Definition
The head of talus points forward, downward, and inward, featuring a rounded shape that enables it to connect with the concave rear part of the navicular bone.
The rounded articulating surface extends downward, creating three more joint surfaces below the head. These comprise an anterior facet, a middle facet, and an additional medial (or inner) facet:
The anterior and middle talar facets connect with the corresponding anterior and middle articular facets on the calcaneum.
The inner facet links with the calcaneonavicular ligament, also known as the spring ligament. This ligament passes under the head of talus, connecting the calcaneum with the navicular bone.
