 <title>Neural Foraminal Stenosis</title>
 <link>http://www.spine-health.com/glossary/n/neural-foraminal-stenosis</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;
&lt;p&gt;&lt;strong&gt;Neural foraminal stenosis&lt;/strong&gt; refers to compression of a spinal nerve as it leaves the spinal canal through the foramen (the opening between the vertebrae through which spinal nerve roots travel and exit to other parts of the body). &lt;a href=&quot;/information/neural-foraminal-stenosis&quot; title=&quot;Neural Foraminal Stenosis&quot;&gt;Neural foraminal stenosis&lt;/a&gt; may occur in either the lower back (lumbar spine) or the neck (cervical spine), and be caused by an osteophyte, a foraminal herniated disc, or collapse of the disc space.&lt;/p&gt;

 <title>Non-steroidal Anti-inflammataory Drugs (NSAIDs)</title>
 <link>http://www.spine-health.com/glossary/n/non-steroidal-anti-inflammataory-drugs-nsaids</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

Non-steroidal anti-inflammatory drugs is a class of analgesic medication that reduces pain, fever and inflammation. Since most episodes of back pain involve inflammation, NSAIDs such as ibuprofen and naproxen are often an effective treatment option.&lt;br/&gt;
&lt;p&gt;NSAIDs are cleared from the blood stream by the kidney; thus, precautions should be taken to avoid kidney damage and disease when NSAIDs are taken over an extended period. Side effects of NSAIDs include stomach ulcers and kidney and platelet dysfunction.&lt;/p&gt;&lt;p&gt;&lt;a href=&quot;http://www.spine-health.com/glossary/n/non-steroidal-anti-inflammataory-drugs-nsaids&quot;&gt;read more&lt;/a&gt;&lt;/p&gt;</description>

 <title>Non-Union</title>
 <link>http://www.spine-health.com/glossary/n/non-union</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;
A non-union refers to a failed spinal fusion (pseudoarthrosis) in which the segments of vertebral bone do not merge over the disc space. Spinal fusion can take up to two years for union to take place consummately and the rate of improvement depends on the health of the bones, recovery of nerve compression and conditioning of spinal muscles.&lt;br/&gt;

 <link>http://www.spine-health.com/glossary/n/non-invasive-procedure</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

A non-invasive procedure is a conservative treatment that does not require incision into the body or the removal of tissue. For the treatment of back pain, a combination of non-invasive procedures such as chiropractic manipulation, physical therapy and heat therapy are typically prescribed for several weeks.&lt;br/&gt;
&lt;p&gt;Noninvasive procedures are essential to pain management serving as an alternative to invasive surgery.&lt;/p&gt;&lt;p&gt;&lt;a href=&quot;http://www.spine-health.com/glossary/n/non-invasive-procedure&quot;&gt;read more&lt;/a&gt;&lt;/p&gt;</description>

 <link>http://www.spine-health.com/glossary/n/nerve</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;
A nerve is a cordlike structure composed of fibers that conduct sensory and motor impulses between the brain and spinal cord and other areas of the body. Nerve fibers can convey sensory signals to the brain from the skin or organs (afferent nerves) or conduct stimulatory signals from the brain to the muscles (efferent nerves).&lt;br/&gt;

 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;
The neural arch is the bony structure that arises from the back of the vertebral body and encloses the spinal cord. The vertebral arch is comprised of two pedicles, the short stout processes that extend from the sides of the vertebral body and two laminae, the broad flat plates that project from the pedicles and join in a triangle to form a hollow archway (the foramen).&lt;br/&gt;

 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

Nerve compression is a condition in which pressure is placed on the nerve causing pain, muscle weakness and potentially, nerve damage. A nerve can become compressed as it passes between tight regions of muscles and tissue or more commonly from spine conditions such as a &lt;a href=&quot;/conditions/herniated-disc/whats-a-herniated-disc-pinched-nerve-bulging-disc&quot; title=&quot;What&amp;#039;s a Herniated Disc, Pinched Nerve, Bulging Disc...?&quot;&gt;herniated disc&lt;/a&gt;, &lt;a href=&quot;/video/spondylolisthesis-symptoms-causes-and-treatment-options-video&quot; title=&quot;Spondylolisthesis Symptoms, Causes and Treatment Options Video&quot;&gt;spondylolisthesis&lt;span class=&quot;div-video-link&quot;&gt;&lt;/span&gt;&lt;/a&gt;, spinal stenosis, or arthritis in the spine.&lt;br/&gt;

 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

&lt;p&gt;Nerve block is a pain management technique involving the injection of an anesthetic into the area surrounding an affected nerve. The technique is used to treat nueropathic pain by interrupting pain signals to the brain. An injection of steroids, local anesthetics, or opoids can effectively produce short-term back pain relief.&lt;/p&gt;&lt;p&gt;&lt;a href=&quot;http://www.spine-health.com/glossary/n/nerve-block&quot;&gt;read more&lt;/a&gt;&lt;/p&gt;</description>

 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

Nerve root is the portion of the nerve that runs through the bony canal and exits at each vertebral segment of the spinal cord. The spinal cord can be divided into segments according to the nerve roots that branch off of it. Nerve roots along the cord consists of 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerves.&lt;br/&gt;

 <title>Narcotic</title>
 <link>http://www.spine-health.com/glossary/n/narcotic</link>
 <description>&lt;div class=&quot;doclabel&quot;&gt;Definition&lt;/div&gt;

A narcotic is a potent analgesic drug used to treat severe episodes of pain. Narcotics also known as opioids are derived from the opium poppy plant and produce the effect of dulling the senses and sometimes inducing sleep.&lt;br/&gt;
&lt;p&gt;Narcotic medications are highly effective in treating back pain for less than two weeks to treat post-operative pain or severe acute episodes of low back pain. After the initial two weeks, the body rapidly builds a natural tolerance to narcotic medications and they lose their effectiveness.&lt;/p&gt;&lt;p&gt;&lt;a href=&quot;http://www.spine-health.com/glossary/n/narcotic&quot;&gt;read more&lt;/a&gt;&lt;/p&gt;</description>
