Biomechanical Impact of Cement Augmentation on Pedicle Screw Fixation and Adjacent Segment Disease in Multilevel Lumbar Fusion: A Finite Element Analysis
Cement augmentation effectively improves screw fixation and does not appear to significantly increase ASD risk based on this FEA study. Limiting cement augmentation to the UIV level in lumbar multilevel fusion may help reduce the risk of implant failure, though further clinical validation is required to confirm these biomechanical findings.
