One of the most common forms of inflammatory arthritis is gout. 1, 2 If you have trigger finger and have other risk factors or signs of psoriatic arthritis, talk to your doctor about getting screened for the disease. Research suggests that trigger finger may be a risk factor for psoriatic arthritis. If psoriatic arthritis causes a finger or thumb’s tendon enthesis to become inflamed, the connected tendon sheath may also become inflamed, causing trigger finger. These attachment points are called entheses. The inflammation caused by psoriatic arthritis primarily occurs where tendons and ligaments attach to bone tissue. Like people who have RA, people who have psoriatic arthritis have painful joint inflammation. See Hand Rheumatoid Arthritis Signs and Symptoms It is not surprising that RA inflammation that affects the finger joints’ synovial membrane is associated with trigger finger. Joint lining is a type of synovial membrane-the same kind of membrane that becomes inflamed in cases of trigger finger. The inflammation occurs when the immune system attacks the delicate lining that surrounds a joint. People who have rheumatoid arthritis have painful joint inflammation. Rheumatoid arthritis, psoriatic arthritis, and gout are three types of arthritis linked to trigger finger.

The tissues of the hand and fingers are interconnected, and inflammation in one area of tissue can have cascading effects, including trigger finger. Arthritic conditions associated with trigger fingerĪrthritis of any kind can cause inflammation in the joints, and that inflammation is not necessarily isolated and contained.
