The reconstruction of the foot is a broad and complex topic often studied from the clinical perspective, but rarely studied from the point of view of Bioengineering. This paper shows a method of computer simulation by finite elements based on magnetic resonance imaging of a surgically reconstructed foot. After the creation of 3D models of the foot in different evolutionary stages and the use of data provided by static podobarography, the calculations show differences in the increase of deformation occurred in each of the tissues involved in reconstruction. It is made into two different evolutionary surgical times, taking into account the load characteristics of the patient in each. This allows us a theoretical idea of the behavior of tissues participating in the reconstruction as deformable material. In results section, it´s shown that the global volume of tissue decreases and adapts to the contours, the muscle is the tissue that further increases its relative value of deformation and fat is the tissue that greater deformation suffers in terms of absolute values refer. The bone mechanical properties hardly undergoes deformations. Deformations distribution is compatible with the clinical and evolves with time over. The contact surface and the maximum pressures are similar in the theoretical model and the experimental. The use of Bioengineering implemented to Plastic Surgery provides a great source of information that can be both used for comparison within the same patient or between different patients.
