- Abstract:
- ObjectiveTo establish a solid model of congenital spinal hemivertebra body using threedimensional (3D) printing technology and explore its application value of this model during hemivertebral surgery.MethodsRetrospective 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.ResultsIn 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.ConclusionCompared with traditional surgery without 3D printing,using preoperative patient CT data and producing spinal halfvertebral body model through 3D printing may guide operations so as to shorten the time setting nail and improving accuracy.
