Musculoskeletal Anatomy Education: Evaluating the Influence of Different Teaching and Learning Activities on Medical Students Perception and Academic Performance

Visible Human Project based applications can prompt integrating cross-sectional anatomy into the medical school curriculum when combined with radiological modalities: A three-year cross-sectional observational study

BACKGROUND

Cross-sectional anatomy is a challenging yet a vital foundation to clinical practice. The traditional teachings of gross anatomy cadaveric dissections do not cover adequate training of recognizing anatomical structures on CT, MRI and sonographic cross-sections. New modern technologies are emerging as teaching tools in anatomy aiming to deliver visual interactive experience. The Visible Human Project provides a library of cross-sectional images compiled from cryosectioned body donors that was utilized by modern technologies such as the virtual dissection table (Anatomage) in constructing 3D software applications visualizing the internal composition of the human body virtually. Hereby, this article explores an integrative approach utilizing the Visible Human Project based applications and basic radiological modalities.

PURPOSE

The purpose of our newly implemented teaching approach was to test and assure technology fitness to the medical curriculum and its potential influence on students' performance in learning gross as well as cross-sectional anatomy in much depth.

BASIC PROCEDURES

A three years (2021-2024) observational study was conducted by implanting a practical cross-sectional anatomy optional course by selectively utilizing Anatmage interactively beside CT, MRI and ultrasound practice. The performance of 50 participants was evaluated in the form of a written test comprised of labeling of ten cross-sectional images and drawing of two cross-section schemes. Their optional course test scores were compared to their obligatory anatomy subject test scores; and to a non-participants control group of 50 retrospective obligatory anatomy subject test scores. In addition, the participants' attitude toward the training lessons was assessed through a survey focused on satisfaction level, competence and ability to recognize structures on radiological images.

MAIN FINDINGS

The participants reported a high level of practical engagement. The test scores in the anatomy obligatory subject were positively influenced by this implemented practical course. Students showed improved test scores in the standardized labeling keyword questions, while the scheme questions showed discrepancy.

PRINCIPAL CONCLUSIONS

Integrating Visible Human Project based applications with radiological modalities showed positive efficacy on the students' engagement and learning performance. Inevitably, cadaveric dissection and prosection remain the cornerstone of gross anatomy education. Integrating both modalities of teaching would excel students' practical skills in applied clinical anatomy.

A call for improving of musculoskeletal education on physical medicine and rehabilitation studies: a systematic review with meta-analysis

BACKGROUND

The incidence of musculoskeletal diseases is increasing in clinical practice, leading to a growing demand for rehabilitation medicine. However, education in musculoskeletal education is lacking in the training of physical medicine and rehabilitation students. This study aims to evaluate the impact of musculoskeletal education on medical students' learning of rehabilitation medicine and analyze the correlation between influencing factors and education.

OBJECTIVES

The primary objective of this study is to evaluate the impact of musculoskeletal education on medical students' learning of rehabilitation medicine. Furthermore, the authors aim to analyze the correlation between various influencing factors and the effectiveness of this education, with the goal of informing future educational interventions and enhancing student outcomes.

METHODS

A comprehensive search was conducted across the Pubmed, Ovid, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for relevant articles published from January 2012 to September 2024. The search focused on medical students as the research subjects and musculoskeletal education as the intervention method. Both randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) were included. The selected studies underwent a systematic review, and meta-analysis was performed using R 3.4.4 software.

RESULTS

After a thorough search, 41 studies were included. The retrospective study indicated that the most common impacts were knowledge acquisition, self-confidence, and satisfaction. The subsequent meta-analysis revealed significant increases in students' knowledge acquisition [standardized mean differences (SMD) = 2.15, 95% confidence interval [CI] (1.36, 2.94), I2 = 97%, random effect model] and self-confidence [SMD = 5.81, 95% CI (2.88, 8.75), I2 = 97%, random effect model]. Compared with the general teaching control group, the knowledge acquisition of students in the observation group improved [SMD = 0.25, 95% CI (0.00, 0.51), I2 = 83%, in the random effect model]; However, no significant difference in satisfaction occurred [SMD = 0.27, 95% CI (-0.47, 1.01), P > 0.05, I2 = 89%, in the random effects model].

CONCLUSION

Musculoskeletal education primarily impacts knowledge acquisition self-confidence, and satisfaction among physical medicine and rehabilitation students. The meta-analysis further establishes that musculoskeletal education significantly enhances knowledge acquisition and confidence in these students.

Musculoskeletal Learning and Knowledge Retention Among Postgraduate Physicians: Evaluating the Long-Term Impact of a New Preclerkship Curriculum at a Nationally Accredited Medical Program

Introduction

Musculoskeletal (MSK) injuries and disorders are exceptionally prevalent in the clinical setting. Despite this, physician training in MSK medicine has been historically inadequate contributing to a lack of MSK knowledge, confidence, and clinical skills among postgraduate physicians. The goal of this investigation was to examine the long-term impact of a new preclerkship MSK curriculum implemented by a nationally accredited medical program on postgraduate physician's learning and knowledge retention in the area of MSK medicine.

