Abstract
Most children receive emergency care by general emergency physicians and not in designated children's hospitals. There are unique considerations in the care of children that differ from the care of adults. Many management principles can be extrapolated from adult studies, but the unique pathophysiology of pediatric disease requires specialized attention and management updates. This article highlights ten impactful articles from the year 2023 whose findings can improve the care of children in the Emergency Department (ED). These studies address pediatric resuscitation, traumatic arrest, septic shock, airway management, nailbed injuries, bronchiolitis, infant fever, cervical spine injuries, and cancer risk from radiation (Table 1). The findings in these articles have the potential to impact the evaluation and management of children (Table 2).

Abstract
BACKGROUND Paediatric cervical spine injury (CSI) after blunt trauma is rare but can have severe consequences. Clinical decision rules (CDRs) have been developed to guide clinical decision-making, minimise unnecessary tests and associated risks, whilst detecting all significant CSIs. Several validated CDRs are used to guide imaging decision-making in adults following blunt trauma and clinical criteria have been proposed as possible paediatric-specific CDRs. Little information is known about their accuracy. OBJECTIVES To assess and compare the diagnostic accuracy of CDRs or sets of clinical criteria, alone or in comparison with each other, for the evaluation of CSI following blunt trauma in children. SEARCH METHODS For this update, we searched CENTRAL, MEDLINE, Embase, and six other databases from 1 January 2015 to 13 December 2022. As we expanded the index test eligibility for this review update, we searched the excluded studies from the previous version of the review for eligibility. We contacted field experts to identify ongoing studies and studies potentially missed by the search. There were no language restrictions. SELECTION CRITERIA We included cross-sectional or cohort designs (retrospective and prospective) and randomised controlled trials that compared the diagnostic accuracy of any CDR or clinical criteria compared with a reference standard for the evaluation of paediatric CSI following blunt trauma. We included studies evaluating one CDR or comparing two or more CDRs (directly and indirectly). We considered X-ray, computed tomography (CT) or magnetic resonance imaging (MRI) of the cervical spine, and clinical clearance/follow-up as adequate reference standards. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts for relevance, and carried out eligibility, data extraction and quality assessment. A third review author arbitrated. We extracted data on study design, participant characteristics, inclusion/exclusion criteria, index test, target condition, reference standard and data (diagnostic two-by-two tables) and calculated and plotted sensitivity and specificity on forest plots for visual examination of variation in test accuracy. We assessed methodological quality using the Quality Assessment of Diagnostic Accuracy Studies Version 2 tool. We graded the certainty of the evidence using the GRADE approach. MAIN RESULTS We included five studies with 21,379 enrolled participants, published between 2001 and 2021. Prevalence of CSI ranged from 0.5% to 1.85%. Seven CDRs were evaluated. Three studies reported on direct comparisons of CDRs. One study (973 participants) directly compared the accuracy of three index tests with the sensitivities of NEXUS, Canadian C-Spine Rule and the PECARN retrospective criteria being 1.00 (95% confidence interval (CI) 0.48 to 1.00), 1.00 (95% CI 0.48 to 1.00) and 1.00 (95% CI 0.48 to 1.00), respectively. The specificities were 0.56 (95% CI 0.53 to 0.59), 0.52 (95% CI 0.49 to 0.55) and 0.32 (95% CI 0.29 to 0.35), respectively (moderate-certainty evidence). One study (4091 participants) compared the accuracy of the PECARN retrospective criteria with the Leonard de novo model; the sensitivities were 0.91 (95% CI 0.81 to 0.96) and 0.92 (95% CI 0.83 to 0.97), respectively. The specificities were 0.46 (95% CI 0.44 to 0.47) and 0.50 (95% CI 0.49 to 0.52) (moderate- and low-certainty evidence, respectively). One study (270 participants) compared the accuracy of two NICE (National Institute for Health and Care Excellence) head injury guidelines; the sensitivity of the CG56 guideline was 1.00 (95% CI 0.48 to 1.00) compared to 1.00 (95% CI 0.48 to 1.00) with the CG176 guideline. The specificities were 0.46 (95% CI 0.40 to 0.52) and 0.07 (95% CI 0.04 to 0.11), respectively (very low-certainty evidence). Two additional studies were indirect comparison studies. One study (3065 participants) tested the accuracy of the NEXUS criteria; the sensitivity was 1.00 (95% CI 0.88 to 1.00) and specificity was 0.20 (95% CI 0.18 to 0.21) (low-certainty evidence). One retrospective study (12,537 participants) evaluated the PEDSPINE criteria and found a sensitivity of 0.93 (95% CI 0.78 to 0.99) and specificity of 0.70 (95% CI 0.69 to 0.72) (very low-certainty evidence). We did not pool data within the broader CDR categories or investigate heterogeneity due to the small quantity of data and the clinical heterogeneity of studies. Two studies were at high risk of bias. We identified two studies that are awaiting classification pending further information and two ongoing studies. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the diagnostic test accuracy of CDRs to detect CSIs in children following blunt trauma, particularly for children under eight years of age. Although most studies had a high sensitivity, this was often achieved at the expense of low specificity and should be interpreted with caution due to a small number of CSIs and wide CIs. Well-designed, large studies are required to evaluate the accuracy of CDRs for the cervical spine clearance in children following blunt trauma, ideally in direct comparison with each other.

