G54.0: Brachial plexus disorders

Nerves in a neuroplexus between your neck and your armpit are damaged.

The vertebrae form the vertebral canal on the rear of the spinal column. The spinal cord runs in the vertebral canal. Nerve fibers run from the brain into the body via the spinal cord and form nerves there. Every nerve is responsible for a particular part of the skin and for certain muscles. These nerves are important for instance in enabling us to feel and move our muscles.

At the side of the neck, nerves come out of the vertebral column and run on to the arm. As they go, branches come off the nerves to form a neuroplexus. When the neuroplexus is damaged, one may have various symptoms. For example, you may no longer be able to move certain muscles in your neck, shoulder or arm. You may also have less sensation in the neck, shoulder or arm areas.
