Heberden's nodes are hard or bony swellings that can develop in thedistal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes).[1] They are a sign ofosteoarthritis and are caused by formation ofosteophytes (calcificspurs) of the articular (joint)cartilage in response to repeated trauma at the joint.[2]
Heberden's nodes typically develop in middle age, beginning either with achronic swelling of the affected joints or the sudden painful onset of redness, numbness, and loss of manualdexterity. This initial inflammation and pain eventually subsides, and the patient is left with a permanent bony outgrowth that often skews the fingertip sideways.Bouchard's nodes may also be present; these are similar bony growths in the proximal interphalangeal (PIP) joints (middle joints of the fingers), and are also associated with osteoarthritis.
Heberden's nodes are more common in women than in men, and there seems to be agenetic component involved in pre-disposition to the condition.
They are named afterWilliam Heberden (1710–1801).[3]
