What does ankylosing spondylitis mean?
Ankylosing means fusing together. Spondylitis indicates inflammation of the vertebrae. Both words come from the Greek. So, AS describes the condition by which some or all of the joints and bones of the spine fuse together. Entire fusing of the spine is unusual. Many people will only have partial fusion, sometimes limited to the pelvic bones. - return to top
What exactly is AS?
AS is a painful, progressive, rheumatic disease. It mainly affects the spine but it can also affect other joints, tendons and ligaments. Other areas, such as the eyes, lungs, bowel and heart can also be involved. - return to top
What actually happens?
Inflammation occurs at the site where certain ligaments or tendons attach to bone (enthesis). This is followed by some erosion of bone at the site of the attachment (enthesopathy). As the inflammation subsides, a healing process takes place and new bone develops. Movement becomes restricted where bone replaces the elastic tissue of ligaments or tendons. Repetition of this inflammatory process leads to further bone formation and the individual bones which make up your backbone, the vertebrae, can fuse together. The pelvis is commonly affected first. The lower back, chest wall and neck may also become involved at different times. - return to top
Is ankylosing spondylitis the same as spondylosis?
No. They sound similar but they are different. Spondylosis is a term relating to "wear and tear" and is more common in older people. AS relates to an inflammatory condition which produces new bone and leads to fusion. The vigorous exercise therapy designed for people with AS might be harmful to those suffering from spondylosis. - return to top
Is AS common?
AS affects approximately 1 in 200 men and 1 in 500 women in Britain. - return to top
Who gets AS?
Men, women and children can all suffer from AS. It typically strikes people in their late teens and twenties, with the average age being 24. However, symptoms can start at other periods of life. AS is more common in men, with nearly three times as many men having it as women. - return to top
Is AS different in men, women and children?
Yes. AS tends to affect men, women and children in slightly different ways. Men: The pelvis and spine are most commonly affected. Other joints which may be involved are the chest wall, hips, shoulders and feet. - return to top
Women: Involvement of the spine is generally less severe than in men. The pelvis, hips, knees, wrists and ankles are the most commonly involved. Children: It is unusual for a child under the age of 11 to develop symptoms of AS. The joints which are typically affected first are the knees, ankles, feet, hips and buttocks. They rarely suffer from back pain. In youngsters, AS may lead to persistent hip disease ultimately requiring a hip replacement sometime in adult life. - return to top
What are the symptoms of AS?
Typical symptoms of AS include:
Slow or gradual onset of back pain and stiffness over weeks or months, rather than hours or days.
Early-morning stiffness and pain, wearing off or reducing during the day with exercise.
Persistence for more than three months (as opposed to coming on in short attacks).
Feeling better after exercise and feeling worse after rest.
Weight loss, especially in the early stages.
Fatigue.
Feeling feverish and experiencing night sweats. - return to top
Does AS affect other joints?
Yes. AS sometimes causes aching, pain and swelling in the hips, knees and ankles. Indeed, any joint can be affected. In most cases the pain and swelling will settle down after treatment. It is particularly important to stretch the hip joint to prevent stiffening in a bent position making you lean forward. The heel bone can become particularly troublesome causing pain in two areas. Most common is the under surface, about three centimetres from the back of the foot. This is called plantar fasciitis and
