目的:探讨电子计算机断层扫描(CT)、图像三维(3D)重建及三维(3D)打印在跟骨粉碎性骨折的辅助指导与诊断意义.方法:以医院确诊跟骨粉碎性骨折患者作为研究对象,对跟骨进行CT扫描,采用计算机辅助技术对数据进行处理,3D打印1∶1立体模型,依此进行术前医患沟通、钢板预塑和螺钉定位,制定个性化手术方案并加以模拟,指导手术治疗.结果:术中骨折情况与3D打印模型基本一致.结论:模拟手术能减少实际手术时间及手术中出血量,提高骨折复位、固定的准确性,减少并发症,同时缓解医患关系.“,”Objective:To investigate the computed tomography (CT),three-dimensional (3D) reconstruction and three-dimensional (3D) printed on the foot with comminution assisted guidance and diagnostic significance of fracture.Methods:Diagnosed with foot fracture patients as the research object,CT scan of the foot,the data were analyzed by computer aided technology,3D printing 1∶1 models,in order to preoperative doctor-patient communication,steel plate pre-plastic and screw positioning,personalized surgical procedures and simulation,guiding surgical treatment.Results:Intraoperative fracture model consistent with 3D print.Conclusion:Simulated surgery can reduce the actual operation time and the amount of bleeding in operation,improve the accuracy of fracture reduction and fixation,reduce complications,and ease the doctor-patient relationship.
