3D打印技术在儿童先天性脊柱半椎体手术治疗中的应用研究
Application of three-dimensional printing for congenital hemivertebra
摘要
Abstract
Objective To establish a solid model of congenital spinal hemivertebra body using three -dimensional(3D)printing technology and explore its application value of this model during hemivertebral surgery.Methods Retrospective analyses were performed for 40 surgical children diagnosed with congenital spinal hemivertebra deformity from September 2012 to May 2016.According to whether or not 3D printing technology was employed,they were divided into 2 groups of experimental(n=18)and control(n=22)groups.The duration of nailing operation,accuracy of placement and the incidence of neurovascular injury were compared between two groups.Results In control group,102 pedicle screws were implanted with an average setting time of 10 to 15 min and an accuracy of placement of 85.3%(87/102);In experimental group,94 pedicle screws were implanted with an average setting time of 5 to 8 min and an accuracy of placement of 94.7%(89/94).The duration of nailing operation and accuracy of placement were statistically significant between two groups(P<0.01).There was no perioperative occurrence of such complications as nervous or vascular injury.Conclusion Compared with traditional surgery without 3D printing,using preoperative patient CT data and producing spinal half-vertebral body model through 3D printing may guide operations so as to shorten the time setting nail and improving accuracy.关键词
