Description
The retinacula of the ankle are fascial thickenings that create tunnels for which tendons, vessels, and nerves can pass from the leg into the foot. The term retinaculum is derived from the Latin “to retain,” and thus, they retain the tendons and prevent subluxation.
The retinacula of the ankle include:
—the superior and inferior extensor retinacula;
—the superior and inferior fibular retinacula;
—flexor retinacula.