Abstract
Traffic accidents involving children and adolescents present complex challenges from both the medico-legal and orthopedic standpoints. Despite the implementation of road traffic safety laws, pediatric road traffic injuries continue to be a significant contributor to mortality rates, physical harm, and hospitalization on a global scale. For children and young people, automobile accidents are considered to be the primary culprit of mortality in developed nations. Even in highly developed nations, trauma is a significant factor in infant mortality. Each age category, from childhood to young adulthood, has its fracture patterns, as their skeletons are considerably different from those of adults. The consequences of traffic accidents extend beyond the immediate physical trauma. The medico-legal aspects surrounding these incidents add another layer of complexity, as legal repercussions may affect the responsible adult or parent, particularly in cases involving child fatalities. To effectively address traffic accidents in children and adolescents, a comprehensive approach is necessary. This approach should involve not only medical professionals but also legal experts and policymakers. Collaboration between orthopedic specialists, medico-legal professionals, law enforcement agencies, and relevant government bodies can facilitate the development and implementation of strategies aimed at prevention, education, the enforcement of traffic laws, and improved infrastructure. By addressing both the medical and legal aspects, it is possible to enhance road safety for children and adolescents, reducing the incidence of injuries and their associated long-term consequences. In this review, we aimed to summarize traffic accidents in children and adolescents from a complex orthopedic and medico-legal approach.

Abstract
A 6-year-old girl presented with a one-week history of neck pain after a trampoline accident. Cervical radiographs interpreted as pseudosubluxation of C2 on C3. CT demonstrated the reversal of lordosis with anterolisthesis of C2-C3 and C3-C4. Ten weeks after two months of halo traction, radiographs demonstrated anatomic alignment and maintained disk heights. This case highlights the similarities of pseudosubluxation and true injury, emphasizing the need for high index of suspicion in this population and a successful treatment of subluxation using a halo construct.

Abstract
Acute myelopathy presenting in childhood can be clinically classified based on the location of injury (with resulting spinal syndrome) or the cause (broadly traumatic or non-traumatic). Types of nontraumatic myelopathy include ischaemic, infectious, inflammatory, nutritional, and metabolic causes, some of which may be part of a systemic illness such as systemic lupus erythematosus or a demyelinating disease such as multiple sclerosis. Nonaccidental injury is an important consideration in cases of traumatic myelopathy, which may often be associated with other injuries. Assessment should include neuroimaging of the brain and spinal cord, with further investigations targeted based on the most likely differential diagnoses; for example, a child with suspected demyelinating disease may require specialist cerebrospinal fluid and serological testing. Management also will differ based on the cause of the myelopathy, with several of these treatments more efficacious with earlier initiation, necessitating prompt recognition, diagnosis, and treatment of children presenting with symptoms of a myelopathy. Important components of holistic care may include physiotherapy and occupational therapy, with multidisciplinary team involvement as required (for example psychological support or specialist bowel and bladder teams).

