Comparative morpho-topometric characteristics of human TI and TVI vertebrae in the first period of adulthood and old age

Aim of the study was to conduct a comparative analysis of the linear dimensions of TI and TVI vertebrae in men and women in the first period of adulthood and in old age according to computed tomography (CT) of the chest. Material and methods : The work is based on CT results of 70 patients of the admission department of the State Clinical Hospital N 3 in Perm in 2023–2024. All patients agreed to a study conducted to exclude possible lung pathology. CT examination was performed on an Optima 660 computed tomograph (GE HealthCare, USA), the height, width and anteroposterior size of the TI and TVI vertebrae were measured. The sample included subjects with normal body weight, mesomorphic body type, without injuries and skeletal abnormalities in the anamnesis. The patients were divided into two groups: 30 people of the first period of adulthood (14 men aged 22–35 years and 16 women aged 21–35 years) and 40 elderly people (20 men aged 61–75 years and 20 women aged 60–75 years). Results . The height and width of TI and TVI vertebrae in both men and women in the first period of adulthood and old age do not differ ( p > 0.05). Age-related changes in the anteroposterior size of the TI vertebra in women consist in its increase ( p < 0.05), while in men the parameters do not change ( p > 0.05). The anterior-posterior size of the TVI vertebra in both men and women do not change ( p > 0.05). No signs of sexual dimorphism of the studied vertebral sizes were found ( p > 0.05). Conclusions. To carry out various diagnostic and therapeutic manipulations in the thoracic spine, a specialist doctor needs a solid body of knowledge about the morphotopometric features of the vertebrae associated with the age and gender of the subject. The results of this study will serve as a scientific foundation for the creation of normative evaluation tables and will become starting points for further research.
