Finger Joint Contractures 5 Years After Treatment for Dupuytren Disease: A Comparative Cohort Study of Collagenase Injection Versus Surgical Fasciectomy

J Hand Surg Am. 2022 Sep;47(9):834-842. doi: 10.1016/j.jhsa.2022.04.019. Epub 2022 Jul 20.


Purpose: To compare collagenase injection with surgical fasciectomy in Dupuytren disease (DD) for the prevalence of contracture in treated fingers 5 years after treatment.

Methods: This was a single-center, comparative cohort study comprising 2 cohorts of patients treated for DD in 1 or more of 3 ulnar fingers with collagenase injection (159 patients) or surgical fasciectomy (59 patients). At 5 years after treatment, 13 collagenase-treated and 8 fasciectomy-treated patients had undergone subsequent treatment on the treated fingers and were considered to have current contracture. Of the remaining patients, 112 collagenase-treated patients (128 hands, 180 fingers) and 46 fasciectomy-treated patients (49 hands, 63 fingers) attended follow-up evaluation performed by 2 independent examiners (participation rate 84% and 93%, respectively). We defined current contracture in a treated finger as an active extension deficit of ≥20° in the metacarpophalangeal (MCP) or proximal interphalangeal (PIP) joint or a total (MCP + PIP) active extension deficit (TAED) of ≥30°. We used linear mixed models to analyze differences between the cohorts over time.

Results: In the collagenase cohort, current contracture was present in 45 (25%) MCP and 60 (33%) PIP joints, and in the fasciectomy cohort, current contracture was present in 12 MCP (19%) and 30 PIP (48%) joints; a TAED of ≥30° was present in 79 (44%) of the collagenase-treated and 30 (48%) of the fasciectomy-treated fingers. In MCP and PIP joints with ≥20° pretreatment contracture, complete correction was observed in 82 (56%) MCP and 30 (30%) PIP joints in the collagenase cohort and 23 (70%) MCP and 5 (16%) PIP joints in the fasciectomy cohort. There was no statistically significant difference between the 2 cohorts in the TAED change over time.

Conclusions: In patients with DD, collagenase injection and surgical fasciectomy improved finger joint contracture over the pretreatment status but had a high prevalence of joint contracture in the treated fingers 5 years after treatment.

Type of study/level of evidence: Therapeutic IV.
