Purpose Several studies have been conducted to determine morphometry of lumbar vertebrae, mostly in western population and data on other populations is relatively sparse. Most of these studies have been carried out using fresh cadavers or osteological collections and several of them having limitations such as a small sample size and lack of demographic information. We conducted morphometric analysis of the lumbar vertebrae in a relatively large number of Indian patients using computed tomography scan. Vertebral body and pedicle dimensions of lumbar spinal elements were documented in Indian population and compared with other studies from the subcontinent as well as from other parts of the world. The morphometric data thus compiled may help in the development of new spinal implants for transpedicular screw fixations. Methods An observational study was conducted and a total of 302 patients were evaluated. Thin section computed tomographic images of the 12th thoracic vertebra (D12) to 1st sacral vertebra (S1) were acquired and various dimensions of vertebral body and pedicle were recorded and analyzed. Results Generally, the lumbar vertebral and pedicle dimensions were found to be greater in male patients. Comparison of dimensions in different populations revealed statistically significant differences in pedicle dimensions between Indian population and others. Conclusion Morphometric analysis of lumbar vertebrae using computed tomography scan provides measurements of different vertebral dimensions. This will help in development of spinal implants in future to meet the specific needs of the studied population.

Lumbar intervertebral disks: morphometric parameters and indices

et al. 2021

An important element of evidence-based medicine is to take into account the individual variability of the indicators of the norm of intervertebral discs, which is undoubtedly the basis for early preclinical detection of their pathology. Mathematical modeling and comprehensive assessment of the parameters of the intervertebral discs can not only predict and determine the early manifestations of pathological changes, but also help to correct them in advance. The aim of the study was to calculate and evaluate the variability of absolute, calculated and relative metric parameters of intervertebral discs in the norm with the subsequent possibility of modeling standards based on individual linear dimensions of intervertebral discs of the lumbar spine and general anthropometric characteristics (body length and weight) in young men and men of the first period of adulthood (17-28 years), both in separate age groups and in the combined group. The series of MRI scans obtained on a Phillips Achieva 1.5T scanner measured the anterior, middle and posterior vertical dimensions, maximum sagittal and frontal dimensions of the intervertebral discs L1-L2, L2-L3, L3-L4, L4-L5 segments of the spine (IVDL1-L2, IVDL2-L3, IVDL3-L4, IVDL4- L5). We calculated the average height of the intervertebral discs, cross-sectional area and volume of intervertebral discs, as well as relative indicators - the ratio of the sum of sagittal and transverse dimensions, the sum of three dimensions, cross-sectional area and volume of intervertebral discs to the average intervertebral disc height. Statistical analysis of the obtained morphometric parameters was performed in the license package “STATISTICA 6.1”. The distribution of variation series indicators, their average values and standard errors, coefficients of variation and asymmetry were evaluated. It was determined that the sums of the transverse and sagittal sizes and the sums of the three sizes increase proportionally in the caudal direction, have a distribution of indicators as close as possible to normal, and their coefficients of variation are many times smaller than for cross-sectional areas and volumes. Indicators of the ratio of the sum of the sagittal and transverse size and the sum of the three sizes to the average height of the intervertebral discs have a variability of less than 10% and correspond to the characteristics of the general population. Body weight and length have significantly higher correlation coefficients with the sums of sagittal and transverse dimensions, the sums of three dimensions and cross-sectional areas than with the partial dimensions of the intervertebral discs.

Annotation. Individual variability of intervertebral discs is one of the factors that makes it difficult to recognize the early signs of their pathological changes before the onset of clinical manifestations. In the development of evidence-based medicine, it is important to use clear criteria for distinguishing between norm and pathology, taking into account individual variability. The “mathematical modeling” and a comprehensive approach to quantitative and qualitative assessment of intervertebral discs will help in the early detection of abnormalities, in the individualization of norm, as well as in modeling the parameters of the artificial intervertebral disc for reconstructive interventions. The analysis by methods of descriptive statistics and the correlation analysis for the purpose of further mathematical processing, selection of optimal parameters for mathematical modeling is carried out. Anthropometric characteristics (body length and body weight, mass-growth factor and mass-growth index) were determined in young women and women of the first period of adulthood (16-26 years), as in separate age groups and in the combined group. MRI of the lumbar spine was performed, followed by morphometry. Statistical analysis was performed in the license program “STATISTICA 6.1”. The mean values of the variation series, standard deviations, coefficients of variation and asymmetry, paired t-test, d-test of Kolmogorov-Smirnov type, Levene index were evaluated. It was determined that the sums of the transverse and sagittal dimensions and the sums of the three dimensions increase proportionally in the caudal direction, have a distribution of indicators as close as possible to normal, and their coefficients of variation are many times smaller than for cross-sectional areas and volumes. Indicators of the ratio of the sum of sagittal and transverse size and the sum of three sizes to the average height of the intervertebral discs have a variability of less than 10% and correspond to the characteristics of the general population. Body weight and body length have significantly higher correlation coefficients with the sums of sagittal and transverse dimensions, with the sums of three dimensions, and cross-sectional areas in comparison with the partial dimensions of the intervertebral discs.
