Zhen Chang

About

Dr. Zhen Chang is a pioneering orthopedic surgeon whose research focuses on the precision and safety of spinal surgery, particularly through the comparative evaluation of advanced navigation and robotic systems. His major contributions lie in rigorously assessing the clinical efficacy of the TINAVI orthopaedic robot against traditional open surgery and other navigation technologies for complex spinal conditions. Notably, his 2023 study on Levine–Edward type IIA hangman fractures demonstrated that robot-assisted percutaneous pedicle screw fixation offers significant advantages over conventional open surgery, a finding that has garnered 10 citations. Dr. Chang has further advanced the field by comparing the TINAVI robot with the O-arm combined CT 3D real-time navigation system for adolescent congenital scoliosis (7 citations) and with the S8 navigation system for upper cervical instability (6 citations). Through these high-impact comparative studies, Dr. Chang is establishing evidence-based benchmarks for minimally invasive, robot-assisted spinal procedures, directly informing surgical decision-making and improving patient outcomes in challenging orthopedic cases.
