Explanation:

Rheumatoid arthritis (RA) is an autoimmune inflammatory arthritis. It typically affects the proximal interphalangeal joints, metacarpophalangeal joints, wrists, elbows, shoulders, knees, ankles, and toes. The distal interphalangeal joints are usually spared in RA. Psoriatic arthritis often involves the distal interphalangeal joints. Erosive osteoarthritis mainly affects the distal interphalangeal joints. Reiter's syndrome (now known as reactive arthritis) can involve various joints including those in the hands and feet.
