Management of pediatric cervical spine and spinal cord injuries

Pediatric Spinal Cord Injury: A Review

A spinal cord injury (SCI) can be a devastating condition in children, with profound implications for their overall health and quality of life. In this review, we aim to provide a concise overview of the key aspects associated with SCIs in the pediatric population. Firstly, we discuss the etiology and epidemiology of SCIs in children, highlighting the diverse range of causes. We explore the unique anatomical and physiological characteristics of the developing spinal cord that contribute to the specific challenges faced by pediatric patients. Next, we delve into the clinical presentation and diagnostic methods, emphasizing the importance of prompt and accurate diagnosis to facilitate appropriate interventions. Furthermore, we approach the multidisciplinary management of pediatric SCIs, encompassing acute medical care, surgical interventions, and ongoing supportive therapies. Finally, we explore emerging research as well as innovative therapies in the field, and we emphasize the need for continued advancements in understanding and treating SCIs in children to improve their functional independence and overall quality of life.

Developing a Guideline for Neurotrauma in Nigeria

BACKGROUND

The Nigerian Academy of Neurological Surgeons in 2019 resolved to standardize the practice of neurosurgery in Nigeria. It set up committees to standardize the various aspects of neurosurgery, such as neurotrauma, pediatrics, functional, vascular, skull base, brain tumor, and spine. The Committee on Neurotrauma convened and resolved to study most of the available protocols and guidelines in use in different parts of the world.

OBJECTIVE

To formulate a standard protocol for the practice of neurotrauma care within the Nigerian locality.

METHODS

The Committee split its membership into 3 subcommittees to cover the various aspects of the Neurotrauma Guidelines, such as neurotrauma curriculum, standard neurotrauma management protocols, and neurotrauma registry. Each subcommittee was to research on available models and formulate a draft for Nigerian neurotrauma.

RESULTS

All the 3 subcommittees had their reports ready on schedule. Each concurred that neurotrauma is a major public health challenge in Nigeria. They produced 3 different drafts on the 3 thematic areas of the project. The subcommittees are: 1. Subcommittee on Fellowship, Training and Research Curriculum; 2. Subcommittee on Standard Protocols and Management Guidelines; and 3. Subcommittee of the Nigerian Neurotrauma Registry.

CONCLUSION

The committee concluded that a formal protocol for neurotrauma care is long overdue in Nigeria for the standardization of all aspects of neurotrauma. It then recommended the adoption of these guidelines by all institutions offering services in Nigeria using the management protocols, opening a registry, and mounting researches on the various aspects of neurotrauma.

Is spinal computed tomography necessary in pediatric trauma patients?

BACKGROUND

To investigate the prevalence of findings of spinal injury on computed tomography (CT) images of pediatric trauma patients and to define indicators for the possible presence of spinal injuries.

METHODS

Spinal CT for pediatric trauma patients (age ≤ 12 years) over a 2-year period was retrospectively evaluated for the presence of findings suggestive of spinal injury.

RESULTS

Of the 773 patients reviewed, 19 (2.4%) showed traumatic spinal lesions on their spinal CT images. These patients were significantly older than those without spinal lesions (mean age 7.9 ± 3.3 years vs 6.1 ± 3.3 years; P = 0.02). The prevalence of spinal trauma was significantly lower in patients aged 0-8 years than in those aged 9-12 years (P = 0.025). Spinal injury was significantly higher in female patients (P = 0.014). Most of the spinal injuries were located at the lumbar and sacral vertebral levels, and most did not cause neurological complications or require surgical treatment. Important indicators of the possible presence of spinal injuries were pain, tenderness, or ecchymosis over the spine, a low Glasgow Coma Scale score (≤12), head injury (for cervical injuries), or intrathoracic injuries and pelvic fractures (for lumbar and sacral injuries).

