Dupuytren Contracture

Basics

Description

  • Palmar fibromatosis; caused by progressive fibrous proliferation and tightening of the fascia of the palms, resulting in flexion deformities and loss of function
  • Not the same as “trigger finger,” which is caused by thickening of the distal flexor tendon
  • Similar change rarely occurs in plantar fascia, usually appearing simultaneously.
  • System(s) affected: musculoskeletal
  • Dupuytren diathesis is an aggressive heritable form associated with age of onset <40, bilateral presentation to include radial digits, plantar fibromatosis (Ledderhose), and penile fibromatosis (Peyronie) (1).
  • Synonyms: morbus Dupuytren; Dupuytren disease; “Celtic hand”; Viking’s disease; palmar fascial fibromatosis, contracture of palmar fascia

Epidemiology

Prevalence

  • Increases with age; mean prevalence in Western countries: 12%, 21%, and 29% at ages 55, 65, and 75 years, respectively. Norway: 30% of males >60 years; Spain: 19% of males >60 years
  • More common in Caucasian men of Scandinavian or Northern European ancestry
  • Mean age of onset is 60 years with typical age range of onset between 40 and 80 years.

Etiology and Pathophysiology

  • Definitive etiology unknown; possibly oxidative stress, altered wound repair, and/or abnormal immune response
  • Occurs in three stages (Luck classification) (1):
    • Proliferative phase: proliferation of myofibroblasts with nodule development on palmar surface
    • Involutional stage: myofibroblasts spread along palmar fascia to fingers with cord development via production of more type 3 collagen
    • Residual phase: fibroblasts are predominant with dense collagen leading to cord tightening and contracture formation

Genetics

  • Autosomal dominant with incomplete penetrance:
    • Siblings with 3-fold risk
  • 68% of male relatives of affected patients develop disease at some time.
  • Possible association with HLA alleles

Risk Factors

  • Smoking (mean 16 pack-years, odds ratio: 2.8)
  • Increasing age
  • Male/Caucasian; male > female (range 3.5:1 to 9:1)
  • Vibration exposure and manual work—risk doubles if regular (weekly) exposure
  • Diabetes mellitus (increases with duration of DM, usually mild; middle and ring finger involved)
  • Excessive alcohol consumption
  • Northern European ethnicity
  • Family history
  • Hand trauma
  • Low body weight and BMI

General Prevention

Avoid risk factors, especially if a strong family history.

Commonly Associated Conditions
