Ultrasound-Guided Pulsed Radiofrequency for Chronic Cervical Radicular Pain

Cervical radicular pain, often resistant to conservative treatments, poses a significant challenge in patient management. This study aimed to evaluate the efficacy of ultrasound-guided selective cervical nerve root pulsed radiofrequency (US-SCNR PRF) in patients with chronic cervical radicular pain due to cervical disc herniation who did not respond to traditional treatments. A total of 62 patients underwent US-SCNR PRF treatment, and pain intensity was assessed using the Numerical Rating Scale before and at 1, 3, and 6 months after the procedure. Additionally, functionality and neuropathic pain were measured using the Neck Disability Index and the Douleur Neuropathique 4 Questions, respectively, both before and 6 months after the treatment. Significant pain relief was defined as a 50% or greater reduction in pain scores compared to pre-treatment levels. The results showed a significant reduction in cervical radicular pain at 1, 3, and 6 months post-treatment, with 59.6% of patients achieving successful pain relief at the 6-month mark. However, the difference in pain scores between the 1st, 3rd, and 6th months was not significant. Additionally, functionality and neuropathic pain scores improved significantly after 6 months. These findings suggest that US-SCNR PRF treatment offers effective pain relief, improved functionality, and reduced neuropathic pain for at least six months in most patients with refractory cervical radicular pain. The treatment is considered safer and preferable due to real-time visualization of cervical nerve roots, adjacent neurovascular structures, and the absence of radiation exposure, making it a promising option for managing chronic cervical radicular pain.
