Unique features of pediatric spinal cord injury

The Thoracolumbar Injury Classification and Severity Score Appropriately Predicts Treatment in Children Aged 10 and Under

STUDY DESIGN

A retrospective cohort study.

OBJECTIVE

This study aims to assess the validity of the Thoracolumbar Injury Classification and Severity Score (TLICS) in patients ≤10 years old.

SUMMARY OF BACKGROUND DATA

TLICS is a validated measure developed to help facilitate clinical decision-making regarding thoracolumbar spinal trauma in adults. Studies examining the utility of TLICS in children skew toward older pediatric patients, where the spine's biomechanical properties are more similar to adults. Due to differences in a preadolescent spine compared with a more mature, adolescent spine, it is unclear if TLICS can be applied to younger patients.

METHODS

A single-center spine trauma registry was queried for patients ≤10 with an acute, traumatic thoracolumbar fracture treated at a level-1 pediatric trauma center between 2006 and 2020. Test characteristics and receiver-operator curve were used to evaluate TLICS based on TLICS <4 recommedning nonsurgical treatment and TLICS >4 recommending surgery.

RESULTS

We identified 94 patients with traumatic thoracolumbar fractures (surgical=20; nonsurgical=74). Despite TLICS-suggested operative management in 28 patients with TLICS >4, nine (32.1%) were initially treated nonoperatively. All patients who deviated from TLICS-suggested treatment had flexion-distraction injuries (FDI). Sensitivity, specificity, positive predictive value, and negative predictive value were 100%, 89.2%, 70.4%, and 100%, respectively. The receiver operating characteristic curve demonstrated a strong diagnostic ability of TLICS in predicting the need for surgery (area under the curve: 0.97, F1-score: 0.86).

CONCLUSION

TLICS score <4 showed strong validity and is highly specific in predicting non-operative management for patients ≤10 years old with thoracolumbar fractures. However, TLICS >4 has more limited specificity in indicating the necessity for surgical intervention, as many FDIs were successfully treated without surgery. Additional factors other than TLICS score may need to be considered for these more severe injuries to optimize management in this age group.

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.

Establishing an Australian pediatric spinal cord disorder register using consumer, health professional, and researcher perspectives

CONTEXT/OBJECTIVE

Pediatric spinal cord disorders (SCD) are rare, and epidemiological data available to support treatment are lacking. The implementation of a national data register tailored to this population would greatly assist clinicians and therapists in guiding clinical practice. This study gathered perspectives surrounding a prospective national pediatric spinal cord disorder register.

DESIGN

Survey and modified Delphi technique.

SETTING

Australia.

PARTICIPANTS

SCD consumers, health professionals, and researchers.

INTERVENTIONS

None.

OUTCOME MEASURES

None.

RESULTS

Purposive sampling recruited 6 consumers and 52 health professionals and researchers working in the field of SCD to participate. The consumer survey contained items including demographic information, general and pediatric-specific SCD health issues, and questions regarding activity and participation. The modified Delphi survey required health professionals and researchers to identify which "collection items" and "administrative features" should be included in a national SCD register for both clinical and research purposes. Seventeen essential and nine optional items, two outcome measures, data collection methods, consumer access, definition of "pediatric," and use of International Data Standards were included in the consensus for a minimum dataset.

CONCLUSION

This study developed a minimum dataset that could inform an Australian register for pediatric SCD. A register linking to an adult database is recommended to ensure coverage across the lifespan. While items for a minimum dataset have been recommended, this dataset is large. Review and refinement of this list are recommended to ensure the register is not overly time-consuming for practical use.

