By definition, subluxation is a slight dislocation or biomechanical malfunctioning of the vertebrae. Stress, bad posture, sitting too long, slips/falls, automobile/work related accidents, sports injuries, just to name a few, all cause vertebrae to malfunction. This malfunction interferes with the nerves the spine is meant to protect and the interference causes irritation to the spinal cord, or nerve roots. The irritation of the nerves and the effects it produces is called a "Subluxation" or more precisely the Vertebral Subluxation Complex (VSC)
Vertebral - meaning relating to the bones of the spine or vertebrae;
Subluxation - meaning the improper motion or function of the vertebrae; and
Complex - meaning a condition consisting of many elements.
A Doctor of Chiropractic is the only doctor trained to detect, correct and help prevent the Vertebral Subluxation Complex using Chiropractic spinal manipulation (the adjustment) as the primary form of treatment. When the Vertebral Subluxation Complex is present a variety of effects on the spine, ligaments, tendons, muscles, organs and the tissues controlled by the affected nerves.
Spinal kinesiopathology - the abnormal movement of the structures of the spine causing restriction in movement.
Neuropathophysiology - the damage to the nerves - stretching, pinching or irritating - interfering with normal function resulting from abnormal movement.
Myopathology - the changes in muscle such as weakness, wasting, or spasm due to abnormal spinal movement.
Histopathology - the alterations in soft tissues, discs (bulging or herniation), and ligaments and the changes in the blood and lymph supply.
Pathophysiology - the cumulative, degenerative damage to the vertebrae (bone spurs) as it tries to stabilize and the effects of that on the organs and other tissues of the body.
