Bifurcated ligament

The bifurcated ligament (internal calcaneocuboid, interosseous ligament, 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 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 is attached to the lateral side of the navicular.
