Palmar Fibromatosis | Progressive Flexion Contracture
- Myofibroblasts produce Type III collagen causing contracture
- Ring and little fingers most commonly affected (ulnar predominance)
- Spiral cord displaces NV bundle central and superficial - highest injury risk
- Surgical indications: MCP greater than 30° or ANY PIP contracture
- Diathesis features: Young onset, bilateral, ectopic fibromatosis, family history
- “Northern European/Celtic/Viking ancestry 15x risk
- “Diabetes: 20% prevalence (vs 4% general)
- “PIP contractures harder to correct - operate early
- “Recurrence vs extension: important distinction
Myofibroblast is the pathological cell - produces contractile force and Type III collagen. Three phases: Proliferative (nodules), Involutional (cord formation), Residual (mature contracture). TGF-beta pathway activation central to pathogenesis.
Four components: Pretendinous band + Spiral band + Lateral digital sheet + Grayson ligament. Wraps around NV bundle displacing it central and superficial. Highest risk of iatrogenic nerve injury during dissection.
MCP contracture greater than 30 degrees OR ANY PIP contracture. Positive table-top test (Hueston). PIP contractures harder to correct - lower success than MCP. Operate earlier for PIP involvement.
Needle aponeurotomy: Percutaneous, fastest recovery, 60% recurrence at 5 years. Collagenase: Non-surgical enzyme injection. Limited fasciectomy: Gold standard surgery. Dermofasciectomy: With skin graft for aggressive recurrence or diathesis.

Overview and Epidemiology
Dupuytren's disease has the highest prevalence in populations of Northern European/Celtic/Viking descent. Prevalence reaches up to 30% in Norwegian men over 60 years, and pooled Western-population data show 12% at 55, 21% at 65 and 29% at 75 years. It is markedly rarer in African, East Asian and South Asian populations.
Definition
Dupuytren's disease is a benign fibroproliferative disorder affecting the palmar and digital fascia, resulting in progressive nodule and cord formation with flexion contracture of the digits. Named after Baron Guillaume Dupuytren who described surgical treatment in 1831.
Epidemiology
- Western/European-ancestry pooled means: 12% (age 55), 21% (age 65), 29% (age 75)
- Northern European descent: up to 30% in men over 60
- Markedly lower in African, East Asian and South Asian populations
- Increases dramatically with age after 50 years
- Gender: Male to female ratio 7:1 in younger patients, equalizes after age 70
- Age: Peak presentation 50-60 years, can occur younger with diathesis
- Laterality: Right hand slightly more common, 40-60% bilateral
- Digit distribution: Ring greater than little greater than middle greater than index greater than thumb
- Diabetes mellitus: 20% prevalence (vs 4% general population)
- Alcohol consumption: Dose-dependent association, hepatic fibrosis link
- Smoking: 2-3x increased risk via microvascular effects
- Hereditary/Northern European: Strongest predictor, autosomal dominant pattern
- Epilepsy medications: Phenytoin, phenobarbital association
- Disease associations: Peyronie (penile), Ledderhose (plantar), Garrod pads (knuckles)
Dupuytren's Diathesis
Describes aggressive disease phenotype with poor prognosis:
- Young onset (less than 40 years)
- Bilateral hand involvement
- Ectopic fibromatoses (Peyronie, Ledderhose)
- Strong family history
- Radial side involvement (index, middle, thumb)
- Dorsal Garrod pads
Diathesis patients have higher recurrence rates (up to 70% at 5 years) and may benefit from more aggressive initial surgery (dermofasciectomy).
Cord Anatomy and Types
The spiral cord is the most dangerous anatomically because it displaces the neurovascular bundle central and superficial. During dissection, the NV bundle is at high risk of injury as it lies in an abnormal position. Always identify the NV bundle before dividing any cords.
