Although children < 10 years have the lowest rate of spinal cord injuries, such injuries are not rare. Most spinal injuries in children occur in the neck.
In children < 8 years, cervical spine injuries occur most commonly above C4 and are most commonly caused by motor vehicle crashes, falls, and child abuse. In children > 8 years, injuries at C5 to C8 are more common and are due to motor vehicle crashes and sports injuries, particularly gymnastics, diving, horseback riding, American football, and wrestling. Compared with adults, children have distinct anatomic features (eg, larger head size-to-body, elasticity of spinal ligament capsules) that predispose them to hypermobility of the spinal column without apparent bony injury.
Children with spinal cord injury may have transient symptoms such as paresthesias and weakness. Children may also have lancinating pains down the spine or extremities. In about 25% of affected children, onset of neurologic signs (such as partial neurologic deficits, complete paralysis) is delayed from 30 minutes to 4 days after injury, making immediate diagnosis difficult.
Spinal cord injury without evidence of radiologic abnormality (SCIWORA) is related to direct spinal cord traction, spinal cord impingement, spinal cord concussion, and vascular injury. This type of injury occurs almost exclusively in children and often occurs in the cervical spine. In spinal cord injury without evidence of radiologic abnormality, the patient has neurologic findings suggestive of spinal cord injury (eg, paresthesias, weakness) but normal anatomic alignment, and no bone abnormalities are seen on imaging studies (plain x-rays, CT, and/or MRI).

X-rays (cross-table lateral view, anteroposterior view, and open-mouth odontoid view)
Usually CT, particularly for bony or ligamentous injury
MRI to confirm injury site and level within the spinal cord
Spinal cord injury should be suspected in any child who has been in a motor vehicle crash, has fallen from a height ≥ 3 meters, or has had a submersion injury.
Spinal cord injury without evidence of radiologic abnormality (SCIWORA) is suspected in children who have even transient symptoms of neurologic dysfunction or lancinating pains down the spine or extremities and a mechanism of injury compatible with spinal cord injury. SCIWORA is a common phenomenon originally described in the 1980s, when there was a lack of MRI scanners capable of detecting the causative radiologic abnormalities. The term SCIWORA is less commonly used currently because MRI scanners are more readily available in hospitals in the US and can identify the causative radiologic abnormalities.
Depending on local imaging resource availability, imaging usually begins with x-rays, including cross-table lateral, anteroposterior, and open-mouth odontoid views. If fracture, dislocation, or subluxation is suspected based on x-ray findings or a very high-risk mechanism of injury, CT is usually done. MRI is usually done with any of the following:
Spinal cord injury is suspected based on x-ray or CT
Spinal cord injury is suggested by neurologic deficits on examination
Spinal cord injury is suggested by a history of even transient neurologic deficits
Maintenance of oxygenation and spinal cord perfusion
Surgical stabilization when appropriate
Long-term symptomatic care and rehabilitation
Children with a spinal injury should be transferred to a pediatric trauma center.

Surgical stabilization is less frequently indicated in children than adults with spinal cord injury; because spinal ligaments tend to be more lax in spinal cord injury without evidence of radiologic abnormality (SCIWORA) and bone fractures and complete ligamentous avulsion are absent, there may be no suitable target structure for stabilization. Another advantage of bracing is preservation of spinal mobility by avoidance of fusion surgery; fusion surgery increases risk of long-term spondylosis Cervical Spondylosis and Spondylotic Cervical Myelopathy Cervical spondylosis is osteoarthritis of the cervical spine causing stenosis of the canal and sometimes cervical myelopathy due to encroachment of bony osteoarthritic growths (osteophytes)... read more .

Thus, for children with spinal cord injury, centers in the US tend to avoid long-term use of corticosteroids, although some clinicians use short courses of high-dose steroids in the perioperative setting only.
Long-term treatments for pediatric SCIWORA are similar to treatments for adult spinal cord injury, with focus on both intensive physical rehabilitation of neurologically affected extremities and medical support for various common medical complications that occur with prolonged immobilization or weakness. Rehabilitation is multidisciplinary with involvement of physical therapists for gait training and lower extremity strengthening, occupational therapists for cervical cord injuries affecting upper extremity motor function that can result in contractures, and even speech therapists to assist with swallowing and secretion-clearance issues that affect high cervical injuries. Regular medical care and visits are necessary for severe spinal cord injury patients who are nonambulatory due to high risks of developing complications resulting from immobility.
Prognosis is directly related to initial neurologic function after injury. Children achieve better neurologic outcomes than adult patients with spinal cord injury ( 1, 2 Treatment references Although children 10 years have the lowest rate of spinal cord injuries, such injuries are not rare.
