Extensor Digitorum Communis

Lateral (wrist extensor) and supinator Supplied by the radial and the posterior interosseous nerve, this group consists of the supinator, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum communis, and the extensor carpi ulnaris. 

Over the shaft of the radius at mid-forearm. The electrode will travel through the extensor digitorum communis. 

If the electrode is inserted too proximally it will be in the extensor carpi radialis brevis if inserted too distally it will be in the extensor pollicis brevis if it is inserted too ulnarly or too superficial, it will be in the extensor digitorum communis.

Joins ulnar side of tendon of extensor digitorum communis, which goes to index finger terminates in extensor expansion.
