JOA score change
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%.
Time frame: pre-operation,3 months after surgery, 1 year after surgery
NDI score change
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.
Time frame: pre-operation,3 months after surgery, 1 year after surgery
VAS score change
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.

Maximum spinal cord compression change
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

Time frame: pre-operation,3 months after surgery, 1 year after surgery
Compression ratio change
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
Time frame: pre-operation,3 months after surgery, 1 year after surgery
transverse area change
This index was measured by MRI, which means the cross-sectional area of the cervical pulp at the highest level of compression.
Time frame: pre-operation,3 months after surgery, 1 year after surgery
Sagittal Canal Diameter change
This index was measured by CT, which was sagittal diameter of the spinal canal at the most compressed level.
Time frame: pre-operation,3 months after surgery, 1 year after surgery
