Contracture de Dupuytren

The base of your thumb, your knuckles, second joint and top joint of your fingers are common sites for hand arthritis. Osteoarthritis, rheumatoid arthritis and psoriatic arthritis are common types.

What is Dupuytren contracture?

Dupuytren contracture (also called Dupuytren disease) is an abnormal thickening of the skin in the palm of your hand at the base of your fingers. This thickened area may develop into a hard lump or thick band. Over time, it can cause one or more fingers to curl (contract), or pull sideways or in toward your palm.

The ring and little fingers are most commonly affected. In many cases, it affects both hands. Rarely, feet may also be affected.

Signes et symptômes

A Dupuytren’s contracture initially may cause only a minor painless lump in the palm of the hand near the base of the finger(s). A Dupuytren’s contracture most commonly affects the ring (fourth) finger and little finger, but it can affect any finger. A Dupuytren’s contracture can also affect one or both hands.

As a Dupuytren’s contracture progresses, it can lead to an inability to fully extend the affected finger from the flexed position. This can result in a loss of normal grasping.

Common symptoms may include:

Not being able to lay your hand flat on a table, palm down (called the tabletop test)
One or more small, sore lumps (nodules) in the palm. Over time, the soreness usually goes away.

• The nodules may thicken and contract or tighten. This can cause thick bands of tissue under the skin in the palm of the hand.
• Pits or grooves in the skin compressed by the contracted finger. These areas can become very sore and can lead to skin loss if they don’t heal well.
• Fingers are pulled forward
• Your hand is not able to work as well
• The symptoms of Dupuytren contracture may look like other health problems. Always see your healthcare provider for a diagnosis.
