How to Remember the Tarsal Bones
Seven bones in the ankle and foot. One classic mnemonic. Then flashcards to lock it in.
The tarsal bones are the seven bones that form the ankle and posterior half of the foot. They arrange in three groups: proximal (talus, calcaneus), intermediate (navicular), and distal (cuboid plus three cuneiforms). Anatomy exams love them because there are just enough to be confusing.
The classic mnemonic
'Tiger Cubs Need MILC' or 'Tall Californians Never Make Interesting Little Countries.'
- T — Talus
- C — Calcaneus
- N — Navicular
- M — Medial cuneiform
- I — Intermediate cuneiform
- L — Lateral cuneiform
- C — Cuboid
Grouping by row
Proximal: talus (top, articulates with tibia and fibula), calcaneus (heel).
Intermediate: navicular (between talus and cuneiforms).
Distal: three cuneiforms (medial, intermediate, lateral) articulating with metatarsals 1–3, and cuboid articulating with metatarsals 4–5.
Clinical high-yield
Calcaneus fracture — the classic fall-from-height injury; associated with vertebral compression fractures. Talar neck fracture — high risk of avascular necrosis. Navicular stress fracture — a common overuse injury in runners.
Frequently asked questions
Do the cuneiforms have a directional trick?
Medial, intermediate, lateral matches the first three metatarsals (big toe side to third-toe side). Cuboid articulates with fourth and fifth metatarsals.
Is talus or calcaneus the ankle bone?
Talus. It articulates with the tibia and fibula at the ankle joint. Calcaneus is the heel bone below.
Any Step 1 relevance?
Calcaneus fracture presentation is highest-yield. Talar neck fracture and Chopart / Lisfranc joint injuries also appear.
What is the Lisfranc joint?
The tarsometatarsal joint — where the tarsal bones meet the metatarsals. Lisfranc injuries are commonly missed on plain X-ray.
How does this fit with foot arches?
The tarsal bones form the arches — medial longitudinal, lateral longitudinal, and transverse. Navicular is the keystone of the medial longitudinal arch.
