Functional Outcome of Collagenase Injections Compared with Fasciectomy in Treatment of Dupuytren's Contracture

Abstract

Background This study was designed to provide comparative information on the safety and efficacy of injection with collagenase clostridium histolyticum (CCH) and fasciectomy for patients with Dupuytren's contracture (DC). Methods A single-center, retrospective, observational, longitudinal chart review was conducted of 25 patients treated with CCH injections and 21 patients undergoing fasciectomy. Patients were assessed at 1 week, monthly for 3 months and then yearly for a minimum of 2 years after treatment for changes in contracture and range of motion, time to return to work/normal activities, patient satisfaction, and Disabilities of Arm, Shoulder and Hand (DASH) score. Results Post-procedure follow-up averaged 32 months for the injection group compared with 39 months for fasciectomy group. For the CCH group, the mean postinjection contracture was 3.6° for the metacarpophalangeal and 17.5° for the proximal interphalangeal joints compared with 3.7° and 8.1° in the fasciectomy group, respectively. Patients treated with injections returned to normal activities after a mean of 1.9 days compared with 37.4 days for fasciectomy patients ( p<0.0001). DASH scores for 13 CCH and 15 fasciectomy patients were obtained. The mean DASH score was significantly lower in the injection group in the first 3 months ( p<0.01). At the 2-year follow-up visit, patients were satisfied with their outcomes following either treatment (92 % and 96 % of CCH and fasciectomy patients, respectively). Conclusion CCH injections are safe and effective and may be a viable alternative to fasciectomy for treating DC. It also allows earlier return to work and daily activities.