Methods

Five hundred sixty-eight postgraduate physicians (years 1-6) who had previously completed the new curriculum over a 6-year period were recruited to complete a standardized and validated MSK examination that consisted of 30 multiple-choice questions on core or must-know topics in MSK medicine that could be directly mapped to learning objectives within the new preclerkship MSK curriculum.

Results

Ninety postgraduate physicians completed the examination, obtaining an average score of 75.0% (±10.2; range 57.0-100.0). Physicians who completed MSK-related electives during clerkship training or specialized in fields related to MSK medicine (i.e., orthopaedics, PM&R, sports medicine, and rheumatology) performed significantly better on the MSK examination (p ≤ 0.01).

Conclusion

Data indicated that the program's new preclerkship curriculum supports high levels of MSK learning and knowledge retention among postgraduate physicians. These findings are expected to assist with the establishment of minimum curriculum standards and can be used to guide MSK curricular reform at other medical programs.

Addressing musculoskeletal curricular inadequacies within undergraduate medical education

BACKGROUND

Musculoskeletal (MSK) injuries and diseases place a significant burden on the health care system. Despite this, research indicates that physician training in the area of MSK medicine has historically been inadequate, with a majority of medical students feeling that their training in MSK medicine is lacking. The goal of this investigation was to evaluate the efficacy of a new preclinical MSK curriculum that was implemented within a nationally accredited allopathic medical program.

METHODS

Retrospective analysis was completed on five consecutive years (2017-2021) of preclinical MSK curricular data for 549 medical students, including mid and end-of-course examinations and end-of-course student satisfaction surveys. Both parametric and non-parametric methods of analysis were used to examine within and between class differences (P < 0.05).

RESULTS

The new MSK curriculum covered 15 of 16 "core or must know" topics in MSK medicine, and academic performance was consistently high over the 5-year period of analysis (final course marks ranged from 76.6 ± 7.1 to 81.4 ± 8.1; failures/year: range from 0 to 4), being equal or above levels of student performance observed for other courses delivered during preclinical studies. Likert data from end-of-course surveys demonstrated that feedback was overwhelmingly positive (overall course satisfaction ranged from a low of 3.07/4.00 to a high of 3.56/4.00) and indicated that students felt that the new preclinical MSK curriculum did effectively support medical student learning and knowledge retention.

CONCLUSION

Results are expected to help advance the current body of knowledge that is dedicated to improving physician learning and knowledge retention in the area of MSK medicine and provides a curricular model that could be used by other nationally accredited medical programs to help enhance MSK learning at the preclinical levels of physician training.

Inadequacies in Undergraduate Musculoskeletal Education-A Survey of Nationally Accredited Allopathic Medical Programs in Canada

OBJECTIVE

The aim of the study is to document the current state of musculoskeletal (MSK) medicine education across nationally accredited undergraduate medical programs.

DESIGN

A cross-sectional survey design was used to gather curricular data on the following three musculoskeletal themes: (1) anatomy education, (2) preclinical education, and (3) clerkship education.

RESULTS

The survey had a 100% response rate with all 14 English-language medical schools in Canada responding. The mean time spent teaching musculoskeletal anatomy was 29.8 hrs (SD ± 13.7, range = 12-60), with all but one program using some form of cadaveric-based instruction. Musculoskeletal preclinical curricula averaged 58.0 hrs (SD ± 53.4, range = 6-204), with didactic lectures, case-based learning, and small group tutorials being the most common modes of instruction. Curricular content varied greatly, with only 25% of "core or must-know" musculoskeletal topics being covered in detail by all programs. Musculoskeletal training in clerkship was required by only 50% of programs, most commonly being 2 wks in duration.

CONCLUSIONS

Results document the large variability and curricular inadequacies that exist in musculoskeletal education across nationally accredited allopathic programs and highlight the need for the identification and implementation of more consistent musculoskeletal curricular content and educational standards by all nationally accredited medical programs.

Comparative Analysis of Multidimensional Learning Tools in Anatomy: A Randomized Control Trial

INTRODUCTION

Anatomy teaching has traditionally been based on dissection. However, reduced hours in total and laboratory hours in gross anatomy along with a dearth of cadavers have ensued the search for a less time-consuming tool.

MATERIALS AND METHODS

The study was conducted in the Department of Anatomy in Sheikh Bhikhari Medical College, Hazaribag. A total of 282 medical students were taught gross anatomy, using three different learning modalities: dissection (n = 95), plastic models (n = 94), and three-dimensional (3D) anatomy software (n = 93). The knowledge of the students was examined by 100 multiple-choice question (MCQ) and tag questions followed by an evaluation questionnaire.

RESULTS

When performance is considered, the dissection and 3D group performed better than the plastic models group in total, MCQs, and tag questions. In the evaluation questionnaire, dissection performed better than the other two modalities. Moreover, dissection and 3D software emerged as superior to the plastic models group.

STATISTICAL ANALYSIS

All data were analyzed using the one-way ANOVA and t-test. Group-based analysis by ANOVA and gender-based analysis were done by Student's t-test. A comparison of students' perceptions was done by Kruskal-Wallis H-test.

CONCLUSION

Dissection remains a favorite with students and accomplishes a significantly higher attainment of knowledge. Plastic models are less effective but are a valuable tool in preparation for cadaveric laboratories.

