Bouchard's nodes

Bouchard's nodes are deformities of the proximal interphalangeal joints of the hand (PIP). Like the Heberden nodes, they are a clinical and graphical sign of osteoarthritis. In contrast to Heberden nodes, nodes caused by antibody deposits in synovial fluid may also correlate with rheumatoid arthritis.

Radiographic findings
In correlation with the clinic, we find bone nodes at the edges of the proximal interphalangeal joints of the hand - they are often palpable (they may correspond to osteophytes), not always painful. They are less common than Heberden nodes.
