Imaging of pediatric cervical spine trauma

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.

Pediatric cervical spine clearance after blunt trauma and negative CT: What is the role of MRI?

BACKGROUND AND PURPOSE

The cervical spine in children has marked anatomical and biomechanical differences compared to adults, leading to significantly different patterns and incidence of spinal injury, and consequently to different X-ray and computed tomography (CT) imaging recommendations. Magnetic resonance imaging (MRI) has been validated to clear cervical spine trauma in adults, but not in pediatric patients. We hypothesized that MRI findings have a low probability to change management in children with spine trauma and negative CT findings.

MATERIALS AND METHODS

We reviewed records for admitted pediatric patients due to blunt trauma from January 2011 to May 2021, and identified 212 patients who underwent MRI within 3 days of a negative CT. Two neuroradiologists independently reviewed all CT and MRI images for the following categories: fracture, subluxation, spinal canal compromise, ligamentous injury, spinal canal hemorrhage, cord contusion and soft tissue hemorrhage. We identified follow-up MRI examinations as negative or positive for the above categories, and calculated the prevalence of each category as a percentage of cases with negative CT. We also evaluated whether negative and positive MRI groups differed significantly with respect to age and sex of the patients.

RESULTS AND CONCLUSIONS

In our study of 212 children with cervical spine trauma and a negative CT, most follow-up MRI scans were found to be negative (79.9 %). Positive MRI findings consisted mainly of ligamentous sprain without disruption (15.1 %). Ligamentous disruption and epidural or soft tissue hemorrhage were found in 4.5 %, and focal cord contusion in 0.5 %. There was no statically significant difference between negative and positive MRI groups with respect to age (P = 0.45) and sex (P = 0.52).

CONCLUSION

In our patient group with a negative CT, MRI did not significantly impact management nor contribute to cervical spine clearance in children.

Relationship of cervical soft tissue injury and surgical predication following pediatric cervical spinal trauma and its sequelae on long-term neurologic outcome

Within the sample of 181 patients with cervical CT, CT identified unstable injury with a sensitivity of 100% and specificity of 95%. CT identified operable injury at the CCJ with 86% sensitivity and 91% specificity. CT was considered the gold standard for identification of fractures. Together, the presence of CT imaging suggestive of unstable injury or persistent neurologic complaint had a 100% sensitivity and 81% specificity. Finally, across all patients MRI had 100% sensitivity and 89% specificity for detection of unstable injury requiring surgery.

Diagnostic Excellence in Pediatric Spine Imaging: Using Contextualized Imaging Protocols

Contextual design and selection of MRI protocols is critical for making an accurate diagnosis given the wide variety of clinical indications for spine imaging in children. Here, we describe our pediatric spine imaging protocols in detail, tailored to specific clinical questions.

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.

Cervical Interspinous Ligament Sprain in a 6-Year-Old Boy

Paediatric cervical spine trauma, though rare, is difficult to detect as the injuries are often soft-tissue injuries and thus not visible using conventional radiography. A 6-and-a-half-year-old child presented with neck pain following a fall. A thorough radiological workup over several days demonstrated soft-tissue injuries, undetected by initial cervical X-rays, requiring MRI to definitively prove. The patient recovered with conservative treatment. Teaching Point: Paediatric cervical spine injuries often present with soft tissue injuries, which can missed on X-rays and require further imaging to detect.
