This recent article is truly remarkable:

There is a faction within the chiropractic profession passionately advocating against the routine use of X-rays in the diagnosis, treatment and management of patients with spinal disorders (aka subluxation). These activists reiterate common false statements such as “there is no evidence” for biomechanical spine assessment by X-ray, “there are no guidelines” supporting routine imaging, and also promulgate the reiterating narrative that “X-rays are dangerous.” These arguments come in the form of recycled allopathic “red flag only” medical guidelines for spine care, opinion pieces and consensus statements. Herein, we review these common arguments and present compelling data refuting such claims. It quickly becomes evident that these statements are false. They are based on cherry-picked medical references and, most importantly, expansive evidence against this narrative continues to be ignored. Factually, there is considerable evidential support for routine use of radiological imaging in chiropractic and manual therapies for 3 main purposes: 1. To assess spinopelvic biomechanical parameters; 2. To screen for relative and absolute contraindications; 3. To reassess a patient’s progress from some forms of spine altering treatments. Finally, and most importantly, we summarize why the long-held notion of carcinogenicity from X-rays is not a valid argument.

Not only is low dose radiation not detrimental, but it also protects us from cancer, according to the authors:

Exposures to low-dose radiation incites multiple and multi-hierarchical biopositive mechanisms that prevent, repair or remove damage caused mostly by endogenous reactive oxygen species (ROS) and H2O2 from aerobic metabolism. Indeed, non-radiogenic (i.e. naturally occurring) molecular damage occurs daily at rates many orders of magnitude greater than the rate of damage caused by low-dose radiation such as diagnostic X-rays. It is estimated that the endogenous genetic damage caused on a daily basis from simply breathing air is about one million times the damage initially resulting from an X-ray. We concur that “it is factually preposterous to have radiophobic cancer concerns from medical X-rays after considering the daily burden of endogenous DNA damage.”

And, of course, radiological imaging makes sense in cases of non-specific back pain due to ‘malalignment’ of the spine:

Pressures to restrict the use of “repeat” (i.e. follow-up) X-rays for assessing patient response to treatment shows a complete disregard for the evidence discussed that definitively illustrates how modern spine rehabilitation techniques and practices successfully re-align the spine and pelvis for a wide variety of presenting subluxation/deformity patterns. The continued anti-X-ray sentiment from “consensus” and opinion within chiropractic needs to stop; it is antithetical to scientific reality and to the practice of contemporary chiropractic practice. We reiterate a quote from the late Michael A. Persinger: “what is happening in recent years is that facts are being defined by consensus. If a group of people think that something is correct, therefore it’s true, and that’s contradictory to science.”

Thus, the authors feel entitled to conclude:

Routine and repeat X-rays in the nonsurgical treatment of patients with spine disorders is an evidence-based clinical practice that is warranted by those that practice spine-altering methods. The evidence supporting such practices is based on definitive evidence supporting the rationale to assess a patient’s spinopelvic parameters for biomechanical diagnosis, to screen for relative and absolute contraindications for specific spine care methods, and to re-assess the spine and postural response to treatment.

The traditional and underlying presumption of the carcinogenicity from X-rays is not a valid notion because the LNT is not valid for low-dose exposures. The ALARA radiation protection principle is obsolete, the threshold for harm is high, low-dose exposures prevent cancers by stimulating and upregulating the body’s innate adaptive protection mechanisms, the TCD concept in invalid, and aged cohort studies assumed to show cancers resulting from previous X-rays are not generalizable to the wider population because they represent populations predisposed to cancers.

Red flags, or suspected serious underlying disease is a valid consideration warranting screening imaging by all spine care providers. We contend, however, that as long as the treating physician or rehabilitation therapist is practicing evidence-based methods, proven to improve spine and postural parameters in order to provide relief for the myriad of spinal disorders, spinal X-rays are unequivocally justified. Non-surgical spine care guidelines need to account for proven and evolving non-surgical methods that are radiographically guided, patient-centered, and competently practiced by those specialty trained in such methods. This is over and above so-called “red flag only” guidelines. The efforts to universally dissuade chiropractors from routine and repeat X-ray imaging is neither scientifically justified nor ethical.

There seems to be just one problem here: the broad consensus is against almost anything these authors claim.
