Radial nerve dysfunction is a problem associated with the radial nerve resulting from injury consisting of acute trauma to the radial nerve. The damage has sensory consequences, as it interferes with the radial nerve's innervation of the skin of the posterior forearm, lateral three digits, and the dorsal surface of the lateral side of the palm. The damage also has motor consequences, as it interferes with the radial nerve's innervation of the muscles associated with the extension at the elbow, wrist, and fingers, as well the supination of the forearm.[1] This type of injury can be difficult to localize, but relatively common,[2] as many ordinary occurrences can lead to the injury and resulting mononeuropathy. One out of every ten patients with radial nerve dysfunction do so because of a fractured humerus.[3]
