Ankylosing Spondylitis

Ankylosing spondylitis is a type of inflammatory arthritis that affects the spine and sacroiliac joints (hip). 

Ankylosing = fusing

Spondylitis = inflammation of the spine

This is caused by the body's immune system attacking the ligaments and tendons, causing erosion of the bones. To repair themselves, the body builds new bone resulting in the fusion of the bones. This causes the spine to become stiff, inflexible, and painful. Fusion of the spine can result in a hunched over posture. 

This condition affects: 

  • Men more often than women

  • 3.5 to 13 individuals per 1000


Symptoms of ankylosing spondylitis include:

  • Pain and stiffness in the lower back and hips

  • Pain and stiffness is worse in the morning and after periods of rest

  • Neck pain

  • Fatigue
