Pediatric spinal injury in the US: epidemiology and disparities

Child Opportunity Index Predicts Outcomes in Pediatric Spine Trauma: A Novel Application of Social Determinants of Health

Objectives: Social factors play a crucial role in health outcomes for pediatric patients, yet in the neurosurgery pediatric literature, these factors are rarely reported. To develop a deeper understanding of pediatric spine trauma outcomes, we investigate demographic and social factors measured by the Child Opportunity Index (COI) and Social Deprivation Index (SDI). We hypothesize that social factors predict clinical presentation, injury severity, and clinical outcomes. Methods: We conducted a retrospective cohort study of pediatric patients treated for spinal trauma at a Level 1 trauma center in Sacramento, California. We collected patient clinical data such as mechanisms of injury (MOIs), length of stay (LOS), treatment type, hospital disposition, polytrauma incidence, and follow-up attendance. Each patient's social environment was characterized using COI and SDI metrics. Statistical comparisons were performed to assess associations between social factors and clinical outcomes. Results: Patients with worse childhood opportunity (lower COI and higher SDI) were more likely to be insured through Medi-Cal, identify as Hispanic, and experience violent MOI. Female patients were more likely to sustain polytrauma and had a higher likelihood of requiring surgical intervention. Additionally, patients from underserved communities demonstrated longer hospital stays and poorer follow-up adherence, with COI and SDI scores correlating with these disparities. Conclusion: Social disparities are associated with worse outcomes in pediatric spine trauma. We found COI and SDI to be valuable clinical metrics, motivating further research to be carried out at the state and national levels. These findings highlight health disparities in pediatric spine trauma.

Analysis of imaging risk factors for prognosis in children with spinal cord injury without radiologic abnormalities

This study aimed to identify imaging risk factors for spinal cord injury without radiologic abnormalities (SCIWORA) in children. We retrospectively analyzed the medical records and magnetic resonance imaging (MRI) findings of children with SCIWORA admitted to our hospital between January 1, 2012, and September 30, 2022. Univariate and binary logistic regression analyses were used to evaluate the prognostic impact of various factors including MRI type, maximum cross-sectional area of spinal cord injury, injury length, injury signal intensity ratio. The American Spinal Injury Association (ASIA) impairment scale (AIS) was used to assess neurological improvement of spinal cord injury. A total of 39 patients met the inclusion criteria, comprising three males and 36 females aged 6.38 ± 1.7 years. The injuries were predominantly dance-related (25 patients), followed by car accidents (4 patients), and falls/sprains (10 patients). Seventeen patients showed improvement in the AIS grade, while 22 did not. Binary logistic regression analysis revealed that the maximum cross-sectional area and length of the damaged segment were significant prognostic factors. Receiver operating characteristic curve analysis demonstrated an area under the curve (AUC) of 0.91, with a maximum cutoff value, sensitivity, and specificity of 0.12, 81.80%, and 88.20%, respectively, for the maximum damage cross-sectional area. For the damaged segment length, the AUC, maximum cutoff value, sensitivity, and specificity were 0.78, 6.50, 50%, and 41%, respectively. Whole-spine MRI plays a crucial role in the diagnosis and prognosis of pediatric patients with SCIWORA. The cross-sectional area and length of spinal cord injury are risk factors for poor prognosis.Level of evidence: IV.

Incidence and outcomes of pediatric patients with dual diagnosis of traumatic spinal cord injury and brain injury on an inpatient rehabilitation unit

BACKGROUND

Traumatic brain injury (TBI) and spinal cord injury (SCI) are diagnoses commonly encountered on the pediatric rehabilitation unit. However, there is limited evidence in the literature addressing the incidence of or rehabilitation outcomes in pediatric patients with a dual diagnosis of TBI and SCI.

OBJECTIVE

To determine incidence and functional outcomes of the dual diagnosis population.

DESIGN

Retrospective cohort study.

SETTING

Inpatient rehabilitation unit within an academic pediatric hospital.

PATIENTS

Pediatric patients admitted to a single inpatient rehabilitation unit with a diagnosis of traumatic SCI between 2006 and 2019. Fifty-four patient records were identified and 26 met inclusion criteria.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Presence of concomitant TBI in patients with diagnosed SCI.

RESULTS

Seven of 26 patients were given a dual diagnosis of TBI and SCI during their initial rehabilitation hospitalization. After review of charts, authors identified 12 additional patients with suspected dual diagnoses based on injury characteristics and symptoms. There were no significant differences in functional outcomes across diagnosis groups.

CONCLUSIONS

Incidence of dual diagnosis among pediatric patients with traumatic SCI was initially found to be 27%; the retrospective review indicated that TBI may be underdiagnosed in this patient population, and the dual diagnosis incidence may be as high as 73%. All patients had improved functional outcomes during their rehabilitation stays regardless of presence or absence of TBI.

Does race and insurance status play a role in high-grade renal trauma in the pediatric population? - An analysis from the traumatic renal injury collaborative in kids (TRICK) consortium

BACKGROUND

We sought to examine the potential role of race and insurance status on the presentation, management, and outcomes of high-grade renal trauma (HGRT) in a large trauma registry.

METHODS

A retrospective cohort study of a large, multi-center registry of high-grade pediatric renal trauma was performed. Patients < 18 years of age with HGRT (grades III, IV, and V) from 2007 to 2020 were included. Patient demographics, presenting characteristics, hospital courses, outcomes, and follow-ups were extracted and compared.

RESULTS

A total of 341 patients were initially identified, 32 were excluded. 66.3% were Caucasian(C), 27.5% were African American(AA), and 6.2% were Other races(O). 43.7% had public insurance,49.8% had private insurance and 6.5% were self-pay. Association of Race: AA patients had a higher rate of penetrating trauma (9% AA vs. 4% C, 0% Others, p = 0.002). Those with O and AA races presented at a younger age (9.5 yo O vs. 12.5 yo AA vs. 14 yo C, p = 0.001). However, no differences were found between race groups in the hospital course or outcome. Association of Insurance status: Those with public insurance presented with higher rates of bowel injury and blood transfusion, no differences were found in hospital course or outcome. Private insurance had higher Urology follow up rates (49% Private vs. 34.6% Public vs. 35% Self pay, p = 0.041).

CONCLUSIONS

Race and insurance status was associated with differences found on the mechanism of injury, transfusion rate and urology follow-up rate; however, they do not influence rates of surgical intervention, post-injury complications or mortality.

Pediatric Cervical Spine Trauma: A Narrative Review

STUDY DESIGN

Narrative review.

OBJECTIVE

To provide an updated overview of pediatric cervical spine trauma.

SUMMARY OF BACKGROUND DATA

Pediatric cervical spine trauma can cause debilitating morbidity and mortality and neurological impairment. The unique anatomic features of the developing cervical spine can predispose children to injuries.

METHODS

We reviewed the pediatric cervical spine trauma literature in PubMed and EMBASE.

RESULTS

Pediatric cervical spine injury occurs in 1%-2% of pediatric trauma. The most frequent cause is motor vehicle collisions, with sports-related injuries being more common in older children. Larger head-to-body ratios and tissue elasticity can predispose young children to a greater risk of injury higher in the craniocervical junction and cervical spine. Standardized protocols and classification systems, such as the Pediatric Cervical Spine Clearance Working Group protocol and the AO Spine Injury and Subaxial Cervical Spine Injury Classifications, are valuable in triage as well as for assessing the need for operative versus nonoperative management. In general, operative approaches and principles are similar to those in adults, with modern instrumentation and fusion techniques achieving high rates of successful arthrodesis.

CONCLUSIONS

Effective management and treatment of pediatric cervical spine injuries depends on early and accurate diagnosis, a thorough understanding of pediatric spinal anatomy, and a versatile surgical armamentarium.

Utilization of rehabilitation services in violent versus nonviolent traumatic spinal cord injury

BACKGROUND

Violence is the third leading cause of spinal cord injury (SCI) in the United States, and people with violence-related SCI have worse long-term outcomes compared to other traumatic SCI etiologies. Little is known, however, about the underlying reasons for these differences. Access to and utilization of rehabilitation services may differ in this population, but their outpatient care has not been previously investigated.

OBJECTIVE

To evaluate differences in utilization patterns of outpatient rehabilitation services between people with violence-related SCI and other traumatic SCI etiologies.

DESIGN

Retrospective cohort study.

SETTING

Academic tertiary care hospital system.

PATIENTS

A total of 41 patients with violence-related SCI residing in King County at the time of injury who completed inpatient rehabilitation (IPR) in our institution were identified from the hospital trauma registry and matched with 41 control patients with nonviolent traumatic SCI.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

The number of appointments attended, canceled, and missed during the first year after discharge from IPR were obtained by chart review for physical medicine & rehabilitation (PM&R) physicians and therapy services.

