Anatomy of the ankle
The ankle is a complex region consisting of three separate joints which are responsible for producing the following actions:
The talocrural joint is created by the tibia, fibula and talus bones. It is responsible for dorsiflexion (pulling your foot towards the sky) and plantarflexion (pointing your foot towards the ground).
The inferior tibiofibular joint is created by the tibia and the fibula bones and is responsible for stabilising the lower shin and the ankle.
The subtalar joint is formed by the talus and the calcaneus bones and is responsible for inversion (turning your ankle in) and eversion (turning your ankle out).
