VisAR Augmented Reality Surgical Guidance System Using Low-Cost Out-of-the-Box HoloLens 2 Hardware Achieves Remarkable Results in Spine Surgery

SALT LAKE CITY, July 15, 2022 /PRNewswire/ — Novarad™ has announced the publication of the article Augmented Reality Spine Surgery Navigation: Increasing Pedicle Screw Insertion Accuracy for Open and Minimally Invasive Spine Surgeries written by participating surgeons from University of Utah, Georgetown University and University of Washington in the June 2022 problem of SPINE (volume 47, number 12). The paper presents precision data for open, minimally invasive pedicle screw navigation achieved by its next-generation augmented reality (AR) surgical guidance technology, VisAR.

VisAR recently received 510(k) clearance from the FDA. The VisAR system translates the patient’s X-ray imaging data into a 3D hologram that is precisely superimposed on the patient by aligning the hologram optical code on the patient. The system is a ready-to-use HoloLens 2 (Microsoft) AR visor, which uses transformation software developed by Novarad for precision-guided open and minimally invasive spine surgery (MISS).

According to dr. Wendell GibbyNovarad CEO, “VisAR technology holds great promise for improving patient care by reducing operating room (OR) times, decreasing radiation for the patient and operating room staff, improving surgical precision and dramatically democratizing access due to much lower cost than traditional navigation and robotic surgical approaches.

Imaging data is retrieved via an encrypted QR code, uploaded wirelessly to the headset, which then allows surgeons to follow a virtual path for precise navigation. Use of workflow automation. OR installation time and registration occurs in less than 2 minutes. Of 124 pedicle screws, ranging from T6 to L5, sixty-five of the screws were placed during open dissection and the remaining fifty-nine were inserted percutaneously. The combined precision, open and MISS, was 96% (Gertzbein-Robbins scale). There was no statistical difference in the distributions of the two surgical methods. In addition, the average angle error was 2.4° (SD 1.2°) and the average distance error was 1.9 mm (SD 0.9 mm). Fluoroscopy was not used during these procedures, minimizing radiation exposure for the patient, surgeon, and operating room personnel. VisAR responds to voice commands for smooth operational control and to maintain OR sterility, with a nominal OR footprint.

  • The VisAR Surgical Navigation System is an advanced and rapidly evolving surgical tool
  • Accurate and precise guidance of open, minimally invasive pedicle screws can be achieved with ready-to-use, inexpensive hardware