RESULTS

People with violence-related SCI had decreased follow-up with outpatient rehabilitation services after IPR discharge compared to non-violent traumatic SCI, including PM&R (2.50 ± 2.44 vs. 3.76 ± 2.21 visits, β = -1.28, p = .017), physical therapy (8.91 ± 11.02 vs. 17.57 ± 15.26, β = -9.79, p = .009), occupational therapy (4.28 ± 7.90 vs. 10.04 ± 14.42, β = -6.18, p = .033), and recreational therapy (0.293 ± 0.955 vs. 1.37 ± 2.86, β = -1.07, p = .035). The rate of missed appointments was also higher among people with violence-related SCI compared to controls for PM&R (25.2% ± 28.5% vs. 9.9% ± 16.5%, β = 14.6%, p = .014) and physical therapy (26.0% ± 32.0% vs 4.2% ± 13.2%, β = 22.1%, p = .009).

CONCLUSIONS

Individuals with violence-related SCI had fewer follow-up appointments with PM&R physicians and other allied health professionals and were more likely to miss scheduled appointments compared to other traumatic SCI etiologies. Decreased outpatient follow-up may affect long-term outcomes for people with violence-related SCI.

Addressing the Impact of Race and Ethnicity on Musculoskeletal Spine Care in the United States

➤ Despite being a social construct, race has an impact on outcomes in musculoskeletal spine care.➤ Race is associated with other social determinants of health that may predispose patients to worse outcomes.➤ The musculoskeletal spine literature is limited in its understanding of the causes of race-related outcome trends.➤ Efforts to mitigate race-related disparities in spine care require individual, institutional, and national initiatives.

Clinical characteristics of pediatric traumatic spinal cord injury in China: A single center retrospective study

OBJECTIVE

To investigate the clinical characteristics of children with traumatic spinal cord injury (SCI) admitted to a research rehabilitation center between 2011 and 2020, with a view to generate crucial data for understanding and prevention of pediatric traumatic SCI.

DESIGN

Retrospective cohort study.

SETTING

The National Rehabilitation Research Center of China, Beijing, China.

PARTICIPANTS

Medical records and imaging data of children with traumatic SCI admitted to the rehabilitation research center from 2011 to 2020.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Data on age, sex, cause of injury, neurological level of injury, impairment scale of SCI and details of spine fracture or dislocation were all collected and analyzed.

RESULTS

A total of 351 patients were included in the study, including 133 males (37.9%) and 218 females (62.1%). There were 231 cases (65.8%) without spine fracture or dislocation. SCI without fracture or dislocation (SCIWORA) was the most common in children between the age of 5 and 14 years (77.9%), and injuries caused by sports were the most common in girls (90.8%). Among sports injuries, those due to a special dance movement called "Xia-Yao" in Chinese, which involves hyperextension of the trunk, constituted the majority, with the neurological level of injuries located predominantly in the middle (34.6%) and lower (44.2%) thoracic levels.

CONCLUSION

Girls between the ages of 5 and 14 years constituted the majority of SCIWORA injuries at the thoracic levels, which were caused mainly by "Xia-Yao". Overall, careful attention should be paid to prevent this kind of injury in children.

Real Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) in Pediatrics: A Clinical Case Report and Literature Review

Spinal cord injury without radiological abnormality (SCIWORA) was first reported in 1974. The term was used to define "clinical symptoms of traumatic myelopathy without signs of fracture or spine instability on X-ray or CT scan." With the emergence of MRI, the gold standard method to identify spinal cord injuries, about two-thirds of former SCIWORA cases were found to have pathological findings, and, as such, the term has taken on an ambiguous meaning in the literature. We describe the clinical case of a 17-year-old boy who was admitted to the emergency department of a tertiary hospital after a fall during a soccer game. He suffered spinal and cranioencephalic trauma. A few minutes later, the boy began to show decreased strength in the right upper limb and lower limbs, as well as changes in sensation in the right hemibody. On objective examination, the boy presented a Glasgow Coma Scale score of 15 and the American Spinal Injury Association Impairment Scale D, with partial improvement of initial symptoms of monoparesis of the right lower limb. There were no other changes, specifically at the sensory level. The patient underwent a CT and MRI of the spine that showed no fractures, instability, or appreciable medullary signal changes. Electromyography was normal. Based on the clinical history and imaging findings, real SCIWORA was diagnosed. The patient was admitted to an inpatient rehabilitation program. At a follow-up visit two months later, a complete reversal of signs and symptoms was confirmed. The prognosis of this pathology depends on the extent of the spinal cord injury, as evidenced by MRI. Although neurological improvement when severe deficit is present at initial presentation is unlikely, most patients with incomplete neurological damage show good recovery. The absence of visible changes on MRI is associated with a better prognosis.

A systematic review and meta-analysis of the global epidemiology of pediatric traumatic spinal cord injuries

Despite being relatively rare, pediatric traumatic spinal cord injury (TSCI) is a debilitating event with high morbidity and long-term damage and dependency. This study aims to provide insight on the epidemiological characteristics of pediatric TSCI worldwide. The studies were included if they provided data for the pediatric population with the diagnosis of TSCI. Information sources included PubMed, Embase, Web of Science, and Scopus. All databases were searched from 1990 to April 2023. The quality of included studies was evaluated by Joanna Briggs Institute Critical Appraisal Tools. The results of the meta-analysis were presented as forest plots. PROSPERO Registration code: CRD42020189757. We identified 87 studies from 18 developed and 11 developing countries. Of the 87 studies evaluated, 52 studies were considered medium quality, 27 studies were considered high quality, and 8 studies were considered low quality. In developed countries, the proportion of TSCIs occurring in patients aged 0-15 years was 3% (95% CI: 2.2%; 3.9%), while in developing countries, it was 4.5% (95% CI: 2.8%; 6.4%). In developed countries, the pooled incidence of pediatric TSCI was 4.3/millions of children aged 0-15/year (95% CI: 3.1; 6.0/millions children aged 0-15/year) and boys comprised 67% (95% CI: 63%; 70%) of cases. The most prevalent level of injury was cervical (50% [95% CI: 41%; 58%]). The frequency of SCI Without Obvious Radiological Abnormality (SCIWORA) was 35% (95% CI: 18%; 54%) among children 0-17 years. The most common etiology in developed countries was transport injuries (50% [95% CI: 42%; 57%]), while in developing countries falls were the leading cause (31% [95% CI: 20%; 42%]). The most important limitation of our study was the heterogeneity of studies in reporting age subgroups that hindered us from age-specific analyses.   Conclusion: Our study provided accurate estimates for the epidemiology of pediatric TSCI. We observed a higher proportion of pediatric TSCI cases in developing countries compared to developed countries. Furthermore, we identified distinct epidemiological characteristics of pediatric TSCI when compared to adult cases and variations between developing and developed countries. Recognizing these unique features allows for the implementation of cost-effective preventive strategies aimed at reducing the incidence and burden of TSCI in children. What is Known: • Pediatric Traumatic Spinal Cord Injury (TSCI) can have profound physical and social consequences for affected children, their families, and society as a whole. • Epidemiological insights are vital for they provide the data and understanding needed to the identification of vulnerable populations, aiding in the development of targeted prevention strategies and effective resource allocation. What is New: • The estimated incidence of pediatric TSCI in developed countries is 4.3 cases per million children aged 0-15. The proportion of pediatric TSCI cases in relation to all-age TSCI cases is 3% in developed countries and 4.5% in developing countries. • The etiology of TSCI in pediatric cases differs between developing and developed countries. In developed countries, transport injuries are the most prevalent cause of pediatric TSCI, while falls are the least common cause. Conversely, in developing countries, falls are the leading cause of pediatric TSCI.

Nationwide emergency department visits for pediatric traumatic spinal cord injury in the United States, 2016-2020

Introduction

Traumatic spinal cord injury (tSCI) is a debilitating neurological condition resulting in lifelong disability for many individuals. The primary objectives of our study were to describe national trends in incident emergency department (ED) visits for tSCI among children (less than 21 years) in the United States, and to determine the proportion of visits that resulted in immediate hospitalization each year, including stratified by age and sex. Secondary objectives were to examine associations between select characteristics and hospitalization following tSCI, as well as to assess sports-related tSCIs over time, including by individual sport and geographic region.

Methods

We used the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample to identify ED visits among children between January 2016 and December 2020 for incident tSCI. Diagnosis codes were used to identify tSCI and sports-related injury etiologies. Census Bureau data were used to approximate annual rates of pediatric ED visits for tSCI per 100,000 children. Unconditional logistic regression modeling assessed whether select factors were associated with hospital admission.

Results

We found that the annual ED visit rate for tSCI remained relatively stable between 2016 and 2020, with approximately 2,200 new all-cause pediatric ED visits for tSCI annually. Roughly 70% of ED visits for tSCI resulted in hospitalization; most ED visits for tSCI were by older children (15-20 years) and males, who were also more often admitted to the hospital. Notable secondary findings included: (a) compared with older children (15-20 years), younger children (10-14 years) were less likely to be hospitalized immediately following an ED visit for tSCI; (b) patient sex and race were not associated with hospital admission; and (c) American tackle football was the leading cause of sports-related ED visits for tSCI among children. Our findings also suggest that the proportion of sports-related tSCI ED visits may have increased in recent years.

