Deane AS, Byers KT. A review of the ethical considerations for the use of 3D printed materials in medical and allied health education and a proposed collective path forward. ANATOMICAL SCIENCES EDUCATION 2024; 17:1164-1173. [PMID: 39001638 DOI: 10.1002/ase.2483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 06/11/2024] [Accepted: 06/13/2024] [Indexed: 08/30/2024]
Abstract
3D scanning and printing technologies are quickly evolving and offer great potential for use in gross anatomical education. The use of human body donors to create digital scans and 3D printed models raises ethical concerns about donor informed consent, potential commodification, and access to and storage of potentially identifiable anatomical reproductions. This paper reviews available literature describing ethical implications for the application of these emerging technologies, existing published best practices for managing and sharing 2D imaging, and current adherence to these best practices by academic body donation programs. We conclude that informed consent is paramount for all uses of human donor and human donor-derived materials and that currently there is considerable diversity in adherence to established best practices for the management and sharing of 3D digital content derived from human donors. We propose a new and simplified framework for categorizing donor-derived teaching materials and the corresponding level of consent required for digital sharing. This framework proposes an equivalent minimum level of specific consent for human donor and human donor-derived materials relative to generalized, nonidentical teaching materials (i.e., artificial plastic models). Likewise, we propose that the collective path forward should involve the creation of a centralized, secure repository for digital human donor 3D content as a mechanism for accumulating, regulating, and controlling the distribution of properly consented human donor-derived 3D digital content that will also increase the availability of ethically created human-derived teaching materials while discouraging commodification.

Horne CA, Hepworth D, Saunders E, Keenan ID. Everyone can draw: An inclusive and transformative activity for conceptualization of topographic anatomy. ANATOMICAL SCIENCES EDUCATION 2024; 17:1080-1096. [PMID: 38825620 DOI: 10.1002/ase.2460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 03/18/2024] [Accepted: 05/08/2024] [Indexed: 06/04/2024]
Abstract
Anatomical drawing traditionally involves illustration of labeled diagrams on two-dimensional surfaces to represent topographical features. Despite the visual nature of anatomy, many learners perceive that they lack drawing skills and do not engage in art-based learning. Recent advances in the capabilities of technology-enhanced learning have enabled the rapid and inexpensive production of three-dimensional anatomical models. This work describes a "drawing on model" activity in which learners observe and draw specific structures onto three-dimensional models. Sport and exercise sciences (SES, n = 79) and medical (MED, n = 156) students at a United Kingdom medical school completed this activity using heart and femur models, respectively. Learner demographics, their perceptions of anatomy learning approaches, the value of the activity, and their confidence in understanding anatomical features, were obtained via validated questionnaire. Responses to 7-point Likert-type and free-text items were analyzed by descriptive statistics and semi-quantitative content analysis. Learners valued art-based study (SES mean = 5.94 SD ±0.98; MED = 5.92 ± 1.05) and the "drawing on model" activity (SES = 6.33 ± 0.93; MED = 6.21 ± 0.94) and reported enhanced confidence in understanding of cardiac anatomy (5.61 ± 1.11), coronary arteries (6.03 ± 0.83), femur osteology (6.07 ± 1.07), and hip joint muscle actions (5.80 ± 1.20). Perceptions of learners were independent of both their sex and their art-based study preferences (p < 0.05). Themes constructed from free-text responses identified "interactivity," "topography," "transformative," and "visualization," as key elements of the approach, in addition to revealing some limitations. This work will have implications for anatomy educators seeking to engage learners in an inclusive, interactive, and effective learning activity for supporting three-dimensional anatomical understanding.

From 2D slices to a 3D model: Training students in digital microanatomy analysis techniques through a 3D printed neuron project. ANATOMICAL SCIENCES EDUCATION 2024; 17:499-505. [PMID: 38379173 DOI: 10.1002/ase.2396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 01/19/2024] [Accepted: 01/23/2024] [Indexed: 02/22/2024]
Abstract
The reconstruction of two-dimensional (2D) slices to three-dimensional (3D) digital anatomical models requires technical skills and software that are becoming increasingly important to the modern anatomist, but these skills are rarely taught in undergraduate science classrooms. Furthermore, learning opportunities that allow students to simultaneously explore anatomy in both 2D and 3D space are increasingly valuable. This report describes a novel learning activity that trains students to digitally trace a serially imaged neuron from a confocal stack and to model that neuron in 3D space for 3D printing. By engaging students in the production of a 3D digital model, this learning activity is designed to provide students a novel way to enhance their understanding of the content, including didactic knowledge of neuron morphology, technical research skills in image analysis, and career exploration of neuroanatomy research. Moreover, students engage with microanatomy in a way that starts in 2D but results in a 3D object they can see, touch, and keep. This discursive article presents the learning activity, including videos, instructional guides, and learning objectives designed to engage students on all six levels of Bloom's Taxonomy. Furthermore, this work is a proof of principle modeling workflow that is approachable, inexpensive, achievable, and adaptable to cell types in other organ systems. This work is designed to motivate the expansion of 3D printing technology into microanatomy and neuroanatomy education.

