Development of L4 and L5 Spinal VertebralFEA Model Using Image Processing Techniques

Abstract

In this new era of technology the fields of biology and engineering walk hand in hand. The finite element (popularly known as FE) tool is used here to analyze the lumbar vertebra L4 and L5. It is important to know the results of these vertebrae in case of healthy, abnormal and in generated case. The spine model was developed in MIMIC software from the computer topography (CT) data available. The model was analyzed in ANSYS and different results were observed which might be used in later studies of spinal cord. Stress distribution was also plotted and the results are plotted on the graph for the displacement of the vertebra under loading condition. The sole aim of this study is to find out the loading and stresses occurred on spinous process so that an alternative mechanical component with similar material properties will be developed.
