What matters most
Hand OA is not just “wear and tear.”
What often drives symptoms is the combination of:
- flare inflammation
- subchondral bone activation
- impaired pinch and grip mechanics
That is why function matters at least as much as imaging.
1) What is happening medically?
Typical drivers include:
- mechanical overload, especially at the thumb base
- synovitis during flares
- subchondral bone sensitivity
- osteophytes and deformity over time
Pain does not correlate 1:1 with the X-ray.
2) Common patterns
- Thumb base OA / CMC-1 OA
- DIP OA / Heberden pattern
- PIP OA / Bouchard pattern
- STT OA
- Mixed hand OA patterns
3) Differential diagnoses
- Rheumatoid arthritis
- Psoriatic arthritis
- Crystal arthropathy / gout
- De Quervain tendinopathy
- Trigger finger
- Carpal tunnel syndrome
4) Typical symptoms
Common complaints include:
- Thumb-base pain with key pinch
- Trouble opening bottles or jars
- Finger nodes and stiffness
- Flare-like pain
- Reduced pinch strength
- Reduced grip strength
What patients care about most is usually not the image.
It is function:
- Can I turn a key?
- Can I open a bottle?
- Can I hold cutlery?
- Can I carry a bag?
5) Red flags
Medical review is needed for:
- A hot red joint
- Fever
- Marked deformity after trauma
- Persistent inflammatory night pain
- Dominant nerve symptoms
6) Course
Hand OA often runs in flares.
Without a plan, many patients get stuck in a loop:
splint → short relief → force loss → recurrence
7) Diagnostics
Often the clinical pattern comes first.
Key questions:
– Where is the pain exactly?
– What does the hand fail to do?
– Is this OA, tendon, nerve, crystal or inflammatory disease?
Imaging or lab work is added selectively.
8) Treatment options
- Orthosis selectively
- Flare control
- Targeted hand therapy
- Pinch and grip rebuilding
- Joint protection
- Everyday adaptation
The weak point of standard care is often not effort, but lack of sequencing.
9) When a structured program makes sense
A more structured program often makes sense when:
- thumb-base or finger pain persists
- function is clearly limited
- flares keep recurring
- the differential diagnosis remains unclear
- you want a force-and-function roadmap, not isolated measures