Exploring problems for school reintegration following spinal cord injury: Perspectives on the kindergarten through fifth-grade population

When a child acquires a spinal cord injury or disorder (SCI/D), they are faced with sudden onset of changes. Engagement in education, play, and leisure is immediately impacted. Using survey methodology, return to school for children in kindergarten through fifth grade following SCI/D was examined. Families at a large spinal cord rehabilitation center for the pediatric population on the East Coast of the United States were surveyed via email about their child's return to school to understand support and barriers a child faces when returning to school following SCI/D. Survey findings indicated that children face barriers related to school access, transportation, and educational support upon return to school. The primary barrier identified was access to educational support. Using survey findings, an in-clinic outpatient return-to-school recommendation form was developed to bridge the gap between medical model therapists and school staff that is specific to each child's needs. The curriculum is being developed to support families and therapists in preparing a child to return to school following SCI/D and to educate families to advocate for their child in the school setting. Future recommendations include further research regarding the placement of children in the school environment following SCI/D.

Durability of Improved Trunk Control Following Activity-Based Locomotor Training in Children With Acquired Spinal Cord Injuries

BACKGROUND

A recent study in pediatric spinal cord injury (SCI) demonstrated activity-based locomotor training (ABLT) improved trunk control, measured by the Segmental Assessment of Trunk Control (SATCo). It is not known whether improved trunk control is maintained and, if so, for how long.

OBJECTIVES

The purpose was to determine the durability of improvements in trunk control after ABLT is stopped. We hypothesized that SATCo scores at follow-up would not significantly regress (a) beyond the score measured at discharge and (b) to the initial SATCo pre-ABLT level.

METHODS

Patients were assessed pre ABLT, after completing an episode of care, and upon returning to the clinic 1 or more months without ABLT. Durability is a score change less than 3, which is the measurement error of the SATCo.

RESULTS

Twenty-eight children (10 females; 4 ± 2.5 years old) completed at least 40 sessions of ABLT and returned for the follow-up 8 ± 7 months (range, 1-38) after the episode of care. Trunk control improved 6 ± 3/20 points with ABLT (p < .0001). At the follow-up, average SATCo score decreased 2 ± 2/20 points, and the follow-up SATCo score was 4 ± 3 points higher than pre ABLT (p < .0001). There was no correlation between the change in SATCo scores and changes in age, weight, height or elapsed time between discharge and follow-up.

CONCLUSION

Improvements in trunk control due to ABLT were maintained, indicating ABLT is neurotherapeutic. Although not achieving complete recovery of trunk control, the immediate effects and sustained improvements provide support for a clinical shift to neurotherapeutic approaches and for continued research to achieve enhanced recovery.

Acute Myelopathy in Childhood

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

Scoliosis in paediatric onset spinal cord injuries

STUDY DESIGN

This is a retrospective longitudinal review.

OBJECTIVE

The purpose of this review was to identify predictors of developing clinical scoliosis and compare between traumatic and neurological aetiologies of SCI.

SETTING

This study was conducted at the Midland Centre of SCI.

METHOD

Case notes of all patients injured at an age up to 18 years and admitted between 1971 and 2013 were reviewed.

RESULTS

Sixty-nine individuals were identified, of which seven were excluded: three with pre-existing scoliosis and four with spina bifida. The remaining 62 (44 males, 18 females) had a median age at injury of 17 years (inter quartile range 13-17). Of these, 51 (82%) had traumatic and 11 (18%) had neurological injury. Most (42/51; 82%) of the children who had a traumatic injury were older than 13 years. The risk of developing scoliosis was lower for older patients (RR 0.68 per year, 95% CI 0.52-0.83) or following a traumatic injury (RR 0.36, 95% CI 0.20-0.66). A multivariable analysis based on age and trauma showed that only older age decreased the risk. A robust Receiver Operator Curve analysis suggested 14.6 years as the optimal threshold to predict development of scoliosis within 10 years (Area Under the Curve; AUC 0.83 (95% CI 0.73-0.93), sensitivity 70% (95% CI 50-89%), specificity 89% (95% CI 74-100%).

CONCLUSION

Our results suggest that age below 14.6 years was a predictor for scoliosis. Once adjustment is made for age, the incidence of scoliosis does not differ between traumatic and neurological aetiologies of paediatric SCI injury.

