The Covid-19 pandemic has challenged medical educators internationally to confront the challenges of adapting their present educational activities to a rapidly evolving digital world. In this article, the authors use anatomy education as proxy to reflect on and remap the past, present, and future of medical education in the face of these disruptions. Inspired by the historical Theatrum Anatomicum (Anatomy 1.0), the authors argue replacing current anatomy dissection laboratory (Anatomy 2.0) with a prototype anatomy studio (Anatomy 3.0). In this studio, anatomists are web-performers who not only collaborate with other foundational science educators to devise meaningful and interactive content but who also partner with actors, directors, web-designers, computer engineers, information technologists, and visual artists to master online interactions and processes in order to optimize students' engagement and learning. This anatomy studio also offers students opportunities to create their own online content and thus reposition themselves digitally, a step into developing a new competency of stage presence within medical education. So restructured, Anatomy 3.0 will prepare students with the skills to navigate an emergent era of tele and digital medicine as well as help to foreshadow forthcoming changes in medical education.

The clinical use of ultrasound has dramatically increased, necessitating early ultrasound education and the development of new tools in ultrasound training and assessment. The goal of this study was to devise a novel low-resource examination that tested the anatomical knowledge and technical skill of early undergraduate medical students in a gross anatomy course. The team-based ultrasound objective structured practice examination (OSPE) was created as a method for assessing practical ultrasound competencies, anatomical knowledge, and non-technical skills such as teamwork and professionalism. The examination utilized a rotation of students through four team roles as they scanned different areas of the body. This station-based examination required four models and four instructors, and tested ultrasound skills in the heart, abdominal vessels, abdominal organs, and neck regions. A Likert scale survey assessed student attitudes toward the examination. Survey data from participants (n = 46) were examined along with OSPE examination grades (n = 52). Mean and standard deviations were calculated for examination items and survey responses. Student grades were high in both technical (96.5%). and professional (96.5%) competencies with structure identification scoring the lowest (93.8%). There were no statistical differences between performances in each of the body regions being scanned. The survey showed that students deemed the examination to be fair and effective. In addition, students agreed that the examination motivated them to practice ultrasound. The team-based OSPE was found to be an efficient and student-favored method for evaluating integrated ultrasound competencies, anatomical knowledge, team-work, and professional attributes.

Advanced postgraduate medical education for health-care professionals is constantly evolving. Understanding facial anatomy and especially its vascular system is crucial when performing soft tissue filler injections to avoid adverse events including tissue loss or irreversible blindness. Standard anatomical resources often fall short of elucidating clinically relevant concepts in more highly specialized areas of interest. A novel dissection approach for demonstrating the anatomy of the lateral orbit was presented at scientific meetings to participants from dermatology, plastic surgery, and general practice. Results from the post-course online survey (n = 52) were analyzed. The results of the survey reveal a high educational impact and a high clinical relevance of the novel dissection approach. In addition, the majority of respondents (97.7%; n = 51) felt that the exposed anatomical structure of the orbit and face improved their ability to safely perform cosmetic procedures on the face. More experienced respondents who had previously attended at least five cadaveric dissections were more likely to strongly agree that reviewing anatomy through this novel dissection approach increased their confidence in avoiding periorbital vascular danger zones. As minimally invasive outpatient procedures continue to evolve, practicing physicians and mid-level providers often face the challenge of having to reconcile preexisting anatomical knowledge with new clinical practice. Skills required to navigate high impact anatomy include visualization of structures that form the navigational landscape and avoidance of key danger zones. The novel dissection approach to the lateral orbit reflects the increasing focus on revisiting, reforming, and redesigning anatomy for continuing professional development activities.

Background: Ultrasound education has been provided to students in medical schools within and beyond the United States. A formal experiment with use of personal handheld ultrasound equipment by all first-year medical students has not been reported. Employing insonation (an application of ultrasound) at the personal leisure by medical school freshmen enables self-directed learning throughout the academic year. Methods: We describe a peer-led ultrasound curriculum with handheld devices. The students' perceptions were gathered through quarterly Likert-style questionnaires, and the differences in the categories were tested using Analysis of Variance. Results: The response rate was 58.5% for the first survey (n = 32), 56% (n = 30) for the second survey, and 62.3% (n = 33) for the final survey, respectively, with an average response rate of 58.9%. At the baseline survey, overall agreement was observed for enhancement on performance (62.5%) and interpretation (56.3) of ultrasounds, understanding (68.8%) and learning of anatomy (61.3%), ease (78.1%), comfort (59.4%) and benefit of incorporation of insonation in the medical school curricula (all p-values < 0.001). Neutral response (38.7%) or disagreement (38.7%) was observed when assessing the effect of the integration in medical curriculum on specialty choice (p < 0.01). These trends remained constant over follow-up with the exception that the perceived benefit for integration of insonation into the longitudinal curricula (p < 0.05) increased significantly over time. Majority of disagreement was observed regarding current access to the personal ultrasound devices (38.7%) (p < 0.001). Conclusions: The introduction of insonation through personal handheld ultrasound devices in the first-year medical school curriculum was received enthusiastically by students, with the majority of respondents finding the devices both easy to use and a valuable aid to improving their understanding of the three-dimensional anatomy.

