Dupuytren's Disease (or simply "Dupuytren's") is a progressive disorder characterized by fibrosis of the palmar fascia. Dupuytren's is associated with the formation of palpable nodules and cords in the palm and fingers. In its later stages Dupuytren's causes fixed digital flexion contractures. Although the disease process spares the tendons deep to the fascia because the contractures place the finger in flexion (as shown in Figure X ) the tendons cannot function normally. Dupuytren’s Disease usually involves the 4th finger but may include others (the 5th finger is next-most likely to be involved; the thumb is least likely). Dupuytren's is rarely a painful condition.
