“…AR systems for intraoperative guidance during spine surgeries have tremendously improved. Previous studies have demonstrated the unique advantages of ARbased image guidance systems [ 3 , 11 , 12 ]. However, current intraoperative navigation and AR systems have notable limitations such as size, cost, and requirement of intraoperative scanning (i.e., intraoperative CT, magnetic resonance imaging [MRI], and/or fluoroscopy) for registration.…”

A phantom model was used to evaluate the accuracy of a novel augmented reality (AR) system for cervical screw placement. Overview of Literature: The use of navigation systems is becoming increasingly common in spine procedures. However, numerous factors limit the feasibility of regular and widespread use of navigation tools during spine surgery. AR is a new technology that has already demonstrated utility as a navigation tool during spine surgery. However, advancements in AR technology are needed to increase its adoption by the medical community. Methods: AR technology that uses a fiducial-less registration system was tested in a preclinical cervical spine phantom model study for accuracy during spinal screw placement. A three-dimensional reconstruction of the spine along with trajectory lines was superimposed onto the phantom model using an AR headset. Participants used the AR system to guide screw placement, and post-instrumentation scans were compared for accuracy assessment. Results: Twelve cervical screws were placed under AR guidance. All screws were placed in an acceptable anatomic position. The average distance error for the insertion point was 2.73±0.55 mm, whereas that for the endpoint was 2.71±0.69 mm. The average trajectory angle error for all insertions was 2.69°±0.59°. Conclusions: This feasibility study describes a novel registration approach that superimposes spinal anatomy and trajectories onto the surgeon's real-world view of the spine. These results demonstrate reasonable accuracy in the preclinical model. The results of this study demonstrate that this technology can assist with accurate screw placement. Further investigation using cadaveric and clinical models is warranted.

“… 35 , 36 Computer-assisted navigation systems are based on two-dimensional or three-dimensional images and utilize high-speed computer processing of large amounts of data to provide real-time surgical navigation and simulation capabilities. 37 It provides surgeons with accurate anatomical localization and operative guidance, improving the precision and safety of the surgery, and offering a more minimally invasive approach with better outcomes for patients. CAN has been shown to improve workflow in the operating room and enhance the safety and accuracy of minimally invasive instrumentation compared to manual or fluoroscopy-guided screw placement.…”

Purpose Adult degenerative scoliosis (ADS) research lacks bibliometric analysis, despite numerous studies. This study aimed to systematically analyze the development, current status, hot topics, frontier areas, and trends in ADS research. Patients and Methods A systematic literature review was conducted in the Web of Science Core Collection database from January 1998 to June 2023. Information regarding the country, institution, author, journal, and keywords was collected for each article. Bibliometric analysis was performed using VOSviewer and Citespace software. Results The final analysis covered 1695 publications, demonstrating a steady increase in ADS research. The United States was the most prolific and influential country with 684 publications, followed by China and Japan. The University of California System was the most productive institution with 113 publications. Shaffrey, CI (47 publications) and Lenke, LG (41 publications) were top authors. The analysis revealed seven main research clusters: “intervertebral disc”, “adult spinal deformity”, “lumbar fusion”, “minimally invasive surgery”, “navigation”, “postoperative complications”, and “mental retardation”. Keywords with strong bursts of activity included degeneration, prevalence, imbalance, classification, lumbar spinal stenosis, and kyphosis. Conclusion In conclusion, in recent years, ADS research has undergone rapid development. This study analyzed its hot topics, advancements, and research directions, making it the latest bibliometric analysis in this field. The findings aim to provide a new perspective and guidance for clinical practitioners and researchers.

“…Recently, various instrument tracking systems have been reported, including navigation [27,28], robotics [28][29][30][31], and augmented reality [27,31,32], for pedicle screw insertion in spine surgeries. These instrument tracking systems could improve the accuracy of pedicle screw placement [29,30].…”

Background: In recent years, intraoperative computed tomography (CT) navigation has become widely used for the insertion of pedicle screws in spinal fusion surgery. However, conventional intraoperative CT navigation may be impaired by infrared interference between the infrared camera and surgical instruments, which can lead to the misplacement of pedicle screws. Recently, a novel intraoperative CT navigation system, NextAR, has been developed. It uses a small infrared camera mounted on surgical instruments within the surgical field. NextAR navigation can minimize the problem of infrared interference and be expected to improve the accuracy of pedicle screw placement. Methods: This study investigated the accuracy of pedicle screw insertion under NextAR navigation in spinal fusion surgery for lumbar degenerative diseases. The accuracy of pedicle screw placement was evaluated in 15 consecutive patients using a CT grading scale. Results: Screw perforation occurred in only 1 of the total 70 screws (1.4%). Specifically, there was one grade 1 perforation within 2 mm, but no perforations larger than 2 mm. There were no reoperations or neurological complications due to screw misplacement. Conclusions: NextAR navigation can provide high accuracy for pedicle screw insertion and help ensure safe spinal fusion surgery for lumbar degenerative diseases.
