Anatomists' uses of human skeletons: Ethical issues associated with the India bone trade and anonymized archival collections

American Association for Anatomy recommendations for the management of legacy anatomical collections

Collections of human remains in scientific and private institutions have a long tradition, though throughout history there has often been variable regard for the respect and dignity that these tissues demand. Recent public scandals around the use of human remains, coupled with an increasing community awareness around accountability in such instances, forces scholars to confront the ethical and moral concerns associated with these collections. This includes specific focus on the acquisition, storage, use, and disposition of these remains, which were often collected with no consent and with little knowledge, or concern, about the individual or their respective culture and practices surrounding death and postmortem treatment. As a response, the American Association for Anatomy convened a Legacy Anatomical Collections Task Force to consider these issues and to develop recommendations to assist those working with these tissues in education, research, and museum collections. This has culminated with the development of Recommendations for the Management of Legacy Anatomical Collections. The recommendations provide both an ethical foundation and practical considerations for the use, storage, and disposition of legacy collections of human tissues, and deliver guidance for establishing appropriate management and oversight, investigating provenance, and engaging with communities of care. While these Recommendations are considered a living document which will change over time as ethical principles concerning human tissue evolve, they currently represent 'best practice' recommendations that can guide researchers, teachers, and museum associates as they consider the future of legacy anatomical collections in their care.

The disposability and inclusion of Brown bodies

While there has been increased awareness of the ethics of curation, research, and teaching with human skeletal remains, there has been little recognition of the millions of skeletal remains from South Asia that were harvested illegally and/or unethically for educational institutions globally for over a century. This article gives a contextualization of the unique history and nature of anatomical teaching collections, and why they are an important locus for a decolonized and antiracist biological anthropology. I present the historical background of how the exportation and commodification of Indian bodies came to dominate the global bone trade. I also discuss how historical necropolitics explicitly erased the identity and objectified South Asian people made into study skeletons, and the way our current practices continue to uphold colonial violence. Finally, I discuss what we might do with these historical collections and the ways that inclusion of Brown voices is critical to ethical practice.

"I've got yer back": A community art and anatomy project

This article describes a community collaborative project, "I've got yer back," that utilized the craft of needle felting to raise awareness and develop understanding of the anatomy of the human spine. The project took place in 2023 and engaged with participants from across the United Kingdom and abroad and its completion was timed to coincide with National Back Health Awareness week in October 2023. We describe the process of creating a vertebra using needle felt and examine how the particularities of the process and the use of the sense of touch helped participants notice and understand the complex form of the human vertebra. We consider how the project encompassed creative processes of hands-on learning to enhance knowledge about this aspect of human anatomy. We discuss how the project evolved to include public and academic participation in a shared goal and argue for the effectiveness of seemingly simple and straightforward art or craft workshops in teaching relatively complex science. The article includes detailed feedback from participants who reflect on the process of learning through making and how it went on to affect individuals in very different, and sometimes very personal, ways.

From Data to Design: Constructing Scapula and Hip Bone Through Online Datasets, Open-Source Software and 3D Printers

Introduction Human skeletons and bones are essential for medical and allied sciences students. Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster-of-Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the "New Mexico Decedent Image Database". After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post-processing, the final physical model obtained has all the features. Conclusions We conclude that it is possible to produce anatomically accurate models with the greatest possible resemblance and accuracy to the original bones using free and open-source data with an FDM 3D printer.

Macro and micro ethics in fetal and embryological collections: Exploring the paradigms of informed consent among Australian education-focused stakeholders

The management of human fetal and embryological collections presents an ethical challenge that can be explored from different perspectives, particularly when considering informed consent. The "micro ethics" level focuses on parties engaged in giving and receiving human tissue while the "macro ethics" level focusses on the collective responsibility of the discipline and society. Additionally, adopting a framework, where ways of working are designed with relevant communities, requires understanding the perspectives of individuals, communities, and organizations. The aim of this study therefore was to assess the perceptions of education-focused Australian stakeholders. A survey collected the perspectives of 198 participants. The majority of participants (61.6%; n = 122/198) indicated that human fetal and embryological remains obtained prior to era of informed consent should be retained for use in education/research. It is likely that their perspective is based on the notion that if human fetal and embryological collections are used for good, then disposing of them would deny this benefit. Women (p < 0.001) indicated a preference for obtaining fetuses and embryos with informed consent for education and research (38.4%; n = 76/198). Majority were in favor of recording both maternal (MI) (59.6%; n = 118/198) and paternal information (PI) (58.1%; n = 115/198) with each donation. Majority (56.1%; n = 111/198) expressed that donations should be accepted from both parental sources. Consideration of stakeholder perspectives is important in developing guidelines regarding these collections. The results from this study demonstrate a level of discomfort with respect to collections without informed consent, which should be considered at the macro ethical and micro ethical level.

Comparing Walker's (2008) skull trait sex estimation standard to proteomic sex estimation for a group of South Asian individuals

This research assesses the potential for misidentification of sex in individuals of South Asian ancestry using the Walker (2008) morphological skull sex estimation standard [1]. Chromosomal sex was assessed using proteomic analysis targeting sex chromosome-specific amylogenic peptides. Results showed that the Walker method produced incorrect classification for 36.7 % of individuals. Overwhelmingly, those incorrectly assigned were chromosomally male. Misidentification was due to males within the group having lower trait scores (i.e., more gracile traits) than the standard would predict. There was also a high level of overlap in trait scores between male and females indicating reduced expression of sexual dimorphism. The use of established multivariate statistical techniques improved accuracy of sex estimation in some cases, but larger osteological data sets from South Asian individuals are required to develop population-specific standards. We suggest that peptide analysis may provide a useful tool for the forensic anthropologist when assessing sex in populations without population specific osteological standards.
