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

Figure 1

Representative pictures showing the establishment of the acetabular bone defect model and implantation of the 3D printed porous Ti6Al4V augment into miniswine. (a) The size of the acetabular bone defect was determined by a ruler. (b) The anterosuperior wall of the acetabulum was exposed clearly. (c) The bone defect model was completely created (the yellow triangle). (d) The size of the osteotomized bone was measured. (e) The 3D printed porous Ti6Al4V augment was temporarily fixed by two K-wires. (f) Two screws were inserted into the augment screw holes.
