Dupuytren's Contracture - Comprehensive Management (Limited vs Radical Fasciectomy)

Surgical Indications

Absolute Indications:

• Positive table top test - inability to place palm flat on surface
• MP joint contracture greater than 30 degrees
• ANY PIP joint contracture (even 15-20 degrees warrants consideration)
• Functional impairment - difficulty with grip, activities of daily living

Relative Indications:

• Rapidly progressive disease despite MP contracture less than 30 degrees
• Patient request in younger patients with progressive disease
• Concurrent pathology (Garrod's pads, web space contracture)

Contraindications:

• Medical comorbidities precluding anesthesia
• Unrealistic patient expectations (especially for severe PIP contracture)
• Inability to comply with postoperative therapy and splinting
• Active infection in operative field
• Severe vascular disease compromising healing

Preoperative Assessment

Clinical Examination:

• Table top test: Place hand flat on table - inability = positive test
• Tubiana staging: Measure total flexion deformity at MP + PIP for each ray
  • Stage I: Less than 45 degrees total
  • Stage II: 45-90 degrees
  • Stage III: 90-135 degrees
  • Stage IV: Greater than 135 degrees
• Finger involvement: Ring finger most common (40%), then small (30%), middle (20%), index (10%)
• Skin quality: Assess for adherent skin, puckering, Garrod's pads over PIP joints
• Palpate cords: Identify pretendinous, central, spiral, lateral cords
• Vascular assessment: Allen test, digital perfusion, capillary refill

Dupuytren's Diathesis (Poor Prognosis Factors):

• Age less than 50 years at onset
• Bilateral disease
• Ectopic disease (Ledderhose - plantar, Peyronie's - penile)
• Family history (autosomal dominant with variable penetrance)
• Rapid progression
• Garrod's knuckle pads over PIP joints

Imaging:

• NOT routinely required
• Plain radiographs if concurrent arthritis suspected
• MRI NOT indicated
• Ultrasound for research purposes only

Surgical Planning

Incision Selection:

1. Bruner zigzag: Gold standard for digital incisions - apices at flexion creases, 60 degree angles
2. Z-plasties: Add 75% length where skin tight - plan 60 degree angles
3. Transverse palmar: For McCash open palm technique
4. Combination: Transverse palm with Bruner digits most common

Anesthesia Options:

• Axillary block (preferred for hand surgery)
• Bier's block (IVRA) - acceptable alternative
• General anesthesia if patient preference or block contraindicated
• Wide-awake local anesthesia no tourniquet (WALANT) - emerging technique

Patient Counseling:

• MP contracture: Expect near-complete correction
• PIP contracture: May have 20-30 degrees residual - improves with therapy
• Recurrence: 30-50% at 5 years for stage III-IV disease
• Nerve injury risk: 2-5% (higher with spiral cord)
• Recovery: 8-12 weeks to full function
• Lifelong night splinting may be recommended

Palmar Fascia Anatomy

Normal Anatomy:

• Palmar aponeurosis: Central triangular structure from palmaris longus
• Longitudinal fibers: Eight pretendinous bands to digits
• Transverse fibers: Superficial transverse ligament, natatory ligament
• Sagittal bands: Vertical septa connecting longitudinal fibers to skin
• Spiral bands: Connect palmar fascia to lateral digital sheet and Grayson's ligament

Disease Anatomy - Four Cord Types:

1. Pretendinous Cord (Most Common):

   • Origin: Central aponeurosis
   • Course: Overlies flexor tendon
   • Insertion: Flexor tendon sheath
   • Effect: MP flexion contracture
   • Nerve position: NORMAL - safe dissection

2. Spiral Cord (Most Dangerous):

   • Origin: Pretendinous cord, spiral band, lateral digital sheet, Grayson's ligament
   • Course: Spirals around neurovascular bundle from palmar to radial side
   • Effect: PIP flexion contracture
   • Nerve displacement: THREE directions:
     • CENTRAL (medial) - toward midline
     • SUPERFICIAL - closer to skin, may be subcutaneous
     • PROXIMAL - higher than expected, may be in palm
   • Maximum nerve injury risk

