		There may be weakness of the wrist and finger extension muscles (with decreased ability to extend the arm at the elbow), a minor decreased ability to rotate the arm outward (supination), and difficulty lifting the wrist or fingers (extensor muscle weakness).
		Rarely, radial nerve dysfunction may be difficult to differentiate from a stroke in the brain.
		Nerve pain may be quite uncomfortable and may persist for a prolonged period of time.

	Radial nerve - Wikipedia, the free encyclopedia
		The radial nerve is a nerve in the human body, that supplies the arm, the forearm and the hand.
		The radial nerve and its branches supply the dorsal muscles, such as triceps brachii, the extrinsic extensors of the wrist and hands, and the cutaneous nerve supply to most of the back of the hand.
		The radial nerve divides into a deep branch, (which becomes the posterior interosseous nerve), and continues as the superficial branch which goes on to innervate the dorsum (back) of the hand.

	Radial Nerve
		The radial nerve arises from the posterior cord of the brachial plexus and travels around the posterior aspect of the humerus in the spiral groove with the profunda brachial artery.
		At operative exploration the posterior interosseous branch of the radial nerve is found to be transected, with a large neuromatous stump visible against the microsurgical background.
		The nerve is grafting from the proximal radial nerve posterior interosseous branch origin, under the bracioradialis, ECRL, ECRB muscle mass and to the distal posterior interosseus nerve.

		Radial nerve compression or injury may occur at any point along the anatomical course of the nerve and may have varied etiologies.
		Radial nerve palsy in the arm most commonly is caused by fracture of the humerus, especially in the middle third (Holstein-Lewis fracture) or at the junction of the middle and distal thirds.
		After emerging from the supinator, the nerve may be compressed before it bifurcates into medial and lateral branches, causing a complete paralysis of the digital extensors and dorsoradial deviation of the wrist secondary to paralysis of the extensor carpi ulnaris.

		Radial nerve palsy in the middle third of the arm is characterized by palsy or paralysis of all extensors of the wrist and digits, as well as the forearm supinators.
		Proximally, compression of the radial nerve at the lateral intermuscular septum must be suspected, especially in cases associated with humerus fractures.
		Severing or stretching the nerve is not uncommon while attempting to extricate the nerve in the middle and distal thirds of the arm from a bony spicule or healing callus.

		Radial tunnel syndrome happens when the radial nerve is squeezed where it passes through a tunnel near the elbow.
		The symptoms of radial tunnel syndrome are tenderness and pain on the outside of the elbow.
		In radial tunnel syndrome, the pain is centered about two inches further down the arm, over the spot where the radial nerve goes under the supinator muscle.

		In most cases, the radial nerve is damaged by trauma, repeated use of the nerve, or by the nerve being compressed by other structures.

		This is both because the radial innervated finger extensors contribute to abduction, and because the interossei are at a mechanical disadvantage in the flexed position.
		The anconeus, which is innervated by the same branch of the radial nerve that supplies the medial head of the triceps, shows significant evidence of denervation suggesting that this branch was injured after it gave innervation to the medial head of triceps but before it supplied anconeus.
		Nerve conduction studies to evaluate motor fibers of the radial nerve are more complicated than median and ulnar nerve studies.

		As it progresses along its course below the elbow joint, the radial nerve passes below the origin of the short radial extensor muscle, which has its origin from a fibrous band stretching from the epicondyle to the deep fascia of the volar aspect of the forearm.
		Although the superficial radial nerve may be exposed to direct trauma as a result of its superficial anatomical location, the usual trauma to which it is exposed results from an indirect source.
		The forceful contraction of the extensor group which enhances the tightening of the fibrous band at the muscular origin and/or forceful contraction of the supinator which narrows the slit through which the nerve penetrates are largely responsible for the resulting radial nerve entrapment phenomenon.

		Nerves are the "electrical wiring" system in all people that carry messages from the brain to the rest of the body.
		When nerve fibers are cut, the end of the fiber farthest from the brain dies, while the insulation stays healthy.
		If both the nerve and insulation have been cut and the nerve is not fixed, the growing nerve fibers may grow into a ball at the end of the cut, forming a nerve scar or neuroma.

		Although entrapment neuropathy of the radial nerve is fairly uncommon, entrapment syndromes themselves are well recognised (Ekstrom and Holden, 2002; Kato, Iwasaki, Minami, and Kamishima, 2003; Richter, Berbig, and Segantini, 2002).
