Area of Science:

  • Orthopedic Surgery
  • Medical Technology
  • Spine Surgery

Background:

  • Mixed Reality (MR) is increasingly utilized in orthopedic surgery.
  • Limited research exists on MR applications for Lumbar Fractures (LF).

Purpose of the Study:

  • To investigate the feasibility and safety of using an MR-based navigation system for Lumbar Fracture treatment.
  • To evaluate the precision of pedicle screw implantation assisted by MR technology.

Main Methods:

  • Retrospective analysis of 7 patients undergoing posterior vertebrectomy for Lumbar Fractures.
  • Utilized an MR-based intraoperative three-dimensional image-guided navigation system (MITINS) for pedicle screw placement.
  • Assessed screw accuracy via postsurgery radiography and patient outcomes using VAS and ODI scores.

Main Results:

  • Successfully and precisely implanted 57 pedicle screws using MITINS in 7 patients.
  • No screws were misplaced outside the pedicle.
  • MITINS eliminated the need for intraoperative X-ray guidance for screw placement.

Conclusions:

  • The MR-based intraoperative three-dimensional image-guided navigation system (MITINS) is a feasible, safe, and accurate tool for Lumbar Fracture surgery.
  • MITINS provides significant assistance to spine surgeons, enhancing pedicle screw implantation.
  • This technology offers satisfactory outcomes in treating Lumbar Fractures.
