Structure
The bifurcate ligament is a strong ligament that arises from the anterior part of the dorsal surface of the calcaneus. As its name suggests, the ligament bifurcates forming a Y-shaped ligament. One arm of the Y, referred to as the calcaneocuboid part, extends to the dorsal surface of the cuboid bone, while the other arm, the calcaneonavicular part, extends to the lateral surface of the navicular bone.
