They are a sign of [[osteoarthritis]], and are caused by formation of [[calcification|calcific]] [[bone spur|spurs]] of the articular (joint) [[cartilage]]. Bouchard's nodes are comparable in presentation to [[Heberden's node]]s, similar osteoarthritic growths on the [[distal interphalangeal joint]]s, but are significantly less common. ==Eponym== Bouchard's nodes are named after French [[pathologist]] [[Charles-Joseph Bouchard]] (1837-1915).<ref>{{WhoNamedIt|synd|1893}}</ref> [http://content.revolutionhealth.com/contentimages/media-medical-hw-nr551642.jpg] ==References== <references/> ==External links== *[http://www.webmd.com/hw/health_guide_atoz/zm2488.asp Diagram of Heberden's and Bouchard's nodes] at [[WebMD]] {{Diseases of the musculoskeletal system and connective tissue}} [[Category:Medical signs]] {{medicine-stub}}