CONCLUSIONS

Most spinal CT examinations for the diagnosis of spinal injuries in children did not show positive findings. Thus, many children were exposed to an unnecessary high dose of radiation. New clinical evaluation criteria and indicators should be defined to diagnose spinal injuries and avoid unnecessary radiological examinations.

Determinants of Pediatric EMS Utilization in Children with High-Acuity Conditions

BACKGROUND

Underutilization of emergency medical services (EMS) for children with high-acuity conditions is poorly understood. Our objective was to identify differences in demographic factors and describe caregivers' knowledge, beliefs, and attitudes regarding EMS utilization for children with high-acuity conditions.

DESIGN/METHODS

This was a mixed-methods study of children with high acuity conditions, defined as requiring immediate medical or surgical intervention and intensive care admission, over a one year period. Demographic data were collected through a retrospective chart review. Qualitative analysis of semi-structured interviews from a purposive sample of caregivers was conducted until thematic saturation was achieved.

RESULTS

Three hundred seventy-four charts were reviewed; 19 caregivers were interviewed (17 in-person, 2 via telephone). The 232 (62%) children not arriving by EMS tended to be younger (1.58 years vs. 2.31 years, p = 0.02), privately insured (30% vs. 19%, p = 0.04), and lived further from the hospital (16.80 miles vs. 12.45 miles, p = 0.001). Patient gender, ethnicity, comorbidities and caregiver language were not associated with EMS underutilization. Immediate invasive medical interventions were more often required for EMS utilizers (85% vs. 60%, p < 0.001). EMS utilizers were more likely to require intubation (78% vs. 47%, p < 0.001) and cardiopulmonary resuscitation (CPR) (26% vs. 2%, p < 0.001), and had shorter hospital stays (4.70 vs. 8.16 days; p-value < 0.001). Three principal themes determined EMS utilization: expectations, knowledge, and perceived barriers. Three principal themes determined EMS utilization: expectations, knowledge, and perceived barriers. Caretakers expected EMS would provide timely, safe transportation that expedited medical care and emotional support. Medical knowledge and prior experience with EMS influenced decision-making about arrival mode. Timeliness, cost, socioeconomic and demographic characteristics, loss of autonomy, and the logistics of EMS activation and transport were the most commonly reported barriers.

CONCLUSIONS

Young age, private insurance status, and greater distance from the hospital were associated with EMS underutilization. Understanding caregiver expectations, knowledge, and perceived barriers may have important implications for the use of EMS for children. These findings reveal opportunities for improved public education on EMS systems to enhance appropriate EMS utilization for children with high acuity conditions.

Craniovertebral junction injuries in children. A Review

The craniovertebral junction (CVJ) is the most complex and dynamic region of the cervical spine. The wide range of movements possible at this region makes it vulnerable to injury and instability. The special anatomical features make children more prone to injuries of CVJ than adults where lower cervical spine is involved more frequently. The classical clinical manifestation in CVJ injury patients are pyramidal signs including weakness and spasticity, stigmata of CVJ anomalies (short neck, low hair line, facial or hand asymmetry, high arched palate, ), torticolis and neck movement restriction. The history of transient loss of consciousness or sudden neurological deterioration following minor trauma may be elicited. Most authors advocate conservative management (in form of immobilization) of CVJ injuries in children as is true in adults. Halo vest provides superior immobilization in upper cervical and CVJ injuries and can be used in a child as young as 1 year of age with minimal difficulty. Early surgical intervention, i.e. within 2 weeks of injury include is indicated in injuries that cannot be reduced and stabilized by external means, partial spinal cord injury with progressive neurological deficit and in children with extradural hematoma.

