Osteology and radiology of the vertebral column in the white‐eared opossum (Didelphis albiventris)

Abstract: The white‐eared opossum present a higher roadkill number in Brazil, and the vertebral column is often affected when some type of trauma occurs. Thus, this study describes the osteology and radiology of the vertebral column in white‐eared opossum to serve as a basis for support in the veterinary clinical care, since the casuistry of care of this marsupial has increased every year. Radiographs of the cervical (C), thoracic (T), lumbar (L), sacral (S) and caudal (Cd) segments of the vertebral column were taken in… Show more

“…The white-eared opossum ( Didelphis albiventris ) presents three different vertebrae formulas, C7/T13/L6/S2 is the usual formula, and the lumbar vertebrae count could vary between L5, L6, and L7. This finding suggests that the Didelphis genus could present variations in the vertebral formula; nevertheless, lumbosacral plexus has not been reported in this species, and the variations in the lumbar nerve’s origin and distribution are unknown [ 13 ].…”

“…Os poucos trabalhos mais enfocados em morfologia desta espécie dedicamse ao estudo de vísceras, como a pesquisa de Schäfer, Filho e Watanabe (2017) sobre a estrutura da língua deste animal. Os estudos de Schimming et al (2016), Inamassu et al, (2017 e Inamassu et al, (2020) trazem descrições osteológicas para D. albiventris, porém não abordam a musculatura, ou mesmo a descrição completa do esqueleto. Desse modo, percebe-se a importância científica do estudo desta espécie, a qual demonstra um reduzido volume de dados acerca da morfologia do aparelho locomotor de forma integrada deste animal.…”

“…Os elementos anatômicos das vértebras bicúspides, tricúspides e unicúspide são semelhantes ao descrito para outros mamíferos eutérios, como o cão doméstico. Os processos espinhosos das vértebras bicúspides são característicos (INAMASSU et al, 2020), bem como a porção cranial sutil do ligamento nucal. A presença de um canal transverso pode indicar a presença de vasos vertebrais como fonte de irrigação/drenagem encefálica.…”
