Background
• 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)
Anatomical reminder:
•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.
