Background. The neck, its bone-cartilaginous and muscle apparatus, etc. high activity is well known. Cervical spine degenerative-dystrophic processes are considered to be an urgent problem. The purpose of the study was to determine the clinical and morphometric changes of the cervical spine in humans and animals with neck pain based on a clinical and neurological examination, determination of the vertebral body density, their configuration, and ratio for timely correction and prognosis of this patho­logy. Materials and methods. Pain intensity was studied in humans and animals using the adapted visual-analogue scale. The inde­xes of computer tomography with measurement of vertebral body density, and morphometric indexes with an emphasis on C5-C7 le­vel were also studied. All studies were conducted following existing bioethical standards. Results. The pathology of spine configuration was registered in 84.6 % of the examined patients in the form of angular kyphosis or straightened lordosis, more often in women. It was observed in 34.7 % of cases in dogs and cats. The normal configuration is more common: in cats — 78.6 % and in dogs of small breeds — 78.5 %, in large breed dogs — only 26.3 %, and deformations were more frequent than in cats and small dogs (2.7 times more). The cervical vertebrae bodies density in all groups decreased toward the caudal direction with a difference of 18.1 % in humans. In cats — 2.7 %, in dogs of small breeds, it was higher (7.5 %), and in large breed dogs, it reached 14.3 %. The maximum deviations of the studied indicators were found in humans and maximally coincided with those in dogs of large breeds. Conclusions. Thus, animals, especially dogs of large breeds, can serve as a model for studying etiopathogenetic factors, the course, prognosis of degeneration of the bone-cartilage apparatus.
