研究概要

Sixty patients with trigger finger were randomized to receive a single corticosteroid injection with a full-time static splint at the metacarpophalangeal joint (3 months) (n=30) or a single corticosteroid injection alone (n=30). The primary outcome of interest was the Numeric Pain Rating Scale (NPRS). Secondary outcomes of interest included Boston questionnaire scores for symptom severity and functional status, grip strength, and the stages of stenosing tenosynovitis. Outcomes were measured at 1 and 3 months follow-up. The results revealed significantly greater improvements in pain, symptom severity, and disease severity after 3 months in the splint group. Improvements in grip strength were significantly greater in the splint group at 1 month and trended towards statistical significance at 3 months (p=0.056).
