About

Shi Chang Liu is a leading orthopedic spine surgeon whose research focuses on advancing surgical precision and outcomes in complex spinal deformities, particularly adult degenerative scoliosis. His major contributions center on the comparative evaluation of assisted technologies for pedicle screw fixation. In his highly cited 2018 study (167 citations), Liu demonstrated that robot-assisted pedicle screw placement significantly outperforms the free-hand fluoroscopy-guided method in accuracy, establishing a new benchmark for minimally invasive spine surgery. He further expanded this work in a 2018 study (81 citations) comparing three assisted technologies—robotic, navigation, and conventional—in adult degenerative scoliosis, providing critical evidence that robotic guidance reduces screw malposition rates and improves clinical outcomes. Liu also pioneered a novel technique combining gelatin sponge impregnated with a three-drug mixture for intraoperative nerve root block with robot-assisted transforaminal lumbar interbody fusion, showing enhanced pain control and recovery in a 96-patient cohort. With over 260 total citations, Liu’s research is instrumental in shaping evidence-based protocols for robotic spine surgery, offering surgeons and students a clear roadmap for integrating technology to improve patient safety and surgical efficacy.
