Pediatric spinal trauma

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.

Update on Pediatric Spine Imaging

The spine is often difficult to evaluate clinically in children, increasing the importance of diagnostic imaging to detect a wide variety of spinal disorders ranging from congenital abnormalities to severe infections. Clinical history and physical examination can help determine whether imaging is needed and which imaging technique would be best. The most common cause for back pain, even in children, is muscular strain/spasm that does not require any imaging. However, red flags such as pain at age < 5 years, constant pain, night pain, radicular pain, pain lasting > 4 weeks, or an abnormal neurologic examination may require further investigation. Imaging can be of great value for diagnosis but must be interpreted along with the clinical history, physical examination, and laboratory findings to achieve an accurate diagnosis. We discuss imaging for the most common and/or important spine pathologies in children: congenital and developmental pathologies, trauma, infectious processes, inflammatory causes, and tumors.

Pediatric Spinal Cord Injury: A Review

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

Pediatric spinal injuries- current concepts

Spinal injuries in children contribute to the highest mortality and morbidity among all pediatric injuries. Fortunately, these injuries are a rare clinical entity but pose a difficulty in diagnosis due to challenges in neurological evaluation of a child and varied radiological presentation. Anatomical and biomechanical aspects of developing musculoskeletal system, relative plasticity of the pediatric spine make children vulnerable to spine injuries. Though motor vehicle collisions are common, children also suffer non-accidental trauma, falls and sports injuries. More chances of cervical spine involvement, higher susceptibility of spinal cord to tensile forces and associated multisystem injuries result in devastating consequences in children compared to adults. Injuries like SCIWORA, vertebral apophyseal injuries, birth-related spinal cord injuries are more specific injuries in pediatric age group. A vigilant clinical, neurological and radiological evaluation is mandatory in all children with suspected spinal injuries. Normal radiological features like ossification centers, pseudosubluxation and physiological vertebral wedging should be carefully noted as they could be misinterpreted as injuries. While CT scans help in better understanding of the fracture pattern, Magnetic Resonance Imaging in children is beneficial especially in detecting SCIWORA and other soft tissue injuries. Management principles of these pediatric spinal injuries are similar to adults. Literature evidences support conservative management in injuries like SCIWORA, unless there is an ongoing spinal cord compression. As in adults, the role of high dose methylprednisolone is still controversial in pediatric spinal cord injuries. Stable spinal injuries can be managed conservatively using orthosis or halo. Instrumentation by both anterior and posterior techniques has been described, but it is challenging due to smaller anatomy and poor implant purchase. In addition to pedicle screw instrumentation, wiring techniques are very beneficial especially in younger children.

Imaging of Abusive Head Trauma : A Radiologists' Perspective

Abusive head trauma (AHT) is the most common and serious form of child abuse and a leading cause of traumatic death in infants and young children. The biomechanics of head injuries include violent shaking, blunt impact, or a combination of both. Neuroimaging plays an important role in recognizing and distinguishing abusive injuries from lesions from accidental trauma or other causes, because clinical presentation and medical history are often nonspecific and ambiguous in this age group. Understanding common imaging features of AHT can increase recognition with high specificity for AHT. In this review, we discuss the biomechanics of AHT, imaging features of AHT, and other conditions that mimic AHT.

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).

The Pediatric Spine

The spine, a frequently investigated site in children, has a complex development in relation to both nervous and bone/cartilaginous structures and shows several particular features in children compared with adults. We report the main normal variants and pathologies of the pediatric spine, from the prenatal period to adolescence, focusing on a multimodality imaging approach.

Is spinal computed tomography necessary in pediatric trauma patients?

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

MRI Findings in Pediatric Abusive Head Trauma: A Review

Trauma is the most common cause of death and significant morbidity in childhood; abusive head trauma (AHT) is a prominent cause of significant morbidity and mortality in children younger than 2 years old. Correctly diagnosing AHT is challenging both clinically and radiologically. The primary diagnostic challenges are that the abused children are usually too young to provide an adequate history, perpetrators are unlikely to provide truthful account of trauma, and clinicians may be biased in their assessment of potentially abused children. The main radiological challenge is that there is no single imaging finding that is independently specific for or diagnostic of AHT. The radiological evaluation should be based on the multiplicity and severity of findings and an inconsistency with the provided mechanism of trauma. While the most common neuroimaging finding in AHT is subdural hemorrhage, other less well-known magnetic resonance imaging (MRI) findings such as the "lollipop sign" or "tadpole sign," parenchymal or cortical lacerations, subpial hemorrhage, cranio-cervical junction injuries including retroclival hematomas, as well as diffuse hypoxic brain injury have been identified and described in the recent literature. While AHT is ultimately a clinical diagnosis combining history, exam, and neuroimaging, familiarity with the typical as well as the less-well known MRI findings will improve recognition of AHT by radiologists.

Pediatric Spine Emergencies

Acute onset of neurological signs and symptoms referable to the spine including difficulty walking, bowel and bladder dysfunction, and paresthesias in the extremities may be manifestations of pediatric spine emergency. Trauma is the most common etiology for a pediatric spinal emergency. Because a history of trauma is often available, the role of imaging involves detection of spinal injuries. Other pathologies such as infection, inflammation, vascular, and neoplasms may lead to pediatric spinal emergencies that also require imaging for assistance in determining the etiology and appropriate management.

Diagnostic Approach to Pediatric Spine Disorders

Understanding the developmental features of the pediatric spine and spinal cord, including embryologic steps and subsequent growth of the osteocartilaginous spine and contents is necessary for interpretation of the pathologic events that may affect the pediatric spine. MR imaging plays a crucial role in the diagnostic evaluation of patients suspected of harboring spinal abnormalities, whereas computed tomography and ultrasonography play a more limited, complementary role. This article discusses the embryologic and developmental anatomy features of the spine and spinal cord, together with some technical points and pitfalls, and the most common indications for pediatric spinal MR imaging.

Back pain and scoliosis in children: When to image, what to consider

Back pain and scoliosis in children most commonly present as benign and self-limited entities. However, persistent back pain and/or progressive scoliosis should always be taken seriously in children. Dedicated diagnostic work-up should exclude etiologies that may result in significant morbidity. Clinical evaluation and management require a comprehensive history and physical and neurological examination. A correct imaging approach is important to define a clear diagnosis and should be reserved for children with persistent symptoms or concerning clinical and laboratory findings. This article reviews the role of different imaging techniques in the diagnostic approach to back pain and scoliosis, and offers a comprehensive review of the main imaging findings associated with common and uncommon causes of back pain and scoliosis in the pediatric population.
