Conditions
Brief summary
Prospective comparative study of Mixed Reality Technology（MR）assisted lumbar pedicle screws placement and traditional lumbar pedicle screws placement.
Detailed description
In this study, the randomized controlled method was adopted to prospectively include the samples, and the differences in surgical procedures and efficacy were compared between the thoracolumbar pedicle screw implantation assisted by MR and the traditional thoracolumbar pedicle screw implantation, so as to provide a plan for clinicians to choose the surgical method.

Exclusion criteria
* 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