Canine Upper Digestive Tract 3D Model: Assessing Its Utility for Anatomy and Upper Endoscopy Learning. Animals (Basel) 2024; 14:1070. [PMID: 38612309 PMCID: PMC11010944 DOI: 10.3390/ani14071070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 03/28/2024] [Accepted: 03/29/2024] [Indexed: 04/14/2024] Open
Abstract
A teaching strategy using 3D-printed models of the canine upper digestive tract (UDT) for anatomy demonstration and upper endoscopy instruction was evaluated. The canine UDT (esophagus-stomach-duodenum) was scanned and 3D-printed molds were manufactured using silicone casting. First-year students were introduced to these 3D models in practical sessions alongside real specimens. Simultaneously, fifth-year students were trained in endoscope handling and anatomical recognition using 3D specimens. Both groups completed an anonymous survey. Results showed that overall, first-year (n = 93) and fifth-year (n = 45) students agreed or strongly agreed that the 3D-printed model was effective for learning purposes. In summary, first-year students highlighted an improved understanding of size, volume, topography, and easier manipulation of the 3D model compared to fresh specimens. Fifth-year students were more enthusiastic, finding the 3D model valuable for spatial vision and clinical training. While both groups were against completely replacing the natural UDT with the 3D model, first-year students were more hesitant. These findings suggest that the 3D model of the canine UDT is an effective tool for hands-on training in clinical endoscopy and a valuable, albeit complementary, resource for teaching anatomy and topography.

The Educational Impact of Radiology in Anatomy Teaching: A Field Study Using Cross-Sectional Imaging and 3D Printing for the Study of the Spine. Acad Radiol 2024; 31:329-337. [PMID: 37925345 DOI: 10.1016/j.acra.2023.10.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 09/26/2023] [Accepted: 10/09/2023] [Indexed: 11/06/2023]
Abstract
INTRODUCTION Cross-sectional imaging and 3D printing represent state-of-the-art approaches to improve anatomy teaching compared to traditional learning, but their use in medical schools remains limited. This study explores the utility of these educational tools for teaching normal and pathological spinal anatomy, aiming to improve undergraduate medical education. MATERIALS AND METHODS A field study was conducted on a cohort of undergraduate medical students who were exposed to anatomy lessons of the spine considering three learning paradigms: traditional learning, cross-sectional imaging examinations, and 3D printed models. 20 students (intervention group) received the three approaches, and other 20 students (control group) received the conventional (traditional) approach. The students were examined through a multiple-choice test and their results were compared to those of a control group exposed to traditional learning matched by age, sex and anatomy grades. In addition, students in the experimental group were assessed for their satisfaction with each learning method by means of an ad hoc questionnaire. RESULTS Students exposed to cross-sectional imaging and 3D printing demonstrated better knowledge outcomes compared to the control group. They showed high satisfaction rates and reported that these technologies enhanced spatial understanding and facilitated visualization of specific pathologies. However, limitations such as the representativeness of non-bone conditions in 3D printed models and the need for further knowledge on imaging fundamentals were highlighted. CONCLUSION Cross-sectional imaging and 3D printing offer valuable tools for enhancing the teaching of spinal anatomy in undergraduate medical education. Radiologists are well positioned to lead the integration of these technologies, and further research should explore their potential in teaching anatomy across different anatomical regions.

