Psoriatic arthritis of psoriatic arthritis include the following: Other symptoms that are more typical of psoriatic arthritis than other forms of arthritis include enthesitis (inflammation in the Achilles tendon (at the back of the heel) or the plantar fascia (bottom of the feet)), and dactylitis (sausage-like swelling of the fingers or toes). Several conditions can mimic the clinical presentation of psoriatic arthritis including rheumatoid arthritis, osteoarthritis, reactive arthritis, gouty arthritis, systemic lupus erythematosus, and inflammatory bowel disease-associated arthritis. In contrast to psoriatic arthritis, rheumatoid arthritis tends to affect the proximal joints (e.g., the metacarpophalangeal joints), involves a greater number of joints than
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
