Featured: Hydroxyapatite Crystal Disease Main Article

Hydroxyapatite crystal disease is the inflammation caused by hydroxyapatite crystals. These tiny crystals of hydroxyapatite deposit by mistake in or around joints and may cause inflammation of the joints and nearby tissues such as the tendons and ligaments (particularly causing rotator cuff problems in the shoulder). Treatment options include rest, cold application, medications to reduce inflammation, and cortisone-related medication injections.
