Heberden nodes

The Heberden's nodes are deformations of the distal interphalangeal joints of the hand (DIP). Together with the Bouchard nodules, they are a clinical and graphical sign of osteoarthritis.

Etiology
Some work suggests that these are not purely osteoproductive changes, but that they are involved with both bone and ligament.

X-ray findings
In correlation with the clinic, we find nodes most often on the dorsolateral margin of the distal interphalangeal joints of the hand. This is a sign of advanced osteoarthritis.
