What is a Subluxation? A subluxation is a medical term describing a partial or incomplete dis-location of a joint. A spinal subluxation describes a condition where a vertebra “spinal bone” has lost it’s normal position in relation to the vertebra above or below. The subluxation can then cause irritation to the joint or nerve, “Facet Syndrome” or a “Pinched Nerve”, and possible associated pain. Doctors of Chiropractic such as Dr. Glen Batson of Willowbrook Il, are trained in the detection of, and restoration of, the spinal misalignment, “Subluxation”.
