Thus, this study describes the osteology and radiology of the vertebral column in white\u2010eared 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 thirty\u2010five white\u2010eared opossums (<jats:italic>Didelphis albiventris<\/jats:italic>). Furthermore, ten opossums without evident vertebral acquired or congenital abnormalities at the radiographic study were selected for anatomical study. Osteology was correlated with the radiographic images. The use of radiographs allowed the identification of congenital and acquired vertebral changes, as well as the identification of anatomical structures, their distribution and morphology and the number of vertebrae. The vertebral formula varied in the white\u2010eared opossum. In 27 of 35 white\u2010eared opossums (77.2%) with normal vertebral morphology, three vertebral formulas were observed: C7\/T13\/L6\/S2 (62.9%), C7\/T13\/L5\/S2 (5.7%) and C7\/T13\/L7\/S2 (8.6%). Most of the specimens presented 27 caudal vertebrae. The anticlinal vertebra was identified as T10 in 77.2% and T11 in 22.8% of opossums. Cervical block vertebra was observed in two animals and sacrocaudal block vertebra in one animal. The haemal arches could be seen from Cd3\u2013Cd4 in 80% and Cd2\u2013Cd3 in 20% of opossums. The white\u2010eared opossum showed a slender vertebral column with a relatively short thoracic region, a relatively long lumbar region and a highly flexible lumbosacral transition, suggesting that this animal is a fast\u2010running and agile opossum. Therefore, these findings may serve as a basis for further research and support the veterinary clinical care, since the casuistry of care for this marsupial has increased every year.<\/jats:p>","DOI":"10.1111\/ahe.12610","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T21:55:12Z","timestamp":1598651712000},"page":"128-135","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Osteology and radiology of the vertebral column in the white\u2010eared opossum (<i>Didelphis albiventris<\/i>)"],"prefix":"10.1111","volume":"50","author":[{"given":"Let\u00edcia Rocha","family":"Inamassu","sequence":"first","affiliation":[{"name":"School of Veterinary Medicine and Animal Science Graduate Program in Wild Animals S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0837-9612","authenticated-orcid":false,"given":"Bruno Cesar","family":"Schimming","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science Graduate Program in Wild Animals S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"},{"name":"Department of Anatomy Institute of Biosciences S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmel Rezende","family":"Dadalto","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Veterinary Radiology School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Jaqueline","family":"Mamprim","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine and Animal Science Graduate Program in Wild Animals S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"},{"name":"Department of Animal Reproduction and Veterinary Radiology School of Veterinary Medicine and Animal Science S\u00e3o Paulo State University (UNESP)  Botucatu Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,28]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"76","article-title":"A review of bone preparation techniques for anatomical studies","volume":"3","author":"Ajayi A.","year":"2016","journal-title":"Malaya Journal of Biosciences"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmor.10062"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511541889"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2008.01492.x"},{"key":"e_1_2_8_6_1","volume-title":"Os marsupiais do Brasil: Biologia, ecologia e conserva\u00e7\u00e3o","author":"C\u00e1ceres N.
