Arthritis - Osteoarthritis
Arthritis—literally, “inflamed joint”—can affect any joint in the body, including the joints between the 29 bones of the wrist, hand, and fingers. Arthritis of the hand can hurt and keep you from being able to do what you want or need to do. The most common forms of arthritis in the hand are osteoarthritis, post-traumatic arthritis (after an injury), and rheumatoid arthritis. Osteoarthritis is a degenerative joint disease in which the smooth cartilage that covers the bone surfaces at the joints either is injured or wears over time.
