Unlike volume models, surface models representing hollow, three-dimensional images have a small file size allowing them to be displayed, rotated, and modified in real time. Therefore, surface models of lumbosacral structures can be effectively used for interactive simulation of, virtual lumbar puncture, virtual surgery of herniated lumbar discs, and virtual epidural anesthesia. In this paper, we present surface models of extensive lumbosacral structures which can be used in medical simulation systems. One-hundred and thirty-eight chosen structures included the spinal cord, lumbar and sacral nerves, vertebrae, intervertebral discs, ligaments, muscles, arteries, and skin. The structures were outlined in the sectioned images from the Visible Korean.
