History of spine surgery in the ancient and medieval worlds

There is a paucity of surviving texts from ancient and medieval times that can shed light on the early development of spine surgery. Nevertheless, the author reviews many of the available books and fragments and discusses early developments in the field of spine surgery from the point of view of physicians' personalities, general themes, and actual surgical practices. For purposes of an overview and to highlight changing trends in spine surgery, he divides the paper into four eras of medicine: 1) Egyptian and Babylonian; 2) Greek and early Byzantine; 3) Arabic; and 4) medieval.
