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 years; bilateral presentation to include radial digits, plantar fibromatosis (Ledderhose disease), and penile fibromatosis (Peyronie disease) (1).
• Synonyms: morbus Dupuytren; Dupuytren disease; “Celtic hand;” Viking 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 aged >60 years; Spain: 19% of males aged >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 (DM) (Increases with duration of DM, usually mild; middle and ring finger are involved.)
• Excessive alcohol consumption
• Northern European ethnicity
• Family history
• Hand trauma
• Low body weight and BMI

• Occupational hand trauma (vibration)
• Hypercholesterolemia
