Intraoperative spinal navigation improves pedicle screw accuracy but has potential pitfalls. This article details common issues and provides practical tips for avoidance and management in spinal fixation procedures.

Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Spinal Instrumentation

Background:

  • Transpedicular constructs and pedicle screws are standard in spinal fixation for rigid posterior stabilization.
  • Conventional pedicle screw placement using landmarks and fluoroscopy has documented inaccuracies (10-50%).
  • Image-guided navigation systems enhance accuracy and safety, particularly in complex spinal deformities.

Purpose of the Study:

  • To summarize the authors' experience with potential pitfalls of intraoperative spinal navigation.
  • To provide practical guidance on avoiding and managing these navigation-related complications.

Main Methods:

  • Review of over 1500 cases utilizing image-guided spinal navigation.
  • Analysis of identified pitfalls encountered during pedicle screw placement with navigation.

Main Results:

  • Intraoperative spinal navigation offers improved accuracy but presents unique challenges.
  • Several potential pitfalls associated with image guidance can lead to suboptimal outcomes.

Conclusions:

  • While spinal navigation enhances pedicle screw placement, awareness of its pitfalls is crucial.
  • Practical strategies for avoiding and managing these issues are essential for optimizing surgical results.
