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

Figure 1

CT data acquisition and 3D modeling. (a) X-ray image of the fracture without pins; (b) patient leg after pin insertion; (c) 3D model reconstructed from CT data obtained after pin insertion; (d) virtual reduction and fixation: reconstructed 3D model of the fracture; (e) the reduction was cross-checked with reconstructed 3D fracture images and virtual reduction of the model. Two fracture blocks were reduced, and their accuracy was observed from different views; (f) final 3D geometrical model of tibial fracture with pins after reduction and fixation.
