Q

What is the treatment of dupuytren’s disease?

A
  • Non operative
    • Observe
    • Radiotherapy
  • Operative
    • Partial fasciotomy (most common procedure in UK)
      • Recurrence 50% at 5 years
    • Dermo-fasciectomy
      • More radical, gets rid of all fascia and removes some skin
      • Requires intensive physiotherapy
    • Arthrodesis
    • Amputation
    • Percutaneous needle fasciotomy
      • Quick and no wounds
      • Higher reoccurrence rate
      • Risk of nerve injury
    • Collagenase
      • Dissolves collagen in the band
      • Major problem is the flexor tendon may rupture
      • Expensive procedure
