Abstract:: Abstract: Objective To explore the application of three-dimensional (3D) printed severe rib fracture model in clinic. Methods 3D printing technology was used to perform 3D reconstruction of 50 fractured ribs in 9 patients with severe fractured ribs, and print them to 1:1 physical model. Then the height and curvature of the fractured ribs were measured for selecting the appropriate bone connectors to simulate fracture reduction in vitro and perform internal fixation. Finally, the 3D printed model and the obtained data were used to guide the clinical internal fixation. Meanwhile, the 3D printed model was applied for clinical teaching and doctor-patient communication. Results 3D printed results showed that the clear 3D anatomical structures could be obtained with the use of 3D reconstruction or 3D printed model, and the 3D printed model was more intuitive and real. The selected rib connectors based on the data measured by the 3D printed model completely met the requirements of the target rib. 3D printed model was conducive to clinical teaching and doctor-patient communication. Conclusion 3D printed rib fracture model is useful for the accurate diagnosis of severe rib fracture and contributes to the preparation of proper bone connectors and intraoperative navigation, reducing surgical traumas. Moreover, 3D printed model is helpful for doctor-patient communication and clinical teaching.
