Abstract
- Clinical finite element model of the human lumbosacral spine and its applications
- Patient-specific models for pediatric head injury
A clinical applicable three-dimensional model was developed and fully validated against the in-house in vitro experimental data. This model has been implemented to quantify the intersegmental motions and internal responses of lumbosacral spine after the commonly used surgical techniques (interbody fusion, facetectomy). Currently the model is being utilized to investigate the effect of total disc replacement on motion and stress in spine.
The impact response of a pediatric patient’s head is intrinsically linked to the geometry and mechanical properties under a known traumatic loading. Finite element models including cranial bone of skull, brain, and suture were generated. Both static and dynamic analysis was performed to verify the models.
