How long does the development of curvature and intervertebral discs take?

The development of spinal curvature and intervertebral discs begins during fetal development and continues into early adulthood. Curves in the spine, such as cervical and lumbar lordosis, typically form as a child begins to sit, crawl, and walk, usually stabilizing by the age of 18. Intervertebral discs develop alongside vertebral growth, with their structure and function maturing significantly during childhood and adolescence. Overall, this developmental process can span several years, often concluding by the late teens to early twenties.
