目的：探讨青少年特发性脊柱侧凸数字化虚拟手术设计系统建立的方法及其在临床应用中的价值。方法选取1例青少年特发性脊柱侧凸患者，经16排螺旋CT扫描获取影像数据。采用Mimics 16.01软件对脊柱侧凸影像数据进行三维重建，并对三维重建模型进行数字化三维测量及置钉手术模拟。测量固定内植物的长度、横径及方向，模拟手术经过并在临床应用中使用术前模拟数据。结果重建出青少年特发性脊柱侧凸的三维数字化虚拟可视模型，配准虚拟螺钉和椎弓根-肋骨复合体的位置，使虚拟螺钉不穿透椎弓根内侧皮质及椎体前缘，设定完整的手术方案。利用术前规划方案进行手术，手术置钉效果满意，无螺钉穿透椎体前缘皮质和椎管皮质。结论验证了特发性脊柱侧凸手术术前三维数字化手术设计并制定手术方案，可以显著提高手术成功率。“,”Objective To study the methods of 3D digital preoperative design on adolescent idiopathic scoliosis and the application value of it. Methods One adolescent idiopathic scoliosis patient was chosen,Mimics16.01 was used to reconstruct 3D model,and measure the parameter of the pedicle rib complex screw angle,screw length and width of screw,and parameter was applied in operation. Results The 3D model of adolescent idiopathic scoliosis was reconstructed,and the screw and pedicle rib complex was positioned,and the screw was prevented to penetrate the pedicle and vertebral body;the plan of operation was carried out, and the screw didn’t penetrate the pedicle and vertebral body. Conclusion The digitalized visualization of adolescent idiopathic scoliosis could increase the success ratio.
