Abstract:

BACKGROUND: In three-dimensional CT reconstruction model, fracture virtual reduction and internal fixation cannot be achieved, and reasonable operation scheme cannot be formulated. It cannot fully meet the needs of clinical orthopedics physicians.
OBJECTIVE: To explore the methods to perform three-dimensional reconstruction, reduction on proximal tibial fracture and to design digital plate using software.
METHODS: Nine specimens of knee joint were built to be A1-3, B1-3 and C1-3 types of proximal tibial fracture according to the AO standard. All specimens were treated with CT scan. Three-dimensional reconstruction and reduction on nine types of bone fracture models were performed in Mimics. The digital plates and screws were designed in Solidworks. Virtual internal fixation on the reduced three-dimensional models was performed.
RESULTS AND CONCLUSION: All bone fracture models received three-dimensional reconstruction and reduction, and the design for internal fixational plates and screws as well as virtual internal fixation were accomplished. A3, B3 and C3 types were presented. These results suggest that the digital plates for proximal tibial fracture could be designed in Mimics and Solidworks with a personal computer. Our experience could be used in the real operation.
