Foot skeleton

The skeleton of the foot: seven tarsal bones, five metatarsals, fourteen phalanges and the sesamoids under the first metatarsal head.

What to look at

1The hindfoot is the talus and calcaneus; the midfoot is the navicular, cuboid and three cuneiforms; the forefoot is the metatarsals and phalanges.
2Chopart's joint (talonavicular and calcaneocuboid) separates hindfoot and midfoot; Lisfranc's joint (tarsometatarsal) separates midfoot and forefoot.
3The second metatarsal base is recessed between the cuneiforms — the keystone of the Lisfranc joint, held by the Lisfranc ligament from the medial cuneiform.
4The hallux has two phalanges; two sesamoids in flexor hallucis brevis lie under the first metatarsal head.

Hotspots

1Calcaneus — The largest tarsal bone; fractures follow axial loading such as a fall from height.
2Talus — No muscle attachments and about 60% covered in cartilage; neck fractures risk avascular necrosis of the body.
3First metatarsal — Carries about a third of forefoot load.
4Hallux proximal phalanx — The big toe has two phalanges.
5Sesamoid — Medial (tibial) and lateral (fibular) sesamoids within flexor hallucis brevis.
6Base of fifth metatarsal — Peroneus brevis inserts on the tuberosity; Jones fractures are at the metaphyseal–diaphyseal junction.
