X-ray anatomical parameters of the skeletal skeleton of the motor apparatus in the assessment of species and intraspecific identification of animals

The improvement of classical and the development of new methods for diagnosing the condition of the skeletal skeleton of the musculoskeletal system remains one of the urgent problems in the field of clinical anatomy, which is of applied importance for veterinary medicine and veterinary and sanitary expertise. At the same time, when assessing the state of the musculoskeletal system, the parameters of the anatomical norm and its variants are not always taken into account, which simulates numerous diagnostic errors. One of the objective and accessible methods of radiological diagnosis of the state of the osteoarticular system is an overview radiography, which provides objective information about the morphological features of the mineral phase of the bone substance. The article presents X-ray anatomical parameters of the bone skeleton of the thoracic and pelvic limbs of animals of various taxonomic groups. The research was performed at the A. F. Klimov Department of Animal Anatomy and Histology of the Moscow State Academy of Veterinary Medicine and Biotechnology – MBA named after K. I. Scriabin. The methodological approach used included conventional and fine anatomical dissection, X-ray imaging, radiometry with subsequent determination of bone development indices, comparative X-ray anatomical analysis and statistical processing of the obtained digital data. The aim of the study was to develop an algorithm for X–ray anatomical assessment of the state of the osteoarticular system in animals of various taxonomic groups. X-ray anatomical parameters of the condition of the bone skeleton of the extremities have been established. Along with the general patterns of the anatomical structure, species-specific features have been identified, which are not only an indicator of the norm of the structure, but also its variant, which is extremely important to take into account when deciphering radiographic information. The data obtained can be basic in comparative and clinical anatomy of animals, in identifying pathologies of their musculoskeletal system, as well as in matters of forensic veterinary examination.
