A Case of Isthmic Spondylolisthesis Showing The Far-Out Syndrome

Abstract

We report a case of the Far-Out Syndrome that occurred in a female patient with isthemic spondylolisthesis and a 30% slip.
This syndrome was described as alar transverse process impingment of the L5 spinal nerve by Wiltse in 1984. The patient's chief complaint was bilateral leg pain and we were not able to visualize an abnormal lesion in the spinal canal with myelography, CTM or MRI. At surgery, it was necessary for L5 spinal nerve decompression to be carried out far enough laterally. L5 spinal root block is a important diagnostic tool in this syndrome.
