Psoriatic arthritis psoriatic arthritis, and affect them symmetrically. Involvement of the spinal joints is more suggestive of psoriatic arthritis than rheumatoid arthritis. Osteoarthritis shares certain clinical features with psoriatic arthritis such as its tendency to affect multiple distal joints in an asymmetric pattern. Unlike psoriatic arthritis, osteoarthritis does not typically involve inflammation of the sacroiliac joint. Psoriatic arthritis sometimes affects only one joint and is sometimes confused for gout or pseudogout when this happens. There are five main types of psoriatic arthritis: The underlying process in psoriatic arthritis is inflammation; therefore, treatments are directed at reducing and controlling inflammation.

Sacroiliac joint dysfunction studies have found up to 75% of post-lumbar fusion patients develop SI joint degeneration within five years of surgery. Pathological hypomobility (too little movement) of the sacroiliac joint is an intra-articular disorder in which the joint locks due to wearing down with age or degenerative joint disease. Hypomobility of this kind can also occur with an inflammatory disease such as ankylosing spondylitis, rheumatoid arthritis, or an infection. The sacroiliac joint is a true diarthrodial joint that joins the sacrum to the pelvis. The sacrum connects on the right and left sides to the ilia (pelvic bones) to form the sacroiliac
