About

The purpose of this study is to investigate whether percutaneous needle fasciotomy is as effective for treating Dupuytrens contracture as Xiapex. Immidiate treatment effect is to be investigated, as iskontracture size after 5 years. Contracture size after one and three years, and subjective hand function is also to be investigated.

Full description

Prospective randomized study between Percutanous Needle Fasciotomy and Xiapex for Dupuytrens contracture.

A total of 50 patiens are to be randomized to eighter percutaneous needle fasciotomy or Xiapex treatment.

The patients randomized to xiapex treatment are treated as described in the product manual. Extentin treatment after one day.

The patients randomized to percutaneous needle fasciotomy are treated with the cutting teqnique: A littel quaddle local anestesia (xylocaine with adrenaline) is to be injected subcutant over the cord. After thet we use a 19G needle to cut the cord sufficient number sites to extend the finger.

The patients will be follwed up at 3 weeks, 3 months, 1 year, 3 years and 5 years. Investigators record contracture size, quicq-DASH, pain (VAS) and hand disability (VAS) pretreatment and at all controlls. At 3 weeks investigators register procedure complain. Side effects and complications, and advere effects are also to be investigated.

Our hypothesis is that it is no difference between the two methods in regard of contracture size after five years.

Inclution criteria: Symptomatic primary Dupuytrens contracture with palpable cord in one to three fingers, involving MCP, and total contracture size is over 30 degrees. Patient age over 18 years.

Exclution criteria:
