Arthritis of the spine is something that we deal with on a daily basis. There are several types of arthritis however; osteoarthritis, also known as degenerative joint disease, is the most common arthritis of all. Most everyone over the age of 40 has it to some degree. In some people it may cause little or no symptoms, whereas in others the symptoms may be severe. OA is usually the result of too much wear and tear or stress on the joints. In the case of the spine, its presence may be a sign that it is out of alignment or balance. It may also be the result of trauma to the spine, especially in the case of past car accidents or other significant trauma in years past.