Discussion

Future research should further examine trends in the underlying etiologies of pediatric tSCI, while assessing the effectiveness of new and existing interventions aimed at tSCI prevention.

An evidence-based approach to the recovery of bladder and bowel function after pediatric spinal cord injury

INTRODUCTION

Bladder dysfunction and associated complications of the urinary system negatively impact the quality of life in children living with spinal cord injury (SCI). Pediatric lower urinary tract deficits include bladder over-activity, inefficient emptying, decreased compliance, and incontinence. Recent evidence in adults with SCI indicates significant improvements in bladder capacity and detrusor pressure following participation in an activity-based recovery locomotor training (ABR-LT) rehabilitative program. Additionally, anecdotal self-reports from parents in our Pediatric NeuroRecovery Program reference changes in bladder function, ranging from awareness of bladder fullness to gains in voluntary control while undergoing ABR-LT.

CASE PRESENTATION

In a within-subjects repeated measures study, we investigated the effect of ABR-LT on bladder function in three children (ages: 2.5, 3, and 6 years) who sustained upper motor neuron SCI. Each child received at least 60 sessions of ABR-LT (5x/week) for 12-14 weeks. Bladder function was assessed via urodynamics and the Common Data Elements questionnaires. Awareness of bladder filling during cystometry was present in all children and detrusor leak point pressure (LPP) was reduced post-ABR-LT relative to pre-training. A decrease in LPP after locomotor training was observed in all three participants. One out of the three participants had substantial improvements in bladder capacity post-ABR-LT and experienced less bowel incontinence following training.

DISCUSSION

Like our evidence in adults, the changes in bladder function suggest an interaction between lumbosacral networks regulating spinal reflex control of bladder filling, voiding, and afferent input (including potential descending supraspinal commands) and those activated by ABR-LT. Locomotor training may be associated with increased bladder capacity, enhanced perception of bladder filling, and decreased LPP as well as improvements in bowel control in pediatric SCI. This research suggests that children and adolescents with traumatic SCI could experience dynamic improvements in bladder and bowel function with the aid of various therapies. Studies assessing the durability of training on the recovery of bladder and bowel dysfunction in children with SCI are needed.

Global Epidemiology of Pediatric Traumatic Spine Injury: A Systematic Review and Meta-Analysis

OBJECTIVE

Traumatic spine injury (TSI) leads to significant morbidity and mortality in children. However, the global epidemiology of pediatric TSI is currently unknown. We conducted a systematic review and meta-analysis to estimate the global incidence of pediatric TSI and the burden of cases.

METHODS

PubMed, Embase, and Scopus were searched for reports in June 2021 and updated in March 2023 with no restrictions on language or year of publication. A meta-analysis was conducted to estimate the global incidence of pediatric TSI and, subsequently, the number of cases of pediatric TSI worldwide and the proportion requiring spine surgery.

RESULTS

Of 6557 studies, 25 met the inclusion criteria. Road traffic accidents (64%) were responsible for most cases reported in the literature, followed by falls (18%). The global incidence of TSI in children aged ≤20 years was estimated to be 14.24 of 100,000 children, or 375,734 children, with an estimated 114,975 requiring spine surgery. Across the World Bank income classification groups, lower middle-income countries had the highest pediatric TSI case burden (186,886 cases, with 57,187 requiring spine surgery). Across the World Health Organization regions, countries in the Southeast Asia region had the largest number of projected cases at 88,566, with 27,101 requiring surgical management, followed closely by the African region, with 87,235 projected cases and 26,694 requiring surgical management.

CONCLUSIONS

Pediatric TSI represents a large healthcare burden globally. Interventions targeting both injury prevention and strengthening of neurosurgical capacity, especially in low resource settings, are needed to address this global health challenge.

Dual diagnosis of TBI and SCI: an epidemiological study in the pediatric population

Introduction

Dual diagnosis (DD) with traumatic brain injury (TBI) and spinal cord injury (SCI) poses clinical and rehabilitation challenges. While comorbid TBI is common among adults with SCI, little is known about the epidemiology in the pediatric population. The primary objective of this study was to evaluate the prevalence of TBI among children in the United States hospitalized with SCI. Secondary objectives were to compare children hospitalized with DD with those with isolated SCI with regards to age, gender, race, hospital length of stay, and hospital charges.

Methods

A retrospective analysis of hospital discharges among children aged 0-18 years occurring between 2016-2018 from U.S. hospitals participating in the Kids' Inpatient Database. ICD-10 codes were used to identify cases of SCI, which were then categorized by the presence or absence of comorbid TBI.

Results

38.8% of children hospitalized with SCI had a co-occurring TBI. While DD disproportionately occurred among male children (67% of cases), when compared with children with isolated SCI, those with DD were not significantly more likely to be male. They were more likely to be Caucasian. The mean age of children with DD (13.2 ± 5.6 years) was significantly less than that of children with isolated SCI (14.4 ± 4.3 years). DD was associated with longer average lengths of stay (6 versus 4 days) and increased mean total hospital charges ($124,198 versus $98,089) when compared to isolated SCI.

Conclusion

Comorbid TBI is prevalent among U.S. children hospitalized with SCI. Future research is needed to better delineate the impact of DD on mortality, quality of life, and functional outcomes.

Racial, Gender, and Neighborhood-Level Disparities in Pediatric Trauma Care

BACKGROUND

Disparities in trauma outcomes and care are well established for adults, but the extent to which similar disparities are observed in pediatric trauma patients requires further investigation. The objective of this study was to evaluate the unique contributions of social determinants (race, gender, insurance status, community distress, rurality/urbanicity) on trauma outcomes after controlling for specific injury-related risk factors.

STUDY DESIGN

All pediatric (age < 18) trauma patients admitted to a single level 1 trauma center with a statewide, largely rural, catchment area from January 2010 to December 2020 were retrospectively reviewed (n = 14,398). Primary outcomes were receipt of opioids in the emergency department, post-discharge rehabilitation referrals, and mortality. Multivariate logistic regressions evaluated demographic, socioeconomic, and injury characteristics. Multilevel logistic regressions evaluated area-level indicators, which were derived from abstracted home addresses.

RESULTS

Analyses adjusting for demographic and injury characteristics revealed that Black children (n = 6255) had significantly lower odds (OR = 0.87) of being prescribed opioid medications in the emergency department compared to White children (n = 5883). Children living in more distressed and rural communities had greater odds of receiving opioid medications. Girls had significantly lower odds (OR = 0.61) of being referred for rehabilitation services than boys. Post hoc analyses revealed that Black girls had the lowest odds of receiving rehabilitation referrals compared to Black boys and White children.

CONCLUSION

Results highlight the need to examine both main and interactive effects of social determinants on trauma care and outcomes. Findings reinforce and expand into the pediatric population the growing notion that traumatic injury care is not immune to disparities.

Social determinants of health as drivers of inequities in pediatric injury

A child's social determinants of health (SDH), including their neighborhood environment, insurance status, race and ethnicity, English language proficiency and geographic location, all significantly impact their risk of injury and outcomes after injury. Children from socioeconomically disadvantaged neighborhoods experience overall higher rates of injury and different types of injuries, including higher rates of motor vehicle-, firearm-, and violence-related injuries. Similarly, children with public insurance or no insurance, as a proxy for lower socioeconomic status, experience higher rates of injuries including firearm-related injuries and non-accidental trauma, with overall worse outcomes. Race and associated racism also impact a child's risk of injury and care received after injury. Black children, Hispanic children, and those from other minority groups disproportionately experience socioeconomic disadvantage with sequelae of injury risk as described above. Even after controlling for socioeconomic status, there are still notable disparities with further evidence of racial inequities and bias in pediatric trauma care after injury. Finally, where a child lives geographically also significantly impacts their risk of injury and available care after injury, with differences based on whether a child lives in a rural or urban area and the degree of state laws regarding injury prevention. There are clear inequities based on a child's SDH, most predominantly in a child's risk of injury and the types of injuries they experience. These injuries are preventable and the SDH provide potential upstream targets in injury prevention efforts.

