title: Hydroxyapatite deposition disease.
abstract: Hydroxyapatite crystals are a common cause of periarticular disease, but recent studies have shown that they may also be deposited intra-articularly, either as a primary phenomenon or secondary to another disease. A continuum of abnormalities from monoarticular periarthritis to polyarticular disease and finally joint destruction may occur.
