Summary
Mixed reality (MR) provides accurate navigation for thoracic spine surgery. This study demonstrated MR
Area of Science:
- Neurosurgery
- Medical Technology
- Surgical Navigation
Background:
- Mixed reality (MR) offers potential for enhancing surgical navigation in spine procedures.
- Key factors for MR adoption include workflow, stability, reliability, and accuracy.
- Investigating MR accuracy in visualizing thoracic spine anatomy is crucial for its clinical application.
Purpose of the Study:
- To evaluate the accuracy of mixed reality (MR) for visualizing thoracic spine pedicles.
- To assess the precision of MR-based anatomical structure overlay in a cadaveric model.
Main Methods:
- Computed tomography (CT) scans of a human cadaveric spine were acquired.
- HoloLens 2 software was used for segmentation and 3D model creation.
- Accuracy was measured by comparing virtual pedicle holographs to exposed anatomical structures.
Main Results:
- The overlay of virtual 3D pedicle models onto real anatomy achieved acceptable surgical accuracy (mean deviation: 2.1 mm).
- Highest accuracy was observed at the medial and lateral pedicle walls.
- The middle thoracic spine region demonstrated the best measurement results.
Conclusions:
- Mixed reality (MR) shows high accuracy for thoracic spine pedicle visualization, confirming its precision for surgical areas.
- The findings support the development and application of MR technology in spinal navigation.
- This study provides evidence for the potential of MR in improving surgical outcomes.