Residents' Perceptions of a Novel Virtual Livestream Cadaveric Teaching Series for Musculoskeletal Anatomy Education

ABSTRACT

Musculoskeletal anatomy education is essential to many healthcare providers but has consistently been considered difficult for various reasons. Traditional methods have focused on in-person cadaveric teaching, which became inaccessible during the COVID-19 pandemic; therefore, new teaching methods were developed to address this gap in education. This project implemented novel virtual livestream musculoskeletal anatomy teaching methodology with cadaveric prosections and evaluated the efficacy of this modality compared with traditional in-person cadaveric teaching. A targeted musculoskeletal anatomy curriculum was developed and delivered via livestream to 12 Canadian physiatry residents. Upon completing the virtual curriculum, residents completed an anonymous survey assessing this new virtual livestream cadaveric methodology compared with previous experiences with traditional in-person anatomy teaching. The survey response rate was 92%. Most participants (73%) rated the virtual livestream sessions as better than traditional in-person teaching. Reasons included better visualization of cadaveric anatomy and easy discussion among the group. T test analysis comparing both methods demonstrated the livestream method was equivalent or better across several domains. Virtual livestream teaching is a viable method for teaching the important subject of musculoskeletal anatomy. Educators should consider how to best integrate this approach into future anatomy curricula.

Consolidation Carnival: A Case-Based Approach to Reviewing Musculoskeletal Anatomy in an Undergraduate Medical Curriculum

Introduction

Recent changes in undergraduate medical curricula have resulted in time constraints that are particularly challenging, especially when students must learn large blocks of musculoskeletal anatomy content. Consequently, students have resorted to rote memorization to cope, which counteracts our established collaborative self-directed learning model.

Methods

For a 6-week musculoskeletal anatomy course, two structured case-based review sessions are described, each following the completion of two five-hour lab sessions, two on the upper extremities and two on the lower extremities. These largely self-directed review sessions consisted of 6 students rotating through 7 to 8 stations every 10 minutes where clinical cases with follow-up questions were projected on large screens. The students were expected to work collaboratively to solve the cases utilizing the prosected specimens provided and discuss the accompanying answers at the end of each case.

Results

Ninety-four per cent of the students who participated in this study agreed that the case-based review sessions provided a helpful overview of musculoskeletal anatomy content. Student performance on the open-ended, case-based musculoskeletal examination questions showed no significant difference in performance on shoulder, hand, hip, thigh, and leg questions. There was, however, a statistically significant decrease in the students' scores on a forearm question in 2021 compared to 2019.

Conclusion

This paper describes our integrated, collaborative musculoskeletal course, including case-based review sessions, which was positively received by students as having value in reviewing the musculoskeletal content though it was not found to improve examination performance.

A History of Musculoskeletal Medicine and Its Place and Progress in Undergraduate Medical Education

Musculoskeletal diseases are responsible for some of the most prevalent conditions affecting population health in the world. Despite the prevalence of these conditions, musculoskeletal medicine has a fraught history within the world of undergraduate medical education. We review the origins of musculoskeletal medicine, its evolution in undergraduate medical education, and progress that has been made over the last decade as a result of global initiatives such as the Bone and Joint Decade. Understanding the history of musculoskeletal medicine is essential to contextualizing the problems that exist today and creating comprehensive solutions to fill the gaps that persist in musculoskeletal curricula.

Transforming musculoskeletal anatomy learning with haptic surface painting

Anatomical body painting has traditionally been utilized to support learner engagement and understanding of surface anatomy. Learners apply two-dimensional representations of surface markings directly on to the skin, based on the identification of key landmarks. Esthetically satisfying representations of musculature and viscera can also be created. However, established body painting approaches do not typically address three-dimensional spatial anatomical concepts. Haptic Surface Painting (HSP) is a novel activity, distinct from traditional body painting, and aims to develop learner spatial awareness. The HSP process is underpinned by previous work describing how a Haptico-visual observation and drawing method can support spatial, holistic, and collaborative anatomy learning. In HSP, superficial and underlying musculoskeletal and vascular structures are located haptically by palpation. Transparent colors are then immediately applied to the skin using purposive and cross-contour drawing techniques to produce corresponding visual representations of learner observation and cognition. Undergraduate students at a United Kingdom medical school (n = 7) participated in remote HSP workshops and focus groups. A phenomenological study of learner perspectives identified four themes from semantic qualitative analysis of transcripts: Three-dimensional haptico-visual exploration relating to learner spatial awareness of their own anatomy; cognitive freedom and accessibility provided by a flexible and empowering learning process; altered perspectives of anatomical detail, relationships, and clinical relevance; and delivery and context, relating to curricular integration, session format, and educator guidance. This work expands the pedagogic repertoire of anatomical body painting and has implications for anatomy educators seeking to integrate innovative, engaging, and effective learning approaches for transforming student learning.

