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
The clinical presentation and diagnostic workup in pediatric cervical spine injuries (CSI) are different from adults owing to the unique anatomy and relative immaturity. The current article reviews the existing literature regarding the uniqueness of these injuries and discusses the current guidelines of radiological evaluation. A PubMed search was conducted using keywords "paediatric cervical spine injuries" or "paediatric cervical spine trauma." Six hundred and ninety two articles were available in total. Three hundred and forty three articles were considered for the review after eliminating unrelated and duplicate articles. Further screening was performed and 67 articles (original articles and review articles only) related to pediatric CSI were finally included. All articles were reviewed for details regarding epidemiology, injury patterns, anatomic considerations, clinical, and radiological evaluation protocols. CSIs are the most common level (60%-80%) for pediatric Spinal Injuries (SI). Children suffer from atlantoaxial injuries 2.5 times more often than adults. Children's unique anatomical features (large head size and highly flexible spine) predispose them to such a peculiar presentation. The role of National Emergency X-Ray Utilization Study, United State (NEXUS) and Canadian Cervical Spine Rule criteria in excluding pediatric cervical injury is questionable but cannot be ruled out completely. The minimum radiological examination includes 2- or 3-view cervical X-rays (anteroposterior, lateral ± open-mouth odontoid views). Additional radiological evaluations, including computerized tomography (CT) and magnetic resonance imaging (MRI) are obtained in situations of abnormal physical examination, abnormal X-rays, inability to obtain adequate X-rays, or to assess cord/soft-tissue status. The clinical criteria for cervical spine injury clearance can generally be applied to children older than 2 years of age. Nevertheless, adequate caution should be exercised before applying these rules in younger children. Initial radiographic investigation should be always adequate plain radiographs of cervical spine. CT and MRI scans should only be performed in an appropriate group of pediatric patients.

Abstract
BACKGROUND Pediatric cervical spine injury (CSI) after blunt trauma is rare. Nonetheless, missing these injuries can have severe consequences. To prevent the overuse of radiographic imaging, two clinical decision tools have been developed: The National Emergency X-Radiography Utilization Study (NEXUS) criteria and the Canadian C-spine Rule (CCR). Both tools are proven to be accurate in deciding whether or not diagnostic imaging is needed in adults presenting for blunt trauma screening at the emergency department. However, little information is known about the accuracy of these triage tools in a pediatric population. OBJECTIVES To determine the diagnostic accuracy of the NEXUS criteria and the Canadian C-spine Rule in a pediatric population evaluated for CSI following blunt trauma. SEARCH METHODS We searched the following databases to 24 February 2015: CENTRAL, MEDLINE, MEDLINE Non-Indexed and In-Process Citations, PubMed, Embase, Science Citation Index, ProQuest Dissertations & Theses Database, OpenGrey, ClinicalTrials.gov, World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, the Health Technology Assessment, and the Aggressive Research Intelligence Facility. SELECTION CRITERIA We included all retrospective and prospective studies involving children following blunt trauma that evaluated the accuracy of the NEXUS criteria, the Canadian C-spine Rule, or both. Plain radiography, computed tomography (CT) or magnetic resonance imaging (MRI) of the cervical spine, and follow-up were considered as adequate reference standards. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the quality of included studies using the QUADAS-2 checklists. They extracted data on study design, patient characteristics, inclusion and exclusion criteria, clinical parameters, target condition, reference standard, and the diagnostic two-by-two table. We calculated and plotted sensitivity, specificity and negative predictive value in ROC space, and constructed forest plots for visual examination of variation in test accuracy. MAIN RESULTS Three cohort studies were eligible for analysis, including 3380 patients ; 96 children were diagnosed with CSI. One study evaluated the accuracy of the Canadian C-spine Rule and the NEXUS criteria, and two studies evaluated the accuracy of the NEXUS criteria. The studies were of moderate quality. Due to the small number of included studies and the diverse outcomes of those studies, we could not describe a pooled estimate for the diagnostic test accuracy. The sensitivity of the NEXUS criteria of the individual studies was 0.57 (95% confidence interval (CI) 0.18 to 0.90), 0.98 (95% CI 0.91 to 1.00) and 1.00 (95% CI 0.88 to 1.00). The specificity of the NEXUS criteria was 0.35 (95% CI 0.25 to 0.45), 0.54 (95% CI 0.45 to 0.62) and 0.2 (95% CI 0.18 to 0.21). For the Canadian C-spine Rule the sensitivity was 0.86 (95% CI 0.42 to 1.00) and specificity was 0.15 (95% CI 0.08 to 0.23). Since the quantity of the data was small we were not able to investigate heterogeneity. AUTHORS' CONCLUSIONS There are currently few studies assessing the diagnostic test accuracy of the NEXUS criteria and CCR in children. At the moment, there is not enough evidence to determine the accuracy of the Canadian C-spine Rule to detect CSI in pediatric trauma patients following blunt trauma. The confidence interval of the sensitivity of the NEXUS criteria between the individual studies showed a wide range, with a lower limit varying from 0.18 to 0.91 with a total of four false negative test results, meaning that if physicians use the NEXUS criteria in children, there is a chance of missing CSI. Since missing CSI could have severe consequences with the risk of significant morbidity, we consider that the NEXUS criteria are at best a guide to clinical assessment, with current evidence not supporting strict or protocolized adoption of the tool into pediatric trauma care. Moreover, we have to keep in mind that the sensitivity differs among several studies, and individual confidence intervals of these studies show a wide range. Our main conclusion is therefore that additional well-designed studies with large sample sizes are required to better evaluate the accuracy of the NEXUS criteria or the Canadian C-spine Rule, or both, in order to determine whether they are appropriate triage tools for the clearance of the cervical spine in children following blunt trauma.

