The Hangover: The Early and Lasting Effects of the Controversial Incorporation of X-Ray Technology into Chiropractic.

Chiropractic first adopted the X-ray in 1910 for the purpose of demonstrating tiny misalignments of spinal bones, theorised to cause all disease, which they called chiropractic subluxations. This paper explores the apparent contradiction and resultant controversy of a system of natural healing adopting a medical technology. It centres on the actions of B.J. Palmer, the first chiropractor to use X-rays. It also clarifies details of Palmer's decision to incorporate the technology and interprets the change in the sociological context of boundary work. The continuing use of the subluxation paradigm for radiography by chiropractors has had a lingering effect on the profession, a metaphorical hangover of vitalism that is not consistent with modern healthcare practice. As a result of this conflict, arguments within the profession on the use of X-rays contribute to the continuing schism between evidence-based and subluxation-based chiropractors.
