Findings demonstrate that improved screw placement lowers reoperation rates due to adjacent segment disease in older adults, suggesting better surgical practices.
Our findings indicate that optimizing pedicle screw positioning-specifically maintaining a PS tip-VE distance of at least 7.5% and a PS-VE angle below 10°-can significantly reduce reoperation rates due to ASD in patients over 55. Implementing these specific parameters in surgical practice may lead to improved patient outcomes and reduced incidence of ASD-related interventions.
