“…The thinner the slices were, the less image noise presented; thus, the more sensitivity and specificity they produced. 26,47 Moreover, the FPA system did not seem to have a direct effect on improving pedicle screw accuracy. No specialized technology in the drilling tool functions to detect or reduce pedicle breach.…”

“…11 The postoperative CT scan evaluation to assess the accuracy of PS in this trial was 5 mm thick; meanwhile, the ideal CT scan thickness for spine evaluation is 1-2 mm. 26 The definition of pedicle breach and safe zone (in relation to the risk of injuring vital structures) differed among trials. Two trials classified the pedicle into 3 grades: no breach, up to 4 mm breach, and > 4 mm breach.…”

Study Design: Systematic review and meta-analysis. Objective: Various methods of pedicle screw (PS) placement in spinal fusion surgery existed, which can be grouped into conventional freehand (FH), modified freehand (MF), and image-guided methods (including fluoroscopy-based navigation (FL), computed tomography-based navigation (CT-nav), robot-assisted (RA), and ultrasound-guided (UG)). However, the literature showed mixed findings regarding their accuracy and complications. This review aimed to discover which method of PS placement has the highest accuracy and lowest complication rate in pediatric and adolescent spinal fusion surgery. Methods: A comprehensive search in MEDLINE (PubMed), EMBASE (OVID), CENTRAL, and Web of Science was conducted until May 2020 by 2 independent reviewers, followed by bias assessment with ROB 2 and ROBINS-I tools and quantification with meta-analysis. Overall evidence quality was determined with GRADE tool. Results: Four RCTs and 2 quasi-RCTs/CCTs comprising 3,830 PS placed in 291 patients (4-22 years old) were analyzed. The lowest accuracy was found in FH (78.35%) while the highest accuracy was found in MF (95.86%). MF was more accurate than FH (OR 3.34 (95% CI, 2.33-4.79), P < .00 001, I2 = 0%). Three-dimensional printed drill template (as part of MF) was more accurate than FH (OR 3.10 (95% CI, 1.98-4.86), P < .00 001, I2 = 14%). Overall, complications occurred in 5.84% of the patients with 0.34% revision rate. Complication events in MF was lower compared to FH (OR 0.47 (95% CI, 0.10-2.15), P = .33, I2 = 0%). Conclusions: Meta-analysis shows that MF is more accurate than FH in pediatric and adolescent requiring PS placement for spinal fusion surgery.

“…Sin embargo, este tipo de métodos combinados para la detección de diferentes patologías no suele desarrollarse [28], [51] y los que existen suelen centrarse en clasificar el disco únicamente como normal o anormal. Otra limitación es la ausencia de un patrón de referencia, sólo obtenido en cadáveres [55], [56]. Para poder evaluar la validez de los sistemas desarrollados es necesario disponer de una referencia con la que compararlos.…”
