Spinal nerves are distributed approximately evenly along the spinal cord and spine. During a lumbar puncture, a needle is inserted between two lumbar bones (vertebrae) to remove a sample of cerebrospinal fluid. Each vertebra consists of a vertebral body in front and a vertebral arch at the back. Lumbar spinal stenosis is a progressive condition that comes on gradually. Your spinal cord is a bundle of nerves that runs through a tunnel formed by your vertebrae.

Current guidelines for the clinical management of acute spinal cord injury (SCI) recommend maintenance of mean arterial blood pressure (MAP) at 85 to 90 mmHg for the first seven days after SCI as a clinical option. As the tissue of spinal cord continues to enlarge, new longitudinal connections form between the transverse segmental arteries, most likely to facilitate distribution of blood within the vascular system. In the best of all situations, this risk occurs in a minimum of 20% of spine fusion surgeries. The series is often utilized in the context of trauma, postoperative imaging and for chronic conditions such as ankylosing spondylosis.
