About

The main objective is to investigate if percutaneous needle aponeurotomy is non-inferior to open surgery using aponeurectomy in treatment of flexion contracture due to Dupuytren's disease.

Our hypothesis is that percutaneous needle aponeurotomy has suitable efficacy and safety profile for large application in the treatment of Dupuytren's disease and that it is consequently able to drastically reduce the need of open surgery in this indication.

Full description

Scientific justification:

Dupuytren's disease is a world-wide musculoskeletal disorder. It consists in fibrosis of the palmar aponeurosis that can induce disabling flexion contracture of the metacarpophalageal or proximal interphalangeal joints. Treatment modalities of flexion contracture include open surgery, percutaneous needle aponeurotomy and collagenase. Collagenase is not available in France. Aponeurectomy, that is also called fasciectomy, is the main open surgical technique, and open surgery is the most frequently used treatment in Dupuytren's disease. Percutaneous needle aponeurotomy is recommended as a nonsurgical treatment for Dupuytren's disease. It is a minimally invasive procedure. Its most largely accepted indication is Dupuytren's disease with metacarpophalageal joint involvement. However, percutaneous needle aponeurotomy has been successful for metacarpophalageal or proximal interphalangeal joint involvement, in nonadvanced and in advanced Dupuytren's disease. A model analysis recently demonstrated that replacing open surgery with percutaneous needle aponeurotomy could save more than 50% of the total hospitalization costs for the disease.

Percutaneous needle aponeurotomy therefore appears as a unique minimally invasive approach for Dupuytren's disease. It could become a valuable alternative to open surgery. The hypothesis is that percutaneous needle aponeurotomy has suitable efficacy and safety profile for large application in the treatment of Dupuytren's disease and that it is consequently able to drastically reduce the need of open surgery in this indication.

Practical procedure:

Patients addressed to the consultation of the hand surgery centers for Dupuytren's disease will be prospectively selected, included, randomized, treated using percutaneous needle aponeurotomy or open surgery within six weeks after randomization, and followed at 1 week, 1, 3,12, 24 and 36 months after treatment. Assessment of efficacy will be blinded. Assessment of complications will be done by an unblinded assessor.

---

120 participants in 2 patient groups

Percutaneous needle aponeurotomy

Experimental group

Description:

It consists in cutting the fibrotic cord due to the disease and responsible for the flexion contracture, with a needle under local anesthesia. The procedure can be repeated as required during the same session. One to three sessions with at least one-week interval are usually sufficient and will be allowed. It will be performed in outpatient setting by a senior physician experienced in the procedure. End of treatment will be considered as the last session of needle aponeurotomy.

Treatment:

Procedure: Percutaneous needle aponeurotomy

Open surgery with limited aponeurectomy

Active Comparator group

Description:

It consists in excision of the fibrotic aponeurosis.It will be performed by hand surgeons under loco-regional anaesthesia during a short hospitalization (1 day stay). Post-operative cares are necessary (analgesics, splint, nursing, physiotherapy). End of surgical treatment will be considered as the removal of the stitches (two weeks after the surgical treatment).

Treatment:

Procedure: Open surgery with limited aponeurectomy
