Dupuytren's Disease

Dupuytren's disease is a benign fibroproliferative disorder of the palmar and digital fascia. Nodules and cords form in the fascia and draw the digits into a progressive flexion contracture. It is named after Baron Guillaume Dupuytren, who described its surgical treatment in 1831.

Who gets it. Prevalence is highest in populations of Northern European, Celtic or Viking descent, reaching up to 30% in Norwegian men over 60, and it is markedly lower in African, East Asian and South Asian populations. Pooled data from Western, European-ancestry populations give mean prevalences of 12% at 55, 21% at 65 and 29% at 75, rising dramatically with age after 50.

Age and sex. Presentation peaks at 50-60 years, although a patient with a diathesis can present younger. The male-to-female ratio is 7:1 in younger patients and equalises after the age of 70.

Which hand and which finger. The right hand is slightly more often affected, and 40-60% of patients have bilateral disease, which may be asymmetric in severity. The ring finger is involved most often, then the little, middle and index fingers, and the thumb least.

Risk factors. Heredity and Northern European ancestry are the strongest predictor: the pattern is autosomal dominant, and the risk is 15 times higher in Northern European, Celtic or Viking populations. The full list is remembered as DASHED:

• Diabetes mellitus - 20% prevalence in diabetics, against 4% in the general population
• Alcohol - a dose-dependent association, linked to hepatic fibrosis
• Smoking - a 2-3x increased risk, through microvascular effects
• Hereditary / Northern European ancestry - as above
• Epilepsy medication - phenytoin and phenobarbital
• Disease associations - the ectopic fibromatoses: Peyronie (penile), Ledderhose (plantar) and Garrod pads (knuckles)

Dupuytren's diathesis. The term describes an aggressive phenotype with a poor prognosis. The core features are remembered as YBEF, and two more complete the list:

• Young onset, under 40 years
• Bilateral hand involvement
• Ectopic fibromatoses - Peyronie, Ledderhose
• Strong Family history
• Radial-side involvement - index, middle, thumb
• Garrod pads over the dorsal PIP knuckles

Diathesis patients recur more often and may benefit from more aggressive initial surgery (dermofasciectomy). Be careful with a percentage here: no study on this page reports a recurrence rate stratified by diathesis, and figures quoted for it in reviews predate the 2014 consensus definition, so counsel on the direction and the reason rather than on a number.

The normal palmar fascia is organised in four groups:

Pretendinous cord, the most common. It arises from the pretendinous band, runs from the distal palmar crease to the base of the digit and causes MCP contracture. The neurovascular bundle stays in its normal position, and the cord is relatively safe to excise.

Central cord. The continuation of the pretendinous cord into the digit, lying centrally over the flexor sheath and causing PIP contracture. The bundle is in its normal position, and the cord is common in the ring and little fingers.

Spiral cord, the most dangerous. It is built from four components, remembered as PSLG: the pretendinous band, the spiral band, the lateral digital sheet and the Grayson ligament. It spirals around the neurovascular bundle and displaces it centrally and superficially, by up to 1cm from its normal position, which gives it the highest risk of iatrogenic nerve injury and demands careful dissection under loupe magnification.

Lateral cord. It forms from the lateral digital sheet alone and causes PIP contracture. It is less common than the other types, and the bundle is usually in its normal position.

Rarer cords complete the list:

• Retrovascular cord - dorsal to the neurovascular bundle, very rare
• Natatory cord - in the web space, causing web-space contracture
• Thumb cords - first-web pretendinous and proximal commissural cords

The myofibroblast is the central pathological cell. It is a modified fibroblast with a smooth muscle-like contractile apparatus, including stress fibres of alpha-smooth muscle actin (alpha-SMA), and it generates contractile force through actin-myosin interaction. It lays down excessive Type III collagen, where normal fascia is Type I.

The signals. The myofibroblast responds to TGF-beta and to mechanical stress, and several pathways feed the process:

• TGF-beta signalling - the 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 the pathological tissue

Proliferative phase. Myofibroblasts proliferate in a highly cellular tissue of immature fibroblasts and form nodules in the palm and digits. Type III collagen predominates, and the nodules may be painful and progressive.

