Spondylitis is a kind of arthritis, which affects the spine in the body. The spine bones grow into a rigid structure by fusing with each other. This causes pain and stiffness in the upper and lower portions of the back. The cause of spondylitis is still unknown. It is believed that a gene called HLA-B27 is involved. Till now, no permanent cure for spondylitis has been found. However, early diagnosis and treatment procedures are essential to improve symptoms.
