Plexopathy is a disorder of the network of nerves in the brachial or lumbosacral plexus. Symptoms include pain, muscle weakness, and sensory deficits (numbness). There are two main types of plexopathy, based on the location of the symptoms: brachial plexopathy (affecting the arm) and lumbosacral plexopathy (affecting the leg).What is sacral plexopathy?
A sacral plexopathy is a disorder affecting the nerves of the sacral plexus, usually caused by trauma, nerve compression, vascular disease, or infection. Symptoms may include pain, loss of motor control, and sensory deficits. The sacral plexus is formed by:What is brachial and lumbosacral plexopathy?
Both brachial and lumbosacral plexopathy can also occur as a consequence of radiation therapy, sometimes after 30 or more years have passed, in conditions known as Radiation-induced Brachial Plexopathy (RIBP) and Radiation-induced Lumbosacral Plexopathy (RILP).What causes brachial plexopathy?
The disorder can also be secondary to compression or stretching of the brachial plexus (for example, during a baby's transit through the birth canal, in which case it may be referred to as Erb's Palsy or Klumpke's palsy ). Non-traumatic causes of brachial plexopathy include diabetes, malignancy, and infection.
