Clearing the cervical spine of paediatric trauma patients

Cervical Collar Clearance in Obtunded Children Presenting Without a Known Traumatic Mechanism: Is Imaging Necessary?

BACKGROUND

Obtunded pediatric patients are often placed in cervical collars (c-collars) to protect their cervical spine (c-spine) while injury is being ruled out, even without a known traumatic injury. The goal of this study was to determine the necessity of c-collars in this population by determining the rate of c-spine injury among patients with suspected non-traumatic mechanisms of loss of consciousness.

METHODS

A single institution, ten-year retrospective chart review was conducted including all obtunded patients admitted to the Pediatric Intensive Care Unit without a known traumatic event. Patients were categorized into five groups based on etiology of obtundation: respiratory, cardiac, medical/metabolic, neurologic, and other. Comparisons were made between those placed in a c-collar and a control group who were not, using Wilcoxon rank sum test for continuous measures, and Chi-square or Fisher's exact test for categorical measures.

RESULTS

464 patients were included, of which 39 (8.41%) were placed in a c-collar. There was a significant difference in whether a patient was placed in a c-collar based on diagnosis category (p < 0.001). Those placed in a-c-collar were more likely to undergo imaging studies than the control group (p < 0.001). The overall incidence of c-spine injury in this patient population in our study was zero.

CONCLUSION

Cervical collar placement and radiographic evaluation is not necessary in obtunded pediatric patients who present without a known traumatic mechanism as the overall risk of injury is low. Consideration for collar placement should be given in cases when trauma cannot be definitively ruled out at initial evaluation.

How to interpret spinal imaging in paediatric trauma

Spinal injuries in children are fortunately rare; however, it is important that they are assessed and managed in a timely manner. A systematic approach to traumatic spinal injuries should be used, by following recent evidence and national protocols, in order to avoid misinterpretation and potentially, inappropriate discharge. The aim of this article is to highlight the concepts of spinal imaging in paediatric trauma with regards to indications, interpretation and limitations.

Safer Roads to School

Any and all advances made by medical science cannot solve the problem of road traffic injuries (RTIs) in school-going children, especially if the only concerned people are those of the medical fraternity. Children are a vulnerable part of the traveling population and thus have been persistent due to the callous nature of the citizens and policy makers toward road safety and injury prevention. In our multicultural and multilingual country, there is a need for multistakeholder initiative with a countrywide presence if we are to stem the rise of mortality and morbidity due to these accidents. The first question we need to ask is how to prevent road traffic accidents and improve the condition of our roads. Pediatric RTIs are eternal problem of industrial revolution with complications and effects that may affect individual and society with increase in the number of motorized communications. Dedicated capacity building is urgently need who should be able to provide the necessary care to the injured children at the road crash spot as well as should be informed where to take the injured child and whom to contact in the dedicated injury care center while transporting the victims of situations.

Traumatic Fracture of the Pediatric Cervical Spine: Etiology, Epidemiology, Concurrent Injuries, and an Analysis of Perioperative Outcomes Using the Kids' Inpatient Database

Background

The study aimed to characterize trends in incidence, etiology, fracture types, surgical procedures, complications, and concurrent injuries associated with traumatic pediatric cervical fracture using a nationwide database.

Methods

The Kids' Inpatient Database (KID) was queried. Trauma cases from 2003 to 2012 were identified, and cervical fracture patients were isolated. Demographics, etiologies, fracture levels, procedures, complications, and concurrent injuries were assessed. The t-tests elucidated significance for continuous variables, and χ² for categoric values. Logistic regressions identified predictors of spinal cord injury (SCI), surgery, any complication, and mortality. Level of significance was P < .05.

