The mechanism of ischemia in anteroposterior compression of the spinal cord.
Intraspinal balloons were used in monkeys to simulate lateral and posterior epidural masses. Posterior masses flatten the cord and occlude the central vasculature while lateral balloons have less effect on central cord perfusion. The significance of these findings in relation to spondylotic myelopathy is discussed.
