Abstract
Spinal Cord Injury (SCI) in the pediatric population is relatively rare but carries significant psychological and physiological consequences. An interdisciplinary group of experts composed of medical and surgical specialists treating patients with SCI formulated the following questions: 1) What is the epidemiology of pediatric spinal cord injury and fractures?; 2) Are there unique features of pediatric SCI which distinguish the pediatric SCI population from adult SCI?; 3) Is there evidence to support the use of neuroprotective approaches, including hypothermia and steroids, in the treatment of pediatric SCI? A systematic review of the literature using multiple databases was undertaken to evaluate these three specific questions. A search strategy composed of specific search terms (Spinal Cord Injury, Paraplegia, Quadriplegia, tetraplegia, lapbelt injuries, seatbelt injuries, cervical spine injuries and Pediatrics) returned over 220 abstracts that were evaluated and by two observers. Relevant abstracts were then evaluated and papers were graded using the Downs and Black method. A table of evidence was then presented to a panel of experts using a modified Delphi approach and the following recommendation was then formulated using a consensus approach: Pediatric patients with traumatic SCI have different mechanisms of injury and have a better neurological recovery potential when compared to adults. Patients with SCI before their adolescent growth spurt have a high likelihood of developing scoliosis. Because of these differences, traumatic SCI should be highly suspected in the presence of abnormal neck or neurological exam, a high-risk mechanism of injury or a distracting injury even in the absence of radiological anomaly.

Abstract
The authors report a case of dens fracture and complete quadriplegia in a 14-month-old child. Three months after reduction with a halo vest, there was no evidence of callus formation, so transoral transpharyngeal bone grafting and Minerva immobilization was performed, resulting in prompt healing without complications after 2 months, and a full neurological recovery and normal cervical spine motion at the 4-year follow-up.

Abstract
PURPOSE Instable upper cervical spine injuries (CSI) in very young children are rare and consecutively only few data on the treatment and operative approaches exist in the literature. Hence, we suggest an operative strategy in the case of a 15-month-old infant treated for an instable CSI at the level of C2/3 at our department. Detailed steps of the operation with special consideration to the challenging anatomy of the immature spine are presented. METHODS A toddler suffered a CSI without neurological deficits after a stair fall. Computer tomography (CT) and magnetic resonance imaging (MRI) of the cervical spine revealed an instable luxation fracture of C2/3. As repositioning in the halo vest immobilization failed, surgical fusion was indicated. RESULTS Via a posterior midline approach, the lamina of C2 and C3 was conflated in a modified sublaminar wiring technique using non-resorbable sutures, sparing the ossification zones of the vertebral arches. Postoperative immobilization in a halo vest facilitated bony fusion of the laminae at C2/3 without lordotic displacement of the cervical spine. CONCLUSIONS We consider the instable CSI of the immature cervical in the very young a challenging situation for every treating physician. The particular features of the growing spine require special attention to avoid damage to the growth centers of the vertebrae. To our knowledge, this is the first technical report giving detailed information of an operative approach to the severely injured immature cervical spine and postoperative management.

Abstract
The mechanism location and type of injury varies according to patient age and severity of trauma. The imaging work-up with radiographs, CT and MRI must be adapted to each individual case. In the setting of minor trauma, standard radiographs are obtained when clinically indicated. In all other cases of high energy trauma, spinal trauma with neurological deficit or incomplete or difficult standard radiographic evaluation, CT will be indicated for osseous injuries while MRI will provide optimal evaluation of soft tissues. Dislocations require immediate treatment. The imaging work-up should by no means delay management. Significant sprains are rare. Several diagnostic pitfalls occur at both extremities of life.

Abstract
BACKGROUND The diagnosis and management of cervical spine injury is more complex in children than in adults. OBJECTIVES Part I of this series stressed the importance of tailoring the evaluation of cervical spine injuries based on age, mechanism of injury, and physical examination findings. Part II will discuss the role of magnetic resonance imaging (MRI) as well as the management of pediatric cervical spine injuries in the emergency department. DISCUSSION Children have several common variations in their anatomy, such as pseudosubluxation of C2-C3, widening of the atlantodens interval, and ossification centers, that can appear concerning on imaging but are normal. Physicians should be alert for signs or symptoms of atlantorotary subluxation and spinal cord injury without radiologic abnormality when treating children with spinal cord injury, as these conditions have significant morbidity. MRI can identify injuries to the spinal cord that are not apparent with other modalities, and should be used when a child presents with a neurologic deficit but normal X-ray study or CT scan. CONCLUSION With knowledge of these variations in pediatric anatomy, emergency physicians can appropriately identify injuries to the cervical spine and determine when further imaging is needed.

Abstract
OBJECT The incidence, type, and severity of pediatric cervical spine injuries (CSIs) are related to age and mechanism of injury. In this study, the authors assessed the prevalence of CSIs in infants with head trauma treated in their institution. METHODS The authors reviewed the medical records of children younger than 1 year of age who presented to The Children's Hospital with head injuries between January 1993 and December 2007. They excluded infants with head injuries resulting from motor vehicle accidents and known falls from heights greater than 10 ft. For each patient, collected data included age, cause of injury, diagnosis, discharge disposition, and outcome. Relevant imaging data were reviewed, and when appropriate, autopsy reports were also reviewed. RESULTS Nine hundred five infants with head trauma and without a major mechanism/cause were identified. Their mean age was 4.3 months. Of the 905 patients, only 2 cases of CSI were detected, giving a prevalence of 0.2%. The mechanism of injury in these 2 patients was nonaccidental trauma (NAT). CONCLUSIONS The study revealed a very low prevalence of CSIs in infants with head trauma (0.2%). Routine cervical spine imaging in these infants, therefore, appears to have low diagnostic yield. The mechanism of head injury was NAT in the 2 patients who sustained an associated CSI. This supports the need for more stringent cervical spine imaging criteria for the infant with suspected NAT.

