Obtaining three-dimensional models of human skeletal structures is a major challenge in computer vision, as evidenced by numerous researches in this field. Their objective is double, on the one hand they allow the generation of prosthesis, on the other, they allow studies like the kinematic or resistant. The main advances that have been achieved are associated with the reconstruction of bones from the medical images obtained by computed axial tomography (TAC) or magnetic resonance imaging (IRM). However, these medical tests involve, on the one hand, a high exposure of the individual to radiations detrimental to his health and on the other hand, a high economic cost. This paper presents a new proposal for reconstruction of bones based on geometric techniques of detection of contours, alignment of sections and meshing of surfaces. For this proposal it is necessary as starting information a frontal x-ray of the bone that supposes a low exposure for the individual and a significant reduction of the cost in front of other tests of medical character. The proposed method has been tested on a human tibia and the results obtained make this new strategy to be considered for the personalized reconstruction of bones.
