This paper presents a method for building a three dimensional model of the lower leg bone (tibia) \udfrom a human, from X-ray images. The methodology adopted to obtain the 3D object is deforming \udthe model until it corresponds to X-ray images (front and left and right sides) of the tibia. We used \udthe following algorithms for X-ray images segmentation and three-dimensional modeling: Canny, \udBorder Following, Free Form Deformation (FFD) and deformation algorithm developed in this \udwork. The viewing application defined and implemented shows the three-dimensional image of \udthe bone of the tibia resulting from deformation of the 3D object. The experimental results \uddemonstrate the possibility of representing the real human bone obtained from X-ray images into \uda 3D model, however, a great difficulty for this activity was the number of images available for the \udprojec
