A<unk>  is an incomplete or partial dislocation of a joint or organ. According to the World Health Organization (WHO), a<unk>  is a "significant structural displacement", and is therefore always visible on static imaging studies, such as X-rays. In contrast, the chiropractic belief of "vertebral<unk> " may or may not involve a significant displacement or even pain or clear dysfunction.
