In osteoarthritis, where are Heberden's nodes typically found?

Heberden's nodes are bony enlargements that occur at the distal interphalangeal (DIP) joints of the fingers. They are a characteristic feature of osteoarthritis, particularly affecting the hands. These nodes result from the formation of osteophytes (bone spurs) and other changes associated with degenerative joint disease.

In osteoarthritis, the DIP joints are particularly prone to these changes due to the high levels of stress and mechanical load they experience over time. The presence of Heberden's nodes often indicates that the osteoarthritis is localized to the hand and can help differentiate it from other forms of arthritis, particularly rheumatoid arthritis, which tends to affect the proximal interphalangeal (PIP) joints more frequently.

Understanding the locations of these nodes assists healthcare professionals in diagnosing and managing osteoarthritis effectively.
