A
lmost every Doctor of Chiropractic that has been in practice for 8-10 yrs. or more has experienced the chagrin of treating a patient for a subluxation and afterwards having them discontinue care, only to find out later that the patient was doing very well after a surgical disc operation.  After experiencing 1 or 2 of these embarrassing scenarios, we may come to realize that there may be more information involving a subluxation than meets our chiropractic eyes.
 
subluxvsdischerniation4This embarrassment of missed diagnosis should never happen to a Doctor of Chiropractic. A DC should and can be in a position of being CORRECT in his/her diagnosis, before a patient has an operation for a herniated disc. If a DC is not correct, not only does he/she lose credibility with their patient, but their reputation is harmed. Imagine, if nearly all DCs have one or two of these missed diagnoses periodically, our entire profession loses credibility on a large scale. 
 
One of the many definitions of chiropractic that has stood the test of time states that “Chiropractic is the art, science, and philosophy of locating and correcting nerve interference, without the use of drugs or surgery.” Notice that it does not say what is causing the nerve interference, nor does it say what is used to correct the nerve interference or how it is to be corrected. This allows the chiropractic profession to have great latitude in describing what we do, but that does not excuse us from making an incorrect diagnosis.  
 
In order to understand how to correct spinal pain we MUST have a correct hypothesis of what is causing the nerve interference. Many hypotheses appeared in the chiropractic profession, the most popular of which has been the subluxation (or bone out of place) theory. This idea was accepted broadly by nearly the entire profession. Not so by medical surgeons. It is only common sense to them that when a chiropractor works on a patient and proclaims that the cause of the patient’s pain is a SUBLUXATION, and a surgeon operates and resolves the patient’s pain by removing the disc bulge, WE LOSE CREDIBILITY.  
 
However, the DCs continue the drumbeat to remove subluxations that they analyze to be displaced, a missed diagnosis. 
 
After the subluxation theory 60 years ago, along came Nimmo’s pressure theory.  Then came the “fixation theory” that theorized that “fixations” were the cause of the nerve interference.  Kinesiology then came into being proposing that imbalance of the muscular systems caused much of the nerve interference. Also there were reflex techniques, full spine techniques, cranial-sacral techniques, and many others. All had some success, but they had obscure, vague, ambiguous, and even conflicting hypotheses of what the actual mechanism was that caused the nerve interference or pain. And when it came time for a report of findings, it was difficult, to say the least, to convey understandable causation to the patient. In light of all the new information that has been revealed in the present-day healing world, the profession may need to come to grips and accept a new paradigm in order to make progress and grow.
 
Some of these theories appeared in chiropractic simultaneously, and resulted in much confusion in the profession. Chiropractic must come to the realization that, along with slight subluxation, herniated discs play a major role in compressing the SNR to cause spinal pain. 
 
A subluxation, which is defined as a vertebral displacement less than a luxation, can occur when extreme motion takes place in the spine that is beyond a motor unit’s normal physiological range of movement. And if this movement is in forward flexion of the spine, the increase in pressure will be concentrated on the front of the discs’ nucleus pulposis (NP). If this pressure is great enough it can suddenly thrust the NP posteriorly, breaking through many of the internal annular rings of the annulous fibrosis which then could bulge the outer rings of the disc into the intervertebral foramina (IVF) space and exert pressure on the spinal nerve root (SNR). (The majority of disc herniations are internal in nature, similar to a bulge on an auto tire or an inquinal hernia, where the outer skin still contains the internal ruptured parts).
 
We now have a subluxation and a herniation of a disc occurring at the same moment. Not all subluxations and disc herniations occur this way, some disc herniations can occur

without a subluxation, i.e. a subject can jump down from a 10 ft. wall and herniate a disc, and a  person could have a subluxation without enough force to cause disc herniation.  
 
However, there is strong evidence that many disc herniations are associated with a subluxation. The frequency of which could be very high. Could this be one of the most prevalent causes of spinal pain? If we conclude that a bulged disc is in fact causing pressure on an SNR, shouldn’t we as DCs include this in our diagnoses? If we conclude that a bulged disc is in fact causing pressure on an SNR, shouldn’t we as DCs include this in our diagnoses?
 
So, it’s not SUBLUXATION VS. DISC HERNIATION – it’s subluxation WITH disc herniation. This is a change in the chiropractic philosophy as to the cause of nerve interference that, if adopted, could give real relevance to our profession. Why should we adopt this change? The answer is, of course, that there is OVERWHELMING clinical evidence that in most cases of SPINAL PAIN, it is the bulge of the disc that presses or squeezes the SNR, and not the bone pinching the SNR. 
 
A Hypothesis of Disc Pain Causation by Clinical Evidence
 
Here are some examples of strong clinical evidence that a high percentage of spinal pain is caused by subluxation/disc herniation. 
 
