About

Dr. Changren Li is a leading orthopedic spine surgeon and researcher whose work centers on advancing surgical precision and patient safety in spinal instrumentation. His primary research areas include robot-assisted spine surgery, pedicle screw placement accuracy, and the reduction of intraoperative complications. Dr. Li’s most influential contribution is a landmark 2021 systematic review and meta-analysis comparing robot-assisted versus conventional fluoroscope-guided pedicle screw placement in the thoracolumbar spine. This study, which has garnered 20 citations, rigorously evaluated screw positioning accuracy, complication rates, revision frequency, and radiation exposure. By synthesizing evidence from multiple trials, Dr. Li provided crucial insights that help surgeons weigh the benefits of robotic assistance—such as improved accuracy and reduced radiation—against traditional methods. His work has directly informed clinical decision-making and the adoption of robotic technologies in spine surgery. Beyond this key paper, Dr. Li’s research portfolio continues to explore innovative approaches to minimize surgical risks and enhance patient outcomes. His contributions are widely recognized as foundational in the evolving field of computer-assisted orthopedic surgery, making him a respected voice in spine surgery research.