Abstract
PURPOSE Spinal injuries are rarely seen in pediatric patients and therapeutic options are still poorly defined. The present study is aimed to present our experience with a rather large series of children and young adults suffering from traumatic spinal injury. PATIENTS AND METHODS Between 1990 and 2010, 75 consecutive pediatric patients with spinal injuries were treated in our institution. Mean age was 15 years, ranging from 3 months to 21 years. Radiological findings, treatment strategies, and clinical outcome were evaluated retrospectively and compared with literature. Forty (53.3%) patients were treated conservatively and 35 patients (47%) surgically using anterior or posterior approaches. Subgroup analysis was performed depending on age groups, severity of neurological symptoms, and localization. RESULTS Main trauma mechanisms were fall in 24 patients (38%) and motor vehicle accidents in 21 patients (28%). Complete neurological deficits were present in 17 individuals (23%) and incomplete in 36 patients (48%). Fractures were most frequently localized at the cervical region (56%) with predilection of the C 5/6 segment. Odontoid fractures were seen in 10 (13%) patients. Fractures of the lumbar and thoracic region were rare. Level of injury or clinical course did not differ between the subgroups (≤15 years versus >15 years). CONCLUSION Nearly three fourths of all radiologically detected spinal injuries are located at the cervical spine. Complete neurological deficits after trauma was associated with a poor outcome, in particular for patients with injuries of the upper cervical spine. The use of autologous bone graft was associated with favorable long-term results and should be considered as the material of first choice for vertebral body and disc replacement.

Abstract
The experience in airway management permits the anesthesiologist to participate in cases of cervical spine instability in the operating room when the patient is subjected to surgical procedures, or in cases of difficulty to access or keep the airway open in emergencies. This article reviews the epidemiology, definition, etiology, diagnostic criteria, methods of approach to airway management, and current recommendations on handling cervical instability in different scenarios. There is no approach to the airway that ensures complete immobility of the cervical spine, but there are methods that are better adapted to specific contexts; at the end, the reader will be able to identify the virtues and defects of the various options that the anesthesiologists have to address the airway in cases of cervical instability.

Abstract
About 5% of spinal injuries occur in children – however the consequences to the society are devastating, all the more so because the cervical spine is more commonly affected. Anatomical differences with adults along with the inherent elasticity of the pediatric spine, makes these injuries a biomechanically separate entity. Hence clinical manifestations are unique, one of which is the Spinal Cord Injury Without Radiological Abnormality. With the advent of high quality MRI and CT scan along with digital X-ray, it is now possible to exactly delineate the anatomical location, geometrical configuration, and the pathological extent of the injury. This has improved the management strategies of these unfortunate children and the role of surgical stabilization in unstable injuries can be more sharply defined. However these patients should be followed up diligently because of the recognized long term complications of spinal deformity and syringomyelia.

Abstract
Background Patients suffering from polytrauma often present with altered mental status and have varying levels of examinability. This makes evaluation difficult. Physicians are often required to rely on advanced imaging techniques to make prompt and accurate diagnoses. Occasionally, injury detection on advanced imaging studies can be challenging given the subtle findings associated with certain conditions, such as diffuse idiopathic skeletal hyperostosis (DISH). Delayed or missed diagnoses in the setting of spinal fracture can lead to catastrophic neurological injury. Case presentation A man struck by a motor vehicle suffered multiple traumatic injuries including numerous rib fractures, a mechanically unstable pelvic fracture, and also had suspicion for an aortic injury. Unfortunately, the upper thoracic segment (T1-5) was only visualized with axial images based on the electronic data. Several days later, a contrast CT scan obtained to check the status of suspected aortic injury revealed T3-T4 subluxation indicative of an unstable extension-type fracture in the setting of DISH. Due to the missed injury and delay in diagnosis, surgery was not performed until eight days after the injury. At surgery, the patient was found to have left T3-T4 facet joint infection as well as infected hematoma surrounding a left T4 transverse process fracture and a traumatic T4 costo-transverse joint fracture-subluxation. Despite presence of infection, an instrumented posterior spinal fusion from T1-T6 was performed and the patient recovered well after antibiotic treatment. Conclusion A T3-T4 unstable DISH extension-type fracture was initially missed in a polytrauma patient due to inadequate imaging acquisition, which caused a delay in treatment and bacterial seeding of fracture hematoma. Complete imaging is especially needed in obtunded patients that cannot be thoroughly examined.

