Dynamics of morphotopometric characteristics and X-ray density of T<sub>VI</sub> vertebra in men from the first period of mature age to old age

Aim – to evaluate the dynamics of anteroposterior dimensions and X-ray density of the TVI vertebra in men from the first period of adulthood to old age according to computed tomography (CT) of the chest. Material and methods. The work is based on the results of CT scans of patients undergoing chest examinations. The height, width, anterioposterior dimension, and X-ray density of the TVI vertebra body were measured. The study sample consisted of individuals with normal body weight, mesomorphic body type, without history of injuries and skeletal abnormalities. 60 patients were randomly selected from 78 subjects, so that each group had the same number of patients: 20 people. The first group consisted of men of the first period of adulthood (22-35 years of age), the second group included men of the second period of adulthood (36-60 years of age), the third group consisted of elderly men (61-75 years of age). Results. The study revealed a tendency for the TVI vertebral body height parameters to decrease by 7.8% in old age (t = 2.01; p 0.05). A tendency for the TVI vertebral body width parameters to increase by 2.18% in old age (t = 0.54; p 0.05) was revealed. At the same time, a tendency for the anteroposterior size parameters of the TVI vertebral body to increase by 2.25% was determined (t = 0.60; p 0.05). The X-ray density indices of the TVI vertebral body are characterized by a significant decrease in parameters with increasing age (p 0.001). Conclusion. As a result of the conducted intravital study, new data on the age-related anatomy of the TVI vertebra in men were obtained. Since the anatomical parameters of the vertebra are not static values and change with age, this information will useful in clinical practice of such specialists as gerontologists, traumatologists, vertebrologists, radiation diagnosticians, in sports medicine and in the work of exercise therapy doctors.
