Biomechanical insights into anterolateral vertebral screw fixation in osteoporotic spines: a comparative study of fixation methods and positions using porcine vertebrae
Bicortical fixation exhibited significantly greater pullout forces than unicortical fixation. We suggest positioning screws in the central or posterior region of the middle body with bicortical fixation in osteoporotic vertebrae.
