“…A recent systematic review demonstrated that 3D printing technology in orthopedics improves operative time, blood loss, fluoroscopy times, bone union time, pain, accuracy, function, and without an increase in operative complications[ 12 ]. Besides being used for preoperative planning, surgery simulation, intraoperative navigation, patient education, and doctor-patient communication, 3D-printing technology has shown emerging and promising application in personalized spinal implant and reconstructive surgery[ 13 , 14 ]. Given the novelty of 3D-printed spinal implants, it is essential to conduct more prospective studies to explore its specific application scope, experience, outcomes, and potential problems[ 15 , 16 ].…”

Three dimensional (3D)-printing technology facilitates complex spine surgery with unique advantages in artificial vertebral body design and manufacturing. In this study, we aimed to demonstrate how a 3D-printed spinal implant is utilized in the management of multi-level spinal tumors and integrates with comprehensive oncologic treatment. Eight spinal or paraspinal tumor patients requiring spinal reconstruction after total en bloc spondylectomy were selected as candidates for 3D-printed titanium artificial vertebral body implants. All patients underwent surgery on three or more vertebral segments or complex spinal junction segments. The clinical, oncological, and surgical characteristics of patients were collected. Of the eight candidates, seven suffered from pain and/or limb disorder. Six underwent successful 3D-printed spinal implantation, while two failed due to implant mismatching and were converted to conventional reconstruction. Of the six patients undergoing 3D-printed spinal implant surgery: (i) Five had recurrent tumors; (ii) three underwent neoadjuvant therapy; (iii) the median surgery time was 414 min; (iv) the median blood loss was 2150 ml; (v) the median blood transfusion was 2000 ml; (vi) the median length of hospital stay was 9 days; (vii) four patients received adjuvant therapy after surgery; and (viii) all patients experienced no pain, moved freely, and had no local recurrence at a median of 11.5 months post-operative follow-up. Spinal reconstruction with a 3D-printed titanium artificial vertebral body allows for total en bloc resection of complex multi-level spinal tumors. Combined with neoadjuvant and adjuvant therapy, these patients had excellent postoperative outcomes, long-term normal spinal function, and associated low local recurrence probability.

“…The actively developing technique of INT manufactured using 3D printing technologies has become the subject of multiple studies devoted to its application in all parts of the spine [14][15][16][17][18][19][20][21]. The use of templates in the lumbar spine is limited by the anatomical features of this area, namely, the paravertebral muscles preventing the adequate positioning of the INT when choosing the classical transpedicular trajectory of implantation [22,23].…”

Subcortical screw placement is currently performed using frontal view fluoroscopy or intraoperative O-arm navigation system. The emergence of a novel technique for spinal navigation based on individual navigation templates created using 3D printing technology determines the need to study their safety and effectiveness in subcortical implantation. The aim of the study was to evaluate and compare the efficacy of subcortical implantation of pedicle screws in the lumbar spine using individual navigation templates versus intraoperative fluoroscopy. Materials and Methods The study was based on the analysis of treatment results in 39 patients who underwent surgery with subcortical implantation of 130 screws using the MidLIF technique. In group 1, navigation templates were used, in group 2 — intraoperative fluoroscopic control. Comparative analysis of implantation correctness and time, the total operation time, and radiation load was performed. Results The mean distance between the screw and the cortical plate recorded in the groups ranged within 1.20–3.97 mm, without statistically significant difference (p>0.05). The mean time of pedicle screw implantation was 137.0 [115.25; 161.50] s in group 1 and 314.0 [183.50; 403.25] s in group 2. The total operation time was reduced from 173.0 [155.0; 192.25] min in group 2 to 119.0 [108.0; 128.75] min in group 1. The average of 1.0 [1.0; 2.0] X-ray image was performed to place one screw in group 1, while it was 12.0 [10.0; 13.25] in group 2. The differences between the groups in terms of implantation time and radiation load were statistically significant (p<0.05). Conclusion Compared with intraoperative fluoroscopy, the use of individual navigation templates for subcortical implantation of pedicle screws provides their correct positioning with a significant reduction in both operation time and radiation load at similar safety.
