Ultrasound-Guided vs Computed Tomography Fluoroscopy-Assisted Transforaminal Steroid Injections .
Ultrasound-guided Versus Computed Tomography Fluoroscopy-assisted Cervical Transforaminal Steroid Injection for the Treatment of Radicular Pain in the Lower Cervical Spine: A Randomized Single-blind Controlled Noninferiority Study.
Clin J Pain . 2023 Feb 1;39(2):68-75.Four hundred and thirty patients with cervical radicular pain were randomized to receive either an ultrasound-guided (US) transforaminal steroid injection (n=215) or computed tomography (CT) fluoroscopy-assisted cervical transforaminal steroid injection (n=215). Outcomes of interest were contrast spread pattern, the incidence of satisfactory contrast dispersion, pain on a Numerical Rating Scale (NRS), and Neck Disability Index (NDI). Similar pain, disability, and contrast dispersion outcomes were observed between the two groups.