Abstract
BACKGROUND Three-dimensional-printed anatomical models (3DPAMs) appear to be a relevant tool due to their educational value and their feasibility. The objectives of this review were to describe and analyse the methods utilised for creating 3DPAMs used in teaching human anatomy and for evaluating its pedagogical contribution. METHODS An electronic search was conducted on PubMed using the following terms: education, school, learning, teaching, learn, teach, educational, three-dimensional, 3D, 3-dimensional, printing, printed, print, anatomy, anatomical, anatomically, and anatomic. Data retrieved included study characteristics, model design, morphological evaluation, educational performance, advantages, and disadvantages. RESULTS Of the 68 articles selected, the cephalic region was the most studied (33 articles); 51 articles mentioned bone printing. In 47 articles, the 3DPAM was designed from CT scans. Five printing processes were listed. Plastic and its derivatives were used in 48 studies. The cost per design ranged from 1.25 USD to 2800 USD. Thirty-seven studies compared 3DPAM to a reference model. Thirty-three articles investigated educational performance. The main advantages were visual and haptic qualities, effectiveness for teaching, reproducibility, customizability and manipulability, time savings, integration of functional anatomy, better mental rotation ability, knowledge retention, and educator/student satisfaction. The main disadvantages were related to the design: consistency, lack of detail or transparency, overly bright colours, long printing time, and high cost. CONCLUSION This systematic review demonstrates that 3DPAMs are feasible at a low cost and effective for teaching anatomy. More realistic models require access to more expensive 3D printing technologies and substantially longer design time, which would greatly increase the overall cost. Choosing an appropriate image acquisition modality is key. From a pedagogical viewpoint, 3DPAMs are effective tools for teaching anatomy, positively impacting the learning outcomes and satisfaction level. The pedagogical effectiveness of 3DPAMs seems to be best when they reproduce complex anatomical areas, and they are used by students early in their medical studies.

Effects of the individual three-dimensional printed craniofacial bones with a quick response code on the skull spatial knowledge of undergraduate medical students. ANATOMICAL SCIENCES EDUCATION 2023; 16:858-869. [PMID: 36905326 DOI: 10.1002/ase.2269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Revised: 03/06/2023] [Accepted: 03/06/2023] [Indexed: 06/18/2023]
Abstract
Understanding the three-dimensional (3D) structure of the human skull is imperative for medical courses. However, medical students are overwhelmed by the spatial complexity of the skull. Separated polyvinyl chloride (PVC) bone models have advantages as learning tools, but they are fragile and expensive. This study aimed to reconstruct 3D-printed skull bone models (3D-PSBs) using polylactic acid (PLA) with anatomical characteristics for spatial recognition of the skull. Student responses to 3D-PSB application were investigated through a questionnaire and tests to understand the requirement of these models as a learning tool. The students were randomly divided into 3D-PSB (n = 63) and skull (n = 67) groups to analyze pre- and post-test scores. Their knowledge was improved, with the gain scores of the 3D-PSB group (50.0 ± 3.0) higher than that of the skull group (37.3 ± 5.2). Most students agreed that using 3D-PSBs with quick response codes could improve immediate feedback on teaching (88%; 4.41 ± 0.75), while 85.9% of the students agreed that individual 3D-PSBs clarified the structures hidden within the skull (4.41 ± 0.75). The ball drop test revealed that the mechanical strength of the cement/PLA model was significantly greater than that of the cement or PLA model. The prices of the PVC, cement, and cement/PLA models were 234, 1.9, and 10 times higher than that of the 3D-PSB model, respectively. These findings imply that low-cost 3D-PSB models could revolutionize skull anatomical education by incorporating digital technologies like the QR system into the anatomical teaching repertoire.

Abstract
Currently, medicine uses typical industrial structure techniques, including reverse engineering, data processing, 3D-CAD modeling, 3D printing, and coordinate measurement techniques. Taking this into account, one can notice the applications of procedures used in the aviation or automotive industries based on the structure of Industry 4.0 in the planning of operations and the production of medical models with high geometric accuracy. The procedure presented in the publication shortens the processing time of tomographic data and increases the reconstruction accuracy within the hip and knee joints. The procedure allows for the partial removal of metallic artifacts from the diagnostic image. Additionally, numerical models of anatomical structures, implants, and bone cement were developed in more detail by averaging the values of local segmentation thresholds. Before the model manufacturing process, additional tests of the PLA material were conducted in terms of its strength and thermal properties. Their goal was to select the appropriate type of PLA material for manufacturing models of anatomical structures. The numerical models were divided into parts before being manufactured using the Fused Filament Fabrication technique. The use of the modifier made it possible to change the density, type of filling, number of counters, and the type of supporting structure. These treatments allowed us to reduce costs and production time and increase the accuracy of the printout. The accuracy of the manufactured model geometry was verified using the MCA-II measuring arm with the MMDx100 laser head and surface roughness using a 3D Talyscan 150 profilometer. Using the procedure, a decrease in geometric deviations and amplitude parameters of the surface roughness were noticed. The models based on the presented approach allowed for detailed and meticulous treatment planning.

Abstract
Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.

