Resumo: Finite element models aid in understanding dynamic processes in the study of diseases and treatments. Cervical spondylomyelopathy (CSM), also called wobbler syndrome, is a disease that affects mainly large- and giant-breed dogs, and seems to have a static and dynamic component in its pathophysiology. The present objective was to create a finite element model representing the C2-C7 segment of the vertebral column of a Great Dane dog without abnormalities, as well as the adaptation of this model to represent a dorsal laminectomy and a hemilaminectomy at C5-C6. This is expected to contribute to the investigation of the biomechanical component of CSM, as well as allow a comparison of the various surgical methods proposed for treatment of this syndrome. A 2-year-old Great Dane dog without neurologic or imaging changes in the cervical region of the vertebral column was selected. Computed tomography images from this dog were processed to construct a finite element model representing vertebrae, intervertebral discs, and ligaments. Material properties were adapted from the literature. Range of motion of the model under 2Nm for flexion, extension, axial rotation, and lateral bending were compared with literature. Range of motion was observed to be lesser than cited for cadavers of a different breed. This difference could be considered as resulting from differences between breeds and the use of human material properties. When comparing the intact model with the modified laminectomy and hemilaminectomy models, an influence of the hemilaminectomy was observed in range of motion, especially in axial rotation to the side opposite the simulated procedure. Construction of these models would be the first step to applying finite element analysis to the study of CSM in Great Danes.

Espondilomielopatia cervical (EMC), também chamada de síndrome de wobbler, é uma doença que afeta principalmente cães de raças grandes e gigantes, e que parece ter um componente estático e dinâmico na sua fisiopatogenia. Objetivou-se criar um modelo de elementos finitos representando o segmento de C2 a C7 da coluna vertebral de um dogue alemão sem alterações, assim como adaptar esse modelo para representar uma laminectomia dorsal e hemilaminectomia em C5-C6. Espera-se com isso contribuir para a investigação do componente biomecânico da EMC, além de permitir a comparação dos diversos métodos cirúrgicos propostos para o tratamento dessa síndrome. Foi selecionado um cão de 2 anos de idade, da raça Dogue alemão, sem alterações neurológicas ou de imagem na região cervical da coluna vertebral. Imagens de tomografia computadorizada deste cão foram processadas para construir um modelo de elementos finitos representando as vértebras, discos intervertebrais e ligamentos. As propriedades materiais foram adaptadas da literatura. A amplitude de movimento do modelo sob 2Nm para flexão, extensão, rotação axial e flexão lateral foram comparadas com a literatura. Observou-se que a amplitude de movimento do modelo foi menor do que a citada para cadáveres de outra raça. Considera-se que essa diferença possa advir de diferenças entre raças e do uso de propriedades materiais adaptadas de humanos. Ao comparar o modelo intacto com os modificados com laminectomia e hemilaminectomia, observou-se que houve influência da hemilaminectomia na amplitude de movimento, principalmente na rotação axial contralateral ao procedimento simulado. A construção desses modelos seria o primeiro passo para aplicar o uso do método de elementos finitos para o estudo da espondilomielopatia cervical em Dogues alemães.Submitted by Mario BC (mario@bc.ufrpe.br) on 2018-02-22T12:56:00Z No. of bitstreams: 1 Marilia de Albuquerque Bonelli.pdf: 1903907 bytes, checksum: 8de429c7dc9abc6c230fc38f56331819 (MD5)Made available in DSpace on 2018-02-22T12:56:00Z (GMT).