Abstract
BACKGROUND Spinal injury in pediatric trauma is associated with significant morbidity and mortality, but no current consensus exists on the safest and most effective method of clearance in the high-risk pediatric trauma patient. METHODS A retrospective analysis was performed on the records of 115 pediatric patients who had suffered major trauma and required admission to the pediatric intensive care unit of a United Kingdom level I trauma centre during a 7-year period from January 2000 to December 2006. The spinal imaging performed, and methods of clearance for each spinal region were obtained from analysis of written and electronic medical documentation. RESULTS In the cohort of 115 patients, there was a male predominance (63%) with motor vehicle accidents as the major mechanism of injury (63.5%). Ten patients (8.7%) were identified with spinal injuries, all of whom had sustained closed head injuries. Two of these patients had spinal cord injuries; one subsequently died. Spinal injury resulted in longer intubation times and intensive care stays, but no difference in new injury severity score or outcome. Clearance methods ranged from clinical examination to imaging with radiographs, computed tomography (CT), and dynamic screening. Magnetic resonance imaging was used as a secondary modality in two cases only, and in neither case was it used for clearance. CT demonstrated 100% specificity and sensitivity with positive and negative predictive values of 1 for all spinal regions. There were no cases of Spinal Cord Injury WithOut Radiologic Abnormality and no evidence of missed injuries. CONCLUSIONS There is a need for an evidence-based protocol for the clearance of the spine in the obtunded and high-risk pediatric trauma patient. High-resolution CT with sagittal and coronal reconstructions should be the basis for cervical spinal clearance, in combination with the interpretation of films by an expert radiologist. All spinal regions should be imaged, and clearance should be formally documented. The role of magnetic resonance imaging in routine clearance remains controversial. Multicenter prospective studies are needed to develop consensus for an evidenced-based protocol for clearance in this high-risk group.

Abstract
It is estimated that 3.2 million children ages 6 to 14 years participated in organized youth football in the United States in 2007. Approximately 240,000 children play football in the nation's largest youth football organization, with tackle divisions starting at age 5 years. The number of children playing unsupervised football is much higher, and the overall number of children participating in American football is increasing. Sports are the leading cause of injury-related emergency room visits for teenagers, and football is a leading precipitating athletic activity for these visits. Football is also the most hazardous organized sports in the United States. Though most pediatric football-related injuries are minor, such as abrasions, sprains, and strains of the extremities, football accounts for more major and catastrophic injuries than any other sport. Given football's popularity with children in the United States, combined with the high rate of injury associated with participation in this activity, radiologists should be familiar with the imaging features and injury patterns seen in this patient population.

Abstract
Unstable pediatric cervical spine injuries present significant challenges in terms of fixation. Given the smaller cervical vertebral bodies in the preschool-aged population, commercially available pediatric cervical fixation instrumentation may be unsuitable because of the inappropriately large size of the screws and plates. The authors describe a 2-year-old girl who sustained an unstable C6-7 distraction injury during a motor vehicle accident. Because of the small size of her vertebral bodies, standard cervical spine instrumentation was not feasible, and posterior wiring alone was believed to be insufficient because of the complete distraction of all 3 spinal columns. The patient was taken to the operating room where craniofacial plates with an inherent locking mechanism were used to circumferentially stabilize the cervical spine. Follow-up examination 6 months postoperatively demonstrated stable cervical spine alignment and fusion with no evidence of the failure of either the anterior or posterior hardware. The use of craniofacial miniplates with an intrinsic locking mechanism represents a superior alternative for both anterior and posterior cervical fixations when spinal instrumentation is needed in the pediatric age group.

Abstract
We present a rare case of a combined dislocated odontoid dens fracture type II (Anderson/D'Alonzo) and rotational atlantoaxial luxation in a 15-year-old girl who was involved in a riding accident.She fell off her horse after it had stopped suddenly, losing consciousness for a few minutes. At presentation in the hospital, she had no complaints other than limited, painful neck movement. Radiologically, a posterior dislocation of an odontoid type II fracture (Anderson/D'Alonzo) was found. Computed tomography reconstruction demonstrated a rotational, hooklike fixed luxation of the left atlantoaxial facet joint. Manual repositioning after application of a cervical collar failed. Therefore, operative treatment was indicated for this highly unstable fracture. Posterior transarticular atlantoaxial screw fixation according to Magerl was performed; an iliac corticocancellous bone graft was harvested and shaped to conform to the posterior processes of C1 and C2. Additionally a hook-claw atlas fixation of C1 was done.To our knowledge, this is the first case of adolescent atlantoaxial cervical spine trauma in combination with an odontoid fracture and fixed rotational luxation reported in literature.

Abstract
AIM To improve insight into fatal child cervical spine injuries (CSI) caused by motor vehicle collisions. METHOD Two large national mortality datasets were linked at the level of the individual decedent to analyse and compare anatomical injuries and vehicle crash characteristics for fatally injured child occupants. RESULTS Cervical spine injury was identified among 176 of 6065 child (age 0-15 years) motor vehicle occupant fatalities. Presence compared with absence of CSI had significant association with female gender, traumatic brain injury and seat restraint, but not with age, vehicle model, year or type, exposure to airbag, severe vehicle intrusion, collision speed or direction, drivability of the vehicle or seating position. CONCLUSIONS Cervical spine injury, which was uncommon in the studied subset of child decedents, was associated with female gender, the use of passenger restraints and the presence of traumatic brain injury.

