“…Compressive myelopathies are uncommon in ruminants and are associated with spaceoccupying lesions in the spinal canal, such as abscesses, granulomas, traumas, malformations and neoplasms (Sherman and Ames, 1986;Borges et al, 2003;Ubiali et al, 2011;Panziera et al, 2014;Panziera et al, 2016). Traumas and vertebral abscesses are more frequent in beef cattle, while neoplasms, mainly lymphomas, are seen, more commonly, in adult dairy cows (Sherman and Ames, 1986;Jacobs et al, 2002).…”

Cases of compressive myelopathy syndrome associated with post vaccinal pyogranulomas were diagnosed post mortem in three cows from a farm in Minas Gerais state, Brazil. These cows presented ataxia and bilateral paresis of the pelvic limbs, which evolved to paralysis, and sternal recumbence. On necropsy, locally extensive areas of the longissimus dorsi muscle were replaced by pyogranulomas supported by moderate amounts of fibrous connective tissue. On the cut surface, some nodules contained yellowish and viscous fluid (purulent exudate) or whitish fluid (interpreted as the oily adjuvant of a vaccine). In the spinal canal of the subjacent vertebrae, compressing the spinal cord, were pyogranulomas identical to those described in the skeletal muscle. Histologically, the pyogranulomas were composed of a central clear vacuole (consistent with the space left by the oil adjuvant droplets), surrounded by neutrophils and, more externally, by large numbers of epithelioid macrophages and fewer multinucleated giant cells. In the white matter of the spinal cord were numerous well-defined, clear vacuoles (Wallerian degeneration). The association of the clinical history and pathological findings allowed the diagnosis of compressive myelopathy associated with pyogranulomatous reaction to the oily adjuvant of the foot-and-mouth disease vaccine, in this case, due to its inadequate application.

“…Algumas condições de manejo podem predispor à ocorrência de fraturas vertebrais. A égua em questão era extremamente agitada, segundo o proprietário; uma doma racional e manejos adequados, portanto, poderiam ter evitado o acidente aqui descrito (Borges et al, 2003).…”

“…Quando presentes, a tomografia computadorizada (CT) e a ressonância magnética (MRI) podem auxiliar na identificação de lesões envolvendo diretamente a medula espinhal (Biervliet et al, 2004). É importante que as fraturas vertebrais sejam incluídas na lista de diagnóstico diferencial em animais em decúbito permanente (Borges et al, 2003).…”

 RESUMOAs lesões vertebrais cervicais são relativamente comuns nos equinos. No entanto, são poucas as descrições a respeito desse tema na literatura. Acredita-se que esse fato se deva, em parte, às limitações relacionadas ao diagnóstico. Em virtude de um traumatismo cervical, o animal pode apresentar sinais clínicos de paresia e paraplegia até tetraparesia ou tetraplegia, que podem culminar em estado comatoso e, eventualmente, em morte. Esses sinais clínicos podem ser detectados no exame físico, porém, quando associado à imaginologia (avaliação radiográfica), permite a obtenção de diagnóstico mais preciso da lesão. Consequentemente, um prognóstico mais adequado pode ser estabelecido para o paciente. Em face do exposto, apresenta-se o caso de uma égua Mangalarga, de quatro anos de idade, com sinais de tetraplegia pós-trauma, aumento de tônus muscular e paralisia espástica, com hiperreflexia, nos quatros membros. Por meio dos exames neurológicos realizados na paciente, em associação com as imagens radiográficas convencionais e contrastadas, foi possível estabelecer o diagnóstico do quadro. O animal apresentava lesões envolvendo as duas primeiras vértebras cervicais, atlas (C 1 ) e áxis (C 2 ), e a quinta e a sexta vértebra (C 5 -C 6 ), destacando fratura de C 1 , deslocamento do dente de C 2 e subluxação entre C 5 e C 6 , com compressão ventrodorsal da medula espinhal. Confirmadas as suspeitas neurológicas e mediante prognóstico desfavorável, o animal foi submetido à eutanásia, com consentimento do proprietário. As lesões observadas nas imagens radiográficas foram confrontadas e confirmadas na necropsia.Palavras-chave: cavalo, compressão medular, fratura, imaginologia, pescoço ABSTRACT Cervical vertebral lesions are relatively common in equine patients