Abstract
Background and aim: Considering the high rate of mortality and permanent disability related to vertebral traumas, an early and detailed diagnosis of the trauma and subsequently an immediate and effective intervention are crucial. Cervical vertebral injury classifications guide treatment choice through a severity grade based on radiological information. The purpose of the present study was to define which imaging classification system could provide the best morphological and clinical-surgical correlations for cervical spine traumas. Methods: We retrospectively analyzed patients evaluated for cervical spine trauma at our Institution in the period 2015-2020. Information regarding the morphological examination (using CT and MRI), the neurological evaluation, and the therapeutic management were collected. C3-C7 fractures were classified according to the SLIC and AOSpine criteria; axial lesions were classified according to the modified AOSpine for the C1-C2 compartment and through the Roy-Camille and the Anderson D’Alonzo system for the odontoid process of the axis. Results: 29 patients were included in the final study population. Nine patients with axial spine trauma and 21 with subaxial cervical spine trauma. A conservative approach was applied in 16 patients while nine patients underwent neurosurgery. Considering the therapeutical indications provided by the SLIC system, a 76.9% accordance was found for patients with a <4 score, while a 100% concordance was calculated for patients with a >4 score undergoing neurosurgery. Regarding the AOSspine classification, a 28.6% concordance was observed for patients classified group B being treated with a posterior neurosurgical approach, while for patients belonging to subgroup C, considered for anterior neurosurgical approach, a 66.7% accordance was calculated. Conclusions: The study demonstrated a better morphological correlation for the AOSpine classification in subaxial trauma and the AOSpine and Anderson D’Alonzo in axial trauma. The therapeutic indication found a better correlation in the SLIC classification for subaxial trauma and the Anderson D’Alonzo for axial ones. (www.actabiomedica.it)

Abstract
Cervical spine (C-spine) fractures in young children are very rare, and little information on treatment modalities and functional, radiographic, and patient-reported outcome exists. In this 2-center, retrospective case series, we assessed subjective and functional mid-term outcomes in children aged ≤5 years whose C-spine fractures were treated nonoperatively.Between 2000 and 2018, 6 children (median age at injury: 23.5 months; range: 16-31 months) with C1 or C2 injuries were treated with Minerva cast/brace or soft collar brace at 1 of the 2 study centers. Two patients suffered C1 fractures, and 4 patients had lysis of the odontoid synchondrosis. Overall, 3 children had sustained polytrauma. One child died due to the consequences of massive head injury.For the primary outcome parameter, we recorded subjective symptoms such as pain and functional restrictions due to the sequelae of C-spine injuries at follow-up.Based on medical records, we also assessed the causes of injury, diagnostic procedures, treatments and complications, and time to fracture consolidation.Median follow-up of the 5 surviving children was 51 months (range: 36-160 months). At the latest follow-up, 4 of 5 children did not complain of any pain. One child who sustained an open head injury in combination with a subluxation of the odontoid and undisplaced fracture of the massa lateralis reported occasional headache. All patients experienced complete fracture healing and normal range of motion of the cervical spine.Median duration of cast/brace treatment was 8.5 weeks. Fracture healing was confirmed by computed tomography in all patients.All C-spine injuries were managed with either Minerva cast/Halo brace or soft collar brace without complications.In our retrospective case series, nonoperative treatment of atlas fractures and dislocations or subluxations of the odontoid in young children using Minerva casts or prefabricated Halo braces resulted in good subjective and functional outcomes at mid-term. We observed no complications of conservative treatment of C1 and C2 injuries in young children.

