RESUMO
Objetivou-se avaliar as implicações e os resultados obtidos frente aos tratamentos conservativo e cirúrgico em
37 cães sem distinção de sexo, raça ou idade, que apresentaram fraturas e luxações vertebrais (FLV)
toracolombares. Cada paciente passou por anamnese, seguida por exames clínico, neurológico e radiográficos
para se obter o diagnóstico neuroanatômico e a severidade da lesão. Os cães foram submetidos ao tratamento
conservativo ou cirúrgico de acordo com as características de cada caso. Dos 37 animais deste estudo, 37,7%
tinham percepção de dor profunda (PDP) intacta. Vinte animais foram submetidos ao tratamento conservativo,
14 ao tratamento cirúrgico e três animais faleceram antes do tratamento. Dos animais que mantiveram a PDP
intacta, a taxa de recuperação foi de 100%, com tempo de recuperação total variando de sete a 75 dias, ao passo
que, dos animais que perderam a PDP, nenhum recuperou a deambulação voluntária. Dos 14 animais operados,
42,8% apresentaram alterações vertebrais não visibilizadas ao exame radiográfico convencional, sendo
necessária mudança na técnica cirúrgica planejada em 14,2% desses casos. Nos animais que mantiveram a
PDP, não houve diferença significante nas taxas nem no tempo de recuperação da deambulação voluntária,
independentemente do tipo de tratamento. Entretanto, houve diferença altamente significante entre os graus que
mantiveram a PDP intacta com os animais que perderam a percepção de dor profunda em relação à taxa de
recuperação. A taxa de eutanásia foi menor que em outros trabalhos descritos na literatura. Dos animais sem
PDP submetidos ao tratamento conservativo ou cirúrgico, 31,25% readquiriram a capacidade de caminhar sem
recuperar a PDP, sendo essa deambulação involuntária atribuída ao caminhar espinal.
ABSTRACT
Our aim of was to study the implications and results associated with conservative and surgical
treatment of dogs with thoracolumbar Vertebral fractures and luxations (VFL) so that the information obtained
can be used to obtain guidelines that lead to greater recovery rates. For such, 37 dogs presenting VFL were
examined, without distinction of sex, breed, or age. Each patient had detailed history obtained, followed by
clinical, neurologic and radiographic exams for obtaining neuroanatomic location and severity of the nervous
and vertebral lesions. The dogs were submitted to conservative or surgical treatment according to each case.
Deep pain perception (DPP) was intact in 37.7% of the 37 dogs in this study. Twenty dogs received
conservative treatment, 14 underwent surgery and three dogs died before treatment. Of the dogs with intact
DPP, 100% recovered, with a recovery time varying between seven and 75 days, while none of the dogs that
lost DPP recovered voluntary motion. Of the 14 dogs submitted to surgery, 42.8% had vertebral lesions that
weren't detected using conventional radiography, which demonstrates the low sensitivity of this exam, and led
to a need for a change in the planned surgical technique in 14.2% of these cases. In dogs with intact DPP there
was no significant difference in time or rate of recovery of voluntary motion, regardless of the treatment
method. However, there was a highly significant difference between the dogs which retained and lost DPP
regarding recovery rates. The percentage of euthanasia was less than in other reports, probably due to the
greater awareness and protectiveness of owners nowadays. Of the dogs without DPP treated either surgically or conservatively, 31.25% recovered ambulation without recovery of DPP, characterizing this ambulation as
involuntary, attributed to spinal walking
