Background: Computer-assisted solutions are changing surgical practice continuously. One of the most disruptive technologies among the computer-integrated surgical techniques is Augmented Reality (AR). While Augmented Reality is increasingly used in several medical specialties, its potential benefit in orthopedic surgery is not yet clear. The purpose of this article is to provide a systematic review of the current state of knowledge and the applicability of AR in orthopedic surgery. Methods: A systematic review of the current literature was performed to find the state of knowledge and applicability of AR in Orthopedic surgery. A systematic search of the following three databases was performed: "PubMed", "Cochrane Library" and "Web of Science". The systematic review followed the Preferred Reporting Items on Systematic Reviews and Meta-analysis (PRISMA) guidelines and it has been published and registered in the international prospective register of systematic reviews (PROSPERO). Results: 31 studies and reports are included and classified into the following categories: Instrument / Implant Placement, Osteotomies, Tumor Surgery, Trauma, and Surgical Training and Education. Quality assessment could be performed in 18 studies. Among the clinical studies, there were six case series with an average score of 90% and one case report, which scored 81% according to the Joanna Briggs Institute Critical Appraisal Checklist (JBI CAC). The 11 cadaveric studies scored 81% according to the QUACS scale (Quality Appraisal for Cadaveric Studies). Conclusion: This manuscript provides 1) a summary of the current state of knowledge and research of Augmented Reality in orthopedic surgery presented in the literature, and 2) a discussion by the authors presenting the key remarks required for seamless integration of Augmented Reality in the future surgical practice. Trial registration: PROSPERO registration number: CRD42019128569.

“…Implementing Virtual and Augmented Reality Tools for Radiology Education and Training, Communication, and Clinical Care 571 AR-specific applications have shown promise across a number of disciplines (16,17), with emerging potential applications in medical imaging (Fig 2) (18,19). Recent advances in technology have allowed the increased portability of AR hardware, making more widespread utilization possible (19,20) The main types of AR devices include see-through head-mounted displays, mobile-based devices, and projection-based devices (21).…”

dvances in computing technology have enabled widespread availability of simulated reality technologies, including virtual reality (VR) and augmented reality (AR). A number of fields ranging from entertainment and gaming to the military, education, and sports (1-7) have adopted these technologies for use within their respective fields. These technologies provide stereoscopic and three-dimensional (3D) immersion within an environment, as in VR, or overlaid onto a real-world background, as in AR. Many medical specialties are now exploring the application of these tools for their respective fields (8-12). VR and AR technologies are a novel means to communicate and have potential for supplementing radiology training; communicating with colleagues, referring clinicians, and patients; and aiding in interventional radiology procedures. The purpose of this review article is to summarize how three imaging departments have explored VR and AR for radiology. First, we define VR and AR. Second, we detail its application for education and training, communication, and clinical care in interventional radiology. Finally, we review the current limitations and future directions for this technology for radiology.

“…Previous studies showed the validity of the one‐time calibration of an optical camera on the C‐arm . However, due to mechanical sagging of the C‐arm, the stereo extrinsic parameters between the RGBD device and the x‐ray source are subject to small changes when the C‐arm rotates to different angles …”

Purpose Cone-Beam Computed Tomography (CBCT) is one of the primary imaging modalities in radiation therapy, dentistry, and orthopedic interventions. While CBCT provides crucial intraoperative information, it is bounded by a limited imaging volume, resulting in reduced effectiveness. This paper introduces an approach allowing real-time intraoperative stitching of overlapping and non-overlapping CBCT volumes to enable 3D measurements on large anatomical structures. Methods A CBCT-capable mobile C-arm is augmented with a Red-Green-Blue-Depth (RGBD) camera. An off-line co-calibration of the two imaging modalities results in co-registered video, infrared, and X-ray views of the surgical scene. Then, automatic stitching of multiple small, non-overlapping CBCT volumes is possible by recovering the relative motion of the C-arm with respect to the patient based on the camera observations. We propose three methods to recover the relative pose: RGB-based tracking of visual markers that are placed near the surgical site, RGBD-based simultaneous localization and mapping (SLAM) of the surgical scene which incorporates both color and depth information for pose estimation, and surface tracking of the patient using only depth data provided by the RGBD sensor. Results On an animal cadaver, we show stitching errors as low as 0.33 mm, 0.91 mm, and 1.72mm when the visual marker, RGBD SLAM, and surface data are used for tracking, respectively. Conclusions The proposed method overcomes one of the major limitations of CBCT C-arm systems by integrating vision-based tracking and expanding the imaging volume without any intraoperative use of calibration grids or external tracking systems. We believe this solution to be most appropriate for 3D intraoperative verification of several orthopedic procedures.
