Rheumatoid arthritis - Joint inflammation
Rheumatoid arthritis is among the most debilitating of them all, causing joints to ache and throb and eventually become deformed. Sometimes these symptoms make even the simplest activities - such as opening a jar or taking a walk - difficult to manage.
Unlike osteoarthritis, which results from wear and tear on your joints, rheumatoid arthritis is an inflammatory condition. The exact cause is unknown, but it's believed to be the body's immune system attacking the synovium - the tissue that lines your joints.
It's two to three times more common in women than in men and generally strikes between the ages of 20 and 50. But rheumatoid arthritis can also affect young children and adults older than age 50.
There's no cure for rheumatoid arthritis. But with proper treatment, a strategy for joint protection and changes in lifestyle, you can live a long, productive life with this condition.
Arthritis involves inflammation of one or more joints and the breakdown of cartilage. Cartilage normally protects the joint, allowing for smooth movement. Cartilage also absorbs shock when pressure is placed on the joint, like when you walk or otherwise bear weight. Without the usual amount of cartilage, the bones rub together, causing pain, swelling, and stiffness.
Causes, incidence, and risk factors
You may have joint inflammation for a variety of reasons, including:
Often, the inflammation goes away after the injury has healed, the disease is treated, or the infection has been cleared.
With some injuries and diseases, the inflammation does not go away or destruction results in long-term pain and deformity. When this happens, you have chronic arthritis. Osteoarthritis is the most common type and is more likely to occur as you age. You may feel it in any of your joints, but most commonly in your hips, knees or fingers. Risk factors for osteoarthritis include:
Arthritis can occur in men and women of all ages. About 37 million people in America have arthritis of some kind, which is almost 1 out of every 7 people.
Other types or cause of arthritis include:
If you have arthritis, you may experience:
Signs and tests
First, your doctor will take a detailed medical history to see if arthritis or another musculoskeletal problem is the likely cause of your symptoms.
Next, a thorough physical examination may show that fluid is collecting around the joint. (This is called an "effusion.") The joint may be tender when it is gently pressed, and may be warm and red (especially in infectious arthritis and autoimmune arthritis). It may be painful or difficult to rotate the joints in some directions. This is known as "limited range-of-motion."
In some autoimmune forms of arthritis, the joints may become deformed if the disease is not treated. Such joint deformities are the hallmarks of severe, untreated rheumatoid arthritis.
Tests vary depending on the suspected cause. They often include blood tests and joint x-rays. To check for infection and other causes of arthritis (like gout caused by crystals), joint fluid is removed from the joint with a needle and examined under a microscope. See the specific types of arthritis for further information.