Abstract
OBJECTIVE To provide certified athletic trainers, team physicians, emergency responders, and other health care professionals with recommendations on how to best manage a catastrophic cervical spine injury in the athlete. BACKGROUND The relative incidence of catastrophic cervical spine injury in sports is low compared with other injuries. However, cervical spine injuries necessitate delicate and precise management, often involving the combined efforts of a variety of health care providers. The outcome of a catastrophic cervical spine injury depends on the efficiency of this management process and the timeliness of transfer to a controlled environment for diagnosis and treatment. RECOMMENDATIONS Recommendations are based on current evidence pertaining to prevention strategies to reduce the incidence of cervical spine injuries in sport; emergency planning and preparation to increase management efficiency; maintaining or creating neutral alignment in the cervical spine; accessing and maintaining the airway; stabilizing and transferring the athlete with a suspected cervical spine injury; managing the athlete participating in an equipment-laden sport, such as football, hockey, or lacrosse; and considerations in the emergency department.

Abstract
OBJECTIVE The aim of this study is to determine the efficiency of artificial intelligence in detecting craniocervical junction injuries by using an artificial neural network (ANN) that may be applicable in future studies of different traumatic injuries. MATERIALS AND METHODS Major head trauma patients with Glasgow Coma Scale <or=8 of all age groups who presented to the Emergency Department were included in the study. All patients underwent brain computerized tomography (CT), craniocervical junction CT, and cervical plain radiography. A feedforward with back propagation ANN and a stepwise forward logistic regression were performed to test the performances of all models. RESULTS A total of 127 patients fulfilling inclusion criteria were included in the study. The mean age of the study patients was 31+/-17.7, 77.2% (n=98) of them were male, 13.4% of the patients (n=17) had craniocervical junction pathologies. About 64.7% (n=11) of these pathologies were detected only by CT; 23.5% (n=4) of them by both craniocervical CT and cervical plain radiography; and 11.8% (n=2) of them only by cervical plain radiography. A logistic regression model had a sensitivity of 11.8% and specificity of 99.1%. Positive predictive value was 66.7% and negative predictive value was 87.9%. Area under the curve for logistic regression model was 0.794 (P=0.000). ANN had a sensitivity of 82.4% and specificity of 100%. Positive predictive value was 100% and negative predictive value was 97.3%. Area under the curve for ANN model was 0.912 (P=0.000). CONCLUSION ANN as an artificial intelligence application seems appropriate for detecting and excluding craniocervical junction injury but it should not replace craniocervical junction CT. However, these findings should lead us to test the applicability of ANN on hard-to-diagnose trauma patients or in constructing clinical decision rules.

Abstract
BACKGROUND Clearance of the cervical spine after blunt trauma remains controversial in patients with normal radiologic evaluation. METHODS Blunt trauma patients with midline boney cervical tenderness and plain films that disclose no abnormalities and computed tomography (CT) scans were entered into a care pathway for spinal clearance using the Bolster or active range-of-motion (AROM) flexion/extension techniques. The quality of films between the two techniques was then compared. RESULTS In all, 159 patients entered the pathway with 14 patients (9%) unable to complete the examination secondary to pain. The Bolster was used in 129 patients (89%) and AROM was used in 16 (11%). The total range of motion was significantly better with AROM at 51.4 +/- 19.4 degrees of motion compared with 32.0 +/- 13.0 degrees with the Bolster (p < or = 0.05). The most distal level visualized was not different between groups with 6.6 +/- 0.8 cervical vertebrae visualized on average in the Bolster group and 6.8 +/- 0.7 in the AROM group. Positive findings occurred in five patients (3.4%) in the Bolster group. CONCLUSION The incidence of occult cervical injury in patients with boney cervical pain despite normal plain films and CT scans in this study was 3.4%. The AROM technique has better total range of motion than the Bolster, although results of the Bolster technique remain within acceptable standards. The present care pathway appears to be an effective screening tool for evaluation of this population of patients. Additional evaluation of the obtunded patient is necessary before broad implementation of this technique.

Abstract
BACKGROUND The aim of this study was to present existing publications, describing various diagnostic procedures as well as considering the evidence supporting them, to develop a recommendation for diagnosis. MATERIAL AND METHODS We reviewed relevant publications between 1966 and 2004 by a systemic literature search in MEDLINE, EMBASE, National Guideline Clearinghouse, Cochrane Library as well as a manual reference search. Keywords were cervical spine, cervical vertebrae, spinal, spinal cord, injury, trauma, fracture, dislocation, imaging, radiography, flexion, extension, fluoroscopy, computed tomography, computed scanning, and magnetic resonance imaging. The selected search results were then classified into levels of evidence. RESULTS From among a total of 10,000 publications, 137 relevant publications were stringently reviewed. The level of evidence is on the whole limited due to deficit data; therefore, only class II-III recommendations are possible. We developed an algorithm for the diagnostic approach to suspected trauma of the cervical spine. This clinical algorithm displays the complex diagnosis of cervical spine injury in a clear and logically structured process. CONCLUSIONS The diagnostic algorithm for cervical spine injury meets the presently required standards and maximizes care for the newly injured. The development, which can be followed using evidence-based medicine, is transparent and therefore aids the decision process when choosing an adequate diagnostic procedure.

