If you live with rheumatoid arthritis or psoriatic arthritis and notice your fingers starting to curl toward your palm, it’s natural to wonder whether the two are related.
Both conditions affect the hands. Both can limit how well you grip, type, or button a shirt. So is your arthritis causing your Dupuytren’s disease?
The short answer: probably not. And understanding why matters for getting the right treatment.
What Is Dupuytren’s Disease?
Dupuytren’s disease is a condition of the hand in which thick, fibrous cords form under the skin of the palm, near the tendons.
Over time, these cords can tighten and pull one or more fingers into a bent position. This is called a Dupuytren’s contracture.
Common Signs of Dupuytren’s Disease
- Small lumps or nodules in the palm
- Thick, rope-like cords under the skin
- Fingers (often the ring and pinky) that bend toward the palm and won’t fully straighten
- Difficulty laying your hand flat on a table
- Trouble gripping objects, shaking hands, or putting on gloves
Dupuytren’s is usually not very painful. The main problem is loss of motion and hand function.
What Is Inflammatory Arthritis?
Inflammatory arthritis is a group of conditions in which the immune system mistakenly attacks the body’s own joints and tendons, causing inflammation.
Common types include:
- Rheumatoid arthritis (RA)
- Psoriatic arthritis (PsA)
- Other autoimmune conditions that affect the joints
Common Signs of Inflammatory Arthritis
- Joint pain, swelling, and warmth
- Morning stiffness that lasts longer than 30 minutes
- Fatigue
- Symptoms in multiple joints, often on both sides of the body
These conditions are managed by a rheumatology specialist, who focuses on autoimmune disease treatment and long-term arthritis care.
Why People Suspect a Connection
At Chicago Arthritis, our rheumatologists occasionally see patients who have both inflammatory arthritis and Dupuytren’s disease. That overlap naturally raises the question of whether one causes the other.
There’s another reason the question comes up: Dupuytren’s does have a mild inflammatory component. So it seems reasonable to ask whether the inflammation from RA or psoriatic arthritis could be driving it.
What the Research Shows
Studies that have looked at this question have not found a distinct or definitive connection between:
- Rheumatoid arthritis and Dupuytren’s disease
- Psoriatic arthritis and Dupuytren’s disease
Fibrosis vs. Inflammation: Two Different Processes
The key difference comes down to what’s happening inside the body.
Dupuytren’s disease is mainly a problem of fibrosis, meaning excess scar-like tissue builds up. The chemical signals involved, such as transforming growth factor (TGF), are typically seen in fibrotic conditions.
Inflammatory arthritis is mainly a problem of inflammation, driven by an overactive immune system attacking the joints.
They may both show up in the hands, but they are driven by different biology.
Why This Matters for Your Treatment
This is the most important takeaway:
Treating your inflammatory arthritis will not treat your Dupuytren’s disease.
Even if your RA or psoriatic arthritis is well controlled, your Dupuytren’s can remain a separate issue that needs its own evaluation and care.
Why Dupuytren’s Can Be Harder to Treat
Today, medicine has more effective treatment options for inflammatory conditions than for fibrotic ones. Modern arthritis treatment can calm the immune system and protect the joints.
Fibrotic conditions like Dupuytren’s don’t respond to those same medications. That’s one reason Dupuytren’s tends to be a more stubborn condition than RA or psoriatic arthritis.
What This Means for You
- Keep treating your inflammatory arthritis as prescribed
- Don’t assume your arthritis medication will improve finger contractures
- Tell your doctor if you notice new lumps, cords, or fingers that won’t straighten
- Ask about a separate evaluation and plan for Dupuytren’s disease
When to See a Chicago Rheumatologist
Consider scheduling a visit with a Chicago rheumatologist if you have:
- Joint pain, swelling, or stiffness that won’t go away
- A diagnosis of RA or psoriatic arthritis and new hand changes
- Fingers that are bending and losing motion
- Questions about whether your symptoms are inflammatory, fibrotic, or both
An experienced rheumatology specialist can help sort out which condition is causing which symptoms, so each one is addressed properly.

Conclusion
Dupuytren’s disease and inflammatory arthritis can appear together, and both can affect your hands. But current research shows no definitive link between them.
Dupuytren’s is driven by fibrosis. RA and psoriatic arthritis are driven by inflammation. That means each condition needs its own diagnosis and its own treatment plan.
If you’re dealing with hand changes, joint pain, or an autoimmune condition, the right specialist can help you understand what’s going on and what to do next.
