ObjectiveTo study efficacy and safety of corticosteroid injections for trigger finger (flexor tenosynovitis) in adults in general practice.MethodsAdult patients presenting with trigger finger were recruited by 21 participating general practitioners. In this randomised placebo controlled double-blinded trial, patients were injected locally with one or two injections of 1 ml triamcinolonacetonide (TCA) or 0.9% NaCl. Outcomes regarding immediate treatment response, severity of symptoms, functional disability, patient satisfaction and side effects were measured 1 week after intervention and during the 12 months thereafter.ResultsA total of 50 patients were included. Short-term outcomes for the TCA and NaCl group, respectively, were: proportion of patients with satisfactory immediate treatment response 16/25 and 5/25 (p<0.001), patients with reduction in the frequency of triggering 13/24 and 6/22 (p = 0.053), mean difference in severity of pain 4.2 and 0.9 (p<0.001), patients perceiving improvement 22/25 and 9/25 (p<0.001) and difference in Arthritis Impact Measurement Scale 2 (AIMS-2) score 4.02 and 0.06 (p = 0.001). Long-term effects could only be assessed by analysing the cohort of participants who received TCA (as allocated treatment or escape treatment), due to a high proportion of non-responders in the NaCl group. The short-term beneficial effects were maintained during the follow-up phase of 12 months. Patients were satisfied with corticosteroid injection therapy and there were only a few minor side effects.ConclusionsLocal injection with TCA is effective and safe for treating trigger finger as compared to placebo injection. The effects of steroid injections last up to 12 months.
