Arthritis (from Greek arthro-, joint + -itis, inflammation; plural: arthritides) is a group of conditions where there is damage caused to the joints of the body. Arthritis is the leading cause of disability over the age of 65. There are many forms of arthritis, each of which has a different cause. Rheumatoid arthritis and psoriatic arthritis are autoimmune diseases in which the body is attacking itself. Septic arthritis is caused by joint infection. Gouty arthritis is caused by deposition of uric acid crystals in the joint and subsequent inflammation. The most common form of arthritis, osteoarthritis is also known as degenerative joint disease and occurs following trauma to the joint, following an infection of the joint or simply as a result of aging. There is emerging evidence that abnormal anatomy may contribute to early development of osteoarthritis.
History and physical examination All arthritides feature pain. Patterns of pain differ among the arthridities and the location. Osteoarthritis is classically worse at night or following rest. Rheumatoid arthritis is generally worse in the morning and in the early stages, patients often do not have symptoms following their morning shower. In elderly people and children, pain may not be the main feature, and the patient simply moves less (elderly) or refuses to use the affected limb (children). Elements of the history of the pain (onset, number of joints and which involved, duration, aggravating and relieving factors) all guide diagnosis. Physical examination typically confirms diagnosis. Radiographs are often used to follow progression or assess severity in a more quantitiative manner. Blood tests and X-rays of the affected joints often are performed to make the diagnosis. Screening blood tests may be indicated if certain arthridities are suspected. This may include: rheumatoid factor, antinuclear factor (ANF), extractable nuclear antigen and specific antibodies. Types of arthritis Primary forms of arthritis: Secondary to other diseases: Treatment Treatment options vary depending on the type of arthritis and include physical and occupational therapy, medications (symptomatic or targeted at the disease process causing the arthritis), and as a last resort, arthroplasty. Although prosthetic joint replacement is a treatment of last resort, it is generally very effective and more than 90% of patients are very satisfied. | ||||||||
