Cervical spinal column injuries secondary to vehicular crashes can be severe and costly to the individual and to the society as a whole. Injuries involve bony damage in the form of fractures with or without dislocations and/or soft tissue ruptures such as intervertebral disc disruption and ligament tear. Our understanding of the mechanism and the biomechanics associated with these injuries comes from an analysis of epidemiological, clinical and experimental research [ 1,4,6-11, 14, 17]. Epidemiological studies have classified these injuries in a vehicular environment based on factors such as incidence, type of impact and occupant seating location. Databases such as the National Automotive Sampling System and Fatality Analysis Reporting System have been traditionally used to further analyze injuries. Clinical studies have included the retrospective evaluation ofthe patient using modalities such as radiography, computed tomography and magnetic resonance imaging. These studies can provide important information regarding the physiological and anatomical status of the patient, and the determination of the mechanisms of injury on a retrospective basis. However, from these studies it is difficult to quantify the actual load vector responsible for the production of the injury and the associated biomechanical variables. Depending on the extent and severity of the external load vector applied during the crash event, different types of injuries can occur to the human neck structure. Commonly encountered cervical injuries are classified into noncontact related (inertial loading) and contact related (with head impact) trauma. For example, cervical spine injuries resulting from a low speed, rear-end vehicular-collision caused by inertial loading are often considered to be of the noncontact type. In contrast, injuries arising from contact of the human head with the vehicular interior or the exterior surfaces belong to the contact category. Bony damage such as burst and wedge fractures associated with the disruption of the posterior ligaments are typical examples of contact induced neck injuries in a motor vehicle environment. This paper focuses on the correlation between the loading mechanisms and biomechanical quantities associated with cervical spine injury due to head impact.
