Abstract:

BACKGROUND: Cervical pedicle screw internal fixation has a high risk for the treatment of cervical spine instability. Research and analysis on the fixation effect of cervical pedicle screw placement for the treatment of cervical spine instability should be performed in order to determine the feasibility and reliability of cervical pedicle screw placement for the treatment of cervical spine instability.
OBJECTIVE: To in-depth analyze the fixation effect of cervical pedicle screw placement for the treatment of cervical spine instability, and to provide the important data and reference information for the treatment of cervical spine instability.
METHODS: The biomechanics, morphology and clinical follow-up test of the instable cervical spine were analyzed after cervical pedicle screw placement, and the fixation effect of cervical pedicle screw placement for the treatment of cervical spine instability was analyzed. We have analyzed from different aspects in order to determine the feasibility and safety of cervical pedicle screw system in treating the cervical spine instability.
RESULTS AND CONCLUSION: The cervical pedicle screw placement has a satisfactory therapeutic effect in the treatment of cervical spine instability no matter from the biomechanical and morphological aspects, or from the aspect of clinical applications. The cervical pedicle screw placement is one of the reliable and safe treatment methods for cervical spine instability as it has an important significance in improving the patient's clinical symptoms and relieving the pain.