3. Central Cord:

   • Origin: Central aponeurosis in midline palm
   • Course: Midline palm to middle finger
   • Effect: Palmar contracture
   • Nerve position: Usually not involved

4. Lateral Cord:

   • Origin: Lateral aponeurosis
   • Course: Radial side of digit
   • Effect: Radial digital contracture
   • Nerve position: Usually protected

Ligamentous Anatomy:

• Cleland's ligament: Dorsal to neurovascular bundle - protects nerve
• Grayson's ligament: Palmar to neurovascular bundle - involved in spiral cord
• Lateral digital sheet: Connects to spiral band, forms spiral cord
• Natatory ligament: Commissural ligament in web space

Neurovascular Anatomy

Digital Nerves:

• Common digital nerves divide at web space
• Proper digital nerves run palmar to axis of rotation
• Course with digital arteries in neurovascular bundle
• Spiral cord displacement: Central, superficial, proximal

Digital Arteries:

• Common digital arteries from superficial palmar arch
• Divide to proper digital arteries at web space
• Usually run palmar to nerve
• Two arteries per digit - can survive with one if other injured

Superficial Palmar Arch:

• Formed by ulnar artery (dominant) and superficial palmar branch of radial artery
• Located 3-4cm distal to distal wrist crease
• Level of extended thumb
• Gives off common digital arteries

Positioning and Setup

Patient Position:

• Supine on operating table
• Affected upper extremity on radiolucent hand table at 90 degrees abduction
• Ensure adequate padding of bony prominences
• Access to entire arm from shoulder to fingertips

Anesthesia:

• Regional block (axillary or Bier's) preferred
• General anesthesia acceptable
• WALANT (wide-awake local anesthesia no tourniquet) - emerging
• Sedation as needed for patient comfort

Tourniquet Application:

• Sterile or non-sterile tourniquet on upper arm
• Padding beneath tourniquet
• Pressure: 250mmHg (or 100mmHg above systolic)
• Exsanguination: Elevation only (avoid Esmarch if vascular compromise)
• Maximum tourniquet time: 2 hours (typically adequate)

Sterile Preparation:

• Prep entire upper extremity from shoulder to fingertips
• Include hand and all digits in prep
• Chlorhexidine or iodine-based solution
• Drape to expose hand and forearm

Surgical Steps

Step 1: Incision Planning and Execution

Bruner Zigzag Incisions:

• Mark incision with surgical pen before inflation
• Apices at flexion creases (palmar digital crease, PIP crease, DIP crease)
• 60 degree angles from longitudinal axis
• Avoid apices in web space (risk of contracture)
• Extend proximally into palm as needed
• Full-thickness flaps including dermis to subdermal fat junction

Z-Plasty Planning:

• Plan 60 degree angles for 75% length increase
• Central limb along line of contracture
• Two lateral limbs at 60 degrees
• All limbs equal length
• Mark before incision

McCash Open Palm:

• Transverse incision in distal palm
• Perpendicular to longitudinal axis
• Length: 3-4cm typically
• Plan to leave OPEN - counsel patient preoperatively

Incision Execution:

• Use 15 blade for sharp incision through skin
• Raise full-thickness flaps immediately
• Include dermis in flap - thin flaps necrose
• Use skin hooks for retraction (avoid crushing forceps)
• Elevate flaps to expose diseased fascia

Step 2: Identify Normal Anatomy Proximally

Start in Normal Tissue:

• Begin dissection in palm proximal to diseased cord
• Identify normal palmar aponeurosis: white, glistening, longitudinal fibers
• Normal fascia is thin (1-2mm), mobile, soft
• Diseased fascia is thick (5-10mm), adherent, firm, yellow

Establish Anatomic Planes:

