![]() ![]() The first knuckle at the top of the finger closest to the nails - the DIP, or distal interphalangeal joint - is generally spared in RA. When RA strikes the hand, it is most common in the wrist and finger knuckles - more specifically the MCP (metacarpophalangeal) joint, or the large knuckle where the fingers and thumb meet the hand, and the PIP (proximal interphalangeal) joint, or middle knuckle, explains Jemima Albayda, MD, Assistant Professor of Medicine in the Division of Rheumatology at Johns Hopkins Medicine in Baltimore. Ligaments are connective tissues that join two bones tendons are connective issues that join muscle to bone. The inflammation may also weaken and damage tendons. The swollen tissue may stretch the surrounding ligaments, resulting in deformity and instability, according to the American Society for Surgery of the Hand. That extra fluid - along with the inflammatory chemicals released by the immune system - causes swelling, damages cartilage, and softens the bone within the joint. When you have rheumatoid arthritis, the synovium becomes inflamed, thickens, and produces an excess of joint fluid. Many joints are covered with a lining called the synovium, which lubricates the joint so it moves more easily. How Rheumatoid Arthritis Affects Your Hands Read more here about common rheumatoid arthritis symptoms. Research suggests an estimated 90 percent of people will RA experience pain, stiffness, or swelling in joints in their hand, and often results in problems performing daily activities. ![]() Though RA can affect joints and organs all over the body, it often strikes in smaller joints first - particularly those in your hand and wrist, as well as ones in your feet. Rheumatoid arthritis is a chronic, inflammatory disease in which your immune system mistakenly attacks the lining of the membrane that surrounds your joints. All of this complexity also makes the hand a prime target for rheumatoid arthritis (RA). Made up of the wrist, palm, and fingers, each hand contains 27 small joints, the same number of bones, and a whole lot of muscles, tendons, and ligaments. It’s designed to give powerful grip, lift heavy objects, and manipulate small ones (like threading a fine string through a tiny needle eye). At the end of the procedure the screw position is checked using a special X-ray machine in the operating theatre.Your hand is one of the most complex structures in the human body. At the end of the procedure the screw position is checked using a special X-ray machine in the operating theatre.Īn open reduction using 1 or 2 screws is usually the preferred option in treatment.