“…Os sinais clínicos de animais traumatizados apresentam início agudo e variam de acordo com a localização e a gravidade da lesão da medula espinhal [12,13,15]. As alterações neurológicas de lesões cervicais variam de dor a tetraplegia [4,7]. O valor econômico e genético do animal, a localização e o tipo de fratura, o custo dos procedimentos e o prognóstico determinam a viabilidade da realização do tratamento de fraturas em grandes animais [1,4,12,14].…”

Background: Trauma is the main cause of spinal fractures and dislocations in humans and large animals. Clinical signs present with acute onset and vary according to the location and severity of the spinal cord injury. The treatment of fractures in large animals depends on economic value, cost of procedures, prognosis, location and type of fracture. However, although spinal fractures in large animals are not uncommon, the literature about their clinical aspects and treatment is scanty. Therefore, the purpose of this report is to describe a surgical stabilization of atlantoaxial subluxation, fracture of the third cervical vertebra and C2-C3 subluxation.Case: An approximately 2-year-old Île-de-France sheep, weighing 101 kg, with a history of cervical trauma and non-ambulatory tetraparesis was treated at the Veterinary Hospital of the Institution (UNIPAMPA). During physical examination, the animal presented good general physical condition and heart rate, respiratory rate and temperature was according to physiological parameters for the species. The animal remained in lateral decubitus, with minimal head and limb movements, and exhibited deep pain sensitivity. Clinical treatment with dexamethasone, limb physiotherapy and change in lateral decubitus position were employed, but failed to improve the animal’s condition. After five days of unresponsive to clinical treatment, the patient was referred to the neurology department, where it underwent neurological examination and radiographic examination of the cervical region was performed under general anesthesia. The radiographic examination revealed atlantoaxial subluxation, by displacement of the odontoid process into the vertebral canal, fracture of the third cervical vertebra and C2-C3 vertebral subluxation. The surgical planning aimed cervical vertebral instability repair using atlantoaxial arthrodesis associated the stabilization of C1-C2 and C2-C3 vertebrae with Schanz pins and bone cement, due facility and versatility this association. The postoperative radiographic examination showed incomplete insertion of the Schanz pin into the left Atlas wing and a cervical collar was recommended. The clinical evaluation was performed daily, and after 23 days of surgery the animal could crawl in lateral decubitus besides assisted walking ability. However, the animal died 36 days after surgery due to severe dyspnea. A necropsy revealed pulmonary edema and hepatic lipidosis, besides hepatic septic thrombus. Moreover, the vertebral canal of C1-C2 and C2-C3 segments stayed realigned and stabilized, without spinal cord injury and trachea compression.Discussion: Non-ambulatory tetraparesis, and minimal head and limb movements confirm severe spinal cord injury. The failure of clinical treatment, craniocervical instability in C1-C2 and C2-C3 and the high economic and genetic value of patients was definite for the surgical indication, besides reserved prognosis. The surgical treatment aim is recovery motor function from spinal cord decompression, vertebral canal realignment and the stabilization of vertebral instability. The cervical collar was placed on the patient after the surgery was intended to prevent rotation of the atlantoaxial joint, aiding vertebral stability. It is believed that the recovery of large animals with spinal cord injuries like in this case report is slower due to their heavy weight and the difficulty in managing such patients. This case report confirms that the techniques employed here achieved the proposed objectives of spinal canal alignment and spinal stabilization, showing improvement of clinical signs and recovery of the animal’s limb and neck movements.
