A lumbar puncture or spinal tap is the insertion of a needle in between the bones, called vertebrae, that make up the lower portion of the spine (lumbar region) and into the fluid-filled space called the spinal canal. The purpose of this procedure is to withdraw some of the cerebral spinal fluid that surrounds the spinal cord for testing, or to administer a medication into the spinal canal.
