title: [Treatment Methods for Patients with Dupuytren's Disease in Switzerland].
abstract: OBJECTIVE
  The objective of this study was to investigate what treatment options are currently used in Switzerland for Dupuytren's disease. Furthermore, regional preferences and treatment differences based on surgeon experience were analysed.
  
  
  METHODS
  In this survey, an electronic questionnaire was sent to all members of the Swiss Society for Hand Surgery. Participants were asked to indicate their current treatment methods for Dupuytren's disease. In addition, 8 standard patient cases were presented to identify the preferred treatment option. Furthermore, sociodemographic data of the participants were gathered.
  
  
  RESULTS
  In total, 70 questionnaires were completed, corresponding to a response rate of 34%. Fasciectomy is performed by 94% of participants, while 59% inject collagenase in certain cases, 40% perform open fasciotomy, and 24% carry out percutaneous needle aponeurotomy if the indication is given. 20% of responders offer one of these techniques, 50% offer 2, 23% offer 3, and 7% offer all 4 treatment techniques. In the case of isolated metacarpophalangeal joint contracture, 51% of participants inject collagenase, whereas fasciectomy is preferred for the treatment of proximal interphalangeal joint contractures or in cases of recurrence. In German-speaking Switzerland, the treatment strategy has changed towards applying collagenase injections in the past 5 years. In this part of the country, 83% of surgeons now use more collagenase than 5 years ago, whereas only 33% of surgeons in French-speaking Switzerland have changed their treatment strategy in favour of collagenase injections (p=0.027). Surgeons with less than 10 years of experience apply more collagenase than their more experienced colleagues (79 vs. 54%, p=0.131).
  
  
  CONCLUSIONS
  In Switzerland, fasciectomy is the preferred option for treating patients with Dupuytren's disease. In recent years, however, collagenase injection has become more and more popular. More research is needed to define guidelines for the treatment of patients with Dupuytren's disease considering the effectiveness of the different treatment options and regional preferences.
