Lumbar spondylolisthesis with isthmic defects
Abstract
The importance of spondylolisthesis, aside from the obvious malalignment and malformation of the affected vertebrae, rests mainly on the possibility and the extent of impairment of activity. In this discussion the authors are concerned mainly with the myelographic signs associated with spondylolisthesis in patients with isthmic changes.
