AbstractLocal corticosteroid injection into the hand is the preferred initial step in the management of trigger finger owing to its safety and efficacy. We report the case of a patient with shower emboli and digital necrosis after a local corticosteroid injection for the treatment of trigger thumb. Given the patient's subsequent negative hypercoagulability workup, we suspect that the patient's symptoms resulted from the injection of steroids into the princeps pollicis artery, with subsequent retrograde flow into multiple other arteries of the hand. The patient was managed conservatively and ultimately her symptoms resolved. No new areas of digital necrosis have appeared in 8 years of follow-up.
