Robotic Guidance Improves Pedicle Screw Placement Accuracy during precision spinal surgery: Study
Researchers have found in a new study that Robotic-guided pedicle screw fixation is a safe and highly effective technique that demonstrates significantly greater screw-placement accuracy than CT-guided navigation, supporting its use in precision spinal surgery.
Spondylodesis is performed to stabilize and immobilize spinal regions impacted by conditions such as degenerative disorders, deformities, trauma, tumors, or infections. To improve the accuracy of pedicle screw placement, computer-assisted navigation systems were introduced in spine surgery. The objective of this study was to compare the accuracy of pedicle screw placement and the patient outcomes in robotic-guided versus intraoperative 3D navigation techniques for thoraco-lumbar spine surgery.
The search was conducted on 30 September 2025 on Scopus, Cochrane Central Library and PubMed. Prospective and retrospective studies that compared pedicle screw placement, clinical outcomes and complications using robotic versus intraoperative 3D navigation technique in the thoracolumbar segment were included. Hospital stay, operative time and blood loss were evaluated as continuous outcomes with mean difference. Screw accuracy, FJV, intraoperative and postoperative screw revisions, complications and complications were evaluated as dichotomous outcomes with odds ratio. Statistical significance was set at p < 0.05.
Among the 14 studies included in the meta-analysis, statistically significant results in favor of robotic group were described for hospital stay (p = 0.003) and pedicle screw accuracy (p < 0.00001). However, no significant differences were observed in terms of intraoperative or postoperative screw revisions, facet joint violations, operative time and blood loss.
Robotic-guided pedicle screw fixation represents a safe and highly effective technique, showing statistically significant superiority in screw placement accuracy compared to CT-guided navigation.