Abstract
A retrospective case-control study was performed to determine if the addition of supine oblique radiographs to the routine cervical spine series results in the detection of patients with cervical spine injuries not identified with standard views alone. The cervical spine radiographs of 82 patients with known cervical spine injuries and 180 hospitalized patients without cervical spine injuries were collected. Radiographs of the two patient groups were randomly combined to form the study sample. The radiographs were reviewed independently by a board-certified radiologist and a board-certified emergency physician. During the first phase, each reviewer was provided with standard views of the cervical spine (lateral, anterior-posterior, open-mouth odontoid, and submental views). During the second phase, each reviewer was provided with the standard views and supine obliques. The reviewers were masked to all clinical information and previous radiologic interpretations. The results showed that in the first phase (standard views only), the two physicians had a sensitivity of 81% (95% confidence interval [CI] 74-87%) and a specificity of 93% (95% CI 90-96%). In the second phase (obliques included), the two physicians had a sensitivity of 76% (95% CI 69-83) and specificity of 90% (95% CI 87-93%). In a subset analysis of patients with posterior element (lamina, facet, and pedicle) fractures, the two physicians had a sensitivity of 88% (95% CI 78-95%) with standard radiographs and 86% (95% CI 76-94%) with the addition of oblique radiographs. In conclusion the addition of supine oblique radiographs to the standard trauma cervical spine series did not increase the readers' sensitivity for detecting patients with cervical spine injuries. Routinely including oblique radiographs in patients undergoing radiographic screening of the cervical spine is not warranted.

Abstract
Injuries of the cervical spine are relatively rare in children but are a distinct clinical entity compared with those found in adults. The unique biomechanics of the pediatric cervical spine lead to a different distribution of injuries and distinct radiographic features. Children younger than 9 years of age usually have upper cervical injuries, whereas older children, whose biomechanics more closely resemble those of adults, are prone to lower cervical injuries. Pediatric cervical injuries are more frequently ligamentous in nature, and children are also more prone to spinal cord injury without radiographic abnormality than adults are. Physical injuries are specific only to children. Radiographically benign findings, such as pseudosubluxation and synchondrosis, can be mistaken for traumatic injuries. External immobilization with a halo brace can be difficult and is associated with a high complication rate because of the thin calvaria in children. Surgical options have improved with the development of instrumentation specifically for children, but special considerations exist, such as the small size and growth potential of the pediatric spine.

Abstract
Ethical concerns have hindered any randomised control blinded studies on the imaging required to assess the cervical spine in an unconscious trauma patient. The issue has been contentious for many years and has resulted in burgeoning but inconclusive guidance. MRI and multislice CT technology have made rapid advances, but the literature is slower to catch up. Never the less there appears to be an emerging consensus for the multiply injured patient. The rapid primary clinical survey should be followed by lateral cervical spine, chest and pelvic radiographs. If a patient is unconscious then CT of the brain and at least down to C3 (and in the USA down to D1) has now become routine. The cranio-cervical scans should be a maximum of 2 mm thickness, and probably less, as undisplaced type II peg fractures, can be invisible even on 1 mm slices with reconstructions. If the lateral cervical radiograph and the CT scan are negative, then MRI is the investigation of choice to exclude instability. Patients with focal neurological signs, evidence of cord or disc injury, and patients whose surgery require pre-operative cord assessment should be imaged by MRI. It is also the investigation of choice for evaluating the complications and late sequela of trauma. If the patient is to have an MRI scan, the MR unit must be able to at least do a sagittal STIR sequence of the entire vertebral column to exclude non-contiguous injuries, which, since the advent of MRI, are now known to be relatively common. Any areas of oedema or collapse then require detailed CT evaluation. It is important that cases are handled by a suitably skilled multidisciplinary team, and avoid repeat imaging due to technical inadequacies. The aim of this review is to re-examine the role of cervical spine imaging in the context of new guidelines and technical advances in imaging techniques.

Abstract
BACKGROUND Screening methods for detecting cervical spine injury in obtunded ventilated patients continue to evolve. This study compared the use of plain radiography to computed tomographic (CT) scanning of cervical spines in the obtunded blunt trauma patient. The accuracy of plain radiography and CT scanning in detecting clinically significant cervical spine injury in the obtunded blunt trauma patient was evaluated. METHODS We conducted a prospective cohort study with a 3-year convenience sample. The study population consisted of a high-risk subpopulation of severely injured patients, intubated or with a Glasgow Coma Scale score < 9 at presentation. Patients were assessed with a three-view cervical spine series and a CT scan of their cervical spines from the skull base to T1. Independent-blinded review of plain radiographs and CT scans was performed by two radiologists. Sensitivity, specificity, and accuracy of plain films were compared with CT scanning. Sensitivity of CT scanning was compared with discharge diagnosis of cervical spine or cord injury. RESULTS One hundred two patients were eligible and underwent three-view plain radiography and CT scanning. Sensitivity, specificity, and accuracy of plain films compared with CT scanning were 39%, 98%, and 88%, respectively. CT scanning was 100% sensitive in detecting cervical spine injury. CONCLUSION CT scanning in conjunction with plain films enhances the number of cervical spine injuries seen radiographically. Application of a protocol of plain radiographs and CT scanning may be used to clear cervical spines in the obtunded trauma patient. Ongoing evaluation of this protocol is required.

