Abstract
Epidural steroid injection is thought to reduce inflammatory edema of injured nerve roots, decrease sensitization of dorsal horn neurons, and suppress nociceptive C-fibre transmission. There are two main routes for delivering medication into the cervical epidural space: transforaminal and interlaminar. The transforaminal approach is preferable because corticosteroid preparations can be injected close to the likely source of the irritated nerve root, resulting in better ventral epidural spreading than the interlaminar approach.
Although computer tomography (CT) or fluoroscopy (FL) guidance is the standard assisting procedure for transforaminal approaches, these techniques are time-consuming and expose the patient to radiation. Ultrasound (US), on the other hand, does not expose patients or personnel to radiation and can be performed continuously during the injection.
Several groups have recently demonstrated the dependability of ultrasound (US) guidance for cervical selective nerve root blocks (SNRBs). Because the primary benefit of US is the direct, real-time visualisation of soft-tissue structures, it is especially useful for cervical spine injections, where a plethora of vulnerable vessels and other vital soft-tissue structures are confined to a small area and are frequently in the path of the projected needle trajectory. Furthermore, this widely available method does not emit ionising radiation.
In the present randamized control study we aimed to compare the therapeutic efficacy, safety and advantages of Ultrasound-guided selective cervical intra-tubercular nerve root block (SNRB) versus fluoroscopy-guided cervical interlaminar epidural block (CIEI) in lower cervical radiculopathies through assessment of pain relief and functional improvement.
