The utility model discloses a
metal 3D printing porous bone induction structure tibial
prosthesis, which comprises a
diaphysis prosthesis, a
bone fracture plate and an intramedullary nail, the
diaphysis prosthesis is designed according to the anatomical form of the focus part of a patient, the
diaphysis prosthesis comprises a
solid framework and a porous structure, and a cavity is arranged in the diaphysis prosthesis; the at least two
bone fracture plates are connected to the two ends of the diaphysis prosthesis in the
tibia direction respectively, and the at least two
bone fracture plates are connected with the
tibia near end and the
tibia far end through screws respectively. The tibia near end comprises a first
medullary cavity, the tibia far end comprises a second
medullary cavity, the intramedullary nail penetrates through the first
medullary cavity, the cavity and the second medullary cavity, and the two ends of the intramedullary nail are connected with the tibia near end and the tibia far end through screws respectively. The utility model can solve the problems of incapability of realizing rapid healing, poor
initial stability and poor long-term stability in the existing
bone defect reconstruction.
