the level above surgery, but if surgery was done on L5 S1 shouldn't the problem be with L4 and not L3? That would have been the next level up.
