Dupuytren’s contracture

Dupuytren's contracture is a painless thickening and contracture of tissue beneath the skin on the palm of the hand and fingers.
The cause is unknown.
One or both hands may be affected. The ring finger is affected most often, followed by the little, middle, and index fingers.

Treatment

Exercises, warm water baths, or splints may be helpful.

Surgery may be performed to release the contracture, depending on the severity of the condition. Normal movement of the fingers is usually restored by surgery followed by physical therapy exercises for the hand.

A newer treatment involves injecting a substance called collagenase into the scarred or fibrous tissue. Three injections are needed. You may have side effects such as swelling, pain, and itching. A more rare but severe side effect is rupture of the tendon.
