Abstract

Kyphotic deformity of the vertebral column is determined by a significant decrease in the ability to support the pelvic limbs, the presence of pain syndrome, and in severe cases, pelvic limb plegia in dogs. The diagnostic component of this disease and the prognosis of surgical intervention, as well as the postoperative course, require the search for an algorithm for controlling the development of the pathological process and performing operations.
The study was conducted in order to present a comparative characteristic of methods for measuring kyphotic deformity in the sagittal plane and is based on the observation and surgical treatment of 11 dogs of chondrodystrophic breeds for the period from 2017 to 2020 with a diagnosis of kyphosis of the thoracic spine. The following breeds were under observation: 4 pugs, 5 French bulldogs, 2 Boston terriers. All animals at the time of observation were aged from 9 months to 1,5 years. A comparative evaluation of the Cobb–Lipmann and Ferguson methods for dogs was performed. The analysis was carried out on the basis of the following data: breed, gender, age, body weight, duration of clinical signs until the moment of treatment at the clinic, the results of neurological examination at the initial consultation, the results of magnetic resonance imaging (MRI), computed tomography (CT) and radiography of the thoracic spine. As a result of the study, it was found that the average angles of kyphosis in animals with physiological kyphosis and the absence of neurological deficiency vary from 20 ° to 28 °. In the presence of pronounced deformity and manifestation of neurological deficit of varying degrees, the angle will be from 36 ° to 49 °.
