Ankle Anatomy

Bony anatomy:

The ankle joint proper has 85% of the load between the lower tibia and the talus, 15% between the distal fibula and the talus.

The foot comprises the hindfoot (calcaneus, talus) midfoot (navicular, cuboid, cuneiforms) and forefoot (metatarsals and phalanges)

There are various tough ligaments that provide stability, notably around the ankle joint.


Medial (inner side) of ankle

Deep Deltoid runs from medial malleolus to talus
Superficial Deltoid divided into four bands:

  • Tibionavicular 

  • Anterior talotibial

  • Calcaneotibial

  • Posterior talotibial
