Summary
Cervical pedicle screws (CPS) offer superior biomechanical stabilization for unstable cervical spine trauma. This review details CPS indications, techniques, and complication prevention for effective trauma management.
Area of Science:
- Orthopedics
- Neurosurgery
- Spinal Surgery
Background:
- Unstable cervical traumatic lesions require effective stabilization.
- Cervical pedicle screws (CPS) demonstrate biomechanical superiority in such cases.
Purpose of the Study:
- To review and summarize indications for CPS use in cervical trauma.
- To outline technical guidelines for CPS insertion.
- To discuss potential neurovascular complications and their prevention.
Main Methods:
- Review of literature on cervical pedicle screw application in trauma.
- Analysis of indications, surgical techniques, and complication data.
- Emphasis on preoperative anatomical evaluation and procedural steps.
Main Results:
- CPS are reliable for stabilizing fractured lamina, lateral mass, and three-column injuries.
- Techniques include fluoroscopy-guided, image-guided navigation, 3D template-guided, and freehand methods.
- Potential complications include vertebral artery, spinal cord, and nerve root injury due to misplacement.
Conclusions:
- Cervical pedicle screw fixation is effective for unstable cervical trauma.
- Various insertion techniques offer advantages in accuracy and applicability.
- Meticulous preoperative planning and adherence to procedural guidelines are crucial for preventing neurovascular complications.
