- •7. No previous surgical procedures at the involved level or any planned surgical procedure at the involved or adjacent level other than outlined in inclusion criterion 4,
- •8. Arm Pain score of >= 20 based on Visual Analogue Scale, may be with Preop Neck Disability index score >= 30
- •9. Capable of and willing to comply to the study protocol in the opinion of the Investigator, including a is willingness to return to the hospital for all the required post-operative follow-up visits,
- •10. Capable of and willing to provide voluntary, written informed consent to participate in this investigation and from whom written consent must be obtained prior to enrolment.
- •11. Mild signs of myelopathy without change to the spinal cord as seen on T2-MRI
排除标准
- •a. Arm pain confirmed as non discogenic in origin
- •b. Undergone previous cervical spinal surgery at the index level that could affect the trial outcome (e.g., disc replacement or previous fusion),
