A gradual thickening and tightening of tissue under the skin in the hand that causes one or more fingers to bend toward the palm.

Dupuytren contracture can cause one or more fingers to bend toward the palm. It most often affects the two fingers farthest from the thumb. This can make everyday activities, such as placing hands in pockets or shaking hands, more difficult.

The condition starts with a firm lump in the palm of the hand. Over time, the lump can form into a hard cord under the skin and extend into the finger. This cord tightens and pulls the finger toward the palm. The condition most often affects the ring and pinky fingers.

If needed, treatments include using a needle to break the tissue that's causing the finger to bend, enzyme injections to soften the tissue, radiation treatment and surgery.
