Abstract

– Abstract – Posterior epidural migration of sequestered lumbar disc fragments is an uncommon event. We present here an especially uncommon case involving a patient with paraparesis that was due to posterior migration of a ruptured disc in the adjacent segment after spinal fusion. The patient had a herniated lumbar disc in a diseased spinal junction with sequestered fragments that were located posterior to the thecal sac.
