Crystal Arthropathy in the Elderly Population

Gout, pseudogout and hydroxyapatite related articular and periarticular syndromes are among the most commonly seen rheumatic conditions in the elderly. A recently renewed interest in these diseases resulted in progress both in the field of imaging and treatment of crystal arthropathies, especially in gout. Calcium pyrophosphate dihydrate deposition disease, sometimes also named pseudogout, shares many common features with gout, and extrapolations have been made between the two diseases in terms of diagnosis means and new treatment. Hydroxyapatite deposition disease is responsible mainly for shoulder periarticular syndrome and may contribute to the progression of osteoarthritis, but lack of specific and widely available diagnostic tools and efficient treatment makes its diagnosis and management difficult.
