Abstract

BACKGROUND CONTEXT: The field of artificial intelligence (AI) is rapidly advancing, especially with recent improvements in deep learning (DL) techniques. Augmented (AR) and virtual reality (VR) are finding their place in healthcare, and spine surgery is no exception. The unique capabilities and advantages of AR and VR devices include their low cost, flexible integration with other technologies, user-friendly features and their application in navigation systems, which makes them beneficial across different aspects of spine surgery. Despite the use of AR for pedicle screw placement, targeted cervical foraminotomy, bone biopsy, osteotomy planning, and percutaneous intervention, the current applications of AR and VR in spine surgery remain limited.PURPOSE: The primary goal of this study was to provide the spine surgeons and clinical researchers with the general information about the current applications, future potentials, and accessibility of AR and VR systems in spine surgery.STUDY DESIGN/SETTING: We reviewed titles of more than 250 journal papers from google scholar and PubMed with search words: augmented reality, virtual reality, spine surgery, and orthopaedic, out of which 89 related papers were selected for abstract review. Finally, full text of 67 papers were analyzed and reviewed.METHODS: The papers were divided into four groups: technological papers, applications in surgery, applications in spine education and training, and general application in orthopaedic. A team of two reviewers performed paper reviews and a thorough web search to ensure the most updated state of the art in each of four group is captured in the review.RESULTS: In this review we discuss the current state of the art in AR and VR hardware, their preoperative applications and surgical applications in spine surgery. Finally, we discuss the future potentials of AR and VR and their integration with AI, robotic surgery, gaming, and wearables.CONCLUSIONS: AR and VR are promising technologies that will soon become part of standard of care in spine surgery.

Abstract

In recent years, a new variant of the GTAW process, commercially named TopTIG, has attracted interest in the industrial sector due to the possibility of increasing productivity and facilitating automated operation. In this technology, the main component is a special welding torch that allows the insertion of a wire tangentially, in a region closer to the tungsten electrode when compared to traditional torches in the GTAW process. In addition, the wire guide is incorporated into the nozzle, making the torch more compact, facilitating operation using an anthropomorphic robot. In a context where automation is desirable to increase productivity even in the most complex manufacturing processes, the use of this new variant as an alternative to facilitate the development of pipeline orbital welding procedures was investigated. The research was conducted to develop procedures for the root and fill passes using 304L stainless steel tubes, with a diameter of 305 mm and thickness of 12.7 mm. In the root pass welding the Keyhole technique of welding was used. The results showed that this technology allows an increase in welding speed and melt rate of wire up to twice in the welding of the root pass compared to other studies found in the literature which use GTAW techniques with larger insertion angles. Therefore, wire feed speeds of approximately 4 m min−1 and welding speeds of up to 0.5 m min−1 were used. The study highlighted the challenges inherent to the robotic application of the GTAW process for orbital welding, especially in relation to the root pass. However, for the envisaged field application of the technology, further robustness oriented welding procedure development must be undertaken, since the process is still sensitive to geometric variations typically found in joint connecting pipes. • Robotic orbital welding with GTAW is possible through a thorough study of welding parameters. • The welding of the root pass with the robotic GTAW process is extremely sensitive to geometric variations of the joint. • Welding of the root pass is possible without changing parameters after obtaining a robust parameterization.
