Bouchard's nodes are associated with which condition?

• A. Rheumatoid arthritis
• B. Gout
• C. Osteoarthritis
• D. Psoriatic arthritis

Answer: (C)

Bouchard's nodes are bony enlargements at the proximal interphalangeal joints caused by osteophyte formation in osteoarthritis. They reflect degenerative changes in the finger joints, a hallmark of OA that typically affects older adults and joints subjected to repetitive use. These nodal enlargements are classically seen with OA, while other conditions have different hand manifestations (RA with symmetric swelling and MCP involvement, gout with tophi, psoriasis with dactylitis and nail changes), so the presence of Bouchard's nodes points to osteoarthritis.