Abstract
The consolidation of technology as an alternative strategy to cadaveric dissection for teaching anatomy in medical courses was accelerated by the recent Covid-19 pandemic, which caused the need for social distance policies and the closure of laboratories and classrooms. Consequently, new technologies were created, and those already been developed started to be better explored. However, information about many of these instruments and resources is not available to anatomy teachers. This systematic review presents the technological means for teaching and learning about human anatomy developed and applied in medical courses in the last ten years, besides the infrastructure necessary to use them. Studies in English, Portuguese, and Spanish were searched in MEDLINE, Scopus, ERIC, LILACS, and SciELO databases, initially resulting in a total of 875 identified articles, from which 102 were included in the analysis. They were classified according to the type of technology used: three-dimensional (3D) printing (n = 22), extended reality (n = 49), digital tools (n = 23), and other technological resources (n = 8). It was made a detailed description of technologies, including the stage of the medical curriculum in which it was applied, the infrastructure utilized, and which contents were covered. The analysis shows that between all technologies, those related to the internet and 3D printing are the most applicable, both in student learning and the financial cost necessary for its structural implementation.

Abstract
Three-dimensional (3D) printing technology is a rapid prototyping method that has recently been increasingly used in anatomy education. Magnetic resonance imaging, computed tomography, and 3D scanners are generally used to create 3D models. The aim of this study, which was performed without using the aforementioned devices, is to design sheep scapula models in a computer environment and compare bone models created with different filaments printed by a 3D printer with real bone. Photographs of sheep scapula were taken for modelling, and measurements were made from certain points. After the photographs were transferred to a computer environment, they were transformed into 3D using the Cinema 4D software, a computer-aided design program. Models were created using a 3D printer employing polylactic acid (PLA) and thermoplastic polyurethane (TPU) filaments. By comparing the models created with PLA and TPU filaments to the real bone, it was found that they have a similar anatomical structure, with dimensional-morphometric differences found at some points. It was also observed that the scapula model created with PLA filaments was more resistant to impacts than the real bone and that the model created with TPU filaments was more flexible, with very low fragility as compared to PLA and real bone. Therefore, this method allows obtaining a large number of durable models as an alternative to the real bone without the need for much manpower or equipment and without the need for a 3D reconstruction device.

Abstract
While integrated delivery of anatomy and radiology can support undergraduate anatomical education, the interpretation of complex three-dimensional spatial relationships in cross-sectional and radiological images is likely to be demanding for novices. Due to the value of technology-enhanced and multimodal strategies, it was hypothesized that simultaneous digital and physical learning could enhance student understanding of cross-sectional anatomy. A novel learning approach introduced at a United Kingdom university medical school combined visualization table-based thoracic cross-sections and digital models with a three-dimensional printed heart. A mixed-method experimental and survey approach investigated student perceptions of challenging anatomical areas and compared the multimodal intervention to a two-dimensional cross-section control. Analysis of seven-point Likert-type responses of new medical students (n = 319) found that clinical imaging (mean 5.64 SD ± 1.20) was significantly more challenging (P < 0.001) than surface anatomy (4.19 ± 1.31) and gross anatomy (4.92 ± 1.22). Pre-post testing of students who used the intervention during their first anatomy class at medical school (n = 229), identified significant increases (P < 0.001) in thoracic cross-sectional anatomy interpretation performance (mean 31.4% ± 15.3) when compared to the subsequent abdominal control activity (24.1% ± 17.6). Student test scores were independent of mental-rotation ability. As depicted on a seven-point Likert-type scale, the intervention may have contributed to students considering cross-sectional interpretation of thoracic images (4.2 ± 1.23) as significantly less challenging (P < 0.001) than comparable abdominal images (5.59 ± 1.14). These findings could have implications for how multimodal cross-sectional anatomy learning approaches are implemented within medical curricula.

[PMID: 34685310 PMCID: PMC8540301 DOI: 10.3390/polym13203551] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/08/2021] [Accepted: 10/09/2021] [Indexed: 10/31/2022] Open
Abstract
Additive manufacturing (AM) is a disruptive technology that enables one to manufacture complex structures reducing both time and manufacturing cost. Among the materials commonly used for AM, thermoplastic elastomers (TPE) are of high interest due to their energy absorption capacity, energy efficiency, cushion factor or damping capacity. Previous investigations have exclusively focused on the optimization of the printing parameters of commercial TPE filaments and the structures to analyse the mechanical properties of the 3D printed parts. In the present paper, the chemical, thermal and mechanical properties for a wide range of commercial thermoplastic polyurethanes (TPU) filaments were investigated. For this purpose, TGA, DSC, 1H-NMR and filament tensile strength experiments were carried out in order to determine the materials characteristics. In addition, compression tests have been carried out to tailor the mechanical properties depending on the 3D printing parameters such as: infill density (10, 20, 50, 80 and 100%) and infill pattern (gyroid, honeycomb and grid). The compression tests were also employed to calculate the specific energy absorption (SEA) and specific damping capacity (SDC) of the materials in order to establish the role of the chemical composition and the geometrical characteristics (infill density and type of infill pattern) on the final properties of the printed part. As a result, optimal SEA and SDC performances were obtained for a honeycomb pattern at a 50% of infill density.

