About

Yu-Tzu Chang is a leading orthopedic researcher whose work centers on minimally invasive spine surgery, with a particular focus on osteoporotic vertebral compression fractures. Her major contribution lies in advancing the evidence base for robot-assisted kyphoplasty, a procedure that restores vertebral height and alleviates pain in patients with collapsed vertebrae. In her landmark 2023 meta-analysis, which has already garnered 8 citations, Chang systematically compared robot-assisted (RA) kyphoplasty with traditional fluoroscopy-assisted techniques, demonstrating that robotic guidance significantly improves pedicle screw placement accuracy and reduces radiation exposure. This work has helped establish RA-PKP as a safer, more precise alternative for treating the most common manifestation of osteoporosis. Chang’s research bridges the gap between emerging surgical robotics and clinical outcomes, offering spine surgeons a data-driven rationale for adopting these technologies. Her findings are particularly impactful for an aging global population, where vertebral fractures are a leading cause of morbidity. By quantifying the benefits of robotic assistance, Chang has not only advanced surgical practice but also laid the groundwork for future studies on automation in spine surgery.