Involutional phase. The myofibroblasts align along the lines of stress, and cords form from the palmar nodules and extend into the digits. Contracture begins and progresses as the tissue becomes less cellular and more organised, with a transition from Type III to Type I collagen.

Residual phase. A mature, relatively acellular cord of dense Type I collagen bundles holds an established, fixed contracture. There is minimal active disease, and the recurrence risk is low if the cord is excised.

The complaint. A progressive inability to extend the fingers fully, and difficulty placing the hand flat on a surface. Everyday tasks suffer: hand hygiene, putting on gloves, putting the hand in a pocket, fine motor work and gripping tools, and there may be cosmetic concerns or interference with the patient's occupation. It is usually painless, and pain suggests the active proliferative phase.

The course. Onset is insidious, and progression runs over months to years, with periods of rapid progression alternating with stability. The patient may notice a palmar nodule before any contracture develops.

The risk factors. Ask about each risk factor and diathesis feature listed above: ancestry, diabetes and its control, alcohol, epilepsy medication, family history, the other hand, and ectopic fibromatoses.

Look and feel. Palmar nodules are firm, subcutaneous and adherent to the skin, and the skin pits over involved cords. The cords are palpable as longitudinal bands from the palm into the digits; note their consistency, a hard mature cord against a soft nodule. Record which rays are involved, any previous surgical scars and the quality of the skin.

Measure every joint. Measure the MCP and PIP contractures separately with a goniometer, and sum all the joints for the total passive extension deficit. The PIP contracture is the most important for prognosis. Document both active and passive deficits, to rule out joint pathology.

The table-top test (Hueston). The patient tries to place the palm flat on a table, and the test is positive when the palm cannot make flat contact. It indicates a functionally significant contracture and is the traditional threshold for surgery.

Neurovascular baseline. Record digital sensation (light touch and two-point discrimination), capillary refill and colour, and perform an Allen test if there is vascular concern. Document the baseline before any intervention.

Both hands. Always examine both hands, and look for the diathesis features.

A clinical diagnosis. No routine investigations are required: the diagnosis rests on the characteristic palmar nodules and cords with flexion contracture. Imaging is for diagnostic uncertainty or for planning complex revision surgery.

Blood tests. There is no specific blood test for Dupuytren's disease. Screen for diabetes with an HbA1c or fasting glucose if it is not already known, and check liver function if the alcohol history suggests hepatic disease.

Radiographs. They are not routinely indicated for the diagnosis. Take them when joint pathology is suspected (arthritis, a previous fracture or a history of trauma), and before surgery on a severe contracture to assess joint integrity; a fixed PIP contracture warrants a film to look for secondary joint changes.

Ultrasound. High-resolution ultrasound can demonstrate thickened palmar fascia, the identity and extent of a cord, and its relationship to the neurovascular structures, and it may help distinguish Dupuytren's from other masses. It remains mainly a research tool rather than routine clinical practice.

MRI. It is rarely indicated in primary disease and useful for complex cases or diagnostic uncertainty. It can show the full extent of fascial involvement, the relationship to the tendons, neurovascular bundles and joints, and secondary joint pathology. Cords are low signal on T1, and the T2 signal varies with cellularity and phase.

Histopathology. It is not required for diagnosis. Tissue, if obtained, shows myofibroblasts with alpha-SMA immunostaining, Type III collagen predominance early and a transition to Type I late, cellularity that varies with the phase, and no malignant features, since this is a benign process.

Observation. Nodules without contracture, or minimal contracture (less than 30° at the MCP and none at the PIP), are observed, with review of progression every 6-12 months and education about the natural history. No method has been proven to prevent progression.

Corticosteroid injection. Intralesional triamcinolone, 10-40mg injected directly into the nodule, may reduce nodule size in early disease, but the evidence is limited to case series. It can cause fat pad atrophy and skin depigmentation, and it is not effective for established cords.

Radiotherapy. Low-dose radiation, by superficial X-ray or electron beam, may slow progression in the early nodular phase. The evidence is limited and it is not standard of care: it is used in parts of Europe, notably Germany, but not widely adopted elsewhere, and there are concerns about long-term radiation effects.