Abstract
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.

Abstract
For the past 20 years, the democratization of additive manufacturing (AM) technologies has made many of us dream of: low cost, waste-free, and on-demand production of functional parts; fully customized tools; designs limited by imagination only, etc. As every patient is unique, the potential of AM for the medical field is thought to be considerable: AM would allow the division of dedicated patient-specific healthcare solutions entirely adapted to the patients' clinical needs. Pertinently, this review offers an extensive overview of bone-related clinical applications of AM and ongoing research trends, from 3D anatomical models for patient and student education to ephemeral structures supporting and promoting bone regeneration. Today, AM has undoubtably improved patient care and should facilitate many more improvements in the near future. However, despite extensive research, AM-based strategies for bone regeneration remain the only bone-related field without compelling clinical proof of concept to date. This may be due to a lack of understanding of the biological mechanisms guiding and promoting bone formation and due to the traditional top-down strategies devised to solve clinical issues. Indeed, the integrated holistic approach recommended for the design of regenerative systems (i.e., fixation systems and scaffolds) has remained at the conceptual state. Challenged by these issues, a slower but incremental research dynamic has occurred for the last few years, and recent progress suggests notable improvement in the years to come, with in view the development of safe, robust and standardized patient-specific clinical solutions for the regeneration of large bone defects.

Abstract
Over the past decades, teaching and learning within the discipline of anatomy has undergone significant changes. Some of these changes are due to a reduction in the number of teaching hours, while others are related to advancements in technology. Faced with these many choices for change, it can be difficult for faculty to decide on which new developments in anatomical education need or indeed can be integrated into their course to enhance student learning. This article presents the universal design for learning (UDL) framework-an informed, evidence-based, and robust approach to underpin new course design and pedagogical reform in anatomy education. Universal design for learning is not a theory but a framework grounded in cognitive neuroscience that focuses on engaging multiple brain networks. The guidelines for UDL are organized into three core principles: (1) provide multiple means of representation, (2) provide multiple means of action and expression, and (3) provide multiple means of engagement. The learning space within the anatomy laboratory provides an excellent opportunity in which to apply this framework. This article also describes current trends employed in the teaching of anatomy. The principles of UDL are then outlined, followed by a description of how UDL approaches have been applied in the design and delivery of anatomy practical teaching to first year medical students at University College Cork. Future implications for this work are a consideration and investigation of how a course designed with the principles of UDL at its heart ultimately benefits student learning.

Abstract
Pediatric airway models currently available for use in education or simulation do not replicate anatomy or tissue responses to procedures. Emphasis on mass production with sturdy but homogeneous materials and low-fidelity casting techniques diminishes these models’ abilities to realistically represent the unique characteristics of the pediatric airway, particularly in the infant and younger age ranges. Newer fabrication technologies, including 3-dimensional (3D) printing and castable tissue-like silicones, open new approaches to the simulation of pediatric airways with greater anatomical fidelity and utility for procedure training.

Abstract
INTRODUCTION Macroscopic anatomy has traditionally been taught using cadaveric material, lectures and a variety of additional resources including online modules and anatomical models. Traditional plastic models are effective educational tools yet they have significant drawbacks such as a lack of anatomical detail, a lack of texturisation and cost. Three-dimensional printed models stand to solve these problems and widen access to high-quality anatomical teaching. This paper outlines the use of three-dimensional multiplanar imaging (computed tomography) in the development of an accurate model of the hepatobiliary system. MATERIALS AND METHODS Computed tomography scans were used to construct a virtual three-dimensional model of the hepatobiliary system. This was printed locally as a full-size colour model. We give a complete account of the process and software used. DISCUSSION This study is among the first of a series in which we will document the newly formed Oxford Library of Anatomy. This series will provide the methodology for the production of three-dimensional models from computed tomography and magnetic resonance imaging scans, and the library will provide a complete collection of the most complex anatomical areas. We hope that these models will form an important adjunct in teaching anatomy to medical students and surgical trainees.

