Which bone articulates proximally with the talus and distally with the three cuneiforms?

• A. Navicular
• B. Cuboid
• C. First metatarsal
• D. Calcaneus

Answer: (A)

The bone that connects the hindfoot to the midfoot is the navicular. It sits between the talus above and the three cuneiforms below. Proximally, the navicular has a facet that forms the talonavicular joint with the talus, allowing movement between the hindfoot and midfoot. Distally, it presents three articular facets that align with the medial, intermediate, and lateral cuneiforms, creating three navicular–cuneiform joints that link the navicular to the forefoot. This central position makes the navicular the keystone of the medial column and essential for the integrity and mechanics of the medial longitudinal arch. The other bones listed either do not bridge between the talus and all three cuneiforms or are positioned differently in the foot's architecture.