Abstract
BACKGROUND AND OBJECTIVE Characterizing the mechanical properties of the cancellous bone from the cervical vertebrae of child or child surrogate is important for the development of spine finite element models and the investigation of injury mechanism, however, there is currently no public data available as far as we know. METHODS Compression tests were conducted on the specimens from the cervical vertebrae of 8-week-old piglets (child surrogates) in axial and radial directions at the strain rates of 0.01, 0.1, 1 and 10/s. The influences of directionality and strain rate on the mechanical properties of the vertebral cancellous bone were statistically investigated. The typical transversely isotropic model, which was added a strain rate item and a plasticity item, was implemented into LS-DYNA finite element code. Based on the material subroutine code, simulation was conducted on the vertebral tissue under compression in axial and radial directions at different strain rates. RESULTS The mechanical properties of the cancellous bone of cervical vertebrae were obtained and most of the stress-strain curves showed major linear elastic stage and short plastic stage before fracture. Significant anisotropic behavior was observed for the vertebral tissue in axial and radial directions. The elastic modulus, ultimate stress,yield stress, and ultimate strain of the speimens in axial direction was obtained, with on average, 2.5 ± 0.6 times, 2.1 ± 0.15 times, and 2.1 ± 0.1 times higher and 0.86 ± 0.076 times lower respecitvely, than those in radial direction. In addition, with the strain rate varying from 0.01/s to 10/s, the mechanical parameters, like elastic modulus, yield and ultimte stresses exhibited significant strain rate effect, however, no significant difference was found for the ultimate strain. CONCLUSIONS The cervical vertebrae showed significant anisotropic and strain rate-dependent behaviors. The self-developed subroutine codes based on the strain rate-dependent transversely isotropic elastic and plastic constitutive model can simulate the behaviors well.

Abstract
PURPOSE Pediatric cervical spine injuries are rare events. Missed injuries must be weighed against radiation exposure and excess resource utilization in a young population. A universal pediatric cervical spine clearance algorithm does not exist. The study objective is to determine if care improved after the implementation of a standardized cervical spine clearance pathway by evaluating imaging rates, length of stay, speciality consultation, and injury detection. METHODS A multidisciplinary group reviewed relevant literature to develop an algorithm for cervical spine clearance in pediatric trauma patients. We reviewed patient charts 15 months before and after implementation. Categorical comparisons were tested with Chi-square. A p value less than 0.05 was considered statistically significant. RESULTS The pre- and post-implementation groups were homogenous when comparing demographics, mechanism and severity of injury. Using the cervical spine clearance pathway, patients received fewer plain cervical spine radiographs (34% vs 16%), fewer spine speciality consults (28% vs 13%), and more patients were cleared clinically (44% vs 62%) (p < 0.05). There were 2 (1.7%) documented injuries in the pre-implementation group and 3 (3%) documented injuries in the post-implementation group. There were no missed injuries. CONCLUSIONS Use of a standardized pathway allows more patients' cervical spines to be cleared clinically and better utilizes resources without compromising patient care. LEVEL OF EVIDENCE Level III. TYPE OF STUDY Care Management Study.

Abstract
BACKGROUND AND OBJECTIVE The cervical spine is one of the primary regions that is easily injured in traffic accidents. Although adult cervical spine finite element models have been widely adopted to investigate the cervical injury, few efforts have been made with respect to the development and application of FE models of the pediatric cervical spine, especially that of a six-year-old child. The objective of this study is to develop and validate high quality cervical spinal segment C6-C7 FE models of a six-year-old child and an adult, and to further investigate the differences of C6-C7 between the child and adult under different loading conditions. METHODS The cervical spinal segment C6-C7 FE models were developed by a structured multiblock method, and were verified under flexion, extension, axial rotation, and lateral bending conditions. The validated models were used to investigate the differences of C6-C7 between the child and adult under different loading conditions. RESULTS The global angular displacement of C6-C7, the ligament elongation ratio, and the maximum effective strain of annulus fibrosus of the child were obviously larger than those of the adult under the same loading conditions. Regarding the loading forms, the flexion angular displacement of C6-C7 of the child was obviously larger than those of the extension and lateral bending, while for the adult cervical segment C6-C7, no obvious differences existed. The elongation ratio of different ligaments was highly dependent on the types of loadings. The maximum effective strain of annulus fibrosus under flexion, extension and lateral bending loads occurred at the compressive region of the front, rear, and one compressive lateral side, in which the annulus fibrosus was more susceptible to injury under the lateral bending condition, compared with those of the flexion and extension conditions. CONCLUSIONS Both the developed child and adult cervical spinal segment C6-C7 FE models exhibited high biofidelity. The responses (angular displacement, the ligament elongation ratio, and the maximum effective strain of annulus fibrosus) of the child and adult are dependent on the loading types, and the responses of the child were obviously larger than those of the adult under the same loading conditions.

