What are some common disorders of nerve?
Functionally, the peripheral nervous system starts in the vicinity of the spinal neural foramen where the sensory and motor fibers join. At its most proximal level, peripheral nervous system injury in the form of radiculopathy is caused by an injury to a nerve root due to structural disease (e.g., herniated disc or trauma), inflammation, or other causes. Plexus involvement by disease or injury may occur in the upper (brachial plexus) or lower extremity (lumbar or lumbosacral plexopathy).
Peripheral nerve conditions can be acquired or genetically mediated. Examples of genetic conditions include the hereditary sensory and motor neuropathies (e.g., Charcot–Marie–Tooth disease). Acquired peripheral neuropathies can stem from conditions such as diabetes, toxins (medications or other exogenous substances), inflammatory disorders, or metabolic disturbances.
Focal neural entrapment can be seen in carpal tunnel syndrome (CTS), cubital tunnel syndrome, or tarsal tunnel syndrome, and few others.