Successful delayed non-operative management of C2 neurosynchondrosis fractures in a pediatric patient: a case report and review of management strategies and considerations for treatment

Upper cervical synchondrosis fractures are the most common types of cervical fractures in the pediatric population less than 7 years of age (Blauth et al (Eur Spine J 5:63-70, 1996); Connolly et al (Pediatr Radiol 25(Suppl1):S129-133, 1995); Mandabach et al (Pediatr Neurosurg 19(5):225-232, 1993); Schippers et al (Acta Neurochir 138:524-530, 1990)) The vast majority occur through the dentocentral or basilar synchondrosis. We present the second reported case in recent literature of a unilateral neurosynchondrosis fracture. The patient, a 4-year-old male, was initially managed conservatively with a rigid cervical collar for a period of 3 months. Despite multiple counseling sessions with family, the patient remained poorly compliant with cervical immobilization. After 3 months, imaging demonstrated partial fusion with persistent anterolisthesis of C2 on C3. The decision was made to place the child in external halo fixation as an attempt to achieve fusion prior to committing to internal surgical fixation and the associated sequelae. Immobilization with a hard cervical collar is often first line treatment. In the case of failed fusion, debate exists regarding surgical fixation in children. Occipito-atlanto-axial fusion leads to permanent loss of a significant degree of flexion, extension, and rotatory movement. The pediatric population has a strong propensity to fuse; however, compliance is often a barrier to conservative treatment due to age-related behavioral practices. We demonstrate that even with initial failed fusion and progression of deformity while in a cervical collar, conservative management with external halo fixation can potentially obviate the need for internal fixation.

Management of traumatic spinal injuries in children and young adults

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.

Cervical spine imaging in hospitalized children with traumatic brain injury

OBJECTIVES

The purposes of this study, in children with traumatic brain injury (TBI), to describe cervical spine imaging practice, to assess for recent changes in imaging practice, and to determine whether cervical spine computed tomography (CT) is being used in children at low risk for cervical spine injury.

METHODS

The setting was children's hospitals participating in the Pediatric Health Information System database, from January 2001 to June 2011. Participants were children (younger than 18 y) with TBI who were evaluated in the emergency department, admitted to the hospital, and received a head CT scan on the day of admission. The primary outcome measures were cervical spine imaging studies. This study was exempted from institutional review board assessment.

RESULTS

A total of 30,112 children met study criteria. Overall, 52% (15,687/30,112) received cervical spine imaging. The use of cervical spine radiographs alone decreased between 2001 (47%) and 2011 (23%), with an annual decrease of 2.2% (95% confidence interval [CI], 1.1%-3.3%), and was largely replaced by an increased use of CT, with or without radiographs (8.6% in 2001 and 19.5% in 2011, with an annual increase of 0.9%; 95% CI, 0.1%-1.8%). A total of 2545 children received cervical spine CT despite being discharged alive from the hospital in less than 72 hours, and 1655 of those had a low-risk mechanism of injury.

CONCLUSIONS

The adoption of CT clearance of the cervical spine in adults seems to have influenced the care of children with TBI, despite concerns about radiation exposure.

An analysis of cervical spine magnetic resonance imaging findings after normal computed tomographic imaging findings in pediatric trauma patients: ten-year experience of a level I pediatric trauma center

BACKGROUND

A variety of radiologic screening protocols exist for evaluation of pediatric trauma patients with potential cervical spine (c-spine) injuries. The purpose of this study was to describe findings on c-spine magnetic resonance imaging (MRI) after previously normal c-spine computed tomographic (CT) scan findings at a Level 1 trauma center.

METHODS

A retrospective chart review of trauma patients evaluated at Rady Children's Hospital, San Diego, between January 2000 and February 2010 was conducted. Trauma patients who were younger than 18 years, placed in c-spine precautions, had a normal c-spine CT scan, who subsequently had a c-spine MRI were included. The sample was subdivided into patients who underwent CT scans between January 1, 2000 to July 31, 2005 (early group), and August 1, 2005 to February 28, 2010 (late group), to compare results between different CT scan resolutions.

