I had 2 level ACDF surgery in 2009. Fusion of C3, C4 and C5. Severe cervical disc disease, very bad neck and shoulder pain, severe balance and gait issues which were all greatly reduced by the surgery. But now I've developed stenosis at C6 and C7 with a flattened cord and completely effaced cerebrospinal fluid at C6 and C7. The spinal canal diameter is 6 mm at C6 and C7. This info from an MRI last month, and I have an upcoming appointment in a little over a week with the same neurosurgeon who did my 2009 surgery. The MRI also noted "degenerative changes in the bone marrow above and below the fusion site, however, there is no bone marrow edema." "Ferromagnetic artifact" at the fusion site interfered with evaluation of the bone marrow signal at the fusion site." Has anyone experienced what appears to be fusion caused bone marrow degenerative changes?
