Posterior aspect of left ankle and foot
Peroneus accessorius muscle; long flexor tendons in relation to ankle, posterior view
The peroneus longus and brevis muscles have been cut off. A peroneus accessorius muscle (7) is present with a small muscular portion attached to the lateral side of the calcaneus and a slender tendon extending upward to blend with the posterior intermuscular septum of the leg. The calcaneal tendon has been divided slightly above its attachment of the calcaneus.
