A novel tricortical screw technique for anterior cervical fixation offers enhanced stability. This method provides firm plate fixation and independently stabilizes adjacent vertebral bodies, reducing the need for additional hardware.

Area of Science:

  • Orthopedic Surgery
  • Spinal Fusion Techniques
  • Biomechanical Engineering

Background:

  • Anterior cervical fixation is crucial for spinal stability.
  • Current methods may have limitations in achieving robust fixation and vertebral body stabilization.

Purpose of the Study:

  • To describe a new tricortical screw implantation method for anterior cervical interbody plate fixation.
  • To evaluate the efficacy of this technique in stabilizing cervical spine segments.

Main Methods:

  • A novel tricortical screw placement technique is detailed, engaging anterior and adjacent cortices.
  • Oblique screw trajectory ensures engagement of multiple cortical layers.
  • The method was applied to sixteen patients, with three receiving screws alone without a plate.

Main Results:

  • The tricortical screw purchase provides firm plate fixation.
  • The screw's trajectory inherently stabilizes adjacent vertebral bodies.
  • Successful application in sixteen patients demonstrates feasibility.

Conclusions:

  • The described tricortical screw method enhances anterior cervical fixation stability.
  • This technique offers potential advantages in simplifying fixation and improving biomechanical support.
  • Further investigation into its long-term efficacy and broader applications is warranted.
