Will MRI Localize the Site of Back Pain? – Epiduroscopic Study Suggests No – What this means for Insurers

Cases of chronic back pain with or without non-radicular leg referrals (in leg but not classic sciatica) were examine clinically, with MRI and by using a “keyhole” scope instrument in the spine called an Epiduroscope.  Scoping and probing area during scoping could reproduce spine and leg pains in 87% of cases. MRI concordance was only 3.5% (flip your coin – you’ll be more accurate).

In the previous century it was said that 85% of back pain is not diagnosable. Now that is changing. Scopes put in the spinal canal can find areas of redness and neurovascular growth that reproduce the patient’s pain in both back and leg when probed. Clinical exam and MRI just don’t do well in comparison.

  • A significant cause of back pain seems to be cracks that occur in the disc near where the spine is. These cracks become inflamed and cause growth of painful neurovascular tissue that can extend into nerve root canals.
  • Epiduroscopic exam can pick up the areas of thickening and redness – probing these areas can reproduce the victims pains.

Clinical exam and MRI were not at all helpful in delineating the problem or the level the problem is at:

As you can see, on epiduroscopy, L4/5 was the primarly level of problem; For MRI the primary level was “None”. The concordance of MRI with epiduroscopy was 3.5%.

 addendum – The dural can be a very pain sensitive structure and merely injecting fluid into the epidural space can be painful:

Comment – Victims who are made victims twice over by having to deal with SGI (our provincial insurer) are told that there is nothing significant the matter with them when their MRI’s are negative. I recently had a subject that had bad neck pains referring to shoulder blade (obviously facet, nonetruded disc and now epidural components) . He also had such a bad thoracic outlet syndrome  that he could not raise his arms in Roos postion more that 10 seconds without getting numbesss, he his arm was  obvious red  and the skin temperature lower. He was still told there was nothing significantly the matter with him. [oddly they did say he could apply for Canada pension].  It  is getting so  nauseating obvious that they are playing the game hear-see-say no evil that I am certainly sick. This is all done with legal protection from all damages and anonimity. How to deal with this situation is another matter… sac michael kors outlet sac michael kors outlet

    I’m curious if anyone has had this Epiduroscopy to locate back pain. I’m 3.5 years post accident and there saying that there is damage between l4/l5l5/s1 but not 100% sure what . The pain is bad and I want out. Does this or can it make things worse . How effective is it and is it possible that finding out won’t make a difference in regards to surgery? My doctors never even suggested this as an option. I live in Canada and I’m 26 . Had MRI’s, epidurals, exams X a million, pills (they make me crazy or high) and there going to do some kind of testing on facette joints and possibly the nerves? I just want to be better, find out what’s going on and stop seeing a retarded amount of doctors. Hope someone has answers. Thanks in advance
    Epiduroscaopy is a very new technique; it is not readily available anywhere in Canada that I know about. Anyone who really wants it would be best to go to the group in Texas that helped pioneered it: [unless they are in Germany where Schutes is : http://books.google.ca/books?hl=en&lr=&id=LOfrumnBXz4C&oi=fnd&pg=PA1&dq=HEAVNER+epiduroscopy&ots=yL_OnM8WQo&sig=GdA8eHq0GFPEp7m-dIm9CsofzmA#v=onepage&q=HEAVNER%20epiduroscopy&f=false

    Here is a power point discussion of the texas group’s results:
    Sounds like it gives 12 months of relief anyway.
