Durability of Collagenase Treatment for Dupuytren Disease of the Thumb and First Web After at Least 2 Years' Follow-Up.

Purpose: The aim of this study was to analyze the durability of the treatment results of the thumb and first web contractures in Dupuytren disease with collagenase Clostridium histolyticum.
Methods: Twelve patients (14 hands) were followed for an average of 35 months (range, 24-42 months). Two patients (3 hands) were excluded, yielding 11 hands available for assessment. Nondurability was defined as a worsening of at least 20° of passive extension deficit at a treated joint or any decrease greater than 5 mm in intermetacarpal head distance, both relative to 30 days after injection or as intervention to correct new/worsening contracture. Durability was compared with that of a historic cohort of treated finger contractures.
Results: Five out of 11 patients with a metacarpophalangeal or interphalangeal joint contracture or first web contracture had a nondurable result at an average of 35 months. Results obtained at metacarpophalangeal joints of thumbs were more durable than those of interphalangeal joints. Most of the recurrences occurred in interphalangeal joints.
Conclusions: Treatment of thumb and first web contractures was not durable in nearly half of the cases at an average follow-up of 35 months, and durability was clearly less than that of treated finger contractures.
Type of Study/level of Evidence: Therapeutic IV.