Musculoskeletal education in undergraduate medical curricula-A systematic review

Rheumatic and musculoskeletal diseases encompass a vast spectrum of up to 200 conditions that are increasingly prevalent, with significant associated disability and socioeconomic burden. Their impact is pervasive, with musculoskeletal conditions being the second leading cause of years lived with disability worldwide, in addition to the 9th most common cause of disability-adjusted life years. It is therefore imperative that all graduating medical physicians are competent in their management, and that the quality of undergraduate musculoskeletal education is commensurate with patient and societal needs. A systematic literature review was conducted between April 1, 2021 and June 1, 2021 assessing the quality of undergraduate musculoskeletal education in medical schools. Educational interventions in musculoskeletal medicine were also included. Quality assessment appraisal of the studies was done using a Mixed Methods Appraisal Tool. One thousand and thirty-three titles were screened, and 44 studies were included in the final analysis. Our analysis of these studies showed that the quality of undergraduate musculoskeletal education, as determined by the cognitive mastery and clinical confidence of undergraduate medical students remains inadequate. Multiple educational interventions were assessed with mixed results. Despite the prevalence, and burden associated with rheumatic and musculoskeletal diseases, the musculoskeletal education of undergraduate medical students remains inadequate. Urgent international collaboration is required to devise teaching strategies and curriculum initiatives that are globally and reproducibly applicable and effective. Further research into educational interventions and teaching strategies is also required.

A randomized trial comparing cadaveric dissection and examination of prosections as applied surgical anatomy teaching pedagogies

Anatomy is an important component in the vertical integration of basic science and clinical practice. Two common pedagogies are cadaveric dissection and examination of prosected specimens. Comparative studies mostly evaluate their immediate effectiveness. A randomized controlled trial design was employed to compare both the immediate and long-term effectiveness of dissection and prosection. Eighty third-year medical students undergoing their surgical rotation from the Yong Loo Lin School of Medicine were randomized into two groups: dissection and prosection. Each participated in a one-day hands-on course following a similar outline that demonstrated surgical anatomy in the context of its clinical relevance. A pre-course test was conducted to establish baseline knowledge. A post-course test was conducted immediately after and at a one-year interval to evaluate learner outcome and knowledge retention. A post-course survey was conducted to assess participant perception. Thirty-nine and thirty-eight participants for the dissection and prosection groups, respectively, were included for analysis. There was no significant difference between mean pre-course test scores between the dissection and prosection groups [12.6 (3.47) vs. 12.7 (3.16), P > 0.05]. Both the mean immediate [27.9 (4.30) vs. 24.9 (4.25), P < 0.05] and 1 year [23.9 (4.15) vs. 19.9 (4.05), P < 0.05] post-course test scores were significantly higher in the dissection group. However, when adjusted for course duration [dissection group took longer than prosection group (mean 411 vs. 265 min)], these findings were negated. There is no conclusive evidence of either pedagogy being superior in teaching surgical anatomy. Based on learner surveys, dissection provides a greater learner experience.

Dynamic three-dimensional virtual environment to improve learning of anatomical structures

Increasing number of medical students and limited availability of cadavers have led to a reduction in anatomy teaching through human cadaveric dissection. These changes triggered the emergence of innovative teaching and learning strategies in order to maximize students learning of anatomy. An alternative approach to traditional dissection was presented in an effort to improve content delivery and student satisfaction. The objective of this study is to acquire three-dimensional (3D) anatomical data using structured-light surface scanning to create a dynamic four-dimensional (4D) dissection tool of four regions: neck, male inguinal and femoral areas, female perineum, and brachial plexus. At each dissection step, identified anatomical structures were scanned using a 3D surface scanner (Artec Spider™). Resulting 3D color meshes were overlaid to create a 4D (3D+time) environment. An educational interface was created for neck dissection. Its implementation in the visualization platform allowed 4D virtual dissection by navigating from surface to deep layers and vice versa. A group of 28 second-year medical students and 17 first-year surgery residents completed a satisfaction survey. A majority of medical students (96.4%) and 100% of surgery residents said that they would recommend this tool to their colleagues. According to surgery residents, the main elements of this virtual tool were the realistic high-quality of 3D acquisitions and possibility to focus on each anatomical structure. As for medical students, major elements were the interactivity and entertainment aspect, precision, and accuracy of anatomical structures. This approach proves that innovative solutions to anatomy education can be found to help to maintain critical content and student satisfaction in anatomy curriculum.

Breaking barriers: The landscape of human and veterinary medical anatomy education and the potential for collaboration

Despite human (HUM) and veterinary (VET) medical institutions sharing the goal of educating future clinicians, there is little collaboration between them regarding curricular and pedagogical practices during the preclinical/basic science training years. This may be, at least in part, due to a lack of understanding of each type of curriculum. This study presents data about curricula, student populations, pedagogical methodologies applied, and anatomy educators' training at both HUM and VET institutions. Preclinical curricula, admissions criteria, and student demographics were analyzed for 21 institutions in the United States having both HUM and VET schools. This dataset was augmented by a questionnaire sent to anatomists internationally, detailing anatomy curricula, pedagogies applied, and anatomy educators' training. Many curricular similarities between both training programs were identified, including anatomy education experiences. However, VET programs were found to include more preclinical coursework than HUM programs. Students who matriculate to VET or HUM schools have similar academic records, including prerequisite coursework and grade point average. Median HUM class size was significantly larger, and the percentage of women enrolled in VET institutions was significantly higher. Training of anatomy educators was identical with one exception: VET educators are far more likely to hold a clinical degree. This study elucidates the substantial similarities between VET and HUM programs, particularly in anatomy education, underscoring the potential for collaboration between both types of programs in areas such as interprofessional education, bioethics, zoonotic disease management, and postgraduate training.

