Ankylosing means stiffening and fusing while Spondylitis means inflammation of the spine. Ankylosing Spondylitis describes the condition where some of the joints and bones of the spine become fused together because of inflammation.

Enteropathic Arthritis
Affecting the Spine & Peripheral Joints

Juvenile Spondyloarthritis describes a group of arthritic diseases that start before the 16th birthday. The term Juvenile Idiopathic Arthritis (JIA) was introduced to standardize and classify the different arthritic conditions seen in children.

Psoriatic Arthritis
Psoriasis and Arthritis Meet

Psoriasis is an inflammatory disease of the skin and nails. About 30% of people with psoriasis also develop Psoriatic Arthritis and of these about 20% go on to experience some spinal involvement.

Reactive Arthritis
A Reaction To An Infection

Reactive Arthritis can cause inflammation and pain in joints, the skin, eyes, genitals and bladder, as well as persistent lower back pain.

Undifferentiated Spondyloarthritis
May Progress to AS or Develop Psoriasis or IBD

The new classification system of axial and peripheral SpA may encompass most patients with SpA, hence there are very few patients who are classified as USpA currently.