Results

A total of 11 196 fracture patients were isolated (age, 16.63 years; male, 65.7%; white, 65.4%; adolescent, 55.4%). Incidence significantly increased since 2003 (2003 vs 2012, 2.39% vs 3.12%, respectively), as did Charlson Comorbidity Index (CCI; 2003 vs 2012, 0.2012 vs 0.4408, respectively). Most common etiology was motor vehicle accidents (50.5%). Infants and children frequently fractured at C2 (closed: 43.1%, 32.9%); adolescents and young adults frequently fractured at C7 (closed: 23.9%, 26.5%). Upper cervical SCI was less common (5.8%) than lower cervical SCI (10.9%). Lower cervical unspecified-SCI, anterior cord syndrome, and other specified SCIs significantly decreased since 2003. Complications were common (acute respiratory distress syndrome, 7.8%; anemia, 6.7%; shock, 3.0%; and mortality, 4.2%), with bowel complications, cauda equina, anemia, and shock rates significantly increasing since 2003. Concurrent injuries were common (15.2% ribs; 14.4% skull; 7.1% pelvis) and have significantly increased since 2003. Predictors of SCI included sports injury and CCI. Predictors of surgery included falls, sports injuries, CCI, length of stay, and SCI. CCI, SCIs, and concurrent injuries were predictors of any complication and mortality, all (P < .001).

Conclusions

Since 2003, incidence, complications, concurrent injuries, and fusions have increased. CCI, SCI, falls, and sports injuries were significant predictors of surgical intervention. Decreased mortality and SCI rates may indicate improving emergency medical services and management guidelines.

Clinical Relevance

Clinicians should be aware of increased case complexity in the onset of added perioperative complications and concurrent injuries. Cervical fractures resultant of sports injuries should be scrutinized for concurrent SCIs.

Epidemiology of vertebral fractures in pediatric and adolescent patients

Spinal injuries in children and adolescents are rare injuries, but consequences for the growing skeleton can be devastating. Knowledge of accident causes, clinical symptoms and diagnostics should be part of every trauma department treating these patients. We retrospectively analyzed patients with radiographically proven vertebral fractures of the spine. After clinical examination and tentative diagnosis the fractures and injuries were proven with conventional X-ray, computed tomography (CT) scans or magnetic resonance imaging (MRI). The study included 890 fractures in 546 patients with an average age of 12.8±6.2 (6.6-19.4) years. Females had an average age of 13.7±6.3 (7.4-20.0) years, whereas males were on average 12.0 (6.0-18.0) years old. Fall from height (58%) was the main cause of accident and the most common region of fracture was the thoracolumbar spine with a shift towards the thoracic spine the more fractures occurred. Merely 3.7% of all patients required operative treatment. If a vertebral fracture is found in children and adolescents, it is highly recommended to exclude synchronous additional spine fractures in other levels; prevention should concentrate on fall and traffic accidents.

Delayed diagnosis of fractured anterior arch of the atlas in a young child

A 2-year-old girl fell off a bunk bed onto a parquet floor. She immediately reported neck pain and presented with muscle spasm and limited motion of the cervical spine (C-spine). Plain X-rays of the C-spine showed no osseous lesion. Owing to persisting pain and limited motion in the neck, MRI of the C-spine was obtained which revealed intact ligaments and cervical spinal cord, as well as soft tissue swelling in front of the anterior arch of the atlas. Subsequent CT of the C-spine confirmed a complete, undisplaced fracture of the anterior arch of the atlas (Gehweiler type I fracture). A Minerva cast was applied for 2 months, followed by a soft cervical collar. Persistent neck pain and limited range of motion of the neck after a fall may be indicative of atlas fracture that should be ruled out by CT.

The sensitivity and negative predictive value of a pediatric cervical spine clearance algorithm that minimizes computerized tomography

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.

Identification of Risk Factors for Cervical Spine Injury from Pediatric Trauma Registry

BACKGROUND

Cervical spine injuries are rare in children. Our goal is to establish guidelines for cervical spine clearance that are practical for our pediatric population, and, in the process, to reduce the risk of radiation exposure from unnecessary advanced imaging.

METHODS

We retrospectively reviewed the records from the registries of two pediatric trauma centers from the past 11 years (January 2002 to June 2013). Patients aged 1 month to 17 years, who had a CT scan of the cervical spine due to trauma indication for possible cervical spine injury, were evaluated.

