Radial neuropathy occurs when there is damage to the radial nerve, which travels down the arm and controls: Movement of the triceps muscle at the back of the upper arm. Ability to bend the wrist and fingers backward. Movement and sensation of the wrist and hand.
The radial tunnel is an area below your elbow. Your radial nerve enters this tunnel of muscle and bone and then travels down to your wrist. When your radial nerve is pinched anywhere in your arm, it can cause pain and weakness.
[1][2] It is also commonly known as Wartenburg syndrome and superficial radial nerve palsy. The superficial radial nerve is purely sensory and does not have any motor component. The condition presents with symptoms such as pain and burning located on the dorsal and radial side of the hand.
Radial tunnel syndrome occurs when the nerve is pinched or compressed as it enters the radial tunnel. This creates unwanted pressure on your radial nerve, often causing nagging pain.
The radial nerve helps you move your elbow, wrist, hand and fingers. It runs down the back of the arm from the armpit to the hand. The radial nerve is part of the peripheral nervous system.
The radial nerve starts at the side of the neck, where the individual nerve roots leave the spine. The nerve passes down the back of the upper arm. It then spirals outward and crosses the outside (the lateral part) of the elbow before it winds its way down the forearm and hand.
Course. The radial nerve lies posterior to the axillary artery in the axilla and enters the posterior compartment of the arm under teres major muscle via the triangular interval. In the posterior compartment of the arm, it winds its way around the spiral groove of the humerus, accompanying profunda brachii artery.
The superficial branch of the radial nerve provides sensory innervation to much of the back of the hand, including the web of skin between the thumb and index finger.

Compression or entrapment can occur at any location within the course of the nerve distribution, but the most frequent location of entrapment occurs in the proximal forearm. This most common location is typically in proximity to the supinator and often will involve the posterior interosseous nerve branch.
The most common causes of radial nerve injury are breaking your arm, overusing your arm, and sports and work accidents. Depending on the level of injury, you may experience a complete laceration of the radial nerve.
