Diagnosis of Arthritis
Arthritis is characterized by inflammation of the joints, and is often accompanied by pain, swelling and stiffness. One or more joints may be affected by the arthritis. Rheumatoid arthritis occurs when the joints are attacked by their own immune system. Osteoarthritis occurs when cartilage wears away, leaving no protective barrier between connecting bones. Arthritis may be diagnosed using the following methods.
X-Rays
X-rays can be used to determine if cartilage loss has occurred. Also, X-rays will show if the bones have been damaged or if any bone spurs are present.
MRIs
An MRI allows a physician to see if any problems exist with ligaments, tendons, bones or cartilage.
Arthroscopy
An arthroscopy is performed by threading a tiny tube into the joint through a small incision in the body. The arthroscope then takes pictures of the inside of the joint. These pictures can be analyzed to see if joint damage is present.
Lab Tests
Physicians can use joint fluid, urine or blood samples to look for indicators of arthritis present in those body substances. One indicator of arthritis is the presence of the antinuclear antibody.
Treatment
Medications can be used to reduce inflammation and pain. Also, physical therapy may be beneficial. For severe arthritis, surgery may be needed.
