About

Yen-Jen Chen is a leading orthopedic researcher whose work centers on advancing spinal deformity surgery through innovative 3D printing and navigation technologies. His most-cited study, "The Accuracy of 3D Printing Assistance in the Spinal Deformity Surgery" (2019), with 36 citations, directly addresses a critical challenge in the field: improving pedicle screw placement accuracy while overcoming the prohibitive costs and spatial constraints of robotic and navigated systems. Chen’s major contribution lies in demonstrating that patient-specific 3D-printed guides can achieve superior screw placement precision comparable to high-end robotic assistance, but at a fraction of the cost and complexity. This work has significant implications for making advanced spinal deformity correction more accessible in resource-limited settings. By systematically comparing 3D printing assistance to free-hand and fluoroscopy-guided techniques, Chen provided compelling evidence for a practical, cost-effective alternative that maintains surgical safety and efficacy. His research bridges the gap between cutting-edge technology and real-world clinical applicability, offering a scalable solution that could transform standard practice in spinal surgery. Chen’s findings continue to influence surgical planning and instrument design, marking him as a key innovator in orthopedic biomechanics and precision medicine.
