Abstract
Currently, the variability of the anatomical structures of the neck is increasingly being considered from the standpoint of typical anatomy. The wide possibilities of magnetic resonance imaging make it possible to study the variability of the cervical spine from the standpoint of typical anatomy. Purpose of the study: to determine the patterns of anatomical variability of the cervical spine according to magnetic resonance imaging in individuals with different neck shapes. The material of the study was magnetic resonance imaging of the cervical spine without pathological changes in 125 people of both sexes aged 25 to 70 years. On sagittal tomograms, the magnitude of cervical lordosis was determined according to the method of Y. Zhu et al. (2020). To assess various types of bends of the cervical spine, the method of determining the angle of the axis of V.T. Pustovoitenko et al. (2012). As a result of the study, the range of normative values of indicators characterizing the bends of the cervical spine according to magnetic resonance imaging in the norm was determined, taking into account the typical variability of the neck. The angle of inclination of the first thoracic vertebra was 24,5±1,34°, the angle of the upper thoracic inlet was 67,4±1,65°, the angle of the axis was 22,3±1,94°. The frequency of occurrence of various types of bends of the cervical spine in patients with normal, wide and narrow neck shapes was established. Persons with a normal neck shape are characterized by a high frequency of physiological lordosis, which is 81% according to the study. With a wide neck shape, hyperlordosis is most often determined (37%), physiological lordosis is observed in 32% of cases. In those examined with a narrow neck shape, mild lordosis is predominantly determined, which is 50% of all cases studied. The data obtained will allow interpreting the results of magnetic resonance imaging, taking into account the typical variability of the examined.
