Efficacy of 10-mg Triamcinolone Acetonide Local Injection in Patients with Green’s Classification Grade III Trigger Finger at Sangkha Hospital, Surin Province
Keywords:
trigger finger, local steroid injection, Triamcinolone acetonideAbstract
Objective : To study the efficacy of a 10 mg Triamcinolone acetonide local injection in patients with grade III severity according to Green’s classification. Statistical analysis was conducted to determine the relationship between various patient factors and the success of the treatment.
Methods : A prospective pretest-posttest quasi-experimental study was conducted, collecting data from 40 patients with grade III trigger finger between October 1, 2023, and April 1, 2024, who were injected with 10 mg of Triamcinolone acetonide. Follow-up was performed via telephone interviews regarding relief of pain (numerical rating scale NRS), absence of triggering, and complications over a period of 3 months. Data were analyzed using mean, standard deviation, percentage, univariate analysis, and logistic regression, with p-values < 0.05 considered statistically significant.
Results : The efficacy in reducing pain and resolving triggering was highest at 6 weeks, but its effectiveness tends to decrease over time. The success rate at 6 weeks was 92.5%, and at 3 months it was 75%. There were no reports of serious complications. Factors such as gender, age, affected finger, duration of symptoms before treatment, dominant hand and prior use of NSAIDs did not show a statistically significant correlation with treatment outcomes.
Conclusion : A 10 mg Triamcinolone acetonide local injection in patients with grade III trigger finger is safe and provides the best treatment outcomes at the 6-week post-injection mark.
