Overview
Brief Summary
This study aims to compare the efficacy of ultrasound-guided selective cervical nerve root pulsed radiofrequency (PRF) versus fluoroscopy-guided paramedian cervical epidural steroid administration (CESI) for the treatment of lower cervical radicular pain refractory to conservative treatments. For this evaluation, a numerical rating (NRS), neck disability index (NDI), and Leeds Assessment Of Neuropathic Symptoms And Signs (LANSS) scale will be used before and after both interventions.
Detailed Description
Chronic cervical radicular pain is a common condition that affects the quality of life of many patients and is caused by compression or irritation of the cervical nerve roots. Treatment options for this condition include conservative methods such as medications and physical therapy, as well as interventions such as surgery or injections. Two commonly used injections for chronic cervical radicular pain are ultrasound-guided selective nerve root PRF and fluoroscopy-guided paramedian CESI. PRF involves the application of pulsed radiofrequency energy (intermittent current, tissue temperature not exceeding 42 °C) to the cervical nerve root under ultrasound guidance. PRF is a non-destructive technique that modulates the activity of nerve fibers without causing thermal damage. CESI involves injecting local anesthetic and steroids into the epidural space between the laminae of the vertebrae under fluoroscopic guidance. The aim of both techniques is to reduce inflammation and pain transmission from the affected nerve root. The efficacy of both CESI and selective nerve root PRF has been demonstrated in clinical trials. The primary aim of the investigators in this study is to compare the efficacy of these two treatments. A total of at least 60 patients, 30 patients in each group, will be enrolled for comparison. NRS, NDI, and LANSS scores before, 3 months, and 6 months after treatment will be compared both within and between groups. The secondary aim is to reveal the side effects and adverse events in these two treatment modalities.

Outcomes
Primary Outcomes
Numerical rating scale (NRS)
Time Frame: Change from baseline to 3rd and 6th month after treatment
NRS is a scale that can be used measuring pain. Scores range from 0 (no pain) to 10 (the worst pain)
Secondary Outcomes
- The Neck Disability Index (NDI)(Change from baseline to 3rd and 6th month after treatment)
- Leeds Assessment Of Neuropathic Symptoms And Signs (LANSS)(Change from baseline to 3rd and 6th month after treatment)