Analysis of Physeal Fractures from the United States National Trauma Data Bank

Background: Pediatric long-bone physeal fractures can lead to growth deformities. Previous studies have reported that physeal fractures make up 18–30% of total fractures. This study aimed to characterize physeal fractures with respect to sex, age, anatomic location, and Salter–Harris (SH) classification from a current multicenter national database. Methods: A retrospective cohort study was performed using the 2016 United States National Trauma Data Bank (NTDB). Patients ≤ 18 years of age with a fracture of the humerus, radius, ulna, femur, tibia, or fibula were included. Results: The NTDB captured 132,018 patients and 58,015 total fractures. Physeal fractures made up 5.7% (3291) of all long-bone fractures, with males accounting for 71.0% (2338). Lower extremity physeal injuries comprised 58.6% (1929) of all physeal fractures. The most common site of physeal injury was the tibia comprising 31.8% (1047), 73.9% (774) of which were distal tibia fractures. Physeal fractures were greatest at 11 years of age for females and 14 years of age for males. Most fractures were SH Type II fractures. Discussion and Conclusions: Our analysis indicates that 5.7% of pediatric long-bone fractures involved the physis, with the distal tibia being the most common. These findings suggest a lower incidence of physeal fractures than previous studies and warrant further investigation.

DTI of chronic spinal cord injury in children without MRI abnormalities (SCIWOMR) and with pathology on MRI and comparison to severity of motor impairment

STUDY DESIGN

This investigation was a cohort study that included: 36 typically developing (TD) children and 19 children with spinal cord lesions who underwent spinal cord MRI.

OBJECTIVES

To investigate diffusion tensor imaging (DTI) cervical and thoracic spinal cord changes in pediatric patients that have clinically traumatic and non-traumatic spinal cord injury (SCI) without MR (SCIWOMR) abnormalities.

SETTING

Thomas Jefferson University, Temple University, Shriners Hospitals for Children all in Philadelphia, USA.

METHODS

36 TD children and 19 children with spinal cord lesions that represent either a chronic traumatic acquired SCI or chronic non-traumatic SCI (≥6 months post injury), age range, 6-16 years who underwent cervical and thoracic spinal cord MRI in 2014-2017. Additionally DTI was correlated to clinical American Spinal Injury Association Impairment Scale (AIS).

RESULTS

Both SCIWOMR and MRI positive (+) groups showed abnormal FA and RD DTI values in the adjacent MRI-normal appearing segments of cephalad and caudal spinal cord compared to TD. The FA values demonstrated perilesional abnormal DTI findings in the middle and proximal segments of the cephalad and caudal cord in the SCIWOMR AIS A/B group compared to SCIWOMR AIS C/D group.

CONCLUSIONS

We found DTI changes in children with SCIWOMR with different causes of spinal lesions. We also investigated the relationship between DTI and clinical AIS scores. This study further examined the potential diagnostic value of DTI and should be translatable to adults with spinal cord lesions.

Predictors of thoracic and lumbar spine injuries in patients with TBI: A nationwide analysis

OBJECTIVE

Cervical spine injury screening is common practice for traumatic brain injury (TBI) patients. However, risk factors for concomitant thoracolumbar trauma remain unknown. We characterized epidemiology and clinical risk for concomitant thoracolumbar trauma in TBI.

METHODS

We conducted a multi-center, retrospective cohort analysis of TBI patients in the National Trauma Data Bank from 2011-2014 using multivariable logistic regression.

RESULTS

Out of 768,718 TBIs, 46,654 (6.1%) and 42,810 (5.6%) patients were diagnosed with thoracic and lumbar spine fractures, respectively. Only 11% of thoracic and 7% of lumbar spine fracture patients had an accompanying spinal cord injury at any level. The most common mechanism of injury was motor vehicle accident (67% of thoracic and 71% and lumbar fractures). Predictors for both thoracic and lumbar fractures included moderate (thoracic: OR 1.26, 95%CI 1.21-1.31; lumbar: OR 1.13, 95%CI 1.08-1.18) and severe Glasgow Coma Scale (GCS) score (OR 1.71, 95%CI 1.67-1.75; OR 1.17, 95%CI 1.13-1.20) compared to mild; epidural hematoma (OR 1.36, 95%CI 1.28-1.44; OR 1.1, 95%CI 1.04-1.19); lower extremity injury (OR 1.38, 95%CI 1.35-1.41; OR 2.50, 95%CI 2.45-2.55); upper extremity injury (OR 2.19, 95%CI 2.14-2.23; OR 1.15, 95%CI 1.13-1.18); smoking (OR 1.09, 95%CI 1.06-1.12; OR 1.12, 95%CI 1.09-1.15); and obesity (OR 1.39, 95%CI 1.34-1.45; OR 1.29, 95%CI 1.24-1.35). Thoracic injuries (OR 4.45; 95% CI 4.35-4.55) predicted lumbar fractures, while abdominal injuries (OR 2.02; 95% CI 1.97-2.07) predicted thoracic fractures.

CONCLUSIONS

We identified GCS, smoking, upper and lower extremity injuries, and obesity as common risk factors for thoracic and lumbar spinal fractures in TBI.

Pediatric Thoracolumbar Spinal Injuries in United States Trauma Centers

OBJECTIVES

Injuries are the leading cause of morbidity and mortality in children ages 1 to 18 years. There are limited studies about pediatric thoracolumbar (TL) spinal injuries; the purpose of this study was to characterize TL spinal injuries among pediatric patients evaluated in US trauma centers.

METHODS

This was a retrospective cohort study of the National Trauma Data Bank. Patients aged 1 to 18 years with a thoracic or lumbar spinal injury sustained by blunt trauma during calendar years 2011 through 2016 were included. Cervical spinal injuries, death before arrival, or penetrating trauma were excluded. The data was abstracted, and missing data was addressed by imputations. Data was analyzed using descriptive statistics and multinomial logistic regressions.

RESULTS

A total of 20,062 patients were included in the study. Thoracolumbar spinal injuries were more commonly sustained by 16- to 17-year-olds (45.7%), boys (56.6%), and White (74.8%). The injuries were often from a motor vehicle collision (MVC) (55.2%) and resulted in a bone injury (82.3%). Mechanism of injury and age were significant in predicting injury type. A fall was more likely than MVC to result in disc injury (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.24-2.33), strain injury (OR, 1.18; 95% CI, 1.05-1.34), or cord injury (OR, 1.27; 95% CI, 1.12-1.45). Younger children were more likely than adolescents to present with disc injury (OR, 2.79; 95% CI, 1.75-4.45), cord injury (OR, 1.46; 95% CI, 1.18-1.81), or strain injury (OR, 1.37; 95% CI, 1.09-1.72).

CONCLUSIONS

To our knowledge, this is the largest pediatric TL spinal study. Clinicians should consider TL spinal injuries when adolescents present after an MVC, and specifically, TL spinal cord injuries when young children present after a fall. Additionally, pediatric TL spinal injury prevention should highlight motor vehicle and fall safety.

Sociodemographic, geographic and clinical factors associated with functional outcome and discharge location in US inpatient rehabilitation settings

OBJECTIVE

To assess the impact of sociodemographic factors, clinical factors and regional differences on both patients' functional outcome and discharge location in U.S. inpatient rehabilitation settings.

METHODS

Using eRehabData, 536,453 admissions was used for functional outcome analyses (based on FIM gain) while 259,308 admissions was used for the discharge location analyses. Regression models were used to look at both outcomes.

RESULTS

Having private insurance and being young and male was associated with the higher FIM gains while being African American, widowed, and living in the Midwest was associated with the lower FIM gains. Furthermore, having private insurance, being young, male, married and African American or Hispanic was associated with the lower odds of being discharged to a skilled nursing facility while living in the Midwest was associated with the greatest odds of being discharged to a skilled nursing facility. Clinical factors such as days from onset and length of stay also had a significant effect on both outcomes.

CONCLUSION

Our findings suggest that, in the U.S., one of the challenges to successful recovery in the inpatient rehabilitation setting includes insurance status (Medicare/Medicaid), race (African American) but also regional differences (Midwest) and length of stay.

Pediatric Traumatic Spinal Cord Injury in the United States: A National Inpatient Analysis

BACKGROUND

Traumatic spinal cord injury (tSCI) is a debilitating neurological condition often associated with lifelong disability. Despite this, there are limited data on pediatric tSCI epidemiology in the United States.

OBJECTIVES

Our primary objective was to estimate tSCI hospitalization rates among children, including by age, sex, and race. Secondary objectives were to characterize tSCI hospitalizations and examine associations between sociodemographic characteristics and tSCI etiology.

METHODS

We used the 2016 Kids' Inpatient Database to examine tSCI hospitalizations among children (<21 years). Descriptive statistics were used to report individual and care setting characteristics for initial tSCI hospitalizations. We used Census Bureau data to estimate tSCI hospitalization rates (number of pediatric tSCI hospitalizations / number of US children) and logistic regression modeling to assess associations between documented sociodemographic characteristics and injury etiology.

RESULTS

There were 1.48 tSCI admissions per 100,000 children; highest rates of hospitalization involved older (15-20 years), male, and Black children. Hospitalization involving male (adjusted odds ratio [AOR] 0.43; 95% CI, 0.33-0.58) or Black (AOR 0.37; 95% CI, 0.25-0.55) children were less likely to involve a motor traffic accident. Hospitalizations of Black children were significantly more likely to have a diagnosis of tSCI resulting from a firearm incident (AOR 18.97; 95% CI, 11.50-31.28) or assault (AOR 11.76; 95% CI, 6.75-20.50) compared with hospitalizations of White children.

