Bouchard's nodes
Classification and external resources
ICD-10	M15.2

Bouchard's nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes.) They are a sign of osteoarthritis, and are caused by formation of calcific spurs of the articular (joint) cartilage.

Bouchard's nodes are comparable in presentation to Heberden's nodes, similar osteoarthritic growths on the distal interphalangeal joints, but are significantly less common.

[edit] Eponym

Bouchard's nodes are named after French pathologist Charles-Joseph Bouchard (1837-1915).^[1] [1]
