Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • VAS

    Visual analogue scales (VAS) are psychometric measuring instruments designed to document the characteristics of disease-related symptom severity in individual patients and use this to achieve a rapid (statistically measurable and reproducible) classification of symptom severity and disease control. (minimum value is 0 and maximum value is 10)

    Change from Baseline VAS at 6 months

Secondary Outcomes (2)

  • Neck Disability Index (NDI)

    Change from Baseline NDI at 6 months

  • Douleur Neuropathique 4 Questions (DN4)

    Change from Baseline NDI at 6 months

Study Arms (1)

Selective cervical nerve root pulsed radiofrequency

A 5-12 MHz linear US probe was used during the procedure. C7 has a more prominent posterior tubercle and a rudimentary anterior tubercle. C5 and C6 have more prominent and smooth anterior and posterior tubercles, respectively. After visualizing the hypoechoic nerve root between the tubercles of the transverse process, the surrounding vascular structures were identified and RF canula is used. After approaching the hypoechoic nerve root, after sensory and motor stimulation, PRF was applied to each nerve root with a current of 1.0-1.2 V at a frequency of 2 Hz for 4 minutes at 42 °C.

Other: Selective cervical nerve root pulsed radiofrequency