Abstract
CONTEXT Pediatric traumatic spinal cord injury (SCI) is an uncommon presentation in the emergency department. Severe injuries are associated with devastating outcomes and complications, resulting in high costs to both the society and the economic system. EVIDENCE ACQUISITION The data on pediatric traumatic spinal cord injuries has been narratively reviewed. RESULTS Pediatric SCI is a life-threatening emergency leading to serious outcomes and high mortality in children if not managed promptly. Pediatric SCI can impose many challenges to neurosurgeons and caregivers because of the lack of large studies with high evidence level and specific guidelines in terms of diagnosis, initial management and of in-hospital treatment options. Several novel potential treatment options for SCI have been developed and are currently under investigation. However, research studies into this field have been limited by the ethical and methodological challenges. CONCLUSION Future research is needed to investigate the safety and efficacy of the recent uprising neurodegenerative techniques in SCI population. Owing to the current limitations, there is a need to develop novel trial methodologies that can overcome the current methodological and ethical limitations.

Abstract
BACKGROUND Atlanto-axial rotatory fixation (AARF) is an uncommon condition in children presenting with torticollis. Many studies have elaborated on the diagnostic sequence of AARF. However, there is no consensus for the algorithm of management of AARF. METHODS This study proposes to provide a comprehensive step-by-step guideline which aims to achieve and retain anatomic reduction of the atlanto-axial joint (AAJ). We recommend a 'therapeutic crescendo': closed reduction and immobilization in a rigid cervical collar (step I). In cases of re-dislocation, a second attempt of closed reduction and immobilization in a Halo-jacket (step II). Cases of recurrent dislocations due to persistent instability require open reduction and internal fixation. We present a new surgical technique of transverse suture transfixation (TSF) of C1/C2 (step III). Alternatively, a dorsal stabilization of C1/C2 is indicated after open reduction (step IV). 13 patients with radiologically confirmed AARF were included in this study. These patients were treated as per the above mentioned algorithm. All these patients were serially evaluated with a minimum follow-up of 1 year. RESULTS Clinical data of 10/13 patients were available for follow-up evaluation at mean 4.6 years after the onset of symptoms. Two patients were managed surgically. We recorded good clinical results in all patients treated according to the algorithm. CONCLUSIONS AARF is a subacute pediatric emergency. Reduction and maintenance of joint congruency of the AAJ are the treatment goals. The comprehensive therapeutic algorithm presented in this study is applicable in patients with AARF to achieve excellent long-term results. LEVEL OF EVIDENCE IV, Retrospective cohort study.

Abstract
Introduction Odontoid fractures in young children are rare. Most authors advocate for closed reduction and external stabilization as first line treatment. Unlike adults, young children are much less amenable to an awake reduction for real-time assessment of neurological function. We used spinal cord monitoring, as used in spine surgery, to assess the function of the spinal cord during the closed reduction in our 31-month-old patient. Case presentation A 31-month-old male presented with a displaced odontoid fracture and ASIA C spinal cord injury. Given his age, closed reduction and halo application were completed under general anesthesia guided by neuromonitoring. A less-than-ideal reduction initially was accepted due to a decline in motor-evoked potentials. Subsequently, there was no change in neurological status. The reduction was repeated under anesthesia, with monitoring, a number of times until good correction was achieved. Ultimately, a surgical fusion was required due to ligamentous instability. The child achieved a very good neurological outcome and a stable spine. Discussion Neuromonitoring is an important adjunct to closed reductions when complete and reliable neurological assessment is not possible.

Abstract
Introduction Paediatric cervical spine injuries are uncommon. Traumatic spondylolisthesis of the axis (TSA) is commonly encountered in the trauma setting. The management of TSA may be surgical or non-surgical. Decision making is quite challenging depending on patient presentation and nature of injury, and even more so in the paediatric age group. Objectives To present a case report highlighting the challenges in the management of TSA. Methods We present an 8 year old male, who sustained a bilateral C2 pars fracture with associated unusual C2-C3 posterior subluxation. Results Neuroradiological studies identified the fracture/subluxation of C2-C3 and revealed an intact but posteriorly displaced C2-C3 disc causing cord compression. An Extension Halter traction was initially commenced. This seemed to have worsened the patient's neck pains, and caused motor weakness and autonomic dysfunction. An anterior cervical discectomy and fusion was finally decided on and performed after evaluation and brainstorming by our spinal Unit. Intra-operative findings revealed separation of the C2-C3 disc from the C3 superior end plate which probably explains the unusual nature of the subluxation. Conclusion The case shows that surgical intervention as a primary management for TSA even in the paediatric age group is safe and also avoids risks inherent in conservative management.

