    You do have a dilemma if you have continued nerve pain after a successful cervical fusion as well as multiple posterior decompressions (foraminotomies) that were unsuccessful. It seems to be the case if the current CT scan demonstrates solid fusion with continued foraminal stenosis. The big question is what is continuing to cause your pain. Do you have pain due to continued compression of one or more nerves or do you have a chronic pain syndrome where the pain generation is multifactorial and no mechanical source of pain.

    If there can be identified a nerve that is chronically compressed (through a diagnostic SNRB-selective nerve root block), then you possibly have a mechanical answer to your pain that can be corrected. The SNRB does not identify why the nerve is causing pain but does identify that the nerve is causing pain. Whether the nerve is chronically injured or compressed is not identified by the SNRB. That is, decompressing the nerve surgically may or may not yield pain relief.

    The spinal cord stimulator can be effective to reduce pain but there is no patient I know with a stimulator that describes this device as a miracle. Most will say that they “are better” but not “cured”.

    Good afternoon Dr Corenman,

    CT Scan states:

    There is straightening of the cervical lordosis. There is osseous signal intensity noted across disc space. There is good posterior decompression of the spinal canal. The C5-6, C-6-7 and C7-T1 disc space levels demonstrate osseous signal intensity course the disc space consistent with osseous fusion.

    There is anterior fusion utilizing anterior plates and vertebral body screws there are bilateral pedicle screws with vertical stabilizing rods from C5-T1.There is wide laminectomies with good posterior decompression of the spinal canal. The neural foramina are patent.

    to recap: I have a solid fusion per my CT Scan, my cervical MRI states foramina stenosis, disc bulges effacing epidural compartment and thecal sac, multilevel anterior-posterior spinal postoperative changes, facet joint and uncinate exhibit some sclerosis.

    Questions:

    1)Should i now focus on the facets or discs in the upper thoracic spine?

    2)Request a selective nerve root block of the cervical and upper thoracic spine?

    3)Avoid radio frequency ablation of the cervical spine and thoracic? I’m not sure on this one since I have instrumentation to T2. Does this mean the facet shouldn’t move and therefore no pain?

    Thanks

    Your reports are somewhat conflicting as your CT scan notes; “There is wide laminectomies with good posterior decompression of the spinal canal. The neural foramina are patent”. This means that there is no bony compression of the nerve roots (a patent foramen is a wide-open foramen).

    This then compares with “my cervical MRI states foramina stenosis”. If you have foraminal stenosis that is not identified on CT scan, either the MRI is over-read (there is no foraminal stenosis but the MRI is mis-read) or there is cartilage and ligament compression present that does not show up on the CT scan (but will be demonstrated on the MRI).

    Your pain generators are not yet defined and it will take some work to try and discover what is causing your pain. Solid fusion eliminates the fused segments as a pain generator but the levels below (disc and facet) can cause local pain that radiates into the lower neck, shoulders and scapulae. Selective nerve root blocks (of the already fused levels that demonstrate foraminal stenosis) can indicate pain generation but as I said before, a positive block does not mean the nerve pain can be cured by surgery. You might need facet blocks or even discograms.

    If you have instrumentation to T2, I will assume that you are fused to this level and you don’t have motion, therefore pain (disc or facet) from the levels above the T2 level.

    Good morning Dr Corenman,

    I really appreciate your feedback and it has been really a great blessing getting feedback from you. My dilemma has gotten worst. My EMG was performed yesterday and was told by neurologist that I have C3, C4 and C5 nerve compression. A review of my CT Scan images showed foramina narrowing at C3, C4 and C5, she not sure what the radiologist was looking at. Said CT scan was under read and agrees with MRI.

    The big dilemma is radiologist findings are different then neurologist, how? second can cartilage and ligament compression cause EMG findings? I called a couple of local imaging centers today and was told they don’t provide 2nd opinion services. I’m exhausted from this back and forth. All I want is relief. Have a great weekend.

    The EMG is not a great test for nerve compression in the higher nerve roots (C3 and C4) as these have poor connection to the muscles and readings can be too broad. Now, if you have changes in the deltoid muscle (shoulder muscle) that are identified by the EMG, that is some real evidence of problems.

    I think you can get another radiologist in the same group as the first one to “overread” these images if you have a conflict between the neurologist and the radiologist. Maybe a new surgeon consultation is now required.

    Hello Dr. Corenman,

    Echoing everyone else’s respect and appreciation for your time!

    About 2 years ago I had four cervical discs (C3-7) replaced with ProDisc-C Nova units. They surgery and recovery went very well (yay physical therapy and personal training) and I’m able to do just about everything a 50-year old guy should expect including occasional fun with dirt bikes (of course I wear all the gear including a neck brace). Multiple check-up X-rays show that the devices are still perfectly in place and overall I feel way better off than I was pre-surgery. I have no regrets, and have recorded a number of post-surgery journal videos to maybe help others.

    Anyway, about a year after surgery I noticed that bending my neck backwards to the left or right caused what feels like (facet?) nerve compression into my shoulder, underarm, lower biceps, forearms, wrists and fingers. I take a prescription NSAID and Ibuprofen daily to reduce swelling and it does seem to help a bit, but I feel like there’s still something structural going on. It seems to make me more prone to repetitive stress in my hands and arms – like they’re always under some nerve flexion. I am imagining that C7-T1 or T1-T2 might be under “stacking” compression particularly on the facet joints or the foraminal canals. Does this sound sensible, or would you think it’s something else?

    It hasn’t been bad enough for me to start the whole MRI/CT/XRay and consulting process again, but I should probably set some limits on when to engage neuro or ortho consultation. Any opinions would be most welcome!

    Thanks in advance,
    Scott in Columbus Ohio
