The implants used in surgery.
A: The implanting system included 3D-printed prosthesis, vascularized fibula, bioceramic granules, and plates.
B: β-TCP bioceramics granules (irregular, with a diameter of 1.5–3.5 mm).
C: Microstructure of the β-TCP bioceramics granules (the pore with a diameter of 500–600 µm and the interconnection with a diameter of 120 µm).
D: Composite (consisted of 3D-printed prosthesis, β-TCP bioceramics granules and vascularized fibula).