RESULTS

Three risk factors were identified as being significant for the presence of a cervical spine injury. Patients who sustained a cervical spine injury were more likely to be male (p = 0.0261), were more severely injured with a higher injury severity score (ISS 16.39 ± 15.79 injured vs. 8.7 ± 9.4 uninjured), and presented with neck tenderness (p = 0.0001).

CONCLUSION

In our study, significant cervical spine injury is related to male gender, higher ISS and neck tenderness.

Implementation of pediatric cervical spine clearance guidelines at a combined trauma center: Twelve-month impact

BACKGROUND

Pediatric cervical spine clearance guidelines should reduce computed tomography (CT) usage in combined pediatric and adult trauma centers biased by adult CT clearance.

METHODS

Cervical spine clearance under age 15 years was compared 12 months before (128 patients) and after (105 patients) guideline implementation, emphasizing National Emergency X-Radiography Utilization Study (NEXUS) criteria when appropriate.

RESULTS

CT scans in patients clearable by NEXUS criteria decreased 23% (p = 0.01) and decreased by 16% in cases where radiography other than CT was indicated by guidelines (p = 0.01).

CONCLUSION

Guideline implementation can have an immediate effect in decreasing pediatric cervical spine CT usage and should improve across time.

Estimation of normal computed tomography measurements for the upper cervical spine in the pediatric age group

OBJECT

Upper cervical spine injuries in the pediatric age group have been recognized as extremely unstable from ligamentous disruption and as potentially lethal. Few measurement norms have been published for the pediatric upper cervical spine to help diagnose this pathological state. Instead, adult measurement techniques and results are usually applied inappropriately to children. The authors propose using high-resolution reconstructed CT scans to define a range of normal for a collection of selected upper cervical spine measurements in the pediatric age group.

METHODS

Sagittal and coronal reformatted images were obtained from thin axial CT scans obtained in 42 children (< 18 years) in a 2-month period. There were 25 boys and 17 girls. The mean age was 100.9 months (range 1-214 months). Six CT scans were obtained for nontrauma indications, and 36 were obtained as part of a trauma protocol and later cleared for cervical spine injury. Six straightforward and direct linear distances-basion-dental interval (BDI); atlantodental interval (ADI); posterior atlantodental interval (PADI); right and left lateral mass interval (LMI); right and left craniocervical interval (CCI); and prevertebral soft-tissue thickness at C-2-that minimized logistical and technical distortions were measured and recorded. Statistical analysis including interobserver agreement, age stratification, and sex differences was performed for each of the 6 measurements.

RESULTS

The mean ADI was 2.25 ± 0.24 mm (± SD), the mean PADI was 18.3 ± 0.07 mm, the mean BDI was 7.28 ± 0.10 mm, and the mean prevertebral soft tissue width at C-2 was 4.45 ± 0.43 mm. The overall mean CCI was 2.38 ± 0.44 mm, and the overall mean LMI was 2.91 ± 0.49 mm. Linear regression analysis demonstrated statistically significant age effects for PADI (increased 0.02 mm/month), BDI (decreased 0.02 mm/month), and CCI (decreased 0.01 mm/month). Similarly significant effects were found for sex; females demonstrated on average a smaller CCI by 0.26 mm and a smaller PADI by 2.12 mm. Moderate to high interrater reliability was demonstrated across all parameters.

CONCLUSIONS

Age-dependent and age-independent normal CT measurements of the upper cervical spine will help to differentiate physiological and pathological states in children. The BDI appears to change significantly with age but not sex; on the other hand, the LMI and ADI appear to be age-independent measures. This preliminary study suggests acceptable levels of interrater reliability, and further expanded study will aim to validate these measurements to produce a profile of normal upper cervical spine measurements in children.

Spinal clearance in unconscious children following traumatic brain injury

Spinal clearance in unconscious children following traumatic brain injury is an area of controversy. The risk of significant injury in this high-risk group needs to be balanced against that of prolonged spinal immobilization and all its implications. No national or international guideline exists to aid clinicians faced with such a scenario. This article reviews traumatic spinal injury in children looking at prevalence, risk factors, anatomical considerations, and radiological investigation. Spinal immobilization is discussed along with the use of appropriate and targeted radiological investigations to aid clearance.