RESULTS

A total of 173 patients met inclusion criteria. With 100% of patients demonstrating normal c-spine CT scan findings, 83% of c-spine MRI findings were also negative (p < 0.001). Thirty patients (17%) demonstrated significant abnormalities on MRI. Of the 30, 5 (2.9%) required operative c-spine stabilization. Eighty-five patients underwent CT scan in the early group, and 88 in the late group. All 5 patients with unstable injuries not discovered on CT scan were from the early group, compared with none in the late group (p = 0.027).

CONCLUSION

Our results suggest that high-resolution CT scan with sagittal and coronal reconstructions may be comparable with MRI for the detection of unstable c-spine injuries in pediatric trauma patients. Although minimizing CT scan radiation exposure remains essential, high-resolution c-spine CT scan may allow for earlier c-spine clearance with reduction of associated hard collar comorbidities in centers where MRI is not available or in situations where the patient's clinical stability precludes obtaining MRI.

LEVEL OF EVIDENCE

Diagnostic study, level III.

Developmental biomechanics of neck musculature

Neck mechanics is central to head injury prevention since it is the musculoskeletal neck, which dictates the position and movement of the head. In the US, traumatic injury is the leading cause of death for children; however prevention is hampered by the lack of data concerning the mechanics of the immature head-and-neck. Thus, the objective of this study was to quantify neck muscle strength and endurance across the maturation spectrum and correlate these with head-and-neck anthropometry. A factorial study was performed on 91 human subjects measuring head-and-neck anthropometry and neck strength and endurance in three bending directions (flexion, extension, and lateral) as a function of age (6-23 years). Using a custom device, neck maximum voluntary contraction (MVC) force was measured in triplicate. Next, neck muscle endurance (sustained effort) was measured as the subjects' ability to maintain 70% of peak force over 30s. Linear regression of peak force and endurance as a function of age revealed each direction to significantly (p<0.0001) increase with age. The MVC force, averaged across all directions and normalized to the adult values, exhibits the following maturation curve: %MVC Force=-0.0879(age)(2)+6.018(age)+8.120. Neck muscle strength, similar between young males and females, becomes disparate in adolescence and adulthood with males exhibiting greater strength. Bending direction differences were also found with extension strength being the greatest regardless of age and sex. Furthermore, neck circumference appears predictive of neck strength and endurance in children. Together, these relationships may facilitate improved design of injury prevention interventions.

The pediatric cervical spine instability study. A pilot study assessing the prognostic value of four imaging modalities in clearing the cervical spine for children with severe traumatic injuries

PURPOSE

Cervical spine clearance in severely injured children after trauma is often difficult because of unique injury patterns, concerns about radiation exposure to growing tissue, and unfamiliarity with unstable cervical injuries. We prospectively assessed the utility of four radiographic modalities to clear the cervical spine in children after severe trauma.

METHODS

Twenty-four comatose, intubated children with severe traumatic injuries underwent radiographic evaluation to clear the cervical spine. Each patient had plain radiographs, flexion-extension radiographs under fluoroscopy, computed tomography (CT), and magnetic resonance (MR) imaging within 10 days of admission. Patients underwent cervical spine flexion-extension radiographs 2-3 months after trauma to detect late instability. Sensitivity and specificity for each radiographic modality was determined.

RESULTS

Plain cervical spine radiographs demonstrated sensitivity of 100% and specificity of 95%; flexion-extension radiographs had “indeterminate” sensitivity and specificity of 100%. For CT, sensitivity was 100% and specificity was 95%, and for MR imaging, sensitivity was 100% and specificity was 74%.

CONCLUSIONS

There was a low prevalence of cervical instability in this high-risk group. Plain radiographs, flexion-extension radiographs, and CT all had high sensitivities and specificities. MR imaging had a high false-positive rate, making it sensitive but not specific. The data support using either CT or plain radiographs as the initial cervical spine screening study, but CT is recommended because of its superior ability to detect critical injuries. To definitively rule out ligamentous instability after a negative screening CT scan or cervical spine X-ray, these data support using flexion-extension X-rays with fluoroscopy and not MR imaging.

