摘要
目的探讨利用3D打印技术和逆向工程软件图像处理技术设计可用于手术中精确截骨矫形的导向板。方法选择1例胫骨骨折畸形愈合的患者,分别获得患侧肢体及健侧肢体的CT数据,利用逆向工程软件重建三维模型及健、患侧镜像重叠等获得最佳截骨平面,导入UG NX8.5中设计截骨导向板,最后导入3D打印机获得胫骨畸形模型及导向板,用于模拟手术操作及术中精确截骨。结果术前及术中模拟手术截骨矫形结果一致,截骨导向板与患者胫骨畸形愈合处精确匹配,骨折畸形矫正位置良好,下肢力线恢复,术后无并发症发生,术后及2个月随访显示情况良好。结论 3D打印技术和逆向工程软件设计的截骨板能使骨科医师术前进行精确的评估,从而缩短手术时间,减少术中放射量,提高手术的安全性及精确性。
Objective To develop and validate an individualized precisely navigation template using three-dimensional computer simulation program and reverse engineering software image processing technique.Methods Selected a patient with tibial fracture malunion.The affected side and the uninjured side bones scanning by CT were reconstructed.Quantified the best osteotomy plane by using reverse engineering software restructuring,uninjured side mirror image and superimposing techniques,then imported the plane to UG NX8.5 to design an individualized navigation template,which was used for precise osteotomy.Results A corrective osteotomy was achieved as expected,and the navigation template exactly matched with malunion.The fracture deformity was significantly corrected,and the axial alignment of the lower extremity was restored.No complications happened,postoperative recovery and 2 months of follow-up was in good condition.Conclusion Reverse engineering and three-dimensional computer simulation program make the osteotomy more accurate,shorten the operation time,reduce intraoperative radiation,and improve the accuracy and safety of surgery.
