Summary
This study demonstrates a computed tomography-guided navigation system for spinal fusion surgery. The technique ensures accurate and efficient pedicle screw insertion, enhancing surgical outcomes.
Area of Science:
- Neurosurgery
- Medical Imaging
- Surgical Technology
Background:
- Navigation surgical systems are crucial for accuracy and safety in spinal fusion.
- Pedicle screw insertion is a key step requiring precise guidance.
Purpose of the Study:
- To evaluate the effectiveness of a novel computed tomography (CT)-guided navigation system for spinal fusion.
- To assess the accuracy and efficiency of pedicle screw placement using this navigation technique.
Main Methods:
- The study utilized stereotactic navigation, specialized surgical instruments, and custom software under laboratory conditions.
- Preoperative planning involved patient data and CT imaging for visual guidance.
- Surgical instrument navigation was monitored throughout the pedicle screw insertion process.
Main Results:
- 100% clinical accuracy was achieved in inserting 20 pedicle screws into a lumbar spine phantom (average pedicle width: 12.6 ± 1.29 mm).
- 96.67% efficiency was observed in inserting 30 pedicle screws into sheep vertebrae (average pedicle width: 6.56 ± 0.58 mm).
Conclusions:
- The CT-guided navigation system proved highly effective for guiding surgical instruments.
- This technique significantly enhances pedicle screw navigation during spinal fusion procedures.
