The study of the structure of morbidity or individual nosological groups of diseases involves not only establishing the degree of their prevalence, but also, depending on the methodology of such studies, makes it possible to identify the prevailing clinical and morphological forms, the objectivity of diagnostic algorithms and the effectiveness of therapeutic measures, which makes it possible to assess the state of the solution or another clinical problem, adjust the ways to solve it and improve clinical management and form directions for improving the market for therapeutic agents. The aim of the work was to establish the structure of the types of different clinical and radiological forms of comminuted bone fractures in dogs according to the principles of the international classification AO/ASIF. We performed a clinical and radiological assessment of comminuted fractures of long bones in dogs (n=24) with spontaneous bone injuries admitted to the Interdepartmental Small Animal Clinic of Belotserkovsky NAU, in which 26 comminuted fractures were diagnosed. The main forcing ship fractures were car accidents - 58.4%, alarming world causas unverified creatures of bloodshed - 20.8%, injuries caused by other creatures - 12.5% and 8.3% - falling from height. According to thestate factor, the removal from white grains is 70.8%, and in 62.5% - animal with weight of 11 kg, and in 54.2% - dogs of different breeds, while 45.8% were outbred. Comminuted fractures according to morphosegmental localization were: diaphyseal - 46.2%, metaphyseal - 42.3%, epiphyseal 11.5%. According to the principles of the international classification AO / ASIF, their largest share - 50%, belongs to type C, 46.2% - to type B and the smallest - 3.8%, to the simplest type A. Within the subgroups of the largest - 19.2 %, the proportion for subgroups B1, B2 and C2 turned out to be slightly less - 15.4% for C1 and C3 and very small - 7.8% and 3.8% for B3 and A2, respectively. Consequently, the morphosegmental localization of the typification of the type and complexity of fractures according to the principles of the AO/ASIF classification provides more detailed information, which creates the basis for the proposed choice of the most rational methods and means of osteosynthesis. Key words: osteosynthesis, reparative osteogenesis, femur, tibia, radius, ulna, humerus.
