3D Printing Adjustable Stiffness External Fixator for Mechanically Stimulated Healing of Tibial Fractures

Figure 2

Block structure design process: (a) 3D geometrical model of tibial fracture with pins after reduction; (b) the division line of the front and back parts of the external fixation was determined based on the position of the pin passing through the fractured leg; (c) Voronoi shapes randomly distributed on the surfaces of the two parts of the fractured leg; (d) the obtained geometric model of the block structure external fixator cast.