Clearing the cervical spine in children

Increasing evidence from adult trauma patients has allowed the formation of some international consensus on clearance protocols. The evidence for paediatric trauma remains more fragmented, making the creation of definitive protocols difficult. Spinal injury in children differs from that in adults by injury distribution and prevalence, as well as anatomical and radiological differences. This complicates the process of clearance of the cervical spine in children. The evidence for clearance can be considered in terms of three groups of patients – the alert and asymptomatic child, the conscious child with high-risk criteria and the unconscious or obtunded child. This systematic review summarises the available evidence to clarify the current best practice for each group of patients.

The appropriate use of CT: quality improvement and clinical decision-making in pediatric emergency medicine

An increasing number of patients presenting to a shrinking number of hospital emergency departments has contributed to challenges to providing high-quality care, specifically care that is safe, efficient and effective. These challenges are magnified by trends in CT utilization with uncertain implications for care delivery. The utility of CT poses challenges to the pediatric emergency medicine physician to balance risk with potential benefit. We describe the process of evidence-based clinical decision-making to define the appropriate use of CT studies. Strategies for minimizing CT utilization in managing appendicitis, traumatic brain injury and cervical spine injuries are described. Clinical scores, clinical decision rules and evidence-based guidelines can assist the clinician in providing high-quality care through effective utilization of CT.

Pediatric cervical spine injuries: a comprehensive review

INTRODUCTION

Cervical spine injuries can be life-altering issues in the pediatric population. The aim of the present paper was to review this literature.

CONCLUSIONS

A comprehensive knowledge of the special anatomy and biomechanics of the spine of children is essential in diagnosis and treating issues related to spine injuries.

Infant trauma

Trauma forms the second largest cause of death in children under 1 year of age. Infants form a difficult cohort of patients; their range of development, differing physiology and inability to communicate or understand treatment makes them a challenge for any healthcare worker. Several factors compound this problem including a general lack of familiarity within non-specialised trauma services and the difficulty in studying infants as a cohort in academic research. This article aims to summarise the common problems encountered in dealing with infants in a trauma setting and specific differences in their management compared to other children or adults. Where possible it details current evidence most appropriate to the age group.

Application of imaging guidelines in patients with suspected cervical spine trauma: retrospective analysis and literature review

Safe and efficient clearance of cervical spine injury in blunt trauma patients has been a controversial topic among health professionals. The increased availability of CT scanners in major trauma centers seems to be a factor that has led to increased number of unnecessary cervical spine imaging using this imaging modality. The objective of this study was to investigate the applicability and efficacy of a pre-test clinical criterion in order to stratify post-blunt trauma victims based on their risk of sustaining cervical spine injury and in turn recommend an appropriate imaging modality accordingly. Goergen's criteria (Australas Radiol 48(3):287, 2004), a pre-investigation diagnostic algorithm was retrospectively applied to 106 blunt trauma victims who presented to a level 1 trauma center in Sydney, Australia, and had a CT scan of cervical spine as part of their initial management. Overall, nine (8.5%) of patients sustained a significant cervical spine injury. All nine patients would be classified as high-risk victims according to the algorithm investigated in this study, warranting CT scanning. No patients with low-risk injuries were demonstrated to have a significant cervical spine injury. There was a statistically significant greater proportion of acute cervical spine injuries detected in the high-risk group (p value = 0.0024). Hence, using Goergen's diagnostic algorithm could reduce the number of unnecessary cervical spine CT scans ordered, while not compromising the quality of care in post-blunt trauma victims.

Utility of a cervical spine clearance protocol after trauma in children between 0 and 3 years of age

OBJECT

Cervical spine clearance after trauma in children 0-3 years of age is deceptively difficult. Young children may not be able to communicate effectively, and severe injuries may require intubation and sedation. Currently, no published guidelines are available to aid in decision-making in these complex situations. The purpose of this study was to determine whether a safe and effective protocol-driven system could be developed for clearance of the cervical spine in noncommunicative children between 0 and 3 years of age.

