[Severe contracture of the proximal interphalangeal joint in Dupuytren's disease: does capsuloligamentous release improve outcome?].

Purpose. Evaluation of effectiveness of capsuloligamentous release in severe PIP joint contractures in Dupuytren's disease. Method. Prospective study to compare the clinical outcome of eleven patients with severe contracture of the PIP joint due to Dupuytren's disease, in whom an additional capsulotomy was performed to reduce a residual flexion contracture of the PIP joint of 20 degree and more after release and excision of all diseased fascia, with the outcome of 32 patients with severe contracture of the PIP joint due to Dupuytren's disease, in whom the PIP joint contracture could be reduced by fasciectomy alone. Preoperatively all patients had a severe flexion contracture (60 degrees or greater) of one PIP joint. All patients underwent standardized operative treatment and postoperative extension splinting program for six months. Follow-up examinations included assessment of active range of motion at two, four, ten, 16 and 24 weeks after surgery. Results. In the noncapsulotomy group, preoperative contracture averaged 70.6 degrees and intraoperative residual contracture averaged 2 degrees. In the capsulotomy group, preoperative contracture averaged 78.6 degrees. Intraoperative residual contracture averaged 61.8 degrees before and 2 degrees after capsulotomy. At the final follow-up examination, PIP joint flexion contracture averaged 15 degrees in the noncapsulotomy group compared to 16 degrees in the capsulotomy group. Conclusion. Residual flexion contracture of a PIP joint after release and excision of all diseased fascia in Dupuytren's disease can be reduced by capsuloligamentous release. The data of this study showed no significant differences in the outcome at the final follow-up examination between patients with and without capsulotomy. Therefore, we recommend capsulotomy as treatment of residual flexion contracture of the PIP joint in Dupuytren's disease.
