What is the difference between Herbenden’s and Buchard’s Nodes? What do they look like?
Heberden’s nodes (at the DIP joints– most distal knuckle) and Bouchard’s nodes (at the PIP — middle knuckle) of the hands look like bony enlargement (knobs or nodes) at the joint. They are hard (becasue they are bone) and occasionally become inflammed and painful. Both are features of osteoarthritis.
