Background: Triggering symptom is a common problem in patients with trigger finger. Corticosteroid has been found to be effective in the treatment of trigger finger, but not clearly defined in the effectiveness of injection in term of relief triggering symptom. Objectives: The purpose of this study was to investigate the effectiveness of corticosteroid injection in term of relief triggering symptom in patients with trigger finger. Methods: We reported 23 patients with a total of 23 fingers, who were treated by corticosteroid injection for treatment of trigger finger. We tested triggering events in ten active fists for evaluation of triggering symptom before injection and 6 weeks after injection. Clinical data were statistically analyzed by paired t - test or Wilcoxon sign rank test. Results: Most patients in the study were women (22, 95.6 %). The three most commonly affected digits were the thumb (43.5%), the ring finger (34.8%) and the middle finger (21.7%). After corticosteroid injection, the triggering symptom was significantly decreased from 10.00 ± 0.00 to 0.13 ± 0.62 (P < 0.001) at 6 weeks after injection. There were no major complications. Conclusions: Triggering symptom can be treated effectively by corticosteroid injection in the patients with trigger finger. Corticosteroid injection therapy is safe and highly effective.
