Extra-corporeal shock wave therapy versus local corticosteroid injection in treatment of chronic trigger finger in diabetic patients

Abstract

Background: Trigger finger is one of the most common causes of pain and dysfunction. The aim of our study was to compare the effectiveness of shock wave therapy versus local corticosteroid injection in the treatment of trigger finger in diabetic patients. Results: The two groups were matched on age, HbA1c, VAS score, and grip force at week zero. There was statistically significant improvement in both groups after treatment. In comparing the two groups after 6 weeks of starting treatment either by shockwave therapy or by local corticosteroid injection, there was a statistically significant improvement in group 1 as regards VAS pain score (p = 0.012), clinical signs (finger extension and locking) (p = 0.018), hand grip dynamometer (p < 0.001), and musculoskeletal ultrasound findings in comparison to group 2. Conclusion: Trigger finger is a common complication of DM. Shockwave therapy was able to reduce pain and improve hand functional level and quality of life. Shockwave is an effective, safe, non-invasive method for conservative management of trigger finger.