Abstract
PURPOSE The Canadian C-spine (cervical spine) Rule (CCR) and the National Emergency X-Radiography Utilization Low-Risk Criteria (NLC) are criteria designed to guide C-spine radiography in trauma patients. It is unclear how these 2 rules compare with young children. METHODS This study retrospectively examined case-matched trauma patients 10 years or younger. Two cohorts were identified-cohort A where C-spine imaging was performed and cohort B where no imaging was conducted. The CCR and NLC criteria were then applied retrospectively to each cohort. RESULTS Cohort A contained 125 cases and cohort B with 250 cases. Seven patients (3%) had significant C-spine injuries. In cohort A, NLC criteria could be applied in 108 (86.4%) of 125 and CCR in 109 (87.2%) of 125. National Emergency X-Radiography Utilization Low-Risk Criteria suggested that 70 (58.3%) cases required C-spine imaging compared to 93 (76.2%) by CCR. National Emergency X-Radiography Utilization Low-Risk Criteria missed 3 C-spine injuries, and CCR missed one. In cohort B, NLC criteria could be applied in 132 (88%) of 150 and CCR in 131 (87.3%) of 150. The NLC criteria identified 8 cases and CCR identified 13 cases that would need C-spine radiographs. Fisher's 2-sided Exact test demonstrated that CCR and NLC predictions were significantly different (P = .002) in both cohorts. The sensitivity of CCR was 86% and specificity was 94%, and the NLC had a sensitivity of 43% and a specificity of 96%. CONCLUSIONS Although CCR and NLC criteria may reduce the need for C-spine imaging in children 10 years and younger; they are not sensitive or specific enough to be used as currently designed.

Abstract
The relative rarity of pediatric cervical spine injuries can impede rapid response and efficient care of this patient population. An understanding of the unique anatomical, radiographic, and biomechanical characteristics of the pediatric cervical spine is essential to the appropriate care of these challenging patients. Patterns of injury, diagnosis, and issues related to operative and nonoperative management are discussed with a focus on the developing spine. Our aim is to improve the understanding of traumatic cervical spine injuries in children for all practitioners involved with their care.

Abstract
OBJECT In this study, the authors estimate the prevalence of injuries to the soft tissue of the neck, cervical vertebrae, and cervical spinal cord among victims of abusive head trauma to better understand these injuries and their relationship to other pathophysiological findings commonly found in children with fatal abusive head trauma. METHODS The population included all homicide victims 2 years of age and younger from the city of Philadelphia, Pennyslvania, who underwent a comprehensive postmortem examination at the Office of the Medical Examiner between 1995 and 2003. A retrospective review of all available postmortem records was performed, and data regarding numerous pathological findings, as well as the patient's clinical history and demographic information, were abstracted. Data were described using means and standard deviations for continuous variables, and frequency and ranges for categorical variables. Chi-square analyses were used to test for the association of neck injuries with different types of brain injury. RESULTS The sample included 52 children, 41 (79%) of whom died of abusive head trauma. Of these, 29 (71%) had primary cervical cord injuries: in 21 there were parenchymal injuries, in 24 meningeal hemorrhages, and in 16, nerve root avulsion/dorsal root ganglion hemorrhage were evident. Six children with abusive head trauma had no evidence of an impact to the head, and all 6 had primary cervical spinal cord injury (SCI). No child had a spinal fracture. Six of 29 children (21%) with primary cervical SCIs had soft-tissue (ligamentous or muscular) injuries to the neck, and 14 (48%) had brainstem injuries. There was a significant association of primary cervical SCI with cerebral edema (p = 0.036) but not with hypoxia-ischemia, infarction, or herniation. CONCLUSIONS Cervical SCI is a frequent but not universal finding in young children with fatal abusive head trauma. In the present study, parenchymal and/or root injury usually occurred without evidence of muscular or ligamentous damage, or of bone dislocation or fracture. Moreover, associated brainstem injuries were not always seen. Although there was a significant association of primary cervical cord injury with cerebral edema, there was no direct relationship to brainstem herniation, hypoxia-ischemia, or infarction. This suggests that cervical spinal trauma is only 1 factor in the pathogenesis of these lesions.

Abstract
PURPOSE Computed tomographic (CT) scanning has mostly replaced x-rays as an imaging modality, but concerns exist because of excess radiation, missed injuries, and whether it is the definitive procedure for intubated patients. The purpose of this study was to characterize missed cervical spine injuries (CSIs). METHODS All pediatric (<18) trauma patients from 2004 to 2006 were analyzed. Age, sex, Injury Severity Score (ISS), mechanism, time, and missed injuries were reviewed. Flexion/extension views were used in patients with prolonged intubation. Descriptive statistics, chi(2), Student's t test, and bivariate correlation were used. RESULTS There were 1307 pediatric trauma patients admitted with 318 imaged for potential CSI. Computed tomography was the sole imaging study in 200, x-rays in 64, and both in 54. Time to C-spine clearance was similar for all modalities (P > .05). For CT, 34 (10.7%) were initially positive for CSI with 7 false-positives (FPs) and no false-negative (FN). There were 18 patients with CSI identified by x-ray, with 5 FPs and 5 FNs (missed injuries). The 5 FNs missed by x-ray were all positive by CT scan and required no intervention. None of the flexion/extension views revealed an additional injury. Sex, intubated patients, ISS, age, type, and injury location were not predictive of a missed injury (P > .05).The sensitivity of CT scan was 1.0, specificity was 0.976, and the positive predictive value was 79.4%. The sensitivity of plain x-ray was 61.5%, the specificity was 1.6%, and the positive predictive value was 61.5%. CONCLUSIONS Our data suggest that CT scans should be the primary modality to image a CSI. Flexion/extension views did not add to the decision making for C-spine clearance after CT evaluation.

Abstract
A 21-month-old boy with steroid-dependent asthma presented to the emergency room with Glascow Coma Score (GCS) 3 and retinal hemorrhages. He was found to have subdural and subarachnoid hemorrhage on computed tomography plus findings of hypoxic-ischemic encephalopathy (HIE). The caretaker history was thought to be inconsistent with the clinical and imaging features, and the patient was diagnosed with nonaccidental injury (NAI) and "shaken baby syndrome." The autopsy revealed a cranial impact site and fatal injury to the cervicomedullary junction. Biomechanical analysis provided further objective support that, although NAI could not be ruled out, the injuries could result from an accidental fall as consistently described by the caretaker.

