Abstract
The research for new vertebro-somatometric correlations will significantly improve the possibilities of methods for individualizations of the normal parameters and will accelerate the introduction of scientific developments into the daily practice of clinicians, radiologists, neurosurgeons and other specialists. The aim of research is to investigate the peculiarities of relationships between partial linear dimensions of the lumbar intervertebral discs, their total sizes and relative indicators with somatometric parameters in the youth and young adult males in norm. The linear dimensions of the lumbar intervertebral discs (height, sagittal and transverse sizes) were measured noninvasively on the MRI images in the axial, sagittal and coronal plains. The somatometric investigation was performed individually with measuring of the general (length and weight of body) and particular sizes (the longitudinal sizes, the transverse sizes, the circumferences, pelvic sizes and skinfolds thickness). The bony, muscle and fat components of the body mass were calculated. Correlation analysis was performed in the «Statistica 6.1» license package. The arithmetic means of absolute correlation coefficients between particular and total individual sizes of IVDL1-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 0.080 – 0.150; for total sizes – 0.240; for ratio of the total sizes to the mass-growth coefficient – 0.490. Analysis of arithmetic mean values of absolute correlations with somatometric parameters in youth and young adult males in the norm (17-28 years) showed a gradual increase in the values of correlation coefficients and an increase in the number of significant correlations with maximum values in relative indicators. Thus, in youth and young adult males aged 18-28 years, the features of the relationship of somato-anthropometric parameters with the linear dimensions of the intervertebral discs of the lumbar spine in the norm were studied. The numerous relationships between the partial (height, sagittal and transverse sizes) linear dimensions and total sizes of the lumbar intervertebral discs in the youth and young adult males in norm (17-28 years) with their somatometric parameters were found. Thus, the use of relative indicators can be more acceptable in the subsequent mathematical modeling of individual indicators, in particular, the parameters of the intervertebral discs.

Qualitative assessment of the relationships between partial sizes, total sizes and ratios of the total sizes intervertebral discs (IVDs) to weight-length factor with somatometric parameters were performed by calculating of the arithmetic means of absolute correlation coefficients between particular sizes, total sizes of IVD, IVD, IVD, IVD and relative
The calculated arithmetic means of absolute correlation coefficients between particular sizes, total sizes of IVD, L1-L2
Summary
Lower back pain is directly associated with intervertebral disc degeneration [7, 15, 19]. 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 [10, 16, 35]. The constitutional and anatomical variations, the spondylometric parameters particularity of the functional spinal unit elements form an important prerequisites of spine pathology origin [20]. The obtained results of interrelations between linear intervertebral discs (IVDs). Correlations between linear dimensions of the lumbar intervertebral discs and somatometric parameters in the. Sizes with somatometric parameters for detection of spine pathology are used. 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
