Comparison of the effect of ketorolac versus triamcinolone acetonide injections for the treatment of de Quervain’s tenosynovitis: a double-blind randomized controlled trial
BMC Musculoskeletal Disorders(2022)
Abstract
Background De Quervain’s disease is tenosynovitis of the first dorsal compartment causing severely painful radial-side wrist pain and impaired function. Steroids are effective in treating this condition due to their anti-inflammatory properties. However, this drug causes problems such as hypopigmentation, and is contradicted in diabetes mellitus patients. Non-steroidal anti-inflammatory drug (NSAID) which are efficacious in shoulder pathology and not contraindicated in diabetics and can be used to avoid the local effects of steroids could be beneficial for some patients. The present study was a randomized controlled trial to examine the differences in pain scores and functional response to local injections of a corticosteroid and the NSAID ketorolac. Methods Sixty-four patients with radial styloid tenosynovitis were randomized using a computer-generated random number table into two groups receiving either a ketorolac injection or a triamcinolone injection. We evaluated post-injection pain intensity using a verbal numerical rating scale (VNRS), functional outcomes using the Thai Disabilities of the Arm, Shoulder and Hand (DASH) scale, and evaluated grip and pinch strengths, recorded at baseline and 6 weeks after the injection. Results Thirty-one participants in the ketorolac group and 29 participants in the triamcinolone group completed the study and were included in the analysis. There were no significant differences in the assessments at baseline. At the 6-week conclusion of the study, patients in the triamcinolone group had a statistically lower average pain score than in the ketorolac group (0.7 ± 2.0 vs 5.3 ± 3.2, P < 0.001), higher DASH functional score (4.4 ± 6.5 vs 34.1 ± 20.2, P < 0.001), higher right grip strength (60.8 ± 16.8 vs 49.2 ± 18.6, P < 0.015), and higher left grip strength (59.8 ± 18.1 vs 50.3 ± 18.0, P < 0.04). However, there was no difference in pinch strength. Conclusions Our study found that ketorolac injections resulted in inferior pain reduction, functional score and grip improvement than triamcinolone injection in patients with radial styloid tenosynovitis. Future studies are required to examine the effects of ketorolac in larger group and with longer follow-up periods to further elucidate the findings of this study. Trial registration The study was registered at Clinicaltrials.in.th (TCTR20200909006).
