- Symptoms and signs of the patients were typical. MRI showed single or multiple central herniation of C3-C7 intervertebral discs or spinal stenosis at corresponding levels, which confirmed cervical myeloid cervical spondylosis or cervical spinal stenosis.
- Conservative treatment for more than 3 months before surgery was ineffective.
- The patients underwent cervical single open-door surgery.
- Informed consent was obtained from the patient and his family, informed consent was signed, and a complete follow-up was completed after surgery
- Cervical spondylotic radiculopathy.
- Cervical kyphosis or instability.
- Cervical spondylosis caused by trauma, tumor, tuberculosis and metabolic diseases.
- Revision surgery or combined anterior-posterior surgery is required.
- The patients had severe neurological diseases affecting the evaluation of postoperative results.
- Psychopath.
- MRI or CT for contraindications.

NDI score change pre-operation,3 months after surgery, 1 year after surgery Neck Disability Index (NDI) score is used to assess the disorder of spinal cord which is in the form of questionnaires. Postoperative improvement rate = (total score)/ (numbers of programme X5) X100%. Improvement rate can also correspond to the commonly used efficacy criteria: the improvement rate when 60%-80% means extremely severe dysfunction, when 40%-60% means severe dysfunction, when 20-40% means moderate dysfunction, and when less than 20% means mild dysfunction.
VAS score change pre-operation,3 months after surgery A Visual Analogue Scale (VAS) is used to measure the amount of pain that a patient feels ranges across a continuum from none to an extreme amount of pain. Using a ruler, the score is determined by measuring the distance (mm) on the 10cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
JOA score change pre-operation,3 months after surgery, 1 year after surgery Japanese Orthopedic Association (JOA) score is used to assess the function of spinal cord which is in the form of questionnaires. Postoperative improvement rate = ((postoperative score - preoperative score)/ (17- preoperative score)) X100%. Improvement rate can also correspond to the commonly used efficacy criteria: cure when the improvement rate is 100%, effective when the improvement rate is greater than 60%, effective when 25-60%, and ineffective when less than 25%.
- Secondary Outcome Measures
Name Time Method Compression ratio change pre-operation,3 months after surgery, 1 year after surgery This index was measured by MRI, which means the minimum sagittal diameter of the cervical pulp in the most compressed segment divided by maximum transverse diameter
transverse area change pre-operation,3 months after surgery, 1 year after surgery This index was measured by MRI, which means the cross-sectional area of the cervical pulp at the highest level of compression.
Maximum spinal cord compression change pre-operation,3 months after surgery, 1 year after surgery This index was measured by MRI, which was the ratio of the diameter of the cervical pulp at the most compressed segment to the mean diameter of the cervical pulp at the upper and lower segments without compression
Sagittal Canal Diameter change pre-operation,3 months after surgery, 1 year after surgery This index was measured by CT, which was sagittal diameter of the spinal canal at the most compressed level.
