Effectiveness of Percutaneous Needle Aponeurotomy

This study tests the effectiveness of percutaneous needle aponeurotomy (PNA) as a treatment for Dupuytren's disease — a hand condition where fibrous cords develop in the palm and pull the fingers into a bent position that can't be fully straightened. PNA is a minimally invasive office procedure where a doctor uses a small needle to break up these cords through the skin, without surgery. It offers a faster recovery than traditional open surgery but whether it's as effective long-term is still being studied. The study focuses on adults with a confirmed Dupuytren's contracture affecting the main knuckle joint (metacarpophalangeal joint) of at least 20 degrees. Participants will have their hand function and contracture measurements tracked before and after the procedure. You may be eligible if: - You are 18 or older - You have a confirmed Dupuytren's disease with a palpable fibrous cord - You have at least 20 degrees of flexion contracture at a metacarpophalangeal joint - You are covered by social security You may NOT be eligible if: - You have other significant hand conditions like inflammatory arthritis or pain at the affected joint - You have had previous surgery on the same hand that limits movement - You are pregnant or breastfeeding - You are currently enrolled in another interventional trial Talk to your doctor to see if this trial is right for you.
