The sacral nerves are the five pairs of spinal nerves which exit the sacrum at the lower end of the vertebral column. The roots of these nerves begin inside the vertebral column at the level of the L1 vertebra, where the cauda equina begins, and then descend into the sacrum.
The sacral canal is the caudal continuation of the lumbar spinal canal. The contents of the sacral canal include the meninges, the lower portion of the cauda equina (sacral and coccygeal nerve roots), the filum terminale, and fibrous and fatty tissue (Fig 3) (4). The epidural space terminates at the sacral hiatus.