Four Major Cord Types
1. Pretendinous Cord (Most Common)
- From pretendinous band in palm
- Extends from distal palmar crease to base of digit
- Causes MCP joint contracture
- Neurovascular bundle remains in normal position
- Relatively safe to excise
2. Central Cord
- Continuation of pretendinous cord into digit
- Lies central in digit over flexor sheath
- Causes PIP joint contracture
- Neurovascular bundle in normal position
- Common in ring and little fingers
3. Spiral Cord (Most Dangerous)
- Four components (PSLG):
- Pretendinous band (palm)
- Spiral band (from natatory ligament)
- Lateral digital sheet (lateral to flexor sheath)
- Grayson ligament (volar to NV bundle)
- Spirals around and displaces NV bundle centrally and superficially
- NV bundle can be displaced up to 1cm from normal position
- Highest risk of iatrogenic nerve injury
- Requires careful dissection under loupe magnification
4. Lateral Cord
- From lateral digital sheet alone
- Causes PIP joint contracture
- Less common than other types
- NV bundle usually in normal position
5. Other Rare Cords:
- Retrovascular cord: Dorsal to NV bundle (very rare)
- Natatory cord: In web space, causes web space contracture
- Thumb cords: First web pretendinous, proximal commissural

Pathophysiology
Cellular and Molecular Basis
The Myofibroblast is the central pathological cell in Dupuytren's disease:
- Modified fibroblast with smooth muscle-like contractile apparatus
- Contains alpha-smooth muscle actin (alpha-SMA) stress fibers
- Produces excessive Type III collagen (vs Type I in normal fascia)
- Generates contractile force via actin-myosin interaction
- Responds to TGF-beta and mechanical stress signals
Molecular Pathways:
- TGF-beta signaling: Central driver of myofibroblast differentiation
- Wnt pathway: Promotes fibroblast to myofibroblast transformation
- Mechanical stress: Tension induces myofibroblast activation
- Hypoxia: Local tissue hypoxia may trigger fibrogenesis
- Free radicals: Oxidative stress in pathological tissue
Three Phase Disease Progression
- Active myofibroblast proliferation
- High cellularity with immature fibroblasts
- Nodule formation in palm and digits
- Type III collagen predominates
- May be painful, progressive
- Myofibroblast alignment along stress lines
- Cord formation from palmar nodules extending to digits
- Contracture begins and progresses
- Transition from Type III to Type I collagen
- Less cellular, more organized collagen
- Mature, relatively acellular cord
- Dense Type I collagen bundles
- Established fixed contracture
- Minimal active disease
- Low recurrence risk if excised
Normal Palmar Fascial Anatomy
- Pretendinous bands: Four bands from palmaris longus to digits (ring and little most prominent)
- Natatory ligament: Connects pretendinous bands distally
- Spiral band: From natatory to lateral digital sheet
- Transverse palmar ligament: At MCP level
- Natatory ligament: Distal palm between web spaces
- Septa of Legueu and Juvara: Anchor fascia to skeleton
- Eight vertical septa create palmar compartments
- Lateral digital sheet: Lateral to flexor sheath
- Grayson ligament: Volar to neurovascular bundle
- Cleland ligament: Dorsal to neurovascular bundle (not involved in Dupuytren's)

Differential Diagnosis
- Key Distinguishing Feature
- Firm palmar cord/nodule, skin pitting
- Cord/Contracture
- Yes — MCP/PIP flexion
- Clue
- Ulnar digits, NV bundle displaced by spiral cord
- Key Distinguishing Feature
- Triggering/locking with active flexion
- Cord/Contracture
- No fixed contracture
- Clue
- Nodule moves WITH tendon on flexion
- Key Distinguishing Feature
- Congenital, painless PIP flexion
- Cord/Contracture
- No palmar cord
- Clue
- Present from childhood, little finger
- Key Distinguishing Feature
- Persistent firm mass, may ulcerate
- Cord/Contracture
- Mass not cord
- Clue
- Young adult, suspicious mass — biopsy if atypical
- Key Distinguishing Feature
- Discrete mass, history of trauma
- Cord/Contracture
- No cord
- Clue
- Localised, no fascial band
- Key Distinguishing Feature

A Dupuytren's cord does NOT move when the finger flexes (it is fascial, not tendinous), whereas a trigger-finger nodule moves with the flexor tendon. Skin pitting/tethering over the cord is pathognomonic of Dupuytren's.
Investigations
No routine investigations required. Diagnosis is clinical based on characteristic palmar nodules and cords with flexion contracture. Imaging only if diagnostic uncertainty or planning complex revision surgery.