Abstract
INTRODUCTION Three-dimensional (3D)-printed models have become increasingly popular as an alternative to the traditional method of cadaveric dissection in teaching anatomy. It has the advantage of lower cost and higher reproducibility. It has been widely used in the postgraduate setting, but its efficacy in undergraduate education has not been studied extensively. OBJECTIVES A scoping review of the literature was undertaken systematically to investigate the role of 3D printing in the anatomy education of undergraduate medical students. METHODS A systematic literature search of databases (EMBASE, Pubmed, Educational Resources Information Center, British Education Index and Australian Education Index) was undertaken using relevant keywords. RESULTS The search yielded 83 results, which were narrowed down to 13 articles after application of exclusion criteria. The literature supported that 3D printing was a useful tool for studying normal, uncommon and pathological anatomy. However, limitations include low fidelity in replicating the colour and textural physical properties of soft tissues and the trade-off between cost and fidelity. CONCLUSIONS It is believed that 3D printing would increasingly be integrated into undergraduate anatomy education, and it might also potentially be used in the assessment of anatomical knowledge and clinical skills training. The establishment of an online 3D model database may facilitate educators to easily manufacture models for specific educational purposes.

Abstract
The pterygopalatine fossa (PPF) is a bilateral space deep within the skull that serves as a major neurovascular junction. However, its small volume and poor accessibility make it a difficult space to comprehend using two-dimensional illustrations and cadaveric dissections. A three-dimensional (3D) printed model of the PPF was developed as a visual and kinesthetic learning tool for completely visualizing the fossa, its boundaries, its communicating channels, and its neurovascular structures. The model was evaluated by analyzing student performance on pre- and post-quizzes and a student satisfaction survey based on the five-point Likert scale. The first cohort comprised of 88 students who had never before studied the PPF. The second cohort consisted of 30 students who were previously taught the PPF. Each cohort was randomly divided into a control group who were provided with a half skull and an intervention group that were provided with the 3D printed model. The intervention group performed significantly better on the post-quiz as compared to the control group in cohort I (P = 0.001); while not significant, it also improved learning in cohort II students (P = 0.124). Satisfaction surveys indicated that the intervention group found the 3D printed model to be significantly more useful (P < 0.05) as compared to the half skull used by the control group. Importantly, the effect sizes for cohorts I and II (0.504 and 0.581, respectively) validated the statistical results. Together, this study highlights the importance of 3D printed models as teaching tools in anatomy education.

Abstract
PURPOSE In this face validity study, we discuss the fabrication and utility of an affordable, computed tomography (CT)-based, anatomy-accurate, 3-dimensional (3D) printed temporal bone models for junior otolaryngology resident training. MATERIALS AND METHODS After IRB exemption, patient CT scans were anonymized and downloaded as Digital Imaging and Communications in Medicine (DICOM) files to prepare for conversion. These files were converted to stereolithography format for 3D printing. Important soft tissue structures were identified and labeled to be printed in a separate color than bone. Models were printed using a desktop 3D printer (Ultimaker 3 Extended, Ultimaker BV, Netherlands) and polylactic acid (PLA) filament. 10 junior residents with no previous drilling experience participated in the study. Each resident was asked to drill a simple mastoidectomy on both a cadaveric and 3D printed temporal bone. Following their experience, they were asked to complete a Likert questionnaire. RESULTS The final result was an anatomically accurate (XYZ accuracy = 12.5, 12.5, 5 μm) 3D model of a temporal bone that was deemed to be appropriate in tactile feedback using the surgical drill. The total cost of the material required to fabricate the model was approximately $1.50. Participants found the 3D models overall to be similar to cadaveric temporal bones, particularly in overall value and safety. CONCLUSIONS 3D printed temporal bone models can be used as an affordable and inexhaustible alternative, or supplement, to traditional cadaveric surgical simulation.

Abstract
OBJECTIVE To assess the effect of 3-dimensional (3D)-printed surgical simulators used in an advanced pediatric otolaryngology fellowship preparatory course on trainee education. STUDY DESIGN Quasi-experimental pre/postsurvey. SETTING Multicenter collaborative course conducted at a contract research organization prior to a national conference. SUBJECTS AND METHODS A 5-station, 7-simulator prep course was piloted for 9 pediatric otolaryngology fellows and 17 otolaryngology senior residents, with simulators for airway graft carving, microtia ear framework carving, and cleft lip/palate repair. Prior to the course, trainees were provided educational materials electronically along with presurveys rating confidence, expertise, and attitude around surgical simulators. In October 2018, surgeons engaged in simulation stations with direction from 2 attending faculty per station, then completed postsurveys for each simulator. RESULTS Statistically significant increases (P < .05) in self-reported confidence (average, 53%; range, 18%-80%) and expertise (average, 68%; range, 9%-95%) were seen across all simulators, corresponding to medium to large effect sizes as measured by Cohen's d statistic (0.41-1.71). Positive attitudes around 3D printing in surgical education also demonstrated statistically significant increases (average, 10%; range, 8%-13%). Trainees commented positively on gaining such broad exposure, although consistently indicated a preference for more practice time during the course. CONCLUSION We demonstrate the benefit of high-fidelity, 3D-printed simulators in exposing trainees to advanced procedures, allowing them hands-on practice in a zero-risk environment. In the future, we hope to refine this course design, develop standardized tools to assess their educational value, and explore opportunities for integration into use in milestone assessment and accreditation.

