title: Diagnosing joint pain in the older people.
abstract: There are many potential causes of joint pain in older patients. The most likely aetiology is OA. However, the differential diagnosis includes conditions which should not be missed such as septic arthritis and inflammatory disease. The pattern of joint involvement points to the diagnosis. Bilateral symmetrical small joint pain, swelling and stiffness should arouse the suspicion of RA. The wrist and knee are commonly affected by pseudogout and the first metatarsophalangeal joint or knee joint involvement may represent gout. Stiffness in the shoulder and hip girdles, worse in the morning, suggests polymyalgia rheumatica. In straightforward cases of OA no specific investigations are required. If doubt exists, however, tests may be necessary including FBC, ESR and CRP, uric acid for suspected gout and X-rays of the affected joints especially following trauma, or pseudogout. Patients with OA should be offered education and advice as well as strengthening exercises and aerobic fitness training (if physically possible). If the patient is overweight, weight loss is critical, especially in OA of the knee. Paracetamol and topical NSAIDs are the first-line drug treatments. Elderly onset RA differs from younger onset RA in the following ways: a more balanced gender distribution; a higher frequency of acute onset; an association with systemic features; more frequent involvement of the shoulder girdle and higher disease activity. DMARD therapy should be used according to disease severity, as in younger onset RA. The current approach is for early, intensive intervention with combination therapy. Corticosteroids may be very effective in the elderly, however, prolonged use and/or high dosage may lead to marked toxicity especially osteoporosis and diabetes.
