An Objective Method to Evaluate the Risk of Recurrence and Extension of Dupuytren's Disease

This study was undertaken to assess the influence of the factors related to Dupuytren's diathesis on the rates of recurrence and extension of Dupuytren's disease after surgery. The records of 65 patients who underwent surgery for Dupuytren's disease were retrospectively studied and the presence of factors related to diathesis were recorded. The sensitivity and specificity of each factor for predicting recurrence and extension were calculated. Odds ratios and 95% confidence intervals were also calculated and a discriminant analysis was performed to explore correlations between recurrence and extension and the significant variables. Our results confirmed the prognostic value of diathesis. The results have been used to develop a new scoring system for evaluating the risk of recurrence and extension.
