Abstract

Introduction. The use of finite element analysis methods in neurological practice will reveal informative signs of rehabilitation potential for choosing further tactics of restorative treatment of patients with cervical discogenic radiculopathy. Purpose — to study the possibilities of finite element analysis to determine predictors of rehabilitation potential in patients with cervical discogenic radiculopathy under rotational loads. Materials and methods. Based on the magnetic resonance imaging data of a 38-year-old patient (male), a model of the C5–C7 spinal motor segment was generated, including: the corresponding vertebrae, intervertebral disc, longitudinal ligaments, combined arched joints and spinal cord. By means of computer modeling and the finite element method, the stressstrain state of the cervical spine was analyzed in a patient with cervical discogenic radiculopathy under rotational load. The obtained data were compared with previously conducted experimental studies using computer simulation tools and clinical features of the course of cervical discogenic radiculopathy. Results. The relationship of bone-cartilaginous structures of the spine with spinal roots and spinal cord matter has been studied, stress diagrams by Mises have been obtained. When the anthropomorphic model was rotated to the left, disco-radicular conflicts were revealed at the level of the intervertebral disc C6–C7 with the outer posterolateral surface of the intervertebral disc. When rotating the model to the right, a disco-radicular conflict of spinal cord roots in foraminal zones at the level of discs C5– C6 and C6–C7 with the outer posterolateral surface of the intervertebral disc. Based on the obtained data on Mises stresses in the cervical vertebral-motor segment, a further “cascade” of degenerative-dystrophic processes under rotational loads was predicted. The qualitative analysis, which included a comparison of clinical data, corresponded with computer reproduction data. Conclusion. The use of finite element analysis in modeling the cervical spine in patients with discogenic radiuclopathy allows us to study the physical features (Mises stress limits) of the course of complicated forms of cervical dorsopathy (radiculopathy), which creates prerequisites for the study of informative prognostic signs of recovery in this category of patients.
