Salman Roghani R, et al. - This triple-blind, randomized, controlled trial was performed to compare the effectiveness of different doses of steroid using the ultrasound-guided hydrodissection method in elderly patients with carpal tunnel syndrome (CTS). In this study, hydrodissection with lidocaine and normal saline was found to have same efficacy as hydrodissection with low- and high-dose steroid medication in elderly patients with CTS.
