Summary: This study evaluated the accuracy and safety of iCT-navigation for screw placement in revision thoracolumbar spinal surgery, comparing the virgin site and the revision site. The results showed that the rate of accepted screws at the revision site was comparable to that at the virgin site. Additionally, iCT-navigation allowed for the immediate revision of unaccepted screws.

Summary: The accuracy of cortical bone trajectory (CBT) screw placement guided by a spinous process clamp (SPC) guide was assessed in this study. Compared to the fluoroscopy-assisted free-hand (FH) technique, SPC-guided screw placement showed higher rates of clinically acceptable screw placement and lower rates of misplacement screws and proximal facet joint violation. It also had comparable radiation dose and time, but longer operative time. The clinical outcomes were similar between the two techniques.

Summary: The study investigated the safety and accuracy of a new self-guided pedicle tap for pedicle screw placement. The experiment was conducted on adult spine specimens using both conventional taps and the new self-guided pedicle taps. The results showed that the new tap achieved safe and accurate screw placement with a low-cost and convenient procedure, indicating its potential clinical value.

Summary: The TINAVI robot-assisted technique is associated with high accuracy in pedicle screw placement and a low rate of proximal facet joint violation (FJV). Factors such as female sex, BMI < 25.9, age < 61 years old, and facet angle >= 45 degrees are related to the accuracy of screw placement and proximal FJV.

Summary: The study developed an attachable magnetic nerve stimulating probe for intraoperative neuromonitoring during lumbar pedicle screw placement, showing no significant difference in the triggered threshold compared to conventional nerve probes. The newly developed magnetic stimulating probe can prevent real-time screw malpositioning and is practical and safe, potentially becoming indispensable in revision spine surgeries or endoscopic spine surgeries.

Summary: This research uses a novel automated measurement system to measure the accuracy of pedicle screw placement in spinal fusion surgery. The study found that the deviations measured by the automated system were statistically different from manually determined values, and also quantified the uncertainty associated with image fusion.

Summary: This study evaluated the accuracy of pedicle screw insertion in lumbar and thoracolumbar spinal fusion using a fully automated intraoperative ultrasound (iUS) navigation system. A total of 56 screws were inserted, with 52 screws inserted safely without breach. Four screws presented a medial breach with an average deviation of 1.35 +/- 0.37 mm (all <2 mm). The results demonstrate the feasibility and safety of the iUS navigation system for pedicle screw insertion in spinal fusion surgeries.

Summary: The study suggests that the use of iCT-Nav in spinal instrumentation surgery enables high-accuracy placement of pedicle screws and reduces the need for postoperative revisions. Male patients are less likely to experience high-grade pedicle breach, while lateral or anterior breach locations are predictive of high-grade breach.

Summary: This systematic review analyzed the accuracy of different methods for pedicle screw placement and found that robotic navigation is superior to other methods. Intraoperative 3D fluoroscopic navigation was found to have comparable accuracy. Moreover, the accuracy of robotic navigation has been improving over time.

Summary: This study compared the accuracy and clinical outcomes of robot-assisted and fluoroscopy-guided pedicle screw placement in posterior cervical surgery. The results showed that the robot-assisted group had higher success rate and accuracy, as well as less radiation time and dose, but longer operative time.

Summary: The study evaluates the accuracy of navigated, O-arm-controlled screw positioning in thoracic and lumbar spine instabilities. The results show that most of the pedicle screws were positioned accurately, with only a small number showing misplacement. Moreover, the combination of neuronavigation and 3D rotational fluoroscopy allows for reliable detection and revision of misplaced screws, reducing the need for repeat surgery.
