About

Zhaojie Liu is an orthopedic surgeon and researcher whose work sits at the cutting edge of robot-assisted minimally invasive surgery for complex pelvic and spinal trauma. His research focuses primarily on the application of robotic guidance systems — particularly the TiRobot platform — to challenging procedures including lumbopelvic fixation, sacroiliac screw placement, triangular osteosynthesis, and acetabular fracture repair. Liu's most cited work, a 2021 study on robot-aided treatment of traumatic spinopelvic dissociation (32 citations), demonstrated that robotic assistance can improve surgical precision and safety in one of orthopedic trauma's most technically demanding scenarios. Subsequent studies have extended this approach to vertically unstable sacrum fractures, osteoporotic sacral fractures, and fragility fractures of the pelvis — injury types disproportionately affecting elderly patients where minimally invasive techniques are especially valuable. Collectively accumulating over 65 citations, Liu's body of work makes a consistent evidence-based case that robotic assistance reduces operative risk, improves screw placement accuracy, and enhances patient outcomes compared to conventional methods. His contributions are shaping a new standard of care in percutaneous pelvic and lumbosacral fixation surgery.
