[Therapy of Dupuytren's contracture with collagenase - Evidence-based Consensus Statement of Austrian Surgical Societies].

Dupuytren's contracture (DC) or Dupuytren's disease (DD) is a progressive fibro-proliferative disease of palmoplantar connective tissue, resulting in characteristic nodal and/or cord formation from collagen disposition. When the disease progresses, the thickening and shortening of the cords eventually leads the affected fingers to being pulled into flexion, which may be associated with marked disability, especially with bilateral disease. DD is relatively common in Europe, with the highest prevalence in Nordic countries. In Austria approx. 200 000 people are affected. The incidence increases with increasing age, with men being more often and earlier affected than women. The aetiology of DC is not completely clear, but it seems to be multifactorial; twin and familial studies confirm a genetic predisposition. The natural course of the disease can vary between relatively benign and massive progression and recurrence. In most cases, there is a fluctuating course. The DC is not curable; treatment methods range from minimally invasive to open surgical procedures. Collagenase Clostridium histolyticum (CCH) is a nonsurgical, enzymatic injection treatment for adult patients (≥ 18 years) with a palpable cord and has been approved in Europe since 2011. Clinical studies and practical experience of individual centres confirm the efficacy and safety of CCH treatment of DC. The present consensus statement was prepared under the auspices of the Austrian Society of Hand Surgery with the participation of the Austrian Society for Trauma Surgery, the Society of Orthopaedics and Orthopaedic Surgery as well as the Society for Plastic, Aesthetic and Reconstructive Surgery. On the basis of current literature and the experts' experience, it describes the various surgical procedures, with particular reference to collagenase treatment and provides guidance for their use. The statement is intended not only to illustrate the state of the art of current treatment, but also to support the achievement of uniform high quality standards in the treatment of DC in surgical centres and specialised medical practices throughout Austria.
