Dislocated Ankle 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.
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.