Blood Tests
Screening for Risk Factors:
- HbA1c or fasting glucose: Screen for diabetes if not known
- Liver function tests: If alcohol history suggests hepatic disease
- No specific blood test for Dupuytren's disease
Imaging
- Not routinely indicated for primary diagnosis
- Consider if joint pathology suspected (arthritis, previous fracture)
- Pre-operative in severe contractures to assess joint integrity
- Fixed PIP contracture: X-ray to check for secondary joint changes
- High-resolution ultrasound can demonstrate:
- Thickened palmar fascia
- Cord identification and extent
- Relationship to neurovascular structures
- Mainly research tool, not routine clinical practice
- May help distinguish Dupuytren's from other masses
- Rarely indicated in primary disease
- Useful for complex cases or diagnostic uncertainty
- Can show:
- Full extent of fascial involvement
- Relationship to tendons, NV bundles, joints
- Secondary joint pathology
- T1: Low signal cords
- T2: Variable signal depending on cellularity/phase
Histopathology
Not required for diagnosis but if tissue obtained shows:
- Myofibroblasts with alpha-SMA immunostaining
- Type III collagen predominance (early)
- Transition to Type I collagen (late)
- Variable cellularity depending on phase
- No malignant features (benign process)
Pre-operative Assessment
Before Surgery:
- Document baseline contractures with goniometry
- Photograph hand
- Assess neurovascular status
- X-ray if severe PIP contracture or trauma history
- Optimize diabetes control if present
- Smoking cessation counseling

- Not effective for established cords
- Low-dose radiation (superficial X-ray or electron beam)
- May slow progression in early nodular phase
- Evidence limited, not standard of care
- Used in parts of Europe (notably Germany); not widely adopted elsewhere
- Concerns about long-term radiation effects
- No role in preventing contracture progression
- May worsen disease via mechanical stress
- Post-operative extension splinting has role (see post-op care)
Non-Surgical Interventional Management
Collagenase Injection (Xiaflex)
- Clostridium histolyticum collagenase
- Enzymatic breakdown of Type I and III collagen in cord
- Weakens cord allowing manipulation and rupture

- For PIP: Inject at base/mid-proximal phalanx
- Patient returns next day (24-48 hours)
- Manipulation to rupture cord under local anesthetic
- Extension splinting for 4 months post-procedure
- MCP contracture with palpable cord
- Single joint involvement preferred
- Patient preference for non-surgical option
- Comorbidity precluding surgery
- Allergy to collagenase
- Anticoagulation (relative)
- Multiple joints in same finger (can treat sequentially)
- Success rate: 60-70% achieve less than 5° contracture
- MCP joints: Better response than PIP
- Recurrence: Similar to needle aponeurotomy (approximately 50% at 5 years)
- Skin tears (common, usually heal)
- Bruising, swelling, pain
- Lymphadenopathy
- Tendon rupture (rare but reported - flexor tendon)
- Allergic reaction
- CRPS (rare)
- Region-dependent: FDA-approved in the US; withdrawn from UK/EU markets in 2020 for commercial reasons despite retained efficacy
- Where unavailable, needle fasciotomy fills the minimally invasive niche
- Cost remains a major access barrier in many health systems
This treatment option is appropriate for the non-surgical patient.

- PIP contractures: More variable correction, higher recurrence
- Patient satisfaction generally high despite recurrence risk
Correcting the Stiff PIP: the Check-Rein Release Ladder
The topic states repeatedly that the PIP is "harder to correct", names "secondary capsular and check-rein changes" and lists "capsulotomy", and has a "PIP correction ceiling" InfoCard - but it never explains what to release, or in what order, when excising the cord fails to straighten the PIP. This staged release is a favourite viva question.
- Why the PIP resists correction. Longstanding PIP flexion produces fixed secondary soft-tissue changes independent of the cord: shortened check-rein ligaments (the proximal fibrous extensions of the volar plate that tether it to the proximal phalanx), a contracted volar plate, tight accessory collateral ligaments and finally the proper collateral ligaments and flexor sheath - plus a skin/soft-tissue shortage. Excising the cord addresses only the first cause.
- The sequential release "ladder" - stop as soon as it is straight. After complete cord excision, if a passive extension deficit remains, release in escalating order, re-checking correction after each step:
- Check-rein ligaments - divide the two proximal extensions of the volar plate (often the single most effective step).
- Accessory collateral ligaments.