• Plane between subcutaneous fat and fascia
• Plane between fascia and underlying flexor tendons
• Use spreading technique with small scissors or forceps
• Gentle traction on fascia to define deep plane

Identify Normal Structures:

• Central aponeurosis in midline
• Pretendinous bands (eight longitudinal bands to digits)
• Sagittal bands (vertical connections to skin)
• Transverse fibers superficially
• This provides roadmap before entering diseased tissue

Step 3: Identify and Classify Disease Cords

Follow Fascia to Disease:

• Trace normal fascia distally to point of thickening
• Diseased cord is firm, thick, yellow, adherent
• May be adherent to overlying skin
• Separate skin from cord if adherent using spreading technique

Classify Cord Type (Critical for Nerve Safety):

1. Pretendinous Cord:

   • Most common
   • Overlies flexor tendon in midline of ray
   • Nerve position NORMAL (radial and ulnar sides)
   • Relatively safe dissection

2. Spiral Cord (DANGER):

   • Look for origin from pretendinous cord
   • Spirals from palmar to radial side around neurovascular bundle
   • Nerve displaced: CENTRAL, SUPERFICIAL, PROXIMAL
   • Maximum nerve injury risk
   • Must identify nerve EARLY

3. Central Cord:

   • Midline palm
   • Usually not involving neurovascular structures

4. Lateral Cord:

   • Radial side of ray
   • Less common
   • Usually safe dissection

Key Decision Point:

• If SPIRAL CORD identified → STOP and identify nerve BEFORE further dissection
• If PRETENDINOUS CORD → can proceed with cord dissection and nerve identification concurrently
• Use loupe magnification (2.5x or 3.5x) for all cord dissection

Step 4: Identify Neurovascular Bundles EARLY

Critical Technique for Spiral Cord:

• Identify nerve BEFORE aggressive cord dissection
• Start proximally in palm where anatomy more normal
• Use GENTLE SPREADING technique with fine scissors
• Look for longitudinal yellow/white structure
• Nerve has longitudinal striations (vs smooth vessel)
• Trace nerve proximally AND distally

Nerve Identification Techniques:

• Look for mesoneurium (thin connective tissue envelope)
• Gentle palpation - nerve feels like firm string
• Test with gentle traction - nerve moves longitudinally
• Artery pulsates (may need tourniquet deflation briefly)
• Use vessel loops to protect identified structures

Nerve Position with Spiral Cord:

• May be CENTRAL (medial) - toward midline of finger
• May be SUPERFICIAL - directly beneath skin, subcutaneous
• May be PROXIMAL - in palm rather than digit
• DO NOT assume normal radial/ulnar position

Protection Strategy:

• Use vessel loops around identified nerves
• Gentle retraction only
• Maintain visualization throughout dissection
• Never lose sight of nerve
• Assistant retracts nerve while surgeon dissects cord

Step 5: Limited Fasciectomy - Cord Excision

Modern Technique (Limited, Not Radical):

• Excise ONLY diseased cord
• Preserve ALL normal fascia
• Preserve ALL neurovascular structures
• Preserve flexor tendon sheath integrity

Palmar Cord Dissection:

• Dissect cord from overlying skin using spreading technique
• Dissect cord from underlying flexor tendons
• Identify and protect neurovascular bundles
• Excise cord from proximal extent to digital extension

Digital Cord Dissection:

• Continue into digit along involved ray
• Spiral cord inserts on lateral digital sheet and Grayson's ligament
• Cord may wrap around neurovascular bundle
• Dissect cord from nerve using spreading parallel to nerve
• Preserve Cleland's ligament (dorsal, protective)
• Excise Grayson's ligament as part of cord (palmar, involved)

Dissection Technique:

• Use small scissors or fine forceps
• Spread parallel to nerve direction
• Gentle traction on cord away from nerve
• Direct visualization at all times
• Loupe magnification essential
• Bipolar cautery for small vessels only

Extent of Resection:

• Proximal extent: Normal fascia in palm
• Distal extent: DIP joint level if involved
• Complete excision of all diseased tissue
• Tag specimens if multiple rays for pathology orientation

