Peroneus Tertius

Peroneus tertius varies in size; it may be as large as the extensor digitorum longus or it may be absent. This muscle is peculiar to humans, and represents the extensor digiti minimi (proprius) (pedis) with its insertion displaced to the base of the fifth metatarsal. It often inserts onto the base of the fourth metatarsal as well. It is not so completely separated from the common extensor at its origin as is the corresponding muscle of the forearm. A slip occasionally joins the extensor tendon of the fourth and little toe or fourth interosseus, and represents the radial tendon of extensor digiti minimi (proprius); its main tendon corresponds to the ulnar slip in the hand.

Macalister reports peroneus tertius as follows:

1. The muscle may be absent (~1/10 subjects);

2. It may be doubled;

3. Or it may have a doubled tendon;

4. Or send a tendinous slip to the fourth metatarsal;

5. Or may go entirely to this bone;

6. As a mere tendinous band from extensor communis;

7. Sending a slip to extensor aponeurosis of the little toe;

8. Or a slip to the lateral tendon of the long extensor;

9. Or to the corresponding tendon of the short extensor (Bahnsen);

10. With a doubled tendon, one part of which went to the fascia over the fourth interosseous muscle;

11. Arising from the lower half of the fibula;

12. Sending off the extensor tendon to the little toe in a case in which no such tendon arose from the long extensor;

13. Doubled, the posterior muscle having two tendons to the fifth metatarsal, the anterior sending slips to the little toe and fourth metatarsal.
