Abstract

The extensor indicis proprius muscle (EIP) originate from the proximal two-thirds of the distal half of interosseous line of ulna, the adjacent interosseous membrane and frequently the fibrous septum of the extensor pollicis longus and the dorsal ulnar septum. Variation of EIP is include complete absence or some change of its origin or insertion. But it is very rare and there is no report about its variation in our country as we know. Of variation, short form of EIP is relatively well known and is called Extensor indicis brevis or Extensor digitorum brevis manus. We present a case of a extensor tenosynovitis associated with extensor indicis brevis muscle at wrist level.

Key Words: Hand, Extensor indicis brevis, Tenosynovitis
