New Study on Nerve Block for Back Pain

To understand the importance of a new research paper, you should know that the vertebral bones of the spine have several important functions. They must protect the spinal cord, support the head and upper body, and enable egress of nerves that carry sensation and control muscles. They also need to remain flexible enough to allow freedom of movement. To accomplish all this, the vertebra has a complex yet marvelously esthetic structure that includes two wing-like bones called facets. They connect to the main vertebra via a small joint.
