... Spinal instrumentation is commonly used to stabilize the multi-level strut- grafted cervical spine. There are no standard tissue-based testing protocols for evaluating spinal devices. An improved biomechanical testing protocol was developed to study the strut-graft mechanics of the instrumented...

... The cervical spine serves two primary functions: (1) as a mechanical linkage that allows a large controlled range of head motions and (2) as a protective structure for the spinal cord that passes through the spinal canals of the vertebrae. Cervical injuries involving fracture or dislocation...

... The catastrophic nature of cervical spine injuries in football, although the incidence of these injuries is infrequent, has led to recent attempts to develop new methods of neck protection. Currently, no performance standards or test standards exist for neck protection equipment to assure...

... Axial compression of the cervical spine is a significant source of spinal cord trauma and quadriplegia. This paper summarizes a number of studies related to injury mechanisms and potential strategies for reducing the risk of trauma. Head first collisions at 1.8 m.s -1 were conducted...

... We present a two part study. The first part deals with the mechanics of cervical spine injury and the injury mechanism. We have established the parameters of a head first impact situation which gives rise to catastrophic cervical spine injuries. We have examined the parameters of head...

... stiffness in axial compression-tension, antero-posterior and lateral shears, and flexural rotations (flexion-extension and lateral bending). Buckling modal analysis of this model estimated the potential responses of the cervical spine subjected to “axial” head impact. The calculated theoretical buckling...

... Compression related mechanisms of injury are common in sports and recreational trauma to the human cervical spine. The purpose of these studies was to experimentally reproduce common clinically seen injuries of the head-neck complex. A total of 19 preparations (8 quasistatic, 11 dynamic) were...

... The motion of the head and neck until injury, or the threshold of injury is normally limited by the tension of soft tissues along the cervical spine and by any obstruction. The relative range of motion (ROM) available during loading until injury is dependent partially upon the initial starting...

... Cervical spine fractures, particularly of the burst type, caused by axial compressive loading of the spine, have been an increasing problem in hockey for the past several years. The mechanism associated with such injuries involves a headfirst collision in which the crown of the head strikes...
