Finite Element Analysis Of The Cervical Stability after Ligamentous Injuries

Introduction The cervical spine is often subjected to many types of loading during daily activities. Stability of the cervical spine is provided by ligaments, facet joints, muscles and disc, which restrict the range of movement. Many biomechanical studies on the injured and stabilized cervical spine have already been carried out by other authors . There are also finite element analyses of the cervical spine instability due to facetectomy and laminectomy to provide further understanding . However, the contribution of ligaments to cervical spine stability has not been clearly established. Ligaments provide stability to the cervical spine motion and thus, an important part of cervical spine research. Ligamentous injuries will decrease the mechanical stiffness the cervical spine, and potentially affecting other spinal components. It is clear that a cervical motion segment is unstable if it exhibits abnormally large displacements in terms of either rotational or translational movements under physiological load levels.
