Summary
A new "stereo-guide" system simplifies computed tomography (CT)-guided vertebroplasty. This accurate and complication-free device enhances CT-guided procedures for spinal pathologies.
Area of Science:
- Medical Devices
- Minimally Invasive Surgery
- Radiology
Background:
- Computed tomography (CT)-guided vertebroplasty can be complex.
- A novel stereotactic guidance system, the "stereo-guide," was developed to simplify this procedure.
Purpose of the Study:
- To describe a method for performing CT-guided vertebroplasty using the stereo-guide.
- To evaluate the usability and accuracy of the stereo-guide system.
Main Methods:
- The stereo-guide is a plastic block with protractor markings for angle and distance measurements.
- The device is positioned on the patient, and the needle is guided through pedicles using the device's grooves.
- Ten procedures were performed on nine patients with lumbar and thoracic pathology.
Main Results:
- The stereo-guide system was found to be easy to use.
- The system demonstrated accuracy in guiding the procedure.
- No complications were reported during or after the procedures.
Conclusions:
- The stereo-guide is a simple and user-friendly tool for CT-guided vertebroplasty.
- Intraoperative imaging facilitated trajectory planning and cement injection monitoring.