Abstract
Improper handling of an unstable neck injury may result in iatrogenic neurologic injury. A review of published evidence on cervical management in the helmeted athlete with a suspected spinal injury is discussed. The approach to the neck-injured helmeted athlete and the algorithms for on-field and emergency department evaluations are reviewed. The characteristics of the fitted football helmet allow safe access for airway management, and helmets and shoulder pads should not be initially removed unless absolutely necessary. Prehospital and emergency personnel should be trained in the indications for removal and in proper helmet, shoulder pad, and facemask removal techniques. If required, both helmet and shoulder pads should be removed simultaneously. Radiographs with equipment in place may be inadequate, and the value of computed tomography and magnetic resonance imaging in these helmeted patients has been studied. If adequate films cannot be obtained with equipment in place, helmet and shoulder pads may need to be removed before radiographic clearance. A plan should be formulated to prepare for such unexpected clinical scenarios as cervical spine injuries, and skills should be practiced. Airway and cervical spine management in these helmeted athletes is an area of ongoing research.

Abstract
Cervical spine injury occurs in 5-10% of cases of blunt polytrauma. A missed or delayed diagnosis of cervical spine injury may be associated with permanent neurological sequelae. However, there is no consensus about the ideal evaluation and management of the potentially injured cervical spine and, despite the publication of numerous clinical guidelines, this issue remains controversial. In addition, many studies are limited in their application to the obtunded or unconscious trauma victim. This review will provide the clinician managing unconscious trauma victims with an assessment of the actual performance of clinical examination and imaging modalities in detecting cervical spine and isolated ligamentous injury, a review of existing guidelines in light of the available evidence, relative risk estimates and a proposed management scheme.

Abstract
Cervical spine trauma is a common reason for presentation to an emergency department. However, less than 5% of patients who have suffered possible neck injury actually have an injury requiring medical treatment. Nevertheless, the consequences, both for the patient and the doctor, of a missed injury are well recognized by emergency department medical staff. This results in the vast majority of these patients receiving some form of diagnostic imaging. We describe the development of an evidence-based imaging guideline for use in the patient who has suffered cervical spine trauma. The guideline aims to help clinicians determine, at the bedside, when it is appropriate to use imaging and which imaging modality should be used first. Correct utilization of the guideline should lead to a reduction in the number of imaging tests required to reach a diagnosis without adverse patient outcomes.

Abstract
BACKGROUND/PURPOSE Assessment of potential spine injuries is inconsistent and controversial. Subsequent morbidity includes prolonged immobilization and missed injuries. To address these issues, a multidisciplinary team was organized to design a cervical spine management/clearance pathway. The process, algorithm, and initial results are described. METHODS Team members consisted of pediatric surgeons, orthopedic surgeons, neurosurgeons, emergency room physicians, and trauma nurse practitioners. Nationwide standards, guidelines, and experiences across disciplines were reviewed, and a consensus pathway evolved for cervical spine clearance in children 8 years and younger. A short-term retrospective review (5 months) was performed to assess initial performance. Time required for clearance, number and type of imaging studies, and number of missed injuries were compared between a group of patients before (n = 71) and after (n = 56) the implementation of the pathway. RESULTS Strict guidelines for cervical spine immobilization and clearance criteria were defined. After implementation of this pathway, time required for cervical clearance in nonintubated children decreased (before, 12.3 +/- 1.5 v after, 7.5 +/- 0.9 hours; P =.014). A clear trend toward earlier clearance in intubated patients existed (before [n = 6], 40.0 +/- 16.8 v after [n = 6], 19.4 +/- 8.1 hours; P =.10); there need to be larger numbers to determine statistical significance. The 2 study groups were similar in age; mechanism of injury; Glasgow coma scale score; and number of plain x-rays, computed tomography scans, and magnetic resonance imaging studies obtained. Neither group had missed injuries. CONCLUSIONS standards for cervical spine immobilization, assessment, and clearance. Implementation of such guidelines decreased time for cervical spine clearance, and ongoing analysis of sensitivity is encouraging.

