Intraoperative 3-dimensional navigation (ION) enhances minimally invasive spine surgery like LLIF and OLIF by improving accuracy and efficiency. While ION offers benefits, patient radiation exposure remains a controversial topic requiring further research.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Medical Technology

Background:

  • Minimally invasive spine surgery (MISS) techniques, including lateral lumbar interbody fusion (LLIF) and oblique lumbar interbody fusion (OLIF), are increasingly popular.
  • These lateral approaches preserve spinal elements but traditionally rely on fluoroscopy for instrument and implant placement.
  • Intraoperative 3-dimensional navigation (ION) has emerged as a significant innovation in MISS.

Purpose of the Study:

  • To review the role and impact of intraoperative 3-dimensional navigation (ION) in lateral position spine surgery.
  • To discuss the potential benefits of ION, including improved accuracy, reduced operating times, and decreased radiation exposure for surgical staff.
  • To address the ongoing controversy regarding intraoperative radiation exposure to patients during ION-assisted procedures.

Main Methods:

  • Review of recent advances and applications of intraoperative 3-dimensional navigation (ION) in lateral lumbar interbody fusion (LLIF) and oblique lumbar interbody fusion (OLIF).
  • Discussion of ION technology utilizing intraoperative advanced imaging (e.g., CT) for real-time 3D anatomical mapping and instrument visualization.
  • Exploration of the potential for single-position surgery facilitated by ION.

Main Results:

  • ION offers potential improvements in surgical accuracy and efficiency for LLIF and OLIF procedures.
  • ION may decrease operating room times and reduce radiation exposure for surgeons and staff.
  • The feasibility of single-position surgery, combining lateral and posterior instrumentation, is enhanced with ION.

Conclusions:

  • Intraoperative 3-dimensional navigation (ION) represents a significant technological advancement in lateral minimally invasive spine surgery.
  • Despite its advantages, the radiation risk to patients during ION-assisted surgery requires further investigation and remains a point of debate.
  • Future research should focus on ultra-low radiation imaging techniques, image enhancement, and robotic-assisted navigation for single-position spine surgery.
