Anatomy of Dupuytren's Contrac… On the back of the hand, after skin removal, the tendons are seen. On the palm of the hand, after skin removal, a sheet of fibrous gristle or fascia is seen. This fascia is tightly adherent to the skin of the palm and aids in grabbing things (try to grab something with the skin on the back of the hand: it rolls). In the disease of Dupuytren this fibrous gristle or fascia grow and tightens pullling the fingers into a contraction and limiting ability to straighten out the fingers. Underneath this sheet of fibrous tissue on the palm of the hand are the flexor tendons.
