Subluxation is not a dislocation of a joint. “Sub” means less than and “luxation” means dislocation. A subluxation is less than a dislocation that can happen at any joint. When one has a subluxation it causes many dysfunctions. It can lead to dysfunction of the spinal nerves. Your nerves control all muscles, glands, organs and tissues. It can even lead to osteoarthritis if not treated properly. Chiropractors handle subluxation and prevent spinal decay, which in turn helps prevent disease.
