描述

The fibular retinacula (peroneal retinacula) are fibrous bands which bind down the tendons of the Peronæi longus and brevis as they run across the lateral side of the ankle.

  • The fibers of the superior retinaculum (external annular ligament) are attached above to the lateral malleolus and below to the lateral surface of the calcaneus.
  • The fibers of the inferior retinaculum are continuous in front with those of the cruciate crural ligament; behind they are attached to the lateral surface of the calcaneus; some of the fibers are fixed to the peroneal trochlea, forming a septum between the tendons of the Peronæi longus and brevis.
