Heberden's nodes are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes). [1] They are a sign of osteoarthritis and are caused by formation of osteophytes (calcific spurs) of the articular (joint) cartilage in response to repeated trauma at the joint.
As pain may make it difficult to exercise, muscle loss may occur. [2] [10] Diagnosis is typically based on signs and symptoms, with medical imaging and other tests used to support or rule out other problems.
