Vascular Complication after Collagenase Injection and Manipulation for Dupuytren’s Contracture: A Case Report

A case of a vascular complication after collagenase injection and manipulation for Dupuytren’s contracture in a 57-year-old Japanese man is described. The patient presented with a 10-year history of worsening primary Dupuytren’s contracture. The metacarpophalangeal joint of his left little finger had a flexion contracture of 40° and was treated by collagenase injection. When the patient returned to our hospital for manipulation 24 hours later, however, his left little finger was almost completely improved because he hit his finger on the car’s gear lever. Then, 9 months after collagenase injection, in the first winter, he complained of a painful and pale left little finger occurring a few times a day, lasting for about 10 minutes. Now, two years after collagenase injection, the episodes of Raynaud’s phenomenon remain. Although Raynaud’s phenomenon after collagenase injection and manipulation for Dupuytren’s contracture is considered rare, it is a complication to be noted.