Abstract
Background Recent advances in 3D printing technology, and biomaterials are revolutionizing medicine. The beneficiaries of this technology are primarily patients, but also students of medical faculties. Taking into account that not all students have full, direct access to the latest advances in additive technologies, we surveyed their opinion on 3D printing and education in this area. The research aimed to determine what knowledge about the use of 3D printing technology in medicine, do students of medical faculties have. Methods The research was carried out in the form of a questionnaire among 430 students of the Medical University of Silesia in Katowice (Poland) representing various fields of medicine and health sciences. The questions included in the survey analyzed the knowledge of the respondents for 3D printing technology and the opportunities it creates in medicine. Results The results indicate that students do have knowledge about 3D printing obtained mainly from the internet. They would be happy to deepen their knowledge at specialized courses in this field. Students appreciated the value of 3D printing in order to obtain accurate anatomical models, helpful in learning. However, they do not consider the possibility of complete abandonment of human cadavers in the anatomy classes. Their knowledge includes basic information about current applications of 3D printing in medicine, but not in all areas. However, they have no ethical doubts regarding the use of 3D printing in any form. The vast majority of students deemed it necessary to incorporate information regarding 3D printing technology into the curriculum of different medical majors. Conclusion This research is the first of its kind, which allows for probing students' knowledge about the additive technologies in medicine. Medical education should be extended to include issues related to the use of 3D printing for medical applications.

Development of a three-dimensional printed heart from computed tomography images of a plastinated specimen for learning anatomy. Anat Cell Biol 2020; 53:48-57. [PMID: 32274249 PMCID: PMC7118264 DOI: 10.5115/acb.19.153] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Revised: 09/20/2019] [Accepted: 09/26/2019] [Indexed: 02/06/2023] Open
Abstract
Learning anatomy is commonly facilitated by use of cadavers, plastic models and more recently three-dimensional printed (3DP) anatomical models as they allow students to physically touch and hold the body segments. However, most existing models are limited to surface features of the specimen, with little opportunity to manipulate the structures. There is much interest in developing better 3DP models suitable for anatomy education. This study aims to determine the feasibility of developing a multi-material 3DP heart model, and to evaluate students' perceptions of the model. Semi-automated segmentation was performed on computed tomgoraphy plastinated heart images to develop its 3D digital heart model. Material jetting was used as part of the 3D printing process so that various colors and textures could be assigned to the individual segments of the model. Morphometric analysis was conducted to quantify the differences between the printed model and the plastinated heart. Medical students' opinions were sought using a 5-point Likert scale. The 3DP full heart was anatomically accurate, pliable and compressible to touch. The major vessels of the heart were color-coded for easy recognition. Morphometric analysis of the printed model was comparable with the plastinated heart. Students were positive about the quality of the model and the majority of them reported that the model was useful for their learning and that they would recommend their use for anatomical education. The successful feasibility study and students' positive views suggest that the development of multi-material 3DP models is promising for medical education.

Abstract
In recent decades, three-dimensional (3D) printing as an emerging technology, has been utilized for imparting human anatomy knowledge. However, most 3D printed models are rigid anatomical replicas that are unable to represent dynamic spatial relationships between different anatomical structures. In this study, the data obtained from a computed tomography (CT) scan of a normal knee joint were used to design and fabricate a functional knee joint simulator for anatomical education. Utility of the 3D printed simulator was evaluated in comparison with traditional didactic learning in first-year medical students (n = 35), so as to understand how the functional 3D simulator could assist in their learning of human anatomy. The outcome measure was a quiz comprising 11 multiple choice questions based on locking and unlocking of the knee joint. Students in the simulation group (mean score = 85.03%, ±SD 10.13%) performed significantly better than those in the didactic learning group, P < 0.05 (mean score = 70.71%, ±SD 15.13%), which was substantiated by large effect size, as shown by a Cohen's d value of 1.14. In terms of learning outcome, female students who used 3D printed simulators as learning aids achieved greater improvement in their quiz scores as compared to male students in the same group. However, after correcting for the modality of instruction, the sex of the students did not have a significant influence on the learning outcome. This randomized study has demonstrated that the 3D printed simulator is beneficial for anatomical education and can help in enriching students' learning experience.

