'Spondylo' means affecting the spine and 'arthritis' means joint disease. Spondyloarthritis (also known as spondyloarthropathy or seronegative arthritis)  is a name for types of arthritis that commonly affect the spine. These types of arthritis all have the following signs in common:

  • inflammation of
  1. the spine and sacroiliac joints (joints that connect the base of your spine to your pelvis), felt as poin and stiffness in the buttocks, back and/or neck
  2. joints in the legs and less commonly the arms, causing pain, stiffness and swelling
  3. tendons (strong cords that connect muscles to bones) and ligaments ( which connect bones to each other), often felt as pain in the back of the heel or underneath the foot
  4. eyes, skin and other parts of the body
  • seronegative (meaning 'absent from the blood'). Types of arthritis that test negative for rheumatoid factor in the blood are called seronegative arthritis. 
  • associated with a gene called HLA-B27

Another name used for this group of conditions is spondylitis, meaning inflammation of the spine. There are several types of arthritis that can be classified as spondyloarthritis
