| 520 | _aCONCLUSIONS: Augmented reality is a highly accurate, emerging technology for navigating both open and minimally invasive spine surgery techniques with off-the-shelf headset hardware. Copyright (c) 2022 Wolters Kluwer Health, Inc. All rights reserved. | ||
| 520 | _aMETHODS: Prior to CT a series of 4-5 image visible AprilTag optical fiducials were attached to the backs' of the donors. Resulting images were used pre-operatively for planned virtual pedicle screw pathways including entry point, trajectory, and depth. The study was encrypted on a QR code, printed, and viewed in the OR by the surgeon using VisAR (HoloLens 2 headset). Viewing the code wirelessly uploads and launches the study, converting the DICOM data to holographic images which register to the fiducials on the donor's back. The annotated pathways for each pedicle were called up by voice command and the surgeon positioned each screw by aligning with the virtual guidance hologram. | ||
| 520 | _aOBJECTIVE: The objective of this study was to determine the accuracy of pedicle screw placement using VisAR for open spine and MISS procedures. | ||
| 520 | _aRESULTS: Overall, 124 pedicle screws were inserted with VisAR navigation with 96% accuracy (Gertzbein-Robbins grades A and B). The combined angle of error was 2.4degreeand the distance error was 1.9 mm. | ||
| 520 | _aSTUDY DESIGN: Collectively, seven cadavers were instrumented with 124 thoracolumbar pedicle screws using VisAR augmented reality/guidance. Sixty-five screws were inserted into four donors using open dissection spine surgery. Fifty-nine screws were positioned in 3 donors with a minimally invasive spine surgery (MISS) procedure. For both open and MISS, VisAR was used exclusively for pedicle screw navigation. | ||
| 520 | _aSUMMARY OF BACKGROUND DATA: Pedicle screw placement can be challenging depending on anatomical location and a surgeon's experience. AR may minimize fluoroscopy use and speed screw insertion. | ||
