Abstract
A three-dimensional linear elastic FE analysis of six adjacent cervical vertebrae (C2- C7) has been developed. The model is composed of vertebrae and intervertebral discs. The objective of this research is to address the new advances in the generation of finite element meshes of the human cervical spine...
Highlights
The human spine is a complex structure that supports the weight of the body, transfer loads from the head and trunk to the pelvis and protects the spinal cord [1]
The model is composed of vertebrae and intervertebral discs
A procedure to create a finite element model based on available biomedical closed volumes obtained from computed tomography (CT) scans was introduced
Summary
The human spine is a complex structure that supports the weight of the body, transfer loads from the head and trunk to the pelvis and protects the spinal cord [1]. Cervical injury can be a result of extension, flexion, contusion, compression and rotation of the spinal cord. Traumatic accidents such as motor vehicle, sports, falls, overloading, etc., are the most frequent causes of cervical injuries. It is necessary to fully understand the biomechanical response of the cervical spine to external stimuli (injury and dysfunction). Biomechanical finite element models facilitate the understanding of the mechanisms of dysfunction, spinal injury, and spinal responses to various clinical problems and treatments. In earlier cervical spine models developed to predict only spinal motion or displacement response to loading, the vertebrae are simulated as simple rigid bodies, while other connective tissues are represented as beams, truss or spring elements
