Ankylosing Spondylosis

What is Anklyosing Spondylosis?

Ankylosing Spondylosis is a chronic inflammatory disease of the joints of the spine. manifested by fusion(ankylosing) and inflammation( spondylosis) of some or all of the joints and bones of the spine. It is a painful progressive disease affecting mainly the spine. It can also affect other joints, tendons,ligaments, also other areas such as eyes, lungs, bowels and heart.

Who get Ankylosing Spondylosis?

Every one can get Ankylosing Spondylosis. The age of onset is usually in the late teens or early 20’s. It is also more common in men than women about 5:1. In men the spine and pelvis are most affected. In women the pelvis,hips, knees,wrists and ankles are more common.

How does Ankylosing Spondylosis occur?

Inflammation occurs at the attachment of the ligaments and tendons to the bone. Erosion of the bones occur at the site. When the inflammation subside, new bone develop and replaces the elastictissues of the ligaments or tendons. Fusion of bones occur leading to restriction of movement. This usually starts in the vertebra of the spine followed by the pelvis, then upwards to the chest wall and neck.

What are the Symptoms?

The onset is usually gradual with occasional back pain over weeks or months. Early morning stiffness and pain occurs,then wears off during the day. It gradually becomes affecting the lower back first then upwards to to the neck, resulting in stiffening of the back. Chest expansion can become limited because of the the stiffness of the bones. Sometimes peripheral joints such as shoulders and hips are affected. Weight loss and fatigue may occur in the early stages. ESR is raised in most cases. RA factor is not present.

Inflammation of the iris of the eye(Uveitis) occur in 5% of cases with blurring of vision. Occasionally it may affect the heart causing the aortic valve to leak. The rib joints and muscles are also affected resulting tightness of the chest making breathing painful.

How is Ankylosing Spondylosis diagnosed?

Confirmation is usually by an xray of the spine and pelvis.
