ABSTRACT
The relationships between linear dimensions of the lumbar intervertebral discs (IVDli-l2, IVDl2-l3, IVDl3-l4, IVDl4-ls) and somatometric parameters in girls and females of the first adulthood were investigated. The numerous relationships between the partial (height, sagittal and transverse sizes) linear dimensions and total sizes of the lumbar intervertebral discs in girls and women of the first adulthood (16-26 years) with their somatometric parameters were found. The linear dimensions of the lumbar intervertebral discs (height, sagittal and transverse sizes) were measured on the MRI images in the axial, sagittal and coronal plains. The arithmetic means of absolute correlation coefficients between particular and total individual sizes of IVDli-l2, IVDl2-l3, IVDl3-l4, IVDl4-l5 and relative quantity with somatometric parameters were calculated with following results: arithmetic means of absolute correlation coefficients for particular individual sizes are within 0,120 - 0,170; for total sizes - 0,190; for ratio of the total sizes to the mass-growth coefficient - 0,507.

Introduction. The use of the noninvasive analysis of morphological properties, normative absolute and relative linear intervertebral discs dimensions for interpretation of the radiological results can improve the evidentiary direction of preclinical spine pathology manifestations definition, facilitate differential diagnosis, dynamic clinical observation and treatment effectiveness [4,6,10]. The constitutional and anatomical variations, the spondylometric parameters particularity of the functional spinal unit elements form an important prerequisites of spine pathology origin [7]. The obtained results of interrelations between linear IVDs sizes with somatometric parameters for detection of spine pathology

are used. Nowadays one can find numerous studies concerning this scientific problem. However, researching correlations between partial linear dimensions and total sizes of IVDs with somatometric parameters of girls and women of the first adult age in Ukrainian studies are underrepresented.
The aim of research is to investigate the peculiarities of relationships between partial linear dimensions of the lumbar intervertebral discs (IVDl1-l2, IVDl2-l3, IVDl3-l4, IVDl4-l5) and their total sizes with somatometric parameters in girls and females of the first adulthood.
Materials and methods. The Bioethics Committee of the National Pirogov Memorial Medical University (Vinnytsya) didn't find in research materials anything contrary basic bioethical norms of the Helsinki Declaration, the Council of Europe Convention on Human Rights and Biomedicine (1977), the relevant provisions of the WHO and the laws of Ukraine.
Individual somatometric investigation was performed for each person. General (body length and body weight) and particular sizes (the longitudinal, the transverse and the circumference sizes, pelvic sizes and skinfolds thickness) according to the V. Bunak procedure were measured [1]. The bony, muscle and fat components of the body mass were estimated by the method of Matiegka J. [8] and the American Institute of Nutrition (AIN) [9]. The lumbar spine MRI in girls and women of the first adulthood (16-26 years) with the measuring of anterior-posterior diameter, frontal diameter and vertical size of the lumbar IVD was carried out. The anterior height, medial height and posterior height of the IVDs in sagittal plane of MRI of the lumbar spine data were measured. Average height (height) of each lumbar IVDs was calculated as an arithmetic mean of the IVDs height in front, central and back portions on midsagittal plane of lumbar MRI data [3,5]. The total IVD size of investigated girls and women of the first adulthood was calculated as a sum of anterior-posterior diameter, frontal diameter and vertical size for each lumbar IVD. The statistic analysis was performed by using the Pearson's correlation coefficient (r) in the licensed statistical software «Statistica for Windows 13» (StatSoft Inc., № JPZ804I382130ARCN10-J). To assess the strength of the correlation, the Robert Chaddock system [2] was used.

Analysis of the arithmetic means of absolute correlation coefficients between particular sizes, total sizes of IVDl1-l2, IVDl2-l3, IVDl3-l4, IVDl4-l5 and relative quantities with somatometric parameters in girls and women of the first adulthood (16-26 years) represented their gradual raising. Therefore, the arithmetic means of absolute correlation coefficients between particular sizes (height, sagittal and transverse sizes of IVDs) with somatometric parameters were from 0,120 to 0,170; at the same time coefficient for total sizes become 0,190. The using of ratios of the total sizes IVDs to weight-length factors led to increasing arithmetic means of absolute correlation coefficients with somatometric parameters to 0,507. The studying of interrelations between somatometric parameters with spondylometric dimensions of the lumbar, thoracic and cervical functional spinal units is a perspective one and can be used for the development of the further mathematical modeling to individualize prediction and early detection of pathological changes of the spinal motor segments.
