Dupuytren contracture

Symptoms and causes

Dupuytren contracture is a condition that makes one or more fingers bend toward the palm of the hand. Over time, the affected fingers can't fully straighten. This happens because tough tissue under the skin of the palm slowly thickens and shortens into cords that pull the fingers down.

This condition often gets worse slowly, over years. It most often affects the ring finger and little finger, but any finger or thumb can be affected. The limited motion can make everyday activities difficult. These include putting on gloves, shaking hands and reaching into pockets.

There's no cure for Dupuytren contracture. But treatments can relieve symptoms and slow how quickly the condition gets worse.

Dupuytren contracture

Dupuytren contracture is a condition that causes one or more fingers to bend toward the palm of the hand. The affected fingers can't fully straighten. It most often affects the ring finger and little finger.

In Dupuytren contracture, the first symptom typically is a thickening of the skin on the palm of your hand. Over the years, the skin on your palm may look puckered or dimpled, and a firm lump of tissue can form. This lump usually is painless. But sometimes it is painful.

Over time, the lump can form a hard cord that extends into the fingers. The finger is pulled into a bent position. Dupuytren contracture typically affects both hands.

The cause of Dupuytren contracture is not known, but it tends to run in families.
