目的：观察利用数字化导向模板技术和3D打印制作的个体化逆向耻骨上支外侧髓内拉力螺钉导向模板的可行性。
方法：回顾性选择1例骨盆骨折患者，男性，23岁，分型为LCⅡ型骨折。根据CT薄层扫描数据输入3D打印机打印1：1骨盆模型，Mimics等软件设计钉道并通过逆向工程软件设计数字化导向模板，3D打印导板固定模型后置入直径2.0 mm克氏针，通过影像学观察其准确性。
结果：3D打印的骨盆模型及数字化个性化导向定制的手术导向板能够满足耻骨上支外侧骨折置钉的要求，克氏针置入后经X线及CT证实与手术设计一致，导板与骨性标志贴合良好。
结论：基于3D打印技术的个性化导向模板可实现逆向耻骨上支外侧髓内拉力螺钉置钉的精确置入，并且可以节省手术时间及减少患者及医护人员的射线暴露次数。 |

Abstract:
Objective: To investigate the feasibility of a drill template for the placement of reverse intramedullary lag screws on the outside of the pubis based on digital design and 3D printing technology.
Methods: The preoperative CT images of a 23-year-old male patient with pelvic fracture were collected retrospectively.According to the Young and Burgess classification, the type of pelvic fracture was LCⅡwith the 3D printing technology.The data was reconstructed by 3D imaging reconstruction software to produce 1:1 three dimensional model.The screw channel and the individual drill template was designed by the softwares of Mimics 10.01 and Geomagic 12, the accuracy of a drill template was observed by X-rays and CT scans after the placement of 2.0 mm K-wires in the three dimensional template fixed on the model.
Results: Three dimensional pelvic model and digital, individual drill template could meet the requirement of the placement of reverse interamodullary lay screw for the treatment of superior ramus of pubis fracture.K-wire was placed and the accuracy of screw placement was confirmed using the X-ray and CT scanning.Template and the corresponding anatomical landmark fitted well.
Conclusion: With the assistance of the individual design and 3D printing technology, the accurate placement of superior ramus of pubis fracture screws can be realized.This technology is helpful to reduce the operation time and X-ray exposure of the patients and doctors. |
