The motions and mechanics of the spine are quite complex. Knowledge of spine biomechanics can provide insight into the function of the healthy spine and the impact of spine pathologies (e.g. disc degeneration). Understanding natural spine mechanics also informs surgical practice and the design of implants to improve patient outcomes.

The Computational Biomechanics lab has developed finite element models of the lumbar and cervical spine to address a variety of clinically relevant questions. Models are calibrated to in-vitro spine test data using a sequential transection protocol to allow each structure to be properly represented. Modeling efforts have emphasized computational efficiency.  Analyses have been performed to investigate the behavior of the spine after the addition of spinal implants, such as posterior stabilization devices (fusion and semi-fusion devices), artificial discs, and total disc replacement implants.
