Chronic cervical pain is a common disorder with a prevalence of approximately 35% in adults. Cervical radicular pain is defined as radiating pain in the upper limb caused by compression or inflammation of the nerve roots ascending from the intervertebral foramen to the spinal cord, due to disc herniation or spinal stenosis. C7 and C6 are the two most commonly affected nerve roots. Various treatment modalities are available, including oral medications, physiotherapy, and epidural steroid injections. However, chronic and persistent pain that develops as a result of some patients not responding to these treatments. Ultrasound-guided selective cervical nerve root block and pulsed radiofrequency are interventional treatments used in patients with radicular cervical pain unresponsive to conservative treatments. Pulsed radiofrequency (PRF) treatment of peripheral nerves may provide long-term pain relief in patients with short-term pain relief with a local anesthetic block. Studies have shown the effectiveness of PRF therapy applied to selective cervical nerve roots in relieving cervical radicular pain.
