Ankle Joint Anatomy

Ankle Joint

• Tibia – shinbone
• Fibula – smaller bone of the lower leg
• Talus – a small bone that sits between the heel bone (calcaneus) and the tibia and fibula

The ankle joint is stabilised by ligaments (strong bands that hold bones together) on the inside and outside. The outside ligaments are much more commonly injured because we tend to roll our foot inwards (as shown in the illustration), resulting in chronic ankle instability.
