Lateral Mass Fixation in the Subaxial Cervical Spine

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Spinal Fusion Techniques

Background:

• Posterior cervical spine fusions frequently utilize lateral mass screws and rods.
• Established techniques like Magerl, Anderson, and An aim for secure fixation.
• Protecting neurovascular structures is paramount during screw placement.

Purpose of the Study:

• To review the standard fixation methods for posterior cervical spine fusions.
• To highlight the safety and efficacy of lateral mass screw usage.

Main Methods:

• Review of established surgical techniques for lateral mass screw placement in the subaxial cervical spine.
• Analysis of goals for achieving solid bony fixation and neurovascular safety.

Main Results:

• Lateral mass screw and rod fixation is the standard for posterior cervical fusions.
• Multiple techniques exist, all prioritizing bony fixation and neurovascular protection.
• The use of lateral mass screws is a safe and effective method.

Conclusions:

• Lateral mass screw fixation is a well-established and reliable technique for posterior cervical spine fusion.
• The described methods provide a balance between achieving solid fusion and minimizing risks to neurovascular structures.
