Sciatic spinal deformity-lumbosacral list: an "unusual" presentation with review of the literature.

Sciatic spinal deformity or lumbosacral list has received little attention in the literature. The phenomenon was first described in 1881 by Remak, but it was not until 1942 that Duncan and Hoen made the association between disk herniation and lumbosacral list. Since that time, the literature concerning this topic has been sparse and the terminology inconsistent. A case of lumbosacral list associated with disk herniation is presented with documented resolution after surgery. The pathogenesis of the list is described with a comprehensive review of the literature.
