Outcome Measures

Primary Outcomes (4)

  • lamina open angle

    The Angle of opening of the cervical unilateral lamina while cervical single open-door surgery

    3 months after surgery

  • 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%.

    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.

    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.

    pre-operation,3 months after surgery

Secondary Outcomes (4)

  • Maximum spinal cord compression change

    pre-operation,3 months after surgery, 1 year after surgery

  • 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

  • Sagittal Canal Diameter change

Eligibility Criteria

Age18 Years - 86 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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.
