Article Synopsis
- - This study evaluated the improvement in outcomes of robotic-assisted navigation (RAN) spine surgery as the surgeon's experience increased beyond 200 cases, focusing on operative time and the accuracy of pedicle screw placements.
- - A retrospective analysis of 60 patients divided into three groups showed that with each successive group, registration time, screw insertion time, and total operative time significantly decreased, while precision in screw placement improved from 87% to 98% as case numbers increased.
- - The study concluded that, although RAN spine surgery can be performed accurately from the start, outcomes significantly improve with increased surgical experience, highlighting the benefits of continued practice.
Background: Traditional minimally invasive fluoroscopy-based techniques for pedicle screw placement utilize guidance, which may require fluoroscopic shots. Computerized tomography (CT) navigation results in more accurate screw placement. Robotic surgery seeks to establish access and trajectory with greater accuracy.

Objective: The aim was to investigate the factors involved in, and their relative contributions to, the overall accuracy of robot-assisted pedicle screw placement.
Summary Of Background Data: Robot-assisted surgery has reportedly resulted in greater accuracy for placement of pedicle screws than conventional methods.
Computer-aided navigation and robotic guidance systems have become widespread in their utilization for spine surgery. A recent innovation combines these two advances, which theoretically provides accuracy in spinal screw placement. This study describes the cortical and pedicle screw accuracy for the first 54 cases where navigated robotic assistance was used in a surgical setting.

However, mainly for anterior circulation aneurysms, no clear superiority of these techniques compared with microsurgical clipping has been shown in terms of morbidity, mortality, aneurysm occlusion rate, and long-term protection from recanalization and rebleeding. We reviewed the data from a retrospective case series to determine the clinical and radiological outcomes of clipped ruptured and unruptured aneurysm to analyze the relationship between increasing surgical experience and operative time, recovery time, and clinical outcomes.

Methods: In 36 patients receiving 176 lumbosacral pedicle screws, EMG threshold to nerve root activation was determined using a focal probe inserted into the pilot hole at a depth, customized to the individual patients, suitable to position the stimulating tip at the point closest to the tested nerve root. Threshold to screw stimulation was also determined.
Objective: To verify the safety and clinical use of non-invasive high-voltage electrical stimulation (HVES) in patients with compressive radiculopathy. To test the feasibility of HVES to survey nerve root function during lumbosacral surgery.
Methods: In 20 patients undergoing lumbosacral surgery for degenerative spinal diseases, compound muscle action potentials (CMAPs) evoked by maximal HVES were bilaterally recorded throughout surgery from L3 to S2 radicular territories.
