About

Seung-Jae Hyun is a leading spine surgeon and researcher whose work centers on advancing minimally invasive spinal instrumentation and reducing occupational radiation exposure in the operating room. His most impactful contribution is a landmark prospective randomized clinical trial comparing minimally invasive robotic-guided versus open fluoroscopic-guided spinal fusions, which demonstrated that robotic assistance can significantly improve screw placement accuracy and reduce complications. This study, with over 300 citations, has helped establish robotic guidance as a viable alternative to traditional fluoroscopy in complex lumbar fusions. Hyun has also made critical contributions to radiation safety, quantifying the real-world effectiveness of lead aprons in blocking X-rays during spine surgeries—a study that has influenced protective protocols worldwide. Additionally, he has pioneered techniques for S2 alar iliac screw placement under robotic guidance in adult spinal deformity patients, expanding the applications of robotic surgery in challenging cases. With a career focused on merging technological innovation with clinical precision, Hyun’s work continues to shape safer, more effective surgical practices in spinal care.