[Development and first application testing of a new protocol for preclinical spinal immobilization in children : Assessment of indications based on the E.M.S. IMMO Protocol Pediatric]

BACKGROUND

To protect the spine from secondary damage, spinal immobilization is a standard procedure in prehospital trauma management. Immobilization protocols aim to support emergency medicine personnel in quick decision making but predominantly focus on the adult spine; however, trauma mechanisms and injury patterns in adults differ from those in children and applying adult prehospital immobilization protocols to pediatric patients may be insufficient. Adequate protocols for children with spinal injuries are currently unavailable.

OBJECTIVE

The aim of this study was (i) to develop a protocol that supports decision making for prehospital spinal immobilization in pediatric trauma patients based on evidence from current scientific literature and (ii) to perform a first analysis of the quality of results if the protocol is used by emergency personnel.

MATERIAL AND METHODS

Based on a structured literature search a new immobilization protocol was developed. Analysis of the quality of results was performed by a questionnaire containing four case scenarios in order to assess correct decision making. The decision about spinal immobilization was made without and with the utilization of the protocol.

RESULTS

The E.M.S. IMMO Protocol Pediatric was developed based on the literature. The analysis of the quality of results was performed involving 39 emergency medicine providers. It could be shown that if the E.M.S. IMMO Protocol Pediatric was used, the correct type of immobilization was chosen more frequently. A total of 38 out of 39 participants evaluated the protocol as helpful.

CONCLUSION

The E.M.S. IMMO Protocol Pediatric provides decision-making support whether pediatric spine immobilization is indicated with respect to the cardiopulmonary status of the patient. In a first analysis, the E.M.S. IMMO Protocol Pediatric improves decision making by emergency medical care providers.

Traumatic spinal cord injuries: A retrospective cohort study of children seen in Western Australia between 1996 and 2016

PURPOSE

To describe the medical complexity of traumatic spinal cord injury (TSCI) in paediatric patients in Western Australia (WA). Secondly, to determine if Princess Margaret Hospital (PMH) for Children (the tertiary paediatric centre in WA where all TSCI patients are managed) is meeting the requirements of the Australasian Rehabilitation Outcomes Centre (AROC) paediatric rehabilitation minimum data set gathered on each patient.

METHODS

Retrospective cohort study of patients seen at PMH between 1996-2016. The AROC minimum dataset information data were gathered on each patient. Functional status and rehabilitation outcomes were assessed using Functional Independence Measure for Children (weeFIM), Canadian Occupational Performance Measure (COPM), and Goal Attainment Scaling (GAS). Patient complexity was captured by documenting the specialty teams involved, the number of readmissions, and the International Statistical Classification of Disease and Related Health Problems Z codes.

RESULTS

Data from 19 patients (13 males, age range 6 months-15 years; 6 females, age range 4 years-13 years) were available. There were 10 cervical TSCIs with a median length of stay of 213 days and 9 thoracic TSCIs with a median length of stay of 49 days. Patients had between zero and six comorbidities prior to their TSCI.

CONCLUSIONS

Children with medical complexity are responsive to rehabilitation but have a high burden of care, requiring multiple-specialty care and hospital re-admissions. AROC has set a minimum data set recommendation for the collection and examination of patient data. PMH meets the AROC guidelines for patient data collection and descriptive analyses.

Multidisciplinary team approach to traumatic spinal cord injuries: a single institution's quality improvement project

BACKGROUND

A stepwise multidisciplinary team (MDT) approach to the injured trauma patient has been reported to have an overall benefit, with reduction in mortality and improved morbidity. Based on clinical experience, we hypothesized that implementation of a dedicated Spinal Cord Injury Service (SCIS) would impact outcomes of a patient specific population on the trauma service.

