RESUMEN
It was found an unusual anatomical variation in a male cadaver that is consistent with the existence of anaccessory muscle in the posterior area of the third distal of the forearm. Such structure arises in the posteriorface of ulna and is fixed in the back of the proximal phalange of the middle finger. The described variation isalso useful to the hand surgeon, as the anomalous muscle is an anatomical landmark for operations at this area.To our knowledge, this variation has not been cited in recent medical literature.

This study describes a rare case of the accessory muscle originated from the flexor carpi ulnaris muscle. Anunusual variation of the flexor muscle was observed during the male cadaver dissection. The presence of ananatomical variation muscle was verified in the forearm on the left side of a 59 year old corpse settled in formol10%. Morphological variability and clinical significance are reviewed.
