Which nodes are associated with Osteoarthritis?

Heberden's nodes and Bouchard's nodes are specifically associated with osteoarthritis. Heberden's nodes occur at the distal interphalangeal (DIP) joints, while Bouchard's nodes occur at the proximal interphalangeal (PIP) joints. Both of these types of nodes are bony enlargements that result from the degenerative changes and osteophyte formation characteristic of osteoarthritis.

In osteoarthritis, the cartilage in the joints wears down, leading to the development of these nodes as a response to joint stress and changes in the bone structure. The presence of these nodes is a clinical indicator of the osteoarthritic process and helps differentiate this condition from other types of arthritis.

Other answer options do not pertain to osteoarthritis. Rheumatoid nodules are associated with rheumatoid arthritis, while gouty tophi are related to chronic gout, and McMurray's sign is a test used for assessing meniscal tears in the knee, not a feature of osteoarthritis.
