Dupuytren's contracture

Dupuytren's contracture of the ring finger

Dupuytren's contracture (also called Dupuytren's disease, Morbus Dupuytren, Viking disease, palmar fibromatosis and Celtic hand) is a condition in which one or more fingers become permanently bent in a flexed position. It is named after Guillaume Dupuytren. It usually begins as small, hard nodules just under the skin of the palm.
