Flexor Retinaculum of Foot

Last Updated: Jun 25, 2015

The flexor retinaculum of the foot runs (posteriorly, on the inside) between the medial malleolus (network of nerve tissues and muscle around the ankle) and the calcaneus (Achilles tendon) and forms sheaths for tendons passing beneath the foot. There is a corresponding flexor retinaculum in the wrist and palm of the hand.
