Outcome Measures

Primary Outcomes (3)

  • Visual Analog Scale

    visual analog scale(0-10 scores) is for pain, 0 represent no pain, 10 score represent the severe pain.

    6 months

  • Oswestry Disability Index

    Oswestry Disability Index is for movement function, Questionnaire examines

    6 months

  • The Standard Of Gertzbein-Robbins

    the standard of Gertzbein-Robbins :Ⅰ, self-contained complete within the pedicle nail; Ⅱ, self-contained nail through 2 mm below the cortex; Ⅲ, self-contained nail through 2 mm or greater, cortex \< 4 mm; Nail through 4 mm or higher cortex; Ⅳ, self-contained, \< 6 mm; Ⅴ, self-contained nail through 6 mm or higher cortex.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Course of disease≥6 months, all patients with lumbago back pain, radiation pain of lower limbs, lumbar disc herniation diagnosed with or without spinal stenosis.
  • The course of disease≥6 months, all patients had lumbar back pain, accompanied by or without intermittent claudication, and the diagnosis of lumbar spondylolisthesis was clear, but the vertebral isthmus was not broken.
  • The patient's symptoms were consistent with the imaging examination results, failed to respond to conservative treatment, and met the surgical indications.
  • The lesion segment is no more than 3 vertebral bodies.
  • Preoperative improvement of X-ray, CT, MRI examination.
  • Patients without active bleeding and female patients is not in menstrual period.

You may not qualify if:

  • Lumbar acute infection, lumbar tuberculosis, tumor and other diseases.
  • Patients with severe cardiopulmonary insufficiency, intolerance to surgery, diabetes and poor blood glucose control, combined with coagulation dysfunction and other contraindications.
  • Vertebral fracture patients.
  • Bone Mineral Density (BMD) examination: BMD was measured by dual-energy X- ray absorptiometry at the lumbar spine (L2 \~ L4) and femoral head, and BMD and T values were observed. Abnormal bone mass were excluded according T \>- 1 SD
