Distal Interphalangeal Joint Changes
Placeholder: DIP joints are the earliest and most common site of hand OA nodules.
- DIP joints: Most common site (Placeholder note)
- Heberden's: Node name (Placeholder note)
- Middle age+: Typical onset (Placeholder note)
- Female: Sex predominance (Placeholder note)
Node formation overview
Placeholder: osteophyte growth at DIP margins produces visible bony bumps.
Proximal Interphalangeal Joint Changes
Placeholder: PIP involvement follows DIP changes and adds mid-finger swelling.
- PIP joints: Site (Placeholder note)
- Bouchard's: Node name (Placeholder note)
- Less common: Frequency (Placeholder note)
- Finger stiffness: Effect (Placeholder note)
PIP node overview
Placeholder: PIP nodules reduce finger flexion range further.
Thumb Base Osteoarthritis
Placeholder: CMC joint OA causes thumb squaring and pinch weakness.
- 1st CMC: Joint (Placeholder note)
- Squared thumb: Sign (Placeholder note)
- Pinch pain: Symptom (Placeholder note)
- Grip decline: Impact (Placeholder note)
CMC involvement overview
Placeholder: thumb base arthritis compounds overall hand disability.
Grip Strength Assessment
Placeholder: dynamometer grip testing tracks functional decline over time.
- Dynamometer: Tool (Placeholder note)
- kg force: Metric (Placeholder note)
- Declining: Trend (Placeholder note)
- Track therapy: Use (Placeholder note)
Grip decline overview
Placeholder: weaker grip correlates with joint severity and pain.
Daily Task Difficulty Index
Placeholder: functional index summarizes difficulty across everyday hand tasks.
- Jar / button / write: Tasks (Placeholder note)
- Severity + grip: Score basis (Placeholder note)
- Care planning: Outcome (Placeholder note)
- AUSCAN-like index: Tool (Placeholder note)
Functional index overview
Placeholder: combined index guides splinting and therapy decisions.
Placeholder: higher combined scores indicate need for splinting and hand therapy.
