3D打印技术在脊柱侧凸矫形术中的应用研究

目的:通过3D打印技术建立患者脊柱的立体实物模型,并探讨其在脊柱侧凸矫形手术中的临床应用价值。方法:2013年9月～2017年8月的15例脊柱侧凸畸形患者,采集患者的薄层CT扫描数据,利用3D打印技术建立实物模型,术前模拟置钉、模拟截骨,完善术前规划,并按照术前计划进行手术。结果:所有患者均按照根据术前3D打印模型制定的手术方案完成手术,术中置钉顺利,置钉准确率为93.6%。所有患者术中、术后无神经、血管、内脏损伤等并发症。结论:3D打印技术为术者提供了更加直观、立体、即时的影像资料,能够完善术前规划,提高置钉准确率,降低手术风险,在脊柱矫形手术中应用前景广泛。

Application of 3D Printing Technology in Scoliosis and Orthopaedic Surgery

ABSTRACT Objective: To establish a three-dimensional physical model of patients'' spine by 3D printing technology and to explore its clinical value in scoliosis and orthopaedic surgery. Methods: From September 2013 to August 2017, 15 cases of scoliosis deformity were collected by CT scan data, and the physical model was established by 3D printing technique. The preoperative simulation of nail, simulated osteotomy, improvement of preoperative planning, and operation according to the pre operation plan. Results: All patients completed the operation according to the preoperative 3D printing model, and the nail placement rate was 93.6%. All patients had no complications such as nerve, blood vessel and visceral injury during and after operation. Conclusion: 3D printing provides more visual, three-dimensional and immediate image data for the operator. It''s helpful for diagnosing and operation planning. It can improve the preoperative planning, improve the accuracy of nail placement, reduce the risk of operation, and have a wide range of applications in the scoliosis and orthopedic surgery.
