During routine anatomical dissection a rare case of a flexor digitorum accessorius (FDA) muscle connected through fibrous slip to flexor hallucis longus (FHL) was observed. The muscle belly of FDA inserted into the tendon of flexor digitorum longus (FDL) at the point where it received a fibrous slip from the tendon of FHL and where it divided into its four tendons. In this case the tendon of FHL instead of connecting to the tendon of FDL connected directly to the medial head of FDA muscle. The possible clinical implications of this may be with the more efficient functioning of the foot in take off and tip toe positions.