Abstract
OBJECTIVE Current guidelines recommend cervical spine immobilization during orotracheal intubation when traumatic injury is suspected in infants. We evaluated the effect of cervical spine immobilization techniques on orotracheal intubation performance with a high-fidelity infant simulator. METHODS A randomized control study with repeated measurement. Nonanesthesia pediatric practitioners certified for intubation performed 6 intubations with 3 different cervical spine immobilization techniques (no physical protection, manual in-line immobilization, and cervical collar: C-collar). Time to accomplish key actions, cervical extension angle, and observed intubation associated events such as mainstem intubation, esophageal intubation with or without immediate recognition were recorded. RESULTS Twenty-six practitioners performed 156 successful orotracheal intubation. Time to intubation from end of mask assist ventilation was 29.0 +/- 12.2 seconds in no physical protection, 33.0 +/- 17.4 seconds in C-collar, and 33.0 +/- 17.1 seconds in manual in-line immobilization (P = 0.39). Maximal cervical extension angle in no physical protection (2.39 +/- 2.56 degrees ) and C-collar (2.65 +/- 1.79 degrees ) were significantly greater compared with 0.85 +/- 1.05 degrees in manual in-line immobilization (P < 0.0001). The number of intubation attempts and intubation associated events were not different among 3 techniques. Laryngeal visualization measured by Cormack-LehaneScale was more difficult in C-collar compared with other 2 techniques (P< 0.001). CONCLUSIONS In this high-fidelity infant simulator model, cervical spine immobilization technique affected cervical extension angle and laryngeal visualization. Tracheal intubation associated events occurred in 33% of intubation attempts but were not different by technique. Time to achieve tracheal intubation, number of intubation attempts needed to succeed, and intubation-associated events were not affected by immobilization techniques. These results support Advanced Trauma Life Support recommendations to perform manual in-line immobilization in infants.

Abstract
BACKGROUND Blunt cervical spine injury (CSI) is rare in the pediatric population. The objective of this study was to better characterize the incidence and type of CSI in young children (age <3 years) using a large, trauma center-based data set. METHODS The National Trauma Data Bank (NTDB) was reviewed for the period January 2001 to December 2005 for patients younger than 3 years of age with a blunt CSI (International Classification of Diseases, Ninth Revision, 805x, 806x, 952x). Demographic, injury, and outcome information were reviewed. Data management was performed using SAS (SAS, Cary, NC) and Stata (Stata Corp, College Station, TX). Patients with CSI were compared to patients without CSI of similar age. Means were compared with the Wilcoxon rank sum test, medians were compared with a nonparametric test, and count data were compared with the chi(2) test, with significance set at <.05. RESULTS For the period of review, 95,654 young children (age <3 years) with blunt trauma were identified in the NTDB. The overall population had a median Injury Severity Score (ISS) of 4, and most patients (77.01%) had a Glasgow Coma Score (GCS) of 15. There were 1523 (1.59%) patients with a CSI (spinal cord and/or column), including 366 patients (0.38%) with a spinal cord injury (with or without column injury) and 182 (0.19%) with an isolated spinal cord injury (SCIWORA). The CSI and non-CSI populations did not differ regarding median GCS (15 for both groups), but the CSI population had a significantly higher median ISS (14 vs 4, respectively; P < .001). Compared to patients without CSI, the CSI population was more likely to die in the emergency department (2.04% vs 1.25%; P = .007) or be admitted to the intensive care unit (45.3% vs 16.9%; P < .001). Nearly half of all cervical spine fractures (48%) and more than half of cervical spinal cord injuries (53%) were in the lower cervical spine (C5-7). MVCs were the most common injury mechanism (66%) followed by falls (15%). A CSI was observed in 3.2% of all motor vehicle crashes (MVCs). CONCLUSIONS In this trauma center population, these findings confirm the infrequency of blunt CSI in the youngest (age <3 years) trauma patients. The frequency of injuries to the lower cervical spine is higher than previously appreciated. MVCs are the most likely injury mechanism for this potentially devastating injury.

Abstract
BACKGROUND Substantial literature exists regarding recommendations for the on-field treatment and subsequent transportation of adult collision-sport athletes with a suspected injury to the cervical spine. PURPOSE To develop an evidence-based recommendation for transportation of suspected spine-injured youth football players. STUDY DESIGN Descriptive laboratory study. METHODS Three lateral radiographs were obtained in supine to include the occiput to the cervical thoracic junction from 31 youth football players (8-14 years). Each child was imaged while wearing helmet and shoulder pads, without equipment, and with shoulder pads only. Two independent observers measured cervical spine angulation as Cobb angle from C1 to C7 and subaxial angulation from C2 to C7. We calculated intraclass correlation coefficients for intraobserver reliability analysis and compared Cobb and C2 to C7 angles between equipment conditions with t tests. RESULTS Interobserver analysis showed excellent reliability among measurements. Cobb and subaxial angle measurements indicated significantly greater cervical lordosis while children wore shoulder pads only, compared with the other 2 conditions (no equipment and helmet and shoulder pads) (P <or= .001). There was no statistically significant difference in either Cobb or C2-C7 angles between fully equipped (helmet + shoulder pads) and no-equipment conditions (P >.05). CONCLUSIONS Equipment removal for the youth football athlete with suspected cervical spine injury should abide by the "all or none" policy that has been widely accepted for adult athletes. Helmet and shoulder pads should be left in place during emergency transport of the suspected spine-injured youth athlete. CLINICAL RELEVANCE Despite differences in head to torso size ratios between youth and adult players, helmet removal alone is not recommended for either during emergency transportation.

