Investigators
Eligibility Criteria
Inclusion Criteria
- •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
Exclusion Criteria
- •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.
Outcomes
Primary Outcomes
NDI score change
Time Frame: 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
Time Frame: 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.
lamina open angle
Time Frame: 3 months after surgery
The Angle of opening of the cervical unilateral lamina while cervical single open-door surgery
JOA score change
Time Frame: 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 Outcomes
- Compression ratio change(pre-operation,3 months after surgery, 1 year after surgery)
- transverse area change(pre-operation,3 months after surgery, 1 year after surgery)
- Maximum spinal cord compression change(pre-operation,3 months after surgery, 1 year after surgery)
- Sagittal Canal Diameter change(pre-operation,3 months after surgery, 1 year after surgery)