Step 6: Address Joint Contracture

Passive Correction Assessment:

• After cord excision, assess passive ROM
• MP contractures usually correct fully (excellent outcomes)
• PIP contractures often persist (capsular contracture)
• Measure residual contracture with goniometer

MP Joint (Usually Full Correction):

• Cord excision usually sufficient
• Rarely need capsular release
• Gentle manipulation acceptable

PIP Joint (Often Persistent Contracture):

• Checkrein ligament release:
  • Accessory collateral ligaments on volar aspect
  • Insert on volar plate
  • Release with curved scissors
  • Bilateral release (radial and ulnar)
• Volar plate release:
  • If checkrein release insufficient
  • Proximal volar plate release from A2 pulley
  • Preserve proper collateral ligaments
• CRITICAL: Do NOT force full extension
  • Risk of flare reaction
  • Acceptable to leave 20-30 degrees residual
  • Will improve with therapy

Flare Reaction (AVOID):

• Severe inflammation, pain, stiffness
• Caused by forced manipulation
• May require stellate ganglion block, therapy
• Prevention: Accept residual contracture

Step 7: Manage Associated Pathology

Garrod's Knuckle Pads:

• Fibrotic thickening over PIP dorsum
• Part of Dupuytren's diathesis
• If adherent to cord → excise with fasciectomy
• If independent → may leave alone
• Defect may require skin graft

Web Space Contracture:

• Release natatory ligament if contracted
• May require Z-plasty for skin lengthening
• Preserve neurovascular structures in web
• Avoid web space narrowing

Thumb Involvement:

• Less common but important
• Release thenar fascia if involved
• Preserve recurrent motor branch of median nerve (thenar)
• May affect thumb IP or MP joint

First Web Space:

• Release if contracted
• Critical for grip function
• Z-plasty commonly needed
• Skin graft if severe

Step 8: Achieve Hemostasis

Tourniquet Release:

• Release tourniquet after dissection complete
• Allow 5-10 minutes for vessel bleeding
• Irrigate with warm saline

Hemostasis Technique:

• Meticulous bipolar cautery
• Avoid excessive cautery near nerves
• Address all bleeding points
• Aim for completely dry field

Check Digital Perfusion:

• Observe capillary refill in all digits
• Check color (pink vs pale/blue)
• Check turgor (full vs collapsed)
• Rarely may have compromised one digital artery - digit usually survives with one

Drain Consideration:

• Consider small Penrose drain if:
  • Extensive dissection
  • Multiple rays
  • Difficulty with hemostasis
• Remove at 24-48 hours

Step 9: Skin Closure Strategy

Digital Incisions (ALWAYS Close):

• Use 4-0 or 5-0 nylon interrupted sutures
• Simple interrupted technique
• Evert skin edges slightly
• No tension on closure
• Ensure adequate skin length (Z-plasty if needed)
• Leave sutures 2 weeks

Palmar Incision (Two Options):

Option 1: McCash Open Palm (Preferred by Many):

• Leave transverse palmar incision OPEN
• Allows drainage, prevents hematoma
• Reduces flare reaction
• Heals by secondary intention in 4-6 weeks
• Well tolerated by patients
• Pack with non-adherent dressing

Option 2: Primary Closure:

• Close with interrupted nylon if:
  • Adequate skin
  • Z-plasties provide length
  • No tension
• Risk of hematoma higher
• Consider drain

Skin Grafting (Rare):

• If large skin defect
• Full-thickness skin graft preferred
• Donor: groin or hypothenar region
• Tie-over bolster dressing
• More common with dermofasciectomy

Step 10: Dressing and Splinting

Dressing:

• Non-adherent dressing over all wounds
• Open palm packed with non-adherent gauze
• Fluffed gauze between digits
• Bulky cotton padding over hand
• Soft bandage wrap (Kerlix)
• Elevation critical

Dorsal Extension Splint:

