About

Yoshiharu Nakaya is a spine surgeon and researcher whose work centers on advancing the precision and safety of spinal instrumentation, with a particular focus on pedicle screw placement technologies. His research has made meaningful contributions to the growing field of robotic and image-guided spine surgery, rigorously evaluating how these systems perform in real-world and cadaveric settings. Nakaya's most influential work, "Accuracy of Pedicle Screw Placement with Robotic Guidance System" (2015), has accumulated 42 citations and remains a foundational reference in the field, demonstrating through cadaveric investigation that robotic guidance systems can achieve reliable screw placement accuracy. His more recent investigations, published in 2024, extend this inquiry to the technically demanding domain of cervical pedicle screw placement — one of the highest-risk procedures in spine surgery — comparing robotic guidance directly against image guidance systems using rigorous propensity score matching methodology. Taken together, Nakaya's body of work reflects a sustained commitment to evidence-based evaluation of surgical technology, helping clinicians make informed decisions about adopting robotic platforms. His research is particularly valuable for trainees and practicing spine surgeons seeking to understand the comparative strengths of emerging guidance technologies in complex spinal procedures.
