Intraplexal nerve transfers refer to transfers where a healthy nerve of the brachial plexus will be used in order to restore the function of a damaged nerve of the brachial plexus. A classic example of an intraplexal nerve transfer is the Oberlin transfer during which fascicles the ulnar nerve (that ordinarily serves the lower arm) are re-routet to the biceps branch of the musculocutaneous nerve in order to restore the biceps function .In this way the ulnar nerve is not being considerably damaged and its function is preserved. By employing this procedure individual nerve fascicles of the brachial plexus can be used to bring back to life other injured nerves.
Another example consists the use of a purely motor nerve branch ( responsible only for the function and firing of a muscle) of the triceps muscle. In this particular case there are several muscle branches from which one or two could be sacrificed and used for a nerve transfer without causing deficits. These can then used for the restoration of an affected shoulder muscle (deltoid) by transferring them to one of the injured muscle branches ( triceps to axillary transfer).