Student Perceptions of the Use of Case-Based Cadaver Dissections in Doctorate of Physical Therapy Program

Case-based cadaver dissection offers students unique opportunities to blend traditional anatomic knowledge acquisition with clinical reasoning. Twelve physical therapy students completed surveys centered on case-based dissections. Case-based cadaver dissections were defined in this study as multiple clinical vignettes that required students to use the accessible cadavers to solve clinically based problems. The results of the study provide preliminary evidence that students perceive case-based cadaver dissections as beneficial to their anatomy education and beneficial to the development of their clinical reasoning skills.

Modern and synchronized clinical anatomy teaching based on the BDIE method (board-digital dissection-imaging-evaluation)

PURPOSE

Anatomy has historically been taught via traditional medical school lectures and dissection. In many countries, practical or legal issues limit access to cadaveric dissection. New technologies are favored by students and could improve learning, complementing traditional teaching.

METHODS

All students in second-year medicine at a single medical school were submitted to a novel anatomical course with digital tool exposure. We explored a new combined teaching method: a physical blackboard lesson synchronized with digital dissection, imaging and direct evaluation (BDIE). Synchronized dissection is broadcast live in the classroom and in partner medical schools. Following the course, students completed a short survey about their perception of this new anatomic clinical course.

RESULTS

The survey included 183 students whom 178 completed the questionnaire, i.e., a 97% response rate. Ninety-nine percent of students thought this synchronized method useful to improve their understanding of anatomy and 90% stated it helped them retain this learning.

CONCLUSION

This BDIE method, in conjunction with teaching guidelines and dissection, is highly appreciated by students who consider it helps them to acquire lasting knowledge.

The Association Between Preclinical Medical Students' Perceptions of the Anatomy Education Environment and Their Learning Approaches

This study aimed to measure medical students' perceptions of the anatomy education environment and determine its association with their learning approaches. First- and second-year undergraduate medical students (N = 234) completed the Anatomy Education Environment Measurement Inventory and the Approaches and Study Skills Inventory for Students. Results revealed that the students' perceptions of all the factors in the anatomy education environment were positive except for two areas-the anatomy learning resources and quality of histology learning facilities. The majority of students in the first year (62.3%) and second year (43.7%) adopted a deep learning approach. There was no significant association between most of the factors in the anatomy education environment and the students' learning approaches, except for the students' intrinsic interest in learning anatomy factor (p = 0.032). The anatomy education environment was positive for the medical students, and there was a prevalence of a deep learning approach among them. However, most of the factors in the anatomy education environment did not influence the students' learning approach. Given that the students' learning approach is a multifactorial construct, investigating the relationship between these two variables in longitudinal time points would provide better insight into the association between the anatomy educational climate and students' learning approaches.

Three-Dimensional Printing Model Enhances Craniofacial Trauma Teaching by Improving Morphologic and Biomechanical Understanding: A Randomized Controlled Study

BACKGROUND

Teaching about craniofacial traumas is challenging given the complexity of the craniofacial anatomy and the necessity for good spatial representation skills. To solve these problems, three-dimensional printing seems to be an appropriate educative material. In this study, the authors conducted a randomized controlled trial. The authors' main objective was to compare the performance of the undergraduate medical students in an examination based on the teaching support: three-dimensionally printed models versus two-dimensional pictures.

METHODS

All participants were randomly assigned to one of two groups using a random number table: the three-dimensionally-printed support group (three-dimensional group) or the two-dimensionally-displayed support group (two-dimensional group). All participants completed a multiple-choice question evaluation questionnaire on facial traumatology (first, a zygomatic bone fracture; then, a double mandible fracture). Sex and potential confounding factors were evaluated.

RESULTS

Four hundred thirty-two fifth-year undergraduate medical students were enrolled in this study. Two hundred six students were allocated to the three-dimensional group, and 226 were allocated to the two-dimensional group. The three-dimensionally printed model was considered to be a better teaching material compared with two-dimensional support. The global mean score was 2.36 in the three-dimensional group versus 1.99 in the two-dimensional group (p = 0.008). Regarding teaching of biomechanical aspects, three-dimensionally-printed models provide better understanding (p = 0.015). Participants in both groups exhibited similar previous student educational achievements and visuospatial skills.

CONCLUSIONS

This prospective, randomized, controlled educational trial demonstrated that incorporation of three-dimensionally-printed models improves medical students' understanding. This trial reinforces previous studies highlighting academic benefits in using three-dimensionally-printed models mostly in the field of understanding complex structures.

