Summary
Navigated Percutaneous Lumbosacral Interbody Fusion (NPLSIF) is a novel surgical technique that allows for safe and effective percutaneous discectomy and bone grafting. Anatomical simulations confirm the feasibility of NPLSIF for lumbosacral fusion procedures.
Area of Science:
- Spinal Surgery
- Minimally Invasive Procedures
- Surgical Navigation
Background:
- Surgical navigation advancements enable new possibilities for lumbosacral interbody fusion.
- A novel navigated surgical method, Navigated Percutaneous Lumbosacral Interbody Fusion (NPLSIF), has been developed.
- NPLSIF facilitates percutaneous and safe lumbosacral discectomy and bone grafting.
Purpose of the Study:
- To evaluate the anatomical feasibility of the NPLSIF technique.
- To assess the potential for achieving adequate discectomy using NPLSIF.
- To validate the safety and precision of the NPLSIF approach through simulation.
Main Methods:
- Anatomical feasibility was assessed using 3D models from CT data of 60 patients.
- Simulations verified the accommodation of the working corridor and S1 pedicle screw within the sacral ala.
- Discectomy achievement and a torso model experiment evaluated the NPLSIF procedure.
Main Results:
- NPLSIF simulations were successful in all cases, confirming anatomical feasibility.
- The working corridor and S1 pedicle screw fit within the sacral ala without critical penetration.
- Mean discectomy ratios ranged from 0.721 to 0.956 across planes; simulations showed no canal or sacral wall penetration.
Conclusions:
- The anatomical feasibility of Navigated Percutaneous Lumbosacral Interbody Fusion (NPLSIF) is confirmed.
- The NPLSIF procedure allows for adequate discectomy in lumbosacral fusion.
- Further cadaveric and clinical studies are required to ascertain NPLSIF's efficacy and efficiency.
