Vascular complication involving the conus medullaris or cauda equina after vertebral manipulation for an L4-L5 disk herniation

Abstract

A case of injury to the cauda equina or conus medullaris after lumbar vertebral manipulation is reported. In contrast to all other previously reported cases, no migrated disk fragment was demonstrated. Similar to experience at the cervical spine, lumbar vertebral manipulation may carry a risk of vascular injury. The neurological manifestations in our patient were consistent with compression of the Desproges-Gotteron artery by a small L4-L5 disk herniation.
