5 lumbar
what is spondylosis?
unilateral or bilateral stress fx/defect of the pars interarticularis
which lumbar vertebrae is the largest?
why?

lumbar arteries (lumbar)
Main: Great anterior radicular artery (artery of Adamkiewicz)
what is the main artery of the spine?
Where does it supply?
What can happen if this is injured?
Great anterior radicular artery (artery of Adamkiewicz)
main blood supply to inferior 2/3 of spinal cord
(injury to this causes total paralysis of lower limbs)

(Hip bone (Ilium) + sacrum)
what portion of the spine supports the weight of the body?
L5-S1 responsible for carry entire weight of upper body
what is the brachial plexus injury?
how can this happen?
what can be the end result?
some or all communication between the spinal cord and the arm, wrist, & hand are cut off
accidents, trauma, or unrelated operations
amputation if unsuccessful (if nerve is not reconnected)
