【摘要】：目的探讨3D打印技术在脊柱畸形矫正手术中的应用效果。方法将42例半椎体畸形患者纳入本研究,其中20例在3D打印技术指导下行脊柱畸形矫正手术的患者归为实验组,其余22例在CT三维扫描重建指导下行脊柱畸形矫正手术的患者归为对照组,观察2组患者手术情况、术后侧凸及后凸矫正效果、弓根钉位置准确率以及并发症发生情况。结果实验组手术时间及术中出血量均明显低于对照组,差异有统计学意义(P0.05);2组患者术后侧凸及后凸Cobb角均明显低于同组术前,差异有统计学意义(P0.05);实验组患者术后侧凸及后凸Cobb角均明显低于对照组,侧凸及后凸矫正率明显高于对照组,差异有统计学意义(P0.05);实验组患者椎弓根钉位置准确率明显高于对照组,并发症发生率明显低于对照组,差异有统计学意义(P0.05)。结论在脊柱畸形矫正手术中应用3D打印技术能够显著缩短手术时间,减少术中出血量,提高侧凸、后凸矫正效果以及弓根钉位置准确率,减少并发症发生,应用价值较高。
[Abstract]:Objective to evaluate the effect of 3 D printing technique in correction of spinal deformity. Methods Forty-two patients with hemivertebra deformity were included in this study. Among them, 20 cases were treated with 3D printing under the guidance of spinal deformity correction operation as the experimental group. The other 22 patients were divided into two groups under the guidance of CT 3D reconstruction. The results of operation, postoperative correction of kyphosis and kyphosis, the accuracy rate of pedicle nail location and the occurrence of complications were observed in the two groups. Results the time of operation and the amount of intraoperative bleeding in the experimental group were significantly lower than those in the control group (P0.05). The Cobb angle of kyphosis and kyphosis in the two groups were significantly lower than those in the same group before operation. The Cobb angle of scoliosis and kyphosis in experimental group was significantly lower than that in control group (P0.05), and the correction rate of scoliosis and kyphosis was significantly higher than that of control group. The difference was statistically significant (P0.05); the accuracy of pedicle screw placement in the experimental group was significantly higher than that in the control group, and the incidence of complications was significantly lower than that in the control group (P0.05). Conclusion 3D printing can significantly shorten the operation time, reduce the amount of intraoperative bleeding, improve the accuracy of correction of scoliosis and kyphosis, reduce the incidence of complications and reduce the incidence of complications.