Advances in the management of spinal cord and spinal column injuries

Spinal cord injury (SCI) is a significant public problem, with recent data suggesting that over 1 million people in the U.S.A. alone are affected by paralysis resulting from SCI. Recent advances in prehospital care have improved survival as well as reduced incidence and severity of SCI following spine trauma. Furthermore, increased understanding of the secondary mechanisms of injury following SCI has provided improvements in critical care and acute management in patients suffering from SCI, thus limiting morbidity following injury. In addition, improved technology and biomechanical understanding of the mechanisms of spine trauma have allowed further advances in available techniques for spinal decompression and stabilization. In this chapter we review the most recent data and salient literature regarding SCI and address current controversies, including the use of pharmacological adjuncts in the setting of acute SCI. We will also attempt to provide a reader with basic understanding of the classifications of SCI and spinal column injury. Finally, we review advances in spinal column stabilization including improvements in instrumented fusion and minimally invasive surgery.

Methodology of systematic reviews and recommendations

Although research in the field of spinal cord injury (SCI) is a relatively new endeavor, a remarkable number of papers focused on this subspecialty have been published in a broad variety of journals over the last two decades. A multidisciplinary group of experts, including clinical epidemiologists, neurosurgical and orthopedic spine surgeons, basic scientists, rehabilitation specialists, intensivists, and allied health professionals (nursing and physical therapy) was assembled through the Spinal Cord Injury Solutions Network to summarize the existing literature focusing on 12 key topics related to acute traumatic SCI, which have not been recently reviewed. The objective was to develop evidence-based recommendations to help translate current science into clinical practice and to identify new directions for research. For each topic one to three specific questions were formulated by consensus through the expert panel. A systematic review of the literature was performed to determine the current evidence for the specific questions. A primary literature search was performed using MEDLINE, CINAHL, EMBASE, and Cochrane databases. A secondary search strategy incorporated additional articles referenced in significant publications (i.e., meta-analysis, systematic and nonsystematic review articles). Two reviewers independently reviewed the titles and abstracts yielded by this comprehensive search and subsequently selected articles based on the predetermined inclusion and inclusion criteria. Data were extracted for population into evidentiary tables. Selected articles were rated for level of evidence and methodological quality, information that was also included in evidentiary tables. Disagreements were resolved by a third reviewer or consensus-based discussion. Based on the evidence compiled, answers to the targeted questions were formulated and recommendations generated by consensus-based discussion and anonymized voting using Delphi methodology. A level of consensus of 80% or higher was considered to represent strong agreement.

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.

Epidemiology and Management of Injuries to the Spinal Cord and Column in Pediatric Multiple-Trauma Patients

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.

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.

Neural space and biomechanical integrity of the developing cervical spine in compression

STUDY DESIGN

A factorial study design was used to examine the biomechanical and neuroprotective integrity of the cervical spine throughout maturation using a postmortem baboon model.

OBJECTIVE

To investigate changes with spinal development that affect the neuroprotective ability of the cervical spine in compressive loading.

SUMMARY OF BACKGROUND DATA

Child spinal cord injuries claim and debilitate thousands of children in the United States each year. Many of these injuries are diagnostically and mechanistically difficult to classify, treat, and prevent. Biomechanical studies on maturing spinal tissues have identified decreased stiffness and tolerance characteristics for children compared with adults. Unfortunately, while neurologic deficit typically dictates functional outcome, no previous studies have examined the neuroprotective role of the pediatric cervical spine.

METHODS

Twenty-two postmortem baboon cervical spines across the developmental age spectrum were tested. Two functional spinal unit segments (Oc-C2, C3-C5, and C6-T1) were instrumented with transducers to measure dynamic changes in the spinal canal. These tissues were compressed to 70% strain dynamically, and the resultant mechanics and spinal canal occlusions were recorded.

