Pediatric Spine Trauma

A spinal cord injury is a potentially crippling injury that often results in severe and permanent disability. Spinal injury should be highly suspected in young patients with polytrauma. Pediatric spinal injuries are relatively uncommon compared to adults. However, their potential repercussions can be profound if not appropriately managed. One pivotal aspect is the remarkable flexibility and resilience of a child's spine, which can facilitate and complicate treatment approaches. Children's spines undergo significant growth and maturation, rendering them more susceptible to specific injury patterns, such as spinal cord injuries without radiographic abnormalities (SCIWORA). Furthermore, pediatric patients may exhibit atypical spinal cord injury signs and symptoms, necessitating a heightened level of clinical suspicion during assessment. Up to 5% of patients with a head injury may also have an associated spinal injury, thus the necessity for prompt intervention in such cases. Spinal cord injury involves various levels of the spine. The incidence rates are highest in the cervical region (55%), followed by the thoracic (15%), thoracolumbar junction (15%), and lumbosacral region (15%). Imaging serves as a cornerstone in diagnosing pediatric spine trauma, yet unique considerations must be taken into account to minimize radiation exposure, particularly in children. Sophisticated imaging technologies, eg, magnetic resonance imaging (MRI), are essential for thoroughly evaluating soft tissue injuries and providing invaluable information about the severity of the damage. Treatment strategies for pediatric spine trauma necessitate a meticulous approach focused on preserving spinal alignment, mitigating neurological deficits, and fostering optimal growth and development. Early implementation of immobilization techniques, such as cervical collars and spinal precautions, is crucial to prevent further injury during initial stabilization. Surgery may be warranted in cases of significant instability or neurological compromise. Rehabilitation is pivotal in optimizing functional recovery and quality of life for affected children. The spine consists of 5 distinct regions: cervical, thoracic, lumbar, sacral, and coccygeal. Each segment has unique characteristics that influence injury patterns and management strategies. The cervical spine comprises 7 vertebrae (C1-C7) and supports the head's weight while allowing for a wide range of motion. The first 2 vertebrae, the atlas (C1) and axis (C2), are specialized bones that facilitate head rotation. The pediatric cervical spine is particularly vulnerable to injury due to the relative disproportion between children's head size and neck muscle strength. The thoracic spine has 12 vertebrae (T1-T12), forming the vertebral column's middle segment. The thoracic vertebrae articulate with the ribs, providing structural support and protection for the thoracic organs. Fractures and dislocations of the thoracic spine are less common in pediatric patients but can occur in high-energy trauma. The lumbar spine comprises 5 vertebrae (L1-L5) and bears most of the body's weight. The lumbar vertebrae are larger and more robust than those in the cervical and thoracic regions, providing stability and support for activities such as walking and lifting. Injuries to the lumbar spine are relatively rare in pediatric patients but may occur in certain sports or motor vehicle accidents. The sacral region comprises 5 fused vertebrae (S1-S5), forming the sacrum, which articulates with the pelvis to transmit weight from the spine to the lower extremities. The coccyx, or tailbone, comprises 4 rudimentary vertebrae that provide attachment points for pelvic ligaments and muscles. Injuries to the sacral and coccygeal regions are uncommon in pediatric patients but can occur in direct lower back trauma or falls. The spinal cord, housed within the vertebral column, extends from the base of the brain to the lumbar spine and is divided into cervical, thoracic, lumbar, sacral, and coccygeal segments corresponding to the vertebral levels. The spinal cord is surrounded by protective meningeal layers, the dura, arachnoid, and pia mater, which help cushion and support the delicate neural tissue. The 3 most crucial nerve tracts in the spinal cord are the corticospinal (CST) and spinothalamic tracts (STT) and posterior or dorsal column (DC). The CST is a descending motor pathway located in the lateral (LCST) and ventral (VCST) spinal cord regions. Damage to this tract causes ipsilateral clinical findings, including muscle weakness, spasticity, increased deep tendon reflexes, and a Babinski sign. The STT is an ascending pathway that transmits pain and temperature sensations. The STT is located in the anterolateral portion of the cord. Damage to this tract results in loss of pain and temperature sensation on the body's opposite side. The DC are ascending sensory pathways that transmit vibration and proprioception. The DCs are located in the posterior cord region. Damage to one side of the DC causes ipsilateral loss of vibration and position sensation. Both the STT and DC transmit light touch. This sensation may be preserved after a spinal cord injury unless the STT and DC are simultaneously involved. Due to ongoing growth and development, pediatric patients exhibit unique vulnerabilities in their spinal anatomy. Cartilaginous growth plates (epiphyseal plates) at the long bones and vertebral bodies' margins render pediatric spines more susceptible to certain injury patterns, such as physeal fractures. Additionally, the ligamentous laxity and increased flexibility of pediatric spines may predispose children to specific injuries, such as SCIWORA, requiring a high suspicion index for diagnosis.
