Subluxation Degeneration is caused by subluxations that have been continuing on for between 40 and 65 years. This phase has all of the attributes of the previous phases, only worse. The curvatures are abnormal, the disc spaces are vastly decreased and changed. Calcium changes on the spine are abundant in this phase. Normally, people in phase three have a restricted range of motion and probably exhibit symptoms of some kind. In phase three the vertebrae show obvious changes and mutations in shape. Projections made of calcium, sometimes referred to as “spurs or lipping”, can be readily seen on x-ray. Chiropractic reconstructive care for patients in phase three ranges from 2.5 years to 3.5 years. This does not mean that at the end of this time that any or all of the calcium changes will be gone. In many instances the body adapts to the presence of the calcium and positive changes can only be measured from a functional standpoint. As before, if Phase Three Subluxation Degeneration is left unchecked it slowly advances onward into the next phase.