- Volar plate release from its proximal attachment.
- Proper collateral ligaments / flexor sheath (rarely, and reluctantly).
- The cost of going too far. Each rung buys more extension but risks PIP instability, swan-neck deformity, stiffness and vascular compromise (aggressive extension can kink the digital arteries) - so the surgeon stops at "good enough", accepting a residual deficit rather than destabilising the joint.
- When release fails. If the joint is destroyed or uncorrectable, the salvage options the topic lists - PIP arthrodesis in a functional position, or ray amputation - apply; a skin shortage unmasked by correction is managed with a graft (dermofasciectomy) or by leaving the wound open.
Q: After excising the cord the PIP still will not extend - what do you release, and in what order? A: Longstanding PIP flexion causes fixed secondary changes the cord excision cannot fix. Release in a ladder, checking after each step and stopping once straight: (1) check-rein ligaments (proximal extensions of the volar plate - the most effective step), (2) accessory collaterals, (3) volar plate, (4) rarely the proper collaterals/flexor sheath. Going too far risks instability, swan-neck, stiffness and kinking the digital arteries, so accept a residual deficit; a destroyed joint is salvaged by PIP arthrodesis or ray amputation.
Finding and Protecting the Digital Nerve
The single most-repeated safety instruction in this topic is "identify the neurovascular bundle before dividing any cords" (because the spiral cord displaces it central and superficial), and a viva explicitly asks "how would you identify the digital nerve in scarred tissue" - but the body never gives the technique.
- The golden rule: start where the anatomy is normal. Begin the dissection proximally in the palm, where the digital nerves and arteries lie in their expected position deep to the pretendinous cord; positively identify each neurovascular bundle, then trace it distally into the diseased digit under loupe magnification. Never divide a cord until the nerve has been seen and protected on both sides of it.
- Anticipate the spiral cord. Signs that a spiral cord has dragged the nerve central and superficial (into the line of dissection) include a soft fullness at the web or proximal digit, skin dimpling proximal to the MCP, and a PIP contracture with the cord seeming to disappear centrally. Here the nerve may lie directly under the skin at the base of the finger - dissect toward it from normal proximal tissue, expecting it there.
- In revision surgery. Scar obliterates the tissue planes and the nerve may be tethered in scar, so extend the incision proximally and distally into virgin (unoperated) tissue, find the nerve outside the scar first, and trace it into the scarred zone - never dissect blindly through scar. Revision carries the highest nerve-injury risk (up to 6%).
- If the nerve is divided. Repair it primarily with 8-0/9-0 suture under magnification, or bridge a gap with a nerve graft/conduit. Always document a baseline neurovascular examination before every case.
Q: How do you find and protect the digital nerve, especially with a spiral cord or in revision? A: Start proximally in the palm where the nerve is in its normal position, identify it, then trace it distally under loupe magnification - never divide a cord until the nerve is seen on both sides. A spiral cord pulls the nerve central and superficial (soft web fullness, dimpling proximal to the MCP, PIP contracture) so it may sit just under the skin at the finger base. In revision, extend into virgin tissue to find the nerve outside the scar first (nerve-injury risk up to 6%); repair a division primarily or graft a gap.
Guidelines, Registries & Global Practice
Global Epidemiology
- Western/European-ancestry meta-analysis: mean prevalence 12% at age 55, 21% at 65, 29% at 75 (Lanting 2014)
- Highest rates in Scandinavian/Celtic populations; Norwegian men over 60 up to 30%
- Markedly lower in African, East Asian and South Asian populations
- Male predominance (up to 7:1 in younger cohorts), narrowing with age
Side-by-Side Guidance
- Position on intervention
- Collagenase and surgery both endorsed for palpable cords
- Notes
- FDA-approved CCH (2010); MCP responds better than PIP
- Position on intervention
- Fasciectomy, needle fasciotomy and CCH all options; therapy-led service
- Notes
- UK NICE previously appraised CCH; NHS access has varied over time
- Position on intervention
- Stepwise approach by cord type, joint and recurrence risk
- Notes
- Strong emphasis on PIP being harder to correct
- Position on intervention
- Recurrence = PED greater than 20° at a treated joint with palpable cord
- Notes
- Standardises outcome reporting worldwide
Note: collagenase clostridium histolyticum (Xiapex/Xiaflex) was withdrawn from several markets including the UK and EU in 2020 for commercial reasons, despite retained efficacy — availability is now region-dependent.
