Abstract

Objectives: To model and analyze the osteoporotic lumbar vertebra L2-L4 region and predict the stress patterns for different loading condition. Methods: Osteoporosis is a disease in which low bone mass density and micro deterioration of bone tissue causing bone fragility and high risk of fracture. Using the dry bone, the dimensions are measured and are compared with the literature dimensions. Based on these dimensions L2-L4 lumbar vertebral segment was modeled and meshed. Finite element model was developed to analyze the biomechanical properties of the vertebral body because of its complex anatomy. Findings: Intact model is validated for various range of motions and compared with the literature. Displacement in the end plates of vertebra are found and compared with the intact model. Applications: Implant for the osteoporosis patient can be designed using this Biomechanical study and can be analyzed for different loading conditions.