Abstract
Multiply injured child is a unique challenge to the medical communities worldwide. It is a leading cause of preventable mortality and morbidity in children. Common skeletal injuries include closed or open fractures of tibia and femur and pelvic injuries. Initial management focuses on saving life and then saving limb as per pediatric advanced life support and advanced trauma life support. Orthopedic management of open fracture includes splinting the limb, administration of prophylactic antibiotic, and surgical debridement of the wound when safe. However, gross contamination, compartment syndrome, and vascular injuries demand urgent attention.

Abstract
Background Paediatric spinal injury is rare and exhibits many unique features. Attending clinicians and radiologists often lack knowledge, expertise and experience in dealing with a potential injury to the paediatric spine. Within the paediatric age range itself there are different age-dependent mechanisms that can injure the paediatric spine. Moreover, the anatomical features and degree of osseous maturity of the developing paediatric spine determine the biomechanical characteristics which promote unique patterns of spinal injury in each paediatric age group. Methods An expert illustrated narrative review of the literature. Results Multiple factors make the imaging interpretation of the injured paediatric spine challenging. Each imaging modality has strengths and weaknesses in depicting spinal anatomy which vary with the type of spinal injury and age of the paediatric patient. Conclusions Attending doctors need to be familiar with the imaging appearances of the normal paediatric spine, its normal variants as well as the imaging features characteristics of paediatric spinal injury seen on radiographs, computed tomography and magnetic resonance imaging.

Abstract
BACKGROUND It is crucial to identify cervical spine injuries while minimizing ionizing radiation. This study analyzes the sensitivity and negative predictive value of a pediatric cervical spine clearance algorithm. METHODS We performed a retrospective review of all children <21years old who were admitted following blunt trauma and underwent cervical spine clearance utilizing our institution's cervical spine clearance algorithm over a 10-year period. Age, gender, International Classification of Diseases 9th Edition diagnosis codes, presence or absence of cervical collar on arrival, Injury Severity Score, and type of cervical spine imaging obtained were extracted from the trauma registry and electronic medical record. Descriptive statistics were used and the sensitivity and negative predictive value of the algorithm were calculated. RESULTS Approximately 125,000 children were evaluated in the Emergency Department and 11,331 were admitted. Of the admitted children, 1023 patients arrived in a cervical collar without advanced cervical spine imaging and were evaluated using the cervical spine clearance algorithm. Algorithm sensitivity was 94.4% and the negative predictive value was 99.9%. There was one missed injury, a spinous process tip fracture in a teenager maintained in a collar. CONCLUSIONS Our algorithm was associated with a low missed injury rate and low CT utilization rate, even in children <3years old. LEVEL OF EVIDENCE IV.

Abstract
Traumatic brain injuries (TBIs) in children are a major cause of morbidity and mortality worldwide. Severe TBIs account for 15,000 admissions annually and a mortality rate of 24% in children in the United States. The purpose of this article is to explore pathophysiologic events, examine monitoring techniques, and explain current treatment modalities and nursing care related to caring for children with severe TBI. The primary injury of a TBI is because of direct trauma from an external force, a penetrating object, blast waves, or a jolt to the head. Secondary injury occurs because of alterations in cerebral blood flow, and the development of cerebral edema leads to necrotic and apoptotic cellular death after TBI. Monitoring focuses on intracranial pressure, cerebral oxygenation, cerebral edema, and cerebrovascular injuries. If abnormalities are identified, treatments are available to manage the negative effects caused to the cerebral tissue. The mainstay treatments are hyperosmolar therapy; temperature control; cerebrospinal fluid drainage; barbiturate therapy; decompressive craniectomy; analgesia, sedation, and neuromuscular blockade; and antiseizure prophylaxis.

