Using Y. Mori's procedure (1981), the author performed an experimental study of myelography of the lumbar spine at L5-S1. The normal lumbo-sacral spine of a human cadaver was sectioned in a coronal plane passing the pedicles and devided it into the two parts. The anterior part was a vertebral body and the posterior part was a laminar portion. The intradural space was filled with a physiologic saline solution and about 3 ml of myodil as a contrast medium was introduced in it, then the dural sac was closed with a clamp at its top. A series of experiments were then performed by narrowing the space of the spinal canal under the following conditions.
