Ultrasound-guided versus Fluoroscopy-controlled Lumbar Transforaminal Epidural Injections: A Prospective Randomized Clinical Trial.
Recently, most lumbar spine injections have been administered under ultrasound (US) guidance; however, there is no standard method for US-guided lumbar transforaminal epidural injection (TFEI). In this study, we evaluated the accuracy, effect on pain relief, and safety of US-guided lumbar TFEI. ⋯ Lumbar TFEI under US guidance was feasible, safe, and required less radiation to achieve the same benefit as the FL-guided interventions.
