Ankylosing Spondylitis is a type of arthritis which causes recurring inflammation of the spinal bones and other joints such as sacroiliac joints. It is a chronic disorder which is also known as Marie-Strümpell disease or Bechterew’s syndrome. The symptoms of this condition include pain and stiffness from the neck down to the lower back.
There is no known reason as to what causes Ankylosing Spondylitis, but there is a lot of information available about what effects it has on the body, and why it causes the vertebrae to become stiff and rigid.
People who have the particular HLA-B27 gene have a significantly greater risk of developing AS, but there are many people who have this gene that never develops AS. Infectious agents may be involved in the development of the disease.
