How deep is the radial nerve?

The deep branch of the radial nerve winds to the back of the forearm around the lateral side of the radius between the two planes of fibers of the Supinator, and is prolonged downward between the superficial and deep layers of muscles, to the middle of the forearm.

What are the symptoms of radial nerve damage?

A radial nerve injury usually causes symptoms in the back of your hand, near your thumb, and in your index and middle fingers.
