Subluxation

A subluxation may have different meanings, depending on the medical specialty involved. It implies the presence of an incomplete or partial dislocation (Latin: luxatio) of a joint or organ. The World Health Organization (WHO) defines both the medical subluxation and the chiropractic subluxation. It contrasts the two and states in a footnote that a medical subluxation is a "significant structural displacement, and therefore visible on static imaging studies."