METHODS

Children 0-3 years of age, including intubated patients, who were admitted after trauma activation at Primary Children's Medical Center in Salt Lake City or the Children's Hospital of New York from 2002 to 2006 were managed according to a cervical spine clearance protocol. Data were collected in a prospective fashion. Radiographic and clinical methods of clearing the cervical spine, as well as the type and management of injuries, were recorded.

RESULTS

A total of 2828 pediatric trauma activations required cervical spine clearance during the study period. Of these, 575 (20%) were children <or= 3 years of age who were admitted to the hospital. To facilitate clearing the cervical spine in these children, plain radiographs (100%), CT studies (14%), and MR images (10%) were obtained. Nineteen ligamentous injuries (3.3%) and 9 fractures/dislocations (1.5%) were detected, with 4 patients requiring operative stabilization (0.7%). No late injuries have been detected.

CONCLUSIONS

The protocol used has been effective in detecting cervical spine injuries in noncommunicative children after trauma. The combination of clinical information and radiographic studies is essential for safely clearing the cervical spine in these complex situations. Clearance of the cervical spine without CT or MR imaging studies is possible in the majority of cases, even in very young patients.

Cervical spine clearance in the nonalert, noncommunicative, or unreliable pediatric blunt trauma patient

Currently, there is no nationally recognized evidence-based guideline or protocol for cervical spine clearance in nonalert, noncommunicative, or unreliable pediatric blunt trauma patients. This descriptive survey study sought to identify current practices and elicit expert opinion data regarding pediatric cervical spine clearance in a specialized population of children in trauma centers in the United States. A 93-item electronic Pediatric Cervical Spine Clearance Survey was sent to 309 members of the Pediatric Special Interest Group of the National Society of Trauma Nurses. The main areas of interest in the survey included trauma verification, annual volume of pediatric trauma cases, and sequence and time frames of diagnostic testing for cervical spine clearance by age group. Additional areas of interest were perceived supports and barriers to meeting target time frames for diagnostic testing and outcomes to evaluate the impact of a cervical spine clearance guideline for pediatric blunt trauma. The results from 44 respondents demonstrate that trauma centers are using a variety of diagnostic testing sequences and time frames when clearing children for suspected cervical spine injury.

Developing a spinal clearance protocol for unconscious pediatric trauma patients

BACKGROUND

Spinal injury in pediatric trauma is associated with significant morbidity and mortality, but no current consensus exists on the safest and most effective method of clearance in the high-risk pediatric trauma patient.

METHODS

A retrospective analysis was performed on the records of 115 pediatric patients who had suffered major trauma and required admission to the pediatric intensive care unit of a United Kingdom level I trauma centre during a 7-year period from January 2000 to December 2006. The spinal imaging performed, and methods of clearance for each spinal region were obtained from analysis of written and electronic medical documentation.

RESULTS

In the cohort of 115 patients, there was a male predominance (63%) with motor vehicle accidents as the major mechanism of injury (63.5%). Ten patients (8.7%) were identified with spinal injuries, all of whom had sustained closed head injuries. Two of these patients had spinal cord injuries; one subsequently died. Spinal injury resulted in longer intubation times and intensive care stays, but no difference in new injury severity score or outcome. Clearance methods ranged from clinical examination to imaging with radiographs, computed tomography (CT), and dynamic screening. Magnetic resonance imaging was used as a secondary modality in two cases only, and in neither case was it used for clearance. CT demonstrated 100% specificity and sensitivity with positive and negative predictive values of 1 for all spinal regions. There were no cases of Spinal Cord Injury WithOut Radiologic Abnormality and no evidence of missed injuries.

CONCLUSIONS

There is a need for an evidence-based protocol for the clearance of the spine in the obtunded and high-risk pediatric trauma patient. High-resolution CT with sagittal and coronal reconstructions should be the basis for cervical spinal clearance, in combination with the interpretation of films by an expert radiologist. All spinal regions should be imaged, and clearance should be formally documented. The role of magnetic resonance imaging in routine clearance remains controversial. Multicenter prospective studies are needed to develop consensus for an evidenced-based protocol for clearance in this high-risk group.

