STUDY DESIGN Biomechanical finite element models simulated deformity correction using pedicle screw instrumentation and measured forces at the screw-vertebra interface. OBJECTIVES Compare 2 different screw designs with respect to reaction forces at screw-vertebra interfaces during scoliosis correction maneuvers. SUMMARY OF BACKGROUND DATA Pedicle screw(More)
STUDY DESIGN A biomechanical spine model was used to evaluate the impact of screw design on screw-vertebra interface loading during simulated surgical corrections of adult scoliosis. OBJECTIVES To evaluate differences in screw-vertebra interface forces during adult scoliosis correction between favored angle (FA) screws with extension tabs and standard(More)
