Probabalistic Response of a Validated And Verified Parametric Cervical Spine Finite Element Model

This biomechanics paper develops a probabilistic finite element model of the cervical spine, accounting for variability in soft tissue properties and geometry. The FE model's mesh was robustly generated using Truegrid preprocessing software for accurate geometric representation. By incorporating uncertainty and leveraging FEA, the model provides a more realistic prediction of injury probability, enhancing the understanding of spinal injury biomechanics for risk assessment.
