      STUDY OF THE STRESS AND DEFORMATIONS OF THE PROXIMAL FEMORAL EPIPHYSIS USING THE FINITE ELEMENT ANALYSIS (Abstract): 3 D reconstruction of body parts in general and of the bony system in special makes possible the study of certain static and dynamic characteristics and reproduces the in vivo behaviour of a biomechanical system. A 3 D femoral reconstruction was made starting from an anatomical piece – a human femur, scanned with high resolution CT scan. Based on the bone geometry and using the Solid Edge programme, we obtained a model of a solid bone and, consequently, the 3 D shape of the human femur was reconstructed, using the MIMICS application. After having obtained a tri dimensional bone model and based on imaging techniques, each area was assigned specific constants and was subjected to the finite element analysis, focusing on such elements as stress, equivalent stress, stress shearing and deformations, depending on the respective bone area, and finally making correlations with the quality of the bone substance in the respective areas.
Key words: 3 D RECONSTRUCTION OF FEMORAL SHAPE, FINITE ELEMENT ANALYSIS, STRESS, STRESS SHEARING, DEFORMATION