METHODS

The trauma center registry was retrospectively queried, from January 2011 through December 2015, for patients presenting with a spinal cord injury. In 2013, a twice weekly rounding SCIS MDT was initiated. This new multidisciplinary service, the post-SCIS, was compared to the 2011-2012 pre-SCIS. The two groups were compared across patient demographics, mechanism of injury, surgical procedures, and disposition at discharge. The primary outcome was mortality. Secondary endpoints also included the incidence of complications, hospital length of stay (HLOS), ICU LOS, ventilator free days, and all hospital-acquired infectious complications. Logistic regression and Student's t test were used to analyze data.

RESULTS

Ninety-five patients were identified. Of these patients, 41 (43%) pre-SCIS and 54 (57%) post-SCIS patients were compared. Mean age was 46.9 years and 79% male. Overall, adjusted mortality rate between the two groups was significant with the implementation of the post-SCIS (p = 0.033). In comparison, the post-SCIS revealed shorter HLOS (23 vs 34.8 days, p = 0.004), increased ventilator free days (20.2 vs 63.3 days, p < 0.001), and less nosocomial infections (1.8 vs 22%, p = 0.002). While the post-SCIS mean ICU LOS was shorter (12 vs 17.9 days, p = 0.089), this relationship was not significant.

CONCLUSIONS

The application of an SCIS team in addition to the trauma service suggests that a structured coordinated approach can have an expected improvement in hospital outcomes and shorter length of stays. We believe that this clinical collaboration provides distinct specialist perspectives and, therefore, optimizes quality improvement. Level of evidence Epidemiologic study, level III.

Thoracolumbar Injury Classification and Severity Score in children: a reliability study

OBJECTIVE There are many classification systems for injuries of the thoracolumbar spine. The recent Thoracolumbar Injury Classification and Severity Score (TLICS) has been shown to be a reliable tool for adult patients. The aim of this study was to assess the reliability of the TLICS system in pediatric patients. The validity of the TLICS system is assessed in a companion paper. METHODS The medical records of pediatric patients with acute, traumatic thoracolumbar fractures at a single Level 1 trauma center were retrospectively reviewed. A TLICS was calculated for each patient using CT and MRI, along with the neurological examination recorded in the patient's medical record. TLICSs were compared with the type of treatment received. Five raters scored all patients separately to assess interrater reliability. RESULTS TLICS calculations were completed for 81 patients. The mean patient age was 10.9 years. Girls represented 51.8% of the study population, and 80% of the study patients were white. The most common mechanisms of injury were motor vehicle accidents (60.5%), falls (17.3%), and all-terrain vehicle accidents (8.6%). The mean TLICS was 3.7 ± 2.8. Surgery was the treatment of choice for 33.3% of patients. The agreement between the TLICS-suggested treatment and the actual treatment received was statistically significant (p < 0.0001). The interrater reliability of the TLICS system ranged from moderate to very good, with a Fleiss' generalized kappa (κ) value of 0.69 for the TLICS treatment suggestion among all patients; however, interrater reliability decreased when MRI was used to contribute to the TLICS. The κ value decreased from 0.73 to 0.57 for patients with CT only vs patients with CT/MRI or MRI only, respectively (p < 0.0001). Furthermore, the agreement between suggested treatment and actual treatment was worse when MRI was used as part of injury assessment. CONCLUSIONS The TLICS system demonstrates good interrater reliability among physicians assessing thoracolumbar fracture treatment in pediatric patients. Physicians should be cautious when using MRI to aid in the surgical decision-making process.

Respiratory functional and motor control deficits in children with spinal cord injury

