Babaei-Ghazani A, et al. - This meta-analysis aimed to evaluate the literature and estimate the comparative effectiveness of ultrasound-guided vs. landmark-guided local corticosteroid injections in patients with carpal tunnel syndrome (CTS). The clinicians proposed that compared to landmark-guided injection, the ultrasound-guided injection was more effective in symptom severity improvement in patients with CTS. However, they observed no significant differences in functional status or electro-diagnostic improvements between the two methods.
