Purpose: This study aimed to report pain during and following injection for trigger finger as well as failure to resolve triggering. We hypothesized that a corticosteroid injection alone would be equally or less painful compared with the standard combination of corticosteroid and lidocaine for the treatment of trigger fingers, and there would be no difference in the resolution of triggering.
Methods: Our study was a prospective, single-blinded, randomized controlled trial at a single institution, comprising 76 patients with a diagnosis of trigger finger.
