Serious Injuries

Pedestrians sustain serious injuries when impacted by vehicles [1]. Various biomechanical studies have focused on pedestrian injuries due to direct contact with the vehicle and environment [1–5]. Similar studies on the injuries to the pedestrian due to indirect force such as inertial load are limited [6]. One of the most susceptible regions of the human body to inertial loading is the neck component (cervical spine). The cervical spine connects the head and upper torso, and provides mobility to the head. Direct loading to the head and/or upper torso subjects the cervical spine to indirect loading. For example, in a pedestrian lateral fall on the shoulder, the cervical spine flexes laterally due to inertial loading from the head and upper torso, and may injure its soft tissue components. The purpose of this study is to delineate the biomechanics of the soft tissue neck injury during the pedestrian lateral fall due to vehicular impact using the anthropometric test device.

Type Of Injury

Unilateral facet injuries are relatively common in the sub-axial cervical spine. Facet fractures, capsular disruptions, and posterior ligament tears can all contribute to this type of injury resulting in a range of instability spanning undisplaced fractures to complete unilateral dislocations [1]. For a particular injury pattern, considerable variability exists in the choice of treatment, and the modality selected is frequently based on surgeon preference [2]. This is due, in part, to a lack of biomechanical studies focused on increasing the understanding of changes in spinal stability that occur following cervical spine injury.

Abstract [Background ]: To establish a three-dimensional finite element model of ossification of the posterior longitudinal ligament of the cervical spine with intervertebral fusion and verify its effectiveness, and provide a platform for finite element calculation and biomechanical analysis in the later stage.[Method]: Select the Department of Spinal Surgery, Linfen People's Hospital A volunteer imported 719 DICOM format images of cervical spine CT scans into Mimics modeling software to build a preliminary 3D model in the stl format, and used Geomagic Studio 2013 software to refine and refine the 3D model to smooth out noise and generate NURBS surfaces The model was then imported into the finite element analysis software Ansys workbench 15.0, adding ligaments and intervertebral discs, meshing, assigning material properties, and simulating 6 activities of the human cervical spine, and comparing them with references.[Results]: A total of 7 Cervical vertebral body, 1 thoracic vertebral body, 5 intervertebral discs and ligaments, etc., with a total of 320512 nodes and 180905 units. It has a realistic appearance, high degree of detail reduction, and ossification of the cervical longitudinal longitudinal ligament with good geometric similarity Incorporate a three-dimensional finite element model of intervertebral fusion. In flexion and extension, left and right lateral flexion, and axial rotation activity compared with references, there is not much difference.[Conclusion]: OPLL merger interbody fusion dimensional finite element model has good mechanical and geometric similarity after similarity cervical established in this study, the model can provide a platform for the latter to further biomechanical analysis.