Abstract
DIAGNOSTIC STANDARDS There is insufficient evidence to support diagnostic standards. GUIDELINES In children who have experienced trauma and are alert, conversant, have no neurological deficit, no midline cervical tenderness, and no painful distracting injury, and are not intoxicated, cervical spine x-rays are not necessary to exclude cervical spine injury and are not recommended. In children who have experienced trauma and who are either not alert, nonconversant, or have neurological deficit, midline cervical tenderness, or painful distracting injury, or are intoxicated, it is recommended that anteroposterior and lateral cervical spine x-rays be obtained. OPTIONS In children younger than age 9 years who have experienced trauma, and who are nonconversant or have an altered mental status, a neurological deficit, neck pain, or a painful distracting injury, are intoxicated, or have unexplained hypotension, it is recommended that anteroposterior and lateral cervical spine x-rays be obtained. In children age 9 years or older who have experienced trauma, and who are nonconversant or have an altered mental status, a neurological deficit, neck pain, or a painful distracting injury, are intoxicated, or have unexplained hypotension, it is recommended that anteroposterior, lateral, and open-mouth cervical spine x-rays be obtained. Computed tomographic scanning with attention to the suspected level of neurological injury to exclude occult fractures or to evaluate regions not seen adequately on plain x-rays is recommended. Flexion/extension cervical x-rays or fluoroscopy may be considered to exclude gross ligamentous instability when there remains a suspicion of cervical spine instability after static x-rays are obtained. Magnetic resonance imaging of the cervical spine may be considered to exclude cord or nerve root compression, evaluate ligamentous integrity, or provide information regarding neurological prognosis. TREATMENT STANDARDS There is insufficient evidence to support treatment standards. GUIDELINES There is insufficient evidence to support treatment guidelines. OPTIONS Thoracic elevation or an occipital recess to prevent flexion of the head and neck when restrained supine on an otherwise flat backboard may allow for better neutral alignment and immobilization of the cervical spine in children younger than 8 years because of the relatively large head in these younger children and is recommended. Closed reduction and halo immobilization for injuries of the C2 synchondrosis between the body and odontoid is recommended in children younger than 7 years. Consideration of primary operative therapy is recommended for isolated ligamentous injuries of the cervical spine with associated deformity.

Abstract
OBJECTIVE The purpose of this study was to assess a cervical spine clearance protocol for blunt trauma patients using helical computed tomographic (CT) scan of the cervical spine (C-spine). METHODS A protocol using CT scan of the C-spine was implemented and the first 6 months of use reviewed. Patients requiring a CT scan of the head had the C-spine evaluated by lateral C-spine radiography and a helical CT scan. Patients without indication for CT scan of the head had the C-spine evaluated by three-view radiography (anteroposterior, lateral, and odontoid) with selective CT scan of the C-spine for imaging areas not well visualized or those with abnormalities identified by radiography or by clinical examination alone. RESULTS Three hundred twenty-four patients were admitted to the trauma center after blunt trauma during the first 6 months of protocol implementation. Head CT scans were obtained in 158 patients and lateral cervical spine radiography in conjunction with helical CT scanning evaluated the C-spine. The other 166 patients had the cervical spine cleared by three-view radiography series or by clinical examination alone. For patients in whom a head CT scan was not indicated, CT scanning was used only when plain radiographs failed to adequately visualize the entire C-spine. A total of 15 injuries (4.6% of the group) were detected. Seven injuries were suspected or detected by lateral plain radiographs and confirmed by CT scan. Six patients had an injury not detected by radiography but diagnosed by CT scan, and one patient had a false-positive radiograph. Of the remaining two injuries, one was diagnosed by magnetic resonance imaging and the other by CT scan outside of the protocol. Lateral plain radiographs alone failed to detect 46% (n = 6) of all injuries. CONCLUSION In our series, the selective use of helical CT scanning with plain radiography increased the accuracy with which cervical spine injury was detected from 54% to 100%. The protocol allowed for more rapid evaluation in many patients as well. We recommend that practice guidelines include the use of helical CT scan of the entire C-spine as the diagnostic procedure for those blunt trauma patients undergoing CT scanning of the head.

Abstract
OBJECTIVE The accurate evaluation of patients with multiple injuries is logistically complex and time sensitive, and must be cost-effective. We hypothesize that computed tomographic (CT) scan of the upper cervical spine (occiput to C3 [Co-C3]) would add little to the initial evaluation of patients with multiple injuries who have altered mental status. METHODS The study consisted of a prospective, unblinded, consecutive series. Patients met entry criteria if they had sustained a blunt mechanism of injury and had an altered mental status requiring CT scan of two or more body systems. All patients received CT scan of Co-C3 with 2-mm cuts and subsequent reconstructions as well as five-view cervical spine plain films. Cervical spine injury was defined as any radiographically identified fracture or subluxation that required treatment. Patients were excluded if they died or were cleared clinically before plain film series were obtained. CT scan of Co-C3 and cervical spine films were reviewed by two different attending radiologists. RESULTS Of the 2,690 consecutive admissions between December 1998 and November 1999, 1,356 patients met entry criteria. Seventy patients (5.2%) had a total of 95 injuries to the upper cervical spine. CT scan of Co-C3 identified 67 of 70 patients and plain films identified 38 of 70 patients with injuries to the upper cervical spine. Twelve patients (17%) had neurologic deficits attributable to Co-C3 injuries. Three patients had false-negative CT scans of Co-C3, and one patient was quadriplegic. There were 32 patients with false-negative plain films, including four patients with motor deficits (one with quadriplegia). Use of the guidelines developed by the Eastern Association for the Surgery of Trauma identified all patients with upper cervical spine injuries; to date, no patient in the study group was readmitted or has initiated a lawsuit for missed injury of the upper cervical spine. CONCLUSION CT scan of Co-C3 was superior to plain films in the early identification of upper cervical spine injury. Plain films failed to identify 45% of upper cervical spine injuries; four of these missed injuries resulted in motor deficits. Our study supports the practice guidelines developed by the Eastern Association for the Surgery of Trauma for clearance of the upper cervical spine in patients with altered mental status, as all patients with injuries were identified using these guidelines.

