Give this one a try later!
Main tissue affected
Results in
- Increased tissue swelling
- Change in colour
- Cartilage fibrillation
- Cartilage erosion down to subchondral bone
descirbe Nodal osteoarthritis due to OA in the hands

, Note bony enlargement of distal and proximal
interphalangeal joints (Herberden's nodes and Bouchard's
nodes, respectively)
occurs most in proximal interphalangeal joint (PIPJ) and
distal interphalangeal joint (DIPJ)