Issues in Teaching Vascular Anatomy: Thoughts and Suggestions from the Clinician's Point of View

The role of anatomy in modern curricula is under reform due to competency of other rapidly evolving subjects and the rapid evolution of several practical aspects and applications dictating modernization of teaching methods as well as of teaching demands. Moreover, modern practice of medicine has put the arterial and vascular system in the center of numerous minimally invasive techniques. Therefore, regardless of their specialty, most doctors should have a very clear and precise knowledge of the vascular anatomy and the basic access techniques from the early years. This viewpoint commentary reflects the experience of the two authors in applying the principles and content of surgical vascular anatomy in undergraduate anatomy teaching and discusses the rationale of this. Moreover, it is suggested that cadaveric dissections should be modified with emphasis on standard surgical vascular exposures and the multidisciplinary teaching of vascular anatomy as a means not only to gain optimal long-term knowledge retention, but also to emphasize through realistic examples on the practical clinical value of vascular anatomy.

Efficacy of Video-Based Forearm Anatomy Model Instruction for a Virtual Education Environment

INTRODUCTION

As virtual education becomes more widespread, particularly considering the recent COVID-19 pandemic, studies that assess the impact of online teaching strategies are vital. Current anatomy curriculum at Paul L. Foster School of Medicine consists of self-taught PowerPoint material, clinical vignette-centered team-based learning (dry lab), and prosection-based instruction (wet lab). This study examined the impact of video-based muscle model (VBMM) instruction using a student-designed forearm muscle model on anatomy quiz scores and student perceptions of its effectiveness with regards to learning outcomes.

METHODS

Students divided into Group 1 (54 students) and Group 2 (53 students) were assessed prior to and following a 3.5-minute video on anterior forearm compartment musculature using the muscle model. Group 1 began by completing a pretest, then received VBMM instruction, and then completed a posttest prior to participating in the standard dry lab and 1 hour wet lab. Group 2 completed the wet lab, then received the pretest, VBMM instruction, and posttest prior to participating in the dry lab. Both groups took an identical five-question quiz covering locations and functions of various anterior forearm muscles each time.

RESULTS

Mean scores were higher than no formal intervention with exposure to VBMM instruction alone (0.73 points, P = .01), wet lab alone (0.88 points, P = .002), and wet lab plus VBMM instruction (1.35 points, P= <.001). No significant difference in scores was found between instruction with VBMM versus wet lab alone (P = 1.00), or between either instruction method alone compared to a combination of the two methods (P = .34, .09). Student survey opinions on the VBMM instruction method were positive.

CONCLUSION

VBMM instruction is comparable to prosection-based lab with regards to score outcomes and was well received by students as both an independent learning tool and as a supplement to cadaveric lab. When compared to either instruction method alone, the supplementation of VBMM with cadaveric prosection instruction was best. VBMM instruction may be valuable for institutions without access to cadaveric specimens, or those looking to supplement their current anatomy curriculum.

Musculoskeletal Educational Resources for the Aspiring Orthopaedic Surgeon

Musculoskeletal (MSK) education is underemphasized in medical school curricula, which can lead to decreased confidence in treating MSK conditions and suboptimal performance on orthopaedic surgery elective rotations or subinternships. Given the low amount of formalized education in MSK medicine, students aiming to learn about orthopaedic surgery must gain much of their foundational knowledge from other resources. However, there are currently no centralized introductory educational resources to fill this need. We provide a framework for navigating the different types of resources available for trainees and highlight the unaddressed needs in this area.

Creation of Anatomically Correct and Optimized for 3D Printing Human Bones Models

Educational institutions in several countries state that the education sector should be modernized to ensure a contemporary, individualized, and more open learning process by introducing and developing advance digital solutions and learning tools. Visualization along with 3D printing have already found their implementation in different medical fields in Pauls Stradiņš Clinical University Hospital, and Rīga Stradiņš University, where models are being used for prosthetic manufacturing, surgery planning, simulation of procedures, and student education. The study aimed to develop a detailed methodology for the creation of anatomically correct and optimized models for 3D printing from radiological data using only free and widely available software. In this study, only free and cross-platform software from widely available internet sources has been used—“Meshmixer”, “3D Slicer”, and “Meshlab”. For 3D printing, the Ultimaker 5S 3D printer along with PLA material was used. In its turn, radiological data have been obtained from the “New Mexico Decedent Image Database”. In total, 28 models have been optimized and printed. The developed methodology can be used to create new models from scratch, which can be used will find implementation in different medical and scientific fields—simulation processes, anthropology, 3D printing, bioprinting, and education.

Efficacy of an intensive 2-week musculoskeletal anatomy course in a medical education setting

There is little consistency in student contact hours and teaching activities used in medical curriculums across North America, and controversy exists regarding the most efficient or effective way to teach musculoskeletal (MSK) anatomy in medical school. The purpose of this investigation was to retrospectively examine academic performance and levels of course satisfaction among first year medical students who had completed an intensive 2-week MSK anatomy course during the pre-clerkship portion of their Association of Faculties of Medicine in Canada accredited undergraduate medical program. Course data from formative and summative student evaluations, as well as end-of-course satisfaction surveys were analyzed for a homogenous group of 549 first-year medical students over a 5-year period. Data indicated that student's academic performance on both formative and summative evaluations for the 2-week MSK anatomy course were consistently high, and not significantly different from the results for other system-based 1^st year anatomy courses delivered over longer durations. Likert data from end-of-course surveys also suggested that student feedback regarding the course was overwhelmingly positive, and that the 2-week MSK anatomy course had the highest level of overall satisfaction when compared to all other first-year anatomy courses. These results can be used to help in the design and implementation of MSK anatomy courses within medical curriculums, and contribute to a growing body of literature which is focused on examining the effect of curricular design on MSK anatomy learning in a medical education setting.

