Aplicación de metodologí de modelado 3D utilizando Tomografías Computarizadas para su análisis numérico

This paper presents a methodology for generating a model of human and porcine lumbar spine from CT Scans. Nowadays, the use of CT Scans as a biomodeling tool is a technique widely used in the development of computational numerical analysis based on Finite Element Analysis (FEA), thus the simple and/or complex anatomical structures can be visualized and analyzed. Thus, the relevance of this paper lies in the fact generation numerical analyses biomechanical with results very close to experimental analyses creating medical solutions in the design of prosthetic devices. Numerical results show a stress concentration in the intervertebral disc just in the end plates, both in the human case as in pigs, which is consistent with previous experimental analysis. Thus, it is concluded that the results obtained through this technique validate previous experimental analysis, however, it is necessary to take into account the characteristics the mechanical behavior of the different biological tissues that form the lumbar spine.
