Median Neuropathy of the Elbow - The median nerve courses with the brachial artery and travels between the the two heads of the pronator teres giving function to the muscles . The AIN gives muscle function to the thumb flexor, while the FDS powers the index and middle and the pronator quadratus. The median nerve supplies the muscles of the forearm and many functions of the hand. Two possible points of median nerve compression can occur. The first is between the two heads of the pronator teres and the second is the area between the origin of the FDS .
Compression can result from tight fascial bands, anomalous muscles, or trauma.
The symptoms involve the Pronator Syndrome or the AIN Compression Syndrome. Pronator Syndrome exhibits the slow onset of aching pain at the proximal forearm or elbow. Further, numbness and tingling in the fingers occurs and difficulty in fine motor tasks such as buttoning of a shirt. The AIN Syndrome exhibits the sudden onset of pain in the forearm followed by motor weakness of paralysis. The Pronator Syndrome can be treated conservatively if there is no weakness of muscles after rest period.
