Because of high recurrence rates, new surgical techniques were introduced, such as fasciectomy and then dermofasciectomy. Most of the diseased tissue is removed with these procedures.Recurrence rates are low. For some individuals, the partial insertion of "K-wires" into either the DIP or PIP joint of the affected digit for a period of a least 21 days to fuse the joint is the only way to halt the diseases progress. After removal of the wires, the joint is fixed into flexion, which is considered preferable to fusion at extension. In extreme cases, amputation of fingers may be needed for severe or recurrent cases or after surgical complications. Limited fasciectomy
Limited/selective fasciectomy removes the pathological tissue, and is a common approach. Low-quality evidence suggests that fasciectomy may be more effective for people with advanced Dupuytrens contractures.During the procedure, the person is under regional or general anesthesia. A surgical tourniquet prevents blood flow to the limb. The skin is often opened with a zig-zag incision but straight incisions with or without Z-plasty are also described and may reduce damage to neurovascular bundles. All diseased cords and fascia are excised. The excision has to be very precise to spare the neurovascular bundles.
Moderate pressure for 10–20 seconds ruptures the cord.After the treatment with collagenase the person should use a night splint and perform digital flexion/extension exercises several times per day for 4 months.In February 2010 the US Food and Drug Administration (FDA) approved injectable collagenase extracted from Clostridium histolyticum for the treatment of Dupuytrens contracture in adults with a palpable Dupuytrens cord. (Three years later, it was approved as well for the treatment of the sometimes related Peyronies disease.) In 2011 its use for the treatment of Dupuytrens contracture was approved as well by the European Medicines Agency, and it received similar approval in Australia in 2013. However, the Swedish manufacturer abruptly withdrew distribution of this drug in Europe and the UK in March 2020 for commercial reasons. (It now is promoted primarily as a dermatological treatment for cellulite aka "cottage cheese thighs"). Collagenase is no longer available on the National Health System except as part of a small clinical trial. Radiation therapy
Radiation therapy has been used mostly for early-stage disease, but is unproven. Evidence to support its use as of 2017, however, was scarce —efforts to gather evidence are complicated due to a poor understanding of how the condition develops over time. It has only been looked at in early disease. The Royal College of Radiologists concluded that radiotherapy is effective in early stage disease which has progressed within the last 6 to 12 months. Alternative medicine
Several alternate therapies such as vitamin E treatment have been studied, though without control groups.
