Bouchard arthrosis involves which joints?

Explanation:
Bouchard arthrosis denotes osteoarthritis affecting the proximal interphalangeal joints. In OA of the hand, nodal bony enlargements occur at the joints: Bouchard nodes form at the PIP joints, while Heberden nodes form at the DIP joints. That’s why the correct joints involved are the proximal interphalangeal joints. The other joints can be affected by OA in general, but the term Bouchard arthrosis specifically refers to the PIP joints, not the DIP, MCP, or CMC joints.
