ABSTRACT
The supernumerary fascicles of abductor digiti minimi muscle have been implicated in vascular and nerve compression. During routine dissection of an old male cadaver we observed an anomalous muscle was found to take it's origin from the antebrachial fascia and flexor retinaculum, traversed ulnar canal (Guyon's) superficial to ulnar vessels and nerves to reach the proximal part of abductor digiti minimi. The anomaly is one of a kind. Its course through Guyon's canal could be a cause for Guyon's canal syndrome. It was innervated by the ulnar nerve.
RESUMEN
Los fascículos supernumerarios del músculo abductor del dedo mínimo han sido implicados en la compresión neurovascular. Durante una disección de rutina de un cadáver masculino adulto, se observó un músculo anómalo que se originaba en la fascia antebraquial y en el retináculo flexor, atravesaba el canal ulnar, superficial a los vasos y nervio ulnares para llegar a la parte proximal del músculo abductor del dedo mínimo. La anomalía es única en su tipo. Su curso a través del canal ulnar puede causar el síndrome del canal ulnar. El músculo estaba inervado por el nervio ulnar.
