Augmented Reality in Spine Surgery Narrative Review: Seeing is Believing

In recent years, augmented reality (AR) has emerged as a promising technology in spine surgery. Its benefits are numerous, including enhanced surgical accuracy, improved anatomic approximation, and uninterrupted visualization. It has proven particularly valuable in spinal fusion, allowing for meticulous planning of screw trajectories and precise alignment of screws, plates, and implants, resulting in low complication rates. Additionally, AR reduces radiation exposure by minimizing the need for intraoperative fluoroscopy. The technology has also been utilized for surgical education and training, enabling real-time feedback through telementoring. However, challenges exist. Discomfort and wearability issues are reported with current AR models, and the need for 3D image rendering prolongs procedure time. Accuracy is compromised in patients with larger body habitus, necessitating improvements in calibration to individual anatomies. Cost is another significant challenge as it requires advanced imaging capabilities in operating rooms, along with expenses for AR hardware, software, training, and personnel. Ongoing research is necessary to evaluate the sustained benefits and potential complications of AR in spine surgery. While AR demonstrates advantages in terms of patient outcomes and surgical accuracy, continued optimization is essential to enhance accessibility and success in spine surgery and orthopaedic surgery as a whole.
