Pain
Syndromes and C-Spine/Foramen Magnum Cord Compression - Two-Year Experience

At
the September 1997 seminar sponsored by the National Fibromyalgia Research
Association, I learned of the connection between fibromyalgia/CFIDS/chronic
pain, and cervical spine/foramen magnum compression abnormalities.
Since that time I have done thorough neurological examinations on nearly
all patients referred to me with chronic pain.
Total
patients seen with pain syndromes = 335, and those evaluated neurologically
= 271. Of the 271, neurological abnormalities resulted in 144 recommendations
for C-spine MRI, done according to a special protocol to assess true canal
diameter at each cervical level. Axial cuts were made through the
foramen magnum in a plane parallel to the foramen magnum to assess true
cerebellar tonsillar ectopia. Eighty-eight such MRIs were done.
Almost all were interpreted by the UW radiology staff as normal, as showing
only minimal disc bulging, as showing DDD/DJD, or mild thecal sac effacement.
Only one was read as showing a Chiari malformation, and 7 as showing frank
stenosis of a moderate or severe degree. In contrast, 79 of these
MRIs were interpreted by the author and by Dr. Dan S. Heffez: 12
– normal, 16 – minimal abnormality, 18 – significant cerebellar tonsillar
ectopia, 21 – significant stenosis, and 24 – stenosis and ectopia.
Thirty-nine patients were seen and evaluated by Dr. Heffez. Twenty-three
had at least one operative procedure done, and three were not considered
surgical candidates. Of the remaining 3, surgery was recommended
for 11, and follow-up with possible surgery for 2.
