The Surgivisio system offers accurate pedicle screw placement in minimally invasive spine surgery. This intraoperative 3D imaging tool demonstrates effectiveness with acceptable operative times and radiation exposure.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Medical Imaging Technology
Background:
- Minimally invasive spine surgery (MISS) requires precise instrumentation.
- Intraoperative imaging is crucial for accurate pedicle screw placement in MISS.
- The Surgivisio system represents a new generation of intraoperative 3D imaging.
Purpose of the Study:
- To describe the Surgivisio system, its advantages, and limitations.
- To evaluate the accuracy, operative time, and radiation exposure of the Surgivisio system in percutaneous spinal surgery.
Main Methods:
- Analysis of the first year of Surgivisio system use (29 patients).
- Evaluation of pedicle screw insertion accuracy using Heary and Gertzbein classifications.
- Measurement of operative time and radiation exposure per navigated vertebra.
Main Results:
- 95.5% of pedicle screw placements were rated as acceptable (107/112).
- Mean operative time was 29.3 minutes per vertebra.
- Mean radiation exposure was 0.61 mSv per vertebra.
Conclusions:
- The Surgivisio system is an effective navigation tool for pedicle screw insertion in MISS.
- The system provides acceptable radiation exposure and operative time.
- This technology enhances precision in percutaneous spinal procedures.