Abstract
OBJECTIVE In evaluating the pediatric cervical spine for injury, the use of adult protocols without sufficient sensitivity to pediatric injury patterns may lead to excessive radiation doses. Data on injury location and means of detection can inform pediatric-specific guideline development. METHODS We retrospectively identified pediatric patients with codes from the International Classification of Diseases, 9th Revision, for cervical spine injury treated between 1980 and 2000. Collected data included physical findings, radiographic means of detection, and location of injury. Sensitivity of plain x-rays and diagnostic yield from additional radiographic studies were calculated. RESULTS Of 239 patients, 190 had true injuries and adequate medical records; of these, 187 had adequate radiology records. Patients without radiographic abnormality were excluded. In 34 children younger than 8 years, National Emergency X-Radiography Utilization Study criteria missed two injuries (sensitivity, 94%), with 76% of injuries occurring from occiput-C2. In 158 children older than 8 years, National Emergency X-Radiography Utilization Study criteria identified all injured patients (sensitivity, 100%), with 25% of injuries occurring from occiput-C2. For children younger than 8 years, plain-film sensitivity was 75% and combination plain-film/occiput-C3 computed tomographic scan had a sensitivity of 94%, whereas combination plain-film and flexion-extension views had 81% sensitivity. In patients older than 8 years, the sensitivities were 93%, 97%, and 94%, respectively. CONCLUSION Younger children tend to have more rostral (occiput-C2) injuries compared with older children. The National Emergency X-Radiography Utilization Study protocol may have lower sensitivity in young children than in adults. Limited computed tomography from occiput-C3 may increase diagnostic yield appreciably in young children compared with flexion-extension views. Further prospective studies, especially of young children, are needed to develop reliable pediatric protocols.

Abstract
Cervical spine and spinal cord injuries are rare in pediatric trauma victims. The majority result from blunt trauma. Spinal cord injury without radiographic abnormality has been reported to be more common among young children than adults. The Brown-Séquard syndrome is rarely seen as the result of blunt trauma. We present the case of young boy who suffered spinal cord injury without radiographic abnormality resulting in the Brown-Séquard syndrome and review the controversy surrounding the use of high-dose corticosteroids in the treatment of pediatric spinal cord injury. Current data do not support the use of corticosteroids as 'standard of care' for this population.

Abstract
Five infants and toddlers who sustained cervical spinal cord injury as the result of child abuse are described. Three cases are previously unreported. Diagnosis was complicated by coexistent brain injuries and their treatments, subtle and/or evolving paralysis, and central cord syndrome, in which arm function is diminished but leg function is preserved. Definitive spinal imaging by magnetic resonance imaging (MRI), computed tomography, and plain radiographs was delayed because of life support efforts. When completed, the MRI was most sensitive to cord injury. Evidence of associated bony spinal injury was often absent or unapparent until healing occurred; 4 children had spinal cord injury without (or with minimal) radiological abnormality. The 3 children presenting to our hospital with cord injury represent 1% of the estimated cases of inflicted head injury seen during a 23-year period.

Abstract
Injuries to the pediatric cervical spine occur infrequently. Numerous unique anatomic and biomechanical features of the pediatric spine render it much more flexible than the adult spine. These features give rise to significant differences in the presentation, diagnosis, treatment, and prognosis of pediatric cervical trauma compared with adults. Younger children more often suffer injury to the upper cervical spine with greater neurologic injury and fewer fractures. Once the child reaches the age of 10 years, he or she develops a more adult-type spine, and injuries are thus more similar to those seen in the adult population. The unique anatomic and biomechanical differences in the pediatric spine are discussed, along with the various common and unique injuries.

Abstract
OBJECTIVE This study focuses on methods to reduce injuries, specifically in the head and neck region, sustained by children seated in forward-facing child restraint system during a frontal vehicle crash. The main objective of this research was to implement load-limiting behavior into the upper tether and lower LATCH anchors of the CRS in order to reduce the neck injury criteria by increasing forward head excursion. METHODS Federal Motor Vehicle Safety Standard 213 outlines that the maximum limit for head excursion of the child dummy should be 720 mm, and the neck injury criteria should be less than 0.33 beyond the first 30 ms of the impact. Working within these limits, a fully deformable finite element model of a child restraint seat incorporating a Hybrid III 3-year-old dummy has been previously developed that has been validated for frontal impacts under CMVSS 208 and FMVSS 213 testing conditions. Observations from this previous work have illustrated that despite the head excursion being significantly less than the proposed limit of 720 mm, values of the neck injury criteria exceeded the protection reference values. Values of the load limits for both upper tether and lower LATCH anchors were calculated based on two approaches, initially based upon neck injury criteria and then an energy-based approach. Three numerical models were developed incorporating a Hybrid III 3-year-old dummy, Q3 child dummy, and a child finite element model. Numerical simulations, utilizing the identical 213 testing conditions, were completed incorporating load-limiting capabilities of the upper tether and lower LATCH anchors. RESULTS Evaluation of injury criteria based on the quantitative analysis of the simulations yielded that the implementation of load-limiting behavior in the upper tether and lower LATCH anchors was effective in reducing the head injury criteria by approximately 60 to 70%. CONCLUSION Implementation of load-limiting behavior in the upper tether and lower LATCH anchors of the child restraint system effectively reduces the head and neck injuries sustained by toddlers in a frontal vehicle crash while controlling forward head excursion within the limits as defined by NHTSA.