CONCLUSION

Older, male, and Black children are disproportionately burdened by tSCI. Implementation of broad health policies over time may be most effective in reducing pediatric tSCI hospitalizations and preventable injuries.

Spina Bifida Occulta Is a Risk Factor for Spinal Cord Injury Without Fracture or Dislocation for Children Performing a Backbend During Dance

OBJECTIVE

This study aimed to explore the clinical features and outcomes of children with spinal cord injury (SCI) without fracture or dislocation.

METHODS

The clinical data of children with SCI without fracture or dislocation in this retrospective study were collected in Chongqing, China (January 2010 to December 2021). We collected patient demographics at admission including age, gender, cause, level, and severity of the injury in admission and complications. Reports from radiologic imaging were reviewed to identify spina bifida occulta (SBO). Neurological function was evaluated using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) for an SCI.

RESULTS

A total of 74 children with SCI (male, 27%; female, 73%; male-to-female ratio, 1:2.7; average age, 5.7 years) were included. The main cause of injury was backbend during the dance (34 patients, 45.9%, including 2 patients who hugged back falling backward), followed by traffic accidents (17 patients, 23%). Children with backbend-related SCI were older than other children (6.9 vs. 4.9 years old, P < 0.001). When reviewing all radiological images, it was found that 20 (27%) patients with SCI had SBO. The proportion of SCI with SBO caused by backbend was considerably higher than those caused by non-backbend (41.2 vs. 15%, P = 0.012). The AIS were 22 (29.7%), 4 (5.4%), 8 (10.8%), 31 (41.9%), and 9 (12.2%) in A, B, C, D, and E, respectively. The prognosis was poorer in the backbend during dancing than other causes of injury (p = 0.003).

CONCLUSION

This study showed that backbend during the dance was the main cause of children's SCI without fracture or dislocation in Chongqing, China. The prognosis was poorer in those children than in other causes of injury. Meanwhile, we have established an association between SBO and SCI for children performing a backbend during the dance.

Seatbelts Save Lives, and Spines, in Motor Vehicle Accidents: A Review of the National Trauma Data Bank in the Pediatric Population

STUDY DESIGN

Database study.

OBJECTIVE

The purpose of this study was to use a large, nationwide database to determine prevalence of pediatric spine fractures in the United States, associated injuries, mechanisms of injury (MOI), use of safety devices, and mortality rates.

SUMMARY OF BACKGROUND DATA

Spinal fractures account for 1% to 2% of pediatric injuries. However, they are associated with significant comorbidities and complications. Motor vehicle accidents (MVAs) are most responsible for increased incidence observed.

METHODS

Retrospective review of National Trauma Data Bank between 2009 and 2014 (analysis in 2019) for all vertebral fractures in patients under 18 years of age. Subanalysis included those in MVAs where protective device use data were available. Patient demographics, MOI, geographical and anatomical region of injury, concomitant musculoskeletal/organ injury, protective device usage, hospital length of stay, surgical procedures, and mortality were all analyzed.

RESULTS

A total of 34,563 patients with 45,430 fractured vertebrae included. Median age was 15 years. Most fractures (63.1%) occurred in patients aged 15 to 17 years, most frequent MOI was MVA (66.8%), and most common geographic location was the South (38%). Males sustained more spine fractures than females, overall (58.4% vs. 41.6%; P < 0.001) and in MVAs (54.4% vs. 45.6%; P < 0.001). Those in MVAs wearing seatbelts had lower odds of cranial (29.6% vs. 70.4%; odds ratio [OR] = 0.85, 95% confidence interval [CI]: 0.82-0.89; P < 0.001) and thoracic (30.1% vs. 69.9%; OR = 0.88, 95% CI: 0.84-0.91; P < 0.001) organ injury, multivertebral (30% vs. 70%; OR = 0.78, 95% CI: 0.73-0.83; P < 0.001) and concomitant nonvertebral fractures (30.9% vs. 69.1%; OR = 0.89, 95% CI:0.73-0.83; P < 0.001), and 21% lower odds of mortality (29.3% vs. 70.7%; OR = 0.79, 95% CI: 0.66-0.94; P = 0.009). Over 70% of drivers were not restrained during MVA, with majority of seatbelt violations incurred by males, ages 15 to 17, in the South.

CONCLUSION

Over 60% of pediatric spinal fractures occur in children aged 15 to 17 years, coinciding with the beginning of legal driving. MVA is the most common cause and has significant association with morbidity/mortality. Nearly two- thirds pediatric spinal fractures sustained in MVAs occurred without seatbelts. Absence of seatbelts associated with >20% greater odds of mortality. Ensuring new drivers wear protective devices can greatly reduce morbidity/ mortality associated with MVA.Level of Evidence: 3.

Systematic Review of Racial, Socioeconomic, and Insurance Status Disparities in the Treatment of Pediatric Neurosurgical Diseases in the United States

BACKGROUND

Increasing light is being shed on how race, insurance, and socioeconomic status (SES) may be related to outcomes from disease in the United States. To better understand the impact of these health care disparities in pediatric neurosurgery, we performed a systematic review of the literature.

METHODS

We conducted a systematic review using PRISMA guidelines and MeSH terms involving neurosurgical conditions and racial, ethnic, and SES disparities. Three independent reviewers screened articles and analyzed texts selected for full analysis.

RESULTS

Thirty-eight studies were included in the final analysis, of which all but 2 were retrospective database reviews. Thirty-four studies analyzed race, 22 analyzed insurance status, and 13 analyzed SES/income. Overall, nonwhite patients, patients with public insurance, and patients from lower SES were shown to have reduced access to treatment and greater rates of adverse outcomes. Nonwhite patients were more likely to present at an older age with more severe disease, less likely to undergo surgery at a high-volume surgical center, and more likely to experience postoperative morbidity and mortality. Underinsured and publicly insured patients were more likely to experience delay in surgical referral, less likely to undergo surgical treatment, and more likely to experience inpatient mortality.

CONCLUSIONS

Health care disparities are present within multiple populations of patients receiving pediatric neurosurgical care. This review highlights the need for continued investigation into identifying and addressing health care disparities in pediatric neurosurgery patients.

Racial Disparities in Health Care Resource Utilization After Pediatric Cervical and/or Thoracic Spinal Injuries

OBJECTIVE

This study aimed to investigate the impact of race on hospital length of stay (LOS) and hospital complications among pediatric patients with cervical/thoracic injury.

METHODS

A retrospective cohort was performed using the 2017 admission year from 753 facilities utilizing the National Trauma Data Bank. All pediatric patients with cervical/thoracic spine injuries were identified using the ICD-10-CM diagnosis coding system. These patients were segregated by their race, non-Hispanic white (NHW), non-Hispanic black (NHB), non-Hispanic Asian (NHA), and Hispanic (H). Demographic, hospital variable, hospital complications, and LOS data were collected. A linear and logistic multivariate regression analysis was performed to determine the risk ratio for hospital LOS as well as complication rate, respectively.

RESULTS

A total of 4,125 pediatric patients were identified. NHB cohort had a greater prevalence of cervical-only injuries (NHW: 37.39% vs. NHB: 49.93% vs. NHA: 34.29% vs. H: 38.71%, P < 0.001). While transport accident was most common injury etiology for both cohorts, NHB cohort had a greater prevalence of assault (NHW: 1.53% vs. NHB: 17.40% vs. NHA: 2.86% vs. H: 6.58%, P < 0.001) than the other cohorts. Overall complication rates were significantly higher among NHB patients (NHW: 9.39% vs. NHB: 15.12% vs. NHA: 14.29% vs. H: 13.60%, P < 0.001). Compared with the NHW cohort, NHB, NHA, and H had significantly longer hospital LOS (NHW: 6.15 ± 9.03 days vs. NHB: 9.24 ± 20.78 days vs. NHA: 9.09 ± 13.28 days vs. H: 8.05 ± 11.45 days, P < 0.001). NHB race was identified as a significant predictor of increased LOS on multivariate regression analysis (risk ratio: 1.14, 95% confidence interval: 0.46, 1.82; P = 0.001) but not hospital complications (P = 0.345).

CONCLUSIONS

Race may significantly impact health care resource utilization following pediatric cervical/thoracic spinal trauma.

American football is the youth sporting activity most commonly associated with acute vertebral fractures

OBJECTIVES

Athletics confer cardiovascular fitness and improved cognitive processing in pediatric populations. However, one risk of sports participation is acute vertebral fracture, an injury with significant morbidity. It is currently unknown which sports represent the highest risk of acute vertebral fracture in pediatric populations. This study seeks to identify the youth sporting activities most commonly associated with acute vertebral fractures presenting to United States (U.S.) emergency departments (EDs).