`Clearing' the cervical spine in conscious trauma patients

This is a systematic review of published evidence regarding management of the cervical spine in conscious and co-operative trauma patients. We examine the literature in the following sections: clinical evaluation of the cervical spine; use of plain radiography; use of additional radiographic views; use of computed tomography; use of magnetic resonance imaging. Finally we consider the elderly and paediatric populations, particularly where there are significant differences compared to the general adult population. This paper also reviews the literature regarding non-medical assessment of the cervical spine. We conclude that there are well-validated decision rules available to guide the clinician, and that each imaging strategy has distinct advantages and disadvantages. Familiarity with these issues provides a sound basis for safe and effective decision-making.

Cervical spine injuries in children: attention to radiographic differences and stability compared to those in the adult patient

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

Detection of pediatric cervical spine injury

OBJECTIVE

In evaluating the pediatric cervical spine for injury, the use of adult protocols without sufficient sensitivity to pediatric injury patterns may lead to excessive radiation doses. Data on injury location and means of detection can inform pediatric-specific guideline development.

METHODS

We retrospectively identified pediatric patients with codes from the International Classification of Diseases, 9th Revision, for cervical spine injury treated between 1980 and 2000. Collected data included physical findings, radiographic means of detection, and location of injury. Sensitivity of plain x-rays and diagnostic yield from additional radiographic studies were calculated.

RESULTS

Of 239 patients, 190 had true injuries and adequate medical records; of these, 187 had adequate radiology records. Patients without radiographic abnormality were excluded. In 34 children younger than 8 years, National Emergency X-Radiography Utilization Study criteria missed two injuries (sensitivity, 94%), with 76% of injuries occurring from occiput-C2. In 158 children older than 8 years, National Emergency X-Radiography Utilization Study criteria identified all injured patients (sensitivity, 100%), with 25% of injuries occurring from occiput-C2. For children younger than 8 years, plain-film sensitivity was 75% and combination plain-film/occiput-C3 computed tomographic scan had a sensitivity of 94%, whereas combination plain-film and flexion-extension views had 81% sensitivity. In patients older than 8 years, the sensitivities were 93%, 97%, and 94%, respectively.

CONCLUSION

Younger children tend to have more rostral (occiput-C2) injuries compared with older children. The National Emergency X-Radiography Utilization Study protocol may have lower sensitivity in young children than in adults. Limited computed tomography from occiput-C3 may increase diagnostic yield appreciably in young children compared with flexion-extension views. Further prospective studies, especially of young children, are needed to develop reliable pediatric protocols.

CT versus plain radiographs for evaluation of c-spine injury in young children: do benefits outweigh risks?

BACKGROUND

Various reports support the use of cervical spine (c-spine) CT over conventional radiography in screening of c-spine injury. Interest now exists in diagnostic radiation-induced morbidity.

OBJECTIVE

To estimate excess relative risk for developing cancer from c-spine high-resolution CT radiation exposure.

MATERIALS AND METHODS

We conducted a retrospective review of children evaluated for c-spine injury using CT. The study population was divided into three age groups, 0-4 years (group 1), 5-8 years (group 2), and older than 8 years (group 3). Anthropomorphic 1-year-old and 5-year-old phantoms were used to measure radiation at the thyroid during radiography and CT. Excess relative risk for thyroid cancer was estimated using these measurements.

RESULTS

A total of 557 patients were evaluated with CT. The radiographic method most commonly used was head CT/c-spine CT in 363 (65%). Only 179 children (32%) had any type of prior radiography. The use of c-spine CT exposes the thyroid to 90-200 times more radiation than multiple conventional radiographs. The mean excess relative risk for thyroid cancer after CT was 2.0 for group 1 and 0.6 for group 2. There were no comparison data for group 3.

CONCLUSION

C-spine CT is associated with a significant exposure to ionizing radiation and increases excess relative risk for thyroid cancer in young children.

Anaesthesia for spinal surgery in children

Spinal surgery is performed in children of all age groups. Some of these children will have significant, other medical problems. For most, surgery will be performed in the prone position. Blood loss may be high for some types of surgery, and patients will benefit from use of a blood-sparing technique. Many patients will require spinal cord monitoring to assess cord function and to prevent neurological deficit.