Abstract
New technological developments have frequently had major consequences for anatomy education, and have raised ethical queries for anatomy educators. The advent of three-dimensional (3D) printing of human material is showing considerable promise as an educational tool that fits alongside cadaveric dissection, plastination, computer simulation, and anatomical models and images. At first glance its ethical implications appear minimal, and yet the more extensive ethical implications around clinical bioprinting suggest that a cautious approach to 3D printing in the dissecting room is in order. Following an overview of early groundbreaking studies into 3D printing of prosections, organs, and archived fetal material, it has become clear that their origin, using donated bodies or 3D files available on the Internet, has ethical overtones. The dynamic presented by digital technology raises questions about the nature of the consent provided by the body donor, reasons for 3D printing, the extent to which it will be commercialized, and its comparative advantages over other available teaching resources. In exploring questions like these, the place of 3D printing within a hierarchical sequence of value is outlined. Discussion centers on the significance of local usage of prints, the challenges created by regarding 3D prints as disposable property, the importance of retaining the human side to anatomy, and the unacceptability of obtaining 3D-printed material from unclaimed bodies. It is concluded that the scientific tenor of 3D processes represents a move away from the human person, so that efforts are required to prevent them accentuating depersonalization and commodification.

Abstract
Background Medical simulation is an emerging field for resident training. Three-dimensional printing has accelerated the development of models for spine surgical simulation. Previous models have utilized augmented infill ratios to simulate the density difference between cortical and cancellous bone; however, this does not fully account for differences in the material properties of these components of human vertebrae. In order to replicate the differences in both density and material characteristics for realistic spinal simulation, we created a three-dimensional model composed of multiple thermoplastic polymers. Materials and methods Three lumbar vertebrae and 20 C2 vertebrae models using an experimental dual material fabrication method were printed on an Ultimaker S5 3D printer. Assessment of model integrity during instrumentation as well as user tactile feedback were points of interest to determine prototype viability for educational and biomechanical use. The experimental cohort was compared with a control cohort consisting of a single material print, resin print, and polyurethane mold. Results Based on tactile feedback, the experimental dual material print (polylactic acid [PLA]/polyvinyl alcohol [PVA]) more accurately represented the sensation of in vivo instrumentation during pedicle probing, pedicle tapping, and screw placement. There were no instrumentation or material failures in the PLA/PVA experimental model cohort. Conclusions This feasibility study indicates that multiple material printing using PLA and PVA is a viable method to replicate the cortico-cancellous interface in vertebral models. This concept and design using our unique infill algorithm have not been yet reported in the medical literature. Further educational and biomechanical testing on our design is currently underway to establish this printing method as a new standard for spinal biomimetic modeling.

Abstract
Advances in consumer-level educational technologies show great promise for enhancing the learning experiences of students in health and medicine. There are particular benefits to using a combination of various devices and technologies when teaching challenging concepts. These include augmented reality-enabled devices enriched with accompanying 3D printed models, or virtual reality sessions coupled with online quizzes or revision activities. Tablet applications can also be integrated while students engage concurrently in desktop-based online learning. This mixing and merging of different technologies can allow educators to focus on the strengths of each device, while mitigating limitations arising from a single mode's stand-alone use. This chapter describes a series of options to integrate multiple digital modes when educating health science and medical students using technology. It also presents the opportunity for health professional program graduates to be trained in teaching using technology, as their future careers can be enhanced by an ability to educate effectively, or from the skills developed when incorporating innovations such as serious games into a health curriculum. With the dynamic and ever-changing nature of health and medical education, educators can find great benefits when introducing multimodal digital learning into their respective courses.

Abstract
The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

Abstract
Objective To investigate the impact of using a three-dimensional (3D) printed liver model for patient education. Methods Children with hepatic tumours who were scheduled for hepatectomy were enrolled, and patient-specific 3D liver models were printed with photosensitive resin, based on computed tomography (CT) images. Before surgery, their parents received information regarding liver anatomy, physiology, tumour characteristics, planned surgery, and surgical risks using these CT images. Then, parents completed questionnaires regarding this information. Thereafter, 3D printed models of each patient were presented along with an explanation of the general printing process, and the same questionnaire was completed. The median number of correct responses in each category before and after the 3D printed model presentation was compared. Results Seven children and their 14 parents were enrolled in the study. After the presentation of 3D printed models, parental understanding of basic liver anatomy and physiology, tumour characteristics, the planned surgical procedure, and surgical risks significantly improved. Parents demonstrated improvements in their understanding of basic liver anatomy by 26.4%, basic liver physiology by 23.6%, tumour characteristics by 21.4%, the planned surgical procedure by 31.4%, and surgical risks by 27.9%. Conclusions Using 3D printed liver models improved parental education regarding the understanding of liver anatomy and physiology, tumour characteristics, surgical procedure, and associated surgical risks.
