Types of psoriatic arthritis

There are five different types of psoriatic arthritis, determined by which parts of the body are affected as well as the extent and severity of inflammation:

Hands with symmetric arthritis

Symmetric arthritis

Symmetric arthritis usually affects the same joints on both sides of the body. Usually multiple pairs of joints, such as the right and left knees or right and left elbows, are affected. This type of psoriatic arthritis resembles rheumatoid arthritis, but it’s generally milder.

Hand with asymmetric arthritis

Asymmetric arthritis

Asymmetric arthritis doesn’t typically affect the same joints on both sides of the body. Usually, it affects the fingers and toes first, which can lead to an enlarged and “sausage-like” appearance. Sometimes a larger joint, like the knee, is also affected.

Fingernails with distal interphalangeal predominant

Distal interphalangeal (DIP) predominant

DIP affects the joints in the fingers and toes closest to the nail; nail changes are common.

Person with spondylitis grabbing back

Spondylitis

Spondylitis refers to inflammation of the spinal column. Many people with psoriatic arthritis will have stiffness in the neck, lower back, or spinal vertebrae, making motion painful and difficult.

Hand with arthritis mutilans

Arthritis mutilans

Arthritis mutilans is a severe, deforming, and destructive form of psoriatic arthritis. It usually affects the small joints at the ends of the hands and feet.
