The inferior extensor retinaculum is a sheet of connective tissue that crosses over the front of the ankle in a Y-shape from the outside of the foot toward the arch. The tissue formations in various regions of the ankle are thickened to form such retinacula in sheaths to hold tendons down as they are crossing the front of the ankle.