This article explores the assessment of professionalism within a cohort of medical students during a sequential 13-week medical school histology and anatomy course. Across seven data points, students were asked to identify a professionalism role model from amongst their peers and to score Likert-structured rationales for their decision. Based on density scores, an initial social network analysis identified six peer-nomination "stars." However, analysis of these stars revealed considerable variability and random-like "noise" in both the nomination and explanation data sets. Subsequent analyses of both data sets explored the possibility of underlying patterns in this noise using tests of reliability, principal components factor analysis, and fixed-effects regression analysis. These explorations revealed the presence of two dimensions (professional vs. supportive) in how students sought to explain their nomination decisions. Although data variability remained quite high, significantly less variability was present in the professional than in the supportive dimension, suggesting that academic helpfulness rationales are both empirically distinct and more mutable than rationales grounded in professionalism-related factors. In addition, data showed that the greater the stability in one's choice of a professionalism role model nomination over the T1-T7 data periods, the more stable one's reasons for that nomination-both for professionalism and supportive dimensions. Results indicate that while peer assessment of professionalism by first-year medical students may not be very reliable, students can differentiate between more personal and professional factors, even at this early stage in their professional development. Formal instruction within the pre-clinical curriculum should recognize and address this distinction. Anat Sci Educ. © 2018 American Association of Anatomists.

OBJECTIVES: Local anesthetic injection into the interspace between the popliteal artery and the posterior capsule of the knee (IPACK) has the potential to provide motor-sparing analgesia to the posterior knee after total knee arthroplasty. The primary objective of this cadaveric study was to evaluate injectate spread to relevant anatomic structures with IPACK injection. METHODS: After receipt of Institutional Review Board Biospecimen Subcommittee approval, IPACK injection was performed on fresh-frozen cadavers. The popliteal fossa in each specimen was dissected and examined for injectate spread. RESULTS: Ten fresh-frozen cadaver knees were included in the study. Injectate was observed to spread in the popliteal fossa at a mean ± SD of 6.1 ± 0.7 cm in the medial-lateral dimension and 10.1 ± 3.2 cm in the proximal-distal dimension. No injectate was noted to be in contact with the proximal segment of the sciatic nerve, but 3 specimens showed injectate spread to the tibial nerve. In 3 specimens, the injectate showed possible contact with the common peroneal nerve. The middle genicular artery was consistently surrounded by injectate. CONCLUSIONS: This cadaver study of IPACK injection demonstrated spread throughout the popliteal fossa without proximal sciatic involvement. However, the potential for injectate to spread to the tibial or common peroneal nerve was demonstrated. Consistent surrounding of the middle genicular artery with injectate suggests a potential mechanism of analgesia for the IPACK block, due to the predictable relationship between articular sensory nerves and this artery. Further study is needed to determine the ideal site of IPACK injection.

Quality of healthcare delivery is dependent on collaboration between professional disciplines. Integrating opportunities for interprofessional learning in health science education programs prepares future clinicians to function as effective members of a multi-disciplinary care team. This study aimed to create a modified team-based learning (TBL) environment utilizing ultrasound technology during an interprofessional learning activity to enhance musculoskeletal anatomy knowledge of first year medical (MD) and physical therapy (PT) students. An ultrasound demonstration of structures of the upper limb was incorporated into the gross anatomy courses for first-year MD (n = 53) and PT (n = 28) students. Immediately before the learning experience, all students took an individual readiness assurance test (iRAT) based on clinical concepts regarding the assigned study material. Students observed while a physical medicine and rehabilitation physician demonstrated the use of ultrasound as a diagnostic and procedural tool for the shoulder and elbow. Following the demonstration, students worked within interprofessional teams (n = 14 teams, 5-6 students per team) to review the related anatomy on dissected specimens. At the end of the session, students worked within interprofessional teams to complete a collaborative clinical case-based multiple choice post-test. Team scores were compared to the mean individual score within each team with the Wilcoxon signed-rank test. Students scored higher on the collaborative post-test (95.2 ±10.2%) than on the iRAT (66.1 ± 13.9% for MD students and 76.2 ±14.2% for PT students, P < 0.0001). Results suggest that this interprofessional team activity facilitated an improved understanding and clinical application of anatomy.

OBJECTIVES: To identify any anatomic barriers to local anesthetic spread between the sciatic nerve (SN) and the posterior femoral cutaneous nerve (PFCN) at the level of the infragluteal crease and to describe a potential technique for an ultrasound (US)-guided subgluteal PFCN block in a cadaveric model. METHODS: Bilateral US-guided subgluteal injections of a colored latex solution were performed around the SN (15 mL) and PFCN (10 mL) in 4 unembalmed cadavers, for a total of 8 cadaver thighs. The specimens were dissected after latex polymerization to observe the spread of the latex solutions. RESULTS: With US guidance, the PFCN was visualized deep to the gluteus maximus and slightly superficial or lateral to the SN at the level of the infragluteal crease. The SN and PFCN were found on dissection to be coated with their respective colored latex in all 8 thighs. The SN and PFCN were consistently separated by the deep investing muscular fascia of the thigh, with only 2 thighs showing substantial mixing of latex injectates. CONCLUSIONS: The deep investing muscular fascia of the thigh appears to impede the spread of injectate between the SN and PFCN in a most unembalmed cadaver specimens. A US-guided subgluteal PFCN blockade may be a feasible technique to complement an SN block when complete anesthesia of the posterior thigh is required.
