Objective: the analysis of state of tension and strain at the level of lumbar vertebrae through finite element method.

Method and material: We started with CAD modelling of biomechanic structures, realising a model of sustainability of the lumbar vertebrae, after which we performed the analysis states tension and strain at the level of lumbar vertebrae using finite element method. For elaboration of the solid CAD model was used tomography scanning of a real human lumbar vertebrae. The model developed was subjected to different loads through successive iterations similar to those governing the spine in a car accident.

Results: Higher or lower incidence of certain injuries is not random, and can not be charged solely to the conditions of the accident occurrence, but is implicitly determined by the structural characters of the vertebrae and the size of the loading forces.
 

Key words: lumbar vertebrae, tension, deformation, resistance
