Inferior nerves collectively known as
Cauda equina
Damage to cauda equina
Legs affected
Forward translation of vertebra
Spondylolisthesis
*In spondylolisthesis, the body of a lower lumbar vetebra (usually L5) slips FORWARD on the body of the vertebra below (or upon the sacrum) and carries with it the whole of the upper portion of the vertebral column).
Stenoid narrowing symptoms
manifest:
Leg
Hangman’s fracture
Pedicles of the axis
*Severe extension injury of the neck such as might occur in an automobile accident or a fall, is the usual cause of Hangman’s fracture.
No IDV