Abstract
Over the past 15 years there have been dramatic changes in the approach to imaging acute cervical spine trauma. This article addresses the current thoughts and controversies regarding the most appropriate techniques to evaluate the patient with cervical spine trauma, with an emphasis on the role of computed axial tomography (CT) and magnetic resonance imaging (MRI). The issue of clinical versus radiographic evaluation of low-risk patients is also discussed.

Abstract
BACKGROUND The potential for ligamentous injury of the cervical spine (C-spine) may mandate prolonged neck immobilization via a hard cervical collar in the blunt trauma victim (BTV) with altered sensorium. We investigated the incidence of ligamentous C-spine injuries, and whether applying (post hoc) the practice management guidelines from the Eastern Association for the Surgery of Trauma (three radiograph views plus computed tomographic scan of C1-C2) would have detected the injuries. METHODS The study was a 3-year retrospective review of BTVs admitted to the state's Primary Adult Resource Center for trauma from 1996 to 1998. Unreliable patients were defined as those with admission Glasgow Coma Scale score < 15. A rigorous algorithm to clear the C-spine was used. Pure ligamentous C-spine injury was defined as a C-spine having abnormal anatomic alignment, dislocation, subluxation, or listhesis, but without fracture. Demographics, diagnostic studies, presence of neurologic deficit, therapy, survival, and disposition were analyzed. RESULTS There were 14,577 BTVs with 614 (4.2%) patients having C-spine injury. There were 2,605 (18%) unreliable patients, with 143 (5.5%) of these having C-spine injury, 129 (90%) having fracture and 14 (10% of BTVs; 0.5% of unreliable patients) having no fracture. Of the 14 unreliable patients with pure ligamentous C-spine injury, 13 had initial diagnosis by supine cross-table lateral radiograph. The one exception had a normal three-view radiographic series, but atlanto-occipital dislocation was diagnosed by computed tomographic scan. Eight patients had upper level injury (C0-C4) and six were lower (C4-C7). Four patients died within 30 minutes after admission, 4 underwent cervical fusion, and 6 were treated with collar only. Five (50%) of the survivors had no apparent neurologic deficit attributed to the C-spine at admission. Nine patients remained institutionalized after discharge and one was discharged home. CONCLUSION Ligamentous injuries without fracture of the C-spine are rare. Application of the practice management guidelines developed by the Eastern Association for the Surgery of Trauma for identifying C-spine instability is effective and should facilitate early removal of the cervical collar in unreliable patients.

Abstract
A prospective study was performed over a 1-year period in patients who had sustained blunt trauma, mostly in motor vehicle accidents. All 73 patients (56 male and 17 female; age range, 2-94 years; mean age, 35.2 years) in the study had undergone intubation and ventilation at the trauma site (mean Glasgow Coma Score, 9.9 [range, 3-15]; mean Injury Severity Score, 30.4 [range, 8-75]) and subsequently underwent three-view radiography of the cervical spine and thin-section spiral computed tomography (CT) of the cervicothoracic junction. Spinal fractures were detected in 20 patients and involved the cervicothoracic junction region in 12 cases. In all 12 patients, the fractures were visualized at CT, whereas in seven of 12 patients, conventional radiography failed to demonstrate injuries (transverse process fracture of T1 [n = 1], pedicle and vertebral body fracture of C7 [n = 1], fractures of the first and second ribs [n = 5]). Thus, routine CT of the cervicothoracic junction in a highly select group of severely injured patients helped detect occult fracture in seven of 73 patients (10%); however, most of these fractures were not clinically significant. Larger studies involving a high-risk patient population are needed to confirm these findings.

Abstract
OBJECTIVE To evaluate the role of routine helical computed tomographic (CT) scan of the entire cervical spine in high-risk patients with multiple injuries. METHODS Prospective study of patients with severe blunt multiple injuries, requiring intensive care unit admission and CT scan of another body area besides the cervical spine. All patients were evaluated by means of standard cervical spine radiography. A complete cervical spine CT scan was performed during the same trip to the scanner in which other body areas were evaluated. The plain films and the CT scans were read by a radiologist in a blinded manner. RESULTS Fifty-eight patients fulfilled the criteria for inclusion in the study. The mean Glasgow Coma Scale score was 8.9 and the mean Injury Severity Score was 24.1. Twenty patients (34.4%) had cervical spine injuries (12 stable and 8 unstable injuries). Plain radiography missed eight injuries (including three unstable) and its sensitivity was 60%, specificity 100%, positive predictive value 100%, and negative predictive value 85.1%. The helical CT scan missed two spinal injuries (both stable) and its sensitivity was 90%, specificity was 100%, positive predictive value = 100%, negative predictive value = 95%. CONCLUSION There is a high incidence of cervical spine injuries in the severe, blunt, multiple-injury, unevaluable patients requiring intensive care unit admission. Plain radiography alone is not reliable in diagnosing many cervical spine injuries. Complete cervical spiral computed tomography is superior to plain radiography. It is suggested that in this selected group of patients, both plain radiography and spiral computed tomography should be performed.

