In Vivo Reconstruction of the Acetabular Bone Defect by the Individualized Three-Dimensional Printed Porous Augment in a Swine Model

Figure 2

The graphical illustration of the design of the 3D printed porous Ti6Al4V augment and the micro-CT imaging of the acetabulum along with the augment taken from miniswine 3 months after implantation. (a) The thickness of the porous Ti6Al4V coating was 1 mm, and the rest of the augment was solid Ti6Al4V. (b) The designed length of screws was 16-20 mm. (c) The designed direction of screws. (d) The final design of the 3D printed porous Ti6Al4V augment fixed on the acetabulum. (e) The micro-CT imaging showing bone formation within the porous augments, and the specimen was taken 12 weeks after surgery (the inset in the upper-right corner). (f) The enlarged photo of the 3D printed porous Ti6Al4V augment.