Children with spinal cord injury (SCI) are at high risk for developing complications due to respiratory motor control deficits. However, underlying mechanisms of these abnormalities with respect to age, development, and injury characteristics are unclear. To evaluate the effect of SCI and age on respiratory motor control in children with SCI, we compared pulmonary function and respiratory motor control outcome measures in healthy typically developing (TD) children to age-matched children with chronic SCI. We hypothesized that the deficits in respiratory functional performance in children with SCI are due to the abnormal and age-dependent respiratory muscle activation patterns. Fourteen TD (age 7±2 yrs., Mean±SD) and twelve children with SCI (age 6±1 yrs.) were evaluated by assessing Forced Vital Capacity (FVC); Forced Expiratory Volume in 1sec (FEV₁); and respiratory electromyographic activity during maximum inspiratory and maximum expiratory airway pressure measurements (PI_max and PE_max). The results indicate a significant reduction (p<.01) of FVC, FEV₁ and PE_max values in children with SCI compared to TD controls. During PE_max assessment, children with SCI produced significantly decreased (p<.01) activation of respiratory muscles below the neurological level of injury (rectus abdominous and external oblique muscles). In addition, children with SCI had significantly increased (p<.05) compensatory muscle activation above the level of injury (upper trapezius muscle). In the TD group, age, height, and weight significantly (p<.05) contributed towards increase in FVC and FEV₁. In children with SCI, only age was significantly (p<.05) correlated with FVC and FEV₁ values. These findings indicate the degree of SCI-induced respiratory functional and motor control deficits in children are age-dependent.

Development and Initial Validation of the Pediatric Neuromuscular Recovery Scale

PURPOSE

The Neuromuscular Recovery Scale (NRS) was developed to assess the capacity of adults' post-spinal cord injury (SCI) to perform functional tasks without compensation. Application of the NRS to children has been challenging. The purpose of this study was to develop and complete the initial validation of a pediatric version of the NRS.

METHODS

First, the investigative team developed a draft Pediatric NRS. Next, a Delphi method was used to amend the draft by 12 pediatric experts. Finally, the revised Pediatric NRS was field-tested on a sample of children with SCI (n = 5) and without (n = 7).

RESULTS

After the Delphi process and field testing, the Pediatric NRS consists of 13 items scored on a 12-point scale. All items, except 1, achieved 80% agreement by experts.

CONCLUSIONS

This is the first step in development and validation of a pediatric SCI scale that evaluates neuromuscular capacity, in the context of pediatric function, without compensation.

Pediatric Spinal Cord Injury: Recognition of Injury and Initial Resuscitation, in Hospital Management, and Coordination of Care

Spinal cord injury is uncommon in the pediatric population with a lifelong impact for the patient and family. Knowledge of spine embryology, mechanisms of injury that lead to specific injuries, appropriate utilization of radiographic imaging based on suspected injury, prehospital and hospital management of various spinal cord injuries is essential for providers attending to traumatically injured patients. In addition to patients who present with soft tissue and bony injuries diagnosed with clinical examination and confirmed with computed tomography or magnetic resonance imaging, it is important to note that the pediatric population is at a higher risk for spinal cord injury without radiographic abnormality than the adult population. Patients who survive the acute phase of injury face long-term rehabilitation and have an increased risk of depression and mortality. Understanding the long-term sequelae of spinal cord injuries is also an essential management component of traumatically injured children. A program that provides long-term rehabilitation, psychosocial and spiritual support, and adaptive environmental supports gives patients and their families the best opportunity for long-term recovery. A review of the current literature on the diagnosis, management, and follow-up of pediatric spinal cord injury is presented.

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 fractures with associated spinal cord injury in children and adolescents: epidemiology, costs, and in-hospital mortality rates in 4418 patients

BACKGROUND

Cervical spine fractures with spinal cord injury (CFSCI) can be devastating. We describe the epidemiology of children and adolescents with CFSCI.

METHODS

Using the Nationwide Inpatient Sample (NIS) database, we identified 4418 patients (≤18 years old) who had CFSCI from 2000 through 2010. Outcomes of interest were patient characteristics (age, sex), injury characteristics [fracture location, spinal cord injury (SCI) pattern], economic variables (duration of hospital stay, total hospital charges), and mortality.

