The superior extensor retinaculum of the foot (transverse crural ligament) is the upper part of the extensor retinaculum of foot which extends from the ankle to the heelbone. The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on ...
The flexor retinaculum of the foot extends from the medial malleolus above, to the calcaneus below. [1] This converts a series of bony grooves into canals for the passage of the tendons of the flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot, known as the tarsal tunnel.
The term retinaculum is Neo-Latin, [2] derived from the Latin verb retinere (to retain). Specific retinacula include: In the wrist: Flexor retinaculum of the hand; Extensor retinaculum of the hand; In the ankle: Flexor retinaculum of foot; Superior extensor retinaculum of foot; Inferior extensor retinaculum of foot; Superior fibular retinaculum
The inferior extensor retinaculum of the foot (cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front ...
The muscle passes under the superior and inferior extensor retinaculum of foot in company with the fibularis tertius, and divides into four slips, which run forward on the dorsum of the foot, and are inserted into the second and third phalanges of the four lesser toes.
The fibular retinacula (also known as peroneal retinacula) are fibrous retaining bands that bind down the tendons of the fibularis longus and fibularis brevis muscles as they run across the side of the ankle. (Retinaculum is Latin for "retainer.") These bands consist of the superior fibular retinaculum and the inferior fibular retinaculum.
