Tarsal Bones Mnemonic
Remembers the seven tarsal bones of the foot. The talus articulates with the tibia, and the calcaneus forms the heel. The navicular and cuneiforms form the medial arch.
The Mnemonic
"Tiger Cubs Need MILC (Medial, Intermediate, Lateral Cuneiform)"
Breakdown
Talus
Superior tarsal, articulates with tibia and fibula at ankle
Calcaneus
Largest tarsal, forms the heel, Achilles tendon attachment
Navicular
Boat-shaped, medial side, tibialis posterior attaches here
Medial Cuneiform
Largest cuneiform, articulates with 1st metatarsal
Intermediate Cuneiform
Smallest cuneiform, articulates with 2nd metatarsal
Lateral Cuneiform
Articulates with 3rd metatarsal and cuboid
Cuboid
Lateral side, articulates with 4th and 5th metatarsals
Clinical Relevance
Talus fractures can cause avascular necrosis due to tenuous blood supply. Calcaneus fractures from falls cause Bohler's angle flattening. Navicular stress fractures common in athletes.
Study Tips
- ✓Talus sits on calcaneus like a rider on a horse
- ✓Navicular is only on the medial side (navicular = boat, navigates medially)
- ✓Cuboid is only on the lateral side (cube is square, stands alone)
- ✓Three cuneiforms go to first three metatarsals
FAQs
Common questions about this mnemonic
The talus has no muscle attachments and limited blood supply entering through the neck. Fractures, especially displaced neck fractures, can disrupt blood flow causing bone death.
Bohler's angle measures calcaneus shape on lateral X-ray (normally 25-40°). Compression fractures from falls flatten this angle. Decreased angle indicates fracture severity and helps guide surgical vs conservative treatment.
