The finite element model has been used as an effective tool in human spine biomechanics. Biomechanical finite element models have provided basic insights into the workings of the cervical spine system. Advancements in numerical methods during the last decade have enabled researchers to propose more accurate models of the cervical spine. The new finite element model of the cervical spine conside...

The purpose of this study was to evaluate cervical spine function, based on our own functional method of roentgenometric analysis in patients who suffered from cervical spine sprain injury. Study involved 72 patients who suffered from cervical spine whiplash injury. Conventional plain radiographs in all patients included three lateral views: maximum flexion, neutral (resting) and maximum extens...

BACKGROUND Although cervical spine trauma is more common following high velocity mechanisms of injury resulting in multiple injuries, falls and low velocity mechanisms may also result in serious cervical spine injury. OBJECTIVE This article describes the assessment and management of potential cervical spine injury in the primary care setting. DISCUSSION Patients presenting following trauma ...

OBJECTIVE To develop and validate an extensive radiographic scoring system for ankylosing spondylitis (AS). METHODS The Stoke Ankylosing Spondylitis Spinal Score (SASSS) was modified by adding a score for the cervical spine and defining squaring. This modified SASSS (mSASSS) is the sum of the lumbar and cervical spine score (range 0-72). 370 lateral views of the lumbar and cervical spine were...

The use of posterior cervical spine fixation has become increasingly popular in recent years. Dissatisfaction with lateral mass fixation, especially at the cervicothoracic junction, has led spine surgeons to use cervical pedicle screw fixation for reconstruction in numerous cervical spine disorders. The biomechanical advantage of a three-column fixation device implanted to secure an unstable ce...

OBJECTIVE: To determine frequency of improvement in anatomical alignment of cervical spine with skeletal traction in patients with cervical spine injury. METHODOLOGY: This retrospective observational study was conducted at neurosurgery department, Lady Reading Hospital, Peshawar. The medical record of all cases from December 2010 to November 2011, in which cervical traction was applied for cerv...

Cervical spinal instability due to ligamentous injury, degenerated disc and facetectomy is a subject of great controversy. There is no analytical investigation reported on the biomechanical response of cervical spine in these respects. Parametric study on the roles of ligaments, facets, and disc nucleus of human lower cervical spine (C4-C6) was conducted for the very first time using noninvasiv...

STUDY OBJECTIVE Previous studies of cervical spine injury involve individual institutions or special populations. There is currently little reliable information regarding natural cervical spine injury patterns after blunt trauma. This substudy of the National Emergency X-Radiography Utilization Study project was designed to accurately assess the prevalence, spectrum, and distribution of cervica...

STUDY HYPOTHESIS Cervical-spine radiography does not need to be performed on selected blunt trauma patients who are awake, alert, nonintoxicated, do not complain of midline neck pain, and have no tenderness over the bony cervical spine. STUDY POPULATION One thousand consecutive patients seen in the UCLA Emergency Medicine Center with a chief complaint of blunt trauma, for whom cervical-spine ...

THE JOURNAL OF BONE AND JOINT SURGERY tions, including 24-hour ambulant monitoring, revealed only atrial fibrillation. Radiographs of the cervical spine showed spondylolisthesis at the C5 to C6 level. Anterior cervical interbody fusion was performed at this level; the bony changes seen at operation were similar to those described in case 1. He had no more drop attacks during the last year of hi...
