Trigger finger is a tendinitis (stenosing tenosynovitis) with multiple management approaches. We conducted an evidence-based medicine systematic review of level I and II prospective randomized controlled trials to determine the effectiveness of corticosteroid injection in managing trigger finger. MEDLINE, Cochrane database, and secondary references were reviewed to locate all English-language prospective randomized controlled trials evaluating trigger finger treatment. Four studies using injectable corticosteroids were identified, based on the following inclusion criteria: all were prospective randomized controlled trials of adults with >85% follow-up. This review indicates that the incidence of trigger finger is greatest in women (75%), with an average patient age range of 52 to 62 years. Combined analysis of these four studies shows that corticosteroid injections are effective in 57% of patients.
