Peroneus tertius (fibularis tertius) muscle is peculiar to man and man is the only member among the primates in whom this muscle occurs. The muscle is variable in its development and attachment, such variants being of considerable morphological significance. Peroneus tertius is highly variable in its form and muscle bulk, but is rarely completely absent. Because of functional demands of bipedal gait and plantigrade foot, part of extensor digitorum brevis has migrated upwards into the leg from the dorsum of foot. During routine dissections with the purpose of preparation of the teaching and museum specimens, in the left leg of a 65 years old male cadaver, we observed variation in the origin and insertion of peroneus tertius muscle. Awareness and precise knowledge of such anatomical variants are important to surgeons performing reconstructive surgery and muscle transposition with retention of function.
