Augmented Reality in Spine Surgery.

Abstract

Augmented reality (AR) is a technology that allows digital information to be superimposed onto a user's view of the real world, thereby enhancing the user's experience of a given real-world scenario. As recent advances in AR technology have made it more available for a variety of applications, hospitals and doctors have begun to test its utility in the operating room. AR technology allows surgeons to supplement their view of the operative field with useful patient-specific information for which they might otherwise need to turn their attention away from the task at hand. For spine surgeons in particular, AR has begun to emerge as a promising option to assist with surgical performance. The field of spine surgery is uniquely positioned to benefit from AR, given the extent to which many spine surgeons already rely on intraoperative navigation techniques for certain surgical tasks, including pedicle screw and interbody device placement. In this review, we outline the origins and history of AR in spine surgery and cover the current state of the literature regarding the applications, benefits, and drawbacks of its use within the field. Lastly, we speculate as to the future of AR in spine surgery and propose which gaps in knowledge must be addressed before the technology enjoys a degree of adoption on par with currently available intraoperative navigation techniques.
