Letter re "Anesthesia for collagenase clostridium histolyticum injection in patients with dupuytren disease: A cohort analysis"

Sanjuan-Cervero et al. 1 report that patients undergoing collagenase injections for the treatment of Dupuytren's contracture report less pain if a wrist block is performed first. Unfortunately the authors did not account for the pain of 10mls of mepivacaine being injected through two injections at the wrist.
