Editor's note: This is a compilation of three short articles from Dr. Joseph Kurnik, a practitioner from Torrance, California and frequent contributor to the California Forum.
• Undetected Thoracolumbar Problems • Lumbar Traction and Sacroiliac Joint Function • Right-Sided Lumbosacral Pain
Thoracolumbar problems here refers to lower thoracic and upper lumbar problems. More specifically, when examining this area in the seated position and placing the spine into extension, the upper lumbar or lower thoracic spine may appear to be normal or hypermobile. If you leave it this way and go to other areas, you may miss a great opportunity of discovering a hidden problem.
You should place the patient, which should include low back pain sufferers, in the prone position unless antalgic and unable to lie prone. You need to examine the lumbar and lower thoracic spine by testing in two main directions. These two directions are tested in the prone position:
I have found that this region can be most difficult to analyze and treat. Seated palpation may show an overall flexible lumbar spine, but when placed in the prone position; the spine is stabilized and individual extension restrictions can be detected. Previously, these extension restrictions were hidden by the overall flexibility of the lumbar and lower thoracic spine region.
I have also found that the correction of this region by adjustment is most easily achieved with an incline table. I use a table which is similar to the Pettibon style, but with some modifications which make adjusting easier for me (see DC, October 11, page C-4). Patients with very long and flexible arms, or very short and stocky arms, may not be suitable to this type of adjustment; Seated rotation and extension, or prone or supine adjusting, may be more effective.
Most of my patients, however, are easily treated in the incline position.
Of particular interest are the numbers of sacroiliac dysfunctions that clear or improve after treating the extension fixation at the thoracolumbar region. Motion palpating the SI joints before and after thoracolumbar adjusting will indicate the amount of SI functional restoration achieved.
Lumbar Traction and Sacroiliac Joint Function
The sacroiliac joints have an important function with regard to stabilization of the lumbar spine. Through the process of nutation or counter-nutation, the sacrum can be re-angulated. This re-angulation, even though minor, can affect the stress and stability of the lumbar spine, especially at the L-5/S-1 level.
During palpation examination and visual analysis, what one finds often is sacroiliac compensation for lumbar disorders in the form of AS (anterior superior) and PI (posterior inferior) hypomobile fixations (dysfunctions). Sacroiliac compensation also exists for thoracic kyphosis, dysfunction, and other problems. With relationship to the lumbar spine, L-4/5 and L-5/S-1 facet and lumbar disorders can exist, that cause frequent ilium AS fixation patterns, and less frequent PI ilium fixation patterns. As previously described in other DC articles, the lower lumbar segments exhibit rotation patterns which cause sacroiliac compensatory AS and PI ilium fixation patterns. In addition to lumbar rotation patterns, lumbar facet imbrication (facet compression) patterns can exist, especially in the L-4 and L-5 levels, which cause further sacroiliac compensations.
With regard to AS ilium fixation compensation reactions to lower lumbar facet compression, the most frequent and usual reaction is the bilateral AS ilium fixations, and less frequently the left or right AS fixation compensation. If lower lumbar rotation is not a concern, but lumbar posterior compartment compression is the concern (such as an L-5/S-1 facet syndrome with L-5/S-1 disc thinning); then segmental traction of L-5/S-1 can be done. Typically, a contact on the L-5 spinous process is made, and the L-5 segment is tractioned superior. If the AS fixations are monitored before and throughout prior to and after traction, you can frequently witness a partial or complete release of the AS ilium fixation patterns. This is a useful diagnostic tool. If no AS ilium fixation release is noticed; the procedure is not what is needed. If the AS fixation pattern is compensatory, then you will usually see a change in the SI patterning with the proper treatment. There may be other contributing factors, such as:
With regard to the tractioning of the lumbar segments with spinous contacts, frequently there will be too much tenderness at the site of the pain, and you are unable to traction comfortably the compressed lumbar or lumbosacral joint. A deviation from normal procedure may solve this problem. Instead of tractioning by contact on the spinous process, contact the mid-sacral region with one palm. With the other hand, depress the traction table so that the caudal end flexes anteriorly towards the floor while the contact hand tractions the sacrum inferiorly and anteriorly. Frequently, the lumbar tenderness will be absent or reduced, symptoms will improve, and sacroiliac fixation compensation will be reduced (i.e., the AS ilium pattern will be absent or decreased).
In summary, the analysis of sacroiliac functioning often supplies information about the effectiveness of your treatment.
Right-Sided Lumbosacral Pain
This is a unique, yet common disorder. Right-sided lumbosacral pain can be more difficult to control than left-sided pain. Excluding significant lumbar disc injury and transition elements, a few situations emerge most commonly:

Many relevant diagnostic signs are not performed deliberately by the examiner or by the patient at the examiner’s direction. They are observed as the patient reacts to their condition. Fortin’s finger sign, Minor’s sign, and Vanzetti’s sign are three examples of this principle.
Spearheaded by burgeoning scientific and clinical research literature, psychedelics have reached a level of media coverage and popular interest that has not been seen for over half a century. By “psychedelics,” we are referring to the unique class of substances that includes psilocybin (the active compound found in so-called “magic mushrooms”), LSD, dimethyltryptamine (DMT), ayahuasca, 5-MeO-DMT, and mescaline – each of which occurs in the natural world (except for LSD, which is a semi-synthetic compound).
While working at the Lovelace Medical Center in Albuquerque, N.M., one of the primary care physicians stated that imaging every patient prior to receiving chiropractic was not medically necessary. It was at that point I reconsidered the need for the imaging of every patient to avoid malpractice.