METHODS

This cross-sectional, retrospective study queries the National Electronic Injury Surveillance System database to report national weighted estimates and demographic characteristics of pediatric patients with acute vertebral fractures presenting to U.S. EDs.

RESULTS

The mean annual incidence of estimated acute vertebral fractures over the study period was 1,672 (C.I. 1,217-2,126). From 2000-2001 (N = 4,030; C.I. 2,934-5,125) to 2016-2017 (N = 2,559; C.I. 1,681-3,438), there was no significant change in the estimated rate of sports-related acute vertebral fractures in pediatric patients (p = 0.09). American football was identified as the sport most frequently associated with acute vertebral fractures (23.4%; C.I. 17.6-29.3%). We found no appreciable change in the rate of football-related acute vertebral fractures over time, with 48.2% (C.I. 37.3-59.0%) occurring from 2000 to 2008 and 51.8% (C.I. 41.0-62.7%) from 2009 to 2017.

CONCLUSIONS

While sports-related acute vertebral fractures remain rare injuries in pediatric populations, we identify youth football as the sport associated with the highest risk of such injuries. Despite decreasing football participation rates over our study period, the annual incidence of football-associated acute vertebral fractures has not exhibited a proportional decline. Our findings raise concern that the relative risk of acute vertebral fracture associated with youth football has not significantly decreased over time. Elimination of dangerous tackling technique, improvement in helmet fit and technology, and availability of on-site medical care may contribute to decreased estimates in the future.

Psychiatric Evaluation and Management in Pediatric Spinal Cord Injuries: a Review

PURPOSE OF REVIEW

To summarize current key recommendations in the evaluation and management of mental health disorders associated with spinal cord injuries (SCI) among pediatric patients, based on a review of recent evidence-based literature and clinical experience.

RECENT FINDINGS

Anticipating potential mental health risks among youth with SCI and implementing early multidisciplinary management improves physical and mental health outcomes. When caregivers of youth with SCI model healthy coping strategies, it promotes healthy coping strategies in patients themselves. Peer mentor programs can be instrumental in patient adjustment, improve mental health, and aid in recovery. Pediatric SCI is particularly impactful on a child's development and individuation. Early involvement of a mental health team while in the hospital can help with the initial adjustment period and address psychiatric concerns that might interfere with recovery. The transition from the hospital to home is a period of vulnerability for individuals with SCI.

Cervical Spine Imaging and Injuries in Young Children With Non-Motor Vehicle Crash-Associated Traumatic Brain Injury

OBJECTIVES

The aim of this study was to evaluate cervical magnetic resonance imaging (MRI) and computed tomography (CT) practices and cervical spine injuries among young children with non-motor vehicle crash (MVC)-associated traumatic brain injury (TBI).

METHODS

We performed a retrospective study of a stratified, systematic random sample of 328 children younger than 2 years with non-MVC-associated TBI at 4 urban children's hospitals from 2008 to 2012. We defined TBI etiology as accidental, indeterminate, or abuse. We reported the proportion, by etiology, who underwent cervical MRI or CT, and had cervical abnormalities identified.

RESULTS

Of children with non-MVC-associated TBI, 39.4% had abusive head trauma (AHT), 52.2% had accidental TBI, and in 8.4% the etiology was indeterminate. Advanced cervical imaging (CT and/or MRI) was obtained in 19.1% of all children with TBI, with 9.3% undergoing MRI and 11.7% undergoing CT. Cervical MRI or CT was performed in 30.9% of children with AHT, in 11.7% of accidental TBI, and in 10.7% of indeterminate-cause TBI. Among children imaged by MRI or CT, abnormal cervical findings were found in 22.1%, including 31.3% of children with AHT, 7.1% of children with accidental TBI, and 0% of children with indeterminate-cause TBI. Children with more severe head injuries who underwent cervical imaging were more likely to have cervical injuries.

CONCLUSIONS

Abusive head trauma victims appear to be at increased risk of cervical injuries. Prospective studies are needed to define the risk of cervical injury in children with TBI concerning for AHT and to inform development of imaging guidelines.

Trends of traumatic spinal injury-related hospitalizations in Australian children over a 10-year period: a nationwide population-based cohort study

BACKGROUND CONTEXT

Despite its potential to cause serious and life-long disability or death, population-based data on traumatic spinal injury in pediatric populations is scarce.

PURPOSE

To quantify and describe the incidence and cost of hospitalizations for traumatic spinal injury among Australian children, and to examine the trend over a 10-year period.

STUDY DESIGN

Population-based retrospective cohort study.

PATIENT SAMPLE

Children aged ≤16 years who were hospitalized for traumatic spinal injury in Australia during 1 July 2002 to 30 June 2012.

OUTCOME MEASURES

Age-standardized hospital admission rates.

METHODS

This study used linked hospitalization and mortality data. Age-standardized hospitalization rates were calculated with 95% confidence intervals (CIs). Negative binomial regression was used to examine change in temporal trends in hospitalization rates.

RESULTS

There were 4,360 hospitalizations for pediatric traumatic spinal injury during the 10-year study period. Males and older children were more frequently hospitalized, and falls and road trauma accounted for almost three-quarters of hospitalizations. The average overall annual hospitalization rate was 9.43 (95% CI: 9.15-9.72) per 100,000 population, with an annual percent change of 1.2% (95% CI: -0.1% to 2.4%). There was an increase in the annual hospitalization rate for spinal dislocations, sprains, and strains (3.0% [95% CI: 0.8%-5.3%]) and among female children (1.7% [95% CI: 0.0%-3.4%]). The estimated total hospital treatment costs were AUD$43 million over the 10-year study period, with an estimated mean cost per child of AUD$9,867.

CONCLUSIONS

Pediatric traumatic spinal injury is associated with significant morbidity and mortality. The burden of hospitalized pediatric traumatic spinal injury in Australia is rising, in particular spinal dislocations, sprains, and strains among female children. Targeted prevention strategies are needed to reduce the burden of pediatric traumatic spinal injury. It is recommended that a coordinated national strategy for preventing childhood traumatic spinal injury is developed and implemented in Australia.

Morbidity after traumatic spinal injury in pediatric and adolescent sports-related trauma

OBJECTIVE

Sports injuries present a considerable risk of debilitating spinal injury. Here, the authors sought to profile the epidemiology and clinical risk of traumatic spinal injuries (TSIs) in pediatric sports injuries.

METHODS

The authors conducted a retrospective cohort analysis of pediatric patients who had experienced a sports-related TSI, including spinal fractures and spinal cord injuries, encoded in the National Trauma Data Bank in the period from 2011 to 2014.

RESULTS

Included in the analysis were 1723 cases of pediatric sports-related TSI, which represented 3.7% of all pediatric sports-related trauma. The majority of patients with TSI were male (81%), and the median age was 15 years (IQR 13-16 years). TSIs arose most often from cycling accidents (47%) and contact sports (28%). The most frequently fractured regions were the thoracic (30%) and cervical (27%) spine. Among patients with spinal cord involvement (SCI), the cervical spine was involved in 60% of cases.The average length of stay for TSIs was 2 days (IQR 1-5 days), and 32% of the patients required ICU-level care. Relative to other sports-related trauma, TSIs without SCI were associated with an increased adjusted mean length of stay by 1.8 days (95% CI 1.6-2.0 days), as well as the need for ICU-level care (adjusted odds ratio [aOR] 1.6, 95% CI 1.3-1.9). Also relative to other sports-related trauma, TSIs with SCI had an increased length of stay by 2.1 days (95% CI 1.8-2.6 days) and the need for ICU-level care (aOR 3.6, 95% CI 2.6-4.8).TSIs without SCI were associated with discharge to or with rehabilitative services (aOR 1.7, 95% CI 1.5-2.0), as were TSIs with SCI (aOR 4.0, 95% CI 3.2-4.9), both relative to other sports-related trauma. Among the patients with TSIs, predictors of the need for rehabilitation at discharge were having a laminectomy or fusion, concomitant lower-extremity injury, head injury, and thoracic injury. Although TSIs affected 4% of the study cohort, these injuries were present in 8% of patients discharged to or with rehabilitation services and in 17% of those who died in the hospital.

CONCLUSIONS

Traumatic sports-related spinal injuries cause significant morbidity in the pediatric population, especially if the spinal cord is involved. The majority of TSI cases arose from cycling and contact sports accidents, underscoring the need for improving education and safety in these activities.

[Pediatric spine trauma-Results of a German national multicenter study including 367 patients]

BACKGROUND

In general, pediatric spinal injuries are rare. No reliable data on the epidemiology of spinal injuries in pediatric patients in Germany are available. Especially in pediatric patients, for whom the medical history, clinical examination and the performance of imaging diagnostics are difficult to obtain, all available information on a spinal injury must be taken into account.

OBJECTIVE

The aim of this study was to provide epidemiological data for pediatric patients with spinal trauma in Germany in order to enhance future decision-making for the diagnostics and treatment of these patients.

