The purpose of this study is to test the hypothesis that the upper cervical spine is weaker than the lower cervical spine in pure flexion and extension bending, which may explain the propensity for upper cervical spine injuries in airbag deployments. An additional objective is to evaluate the relative strength and flexibility of the upper and lower cervical spine in an effort to better understa...

in this study to determine whether spine stiffness is predictive of clinical results after lumbar spinal fusion for spinal stenosis, a total of 78 patients were measured intraoperatively with kocher clamp manual distraction technique to determine motion segment stiffness then spinal fusion was performed for any loose segment. ‎statistical analysis revealed that stiffness measurement correlate w...

OBJECTIVE To provide a foundation of knowledge concerning the functional anatomy, kinematic response, and mechanisms involved in axial-compression cervical spine injury as they relate to sport injury. DATA SOURCES We conducted literature searches through the Index Medicus, SPORT Discus, and PubMed databases and the Library of Congress from 1975-2003 using the key phrases cervical spine injury...

Spine involvement is less common in Reiter's syndrome than in other seronegative spondyloarthropathies. Also, cervical spine involvement rarely occurs in Reiter's syndrome and other spondyloarthropathies. This paper reports a rare case of Reiter's syndrome in which there was cervical spine involvement that presented clinically as an atlanto-axial rotatory subluxation. Reiter's Syndrome (RS) is ...

OBJECTIVE The objective of this study was to estimate the sensitivity of plain radiographs in identifying bony or ligamentous cervical spine injury in children. METHODS We identified a retrospective cohort of children younger than 16 years with blunt trauma-related bony or ligamentous cervical spine injury evaluated between 2000 and 2004 at 1 of 17 hospitals participating in the Pediatric Eme...

Cervical spine injury in pediatric trauma occurs rarely; however, there is significant potential for considerable morbidity when it does occur. Screening for cervical spine injuries has been shown to be most sensitive in adult trauma centers when combined with reliable physical examination findings. Because pediatric trauma patients suffer from a different range of injuries than adults, and oft...

PURPOSE To review the impact of concomitant cervical spine injury on the management of facial fractures in a tertiary care institution via a retrospective chart review. PATIENTS AND METHODS Within the past 10 years, 1,750 consecutive patients presented to our institution with facial fractures. Thirty-two had concomitant cervical spine injury. Five were transferred or died before treatment. Th...

BACKGROUND Severe cervical spine injury in rugby union (rugby) exerts a major impact on the individual who sustains the injury and on the broader society. Since the late 1970s, authors of rugby case report studies have postulated that the underlying mechanism of cervical spine injury is hyperflexion of the neck. However, this is in conflict with findings from more recent experimental studies. T...

RECOMMENDATIONS Standards: A three view cervical spine series (AP, lateral, and odontoid views) is recommended for radiographic evaluation of the cervical spine in patients who are symptomatic following traumatic injury. This should be supplemented with computed tomography to further define areas that are suspicious or not well visualized on the plain cervical x-rays. Guidelines: There is insuf...

In 2000 a cannulated screw stabilization system for posterior cervical instrumentation was introduced in our department for use in complex cervical fixation procedures. A special feature of the system is the use of thin Kirschner wires for drilling the screw paths and then placing the self-drilling, cannulated screws securely over the wires. Percutaneous application of C1-C2 transarticular scre...
