Dupuytren's contracture is associated with: (1,2)
- manual labour
- uncertainty around the association between Dupuytren's disease and manual labour, in particular the use of vibrating tools
- many authors have linked repetitive hand trauma associated with certain occupations to the development of Dupuytren's disease 
 
 
 - hand trauma
- most experts would concede, however, that a one-off hand injury can rarely trigger Dupuytren's disease and that a history of manual labour indicates a worse prognosis
 
 - epilepsy / treatment with phenobarbitone or phenytoin
- controversy exists as to the significance of either anticonvulsant drugs or epilepsy
 - link between Dupuytren's disease and epilepsy remains unclear, although latest evidence suggests that the association may be due to the effect of certain antiepileptic medications
 
 - Peyronie's disease
 - smoking and excessive alcohol intake are independent risk factors for disease development
- in both cases the relation is dose dependent (odds ratio 1.5-2 for smoking and 1.35-4.2 for alcohol)
 
 - chronic liver disease is not a risk factor independent of alcohol consumption
 - a family history of Dupuytren's contracture
- there is a strong genetic association with study evidence showing up to an 80% heritability
 
 - trauma
 - myxoedema
 - diabetes mellitus
- more prevalent among people with diabetes, especially those dependent on insulin
 - diabetic patients tend to have a milder form of the disease
 
 - hypercholesterolaemia
- patients with Dupuytren's disease have also been noted to have raised serum lipids compared with controls
 
 - AIDS
 
It may also be idiopathic.
Development of Dupuytren's contracture may result from the disturbed metabolism of oxygen-derived free radicals causing fibroblast proliferation and palmar fibrosis.
