What is Dupuytren’s Contracture?
Dupuytren’s contracture is a hand condition where thickening of the underlying fibrous tissues of the palm causes the fingers to bend inward. This makes it difficult to fully straighten the affected fingers. It commonly occurs in the ring finger and little finger. Occasionally, the middle finger is affected, but the thumb and index finger are rarely affected.

Diagnosis of Dupuytren’s Contracture
Dupuytren’s contracture is diagnosed based on your history and a physical examination, without the need for any special tests. The physical examination may involve applying pressing on different parts of your hands and fingers to assess for hardened knots or tough bands of tissue.
Conservative Treatment for Dupuytren’s Contracture
- Heat:strong> Applying heat to the palms of your hand prior to massage or exercise can help to loosen the tissues.
- Massage: Gently massage the thickened tissues of the palm.
- Exercises: Stretching exercises such as bending the fingers away from the palm may be useful.
- Injections: Steroid injections in the palm may be administered to relieve local inflammation.
- Collagenase injection: An enzymatic drug that breaks down collagen can be injected into the corded tissue to soften and weaken the contracture. The physician then manipulates the area manually to break up the tissue.
- Needle aponeurotomy: This procedure involves inserting a small needle into the thickened palm tissue and manipulating it to loosen and break up the contracting tissue. Ultrasound may be used to guide the needle to avoid hitting nerves or tendons.