Splinting. Splinting has no role in preventing contracture progression and may worsen the disease through mechanical stress. Extension splinting after an intervention is a different matter, covered under post-operative care.

CollagenaseNeedle Aponeurotomy

How it works. Collagenase from Clostridium histolyticum (Xiaflex) breaks down the Type I and III collagen of the cord enzymatically, weakening it so that it can be manipulated and ruptured.

Technique.

1. Inject 0.58mg into the palpable cord: at the level of the distal palmar crease for an MCP contracture, at the base or mid-proximal phalanx for a PIP contracture.
2. The patient returns the next day (24-48 hours) for manipulation to rupture the cord under local anaesthetic.
3. Extension splinting follows for 4 months.

Who it suits. An MCP contracture with a palpable cord, preferably a single joint, in a patient who prefers a non-surgical option or whose comorbidity precludes surgery. Allergy to collagenase is a contraindication, and anticoagulation a relative one; multiple joints in the same finger are listed as a contraindication, though they can be treated sequentially.

Outcomes. In Hurst's trial (n=308), 64.0% of collagenase-treated cords reached 0-5 degrees of full extension 30 days after the last injection, against 6.8% with placebo. That is a short-term endpoint, and the comparator was placebo rather than surgery. MCP joints respond better than PIP joints; recurrence is covered with the other treatments under Complications.

Complications. Skin tears are common and usually heal. The others are bruising, swelling and pain, lymphadenopathy, allergic reaction, flexor tendon rupture (rare but reported) and CRPS (rare).

Availability. Collagenase is region-dependent: FDA-approved in the US, it was withdrawn from UK and EU markets in 2020 for commercial reasons despite retained efficacy. Where it is unavailable, needle fasciotomy fills the minimally invasive niche, and cost remains a major access barrier in many health systems.

Technique. Under local anaesthetic in the office or clinic, a 25G hypodermic needle divides the cord percutaneously, in multiple passes that weaken and then divide it. The finger is manipulated once the cord is divided and splinted in extension afterwards.

Who it suits. Elderly patients and those with significant comorbidity, MCP contractures (it works better there than at the PIP), patients who prefer a minimally invasive option, and recurrent disease, since it can be repeated. It is an excellent option for an elderly patient with MCP disease who wants a quick return to function.

Contraindications. A spiral cord, because of the risk of neurovascular injury; a severe PIP contracture; poor skin; and, relatively, anticoagulation.

The trade. It is an office procedure with rapid recovery (days, not weeks), a low complication rate, and it is cost-effective and repeatable. Against that it is less effective for the PIP than the MCP, it cannot address skin deficiency, skin tears are possible, and it has a high recurrence rate (see Complications).

Outcomes. Immediate correction is good: 80-90% achieve an extension deficit of less than 10°. Satisfaction stays high despite recurrence, because the procedure can be repeated.

Complications. Skin tears in 5-10%, digital nerve injury in less than 1%, and rare tendon injury and infection.

Neurovascular injury is the most important complication to avoid. It occurs in 1-5% of fasciectomies, more often with a spiral cord and in revision surgery. The digital nerve is injured most often, because of spiral cord anatomy; a digital artery can also be injured, and bleeding may be the only sign. Prevention is identification of the bundles, loupe magnification and gentle dissection throughout.

If the bundle is injured. Repair the nerve primarily with 8-0 or 9-0 nylon, or graft it if there is a gap. Repair the artery if possible, or ligate it if necessary and check perfusion.

Flexor tendon injury is rare (less than 1%) and occurs while cords are dissected from the flexor sheath; repair it primarily if identified.

Skin flap necrosis. The skin is adherent to the diseased fascia, and thin flaps are at risk. Handle them gently and preserve their blood supply.

Early complications, within 6 weeks.

