|Ultrasound spinal cord of newborn and infants: normal radioanatomy and variant of normal.|
• Spinal ultrasound is the best examination, inexpensive, non-irradiating screening for these spinal abnormalities mostly dysraphism
• It allows to analyze the osteocartilaginous walls of the medullary canal and its contents: spinal cord, roots, cerebrospinal fluid (CSF)
•The spinal cord is located in the vertebral canal.
•It extends from the occipital foramen to the 1st or 2nd lumbar vertebrae.
•A small fibrous filament, derived from the meninges: terminale filum
extends from the end of the spinal cord to the coccyx.
•The spinal cord has 2 fusiform swellings:
- Cervical enlargement : C4-D1 (brachial plexus)
- Lumbar enlargement : D10-L1 (lumbosacral plexus)
•It is maintained in a relatively fixed position in the meninges by fibrous bridges (serrated ligaments).
•31 pairs of spinal nerves leave the spinal cord and exit the vertebral canal through foramen.
