Abstract

This report is that of a study made on a number of human spinal cords by means of postmortem injection or by the benzidine stain. In a review of the literature, we found an interesting fact. Most of what has been written in the past forty years about the circulation of the human spinal cord, especially in anatomic and neurologic textbooks and handbooks, is either inaccurate or incomplete. A paper that gives an accurate and complete account is that by Kadyi,1 published in 1889, a truly masterful piece of work. He pointed out that only one fourth of the nerve roots in man are accompanied by segmental arteries which contribute significantly to the circulation of the spinal cord; on the average there are but eight. The largest is one in the upper lumbar portion of the cord, the arteria radicalis anterior magna, first described by Adamkiewicz 2 in 1882.
