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.
