Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Medical Imaging

Background:

  • Minimally invasive spine surgery (MIS) offers reduced postoperative pain and disability.
  • Extensive intraoperative fluoroscopy is often required in MIS due to limited surgical field visualization.
  • Standard fluoroscopy use can lead to increased ionizing radiation exposure for surgical teams.

Purpose of the Study:

  • To evaluate the feasibility and safety of employing navigation-assisted fluoroscopy during minimally invasive spine surgery.
  • To compare radiation exposure and surgical efficiency between navigation-assisted and standard fluoroscopy techniques.

Main Methods:

  • A combined cadaveric and human study comparing navigation-assisted fluoroscopy with standard fluoroscopy for minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).
  • Cadaveric analysis involved comparing surgical times for key steps in MIS TLIF using both techniques.
  • Clinical evaluation included prospective data from patients undergoing navigation-assisted MIS TLIF versus retrospective data from patients undergoing standard fluoroscopy MIS TLIF.

Main Results:

  • No significant differences in surgical times were observed between navigation-assisted and standard fluoroscopy groups in cadaveric studies, except for setup time.
  • Navigation-assisted fluoroscopy resulted in significantly lower total fluoroscopy times and reduced radiation exposure (undetectable vs. 12.4 mREM) compared to standard fluoroscopy.
  • Clinical data showed significantly lower total fluoroscopy time in the navigation-assisted group (57.1s vs. 147.2s) with no increase in complications or adverse outcomes.

Conclusions:

  • Navigation-assisted fluoroscopy is a feasible and safe technique for minimally invasive spine surgery.
  • This technology effectively decreases radiation exposure for both patients and surgical personnel.
  • Navigation-assisted fluoroscopy enhances safety in MIS procedures without negatively impacting surgical outcomes.
