Introduction There was a lack of attention to the screw placement techniques for surgical treatment of scoliosis in children and adolescents. This meta-analysis aims to compare the accuracy and safety of pedicle screw placement between 3D-printed navigation template technique and free-hand technique during corrective surgery for scoliosis in children and adolescents. Methods A comprehensive search was conducted for relevant articles up to December 2021 in databases including PubMed, Embase, MEDLINE, Cochrane, and Web of Science. The systematic meta-analysis compared the efficacy of pedicle screw placement between the two techniques, including accuracy of pedicle screw placement, complication rate, operation time, blood loss, mean place time per screw, and mean times for fluoroscopy. Results The seven studies involved 229 patients altogether. A total of 2805 pedicle screws were placed by two methods. Our results revealed that the 3D-printed guide template technique was more accurate than the free-hand technique in pedicle screw placement (OR=2.96; 95% CI, 2.24~3.91, P˂ 0.000) with a lower complication rate (OR=0.21; 95% CI, 0.06~0.78, P=0.02). The operation time (MD= -34.37, 95% CI, -67.47~-1.28, P=0.04) and mean place time per screw (MD= -3.11, 95% CI, -6.13~-0.09, P=0.04) and mean times for fluoroscopy (MD= -6.60, 95% CI, -8.66~-4.55, P<0.000) significantly decreased among patients in the 3D-printed navigation template group compared with those in the free-hand technique group. In addition, the two techniques had no significant statistical difference in blood loss. Conclusions Compared with the traditional free-hand technique, the 3D-printed guide template is a promising technique with higher accuracy and safety in screw placement for the surgical treatment of scoliosis in children and adolescents and is worth popularizing and validating by more prospective clinical studies.

“…Many models lack relevant intraoperative features such as crucial neurovascular elements, ligamentous structures, and coagulation for hemostasis [ 8 , 10 , 12 , 13 ]. In addition, Park et al [ 11 ] and other studies [ 21 ] report the unrealistic non-osseous feeling of spine models, as well as the failure to recreate dynamic spinal kinematics. Without these features, trainees may be subject to decreased educational value and false confidence [ 22 ].…”

The utilization of three-dimensional (3D) models has been an important element of medical education. We demonstrate a three-dimensionally-printed (3DP) thoracic spine model for use in the teaching of freehand pedicle screw placement. Neurosurgical residents with varying years of experience practiced screw placement on these models. Residents were timed, and models were evaluated for medial and lateral breaches. Overall, this technical report describes the utility of 3D spine models in the training of thoracic pedicle screw placement. The tactile feedback from the 3D models was designed to represent both cortical and cancellous bones.