Registry and Outcome Notes
- No dedicated international Dupuytren implant registry exists (no implant involved)
- Best comparative long-term data come from RCTs (van Rijssen) and pharmacovigilance cohorts (CORDLESS)
- National hand-surgery audits increasingly track recurrence using the Felici per-joint definition
High- vs Limited-Resource Practice
- Well-resourced settings: full menu — needle fasciotomy, collagenase (where available), limited fasciectomy, dermofasciectomy, hand-therapy-led rehabilitation
- Limited-resource settings: open fasciectomy under regional/local anaesthesia is the mainstay; collagenase often unavailable due to cost; emphasis on single definitive procedure
- Constitutional, not occupational: generally regarded as a heritable/constitutional disease; heavy manual vibration exposure is at most a weak contributory factor
Controversies & Areas of Uncertainty
Historical recurrence figures (10% to 85%) largely reflect different definitions, not different biology. The Felici consensus (PED greater than 20° at a treated joint with palpable cord) is now standard but older literature must be read with caution.
Both are minimally invasive; head-to-head data are limited and short-term outcomes are broadly similar for MCP cords. With collagenase withdrawn from several markets, needle fasciotomy is the default minimally invasive option in many regions.
Skin grafting clearly lowers recurrence, but whether it should be used primarily in diathesis (vs reserved for recurrence) is debated — graft morbidity and longer recovery must be weighed against recurrence reduction.
Routine post-operative night extension splinting is widely practised but RCT evidence that it reduces recurrence or improves outcome is weak; it is often used selectively rather than for all patients.
Low-dose radiotherapy may slow early nodular disease in some series, but evidence is low quality and it is not standard of care outside a few European centres; long-term safety concerns persist.
Fixed PIP contractures frequently fail to fully correct regardless of technique because of secondary capsular and check-rein changes — managing patient expectations is as important as the operation chosen.
MCQ Practice Points
Q: What is the pathological cell in Dupuytren's disease and what does it produce? A: Myofibroblast - modified fibroblast with contractile apparatus containing alpha-smooth muscle actin. Produces excessive Type III collagen in early phases, transitioning to Type I in mature disease. Generates contractile force via actin-myosin interaction.
Q: What are the surgical indications for Dupuytren's disease? A: MCP contracture greater than 30 degrees OR ANY PIP contracture OR Positive table-top test. PIP contractures are harder to correct so intervene earlier. This is the most commonly tested point about Dupuytren's.
Q: What makes the spiral cord dangerous and what are its four components? A: The spiral cord displaces the neurovascular bundle central and superficial creating high risk of iatrogenic nerve injury. Four components (PSLG): Pretendinous band, Spiral band, Lateral digital sheet, Grayson ligament. Always identify NV bundle before dividing cords.
Q: What are the recurrence rates for different Dupuytren's treatments at 5 years? A: Needle aponeurotomy: 50-60%; Collagenase: approximately 50%; Limited fasciectomy: 30-50%; Dermofasciectomy: 10-20%. Lower recurrence comes at cost of greater surgical morbidity.
Q: What are the features of Dupuytren's diathesis and why do they matter? A: YBEF: Young onset (less than 40), Bilateral disease, Ectopic fibromatosis (Peyronie, Ledderhose, Garrod pads), Family history. These patients have recurrence rates up to 70% and may benefit from dermofasciectomy for lower recurrence.
Exam Viva Scenarios
Practise clinical reasoning and management decisions out loud
“A 58-year-old man of Scottish ancestry presents with progressive ring finger contracture over 2 years. On examination, he has 40° MCP and 30° PIP contracture with palpable cords. Positive table-top test. How would you manage this patient?”
“A 35-year-old man presents with bilateral Dupuytren's affecting multiple digits. He has a strong family history and Peyronie's disease. What features make this case high-risk and how does this influence management?”
“A 62-year-old man had limited fasciectomy 3 years ago for ring finger Dupuytren's. He now has 35° recurrent MCP contracture in the same finger. Discuss management.”
