BACKGROUND
Dorsopathies of the cervical spine are among the most common diseases of the musculoskeletal system. Neck pain is often associated with a degenerative-dystrophic lesion of the spine, but this is not always the case. The use of neuroimaging methods and statistical data processing in the assessment of pathogenetic factors of hernial protrusions (HP) formation is the most rational. In our study, an attempt was initiated to describe biomechanical processes in the structure of the cervical spine segment dorsopathy.
OBJECTIVE
To study of the isolated influence of biomechanical factors on the process of formation of dislocations of disc material (protrusion) beyond the space of intervertebral discs of the cervical spine.
MATERIAL AND METHODS
The object of the study was a random sample consisting of 124 MRI studies of the cervical spine of various patients. All studies were divided into 9 groups according to the types of neck: short thick, short intermediate, short thin, medium thick, medium intermediate, medium thin, long thick, long intermediate, long thin (1—9, respectively).
RESULTS
Biomechanical factors have an isolated effect on the hernial protrusions formation of the cervical spine. The main criterion for evaluating the effectiveness of the (vertebrae-movement segment) VMS lever is the value of tg α, which is defined as the ratio of 1/2 of the height of the disc at the level of the anterior edge of the vertebrae in the sagittal plane and the segment connecting the center of the line between two intervertebral joints centers and the anterior edge of the intervertebral disc. The data obtained indicate that the effectiveness of the VMS lever CV—CVI and CVI—CVII has the greatest impact on the formation of intervertebral disc protrusions at a young age.
CONCLUSION
The study demonstrated a significant influence of the biomechanical factor on the process of herniated protrusions of intervertebral discs in the cervical spine in young people, while it is obvious that in older people the mechanical factor has the least effect, which is probably due to age-related and degenerative changes in intervertebral discs. The proposed method for assessing the influence of a mechanical factor on the formation of intervertebral discs protrusions makes it possible to predict the development of cervical dorsopathy in young people, and also, with further study, can be used in modeling postoperative complications of surgical treatment on the cervical spine using implants. The introduction into the routine practice of MRI research of a method for assessing the effect of a lever of the 2nd kind on the process of forming the displacement of disk material will increase the informativeness of the study and personalize the treatment process, develop an individual set of preventive medical measures.
