Your radial nerve takes a winding path from your lower armpit to some of your fingers. It allows you to move muscles and feel skin sensations in certain parts of your upper arm, forearm, wrist and hand. Like other peripheral nerves in your body, your radial nerve can become damaged, causing symptoms like pain and muscle weakness.

Radial nerve is a terminal branch of the posterior cord and supplies the majority of the muscles in the posterior compartment of the arm/forearm/hand. Arises from posterior cord of the brachial plexus (C5-8, T1) Spirals posterolaterally around the humerus with the deep brachial artery in the...

In order to appreciate the radial nerve, we have to first understand the brachial plexus.

The "highways" merging into the brachial plexus are the 5th, 6th, 7th, and 8th cervical nerve roots,

Radial nerve entrapment is often thought to be a result of overuse, but it does occur due to other causes - such as direct trauma, fractures, compressive devices, or post-surgical changes. Learn more about how this injury typically presents, and understand the anatomical structures!
