Correct option is D
Bouchard’s nodes (at the proximal interphalangeal joints) and Heberden’s nodes (at the distal interphalangeal joints) are characteristic signs of osteoarthritis (OA). These nodes form due to bony overgrowth and joint degeneration, often resulting in stiffness and reduced range of motion. OA is a non-inflammatory joint disorder caused by wear and tear of cartilage.
Explanation of options: (a) Rheumatoid arthritis – Involves inflammation and deformity, typically affecting metacarpophalangeal joints, but not associated with bony nodes like in OA. (b) Gout arthritis – Characterized by tophi and acute joint inflammation, especially of the big toe, not nodular changes in fingers. (c) Infective arthritis – Caused by infection, presents with joint swelling, pain, and systemic symptoms, without formation of nodes. (d) Osteoarthritis – This is the correct answer. It features joint space narrowing, osteophyte formation, and characteristic nodes at finger joints.
