Cervical spine trauma is one of the most serious injuries of the human musculoskeletal system, as structural disorders of the cervical spine lead to neurological disorders due to damage to the spinal cord and/or its roots or create conditions when instability poses a significant potential threat to anatomical integrity and functional capacity of the spinal canal structures. A lot of classifications of traumatic injuries of the cervical spine have been developed, they are based on the biomechanics of injury, but none of them is generally accepted and universal. Failures to develop a system that could clearly determine the causal relationship between the effects of the traumatic agent and the traumatic bone changes are due to a number of causes. Extensive clinical material accumulated over the years of study of traumatic changes in the cervical spine allowed identifying the main criteria that determine the nature and degree of traumatic injuries. These include the parameters of traumatic action and individual characteristics of the victims, in particular physiological indicators and the presence of comorbidities. In this review, we present a brief description of the main clinical factors influencing the biomechanics of traumatic cervical spine injury (nature, direction and intensity of traumatic action, age of a patient, muscle condition and initial curvature of the cervical spine, as well as some comorbidities: degenerative changes of the spine, osteoporosis, connective tissue diseases, congenital malformations). These criteria are of practical importance that allows using the collected information not only in theoretical but also in applied aspects.

“…Engineering-based investigations of MVCs have focused on preventing or reducing the incidence of injury through the modification of the vehicle, including, but not limited to, energy-absorbing seat designs and head-restraint geometry. 59,60 Collectively, these studies involving biofidelic dummies, human cadavers, and human volunteers have shown that the total movement of the head and neck, spanning 200 milliseconds during a typical rear-end vector impact, largely remains within physiologic limits, 96 but abnormal movements occur within individual segments at upper and lower cervical levels. 49 This abnormal movement is referred to as the "S-shape" phase of neck motion (FIGURE 1), which consists of flexion at the upper spinal levels and extension at the lower levels, and can exceed physiologic limits and potentially induce subfailure injuries to a number of tissues (facet joints and capsules, the intervertebral disc, ligaments, vascular tissues, osseous structures).…”

STUDY DESIGN Non-systematic review of cervical spine lesions in whiplash-associated disorders (WAD). OBJECTIVE To describe whiplash injury models in terms of basic and clinical science, to summarize what can and cannot be explained by injury models, and to highlight future research areas to better understand the role of tissue damage in WAD. SUMMARY OF BACKGROUND DATA The frequent lack of detectable tissue damage has raised questions about whether tissue damage is necessary for WAD and what role it plays in the clinical context of WAD. METHODS Non-systematic review. RESULTS Lesions of various tissues have been documented by numerous investigations conducted in animals, cadavers, healthy volunteers and patients. Most lesions are undetected by imaging techniques. For zygapophysial (facet) joints, lesions have been predicted by bioengineering studies and validated through animal studies; for zygapophysial joint pain, a valid diagnostic test and a proven treatment are available. Lesions of dorsal root ganglia, discs, ligaments, muscles and vertebral artery have been documented in biomechanical and autopsy studies, but no valid diagnostic test is available to assess their clinical relevance. The proportion of WAD patients in whom a persistent lesion is the major determinant of ongoing symptoms is unknown. Psychosocial factors, stress reactions and generalized hyperalgesia have also been shown to predict WAD outcomes. CONCLUSION There is evidence supporting a lesion-based model in WAD. Lack of macroscopically identifiable tissue damage does not rule out the presence of painful lesions. The best available evidence concerns zygapophysial joint pain. The clinical relevance of other lesions needs to be addressed by future research.
