Summary
This review covers posterior fixation methods for the subaxial cervical spine. Lateral mass and pedicle screw fixation offer safe stabilization when anatomical understanding and preoperative evaluation are prioritized.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Posterior fixation techniques are crucial for stabilizing the subaxial cervical spine.
- Common methods include posterior wiring, laminar screw fixation, lateral mass fixation, and pedicle screw fixation.
Purpose of the Study:
- To review the historical context, indications, techniques, and complications of four posterior fixation methods for subaxial cervical spine stabilization.
- To compare the safety and reliability of different posterior fixation techniques.
Main Methods:
- Review of historical and current literature on posterior fixation techniques for the subaxial cervical spine.
- Analysis of anatomical considerations, surgical techniques, and potential complications associated with each method.
Main Results:
- Posterior wiring and laminar screw fixation are rarely used currently.
- Lateral mass and pedicle screw fixation are technically demanding and carry risks of significant complications if not performed correctly.
- Both lateral mass and pedicle screw fixation can be safe and reliable with adequate anatomical knowledge and preoperative planning.
Conclusions:
- A thorough understanding of anatomy and rigorous preoperative evaluation are essential for successful subaxial cervical spine fixation.
- Lateral mass and pedicle screw fixation represent the current standard for posterior subaxial cervical spine stabilization, offering reliable outcomes when executed properly.
