The brachial plexus is a network of nerves that begin in the cervical/neck spinal cord and travel down the cervicoaxillary canal into the armpit. Forming in the area of the shoulder joint at the branch junction of the brachial plexus, the radial nerve extends down the arm, through the elbow joint, into the forearm, across the wrist, and tips of the fingers. The nerves are susceptible to injury that can cause abnormal function leading to unusual sensations and impaired muscle function.

One of the major nerves of the upper extremity.
Associated conditions to the radial nerve include lacerations, contusions, fractures, and palsies.
Nerve injuries often cause symptoms at different locations other than where the nerve damage is, complicating diagnosis. Determining the specific location of nerve damage is the first step in developing an appropriate treatment plan. Once the location has been identified, steps can be taken to prevent worsening damage to the nerve.
