Because the joint is curved cheap duloxetine 40mg anxiety symptoms gerd, image guidance can be confusing and entry into the joint may be difficult buy cheap duloxetine 20mg on line anxiety young child, particularly when there is degen- erative disease. A small synovial recess along the superior and inferior margins of the joint will allow access without passing through the curved bone margins. As they rarely have prolonged therapeutic ben- efit, neurolysis of the joint nerve supply with chemical or radiofre- quency (RF) ablation is most often used for long-term pain control. These innervations arise from medial branches from both above and below each joint. The gray and white rami com- municantes connect the autonomic ganglia with the anterior division of the spinal nerves. This highlights the close proximity of the vertebral artery with the exiting spinal nerve. Spinal Nerves Entire books have been written about the anatomy of the spinal nerves. For the purpose of this text, we emphasize the elements that are of prime importance to the interventionist. In the spine, as in the brain, there are central (spinal cord) and pe- ripheral components (peripheral nerves) of the nervous system. The peripheral nerves are the components that are of major importance from the standpoint of potential therapy. The peripheral nerves are re- 12 Chapter 1 Spine Anatomy sponsible for somatosensory, somatomotor, and autonomic nerve func- tion. The spinal nerves exiting the neural foramina are composed of an anterior and a posterior division that coalesce into a single nerve in the neural foramina (Figure 1. The anterior division of the spinal nerve contains the motor fibers that originate in the cell bodies in the ante- rior horn of the spinal cord. Preganglionic autonomic fibers course in this anterior division as well and originate in the anterolateral horn of the spinal cord. These fibers branch to become the white rami com- municantes and synapse with postganglionic autonomic fibers in the autonomic ganglia along the spine to form the sympathetic trunk or extend to ganglia adjacent to end organs (celiac, mesenteric, etc. The sensory neurons (primary afferent) are found in the dorsal root of the spinal nerve. The dorsal root ganglia contain sensory cell bodies; the axons of these sensory nerves originate in specialized sensory structures (Golgi tendon organs, Ruffini endings from the joints, muscle spindles, pacinian corpuscles in fascial planes, etc. The sensory nerves separate within the cord and take characteristic routes to the brain, where they reach varying levels of consciousness based on their type. The various types of peripheral nerve are different not only because of their relative function but also because of physical size and con- duction velocity. General sensory fibers mediating touch and pro- prioception are intermediate in size, while pain and nocioceptive fibers are the smallest and have the slowest conduction velocity. To block these fibers an anesthetic must bind to (and block) three consecutive sodium channels (nodes of Ranvier). This means in clinical practice that a smaller amount of anesthetic is needed to block smaller fibers (pain) and that regular sensory and motor fibers are more resistant to anes- thetic block. This provides us with the ability to obtain differential blocking that allows pain to be blocked without the loss of motor func- tion (if appropriate amounts of anesthetic are chosen). The injectate (chosen for a specific effect) is introduced into or just lateral to the neural foramina. In the lumbar region, the foramina are larger than in the thoracic and cervical spine. Venous vascular structures are common in the lumbar foramina, but a much lower chance of an arterial injection exists here (Figure 1. In the cervical region, the vertebral artery lies along the anterior border of the foramina (Figure 1. Great care must be exercised when one is doing nerve blocks in this region, since direct injury (dissection) to the vertebral artery can occur and injection of anesthetics or steroids into the artery can create seizure or stroke, respectively.