Dissection versus Prosection: A Comparative Assessment of the Course Experiences, Approaches to Learning, and Academic Performance of Non-medical Undergraduate Students in Human Anatomy

Many institutions rely upon prosection-based laboratories as more resource-efficient and time-effective alternatives to traditional cadaver dissection for human anatomy education. To facilitate growing enrollment numbers despite resource limitations, the University of Guelph (a non-medical institution) introduced a modified "stepwise" prosection-based laboratory cohort to supplement a dissection-based course. In this design, all students attended the same lectures, but those in the dissection-based cohort learned by performing regional dissections and students in the prosection-based cohort studied from those dissections. Prosection students thereby witnessed a "slow reveal" of structures throughout the course. This study compared the perceived course experiences, student approaches to learning, and academic performance between the two groups. Multiple linear regression analyses were used to isolate the effect of the laboratory environment on student approaches to learning and academic performance from demographic and situational covariates. Both groups reported positive course experience ratings and high average final grades that were not statistically dissimilar (P > 0.05), increased reliance on deep approaches to learning (P = 0.002), and decreased reliance on surface approaches to learning (P = 0.023). When controlling for covariates, participation in dissection had small but statistically significant positive associations with deep approaches to learning (P = 0.043), performance on laboratory oral assessments (P < 0.001), and average final grades (P = 0.039). Ultimately, both designs promoted meaningful learning and desirable performance outcomes, indicating that both dissection and stepwise prosection have the potential to facilitate high quality human anatomy instruction.

Musculoskeletal anatomy: evaluation and comparison of common teaching and learning modalities

Anatomy teaching has traditionally been based on dissection. However, alternative teaching modalities constantly emerge, the use of which along with a decrease in teaching hours has brought the anatomy knowledge of students and young doctors into question. In this way, the goal of the present study is to a. compare the efficacy of the most common teaching modalities and b. investigate students' perceptions on each modality. In total, 313 medical students were taught gross anatomy of the upper limb, using four different learning modalities: dissection (n = 80), prosections (n = 77), plastic models (n = 84) and 3D anatomy software (n = 72). Students' knowledge was examined by 100 multiple-choice and tag questions followed by an evaluation questionnaire. Regarding performance, the dissection and the 3D group outperformed the prosection and the plastic models group in total and multiple-choice questions. The performance of the 3D group in tag questions was also statistically significantly higher compared to the other three groups. In the evaluation questionnaire, dissection outperformed the rest three modalities in questions assessing students' satisfaction, but also fear or stress before the laboratory. Moreover, dissection and 3D software were considered more useful when preparing for clinical activities. In conclusion, dissection remains first in students' preferences and achieves higher knowledge acquisition. Contemporary, 3D anatomy software are considered equally important when preparing for clinical activities and mainly favor spatial knowledge acquisition. Prosections could be a valuable alternative when dissection is unavailable due to limited time or shortage of cadavers. Plastic models are less effective in knowledge acquisition but could be valuable when preparing for cadaveric laboratories. In conclusion, the targeted use of each learning modality is essential for a modern medical curriculum.

An Alternative Method for Anatomy Training: Immersive Virtual Reality

The aim of this study was to investigate the effect of immersive three-dimensional (3D) interactive virtual reality (VR) on anatomy training in undergraduate physical therapy students. A total of 72 students were included in the study. The students were randomized into control (n = 36) and VR (n = 36) group according to the Kolb Learning Style Inventory, sex, and Purdue Spatial Visualization Test Rotations (PSVT-R). Each student completed a pre-intervention and post-intervention test, consisting of 15 multiple-choice questions. There was no significant difference between the two groups in terms of age, sex, Kolb Learning Style Inventory distribution, and the PSVT-R (P > 0.05). The post-test scores were significantly higher compared to pre-test scores in both the VR group (P < 0.001) and the control group (P < 0.001). The difference between the pre-test and post-test results was found to be significantly higher in favor of the VR group (P < 0.001). In this study, anatomy training with a 3D immersive VR system was found to be beneficial. These results suggest that VR systems can be used as an alternative method to the conventional anatomy training approach for health students.

Learning musculoskeletal anatomy through new technologies: a randomized clinical trial

Objective:

to investigate the influence of the application of new methodologies on learning and the motivation of students of the Anatomy discipline.

Method:

randomized, longitudinal, prospective, intervention study. Sixty-two students were recruited to assess the impact of different methodologies. The sample was randomized to compare the results of teaching with a 3D atlas, ultrasound and the traditional method. The parameters were assessed through a satisfaction evaluation questionnaire and anatomical charts. Repeated measures ANOVA was used to determine statistical significance.

Results:

in terms of the usefulness of the seminars, 98.1% of the students considered them to be very positive or positive, stating that they had stimulated their interest in anatomy. The students who learned with the 3D atlas improved their understanding of anatomy (p=0.040). In general, the students improved their grades by around 20%.

