Explanation
Heberden's nodes are bony enlargements that occur at the distal interphalangeal (DIP) joints of the fingers and are a characteristic finding in osteoarthritis. Warm, swollen, and tender joints are typical of inflammatory arthritis conditions like rheumatoid arthritis, not osteoarthritis. Symmetrical joint involvement is more common in systemic autoimmune disorders such as rheumatoid arthritis, not osteoarthritis. A positive Babinski reflex is a neurological finding and is not related to the diagnosis of osteoarthritis.