Abstract
INTRODUCTION This study examines the management and outcome of cervical spine injuries in children with head injuries, to assess the need for surgical treatment. MATERIAL AND METHODS We performed a retrospective analysis (1995-2005) of 445 children admitted intubated and ventilated to the intensive care unit with head injuries. OUTCOME MEASURES Frankel grade for spinal injuries and Glasgow Outcome Scale (GOS) for head injuries. RESULTS Cervical spine injuries were detected in 11 patients (incidence 2.5%, mean age: 6.3 years, range: 21 months-15 years). The injuries were: C1/2 distraction: 2; C1/2 subluxation: 2; odontoid peg fracture with C1/2 dislocation and cord transection: 1; disruption of posterior longitudinal ligament at C2: 1; odontoid peg fracture with C2/3 distraction: 1; C2/3 subluxation: 1; C3 lamina fracture: 1; C3/4 facet fracture: 1; C6/7 fracture dislocation with cord transection: 1. One patient was managed operatively, ten patients nonoperatively, two with halo vests and eight with hard collars. There were three deaths (mortality 27%) associated with severe head injuries. At 6 months follow-up, two patients remained quadriplegic (Frankel Grade A), one of them ventilator dependent, one had residual motor function but of no practical use (Frankel Grade C), five had good spinal outcome (Frankel Grade E). Seven patients had good head injury outcomes (GOS 5), one remained disabled (GOS 3). CONCLUSION Most children with cervical injury can be managed nonoperatively with good outcomes. Surgical management may be necessary in severe unstable injuries.

Abstract
A review of the various causes of neurologic impairment to the lower urinary tract in children was the aim of this presentation. The emphasis was on diagnosis, pathophysiology, and treatment that strive to maintain as normal a function as possible in order to achieve eventual urinary continence and health of the upper urinary tract. The latest principles based on the most up to date evidence are promulgated but with an eye towards historical prospective. The reader should gain an adequate understanding of various disorders that comprise this condition and feel comfortable with proposing options for management when faced with the responsibility of caring for an affected child.

Abstract
Pedestrian traffic injuries are a growing public health threat worldwide. The global economic burden of motor vehicle collisions and pedestrian injuries approximates $500 billion. In the United States, the number of pedestrian fatalities increased from 4675 in 2004 to 4881 in 2005. In addition nearly 60,000 injuries occurred during the same year. Injury patterns vary depending on the age, sex, and socioeconomic status of the individual. Children comprise one of the most vulnerable populations in pedestrian traffic injuries. Pedestrian injury remains the second leading cause of unintentional injury-related death among children aged 5 to 14 years. The burden of injury, upon the individual, families, and society, is frequently overwhelming. From recent data, pedestrian injuries and deaths are increasing in the United States and the World, and they require particular attention by emergency care providers and policy makers.

Abstract
STUDY DESIGN Retrospective case review. OBJECTIVE This study aims to characterize a broad spectrum of spinal injuries, from minor soft tissue injuries to spinal cord injuries. We hypothesized that the pattern of pediatric spinal injury would depend on age and cause. SUMMARY OF BACKGROUND DATA While pediatric spinal trauma is generally considered to be rare, the impact of serious spinal trauma is considerable, both in medical and socioeconomic terms. Comparison of serious and minor injuries has rarely been carried out for pediatric spinal injury cases. METHODS All children up to age 16 who sustained spinal trauma, as defined by ICD10 codes, at 2 pediatric trauma hospitals in Sydney, Australia were identified (N = 340). Data on injury mechanism (defined as the causative event), type, and spinal level were collected and analyzed using logistic regression. RESULTS Traffic-related incidents accounted for approximately one third of all spinal trauma and half of serious injuries. The cervical spine was the most frequently injured region, with thoracic and lumbar spine injuries becoming more common with age. The upper cervical spine was more commonly seriously injured in young children, and the lower cervical spine was involved more often in older children. The frequency of minor soft tissue neck injuries increased substantially above the age of 8. Serious spinal injury is more likely to occur in conjunction with multiple trauma. Road traffic incidents were more likely to result in serious spinal injury than falls or sporting incidents. CONCLUSION This study has shown that the pattern of spinal injury in children is related to age and also the mechanism of injury. While traffic-related incidents are a leading cause of injury across all age groups, emphasis on fall prevention is needed for younger children. Older children, particularly boys, are sustaining spinal trauma in sporting and recreational activities.

Abstract
This study relates to the case report of a neurologically intact 13-year-old boy with unrecognized traumatic bipedicular vertebral fracture. He was diagnosed complete vertebral body luxation 1 day later by dynamic fluoroscopy, then successfully treated with surgery that resulted in total recovery. The delayed diagnosis highlights the importance of detailed initial clinical and radiology examinations, even when overt symptoms as diagnostic indicators of severe neurological sequelae expected in similar traumatic vertebral fractures are lacking. A 13-year-old boy, who met with a minor bicycle accident, was presented with two small forehead lacerations but without pain or clinical neurological symptoms for radiological examination, which showed no abnormalities. The following day, however, the patient complained about dysphagia and underwent dynamic fluoroscopy for the assessment of deglutition that revealed a total block of contrast medium. Computer tomography (CT) of the cervicothoracic junction showed a bipedicular thoracic vertebral fracture and a hooked vertebral body luxation causing mechanical dysphagia but, surprisingly, without compression of the spinal cord. The patient fully recovered after carefully carried out protracted distension and orthopaedic surgery with vertebral fusion. One year after surgery, the patient had clinically resumed normal function, and CT showed a sufficient vertebral bony consolidation with anatomical alignment. This case exemplifies the importance of careful initial clinical examination and spinal CT after accidents encompassing an increased risk of spinal fractures, even if neurologically unapparent.

