A novel modular reference clamp system for navigated spine surgery was developed and tested in cadavers. This system demonstrated stable fixation and accurate pedicle screw placement, enhancing surgical precision.

Area of Science:

  • Spinal surgery
  • Neurosurgery
  • Orthopedic surgery

Background:

  • Current reference clamp systems for navigated spine surgery were not specifically designed for spinal anatomy.
  • This can lead to insufficient fixation, potentially causing complications.

Purpose of the Study:

  • To develop and evaluate a novel modular reference array fixation system tailored for navigated spine surgery.
  • To assess the system's precision and accuracy in pedicle screw placement.

Main Methods:

  • A modular reference clamp system was designed for spinal applications.
  • The system's efficacy was tested in two formalin-fixed whole-body cadavers.
  • Pedicle screws were implanted in cervical, thoracic, and lumbar spine levels, with 2D and 3D fluoroscopic verification.

Main Results:

  • All pedicle screw placements were performed successfully without technical issues.
  • The reference array clamps maintained stable fixation throughout the procedures.
  • No loosening, displacement, or damage to spinous processes was observed.

Conclusions:

  • Stable reference array fixation is crucial for successful navigated spine surgery.
  • The developed modular clamp system proved effective in a cadaveric model for precise pedicle screw placement.