• Dorsal thermoplastic splint (not circumferential)
• Position:
  • Wrist 30 degrees extension
  • MCPs in full extension (0 degrees)
  • IPs in extension or 10-20 degrees flexion if PIP very stiff
• Extend from mid-forearm to fingertips
• Include all operated digits
• Secure with bandage wrap
• Allow wound inspection without splint removal

Postoperative Instructions:

• Strict elevation above heart for 48 hours
• Ice to forearm (not directly on hand)
• No dependent positioning
• Monitor for excessive pain (compartment syndrome rare but possible)
• Neurovascular checks

Radical Fasciectomy (Dermofasciectomy)

Indications (Limited, Not Routine):

• Severe Dupuytren's diathesis (young age, bilateral, rapid progression, family history)
• Recurrent disease after prior fasciectomy
• Extensively adherent skin requiring excision
• Research suggests possible benefit in diathesis patients

Technique:

• Excision of ALL palmar fascia (diseased AND normal)
• Excision of overlying diseased skin
• Large palmar and digital defect created
• Full-thickness skin graft coverage
• Donor site: groin (preferred) or hypothenar
• Tie-over bolster dressing for 5-7 days

Advantages:

• May reduce recurrence in very high-risk patients
• Removes all potentially diseased fascia
• Addresses severely adherent skin

Disadvantages:

• Higher morbidity than limited fasciectomy
• Donor site morbidity and scar
• Skin graft care and fragility
• Longer recovery (12-16 weeks vs 8-12 weeks)
• Higher complication rate
• NO proven benefit for routine cases

Evidence:

• No randomized trials showing superiority for recurrence
• Observational data mixed
• Modern consensus: Reserve for selected severe cases
• NOT recommended as routine approach

Needle Aponeurotomy (Percutaneous)

Technique:

• Percutaneous cord division using hypodermic needle
• Multiple punctures weaken cord
• Manual manipulation ruptures cord
• Office-based procedure under local anesthesia

Advantages:

• Minimal morbidity
• Office-based
• Rapid recovery
• Low complication rate
• Can repeat

Disadvantages:

• High recurrence (50-85% at 5 years)

• Incomplete correction
• Better for MP than PIP
• Not suitable for spiral cord

Indications:

• Elderly patients with comorbidities
• MP contracture only
• Patient preference for minimally invasive
• Bridging to surgery

Collagenase Injection (Xiaflex)

Technique:

• Injection of Clostridium histolyticum collagenase into cord
• Enzymatic digestion of collagen
• Manual manipulation 24 hours later to rupture cord
• Office-based procedure

Advantages:

• Non-surgical
• Office-based
• Rapid recovery
• Lower short-term morbidity

Disadvantages:

• Moderate recurrence (47% at 5 years for MP, 66% for PIP)
• Expensive
• Risk of tendon rupture (flexor, extensor)
• Risk of CRPS
• Skin tears
• Not suitable for spiral cord

Indications:

• Single cord contracture
• MP contracture preferred
• Patient preference for non-surgical
• Medical comorbidities

Treatment Algorithm

Mild Disease (MP less than 30 degrees, no PIP):

• Observation
• Splinting (unproven efficacy)
• Monitor for progression

Moderate Disease (MP greater than 30 degrees, PIP less than 40 degrees, good surgical candidate):

• Open limited fasciectomy (gold standard)
• Alternative: Collagenase injection if patient preference

Severe Disease (PIP greater than 40 degrees, multiple rays):

• Open limited fasciectomy
• Counsel on realistic outcomes for PIP
• Night splinting critical postoperatively

Severe Diathesis (young, bilateral, rapid, family history):

• Consider radical fasciectomy
• Counsel on higher recurrence risk regardless of technique
• Lifelong monitoring

Recurrent Disease:

• Needle aponeurotomy if mild
• Repeat limited fasciectomy if moderate
• Consider radical fasciectomy if severe/diathesis
• Amputation for severe recurrent PIP contracture (rare)
