The altered profile of a donated cadaver population: challenges for teaching and research?

ABSTRACT

Efforts by anatomists over the recent past, have converted the cadaver population in a South African institution from a predominantly unclaimed population into one purely derived from donors. Concurrent with this transformation were noticeable changes in cadaver demographics, which raised concerns for aspects of teaching and research. The aim of this study was therefore to explore the effects of donation on the demographics and anatomical integrity of the School's 2017 cadaver population. The provenance, ancestry, sex and age of 74 cadavers were investigated. Dissected cadavers were studied to ascertain the general condition of their anatomy. Variations in tissue integrity, morphology and overt pathologies were surveyed. Cadavers represented only one population group with slightly more females (54%). The majority of the cohort (62%) was aged between 71 and 90 years. With regards to anatomical integrity, 60% of the cadavers presented with adhering fascia, but no significant differences in the quantity of fat were found across the sample. High levels of muscle tearing and atrophy (76%) occurred and variations in visceral anatomy were noted. Various surgical interventions and overt pathologies were also observed. The donated cadaver population differed from previous unclaimed cadaver populations in that they consisted of only White, older individuals. Variations, surgical interventions and pathologies offer staff in anatomy an opportunity to engage with more clinically-oriented teaching, as well as introducing students to the discipline of gerontology
