Why Is Your Hand Curling? Understanding Dupuytren's Contracture and PRP Treatment

If you've noticed one or more fingers gradually bending toward your palm, you're not alone. This curling of the hand can be an early sign of Dupuytren's contracture, a condition in which the tissue under the skin of your palm thickens and tightens. Below, we'll explain:

• What causes your hand to curl
• How Dupuytren's contracture progresses
• The role of PRP for Dupuytren's contracture
• Other medical next steps
• When to speak to a doctor

Throughout this guide, we use clear language and provide access to a free tool to help you better understand whether your symptoms align with this condition.

What Is Dupuytren's Contracture?

Dupuytren's contracture is a slowly progressing thickening and shortening of the palmar fascia—the connective tissue beneath the skin of your palm. Over time, this can form:

• Nodules: Small, firm lumps under the skin, often near the base of the ring or little finger.
• Cords: Bands of tissue that pull one or more fingers toward the palm.

Common signs include:

• Difficulty straightening fingers fully
• A dimpled appearance on the palm
• Hands that feel less flexible when gripping objects

Who's Most at Risk?

Dupuytren's contracture tends to affect:

• Men more than women
• People over age 50
• Those of Northern European descent
• Individuals with a family history of the condition

Other contributing factors may include diabetes, smoking, alcohol use, and certain medications. However, the exact cause remains unclear—it's likely a mix of genetic and environmental factors.

Why Is Your Hand Curling?

The curling happens because the palmar fascia thickens and loses elasticity. Normally, this tissue allows your fingers to extend and flex smoothly. When it tightens:

1. Fibroblasts (cells that produce connective tissue) become overactive.
2. Collagen fibers accumulate and form nodules and cords.
3. The cords shorten, pulling fingers inward.

This process is painless at first, but over months or years you may notice:

• Stiffness in your palm, especially after rest
• Trouble putting your hand flat on a table
• A gradual increase in finger flexion

Because Dupuytren's contracture doesn't usually cause pain, many people delay seeking help until bending is severe. Catching it early—when cords are just forming—gives you more non-surgical options.

PRP for Dupuytren's Contracture

Platelet-rich plasma (PRP) therapy uses your own blood's platelets, which are rich in growth factors. In theory, injecting PRP into the affected fascia could:

• Modulate inflammation and reduce fibroblast activity
• Encourage tissue remodeling instead of further scarring
• Slow or halt the progression of contracture

How PRP Works

1. A small blood sample is taken from your arm.
2. The sample is spun in a centrifuge to concentrate platelets.
3. The platelet-rich fraction is injected into nodules or along cords.

What the Research Says

• Early studies show PRP may be safe and well-tolerated.
• Evidence for effectiveness in Dupuytren's is limited and mixed; large clinical trials are lacking.
• Most data come from small case series or pilot studies rather than randomized controlled trials.

Because high-quality evidence is still emerging, PRP is considered experimental for Dupuytren's. Your doctor may suggest it alongside other treatments or as part of a clinical trial. If you're interested, ask about:

• Success rates in similar patient populations
• How many sessions are needed
• Cost and insurance coverage
• Potential side effects (bruising, discomfort at the injection site)

Other Non-Surgical and Surgical Options

While research on PRP for Dupuytren's is ongoing, established treatments include:

Non-Surgical Treatments

• Collagenase injections: An enzyme that breaks down the collagen in cords; may reduce contracture by up to 50–80%.
• Steroid injections: Can soften nodules and slow progression in early stages.
• Splinting and physical therapy: Helpful after injections or surgery; may improve range of motion but won't reverse existing contracture.
• Radiotherapy: Low-dose radiation in early stages may soften tissue and delay progression.

Surgical Treatments

• Needle aponeurotomy (percutaneous needle fasciotomy)
  • A minimally invasive procedure using needles to weaken cords.
  • Quick recovery (days to weeks), but contracture may recur sooner.
• Limited fasciectomy
  • Surgical removal of diseased tissue through small palm incisions.
  • Longer recovery (4–6 weeks) but lower early recurrence rate.
• Dermofasciectomy
  • Removal of fascia and overlying skin; skin grafting may be needed.
  • Reserved for severe or recurrent cases.

Your choice depends on contracture severity, age, overall health, and personal preferences.

Next Steps If You Suspect Dupuytren's Contracture

1. Do a free symptom check
   If you're experiencing curling fingers or palm lumps, try Ubie's free AI-powered Dupuytren's Contracture symptom checker to get personalized insights about your symptoms and learn what steps to take next.

2. Monitor progression

   • Track changes in finger angle over weeks or months.
   • Note any new nodules or discomfort.

3. Consult a specialist

   • A hand surgeon or a physician experienced in musculoskeletal conditions can confirm the diagnosis.
   • Imaging (ultrasound) may be used to assess cord thickness.

4. Discuss all treatment options

   • Non-surgical vs. surgical vs. emerging therapies like PRP.
   • Risks, benefits, recovery times, and costs.

5. Plan follow-up

   • Regular check-ups every 6–12 months if you delay intervention.
   • Physical therapy referrals to maintain hand function.

When to Speak to a Doctor Immediately

While Dupuytren's contracture isn't life-threatening, certain symptoms warrant prompt medical attention:

• Severe pain, redness or swelling (could indicate infection)
• Numbness or tingling in the fingers (nerve involvement)
• Rapid worsening of finger bending
• Loss of hand function impacting daily activities

If you experience any of these, call your healthcare provider right away.

Key Takeaways

• Fingers curl in Dupuytren's contracture due to thickening and tightening of palmar fascia.
• PRP for Dupuytren's contracture is an experimental option; early studies show promise but more research is needed.
• Established treatments include collagenase injections, steroid injections, radiotherapy, and various surgical techniques.
• Use a free online symptom checker for Dupuytren's Contracture to evaluate your symptoms and determine if you should seek medical attention.
• Always discuss risks, benefits, and costs with your doctor.

Remember, early detection and a tailored treatment plan can help preserve hand function. If you have concerns about your curling fingers, speak to a doctor—especially if you notice pain, numbness, or rapid changes. Your healthcare provider can guide you toward the best approach, whether that's watchful waiting, PRP therapy, or a more established intervention.
