- There are seven tarsal bones of the ankle region.
- talus, calcaneus, navicular, cuneiforms, cuboid.
- There are three cuneiforms: first, second, and third (sometimes named medial, middle, and lateral).
- The tarsals articulate with:
- the tibia and fibula proximally, forming the ankle (talocrural) joint.
- the metatarsals distally, forming the tarsometatarsal joints.
- each other, forming the subtalar, transverse tarsal, and other joints.
NOTES:
- 70% of the talus is articular surface. No muscle attaches to the talus.
- The subtalar joint is located between the talus and calcaneus.
- There are seven tarsal bones but eight carpal bones, because the pisiform of the carpals is a sesamoid bone that formed later evolutionarily.
