OA: primary vs secondary

secondary= known cause (trauma, malformations, etc)

2

OA: Heberden's vs Bouchard's nodes

Heberden's = at the DIP

Bouchard's = at the PIP

3

Knee OA criteria

-persistent pain
-limited morning stiffness
-reduced function
-crepitus
-boney enlargement
-restricted movement

4

RA: pathology

-immune cells into synovial
-thickens
-dec joint lube and articular cartilage nutrition
-weakens the joint

RA: swan neck vs boutonniere deformity

Swan = extend PIP, flex DIP