Conclusion:

the traditional method combined with new technologies increases the interest of students in human anatomy and enables them to acquire skills and competencies during the learning process.

Australian chiropractors' perception of the clinical relevance of anatomical sciences and adequacy of teaching in chiropractic curricula

Background

Human anatomy education is compulsory in the undergraduate curriculum in all Australian chiropractic education programs. There is very little data on clinicians’ perceptions of the adequacy of their anatomy training and its relevance to practice. The aims of this study were to evaluate Australian registered chiropractors’ perceptions on the relevance and adequacy of anatomy training for clinical practice and analyse their opinion on the usefulness of the teaching resources utilized during their preprofessional training.

Methods

A questionnaire-based survey was conducted on a sample of Australian registered chiropractors focussing on the adequacy of their anatomical science (gross anatomy, histology, neuroanatomy and embryology) training and the clinical relevance of each individual sub-discipline, and the perceived value of each of the different anatomy teaching resources utilized.

Results

A total of 128 completed surveys were returned from an estimated 387 attendees at two national chiropractic conferences (estimated 33% response rate). The respondents represent 2.6% of registered chiropractors in Australia in 2016 and were representative in terms of gender (66.4% male) but not age, with older generations being over-represented (peak age group 35–44 vs. 25–34). The majority of the survey respondents obtained their chiropractic qualification in Australia (89.1%) and graduated after 1990 with an average of 21.7 years (SD = 11.3, range = 1–44) in practice. Respondents were equally likely to have undertaken anatomy training in Medicine, Science, Health Science, or other faculties. The disciplines perceived most relevant for clinical practice were neuroanatomy (100% of respondents agreeing) and gross anatomy (99.2%), followed by histology (86.0%) and embryology (81.1%). Respondents also perceived their training to be most adequate in neuroanatomy (99.3%) and gross anatomy (99.2%) followed by histology (91.4%) and embryology (85%). Respondents confirmed exposure to a varied suite of anatomy teaching tools utilized during their pre-professional training and highly valued access to cadavers and prosected specimens.

Conclusions

The majority of respondents perceived anatomy as highly relevant to their clinical practice and noted that it was adequately taught within a wide range of educational approaches. These results will assist educators to refine content and delivery of anatomy course offerings to maximize relevance in chiropractic clinical practice.

The Superficial Face Dissection as an Example for Integrating Clinical Approaches, Authentic Learning, and Changing Perspectives in Anatomy Dissection

Hands-on dissection-based learning of anatomy offers an unique and valued experience for medical students. Too often however, the inexperienced student's focus is to avoid damage to unfamiliar structures instead of understanding spatial relationships between structures. This results in unfortunate surrender of a critical learning experience. Additionally, approaches to dissection and anatomic exposure share little alignment to clinical approaches, making it less powerful in clinical applicability. The goal of this viewpoint commentary is based on the experience of the two authors and aims to demonstrate opportunity to introduce clinical approaches for dissection while incorporating relevant anatomical concepts in medical school curriculum that aligns with authentic healthcare practice. Using the dissections of the superficial face as a relevant and current topic of clinical interest, we point out that applying the currently performed dissection approach (medial-to-lateral) falls short of providing sufficient knowledge and understanding of the layered arrangement of facial structures. The lateral-to-medial approach, as performed in surgical face lifting procedures would offer a better understanding of the layers of the face and especially the superficial musculoaponeurotic system (SMAS) accounting for the difficulties of facial dissections on embalmed cadavers. This commentary could offer a potential change in paradigm for students and course facilitators for how to maximize the knowledge transfer during facial dissections. It potentially opens a door to rethink dissection-based learning of anatomy toward techniques and approaches that are aligned to surgical access pathways and thus considered more clinically relevant.

Anatomical Sciences in Chiropractic Education: A Survey of Chiropractic Programs in Australia

Human anatomy knowledge is a core requirement for all health care clinicians. There is a paucity of information relating to anatomy content and delivery in Australian chiropractic programs. The aim of this study was to describe anatomy teaching in Australian chiropractic programs, utilizing a survey which was distributed to all four programs, requesting information on: anatomy program structure, delivery methods, assessment, teaching resources, and academic staff profile at their institution. The survey was undertaken in 2016 and documented practices in that academic year. All four institutions responded. There was a reported difference in the teaching hours, content, delivery and assessment of anatomy utilized in Australian chiropractic programs. Anatomy was compulsory at all four institutions with the mean total of 214 (SD ± 100.2) teaching hours. Teaching was undertaken by permanent ongoing (30%) and sessional academic staff, and student to teacher ratio varied from 15:1 to 12:1. A variety of teaching resources were utilized, including human tissue access, either as prosected cadavers or plastinated body parts. The results of this survey confirm that anatomy has an established place in chiropractic education programs in Australia and while curricular variations exist, all programs had similar course design, delivery, and assessment methods. This study confirmed the provision of a strong foundation in topographical anatomy and neuroanatomy, while other anatomical sciences, such as histology and embryology were not consistently delivered. Formalization of a core anatomy curriculum together with competency standards is needed to assist program evaluation and development, and for accreditation purposes.