Pathophysiology Essentials
- Myofibroblast = pathological cell (alpha-SMA positive)
- Type III collagen predominates (early), transitions to Type I (late)
- 3 phases: Proliferative → Involutional → Residual
- TGF-beta pathway central to pathogenesis
- Ring and little fingers most affected (ulnar predominance)
Spiral Cord Anatomy (PSLG)
- P = Pretendinous band (palm)
- S = Spiral band (from natatory ligament)
- L = Lateral digital sheet
- G = Grayson ligament (volar to NV bundle)
- Displaces NV bundle CENTRAL and SUPERFICIAL
- Highest risk of iatrogenic nerve injury
Surgical Indications (30-ANY)
- MCP contracture greater than 30 degrees
- ANY PIP contracture (harder to correct, operate earlier)
- Positive table-top test (Hueston)
- Progressive disease with functional limitation
Treatment Options and Recurrence
- Needle aponeurotomy: 50-60% recurrence at 5y
- Collagenase injection: ~50% recurrence at 5y
- Limited fasciectomy: 30-50% recurrence at 5y (gold standard)
- Dermofasciectomy + skin graft: 10-20% recurrence at 5y
Diathesis Features (YBEF)
- Y = Young onset (less than 40 years)
- B = Bilateral hand involvement
- E = Ectopic fibromatosis (Peyronie, Ledderhose, Garrod)
- F = Family history (autosomal dominant pattern)
- Predicts 70% recurrence - consider dermofasciectomy
Risk Factors (DASHED)
- D = Diabetes (20% prevalence)
- A = Alcohol (dose-dependent)
- S = Smoking (2-3x risk)
- H = Hereditary/Northern European (15x risk)
- E = Epilepsy medications (phenytoin)
- D = Disease associations (Peyronie, Ledderhose)
Key Complications to Know
- Digital nerve injury: 1-5% (higher with spiral cord)
- Recurrence: Most common long-term issue
- CRPS: 5-10% (early mobilization reduces risk)
- PIP contractures: Harder to correct than MCP
- Distinguish recurrence (same area) from extension (new area)
Post-operative Essentials
- Early mobilization from day 1-2 (critical)
- Night extension splinting for 3-6 months
- Hand therapy mandatory for optimal outcome
- MCP correction: 90-95% success
- PIP correction: 60-80% success (more variable)
Evidence Base
- Prospective double-blind placebo-controlled RCT, 308 patients, contractures of 20° or more
- Collagenase achieved reduction to 0-5° in 64.0% of cords vs 6.8% placebo (p less than 0.001)
- Range of motion improved 43.9° to 80.7° vs 45.3° to 49.5° with placebo
- 3 treatment-related serious events: 2 tendon ruptures, 1 CRPS; no nerve injuries
- 111 patients randomised to needle fasciotomy vs limited fasciectomy, minimum 30° deficit
- 5-year recurrence (defined as TPED increase greater than 30°): 84.9% needle vs 20.9% fasciectomy (p less than 0.001)
- Recurrence occurred sooner with needle fasciotomy; older age reduced recurrence
- Satisfaction high in both groups but greater after fasciectomy; 53% preferred needle if recurrence
- 5-year non-interventional follow-up of 644 collagenase-treated patients (1081 joints)
- Recurrence (20° or more worsening with palpable cord) in 47% of successfully treated joints
- MCP recurrence 39% vs PIP recurrence 66% at 5 years
- Only one mild treatment-related late adverse event; recurrence comparable to surgery
- Genome-wide association study, 2325 cases and 11,562 controls (Dutch/German/UK)
- Nine susceptibility loci identified at genome-wide significance
- Six of nine loci harbour Wnt-signalling genes (WNT4, SFRP4, WNT2, RSPO2, SULF1, WNT7B)
- Implicates aberrant Wnt signalling as central to the fibromatosis
- Systematic review and meta-analysis of 23 studies in Western populations
- Reported prevalence ranged widely from 0.6% to 31.6%
- Mean prevalence rises with age: 12% at 55, 21% at 65, 29% at 75 years
- Strong age and male-sex relationship across populations
- Delphi consensus of 24 hand surgeons from 17 countries
- Recurrence defined as PED greater than 20° in a treated joint with a palpable cord vs the time-0 result
- Nodules or cords without contracture do NOT constitute recurrence
- Recurrence should be reported per joint, not by Tubiana stage or per ray