1. MRIs have proven that there are frequent, multiple disc bulges in most spines. Even though some of them may not be symptomatic, they can become so as people do repetitious bending while doing normal daily activities. Multiple spinal flexions may gradually increase the size of these dormant bulges.  They can then begin to touch the SNR, becoming symptomatic. 
 
2. Most histories of patients demonstrating back pain occur when the subject is in a forward bent position, i.e. lifting a box over other articles in the trunk of a car, bending over to pick up a heavy item, picking up a pencil off the floor, bending over doing toe touches, or as simple an action as lifting the corner of a bed mattress to tuck in sheets. It’s easy to visualize what is happening within the spinal disc. 
 
3. Thinking about all the above activities that may cause back pain, the idea of the disc placing pressure on the SNR reasonably begins to dovetail to the subluxation/disc protrusion scenario. (Bending first, nucleus pulposis of disc suddenly slipping backward, second = sudden cause of back pain). Of course, it doesn’t always occur suddenly, the disc NP may slip backwards gradually. 
 
4. People that stand constantly in their job have a high incidence of low back and leg pain because discs tend to flatten with many hours of weight bearing. This can cause circular peripheral bulging of the disc and place pressure on the SNR.
 
5. For the same reason overweight individuals experience frequent disc, back and leg pain. 
 
6. Lumbar spinal decompression by expensive machines is adding strong evidence to the credibility of disc herniation, claiming results up to 80%. If subluxation was the ONLY major cause of back pain, I doubt if decompression results could be so effective, for they do not claim to replace the subluxated bones. However, decompression could tend to draw in or suck in the disc bulge or protrusion.

Chiropractic first, medicine second, and surgery last.


7. Very much credit must be given to Dr. James Cox for his persistent teaching of the herniated disc theory over 30 years ago.  I believe he was the first DC that instituted traction or distraction to correct bulged or herniated discs. Moreover, he invented a chiropractic table and taught seminars on how to correct these problems. His work is great evidence that validates that the majority of spinal pain is caused by disc pressure on spinal nerve roots.  
 
8. Long Term Cryotherapy (LTCT) is very effective in reducing disc pain because it tends to contract the disc, and the tissues surrounding the swollen disc, relieving pressure on the SNR. If the source of the spinal pain was subluxation alone, cryotherapy could not contract the hard substance of the offending bone to produce the relief that LTCT consistently does. 
 
9. There are medical pain clinics springing up in various areas of the nation who advertise aggressively their minimal surgical technique to shrink the NP by laser surgery. They claim nearly 95% results. If the disc was not the offending cause, would they even get close to that % if only the subluxation existed?  They are so confident of their results that some of them don’t even accept insurance.  Cash only.  Cost to the patient?  10 to 20 thousand. 
 
10. Could this be why the chiropractic general adjustment works so well? When adjusting bilaterally down the entire length of the spine we often hear many audible releases. Could those releases be small protrusions being replaced (anteriorly) toward their normal positions? 
 
However, chiropractors need not worry, because our treatment is less costly and will one day become the treatment of choice.

For we can correct a large percent of subluxations/herniations a lot more reasonably and with far better outcomes than any other  method.  That doesn’t mean we can correct all disc protrusions, but most of them, in almost all areas of the spine. Therefore, it would be reasonable for people to try chiropractic first, medicine second, and surgery last, in that order to rid themselves of musculo-skeletal pain.
 
We all can do the job, but chiropractic can and should be tried first for 3 major reasons:
 
1. We can reduce multiple protrusions during each patient’s treatment, saving the patient untold amounts of future health care costs.  No other health profession can do this.
 
2. Even though repeated treatments may be needed, because discs can re-bulge with time, chiropractic is the lowest cost of all disc reduction methods. 
 
3. Since we can reduce the majority of disc herniations, then the few that won’t respond to chiropractic can be referred to other more costly and risky methods (decompression, laser, drugs, orthoscopic surgery, bone fusion, or the newest attempts of disc replacement). However, the most reasonable route to improvement is firstly the low-cost chiropractic way. 
 
In Conclusion:
 
Therefore, when disc involvement is detected by physical exams, MRIs, CT scans, etc., our diagnosis must include disc bulge, protrusion, or herniation along with subluxation. Whenever the profession adopts this finding, progress can be made with insurance acceptance, and with other healing professions. When the occasional patient isn’t responding well, the DC, having diagnosed the patient with subluxation/herniation, can refer them to the next level of appropriate treatment. He/she will have been credited with a correct diagnosis and will look good in the eyes of his/her patients, medical doctors, and surgeons. Subsequently, the chiropractic profession will gain in stature.
 
When this truth is fully accepted by chiropractic, the public, and other healing professions, then and only then will people use “Chiropractic first, medicine second, and surgery last.” Whoever created that phraseology was “right on target”.
 
Can you envision it?  If everyone used Chiropractic FIRST, there literally wouldn’t be enough DCs to take care of the people. This may be a long way off, but it could happen in our future. 
 
The TRUTH of a correct hypothesis shall set us free.
