Ligament suppoing the head of talus ?
Plantar calcaneonavicular ligament Spring ligament (Plantar calcaneonavicular ligament) connects the calcaneum with the navicular bone. o However, its principal job is to provide a sling for the talus, to suppo the head of talus (though it has no attachment to talus). This aids in suppoing the weight of the body. Weaknes or lengthening along this ligament can cause flat foot.
