OBJECTIVE To determine the effectiveness of the Rapid Form Cervical Vacuum Immobilizer in controlling the cervical spine movements of a football player wearing shoulder pads and a helmet. DESIGN AND SETTING We used a 1-group, repeated-measures experimental design to radiographically assess cervical spine range of motion with and without the Rapid Form Cervical Vacuum Immobilizer. Two experime...

CONTEXT Knee bending during tests of lumbar forward bending (FB) may introduce confounding variability. Precluding bending at the knees has, therefore, long been standard protocol to produce valid and reproducible results. However, there is limited research on cervical spine bending as a confounding variable in whole trunk and lumbar FB. OBJECTIVE To examine the role of cervical spine bending...

To determine if helmet removal causes a significant increase in lordosis of the cervical spine in ice hockey players, we radiographically assessed the position of the cervical spine in subjects immobilized to a standard spine backboard wearing shoulder pads both with and without a helmet. Ten adult male volunteers (ages, 18 to 28 years) with no previous history of cervical spine injuries were f...

INTRODUCTION Laryngoscopy and endotracheal intubation in the presence of cervical spine instability may put patients at risk of cervical cord injury. Nevertheless, the biomechanics of intubation (cervical spine motion as a function of applied force) have not been characterized. This study characterized and compared the relationship between laryngoscope force and cervical spine motion using two ...

OBJECTIVE The purpose of this study was to prospectively assess the sensitivity and efficacy of clinical examination for screening of cervical spine (c-spine) injury in awake and alert blunt trauma patients with concomitant "distracting injuries." METHODS During the 24-month period from December 2009 to December 2011, all blunt trauma patients older than 13 years were prospectively evaluated ...

Kinematic magnetic resonance imaging can be implemented as a non-invasive adjunct examination for injuries in the cervical spine in the clinical assessment of ligamentous, disk, and soft tissue injuries, as a basis for determining medical versus surgical management, and also establishing the degree of functional clinical impairment. This article discusses the clinical indications and applicatio...

cervical injury, blunt and penetrating trauma, hardly lead to morbidity and mortality in children population but it is clinically important. although blunt trauma is less prevalence in children than penetrating trauma, it is life threatening due to laryngotracheal rupture. bicycle accidents are common reason of blunt trauma. blunt laryngotracheal injury is rare in children because mandibular bo...

The cervical spine is one of the most complex structures of the human skeleton. The knowledge of the cervical spine kinematics is a very important tool for many clinical applications such as diagnosis, treatment and surgical interventions and for the development of new spinal implants. The finite element method (FEM) is a well-known and widely used numerical method to simulate structural behavi...

INTRODUCTION Emergency management of upper cervical spine injuries often requires cervical spine immobilisation and some critical patients also require airway management. The movement of cervical spine created by tracheal intubation and cervical spine immobilisation can potentially exacerbate cervical spinal cord injury. However, the evidence that previous studies have provided remains unclear,...

OBJECTIVE To describe cervical spine abnormalities in a group of adult patients with refractory juvenile chronic arthritis (JCA) complicated by secondary amyloidosis (SA). METHODS The series consists of 49 patients who fulfilled the diagnostic criteria of the European League Against Rheumatism for JCA, here complicated by secondary amyloidosis (SA). We evaluated their clinical records and mos...
