Answer

Postnatal spinal growth also must be understood and appreciated. Dimeglio showed that the majority of spinal canal diameter (about 90%) has been achieved by age 5 years; by age 10 years, approximately 80% of sitting height has also been achieved. [23, 24] During adolescence, radiographic evidence of ossification of the growth cartilage of the vertebral bodies occurs. Prior to this, these completely cartilaginous growth plates remained nestled between their respective vertebral bodies and intervertebral disks.