RESULTS

Classic injury patterns were observed in all of the specimens tested. The compressive mechanics exhibited a significant age relationship (P < 0.0001). Furthermore, while the peak-percent spinal canal occlusion was not age dependent, the percent occlusion just before failure did demonstrate a significant decrease with advancing age (P = 0.0001).

CONCLUSIONS

The neuroprotective ability of the cervical spine preceding failure appears to be age dependent, where the young spine can produce greater spinal canal occlusions without failure than its adult counterpart. The overall percent of the spinal canal occluded during a compression injury was not age dependent; however, these data reveal the neuroprotective ability of the child spine to be more sensitive as an injury predictor than the biomechanical fracture data.

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.

[Pediatric acute spinal cord injury]

INTRODUCTION

Pediatric acute spinal cord injury is rare but is often associated with significant disability and prolonged stay in the intensive care unit (ICU).

OBJECTIVES

The main objective of this study was to determine the epidemiology, initial clinical abnormalities, diagnostic studies, treatment and outcome of acute spinal cord injuries in a tertiary level pediatric hospital. A second objective was to analyze whether early tracheostomy allows earlier discharge of these patients.

PATIENTS AND METHODS

A retrospective analysis of patients with acute spinal cord injuries admitted to our pediatric ICU since 1992 was performed.

RESULTS

We included 16 patients in the study, 12 of whom were boys (75 %). The patients were aged from birth to 19 years on admission to the ICU. The length of stay in the ICU was between 12 hours and 6 years. The cause of the lesion was birth trauma in four patients; one died and the remaining three live at home under mechanical ventilation. Traumatic injuries occurred in seven patients, two of whom died; a further two live in a long-term care facility and the remaining three live at home. Vascular spinal malformation occurred in two patients, and the three remaining injuries occurred during the acute postoperative period following spinal surgery. Of the 16 children, 56.2 % were tracheostomized and 83 % of the survivors live at home.

CONCLUSIONS

Early tracheostomy, the availability of invasive ventilation for home use and parent education permit earlier discharge of these patients and allow more of them to live at home.

Two Cases of Odontoid Fracture in Preschool Children

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

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.

Temporary anterior cervical plating in a child with traumatic cervical ligamentous instability

Application of anterior cervical plates in children is problematic because of the growing spine, and thus has been reported only rarely in the medical literature. In this case report, a 7-year-old with traumatic C(2-3) and C(3-4) ligamentous instability was treated surgically by limited-duration anterior cervical plating. The plate was removed in a second operation, as the osseous union occurred 1 year after the primary operation. Limited-duration anterior cervical plating is an alternative for stabilization operations of the growing cervical spine in children.

Spinal injuries in children

BACKGROUND/PURPOSE

Traumatic spinal injury (TSI) is an uncommon source of morbidity and mortality in children. The aim of this study was to describe childhood TSI in a single level 1 urban pediatric trauma center.

METHODS

The authors retrospectively analyzed all children younger than 14 years with TSI, treated at a level I pediatric trauma center between 1991 and 2002 (n = 406, 4% total registry). All children were stratified according to demographics, mechanisms, type and level of injury, radiologic evaluations, associated injuries, and mortality.

RESULTS

The mean age was 9.48 +/- 3.81 years. The most common overall mechanism of injury was motor vehicle crash (MVC; 29%) and ranked highest for infants. Falls ranked highest for ages 2 to 9 years. Sports ranked highest in the 10 to 14 year age group. Paravertebral soft tissue injuries were 68%. The most common injury level was the high cervical spine (O-C4). The incidence of spinal cord injury without radiologic abnormality (SCIWORA) was 6%. Traumatic brain injury (37%) was the most common associated injury. Overall mortality rate was 4% in this urban catchment.

CONCLUSIONS

TSI in children requires a different preventive and therapeutic logarithm compared with that of adults. The potential devastating nature of TSI warrants that the health care team always maintains a high index of suspicion for injury. Future prospective studies are needed to further elucidate injury patterns.
