More Information about the Pronator Teres Muscle

The ulnar head of the pronator teres muscle is sometimes absent.  Pronator teres syndrome is a type of neurogenic pain due to compression of the median nerve of the elbow.  A common symptom of pronator teres syndrome is  numbness in median nerve distribution with repetitive pronation/supination of the forearm.
