Injury to the carotid artery can occur in athletes by direct blow to the neck or by hyperextension of the neck. After such injury, symptoms may be mild or transient. Catastrophic complications such as stroke can occur if the injury is not recognized and treated. Neurologic changes such as transient weakness or transient unilateral blurred vision that occur after a hyperextension injury or a dir...

CONTEXT Motor vehicle (MV)-related injury is a leading cause of death and emergency department visits in the US. Information has been limited regarding the magnitude and types of injuries suffered by the survivors of MV crashes. OBJECTIVE To estimate the incidence and patterns of neck strain/sprain injury among MV occupants treated in US hospital emergency departments. DESIGN AND PARTICIPAN...

OBJECTIVE The neck injury index, NII, developed in ISO 13232 (2005) as a testing and evaluation procedure for assessing the risk of injury to the AO/C1/C2 region of the cervical spine in motorcycle riders is reevaluated using an existing postmortem human subjects (PMHS) data set and resulting in a reformulated NII criterion applicable to PMHS tests. METHODS A recent series of 36 PMHS head/nec...

BACKGROUND The incidence of femoral neck and trochanteric fractures reportedly differ by age and regionality. We investigated differences in monthly variations of the occurrence of femoral neck and trochanteric fractures as well as place and cause of injury in the Kyoto prefecture over a 6-year period. METHODS Fracture type (neck or trochanteric fracture), age, sex, place of injury, and cause...

BACKGROUND The role of routine dedicated spinal imaging and immobilisation following gunshot wounds (GSW) to the head, neck or torso has been debated. The purpose of this study was to determine the incidence of spinal column injury requiring stabilisation in evaluable patients following gunshot injury. METHODS A retrospective study from of a Level I trauma centre from January 1995 to December...

BACKGROUND The prevention of head injuries in alpine activities has focused on helmets. However, no systematic review has examined the effect of helmets on head and neck injuries among skiers and snowboarders. METHODS We searched electronic databases, conference proceedings and reference lists using a combination of the key words "head injury or head trauma," "helmet" and "skiing or snowboard...

The objective of this research is to develop neck injury criteria and injury tolerance levels to be used as a basis for a performance standard for the certification of side facing aircraft seats. This paper presents the results of the first part of this study. A literature review was performed on the neck injuries, kinematics and injury mechanisms in lateral loading and existing injury criteria...

Despite a large number of rear-end collisions on the road and a high frequency of whiplash injuries reported, the mechanism of whiplash injuries is not completely understood. One of the reasons is that the injury is not necessarily accompanied by obvious tissue damage detectable by X-ray or MRI. An extensive series of biomechanics studies, including injury epidemiology, neck kinematics, facet c...

Cervical sprain syndrome is usually the result of a hyperextension injury of the neck; symptoms include neck, intrascapular and arm pain, and headache. Associated complaints of the head, neck, and upper extremities are common. The mechanism and pathophysiology of this injury, and the occurrence of associated injuries are discussed. Patient evaluation, treatment, and prognosis are reviewed. A th...