RESULTS

Upper cervical fractures (UCFs) occurred half as often (31.4 %) as lower cervical fractures (LCFs; 68.8 %). Among patients <8 years old, 73.6 % had UCFs; among patients ≥8 years old, 72.3 % had LCFs. Overall, 68.7 % had incomplete SCI, 22.4 % had complete SCI, 6.6 % had central cord syndrome, and 2.3 % had anterior cord syndrome. Patients with complete SCI had the longest hospital stays and highest hospital charges. The overall in-hospital mortality rate was 7.3 %, with a sixfold higher rate in patients <8 (30.6 %) vs. those ≥8 (5.1 %) years old (p < 0.001). There was a threefold higher mortality rate in patients with upper (13.5 %) vs. lower (4.3 %) cervical fractures (p < 0.001). Patients with complete SCI had a 1.85-fold higher mortality rate than patients with other cord syndromes (p < 0.001).

CONCLUSIONS

Patients <8 years old were more likely than older patients to sustain UCFs. Patients with UCFs had a significantly higher mortality rate than those with LCFs. Patients with complete SCI had the longest duration of hospital stay and highest hospital charges and in-hospital mortality rate.

Neuromuscular scoliosis

The purpose of this focused review is to provide an overview of neuromuscular scoliosis from the perspective of the rehabilitation physician. Scoliosis is a common consequence of neuromuscular diseases, including central nervous system disorders such as cerebral palsy and spinal cord injury; motor neuron disorders, for example, spinal muscular atrophy; muscle fiber disorders, for example, Duchenne muscular dystrophy; multifactorial disorders, for example, spina bifida; and many other neuropathic and myopathic conditions. Unlike adolescent idiopathic scoliosis, which is the most common form of spinal deformity, neuromuscular scoliosis is more severe and more progressive, and is associated with more morbidity. Factors that contribute to this spinal deformity include asymmetric paraplegia, imbalance of mechanical forces, intraspinal and congenital anomalies of the spine, altered sensory feedback, and abnormal posture via central pathways. Spinal deformity combined with limitations due to an underlying neuromuscular condition lead to significant physiologic impairments that affect limb movement, cardiopulmonary function, gait, standing, sitting, balance, trunk stability, bimanual activities, activities of daily living, and pain, as well as concerns with self-image and social interactions. Evaluation and management of this population requires understanding of disease progression, pulmonary status, functional limitations, indications for conservative and surgical interventions, and social considerations.

The effectiveness of scoliosis screening programs: methods for systematic review and expert panel recommendations formulation

BACKGROUND

Literature on scoliosis screening is vast, however because of the observational nature of available data and methodological flaws, data interpretation is often complex, leading to incomplete and sometimes, somewhat misleading conclusions. The need to propose a set of methods for critical appraisal of the literature about scoliosis screening, a comprehensive summary and rating of the available evidence appeared essential.

METHODS

To address these gaps, the study aims were: i) To propose a framework for the assessment of published studies on scoliosis screening effectiveness; ii) To suggest specific questions to be answered on screening effectiveness instead of trying to reach a global position for or against the programs; iii) To contextualize the knowledge through expert panel consultation and meaningful recommendations. The general methodological approach proceeds through the following steps: Elaboration of the conceptual framework; Formulation of the review questions; Identification of the criteria for the review; Selection of the studies; Critical assessment of the studies; Results synthesis; Formulation and grading of recommendations in response to the questions. This plan follows at best GRADE Group (Grades of Recommendation, Assessment, Development and Evaluation) requirements for systematic reviews, assessing quality of evidence and grading the strength of recommendations.

CONCLUSIONS

In this article, the methods developed in support of this work are presented since they may be of some interest for similar reviews in scoliosis and orthopaedic fields.

Neuromuscular scoliosis in children with spinal cord injury

BACKGROUND

The prevalence of neuromuscular scoliosis in children with spinal cord injury (SCI) is high. Published reports suggest that age at time of injury is the most important determinant. No studies have evaluated neurological characteristics using standardized methods to determine if they are strong predictors of scoliosis.

OBJECTIVE

To test the hypothesis that neurological level, motor score, and injury severity are strong predictors of neuromuscular scoliosis.