Cervical spine clearance after trauma in children

OBJECT

Currently, no diagnostic or procedural standards exist for clearing the cervical spine in children after trauma. The establishment of protocols has been shown to reduce the time required to accomplish clearance and reduce the number of missed injuries. The purpose of this study was to determine if reeducation and initiation of a new protocol based on the National Emergency X-Radiography Utilization Study criteria could safely increase the number of pediatric cervical spines cleared by nonneurosurgical personnel.

METHODS

The authors collected and reviewed data regarding cervical spine clearance in children (age range 0-18 years) who presented to the emergency department at Primary Children's Medical Center in Salt Lake City, Utah, between 2001 and 2006 after sustaining significant trauma. Radiographic and clinical methods of clearing the cervical spine, as well as the type and management of injuries, were determined for two periods: Period I (January 2001-December 2003) and Period II (January 2004-February 2006). Between 2001 and 2003, 95% of 936 cervical spines were cleared by the neurosurgical service. Twenty-one ligamentous injuries (2.2%) and 12 fracture/dislocations (1.3%) were detected, and five patients (0.5%) required operative stabilization. Since January 2004, 585 (62.4%) of 937 cervical spines have been cleared by nonneurosurgical personnel. Twelve ligamentous injuries (1.3%) and 14 fracture/dislocations (1.5%) were identified, and four patients (0.4%) required operative stabilization. No late injuries were detected in either time period.

CONCLUSIONS

The protocol outlined in the paper has been effective in detecting cervical spine injuries in children after trauma and has increased the number of cervical spines cleared by nonneurosurgical personnel by nearly 60%. Reeducation with the establishment of protocols can safely facilitate clearance of the cervical spine after trauma by nonneurosurgical personnel.

Cervical spine clearance after trauma in children

Object

Currently, no diagnostic or procedural standards exist for clearing the cervical spine in children after trauma. The purpose of this study was to determine if reeducation of nonneurosurgical personnel and initiation of a new protocol based on the National Emergency X-Radiography Utilization Study criteria could safely increase the number of pediatric cervical spines cleared of suspected injury without a neurosurgical consultation.

Methods

Data regarding cervical spine clearance in children (ages 0–18 years) after trauma protocol activation at Primary Children's Medical Center between 2001 and 2005 were collected and reviewed. Radiographic and clinical methods of clearing the cervical spine as well as the type and management of injuries were determined for two time frames: Period I (January 2001–December 2003) and Period II (January 2004–July 2005).

Between 2001 and 2003, 95% of 936 cervical spines were cleared of suspected injury by the neurosurgical service. Twenty-one ligamentous injuries (2.2%) and 12 fracture–dislocations (1.3%) were detected, with five patients requiring surgical stabilization (0.5%). Between January 2004 and July 2005, 507 (68%) of 746 cervical spines were cleared by nonneurosurgical personnel. Six ligamentous injuries (0.8%) and 10 fracture–dislocations (1.3%) were identified, with three patients (0.4%) requiring surgical stabilization. No late injuries were detected in either period.

Conclusions

The protocol used has been effective in enabling detection of cervical spine injuries in children after trauma, with the new protocol increasing by more than 60% the number of cervical spines cleared by nonneurosurgical personnel. Reeducation with establishment of the new protocols can safely facilitate clearance of the cervical spine by nonneurosurgical personnel after trauma.

Physiologic anterior subluxation: Case report of occurrence at C5 to C6 and C6 to C7 spinal levels

Physiologic anterior subluxation is a phenomenon that is common to the upper pediatric cervical spine and characterized by the normal forward displacement of one cervical vertebra relative to the subjacent one. Physiologic anterior subluxation can be seen in children in the setting of trauma, when it must be distinguished from pathologic subluxation. Physiologic anterior subluxation has not been reported at lower cervical spinal levels (C 5 to C 6 or C 6 to C 7 ). This is a report of physiologic anterior subluxation at C 5 to C 6 and C 6 to C 7 spinal levels distinguished from pathologic subluxation in a 9-year-old child evaluated in the acute setting after cervical spine injury.
