The aim of the study was to evaluate the efficiency of Finite Element Method (FEM) modelling of the clinical cases of traumatic cervical spinal cord injury (SCI). The study population consisted of 28 patients suffering from traumatic cervical spine injury with (study group) and without (control) neurological deficits. A numerical simulation of the trauma event was performed, based on validated 3D FEM model. All the results obtained underwent statistical analysis. Statistically significant differences between both groups were found in severity of bony and neural structure damage as well as in stress and strain ratios. The highest values of tensile stress and deformation were noted in the sagittal (Y) axis. The maximum stress and strain were found in anterior spinothalamic, lateral spinothalamic and dorsal columns. It was also found that stress and strain in each segment and axis of the spinal cord model were positively correlated with the severity of the cervical spine injury (R-Spearman 0.39 to 0.64) and neurological symptoms of SCI (R-Spearman: 0.43 to 0.82). It is possible to create a clinical numerical model of the SCI with the use of FEM. The correlations between the mechanical force and neurological deficits show tendencies which require further studies based on an improved model and a greater number of patients.

According to up-to-date knowledge only mathematical modelling of the spinal cord injury (SCI) may provide real insight into a spatial location of the fields of the spinal cord mechanical strain generated by the injury. The purpose of our research was to correlate the results of Finite Element Analysis of SCI with the patient’s neurological state and the injured spinal cord MR imaging. The 3D Finite Element Model of the cervical spinal cord and vertebral canal of a 21-year-old male patient was created. The moment of the injury was reconstructed by a simulation of the displacement of nonelastic structure to the light of vertebral canal. A detailed spatial analysis of the stress, strain and dislocation distribution was performed. The most injured region was the superficial zone of the white matter, the anterior part and central region of the grey matter, which was in good agreement with patient’s neurological staus. An individualized Finite Element Model of traumatic SCI constructed by us enabled the evaluation of the influence of mechanical strain on a neurological condition of a patient. Further research will consist in validation of the results of endurance analyses based on a enlarged group of patients.
