Title Biomechanics of whiplash injury and its influence on cervical spine structures Objectives: Objective of the work is charting of studies examining mechanism and course whiplash event, its influence on osseous and arthral textures, intervertebral discus, ligaments, neural textures, cerebro-spinal fluid and vertebral artery. In summary form mention possibilities of prevention in terms ofconstruction car. Method: Diploma work is processed in the form of commented literary background research. Results: Confrontation of individua! works brought definite results, respecting kinematics cervical spine at rear impact. Most ofin vivo and in vitro studies confirmed clear two-phase answer. Immediately after stroke (50 - 110 msec) cervical spine is forming S-form deformation with flection UCS and extension LCS, whereas it is extension with abnormal JAR. Whole spine is loaded by compression at this time. The second period is C-form deformation with extension whole cervical spine. Risk of structures injury is the highest in S- stage. The most often it is localized in LCS, and it is in intervertebral joints including capsular ligaments, intervertebral discus and anterior longitudinale ligament. There are threatened also neural textures, both influence oftension force applied to UCS, and pressurized gradient...
