Neurosurgical focus: Video最新文献

The clinical use of new technologies has the goal to produce healthcare advancements. In this context, robotic assistance for spinal surgery carries several potential benefits, including improved accuracy, precision, and efficiency, and such technology is making its way into neurosurgical operating rooms with increasing frequency. However, shifting the spinal fusion technique from the traditional freehand C-arm-guided technique to a robot-assisted technique can be challenging. In this video, the authors present the step-by-step robot-assisted technique, using the Mazor X Stealth robotic technology, as performed in their department for lumbar pedicle screw placement.

Robot-assisted S2-alar-iliac (S2AI) screw placement enhances accuracy and minimizes complications in spinal deformity and pelvic fixation surgeries. This video outlines the intraoperative navigation, planning, and execution of S2AI screw placement using robotic guidance. By optimizing screw trajectory and reducing soft-tissue disruption, robotic assistance improves biomechanical stability in long-segment spinopelvic constructs. The integration of real-time navigation enhances precision, potentially lowering revision rates. This video aims to highlight the technical nuances, clinical advantages, and outcomes associated with robot-assisted S2AI screw placement, underscoring its role in advancing spine surgery with greater consistency and safety.

The integration of robot-assisted spine surgery (RASS) and single lateral position surgery (SLPS) has revolutionized spinal fusion by enhancing efficiency, reducing surgical time, and improving patient outcomes. This video demonstrates a step-by-step procedural workflow for robot-assisted OLIF L4-L5, ALIF L5-S1, and percutaneous pedicle screw fixation (L4-S1) in a single lateral decubitus position using the ExcelsiusGPS system. The workflow highlights preoperative CT-based planning, intraoperative image fusion, real-time navigation, and robot-guided implant placement. SLPS eliminates the need for patient repositioning, reduces anesthesia duration, and enhances operating room efficiency, showcasing the role of robotics and innovative positioning strategies in modern spine surgery.

A 50-year-old male with grade I spondylolisthesis at L5-S1 was treated surgically with a robotic anterior lumbar interbody fusion (R-ALIF). A general surgeon used the da Vinci robotic system to access the disc space and indocyanine green to visualize the vessels including the aortic bifurcation and middle sacral artery. A neurosurgeon completed the discectomy and fusion through a suprapubic GelPOINT Mini. R-ALIF combined with robotic percutaneous pedicle screw fixation resulted in no significant complications, minimal blood loss, a 4-hour surgical time, reduced patient-reported pain, and adequate cage placement.

This video demonstrates the robot-navigated minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) technique for spondylolisthesis. Navigation and robotics enhance accuracy in pedicle screw placement, reduce operative time and radiation exposure, and improve patient recovery. The case of a 70-year-old patient with L4-5 spondylolisthesis and spinal stenosis is presented. Key surgical steps include intraoperative imaging, preoperative planning, robot-guided screw placement, targeted decompression, and interbody cage implantation. The workflow optimizes safety and efficiency while minimizing tissue disruption. Postoperative imaging confirms precise implant positioning and spondylolisthesis correction, demonstrating how robotics and navigation contribute to superior surgical precision, reproducibility, and improved clinical outcomes.

Lumbar spondylolisthesis can lead to symptoms of mechanical back pain and radiculopathy. Surgical treatment aims to address dynamic instability and foraminal stenoses. While various alternatives exist to treat this clinical presentation, the single-position prone lateral interbody fusion has recently emerged as a popular technique. This operative video illustrates the treatment of a grade 1 L3-4 spondylolisthesis with a single-position prone lateral transpsoas interbody fusion with percutaneous instrumentation using the Mazor X Stealth robotic system. Detailed step-by-step techniques with operative pearls are provided to help surgeons incorporate the nuances of robotic navigation to the single-position prone lateral procedure.

The authors describe the case of a patient with lumbar stenosis and neurogenic claudication who underwent a robot-assisted total posterior arthroplasty (TOPS [Total Posterior Spine] System) procedure. The TOPS is a motion-preserving implant that replaces the facet joints, allowing a wider decompression (when compared with laminectomy) and normal postoperative range of motion (as opposed to fusion), decreasing the risk of adjacent segment degeneration and the need for surgery in the future. The robot allows for precise placement of preplanned pedicle screws, allowing for accurate intraoperative device placement and decreased operative time. This patient returned to an active lifestyle without complications. The video can be found here: https://stream.cadmore.media/r10.3171/2025.4.FOCVID2517.

This video demonstrates robotic assistance for performing single-position prone lateral transpsoas interbody fusion with posterior percutaneous screws. The ability to preoperatively plan the screws and interbody devices may help surgeons improve accuracy as well as increase the ease of performing these single-position minimally invasive procedures.

Robotic navigation has primarily been used for instrumentation in the thoracic and lumbar spine. The cervical spine, on the other hand, is a less common site for robot-assisted screw placement. Furthermore, the anatomical complexity and presence of adjacent vascular structures in this region necessitates high placement accuracy. This operative video illustrates the placement of C1 lateral mass and C2 pars screws for a posterior C1-2 fusion using the ExcelsiusGPS surgical robot in a patient with spinal cord compression secondary to a retro-odontoid pannus.

Robotic spine surgery is a rapidly developing field and offers several advantages for both patients and the surgical team. Several studies have shown greater accuracy in screw placement, less blood loss, less radiation exposure, and fewer reoperations compared with freehand procedures. Here the authors present the case of a 40-year-old woman with a herniated disc at level L4-5 and spondylolysis at level L5-S1. They performed robot-assisted spondylodesis using midline cortical screws in both levels due to foot-drop paralysis and refractory pain and present their workflow for robot-assisted spondylodesis.
