Abstract:
Most of the anatomical variations are noted during the cadaveric dissections. A rare variation of the Extensor digitorum brevis manus was observed on the dorsal aspect of the right hand of a 69-year-old male cadaver. This atavistic muscle had two bellies which originated from the dorsal aspect of the lower end of radius and the capsule of the wrist joint respectively. The two bellies fused to form a single tendon which inserted into the ulnar side of the dorsal digital expansion of the middle finger. Posterior interosseous nerve innervated the two bellies. This muscle may be involved in the wrist pain or may be misinterpreted as a ganglion or a nodule upon radiological examination. This muscle may be used for reconstructive purposes.

KEY WORDS: Extensor digitorum brevis manus, Fourth compartment syndrome, Posterior interosseous nerve, Wrist pain.
