A Dorsally Displaced Free Fragment of Lumbar Disc Herniation and Its Interesting Histologic Findings

Abstract
There are many1-3,5,6,8,9 reports related to the histologic findings of intervertebral disc herniation. Almost all of them examine the mechanism of occurrence of disc herniation in relation to disc degeneration. To our knowledge, there have been few reports8 describing the histologic findings of disc herniations that extruded to the spinal canal and formed free fragments. Recently, we resected microsurgically a lumbar disc herniation en bloc that extruded and migrated to the dorsal surface of the dura mater in the spinal canal at L2-3. Herein we report the cases and its histologic findings.
