A new, affordable software for computer-assisted pedicle screw placement was developed. Cadaveric studies show it is accurate and superior to traditional methods, especially for thoracic spine surgery.

Area of Science:

  • Spinal Surgery
  • Medical Device Development
  • Surgical Navigation

Background:

  • Computer-assisted pedicle screw placement systems are highly accurate but prohibitively expensive.
  • High accuracy is essential for current spinal surgeries, particularly pedicle screw insertion.

Purpose of the Study:

  • To develop a novel, cost-effective software for computer-assisted pedicle screw placement.
  • To evaluate the accuracy and educational value of the new software.

Main Methods:

  • Development of new software utilizing paired point matching for pedicle screw placement.
  • Validation of software accuracy through a cadaveric study.

Main Results:

  • The developed software is significantly less expensive than existing systems.