Abstract
Phantom studies were performed to develop a technique for linear tomography of the craniocervical junction with a digital fluoroscopic angiographic C-arm unit. Section thicknesses were similar to those used at conventional tomography, and the radiation dose was lower. C-arm tomography was possible with a 6-second exposure and a 40 degrees arc. C-arm tomography is a practical method for decreasing patient turnaround time.

Abstract
The evaluation of spinal trauma and neck or back pain remains one of the most important and most common assessments in emergency medicine. This article provides an overview of an evidence based approach to this situation, and argues that appropriate use of imaging studies can reduce waste and better mitigate devastating outcomes to the patient.

Abstract
Polytrauma patients are at increased risk for occult cervical spine injuries. Those unable to provide clinical clues to injury either remain in hard collars until they are able to cooperate with the physical examination or are deemed "clear of cervical injury" if the emergency room screening radiographs are without obvious bony abnormality. Cervical immobilization for a lengthy period of time is not without morbidity. Missed ligamentous injuries can lead to cervical instability, which in turn can result in permanent neurologic sequelae. This article reviews the current methodologies to "clear the cervical spine" and highlights the inadequacies.

Abstract
A total of 582 consecutive patients with facial fractures were investigated prospectively for evidence of a concomitant cervical spine injury. Of them, 1.04% (6) were found to have a cervical spine injury, all having occurred in road traffic accidents. Only two of the injuries were diagnosable on standard, three-view, plain cervical spine radiographs. Four were diagnosable from computerized tomography scan, while the remaining two required stress views under radiographic screening for definitive diagnosis.

Abstract
STUDY OBJECTIVE To determine whether intracranial hemorrhage is a predictor of occult cervical-spine fracture. DESIGN A prospective, cross-sectional study. SETTING University-affiliated Level I trauma center. PARTICIPANTS Ninety-three blunt trauma victims with a Glasgow Coma Scale score of 12 or less. Exclusion criteria were incomplete radiographic evaluation caused by hemodynamic instability, death, or other reasons. INTERVENTIONS The study protocol required that all patients undergo a five-view cervical-spine trauma series, head computed tomography (CT), and upper cervical-spine CT. Cervical-spine radiographs and CT scans were read by two radiologists blinded to each other's interpretations. The results were compared with each patient's head CT diagnosis. Medical records were reviewed for demographic information and mechanism of injury. RESULTS Of the 93 patients, 54 had intracranial hemorrhage noted on CT scan; two of these patients had an upper cervical-spine fracture, but only one was an occult cervical-spine fracture. Thirty-nine patients had no intracranial hemorrhage; two patients had an upper cervical-spine fracture, but only one had an occult cervical-spine fracture. Fisher's exact test showed no significant difference between the rate of occult cervical-spine fracture between patients with and without hemorrhage. CONCLUSION Despite a high percentage of patients with traumatic intracranial hemorrhage, our study failed to demonstrate that intracranial hemorrhage is predictor of occult cervical-spine fracture.

Abstract
Radiographic evaluation of the cervical spine begins with anteroposterior, lateral, and odontoid views. Unless the junction of C7-T1 can be adequately visualized on the cross-table lateral view, a swimmer's view is often performed. After fractures and subluxations have been excluded with these nonstressed views, spinal stability may be evaluated with stressed view radiographs such as a flexion-extension series. However, there is currently no protocol for evaluating the distal spinal stability in patients in whom traditional flexion-extension radiographs fail to visualize the important distal C7-T1 juncture. The present case study describes a trauma patient suffering from neck pain in whom cervical spine instability was ruled out using a swimmer's flexion-extension technique. Further study of this technique as a supplement to the conventional flexion and extension views in the stressed assessment of the entire cervical spine is recommended.

Abstract
Undetected cervical-spine injuries are a nemesis to both trauma surgeons and emergency physicians. Radiographic protocols have been developed to avoid missing cervical-spine fractures but are not fail-safe. Three case reports of occult cervical fractures documented at autopsy in the face of normal cervical-spine radiographs and computerized tomography scans are presented.

Abstract
The usefulness of the anteroposterior (AP) radiograph of the cervical spine in contributing to the diagnosis of cervical spine injuries in the acute trauma patient was examined in a retrospective study. All cases of cervical spine fracture or dislocation seen at a level I trauma center over a 3-year period and at a rehabilitation center over a 10-year period were reviewed. The lateral radiograph, open-mouth odontoid radiograph, and AP radiograph of each case were sequentially examined by a neuroradiologist (blinded to the original diagnosis) to determine the contribution of each view in making a diagnosis of cervical spine injury. Results of these reviews showed that there were no cases of cervical spine injury evident on the AP view without an obvious corresponding abnormality on the lateral or open-mouth view. It was concluded that the AP view could be dropped from the initial screening radiographic study of the cervical spine in the trauma patient. Only an adequate lateral view and open-mouth odontoid view would then be necessary to initially evaluate the cervical spine in the trauma patient, and decisions to obtain further studies could be based safely on only the lateral and open-mouth views.
