What is fusing the back if the front is already fused
I have 4 fusions in my neck and 2 in the lumbar area, The Dr. wants to try removing the hardware from the front of my neck because the screws are coming loose and going into my throat. He said he wants to fuse the back of my neck now. I was thinking all they could fuse was where the disc was so I have no idea what he is talking about. Anyone know what he is talking about.
