AIR: WHAT: Heberden's nodes. Heberden's Nodes: cartilaginous and bony enlargements of the distal interphalangeal joints of the fingers. WHY: The presence of Heberden's nodes is a common, characteristic physical finding of degenerative joint disease. HOW: Heberden's nodes are recognized by their characteristic location at the dorsolateral and medial aspects of the distal interphalangeal joints of the hand. They are usually nontender, painless, firm nodules 2 or 3 mm in diameter and are often associated with flexion and medial or lateral deviation of the distal phalanx.
