Surgical importance of the interconnection between the tendons of flexor digitorum longus and flexor hallucis longus is applied in the tendon transfer surgery in patients with tibialis posterior dysfunction, and in reconstruction of chronically ruptured Achilles tendon. The anatomical distal connection of these tendons varies considerably and the presence of strong link in the region of Knot of Henry can preserve distal function if one of the tendons is used for transfer surgery. The present case is of a connecting tendinous slip from flexor digitorum longus to flexor hallucis longus tendons in the left foot and from flexor hallucis longus to flexor digitorum longus tendons in the right foot. The importance of such variations is to be kept in mind during radiodiagnostic procedures and surgical interventions.
