Ankylosing spondylitis is a chronic inflammatory disease that mainly affects the joints of the spine, which tend to weld together, causing a limitation of mobility. As a final result there is a loss of flexibility of the column, remaining rigid and fused. It usually appears in men between 20 and 30 years of age and in women, is less frequent and is usually milder.
