The investigation object: physical development the children of the first childhood period. The investigation goal: to study the morfofunktsional features of physical development the children period of the first childhood period constantly resident in town Lugansk, and to expose their connection with violation of carriage or deformation deformation of the columna vertebralis. Methods of research: Morphological (descriptive, comparative, anthropometric, morfometric); ultrasonic; x-ray; statistical. Theoretical and practical value of the obtained results. Morfometric descriptions of physical development of children of the first childhood period are set. Basic ultrasonic points of counting out of vertebrae is certain in a norm and at appearance of deformation. It is offered for the exposure of deformation of vertebral post for children and dynamic supervision at the correction of compensate changes in the structural elements of vertebral post to apply the methods of uninvasions of research – ultrasonic by which it is possible to estimate the state of motive segment of vertebral post and to find out the initial displays of torsiya vertebrae. Results which were reached can be used in research work, practical health protection and in a pedagogical process. Scientific novelty of the obtained results: The morfofunktsional features of physical development of children of period of the first childhood are first studied, constantly resident in Lugansk, and their connection with the degree of deformation of vertebral post and in comparison with physical development of children of the beginning of the ХХ century. It is set that in connection with intensive growth of children of period of the first childhood there is a risk of development of changes in a vertebral post - violation of carriage or deformation of vertebral post. In addition, it is set that children of period of the first childhood began ХХI century had indexes of morfometric higher, than children began ХХ century. It is set that the level of physical development is rendered by influence on forming of deformation of vertebral post of І degrees and violations of carriage for children depending on a floor and age. It is set, that for the children of the first childhood period the high-quality indexes of physical development depends on the longitudinal sizes of body (length of body, absolute height of head, lengths of free extremities and their links – shoulder, forearm, brush, thigh, shin, foot), and growth of length of body is mainly carried out thanks to growth of free lower extremities, that in this age group enables to trace constitutional types (brachi-, mezo- and dolichomorphic). It is set, that the proportions of transversal and longitudinal diameters of head change in the process of child’s growth. It is certain, that intensive growth of children of in period of the first childhood reduces compensate-adaptation possibilities of the bone-muscles system and is the starting moment of development violation of carriage and deformation of vertebral column I degrees. For children with deformation of vertebral column II degree morphometric indexes were not high, that is explained by the other etiology and by the development of deformation of vertebral column in earlier age. It is set that indexes of ultrasonic diagnostics of vertebral post, separate vertebrae and intervertebralis discusis correspond given morphological and x-ray researches. For the children of period of the first childhood began ХХI century, multiplying all longitudinal sizes and mass of body, circumferences of thorax is exposed, and also as compared to the indexes of children of this age group began the change of their correlations of ХХ century. For children ХХI century began the exposed features of growth processes conduce to the asthenic constitution and are negative, to what plenty of pathology of vertebral post testifies in this age group. The degree of implementation: The basic results of research are inculcated in an educational process on the departments of anatomy of man Kharkov national and Lugansk state medical universities, to the department of anatomy, physiology of man and animals of the Lugansk national university the name of T.Shevchenko, to the department of paediatrics of faculty of the in-plant training of doctors of the Lugansk state medical university, to the department of operative surgery with the topographical anatomy of the Crimean state medical university the name of S.I.Georgievskiy, and also in work of the Lugansk regional child's hospital, Lugansk regional medical-athletic dispensary and company of «Medakom».