MATERIAL AND METHODS

Within the framework of a national multicenter study, data were retrospectively obtained from 6 German spine centers for 7 years between January 2010 and December 2016. In addition to the demographic data, the clinical databases were screened for specific trauma mechanisms, level of injury as well as accompanying injuries. Furthermore, diagnostic imaging and the treatment selected were also analyzed.

RESULTS

A total of 367 children (female: male = 1:1.2) with a total of 610 spinal injuries were included in this study. The mean age was 12 years (±3.5 years). The most frequent trauma mechanisms were falls from <3 m and traffic accidents. The imaging diagnostics were only rarely carried out with the child under anesthesia. Younger children (0-9 years old) suffered more injuries to the cervical spine, whereas injuries to the thoracic and lumbar spine were more frequently found in older children (>10 years old). The children frequently showed accompanying injuries to the head and the extremities. Accompanying spinal injuries mostly occurred in adjacent regions and only rarely in other regions. Around 75% of the children were treated conservatively.

CONCLUSION

The results were different from the knowledge obtained from adult patients with spinal trauma and describe the special circumstances for pediatric patients with spinal trauma. Despite certain limitations these facts may help to enhance future decision-making for the diagnostics and treatment of these patients.

Neighborhood Poverty and Pediatric Intensive Care Use

BACKGROUND

Disparities in health service use have been described across a range of sociodemographic factors. Patterns of PICU use have not been thoroughly assessed.

METHODS

This was a population-level, retrospective analysis of admissions to the Cincinnati Children's Hospital Medical Center PICU between 2011 and 2016. Residential addresses of patients were geocoded and spatially joined to census tracts. Pediatric patients were eligible for inclusion if they resided within Hamilton County, Ohio. PICU admission and bed-day rates were calculated by using numerators of admissions and bed days, respectively, over a denominator of tract child population. Relationships between tract-level PICU use and child poverty were assessed by using Spearman's ρ and analysis of variance. Analyses were event based; children admitted multiple times were counted as discrete admissions.

RESULTS

There were 4071 included admissions involving 3129 unique children contributing a total of 12 297 PICU bed days. Child poverty was positively associated with PICU admission rates (r = 0.59; P < .001) and bed-day rates (r = 0.47; P < .001). When tracts were grouped into quintiles based on child poverty rates, the PICU bed-day rate ranged from 23.4 days per 1000 children in the lowest poverty quintile to 81.9 days in the highest poverty quintile (P < .001).

CONCLUSIONS

The association between poverty and poor health outcomes includes pediatric intensive care use. This association exists for children who grow up in poverty and around poverty. Future efforts should characterize the interplay between patient- and neighborhood-level risk factors and explore neighborhood-level interventions to improve child health.

Cervical trauma in children: Be aware of the risk of infection

Neck abscesses after a cervical trauma rarely occur, especially in children. Cervical abscesses are more generally complications of otolaryngological infections. Progression to severe complication or death may be rapid. We describe a case of a sternocleidomastoid muscle and retropharyngeal abscess that developed after a minor cervical trauma from being struck in the neck. The patient was surgically treated and received antibiotics, but returned with a recurrence of the cervical infection. We discuss the superinfection of the hematoma, cervical abscess management, and its treatment in children.

Epidemiology of traumatic spinal cord injury in childhood and adolescence in Galicia, Spain: report of the last 26-years

OBJECTIVE

To analyze the characteristics of traumatic spinal cord injury in children of Galicia (Spain).

DESIGN

Descriptive and retrospective study.

METHODS

Data extracted from the internal registry of the Spinal Cord Injury Unit and the patient's medical records, between March 1988 and December 2014. Inclusion criteria: patients aged ≤ 17 years with a traumatic spinal cord injury.

Outcome measures: Total patients, percentages, incidence, ASIA scale results and improvement.

RESULTS

A total of 68 patients were included. The incidence was 5.6 cases/1,000,000 inhabitants/year. The mean age was 14.4 years (median: 16). Only 25% were younger than 15. Male patients accounted for 73.5% of the total. The main cause were traffic accidents (60.3%; n = 41), being higher (77.8%) in children ≤ 10 years. Other etiologies included falls (19.1%), diving accidents (16.2%) and other causes (4.4%). Eleven patients (16.2%) had injuries classified as SCIWORA, 8 (72.7%) of them aged ≤ 10 years. The mean age of the SCIWORA group was 7.5 years versus 15.7 years in the non-SCIWORA group (P < 0.001). Half (50%) of these patients had a complete spinal cord injury and, of these, 64.6% were paraplegic.

CONCLUSIONS

Traumatic spinal cord injuries are rare in children, and most cases occur between 15 and 17 years. Unlike in adults, SCIs in children mostly involve the thoracic spine. Most patients aged ≤ 10 years have SCIWORA. The most common etiology continues to be traffic accidents, although sports accidents prevail among adolescent patients.

Spine trauma and spinal cord injury in Utah: a geographic cohort study utilizing the National Inpatient Sample

OBJECTIVE

The objective of this study was to investigate the effect of hospital type and patient transfer during the treatment of patients with vertebral fracture and/or spinal cord injury (SCI).

METHODS

The National Inpatient Sample (NIS) database was queried to identify patients treated in Utah from 2001 to 2011 for vertebral column fracture and/or SCI (ICD-9-CM codes 805, 806, and 952). Variables related to patient transfer into and out of the index hospital were evaluated in relation to patient disposition, hospital length of stay, mortality, and cost.

RESULTS

A total of 53,644 patients were seen (mean [± SEM] age 55.3 ± 0.1 years, 46.0% females, 90.2% white), of which 10,620 patients were transferred from another institution rather than directly admitted. Directly admitted (vs transferred) patients showed a greater likelihood of routine disposition (54.4% vs 26.0%) and a lower likelihood of skilled nursing facility disposition (28.2% vs 49.2%) (p < 0.0001). Directly admitted patients also had a significantly shorter length of stay (5.6 ± 6.7 vs 7.8 ± 9.5 days, p < 0.0001) and lower total charges ($26,882 ± $37,348 vs $42,965 ± $52,118, p < 0.0001). A multivariable analysis showed that major operative procedures (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.4-2.0, p < 0.0001) and SCI (HR 2.1, 95% CI 1.6-2.8, p < 0.0001) were associated with reduced survival whereas patient transfer was associated with better survival rates (HR 0.4, 95% CI 0.3-0.5, p < 0.0001). A multivariable analysis of cost showed that disposition (β = 0.1), length of stay (β = 0.6), and major operative procedure (β = 0.3) (p < 0.0001) affected cost the most.

CONCLUSIONS

Overall, transferred patients had lower mortality but greater likelihood for poor outcomes, longer length of stay, and higher cost compared with directly admitted patients. These results suggest some significant benefits to transferring patients with acute injury to facilities capable of providing appropriate treatment, but also support the need to further improve coordinated care of transferred patients, including surgical treatment and rehabilitation.

Pregnancy Outcomes in Women with Spinal Cord Injuries: A Population-Based Study

BACKGROUND

Pregnant women with congenital or acquired spinal cord injury face challenges due to compromised neurologic function and mobility, factors that may also affect fetal/infant health. Few studies have examined pregnancy course and longer-term outcomes in this population.

OBJECTIVE

To assess pregnancy outcomes among women with spinal cord injury, paralysis, or spina bifida using population-based data.

DESIGN

Retrospective cohort study.

SETTING

Washington state linked birth-hospital discharge records.

PARTICIPANTS

All women (N = 529) with spinal cord injury, paralysis, or spina bifida with singleton live birth deliveries 1987-2012, and a comparison group of women without disabilities (N = 5282).

METHODS

Diagnosis codes were screened to identify cases and a 10:1 random sample of comparison women. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated overall and separately for each condition using multivariable regression. Subsequent hospitalizations or death were identified via linkage to hospital discharge/death records for 2 years after delivery.

MAIN OUTCOME MEASUREMENTS

Pregnancy course (weight gain, gestational diabetes, preeclampsia, infection, venous thromboembolism), delivery/labor characteristics, infant characteristics (birthweight/size, gestational age), and longer-term outcomes (occurrence/reasons for maternal/infant rehospitalization, mortality).

RESULTS

Women with these spinal conditions had increased adjusted risks of prenatal urinary tract infection/pyelonephritis (RR 26.43, 95% CI 13.97-49.99), venous thromboembolism (RR 9.16, 95% CI 2.17-38.60), preterm rupture of membranes (RR 2.15, 95% CI 1.18-3.90), and cesarean delivery (RR 1.88, 95% CI 1.70-2.09). They had longer hospitalizations and increased rehospitalization (RR 1.54, 95% CI 1.28-1.87), including for postpartum depression (RR 8.15, 4.29-15.48) or injury (RR 13.05, 95% CI 6.60-25.81). Their infants were more often small for gestational age (RR 1.65, 95% CI 1.33-2.06), but had no increased risk of rehospitalization or death.