Abstract
STUDY DESIGN A factorial study design was used to examine the biomechanical and neuroprotective integrity of the cervical spine throughout maturation using a postmortem baboon model. OBJECTIVE To investigate changes with spinal development that affect the neuroprotective ability of the cervical spine in compressive loading. SUMMARY OF BACKGROUND DATA Child spinal cord injuries claim and debilitate thousands of children in the United States each year. Many of these injuries are diagnostically and mechanistically difficult to classify, treat, and prevent. Biomechanical studies on maturing spinal tissues have identified decreased stiffness and tolerance characteristics for children compared with adults. Unfortunately, while neurologic deficit typically dictates functional outcome, no previous studies have examined the neuroprotective role of the pediatric cervical spine. METHODS Twenty-two postmortem baboon cervical spines across the developmental age spectrum were tested. Two functional spinal unit segments (Oc-C2, C3-C5, and C6-T1) were instrumented with transducers to measure dynamic changes in the spinal canal. These tissues were compressed to 70% strain dynamically, and the resultant mechanics and spinal canal occlusions were recorded. RESULTS Classic injury patterns were observed in all of the specimens tested. The compressive mechanics exhibited a significant age relationship (P < 0.0001). Furthermore, while the peak-percent spinal canal occlusion was not age dependent, the percent occlusion just before failure did demonstrate a significant decrease with advancing age (P = 0.0001). CONCLUSIONS The neuroprotective ability of the cervical spine preceding failure appears to be age dependent, where the young spine can produce greater spinal canal occlusions without failure than its adult counterpart. The overall percent of the spinal canal occluded during a compression injury was not age dependent; however, these data reveal the neuroprotective ability of the child spine to be more sensitive as an injury predictor than the biomechanical fracture data.

Abstract
Case reports of retroclival hematoma are infrequent, and little is known about the mechanism of formation of the lesion, its management strategy, and the outcome in affected patients. The authors report two cases of posttraumatic retroclival hematoma in children and discuss the available literature. Both patients were treated with cervical immobilization and had good outcomes. Retroclival hematomas are rare. Most reported cases involve pediatric patients in whom the hematomas developed in association with trauma. Spinal trauma in children mainly occurs at the craniovertebral junction due to a high fulcrum of cervical motion and results in ligamentous injuries more often than fractures. The formation of epidural hematomas posterior to the clivus is likely to be due to either clivus fracture or ligament disruption. A high index of suspicion is essential in making the diagnosis. Magnetic resonance imaging is superior to computed tomography in demonstrating retroclival hematomas because of its superiority in delineating the extradural spaces and the integrity of the ligaments. The authors conclude that in most cases retroclival hematomas can be treated conservatively and good outcomes can be expected.

Abstract
Because of the widely acknowledged controversy in nonaccidental injury, the radiologist involved in such cases must be thoroughly familiar with the imaging, clinical, surgical, pathological, biomechanical, and forensic literature from all perspectives and with the principles of evidence-based medicine. Children with suspected nonaccidental injury versus accidental injury must not only receive protective evaluation but also require a timely and complete clinical and imaging workup to evaluate pattern of injury and timing issues and to consider the mimics of abuse. All imaging findings must be correlated with clinical findings (including current and past medical record) and with laboratory and pathological findings (eg, surgical, autopsy). The medical and imaging evidence, particularly when there is only central nervous system injury, cannot reliably diagnose intentional injury. Only the child protection investigation may provide the basis for inflicted injury in the context of supportive medical, imaging, biomechanical, or pathological findings.

Abstract
STUDY DESIGN Prospective observational study. OBJECTIVES To identify the epidemiological features specific to spinal injuries as a result of an earthquake. SETTINGS Rawalpindi, Pakistan in the months after the 8 October 2005 earthquake. METHODS In the month after the earthquake, the one established rehabilitation center was augmented with two makeshift spinal cord centers. Information on mechanism of injury, mode of evacuation, associated injuries was gathered, and a detailed clinical and radiological assessment was performed. Neurological status and functional outcome was determined after 10 weeks. RESULTS Of an estimated 650-750 spinal cord injuries, 187 were admitted to these centers, including 80 men and 107 women with a mean age of 28.3+/-12.4 years. Injuries occurred while standing in 57.8% of patients. Most (83.4%) who reached the spinal cord center were airlifted. A urinary catheter had been placed before admission in 91.5%. Most of the patients were paraplegic 89.3, with 50.8% incomplete injuries. Fracture or fracture dislocation was present in 70, and 75% underwent spinal fixation. Although pressure ulcers (28.9%) and urinary tract infections (39%) were common, deep venous thromboses (4.8%) and depression (5.8%) were seldom detected. At 10 weeks, 75% were continent or performing intermittent catheterization. There were no deaths and two births. CONCLUSION After a disaster, evacuation of persons with a spinal cord injury to a specialized center results in low mortality. Response planning for disasters should include early aggressive medical rehabilitation.

Abstract
The Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) are widely used clinical scoring systems to measure the severity of neurologic injury after traumatic brain injury (TBI), but have recognized limitations in infants and small children. Cerebrospinal fluid (CSF) concentrations of neuron-specific enolase (NSE) and S100B show promise as markers of brain injury. We hypothesized that the initial GCS and 6-month GOS scores would be inversely associated with CSF NSE and/or S100B concentrations after severe pediatric TBI. Using banked CSF obtained during ongoing studies of pediatric TBI, NSE and S100B were determined in CSF collected within 24 h of trauma from 88 infants and children with severe TBI (GCS < or = 8) versus 20 non-injured controls. Victims of inflicted (iTBI) and non-inflicted TBI (nTBI) showed similar (>10-fold) increases in both NSE and S100B versus control. Both markers showed overall significant, inverse correlation with GCS and GOS scores. In subgroup analysis, both markers correlated significantly with GCS and GOS scores only in older (>4 years) victims of nTBI; no correlation was found for patients < or =4 years old or victims of iTBI. While confirming the overall correlations between GCS/GOS score and CSF NSE and S100B seen in prior studies, we conclude that these clinical and CSF biomarkers of brain injury do not correlate in children < or =4 years of age and/or victims of iTBI. Although further, prospective study is warranted, these findings suggest important limitations in our current ability to assess injury severity in this important population.

