AN ACCESSORY FLEXOR DIGITORUM LONGUS MUSCLE

An accessory flexor digitorum longus muscle (M. flexor digitorum longu s accessorius) in a 60-year-old male cadaver was encountered during ro utine dissections in our laboratory. The muscle originated from the de ep transverse fascia of the leg, covering flexor digitorum longus, fle xor hallucis longus, and tibialis posterior muscles, and additionally from some fibres of these muscles. After the tendon of the muscle pass ed behind the medial malleolus, it inserted into the tendon of the fle xor digitorum longus muscle where the latter separated into four digit al tendons.