METHODS

Two hundred seventeen children were evaluated using the testing guidelines of the International Standards for Neurological Classification of Spinal Cord Injury. Cobb angles were calculated from plain radiographs as a measure of scoliosis. Multivariate analysis with statistical selection was used to determine predictors of worst Cobb angle and spinal fusion. The odds of having a spine fusion for subjects with at least 2-year follow-up and injured prior to (n=16) and after (n=91) 12 years of age were calculated.

RESULTS

The hypothesis was not supported. Although there was a very high prevalence (100%) of scoliosis in the study sample, age at time of injury was the only predictor of worst curve (P < .0001) and spine fusion (P < .007). The calculated odds ratio demonstrated that children injured <12 years were 3.7 times more likely to have a spine fusion (95% CI, 0.31-44.64).

CONCLUSION

There is a very high prevalence of neuromuscular scoliosis in pediatric SCI. Neurological level, motor level, and severity of injury are not strong predictors. Age is the only predictor of worst curve and spine fusion.

Injuries of the Upper Cervical Spinal Column are Markers of Severe Forces in the First Two Years of Life

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

[Cardiac arrest in a 10-month-old boy with spinal cord injury]

A 10-month-old boy with a previous upper spinal cord injury was admitted to hospital with acute respiratory and circulatory distress. Shortly after admission the boy had severe bradycardia leading to asystolia and pulseless electrical activity. He was successfully resuscitated, and the investigation that followed excluded infection, congenital heart defect, arrhythmia and cerebral haemorrhage. Over the following days the patient had several episodes of isolated bradycardia and combined bradycardia and hypotension. It was concluded that the patient suffered from autonomic dysreflexia, triggered by a distended urinary bladder. He was treated with intermittent catheterization and a permanent pacemaker, and after 12 months there have not been any symptomatic episodes or registered arrhythmias. Autonomic dysreflexia is a common and well known complication of spinal cord injury above Th6, but the literature on paediatric patients is scarce. Our case report presents an infant with an atypical and severe episode of autonomic dysreflexia. Patients with spinal cord injury, their caregivers and health-care personal should be aware of this complication of spinal cord injury, in order to prevent and treat autonomic dysreflexia properly and avoid potentially fatal episodes.

Spinal injuries in children

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

Cervical spine injury in the young child

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

Age, sex, and socio-economic status affect the incidence of pediatric spinal cord injury: an eleven-year national cohort study

BACKGROUND

Few studies focus on pediatric spinal cord injury (SCI) and there is little information regarding the cause, anatomic level, and high risk population of SCI in children. This study aims to investigate the incidence and risk factors of pediatric SCI.

METHODS

A nationwide cohort of 8.7 million children aged<18 years in an 11-year period was analyzed for causes, age at injury, anatomic sites, disability, and familial socio-economic factors. Incidence rates and Cox regression analysis were conducted.

RESULTS

A total of 4949 SCI patients were analyzed. The incidence rates of cervical, thoracic, lumbar, and other SCI were 4.06, 0.34, 0.75, and 0.85 per 100,000 person-years, respectively. The proportional composition of gender, age, and socio-economic status of SCI patients were significantly different than those of non-SCI patients (all p<0.001). Male children were significantly more likely to have SCI than females in both the cervical and the other SCI groups [Incidence rate ratio (IRR) = 2.03 and 1.52; both p<0.001]. Young adults and teenagers were also significantly more likely to have SCI than pre-school age children in the cervical SCI (IRR = 28.55 and 10.50, both p<0.001) and other SCI groups (IRR = 18.8 and 7.47, both p<0.001). Children in families of lower socio-economic status were also significantly more likely to have SCI (p<0.05).

CONCLUSIONS

In the pediatric population, the overall SCI incidence rate is 5.99 per 100,000 person-years, with traumatic cervical SCI accounting for the majority. The incidence rate increases abruptly in male teenagers. Gender, age, and socio-economic status are independent risk factors that should be considered.
