Radial nerve dysfunction
|
The radial nerve travels down the arm and supplies movement to the triceps muscle at the back of the upper arm. It also provides extension to the wrist, and helps in movement and sensation of the wrist and hand. The usual causes of nerve dysfunction are direct trauma, prolonged pressure on the nerve, and compression of the nerve from nearby body structures.
