While pediatric cervical spine injuries are not extremely common, when they occur, the life-long debilitating consequences for the child, their family, and society are catastrophic. In order to mitigate these injuries to children, we must understand the mechanics of the child neck and the inputs which create these deleterious injuries. Automotive crashes represent a significant percentage of these injuries and often involve high rates of speed and inertial loading of the head and neck complex. Thus, in an effort to prevent child neck injuries, we set out to investigate the bending mechanics of the maturing cervical spine as a result of dynamic loading. Sixteen baboon cadaver specimens were utilized spanning the pediatric populace from 2 to 23-human equivalent years. The C5-C6 functional spinal units of these specimen were dissected free and rigidly fixed to a custom dynamic bending apparatus. This device applied dynamic angular displacements(mean of 27.6-rad/sec) to the superior vertebrae while minimizing the shear forces traveling through the specimen. The specimens were divided into a flexion and extension group for testing to failure and the loads, displacements, and accelerations of the event were recorded. The flexion and extension stiffness increased with maturation as did the failure moments for both flexion and extension. Further, these data were utilized to generate scaling from the child to adult for spinal mechanics. The raw data and these scaling values provide data for computational models and anthropomorphic test devices which may lead to a meaningful neck injury prevention scheme for children.
