Ankle Dislocation Anatomy

To better understand ankle dislocation, it helps to understand the anatomy of the ankle joint.

The ankle consists of three bones:

  • The tibia is the large, long bone in the lower leg.
  • The fibula is the thin, long bone in the lower leg.
  • The talus lies on top of the heel bone and supports the tibia.

  • Tibia and fibula
  • Side view of ankle bones
  • Front view of ankle bones on x-ray

These three bones are bonded together by strong bands, called ligaments. The ligaments, muscles and tendons keep the bones of the ankle together during movement.

  • Inner aspect of ankle joint
  • View from behind the ankle joint
  • Outer aspect of ankle joint
