What is it?

A plexus is a network of intersecting nerve fibers that control both sensations and motor functions. The plexus is a combination all the nerve fibers that serve a specific body part and distributes nerve impulses to that body part.

Nerve root and plexus compressions.

Signs & symptoms

Symptoms include radiating pain, numbness, tingling, weakness, and shooting pain. Symptoms are the clue to where the nerve is compressed.


The diagnosis of a plexus disorder will include a comprehensive physical examination soon after the injury or symptoms appear because without innervation muscles will atrophy and impair the normal function of the muscles. Imaging tests will include X-rays, a CT scan, nerve conduction studies, and electrodiagnostic studies.

The diagnosis of a nerve root disorder will include a comprehensive physical examination, and MRI or CT scan. Treatment is focused on identifying and treating the cause of the pain.


Mild injuries to the plexus may improve with conservative measures. Surgery may be the only way to restore function when there are serious injuries. Treatment for nerve root disorders will involve treating the cause and may involve therapeutic injections, surgery, radiation therapy or chemotherapy.
