Summary
Minimally invasive spinal surgery using percutaneous pedicle screws offers benefits like shorter hospital stays. This review provides guidelines for safe screw implantation, addressing technical challenges for surgeons.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Background:
- Minimally invasive spinal surgery (MISS) is gaining traction due to advantages such as reduced hospital stay, blood loss, and pain management needs.
- The expansion of indications for percutaneous pedicle screw techniques necessitates a deeper understanding of their nuances.
Purpose of the Study:
- To provide guidelines for the safe implantation of percutaneous pedicle screws using image intensification.
- To share collective knowledge from experienced surgeons to aid those new to these complex procedures.
Main Methods:
- Review of current literature and surgical techniques for percutaneous pedicle screw placement.
- Discussion of technical challenges encountered during minimally invasive spinal fusion.
Main Results:
- Guidelines for safe percutaneous pedicle screw implantation are presented.
- Common technical challenges are identified, including pedicle cannulation, rod insertion, incision planning, screw trajectory adjustments, and managing difficult pedicle anatomy.
Conclusions:
- Percutaneous pedicle screw techniques are valuable for complex spinal surgery.
- Sharing expertise is crucial for the safe and effective adoption of these advanced minimally invasive procedures.
