About

Kosei Nagata is a spine surgeon and researcher whose work focuses on improving the safety and precision of robotic-assisted spinal surgery, particularly through the use of cortical bone trajectory (CBT) screw fixation. His primary research areas include surgical technique optimization, screw insertion biomechanics, and the identification of risk factors for intraoperative complications in minimally invasive spine surgery. Nagata’s major contributions center on characterizing the causes of screw malposition—such as skive and shift—during robot-assisted procedures. His 2023 study, which has garnered 5 citations, is a landmark retrospective analysis that systematically identifies risk factors for screw malposition, providing actionable insights for surgeons to reduce medial breach and improve patient outcomes. His subsequent 2024 work further refines these findings by comparing no-tap (two-step) versus tapping techniques, offering evidence-based guidance for surgical practice. With a growing citation impact, Nagata’s research is highly relevant for spine surgeons and engineers developing robotic systems, as it bridges the gap between technological capability and clinical safety. His meticulous approach to studying intraoperative errors positions him as a key voice in advancing the reliability of robotic-assisted spine surgery.
