Psoriatic spondylitis, also called psoriatic arthritis (PsA), is a type of spondyloarthritis. This group of autoimmune diseases causes inflammatory arthritis and other symptoms throughout the body. Here, we will discuss the symptoms and causes of psoriatic spondylitis, as well as how it is diagnosed and treated.
Different types of spondylitis can affect different parts of the body. Psoriatic spondylitis can affect any joint, causing inflammation, pain, and progressive tissue damage.

Psoriatic spondylitis may also develop after certain infections, including Streptococcal pharyngitis (strep throat), trigger the immune system to mount a faulty immune response.
