Calcaneonavicular ligament

The bifurcate ligament is a strong band, attached behind to the deep hollow on the upper surface of the calcaneus and dividing in front in a Y-shaped manner into a calcaneocuboid and a calcaneonavicular part.

• The calcaneocuboid part (Calcaneocuboid ligament) is fixed to the medial side of the cuboid and forms one of the principal bonds between the first and second rows of the tarsal bones.
• The calcaneonavicular part (Calcaneonavicular ligament) is attached to the lateral side of the navicular.
