Dupuytren's contracture is an abnormal thickening and tightening of the normally elastic tissue beneath the skin of the palm and fingers. This tissue is called fascia. The fascia contains strands of fibers, like cords, that run from the palm upward into the fingers. In Dupuytren's contracture, these cords tighten, or contract, causing the fingers to curl forward. In severe cases, it can lead to crippling hand deformities.