Abstract
Although a number of finite element (FE) adult cervical spine models have been developed to understand the injury mechanisms of the neck in automotive related crash scenarios, there have been fewer efforts to develop a child neck model. In this study, a 10-year-old ligamentous cervical spine FE model was developed for application in the improvement of pediatric safety related to motor vehicle crashes. The model geometry was obtained from medical scans and meshed using a multi-block approach. Appropriate properties based on review of literature in conjunction with scaling were assigned to different parts of the model. Child tensile force–deformation data in three segments, Occipital-C2 (C0–C2), C4–C5 and C6–C7, were used to validate the cervical spine model and predict failure forces and displacements. Design of computer experiments was performed to determine failure properties for intervertebral discs and ligaments needed to set up the FE model. The model-predicted ultimate displacements and forces were within the experimental range. The cervical spine FE model was validated in flexion and extension against the child experimental data in three segments, C0–C2, C4–C5 and C6–C7. Other model predictions were found to be consistent with the experimental responses scaled from adult data. The whole cervical spine model was also validated in tension, flexion and extension against the child experimental data. This study provided methods for developing a child ligamentous cervical spine FE model and to predict soft tissue failures in tension.

Abstract
Cervical spinal column injuries occur uncommonly in infants and young toddlers, and rarely in the upper cervical spine. Any injury, when discovered at forensic autopsy, must be interpreted within the context of a complete case investigation, and available science. When severe upper cervical spinal column injury is detected, such as atlanto-occipital dislocation (AOD), atlanto-axial dislocation (AAD) or spinal cord transection, forensic pathologists commonly regard such trauma as a marker of significant forces. This retrospective study evaluated 60 cases of accidental and homicidal deaths occurring in the first 24 months of life and investigated by a large metropolitan medical examiner jurisdiction. All cases with AOD, AAD or spinal cord transection occurred under documented accidental circumstances, and all of those cases involved severe forces, including being struck by or run over by a car. While such high cervical spinal column pathology is not unusual when an infant or young toddler is struck by or run over by a motor vehicle, or other accidental circumstance involving severe forces, this discovery in a case of apparent natural death or death following alleged short fall or other commonplace activity of daily living should be considered highly suspect.

Abstract
![]()
This Grand Rounds is about the clinical and radiological presentation, treatment and outcome of pediatric cervical spine injury. A 15-month-old girl suffers from a motor vehicle accident and is intubated on-site because of progressive agitation. Whole body trauma CT was read as normal. When sedation was discontinued after 24 h she was found to be tetraplegic below C6 level. MRI shows a total disruption between C6 and C7 that in hindsight was also visible on the initial trauma CT. She was treated surgically by an anterior and posterior reconstruction and was post-operatively treated with a halo vest. Clearing the cervical spine in young children is deceptively difficult. Meticulous review and interpretation of conventional radiographs and CT are important yet MRI should be considered in uncertain cases. Severe ligamentous injury without concomitant bony injury occurs more frequently than in older children and adults, with sometimes devastating consequences.

Abstract
INTRODUCTION Plain radiographs continue to play a role in cervical spine clearance. Inadequate radiographs commonly necessitate repeat x-rays or computed tomography imaging (10 × radiation dose). We have used the technique of cephalic stabilization (CS) to improve the results of plain radiographs. Cephalic stabilization lateral radiographs are obtained, with one assistant applying traction to the arms while another placing fingers in the patient's ears and stabilizing the head. This study tests the hypothesis that CS improves visualization of the cervicothoracic junction during lateral cervical spine radiographs. METHODS A 2-year review of institutional pediatric trauma registry identified 46 patients with CS, matched 1:3 with controls. Randomized lateral radiographs were evaluated independently by 2 pediatric radiologists to determine adequate visualization of the craniocervical and cervicothoracic junctions. Reviewers were blinded to CS through image cropping. RESULTS The proportion of adequate visualization of the cervicothoracic junction was 0.85 for cases with stabilization and 0.60 for controls. Odds of obtaining adequate visualization with stabilization are 3.8 times those without stabilization (P = .001) and were even greater for patients younger than 13 years. CONCLUSIONS Cephalic stabilization improves visualization of the cervicothoracic junction in lateral cervical spine radiographs and can reduce radiation exposure in patients who would otherwise require further imaging.

