A dynamic reference frame (DRF, tracker) was installed on a spinous process. Then, the first 3D scan was acquired, and images of each section were recorded. The 3D images were reconstructed and then transferred to the navigation station (StealthStation S7 Navigation System; Medtronic, Minneapolis, MN, USA). Under the guiding of navigation, the entry point and trajectory were designed. An awl was used to make the entry and the pedicle tract was made with a probe. By a navigated screwdriver, the pedicle screw was placed to a proper depth. The position and screw trajectory were displayed on the monitor [36 (link)] (Fig.1 ).

For iCT- and rCBCT-based spinal navigation, the AIRO iCT (Brainlab AG, Munich, Germany) and robotic 3D Artis Zeego II digital fluoroscopy C-arm system (Siemens Healthcare, Forchheim, Germany) were used as previously described25 (link),31 (link),32 (link). For CBCT-based spinal navigation, the mobile O-arm system (Medtronic plc, Dublin, Ireland) was used. For navigated pedicle screw implantation, an image-guidance system and infrared tracking camera with automatic patient/image co-registration was used (iCT and rCBCT: Brainlab Curve and Brainlab Spinal Navigation Software Version 3.0, Brainlab AG, Munich, Germany; CBCT: Stealth Station S7 Navigation System, Medtronic plc, Dublin, Ireland)28 (link).

All surgical procedures were performed by the same spine surgeon. Patients were placed in the prone position during PSF with instrumentation. Generally, two titanium PS were employed per vertebral level, however, if the surgeon considered the pedicle too small or fragile, the insertion could be skipped or PS could be replaced by hooks. Before insertion of the PS, the inferior and superior articular processes within the to-be-fixed range were resected. The hybrid OR encompassed a radiolucent Magnus Operating Table System (Maquet, Rastat, Germany) and a StealthStation ® S7 ® navigation system (Medtronic, Memphis, TN, USA; Figures 1C and1D). Surgical navigation was performed using surface registration based on the intraoperative CBCT images (L-group; see Video 1 for 3D reconstruction) or the preoperative CT images (M-group; Figure 3A).

After initial sedation, the patient was co-registered to the Medtronic StealthStation S7 Navigation system (Fig. 2C), which was used to guide craniotomy locations (Fig. 2E) and provide an initial assessment of the preoperative implant targets relative to the underlying cortical anatomy. The central sulcus was localized by performing intraoperative neurophysiologic monitoring (IONM). A 1x8 ECoG strip was placed perpendicular to putative central sulcus, and phase reversal of the evoked potentials was recorded during median nerve stimulation according to established clinical protocol (Fig. 2F).

After midline exposure, the reference frame was fixed to the spinous process, and the binocular infrared camera were adjusted to receive the reflector ball. The first 3D scan was acquired in 13 s, and the intraoperative 3D images were then automatically obtained and visualized on O-arm viewing station (Stealth Station S7 Navigation System; Medtronic, Minneapolis, MN, USA). With the guidance of virtual navigation images, pedicle screws were routinely placed after verifying the integrity of medial wall. Once all screws have been placed, a second intraoperative 3D scan with O-arm were conducted to confirm whether they were in the target position.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
