The argument about safety concerns is an example of “junk science” and a perennial favorite by those who have an interest in discouraging people from seeking chiropractic care.
Because of the popularity of this tactic, year after year it has been the subject of countless research projects. The result of these studies show complications from neck adjustments, the supposedly “riskiest” chiropractic procedure, are exceedingly rare:
1972 – One death in several tens of million adjustments.
1978 – One in 10,000,000 neck adjustments.
1981 – One in a 1,000,000 neck adjustments.
1983 – Two to three per 1,000,000 adjustments.
1985 – One in 400,000 neck adjustments.
1993 – One in 3,846,153 neck adjustments.
1995 – One in 2,000,000 neck adjustments.
1996 – One in 900,000 neck adjustments.
The most recent in-depth review of the relationship between stroke and chiropractic care, was published in the February 15, 2008 issue of Spine Journal. It looked at 10 years of hospital records, involving 100 million person-years.
There was no evidence of an increase in vertebral artery dissection risk with chiropractic, compared with medical management. Based on this review, stroke, particularly vertebrobasilar dissection, should be considered a random and unpredictable complication of any neck movement, including cervical manipulation.
In other words, cases of serious injury are practically nonexistent. By comparison, it makes the deaths caused by over-the-counter-pain-relievers to be considerably more troubling! Although reports vary, annual deaths in the United States attributable to NSAIDs (Non-Steroidal Anti-Inflammatory Drugs such as aspirin, ibuprofen, naproxen, diclofenac, ketoprofen and tiaprofenic acid) range from 3,200 to higher than 16,500 deaths and 76,000 hospitalizations.
Even risk-adverse insurance companies recognize the safety of today’s chiropractic care. The premiums for malpractice insurance paid by chiropractors are a mere fraction of what medical practitioners must pay. Chiropractic care is safe.
