Broken Ankle

What is an ankle fracture?

This is a difficult question to answer. The ankle is a complex joint that forms where three bones come together. The bones of the lower leg, the tibia and the fibula, are above the joint, and the talus is below the joint. When a doctor talks about an ankle fracture, he or she is usually talking about a broken bone of the tibia or fibula.

The tibia, also called the shin bone, is the larger, weight-bearing bone of the lower leg. Of the weight transferred through the leg, about 90% is carried by the tibia. The fibula is the smaller bone on the outside of the leg. It only carries about 10% of your body weight.

Both the tibia and the fibula wrap around the talus to form the ankle joint. The bony prominences at the ankle are called the medial malleolus (the end of the tibia) and the lateral malleolus (the end of the fibula). The ends of these bones for a cup for the talus to sit within.

The Broken Ankle

When a broken ankle occurs, the injury may be to the end of the tibia (the medial malleolus) or to the fibula (the lateral malleolus), or both. There are many different type of ankle fractures, and attempting to discuss them is the subject of textbooks, not pamphlets like this. The point is, every ankle fracture MUST be treated individually. You must see your doctor and go over the treatment plan with him or her.
