Comparison of pedicle screw loosening under uniaxial and multiaxial loading
This study demonstrated that physiologically-derived multiaxial loading accelerates volumetric bone damage and pedicle screw loosening. Further, the increased bone deformation in the medial and lateral directions suggests that spinal movements involving these loads may accelerate risk of screw loosening.
