This study examines the different application techniques of ultrasound-guided pulsed radiofrequency treatment of cervical spinal nerves for cervical radicular pain. Patients with radiologic imaging findings of C5-C6-C7 disc protrusion or extrusion, with compatible clinical and physical examinations and who have undergone ultrasound-guided spinal cervical nerve radiofrequency treatment in our clinic will be evaluated. Patients' background information will be taken in their files and missing information will be completed by phone call. Pain scores at 3 and 6 months after the procedure will be recorded by scoring from 1 to 10. Patients will not undergo any interventional procedure for research purposes.
