American Association for Anatomy recommendations for the management of legacy anatomical collections. Anat Rec (Hoboken) 2024; 307:2787-2815.

Abstract
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.

Abstract
INTRODUCTION Intramedullary nailing is the surgical method of choice for the treatment of proximal femur or femoral shaft fractures. Implant manufacturers aim to design implants fitting for the broadest possible population segment. As complete morphological data sets of long bones are not widely available, anatomical collections of historical dry bone specimens may represent abundant additional sources of morphological three-dimensional (3D) data for implant design, provided they are consistent with present populations. This study aims to investigate secular trends and age-related changes of femoral morphology of the Caucasian population over the past 800 years. MATERIALS AND METHODS Computer graphical measurements of 3D-datasets of right and left femora derived from computed tomography (CT) scans, representative of the present Caucasian population, were compared to computer graphical measurements of 3D-datasets of right and left femora derived from CT scans of specimens from a historical medieval European bone collection. RESULTS Clinically relevant parameters of historical medieval European femora were found mostly consistent with correlative data of the present Caucasian population. Additionally, for some of the evaluated parameters, particularly anteversion, morphological differences significantly correlated to individual age and sex could be identified, whereas other parameters such as caput-collum-diaphyseal angle or radius of anterior femoral bowing were not correlated to individual age or sex. CONCLUSION The findings suggest that more recent historical specimen collections may be a convenient and easily accessible source of new 3D morphological data, as well as to complement existing data, to be used by researchers and manufacturers for the development of intramedullary femoral nails.

Fourniquet SE, Beiter KJ, Mussell JC. Ethical Rationales and Guidelines for the Continued Use of Archival Collections of Embryonic and Fetal Specimens. ANATOMICAL SCIENCES EDUCATION 2019; 12:407-416. [PMID: 31127982 DOI: 10.1002/ase.1897] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 05/19/2019] [Accepted: 05/21/2019] [Indexed: 06/09/2023]
Abstract
Benefits from the use of cadavers in anatomical education are well described. Historically, human embryos and fetal cadavers were used in anatomy education to understand development and congenital malformations. Recently, three-dimensional printed models produced from archival fetal specimens, and online repositories of images from archival collections of embryos and fetuses, have been used as an educational tool in human development courses. Given that the archival specimens were likely obtained prior to the era of informed consent, this raises questions about their appropriate and ethical use. Because some institutions in the United States retain archival collections of embryonic and fetal specimens that were once used as educational tools, their existence and utility require frequent reexamination against contemporary ethical frameworks to guide appropriate use or utilization. Four ethical rationales for uses of these collections are examined, including destruction, indefinite storage, use in research, and use in health professions education. Guidelines for the use of archival collections of human embryos and fetuses are presented. Indefinite storage and use in health professions education are supported, while use in research is also permitted, however, such use is limited and dependent on circumstance and purpose. The development of current digital repositories and three-dimensionally printed models based on archival collections that were collected without informed consent, or those promoting commercial opportunity, are not supported. New embryonic and fetal donations obtained with informed consent should include reference to potential uses with new technology and virtual, genetic, or imaging applications.

Abstract
The Mawangdui tomb No.1 cadaver, a female corpse from the Western Han Dynasty, was unearthed in 1972. Forensic examination at the time of discovery indicated fairly remarkable presence of bodily constituents at the anatomical, histological, and molecular levels. The cadaver was preserved in a formalin-based fixative afterward, and maintained in the Hunan Museum. To better protect this rare human corpse, a reappraisal of the status of preservation was carried out using noninvasive approaches, including X-ray radiography, gross anatomical examination, and histological, microbiological, and molecular analyses of sampled tissues. The cadaver remained essentially intact from a gross anatomical perspective, with radiography of the skeletal system and arterial contrast filling appeared comparable with the original documentation. The light microscopic features of the skin, cartilage, and skeletal muscle remained detectable, as were the stratified ultrastructure of the collagen and muscle fibers. The levels of nitrogen and amino acidic elements appeared elevated in the cadaver and liver preservation fixatives, with a higher calcium and phosphate concentration in the former. These findings suggest that there existed a certain degree of macromolecule degradation and bone decalcification in the cadaver, likely irrelevant to biological decomposition. The reappraisal also led to the implementation of stronger scientific measures to better protect the cadaver through a renovated Museum-University coadministrative management agreement.
