About

Nader Toossi is a spine surgery researcher whose work sits at the intersection of surgical robotics, spinal instrumentation, and patient safety. His research focuses primarily on the accuracy and optimization of robot-assisted pedicle screw placement, a technically demanding procedure critical to spinal stabilization and fusion surgeries. Through rigorous retrospective analyses and multicenter studies, Toossi has systematically investigated the factors influencing screw placement precision, evaluated system-specific robotic platforms such as the ExcelsiusGPS, and explored how robotic guidance can reduce misplacement rates—particularly in the challenging thoracic spine, where smaller pedicle diameters increase procedural risk. His work has demonstrated that robotic assistance not only improves accuracy but also enables surgeons to utilize larger pedicle screw sizes while maintaining elevated safety margins, as evidenced by triggered electromyographic threshold data. Collectively, his publications have accumulated over 50 citations, reflecting meaningful uptake within the spine surgery community. Toossi's contributions provide clinicians with valuable, evidence-based insights into when and how robotic systems can most effectively enhance surgical outcomes, making his work an important reference for surgeons and researchers navigating the rapidly evolving landscape of technology-assisted spine care.
