DOI: 10.1177/21925682211018467

Abstract: STUDY DESIGN A finite element analysis study. OBJECTIVE Of proximal junctional failure, upper instrumented vertebra (UIV) fracture can causes severe spinal cord injury. Previously, we reported that higher occupancy rate of pedicle screw (ORPS) at… read more here.
