Summary
Minimally invasive posterior cervical fixation uses advanced screw systems for subaxial cervical spine fusion. These systems offer versatile screw angulation, simplifying complex spinal surgeries.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Background:
- Subaxial cervical spine injuries require stable fixation.
- Traditional posterior approaches can be invasive.
- Advancements in internal fixation systems are crucial for surgical outcomes.
Purpose of the Study:
- To describe the application of minimally invasive posterior cervical arthrodesis.
- To highlight the benefits of advanced screw-rod interface systems.
- To evaluate the feasibility of minimally invasive posterior cervical fixation.
Main Methods:
- Utilizing polyaxial tulip or islet connectors for screw fixation.
- Employing systems with variable screw angulation (medial, lateral, straight).
- Implementing top-loading surgical approaches for easier segmental fixation.
Main Results:
- Achieved segmental fixation with greater ease via a top-loading approach.
- Demonstrated the adaptability of polyaxial screws in posterior cervical fixation.
- Enabled the possibility of minimally invasive posterior cervical fusion.
Conclusions:
- Minimally invasive posterior cervical arthrodesis is feasible with advanced fixation systems.
- Polyaxial screw technology enhances surgical flexibility in the cervical spine.
- These techniques offer a less invasive option for subaxial cervical spine stabilization.
