About
Chih-Hui Chang is a pioneering spine surgeon whose research centers on robotic-assisted spinal surgery, particularly for challenging patient populations like those with osteoporosis. His most impactful work, with 76 citations, introduced a novel intraoperative classification system for evaluating pedicle screw placement accuracy using a bone-mounted miniature robot—the Renaissance system—through secondary registration. This contribution directly addressed the critical need for real-time precision feedback during minimally invasive procedures. Chang’s subsequent studies have focused on improving outcomes for osteoporosis patients, demonstrating that robotic assistance can reduce screw loosening and compression fractures in minimally invasive transforaminal lumbar interbody fusion. He has also explored the human factors of surgical innovation, quantitatively analyzing the learning curve for robotic spine surgery and highlighting the roles of teamwork and unmet needs in skill acquisition. With a career dedicated to merging engineering precision with clinical necessity, Chang’s work has established benchmarks for intraoperative accuracy and expanded the safety and efficacy of spinal robotics in fragile bone conditions, making him a key figure in advancing minimally invasive spine surgery for high-risk patients.
