Summary
Brief summary (as posted)
Finite element method was used to simulate unilateral hemilaminectomy of cervical spine and facet joint resection of different degrees, and the range of motion and the stress changes of ligament, intervertebral disc and endplate were calculated immediately after operation

- Through study completion, an average of 1 year
- description
- In this study, the pure torque of 2.0Nm was applied to the upper surface of C2 vertebral body along the 1, 2 and 3 coordinates according to the right hand helical rule to generate the corresponding pure torque in the sagittal plane, coronal plane and axial plane, and to simulate the cervical spine flexion and extension, lateral bending and left-right rotation in real life
