Resumo: | The aim of the present study was to evaluate the mechanical behaviour of the femur and humerus of Cerdocyon thous through three-point bending and axial compression tests. For this, 13 femurs and 15 humerus were used in the bending test, and 14 femurs and 15 humerus in the compression test; after the assays were completed, bone fragments were collected for evaluation by means of conventional optical and polarized light microscopy, and scanning electron microscopy. It was observed that the humerus is more resistant in relation to the femur in both tests, and that bone length and weight, in addition to the width of the diaphysis, are influential on the mechanical behaviour. Microscopic evaluation showed that, on the cranial surface of the fractured bones under flexion, the fracture was caused by the deflection mechanism, while the caudal surface was ruptured by delamination. In bones submitted to axial compression, diaphyseal fractures occurred by deflection, while physeal fractures were caused by several mechanisms. There was no significant correlation between the arrangement of collagen fibres or mineral content on the mechanical properties obtained in both assays. It can be concluded that there are significant differences in the mechanical behaviour of the femur and humerus of C. thous, where the humerus is more resistant than the femur in both flexion and compression loads. Such data allow us to predict the bone mechanical behaviour of C. thous in the face of trauma caused by flexion and compression impacts, such as those resulting from running over. |

Para ello se utilizaron 13 fémures y 15 húmeros en la prueba de flexión, y 14 fémures y 15 húmeros en la prueba de compresión; una vez finalizadas las pruebas, se recogieron fragmentos óseos para su evaluación mediante microscopía óptica convencional y de luz polarizada, y microscopía electrónica de barrido. Se observó que el húmero es más resistente en relación al fémur en ambas pruebas, y que la longitud y el peso del hueso, además del ancho de la diáfisis, influyen en el comportamiento mecánico. La evaluación microscópica mostró que, en la superficie craneal de los huesos fracturados bajo flexión, la fractura fue causada por el mecanismo de desviación, mientras que la superficie caudal se rompió por delaminación. En huesos sometidos a compresión axial, las fracturas diafisarias ocurrieron por deflexión, mientras que las fracturas fisarias fueron causadas por varios mecanismos. No hubo correlación significativa entre la disposición de las fibras de colágeno o el contenido de minerales sobre las propiedades mecánicas obtenidas en ambos ensayos. Se puede concluir que existen diferencias significativas en el comportamiento mecánico del fémur y húmero de C. thous, donde el húmero es más resistente que el fémur tanto en cargas de flexión como de compresión. Dichos datos nos permiten predecir el comportamiento mecánico óseo de C. thous ante traumatismos por impactos de flexión y compresión, como los resultantes del pisoteo.O presente estudo foi conduzido com objetivo de avaliar o comportamento mecânico do fêmur e úmero de Cerdocyon thous por meio dos ensaios de flexão em três pontos e compressão axial. Para tal, foram utilizados 13 fêmures e 15 úmeros no ensaio de flexão, e 14 fêmures e 15 úmeros no ensaio de compressão; finalizados os ensaios, foram coletados fragmentos ósseos para avaliação por meio de microscopia ótica convecional e de luz polarizada, e microscopia eletrônica de varredura. Observou-se que o úmero é mais resistente em relação ao fêmur em ambos os ensaios, e que comprimento e peso ósseos, além da largura da diáfise são influentes sobre o comportamento mecânico. A avaliação microscópica mostrou que, na face cranial dos ossos fraturados sob flexão, a fratura foi causada pelo mecanismo de deflexão, enquanto a face caudal se rompeu por delaminação. Nos ossos submetidos à compressão axial, as fraturas diafisárias ocorreram por deflexão, enquanto as fisárias foram originadas por diversos mecanismos. Não houve correlação significativa entre a disposição das fibras colágenas ou conteúdo mineral sobre as propriedades mecânicas obtidas em ambos os ensaios. Pode-se concluir que existem diferenças significativas no comportamento mecânico do fêmur e úmero de C. thous, onde o úmero é mais resistente que o fêmur tanto nas cargas de flexão quanto nas de compressão. Tais dados permitem prever o comportamento mecânico ósseo de C. thous frente a traumas causados por impactos de flexão e compressão, como aqueles resultantes de atropelmentos.Research, Society and Development2022-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2814410.33448/rsd-v11i5.28144Research, Society and Development; Vol. 11 No. 5; e34511528144Research, Society and Development; Vol. 11 Núm. 5; e34511528144Research, Society and Development; v. 11 n. 5; e345115281442525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/28144/24631Copyright (c) 2022 Felipe Martins Pastor; Gabriela de Oliveira Resende; Rejane Costa Alves; Louisiane de Carvalho Nunes; Guilherme Galhardo Franco; Jankerle Neves Boeloni; Rogéria Serakides; Maria Aparecida da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPastor, Felipe MartinsResende, Gabriela de OliveiraAlves, Rejane CostaNunes, Louisiane de CarvalhoFranco, Guilherme Galhardo Boeloni, Jankerle NevesSerakides, RogériaSilva, Maria Aparecida da 2022-04-17T18:18:56Zoai:ojs.pkp.sfu.ca:article/28144Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:45:38.988738Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