Abstract
✓Sports-related injuries to the spine, although relatively rare compared with head injuries, contribute to significant morbidity and mortality in children. The reported incidence of traumatic cervical spine injury in pediatric athletes varies, and most studies are limited because of the low prevalence of injury. The anatomical and biomechanical differences between the immature spine of pediatric patients and the mature spine of adults that make pediatric patients more susceptible to injury include a greater mobility of the spine due to ligamentous laxity, shallow angulations of facet joints, immature development of neck musculature, and incomplete ossification of the vertebrae. As a result of these differences, 60 to 80% of all pediatric vertebral injuries occur in the cervical region. Understanding pediatric injury biomechanics in the cervical spine is important to the neurosurgeon, because coaches, parents, and athletes who place themselves in positions known to be associated with spinal cord injury (SCI) run a higher risk of such injury and paralysis. The mechanisms of SCI can be broadly subclassified into five types: axial loading, dislocation, lateral bending, rotation, and hyperflexion/hyperextension, although severe injuries often result from a combination of more than one of these subtypes. The aim of this review was to detail the characteristics and management of pediatric cervical spine injury.

Abstract
INTRODUCTION Pediatric acute spinal cord injury is rare but is often associated with significant disability and prolonged stay in the intensive care unit (ICU). OBJECTIVES The main objective of this study was to determine the epidemiology, initial clinical abnormalities, diagnostic studies, treatment and outcome of acute spinal cord injuries in a tertiary level pediatric hospital. A second objective was to analyze whether early tracheostomy allows earlier discharge of these patients. PATIENTS AND METHODS A retrospective analysis of patients with acute spinal cord injuries admitted to our pediatric ICU since 1992 was performed. RESULTS We included 16 patients in the study, 12 of whom were boys (75 %). The patients were aged from birth to 19 years on admission to the ICU. The length of stay in the ICU was between 12 hours and 6 years. The cause of the lesion was birth trauma in four patients; one died and the remaining three live at home under mechanical ventilation. Traumatic injuries occurred in seven patients, two of whom died; a further two live in a long-term care facility and the remaining three live at home. Vascular spinal malformation occurred in two patients, and the three remaining injuries occurred during the acute postoperative period following spinal surgery. Of the 16 children, 56.2 % were tracheostomized and 83 % of the survivors live at home. CONCLUSIONS Early tracheostomy, the availability of invasive ventilation for home use and parent education permit earlier discharge of these patients and allow more of them to live at home.

Abstract
Injury to the pediatric cervical spine is uncommon; however, a missed or delayed diagnosis can lead to disastrous consequences. Thus, following trauma, clearance of the pediatric cervical spine is important. Problematic issues include child compliance with examination, the complex anatomy of the pediatric cervical spine, lack of agreement on definitive imaging modalities, and the coordination of multiple medical specialties. Expediting clearance of the pediatric cervical spine requires an organized, multidisciplinary approach. In addition to systematic procedures within the emergency department, preventing missed and delayed diagnoses of cervical spine injury can be facilitated by applying a clear methodology for reviewing radiographs in conjunction with the child's clinical examination. This algorithm considers the adequacy of the images, alignment of the bony and soft-tissue elements, assessment of the cervical intervals, and the presence of abnormal angulation. Together with standard treatment, this protocol facilitates effective and expeditious clearance of the cervical spine.

Abstract
Halo application is a standard method for cervical immobilization. However, complications may occur in children because of their thin skull and immature bone. The authors report two cases of odontoid fracture in preschool children treated with a Minerva cast. Two 4-year-old children sustained displaced odontoid fractures in motor vehicle accidents. The fractures were immediately reduced and immobilized using a Minerva cast, followed by the application of a soft collar. By the 1-year follow-up, uneventful bone union had occurred, and the children were able to attend preschool with minimal or no neurologic deficits. The Minerva cast is a classic, inexpensive method of cervical immobilization and is still useful for this kind of fracture. Immediate reduction and immobilization with a Minerva cast is a viable option for displaced odontoid fractures in preschool children.

Abstract
OBJECT In this study the authors evaluated the mechanisms and patterns of injury and the factors affecting management and outcome of pediatric subaxial cervical spine injuries (C3-7). METHODS Fifty-one pediatric patients (38 boys and 13 girls; mean age 12.4 years, range 10 months-16 years) with subaxial cervical spine injuries were reviewed retrospectively. Motor vehicle accidents (MVAs) were the most common cause of injury. Overall, 12% presented with a dislocation, 63% with a fracture, 19% with a fracture-dislocation, and 6% with a ligamentous injury. The most frequently injured level was C6-7 (33%); C3-4 (6%) was least frequently involved. Sixty-four percent of patients were neurologically intact, 16% had incomplete spinal cord injuries (SCIs), 14% had complete SCIs, and three patients (6%) died after admission and before assessment. Treatment was conservative in 64%: seven (13%) wore a halo vest and 26 (51%) wore a rigid cervical orthosis. Surgery was performed in the other 18 patients (36%), with the breakdown as follows: 15 (30%) underwent an anterior approach, two (4%) had posterior approaches, and one (2%) had a combined approach. Postoperatively, four patients (8% who had a neurological deficit improved. The overall mortality rate was 8%; all deaths were related to MVAs. There were no surgery-related deaths or complications. CONCLUSIONS Subaxial cervical spine injuries are common in children 9 to 16 years of age, and occur principally between C-5 and C-7. Multilevel injury is more common in children 8 years of age and older than in younger children and infants. Most patients with subaxial cervical spine injuries can be treated conservatively. Both anterior and posterior approaches are safe and effective.

Abstract
Approximately 2% to 3% of blunt trauma victims suffer injury to the spinal column each year, often with devastating consequences. This article discusses clinical criteria for screening for spinal injury and the increasing roles of multidetector CT and MR imaging in the evaluation of spinal trauma. Both CT and MR imaging safety issues also are addressed. Lastly, the role of imaging in the evaluation of whiplash injury, instability, vascular injury, and delayed traumatic sequelae is discussed.
