Image-based drilling guide templates offer improved accuracy for pedicle screw placement in spinal surgery. Optimized template designs can ensure successful screw insertion, even in challenging anatomical regions.

Area of Science:

  • Orthopaedic surgery
  • Medical device engineering

Background:

  • Freehand pedicle screw insertion is associated with risks like perforation and nerve injury.
  • Image-guided navigation systems enhance accuracy but have limitations.

Purpose of the Study:

  • To evaluate the accuracy of image-based drilling guide templates for spinal pedicle screw placement.
  • To assess the dimensional stability of duraform polyamide after autoclaving for template manufacturing.

Main Methods:

  • A cadaveric study involving 4 spines (lumbar, thoracic, cervical) and 50 planned screw placements.
  • Manufacturing of 18 personalized drilling guide templates in four designs.
  • Evaluation of screw placement accuracy by experienced surgeons using CT imaging.

Main Results:

Related Experiment Videos

  • Duraform polyamide demonstrated dimensional stability after sterilization via autoclaving.
  • Two template designs achieved 100% accuracy in screw placement (20/20 screws).
  • Successful screw placement was possible even in small pedicles with optimized templates.

Conclusions:

  • Image-based drilling guide templates can significantly improve pedicle screw placement accuracy.
  • Optimized template design, including rotational stabilization, is crucial for success.
  • These templates offer a viable alternative to freehand techniques and current navigation systems.