• Haematoma (2-5%) - prevented by meticulous haemostasis, deflating the tourniquet before closure and a pressure dressing; observe a small one, evacuate a large one
• Wound problems - delayed healing is common with the open-palm technique, which heals by secondary intention; wound breakdown occurs in 5-10%, especially over the PIP, and infection in 1-2%, rare with proper technique. Manage with regular dressings, hand therapy, and antibiotics if infected
• Skin graft loss after dermofasciectomy - partial in 5-10%, complete loss rare (less than 2%); prevented by adequate haemostasis, a secure bolster dressing and immobilisation, and managed by allowing granulation, with a split skin graft if needed

Recurrence or extension. Recurrence is the return of disease in a previously treated area; extension is new disease in a previously unaffected area. Extension represents disease progression rather than true recurrence and is managed as primary disease. The risk factors for recurrence are the diathesis features, young age and PIP involvement.

How often it recurs depends on the definition. The only randomised comparison, of needle fasciotomy against limited fasciectomy found 84.9% against 20.9% at five years, defining recurrence as a total passive extension deficit increase of more than 30 degrees. After collagenase, CORDLESS found 47% of successfully treated joints recurred at five years using a 20-degree threshold, 32% at 30 degrees, with 66% of PIP joints against 39% of MCP joints; that figure is not directly comparable with the needle-fasciotomy one. The five-year ranges in the table below carry no stated definition and cannot be set against those trial figures.

Recurrent disease. Distinguish recurrence from extension, assess severity and functional impact, review the previous operative notes if available, and consider the diathesis features. Observe mild, minimal or asymptomatic disease, and intervene again when it is symptomatic:

• Needle aponeurotomy - repeatable, useful for recurrent MCP disease
• Repeat fasciectomy - technically challenging, with a higher nerve injury risk
• Dermofasciectomy - lower recurrence; consider it in young patients
• Amputation - salvage for a repeatedly recurrent, non-functional digit

Stiffness. Some loss of flexion is common after surgery, and a pre-operative PIP contracture may not fully correct, so realistic expectations matter. Active mobilisation and hand therapy are essential.

CRPS occurs in 5-10%, varying with the definition. Extensive surgery, prolonged immobilisation and nerve injury are risk factors; early mobilisation and gentle surgery are the prevention; and it is managed with hand therapy, pain management and CRPS protocols.

Sensation, scar and pain. Numbness in the distribution of the affected nerves usually improves over 6-12 months and is permanent if a nerve was injured. Scar contracture can occur with inadequate skin coverage: Z-plasty reduces the risk, a skin graft treats deficiency, and hand therapy includes scar massage. Scar tenderness is common initially and usually resolves over time, but a nerve injury can leave neuropathic pain.

The first two weeks. A bulky dressing with an extension splint, elevation to reduce oedema, neurovascular monitoring, and oral analgesia, which is usually sufficient. Change the dressing at 2-3 days if drainage is excessive. Remove sutures at 2 weeks, or leave the wounds open; an open palm needs regular dressings until it heals, at 4-6 weeks.

Early mobilisation starts on day 1-2 after surgery and is critical for the outcome. Active flexion exercises prevent stiffness, and extension is gentle and never forced.

Hand therapy, 2-12 weeks. An essential component of treatment: active range-of-motion exercises, scar massage once the wounds have healed, oedema control with compression and elevation, and progressive strengthening.

Night splinting. A custom thermoplastic splint holds the fingers in extension at night for 3-6 months, maintaining the correction while the tissues heal. It is commonly practised, although the evidence that it reduces recurrence is unclear.

Return to activities. Light activities at 2-4 weeks and heavy activities at 6-12 weeks, individualised to the occupation and healing.

Follow-up. Review at 6 weeks, 3 months, 6 months and 12 months, assessing range of motion, scar and function, monitoring for recurrence as distinct from extension, and educating the patient about the recurrence risk. The full outcome is assessed at 12 months: MCP contractures show excellent correction and low recurrence, PIP contractures more variable correction and higher recurrence, and patient satisfaction is generally high despite the recurrence risk.

• 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:
  1. Check-rein ligaments - divide the two proximal extensions of the volar plate (often the single most effective step).
  2. Accessory collateral ligaments.
  3. Volar plate release from its proximal attachment.
  4. 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.

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.

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

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
