Pulley Rupture in Rock Climber after Collagenase Treatment for Dupuytren Contracture.

Pulley injuries and Dupuytren disease are quite common in rock climbing. We report a rock climber who was treated for a Dupuytren contracture with collagenase injection therapy. Two months later, he developed a traumatic pulley injury during climbing and was treated with a ring orthosis. However, the finger contracture deteriorated and both a recurrent pulley rupture and a second pulley rupture were diagnosed. We were unable to find any reports on the use of collagenase in rock climbers with Dupuytren disease. We report a case of pulley rupture in a rock climber, treated for Dupuytren contracture in the treated and an adjacent finger, 2 months after the injection of collagenase. Level of Evidence: Level V (Therapeutic).