CONCLUSIONS

We observed no increased long-term morbidity among infants of women with these conditions. Possible increased maternal morbidities during the first postpartum years indicate areas for intervention.

Big Data Research in Pediatric Neurosurgery: Content, Statistical Output, and Bibliometric Analysis

BACKGROUND/AIMS

We sought to describe pediatric "big data" publications since 2000, their statistical output, and clinical implications.

METHODS

We searched 4 major North American neurosurgical journals for articles utilizing non-neurosurgery-specific databases for clinical pediatric neurosurgery research. Articles were analyzed for descriptive and statistical information. We analyzed effect sizes (ESs), confidence intervals (CIs), and p values for clinical relevance. A bibliometric analysis was performed using several key citation metrics.

RESULTS

We identified 74 articles, which constituted 1.7% of all pediatric articles (n = 4,436) published, with an exponential increase after 2013 (53/74, 72%). The Healthcare Cost and Utilization Project (HCUP) databases were most frequently utilized (n = 33); hydrocephalus (n = 19) was the most common study topic. The statistical output (n = 49 studies with 464 ESs, 456 CIs, and 389 p values) demonstrated that the majority of the ESs (253/464, 55%) were categorized as small; half or more of the CI spread (CIS) values and p values were high (274/456, 60%) and very strong (195/389, 50%), respectively. Associations with a combination of medium-to-large ESs (i.e., magnitude of difference), medium-to-high CISs (i.e., precision), and strong-to-very strong p values comprised only 20% (75/381) of the reported ESs. The total number of citations for the 74 articles was 1,115 (range per article, 0-129), with the median number of citations per article being 8.5. Four studies had > 50 citations, and 2 of them had > 100 citations. The calculated h-index was 16, h-core citations were 718, the e-index was 21.5, and the Google i10-index was 34.

CONCLUSIONS

There has been a dramatic increase in the use of "big data" in the pediatric neurosurgical literature. Reported associations that may, as a group, be of greatest interest to practitioners represented only 20% of the total output from these publications. Citations were weighted towards a few highly cited publications.

Epidemiology of spinal injury in childhood and adolescence in the United States: 1997-2012

OBJECTIVE There has been no successful study of trends in population-based incidences of pediatric spinal injury in the United States. The goal of the current study was to develop robust data to correct this deficiency in contemporary trauma epidemiology. METHODS Discharges coded for spinal injury were extracted from the Kids' Inpatient Database for 1997, 2000, 2003, 2006, 2009, and 2012 for patients younger than 18 years. Childhood was defined as ages 0 through 14 years and adolescence as ages 15, 16, and 17 years. Denominator population data were taken from the website of the US Census. Annual incidences were estimated for hospitalization for spinal injury, spinal cord injury (SCI), and hospital death with spinal injury. Mechanistic and anatomical patterns of injury were studied. RESULTS The annual population-based incidences of hospitalization for spinal injury, SCI, and death with spinal injury trended downward from 1997 to 2012 for children and adolescents in the United States. Rates of SCI and death fell faster than overall hospitalization rates, suggesting lower thresholds for admission or greater diagnostic sensitivity to minor injuries over time. The incidence of hospitalization for spinal injury was roughly 8 times greater for adolescents than for children, and the incidence of SCI was roughly 6 times greater. Motor vehicle crash predominated among mechanisms for both children and adolescents, but penetrating injuries and sport injuries were more commonly associated with SCI. Lumbosacral injuries predominated in both children and adolescents, but injuries of the cervical spine were more commonly associated with SCI. CONCLUSIONS Further research is needed to identify the cause or causes of the observed decline in injury rates. Epidemiological data can inform and support prevention efforts.

Treatment patterns of children with spine and spinal cord tumors: national outcomes and review of the literature

BACKGROUND

Tumors of the spine in children are rare, and further clinical description is necessary.

OBJECTIVE

This study investigated epidemiology, interventions, and outcomes of pediatric patients with spine and spinal cord tumors.

METHODS

The National Inpatient Sample and Kids' Inpatient Database were used for the study. Outcomes were studied, and bivariate significant trends were analyzed in a multivariate setting.

RESULTS

Analysis of 2870 patients between 2000 and 2009 found a median age of diagnosis of 11 years (Tables 1 and 2). Most were white (65.2%) and had private insurance (62.3%), and 46.8% of procedures were emergent operations. Treatment occurred at teaching (93.6%) and non-children's hospitals (81.1%). Overall mortality rate was 1.7%, non-routine discharges occurred at a rate 19.9%, complications at 21.1%, and average total charges were $66,087. A majority of patients (87.5%) had no intervention, and of those patients receiving treatment, 78.2% underwent surgery and 23.1% had radiotherapy. Treatment with surgery alone increased significantly over time (p < 0.0001). Odds ratio (OR) of mortality was significantly higher in 2006 (OR 3.5) and 2009 (OR 2.6) when compared to 2000. Complications (OR 7.9) and disease comorbidities (OR 1.5) were associated with significantly increased odds of mortality.

CONCLUSIONS

Hospital characteristics, length of stay, and charges remained relatively unchanged. In recent years, there has been a decreasing incidence of spine and spinal cord tumors in children. Notably, a higher mortality rate is evident over time in addition to an increase in the proportion of patients undergoing surgery. The high percentage of emergent operations suggests a weak recognition of spine tumors in children and should prompt a call for increased awareness of this cancer. In spite of these findings, lack of tumor type identification was a limitation to this study.

Pediatric thoracic SCIWORA after back bend during dance practice: a retrospective case series and analysis of trauma mechanisms

PURPOSE

The purpose of the study was to describe a unique type of low-energy traumatic pediatric thoracic spinal cord injury without radiographic abnormality (SCIWORA) after a back bend during dance practice and analyze the trauma mechanisms and treatment protocols.

METHODS

This was a retrospective case series from September 2007 to August 2016. The study was conducted at a tertiary medical center in Beijing, China (Xuanwu Hospital, China International Neuroscience Institute [China-INI], Capital Medical University). A total of 12 pediatric patients who had a clear traumatic history after back bend movements and had been diagnosed with thoracic SCIWORA were included. Clinical and imaging data were obtained for each patient. The follow-up data was analyzed. The traumatic mechanisms were investigated by analyzing the patients' medical history, spinal diffusion tensor imaging (DTI) and fiber tractography data.

RESULTS

Of the 12 patients, 11 (91.7%) were younger than 8 years old. The mean age of the patients was 6.6 years. All patients had a clear traumatic history of severe thoracic spinal cord injury after performing back bend movements. The mean follow-up time was 36.5 months. During the follow-up period, 1 patient (8.3%) recovered completely, and 11 patients (91.7%) had unfavorable prognoses, including 4 (33.3%) with incomplete recovery and 7 (58.3%) with no change. Two patients underwent spinal DTI, which showed rupture of the nerve fiber bundle in the section of the injury.

CONCLUSIONS

Back bend movements performed during dance practice may cause pediatric thoracic SCIWORA, particularly in children younger than 8 years old. We suggest that the mechanism of primary injury is the longitudinal distraction of the thoracic spine during back bend movements, which leads to violent distraction of the spinal cord and blunt injury of nerve axons, nerve cells, and small vessels. Spinal DTI may facilitate the diagnosis and prognostic evaluation of SCIWORA.

U.S. Estimates of Pediatric Spinal Cord Injury: Implications for Clinical Care and Research Planning

The aim of this study was to provide accurate estimates and characterizations of children with spinal cord injuries (SCIs) and for the subset that are appropriate for inclusion in clinical trials. We identified children <18 years of age with SCI International Classifications of Diseases, Ninth Revision, Clinical Modification Codes (ICD-9-CM codes) from the 2006, 2009, and 2012 Kids' Inpatient Database. We excluded those with late effects, transfers to other hospitals, unspecified injury levels, and hospital stays <48 h. We then used conventional rationale to identify children who were eligible for SCI clinical trials. Over 3 years, 2484 children had SCI ICD-9-CM codes; 1342 had coding consistent with true SCI and 706 satisfied clinical trial inclusion criteria, yielding national estimates of 2013 and 1062, respectively. Of children with clinical trial eligible SCI, injuries were more common in the cervical region (66.1%), males (65.5%), older children (51.1% were 16-17 years old), and the South (49.8%). The majority were treated at urban teaching hospitals (84.6%); however, only 20.3% were treated at pediatric-specific centers. Of the 445 sample hospitals treating children with SCI, 66.3% treated just 1 child in the 3-year period. Children eligible for SCI clinical trials represented less than one third of children with SCI ICD-9-CM codes. These children were regionally localized to the South, with few receiving treatment at pediatric-specific centers or centers that frequently care for children with SCI. These findings highlight the importance of carefully assessing the national distribution of children with SCI, so that resources are appropriately allocated to optimize clinical care and research outcomes.
