Where are Heberden's nodes typically found?

Heberden's nodes are typically found at the distal interphalangeal joints. These nodes are bony enlargements that develop as a result of osteoarthritis, particularly affecting the fingers. The presence of Heberden's nodes is a distinctive feature of this condition and can indicate the progression of joint degeneration.

In osteoarthritis, the cartilage in the joints wears down, leading to bone spurs or growths that manifest as Heberden's nodes. While other types of nodules can occur in different joints of the hands, such as Bouchard's nodes which are found at the proximal interphalangeal joints, Heberden's nodes specifically occur at the distal interphalangeal joints. This distinction is important for diagnosis and understanding the pattern of joint involvement in osteoarthritis.
