Augmented Reality-Assisted Spine Surgery: An Early Experience Demonstrating Safety and Accuracy with 218 Screws

Study Design Prospective cohort study. Objectives In spine surgery, accurate screw guidance is critical to achieving satisfactory fixation. Augmented reality (AR) is a novel technology to assist in screw placement and has shown promising results in early studies. This study aims to provide our early experience evaluating safety and efficacy with an Food and Drug Administration-approved head-mounted (head-mounted device augmented reality (HMD-AR)) device. Methods Consecutive adult patients undergoing AR-assisted thoracolumbar fusion between October 2020 and August 2021 with 2 -week follow-up were included. Preoperative, intraoperative, and postoperative data were collected to include demographics, complications, revision surgeries, and AR performance. Intraoperative 3D imaging was used to assess screw accuracy using the Gertzbein-Robbins (G-R) grading scale. Results Thirty-two patients (40.6% male) were included with a total of 222 screws executed using HMD-AR. Intraoperatively, 4 (1.8%) were deemed misplaced and revised using AR or freehand. The remaining 218 (98.2%) screws were placed accurately. There were no intraoperative adverse events or complications, and AR was not abandoned in any case. Of the 208 AR-placed screws with 3D imaging confirmation, 97.1% were considered clinically accurate (91.8% Grade A, 5.3% Grade B). There were no early postoperative surgical complications or revision surgeries during the 2 -week follow-up. Conclusions This early experience study reports an overall G-R accuracy of 97.1% across 218 AR-guided screws with no intra or early postoperative complications. This shows that HMD-AR-assisted spine surgery is a safe and accurate tool for pedicle, cortical, and pelvic fixation. Larger studies are needed to continue to support this compelling evolution in spine surgery.

Establishing the Groundwork for Clinical Trials With Hiccupops® for Hiccup Palliation

Objective Because hiccup palliation remains an unmet clinical need, we report here on an early experience with Hiccupops, ® a patented product designed for the express purpose of providing a mechanism-based intervention for hiccup palliation. Methods Meter Health, the developer and manufacturer of this patented product, used a purposive sampling approach to allow individuals with hiccups and a desire for hiccup palliation to purchase their agent and then to report on its efficacy or lack thereof. The authors of this report were provided these outcome data and allowed to analyze, report, and publish with no input from Meter Health with the exception of comments on accuracy. Results This report focused on 43 surveys that were completed. In response to the question, “Did the Hiccupops work for the person they were purchased for?” 29 (67%) responded, “yes.” Seven individuals (16%) responded, “no;” and 7 (16%) were “not sure.” Write-in comments appeared to substantiate the effective palliative nature of the intervention: “A friend with 10 days of hiccups following… brain tumor surgery, after 2 days, they stopped!!!#.” Another noted the following: “I like that if my hiccups get painful they’re there as a quick relief.” Less favorable comments were also noted: “She couldn’t get past the…. taste.” Another read as follows: “They were not effective in stopping my father’s intractable hiccups…. I like that there is someone out there who cares about trying to stop people’s hiccups.” Conclusions This patented product appears to palliate hiccups in some individuals and merits further study.

Adapt or Perish: How Forced Transition to Remote Simultaneous Interpreting during the COVID-19 Pandemic Affected Interpreters’ Professional Practices

This article discusses the results of a survey carried out among 132 simultaneous interpreters with Polish as their working language, summarising their professional experience during the first 10 months of the COVID-19 pandemic. In the context of the forced transition to the remote mode of simultaneous interpreting and the related technical and organisational challenges, this survey captured the early experience of working remotely (mostly from home), as well as the adaptations necessitated by the new situation in terms of changes in working modalities and tools, particularly in the home environment. The article also presents the surveyed interpreters’ expectations regarding the role and place of remote simultaneous interpreting in their future professional practices.