Abstract
OBJECTIVE: To outline a profile of pediatric trauma victims and verify the likelihood of trauma in children on a high traffic roadway. METHODS: A descriptive cohort study of the records of emergency medical service activations on the Rio-Niterói Bridge, a high traffic roadway in Rio de Janeiro, Brazil. Descriptive statistics were expressed as absolute and relative frequencies. The estimated risk of trauma in children aged < 12 years was calculated by means of odds ratios, with a 95% confidence interval. RESULTS: Trauma accounted for 514 of 1,244 activations (41.31%) of the Rio-Niterói Bridge emergency medical service between March 2002 and March 2003. Response to incidents involving children aged < 12 years accounted for 52 of these (4.18%). Half of victims were between the ages of 6 and 12 years (n = 26), and 55.76% were male (n = 29). Of the 52 victims, 37 (71.15%) were involved in motor vehicle accidents (OR: 3.70; 95%CI: 1.94-7.13; p < 0.0001). Of these, 28 were vehicle-vehicle collisions (75.67%). The most common sites of injury were the extremities (n = 12; 32.43%), face (n = 10; 27.02%), and head (n = 9; 24.32%). Pre-hospital procedures were performed on 23 of the 37 patients (62.16%), and 44.23% (n = 23/52) required hospital transportation. There were no deaths during the study period. CONCLUSIONS: In this study, children were at significantly higher odds of being treated for trauma while on a highway with heavy traffic flow. The most common sites of injury in this sample were the lower extremities and the head, face, and neck complex.

Abstract
OBJECTIVES The objectives were to identify patient and hospital characteristics associated with the use of computed tomography (CT) imaging of the cervical spine (c-spine) in the evaluation of injured children and, in particular, to examine the influence of hospital setting. METHODS This was a retrospective cohort of children younger than 19 years of age from the Massachusetts Hospital Emergency Department (ED) database who were discharged from the ED with an injury diagnosis from 2005 through 2009. Multivariable logistic regression was used to analyze characteristics associated with CT imaging of the c-spine. RESULTS Of the 929,626 pediatric patients diagnosed with an injury in Massachusetts EDs and then discharged home, 1.3% underwent CT imaging of the c-spine. Rates of CT imaging nearly doubled over the 5 years. In the multivariable model, patient age (adjusted odds ratio [AOR] = 2.3, 95% confidence interval [CI] = 2.0 to 2.7 for children age 12 to 18 years vs. under 1 year of age) and evaluation outside of a pediatric Level I trauma center (AOR = 2.2, 95% CI = 1.1 to 4.3 for children evaluated at non Level I trauma centers vs. pediatric Level I trauma centers; AOR = 2.1, 95% CI = 0.93 to 4.7 for children evaluated at adult Level I trauma centers vs. pediatric Level I trauma centers) were associated with higher rates of CT imaging of the c-spine. CONCLUSIONS Cervical spine CT imaging for children discharged from the ED with trauma diagnoses increased from 2005 through 2009. Older age and evaluation outside a Level I pediatric trauma center were associated with a higher c-spine CT rate. Educational interventions focused outside pediatric trauma centers may be an effective approach to decreasing CT imaging of the c-spine of pediatric trauma patients.

Abstract
Injuries to the spinal column and cord in children are a rare condition. Epidemiological data could help to establish an evidence-based assessment and therapy of these patients. We present a retrospective chart analysis of children with spinal injuries who were admitted to the emergency room. The patients were analyzed regarding age, mechanism, and distribution of their injuries to all spinal regions and treatment strategies. Thirty-five children met the inclusion criteria with severe spinal injuries (Abbreviated Injury Scale [AIS] for Region 6 [spine]; AIS region 6) in a period from January 2003 to December 2009. The incidence was extremely low in younger children, with increasing numbers during adolescence. Neurological deficit without fracture accounted for almost 25% of all patients. The majority of patients were treated conservatively; operative treatment was performed in 25% of patients with unstable fractures, particularly in adolescents. Treatment strategies differ according to the type and degree of injury, age, and level of spine maturation.
