摘　　要：目的:探讨3D打印重度肋骨骨折模型的临床应用。方法:对9例重度肋骨骨折患者,共50处肋骨骨折,进行3D重建,采用3D打印技术,打印1:1物理模型,并测量肋骨骨折处高度及弯曲度,选择合适的接骨器型号进行体外模拟复位和内固定术。最后,根据3D打印模型及数据参数指导临床内固定术。同时,利用3D打印模型进行临床教学及医患沟通。结果:(1)3D打印结果:3D重建及3D打印模型均获得清晰的立体解剖结构,3D打印模型更直观真实。(2)根据3D打印模型测量的数据参数选取肋骨接骨器,均完全符合目标肋骨的要求。(3)3D打印模型有助于临床教学及医患沟通。结论:3D打印肋骨骨折模型有助于准确诊断重度肋骨骨折,有助于合适接骨器的准备及术中操作导航,从而减少手术创伤;通过3D打印模型,有助于医患沟通和临床教学。Objective To explore the application of three-dimensional（3 D） printed severe rib fracture model in clinic. Methods 3 D printing technology was used to perform 3 D 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 3 D printed model and the obtained data were used to guide the clinical internal fixation. Meanwhile, the 3 D printed model was applied for clinical teaching and doctorpatient communication. Results 3 D printed results showed that the clear 3 D anatomical structures could be obtained with the use of 3 D reconstruction or 3 D printed model, and the 3 D printed model was more intuitive and real. The selected rib connectors based on the data measured by the 3 D printed model completely met the requirements of the target rib. 3 D printed model was conducive to clinical teaching and doctor-patient communication. Conclusion 3 D 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, 3 D printed model is helpful for doctor-patient communication and clinical teaching.
