Dupuytren’s contracture /dYpY·itraNs″, dēpē·itranz″/ [Guillaume Dupuytren, French surgeon, 1777–1835; L, contractura drawing together] , a progressive, painless thickening and tightening of subcutaneous tissue of the palm, causing the fourth and fifth fingers to bend into the palm and resist extension. Tendons and nerves are not involved. Although the condition begins in one hand, both become symmetrically affected. Of unknown cause, it is most frequent in middle-aged males. Early surgical removal of the excess fibrous tissue under general anesthesia restores full use of the hand. An incision is made in the palm, and the thickened tissue is excised carefully to prevent injury to adjacent ligaments.
