|Title of the thesis:||Mechanical response of human spine|
|Summary:||The work is oriented to the modeling of the human spine, particularly its whole lumbar and thoracic part and two cervical vertebrae. The spine is considered as a load bearing 3D system. The models and analyses are performed in computer program ANSYS. The aim is to model the spine as precise as possible, that is why it is important to have the knowledge about the anatomy too. Biomechanics, as a scientific discipline, uses and applies the engineering principles to biological systems. In this case the principles of mechanics are taken into consideration. Human spine model includes determination of geometry based on X-ray pictures of dorsal and lateral projection. For this reason, another computer code SPINESCAN was developed as a helping tool to obtain the most realistic model of the spine. Various positions, deformation, scoliosis, rotation, torsion can be modelled. Once the geometry and so the model is done, external loading on different spinal segments is entered and consequently response could be analyzed. In this case, three variations -- regular spine (only with physiological curvature), scoliotic spine (with physiological and pathological curvature) and spine with partial scoliosis - of the particular patient's spine was modelled, loaded statically and also dynamicly and analysed. As far as the procedure and outputs are very variable, this can contribute a lot to the medical practice, as a tool for diagnosing, developing the implants or other artificial instruments for spine fixation.|
